Urocitellus brunneus

Tiny microplastic fragments, often smaller than a grain of rice, are turning up in surprising places. From city streets to remote oceans, they persist in the air, water, and soil. 



Scientists have learned that these particles can also invade the human body, showing up in organs that keep us alive. 



For years, researchers have warned us about the possible dangers microplastics pose to animals, our food sources, and human health. Now a fresh study suggests even plants are feeling the pressure.



<h2 class="wp-block-heading" id="h-plants-photosynthesis-and-microplastics">Plants, photosynthesis, and microplastics</h2>



This new research from <a href="https://www.5gyres.org/" target="_blank" rel="noreferrer noopener">5 Gyres Institute</a> offers new clues about how these plastic particles affect photosynthesis. 



The team gathered over 3,200 records from across the globe, focusing on how tiny bits of microplastics alter photosynthesis by changing the way <a href="https://www.earth.com/news/details-photosynthesis-water-viewed-atomic-level-cryo-microscope/" target="_blank" rel="noreferrer noopener">plants use sunlight</a> to produce energy. 



Their analysis spans common food crops and aquatic species, highlighting concerns about weakened growth. 



For communities that rely on healthy harvests and marine resources, these findings add a fresh dimension to the worldwide plastic conversation.



“It’s really scary,” says Marcus Eriksen, a marine scientist at the 5 Gyres Institute, a nonprofit plastic pollution research organization, who was not involved in the study.



<h2 class="wp-block-heading" id="h-how-microplastics-spread-far-and-wide">How microplastics spread far and wide</h2>



Most microplastics come from everyday sources. Plastic bottles, packaging, and synthetic clothing shed fibers that break into smaller pieces. Rain and wind carry these particles into rivers, and eventually they end up in oceans. 



In agricultural fields, plastic mulch or irrigation systems contribute fragments that seep into the soil. Over time, these bits degrade further, leading to a steady accumulation in places we least expect. 



This constant spread worries experts because smaller sizes mean they can slip into living organisms more easily.



Researchers have found these particles in fish, shellfish, and even table salt. In recent years, labs have also identified plastic remnants in bottled water and tap supplies. 



While ongoing investigations continue to measure how widespread they are, one thing is clear: once plastic breaks down, it does not disappear. That lingering presence has potential consequences for all life on Earth.



<h2 class="wp-block-heading" id="h-microplastics-impede-photosynthesis">Microplastics impede photosynthesis</h2>



In this new analysis, researchers show that microplastics reduce photosynthesis by 7 to 12% across different plant species. 



A computer model backs this up, indicating that plastic particles can <a href="https://www.earth.com/news/artificial-photosynthesis-could-transform-power-generation/" target="_blank" rel="noreferrer noopener">lower chlorophyll</a> levels by 11 to 13%. 



<a href="https://www.earth.com/news/gardening-hack-called-green-gold-chlorophyll-works-like-magic-for-houseplants/" target="_blank" rel="noreferrer noopener">Chlorophyll</a> is the green pigment that helps plants capture sunlight for food production, so any dip in its presence can affect overall growth.



Every year, this pollution could cause a loss of 109 to 361 million metric tons of crops and 1 to 24 million metric tons of seafood, according to the study. 



Because of microplastic buildup, global harvests may drop by 4 to 13% yearly, and food from the ocean could decline by up to 7%. 



Even minor disruptions to plant growth may have ripple effects on human nutrition and economies that rely on farming.



<h2 class="wp-block-heading" id="h-challenges-for-the-food-supply">Challenges for the food supply</h2>



Beyond plants, these particles also affect marine life, which many communities rely on for protein. Scientists report that if <a href="https://www.earth.com/news/microplastic-pollution-is-everywhere-even-in-newborns-and-getting-worse/" target="_blank" rel="noreferrer noopener">microplastic pollution</a> continues unchecked, seafood yields could suffer even further. 



They are associated with an increase in people’s risk of heart attack and stroke, and they have been found to hamper growth and reproduction in multiple species. 



Worries about <a href="https://www.earth.com/news/we-are-in-a-race-against-time-to-save-our-food-supply-from-climate-change/" target="_blank" rel="noreferrer noopener">food safety and supply</a> also arise when these pollutants accumulate in organisms that people eat.



Researchers suggest that a modest 13% reduction in these particles could prevent the loss of up to 47 million metric tons of crops and 3 million metric<a href="https://www.earth.com/news/plastic-particles-found-in-99-of-tested-seafood-samples/" target="_blank" rel="noreferrer noopener"> tons of seafood</a> each year, translating to a 30% cut in overall harm. 



This projection highlights the importance of tightening plastic regulations and improving waste management to protect food resources.



<h2 class="wp-block-heading" id="h-why-does-any-of-this-matter">Why does any of this matter?</h2>



Reduced photosynthesis does not only <a href="https://www.earth.com/news/microbial-awakening-arctic-food-webs-are-transforming-from-green-to-brown/" target="_blank" rel="noreferrer noopener">disrupt food webs</a>. When plants capture less carbon dioxide, there is less natural removal of this greenhouse gas from the atmosphere. 



In many climate strategies, forests and marine algae are expected to absorb significant amounts of carbon in the coming decades. If plastic particles undermine that process, climate models may need to be revised.



Most projections assume stable plant performance over time. Any drop in growth or carbon uptake could make <a href="https://www.earth.com/news/un-the-world-is-on-track-for-a-catastrophic-level-of-global-warming/" target="_blank" rel="noreferrer noopener">global warming</a> harder to control. 



With ecosystems already under stress, additional strain from microscopic plastic fragments raises concerns about future carbon storage in forests, grasslands, and kelp beds.



<h2 class="wp-block-heading" id="h-sounding-the-alarm">Sounding the alarm</h2>



The study’s authors emphasize the need for international efforts to address plastic waste, pointing out that large pieces eventually degrade into smaller and more invasive forms.



A global treaty on plastic issues has been in discussion since 2017, yet recent negotiations concluded without a formal agreement.



Marine biologist Richard Thompson, who specializes in microplastic pollution at the <a href="https://www.plymouth.ac.uk/" target="_blank" rel="noreferrer noopener">University of Plymouth</a> in England and was not involved in the study, notes that delaying action only increases the risks.



“If we don’t take action now,” he adds, “within the next 70 to 100 years, we’ll see much wide-scale ecological harm.”



Researchers say that lowering even a small amount of microplastic pollution could help protect crops, preserve marine life, and support our climate goals.



Taking action now can guard our health and ensure a healthier environment for generations to come, which doesn’t seem like too much to ask of humanity.

Sounding the alarm: Microplastics are disrupting  photosynthesis around the world

Tiny microplastic fragments, often smaller than a grain of rice,...

With spring approaching, many people are already considering which flowers to plant. Flowers do more than simply make gardens look nice. They are an important source of food for birds and insects, particularly wild bees.



In cities, the appropriate combination of flowers can be the difference between healthy bee populations and unhealthy ones.



A recent study has explored how the properties of flowers affect urban <a href="https://www.earth.com/news/flower-strips-can-boost-wild-bee-populations/" target="_blank" rel="noreferrer noopener">bee populations</a>. 



The researchers discovered that a diverse range of flower sizes and shapes is crucial for supporting wild bee populations. A more varied floral landscape promotes a richer and more abundant bee community.



<h2 class="wp-block-heading" id="h-why-flower-shape-and-size-matter">Why flower shape and size matter</h2>



Study co-author Carly Ziter is an associate professor in the Department of Biology in the Faculty of Arts and Science at <a href="https://www.concordia.ca/" target="_blank" rel="noreferrer noopener">Concordia University</a>.



"We know that flowers are an important source of nutrition for bees, but not all flowers are created equal," said Professor Ziter.



"Having a high <a href="https://www.earth.com/news/new-secrets-of-flower-diversity-revealed/" target="_blank" rel="noreferrer noopener">diversity of flowers</a> is a key to supporting bee populations, but our research goes one step further to show a possible mechanism: that having a diversity of floral species is important because they have different shapes and sizes."



Flowers store <a href="https://www.earth.com/news/honeybees-carrying-nectar-avoid-overheating-rising-temperatures/" target="_blank" rel="noreferrer noopener">nectar</a> within their corolla - the tube-like structure formed by a ring of <a href="https://www.earth.com/news/plants-engineer-their-petals-to-be-visually-attractive-to-bees/" target="_blank" rel="noreferrer noopener">petals</a>. Different bee species have different tongue lengths, which means some bees can only access nectar from specific flower shapes.



"This follows the idea of size-matching, where corollas are the right size for a certain type of bee’s proboscis or tongue, allowing it to effectively connect to the flower’s nectar," noted Professor Ziter.



"So, whether a bee has a short or longer proboscis, they will be able to access the nutrition they need if there are multiple kinds of flower morphology nearby."



<h2 class="wp-block-heading" id="h-tracking-bees-in-the-city">Tracking bees in the city</h2>



The team collected data in July 2020 from 16 sites across the Island of Montreal, including community gardens, nature parks, and cemeteries.



The researchers recorded nearly 2,000 bee samples and identified 150 different <a href="https://www.earth.com/news/study-reveals-that-90-of-flowering-plant-species-rely-on-animal-pollinators/" target="_blank" rel="noreferrer noopener">species of flowers</a> within small two-by-two-meter plots.



The density of flowers was measured, and the size of each corolla was documented using digital calipers.



A total of 94 different species of bees were observed during the study. While nectar samples were also collected, no firm connection was established between sugar content and bee diversity.



<h2 class="wp-block-heading" id="h-plant-diversity-and-the-food-web">Plant diversity and the food web</h2>



"We wanted to see if there was an optimal value for corolla traits," said Professor Ziter. "Was it better to have small corollas, medium ones, or a diversity of them? The results showed quite strongly that having a diversity of corolla sizes was important."



Thriving bee populations play a vital role in <a href="https://www.earth.com/news/robotic-insects-may-be-the-future-of-farming-and-plant-pollination/" target="_blank" rel="noreferrer noopener">pollination</a>, supporting entire ecosystems and sustaining food supplies.



According to Professor Ziter, the study supports the belief that a diversity of flowers impacts the next trophic level, which contributes to an ecosystem’s food web in a way that goes far beyond bees. 



<h2 class="wp-block-heading" id="h-how-to-make-your-garden-bee-friendly">How to make your garden bee-friendly</h2>



City planners, gardeners, and anyone interested in promoting biodiversity can apply these findings in practical ways.



"If you are planting, try to think about what makes these species different. Are they different colors? Are they different sizes? Do they bloom at different times? The more you can think about these different axes of variety in your own garden, the more you are likely to be better off in terms of supporting biodiversity," said Professor Ziter.



By planting a diverse mix of flowers, urban residents can play a small but significant role in sustaining local bee populations and contributing to a healthier environment.



<h2 class="wp-block-heading" id="h-choosing-the-right-flowers-for-bees">Choosing the right flowers for bees</h2>



For a bee-friendly garden, native plants are often the best choice since they have co-evolved with local species and provide the most suitable nectar and pollen.



Flowers with open, accessible petals are ideal for short-tongued bees, while tubular flowers cater to species with longer proboscises.



Bloom timing is another crucial factor. By planting a variety of flowers that bloom at different times throughout the growing season, gardeners can ensure a steady food supply for bees from early spring to late fall. 



Perennial flowers such as coneflowers, milkweed, and goldenrod are excellent choices, as they return each year and require minimal maintenance.



Avoiding pesticide use and opting for organic gardening practices further enhances the bee-friendly environment.

Bee-friendly gardening: Why flower diversity is so important

With spring approaching, many people are already considering which flowers...

Grasslands, once vibrant ecosystems teeming with diverse plant and animal life, are vanishing at an alarming rate. Land-use changes, urban expansion, and agricultural development have led to their decline. Abandoned grasslands can be restored through proper management, but full recovery takes longer than expected.



A study from <a href="https://www.kobe-u.ac.jp/en/" target="_blank" rel="noreferrer noopener">Kobe University</a> reveals that even after 75 years of continuous management, restored grasslands do not match the biodiversity of ancient ones. The slow return of specialized pollinators plays a key role in this delay. 



These findings highlight the need to protect old <a href="https://www.earth.com/news/restored-grasslands-bring-more-peace-to-africa/" target="_blank" rel="noreferrer noopener">grasslands</a>, even when they serve modern purposes like ski slopes.



<h2 class="wp-block-heading" id="h-why-restored-grasslands-lag-behind">Why restored grasslands lag behind</h2>



Grasslands undergo massive ecological shifts when left unmanaged. Woody vegetation overtakes the landscape, reducing the diversity of native grassland species. <a href="https://www.earth.com/news/controlled-fires-can-help-us-save-grasslands-from-disappearing/" target="_blank" rel="noreferrer noopener">Restoration efforts</a> involve clearing invasive plants and reintroducing traditional management practices. 



While this process improves biodiversity, researchers have found that restored grasslands still struggle to match the richness of ancient ones.



“The reasons for this are not really clear and satisfying solutions have not been proposed,” noted Kobe University ecologist Ushimaru Atushi. 



Even when restored, grasslands seem unable to support the same variety of plant species as those that have been maintained for centuries. This realization led researchers to investigate the role of pollinators in the recovery process.



<h2 class="wp-block-heading" id="h-pollinators-and-grassland-recovery">Pollinators and grassland recovery</h2>



Pollinators play an essential role in maintaining plant diversity. Without them, many plant species struggle to reproduce. Insect-pollinated plants, in particular, take longer to return after <a href="https://www.earth.com/news/some-grassland-ecosystems-handle-climate-change-better-than-others/" target="_blank" rel="noreferrer noopener">grassland</a> abandonment. 



Ushimaru and doctoral student Hirayama Gaku set out to examine how pollinator communities differ between old and newly restored grasslands.



The team selected ski slopes in Nagano Prefecture for their research. These sites provided a unique opportunity to study grasslands of different ages within a relatively small area.



“There is no place better suited to survey restored grasslands with very different management durations within a relatively small area than ski slopes,” noted Hirayama.



<h2 class="wp-block-heading" id="h-why-75-years-is-not-enough">Why 75 years is not enough</h2>



The research, published in the Journal of Applied Ecology, confirms that even after 75 years, restored grasslands do not support the same pollinator diversity as ancient ones. While plant species may recover, pollinators remain less specialized and less efficient in transferring pollen.



Over time, the pollinator community gradually shifts, becoming more specialized. However, this process takes centuries rather than decades. “The finding shows that once valuable old grasslands are lost, their restoration cannot be achieved quickly," said Hirayama.



The problem isn’t the number of pollinators - it’s their diversity. Restored grasslands welcome flies and hoverflies, generalists that mix pollen between different plants.



In contrast, ancient <a href="https://www.earth.com/news/grasslands-crucial-role-global-agriculture-environment-ecosystems/" target="_blank" rel="noreferrer noopener">grasslands</a> support more bees and butterflies, which specialize in pollinating specific plants. This specialization ensures that pollen reaches the right flowers, increasing plant reproduction success.



<h2 class="wp-block-heading" id="h-strategies-for-restoring-grasslands">Strategies for restoring grasslands</h2>



Restoring grasslands isn’t just about plants; pollinators matter too. Ancient grasslands give specialized pollinators a place to thrive. Without them, rare plant species struggle. 



Protecting these old ecosystems keeps biodiversity alive and flourishing. Ushimaru suggests that natural restoration alone may not be enough.



“It may also indicate that grassland restoration should not just be left to nature, but could require active human involvement such as by sowing seeds or by planting seedlings of native bee- and butterfly-pollinated grassland plants,” said Ushimaru.



This approach could speed up the recovery process, helping pollinator communities establish themselves more quickly.



<h2 class="wp-block-heading" id="h-long-term-conservation-efforts">Long-term conservation efforts</h2>



Restoring grasslands requires patience, commitment, and proactive strategies. The findings from Kobe University demonstrate that even a lifetime of restoration is not enough to fully rebuild lost ecosystems. Old grasslands, shaped by centuries of ecological interactions, provide irreplaceable value to biodiversity.

Restored grasslands could take centuries to fully recover

Grasslands, once vibrant ecosystems teeming with diverse plant and animal...

A recent investigation shows that large, unbroken forests support more biodiversity than fragmented landscapes. 



While ecologists have long known that habitat loss contributes to declines in biodiversity within forest remnants, a debate persisted about whether conserving several smaller plots or one larger tract is more beneficial. 



This study - published in the journal <a href="http://dx.doi.org/10.1038/s41586-025-08688-7" target="_blank" rel="noreferrer noopener">Nature</a> and directed by <a href="https://umich.edu/" target="_blank" rel="noreferrer noopener">University of Michigan</a> (U-M) ecologist Thiago Gonçalves-Souza – takes a definitive stance, indicating that fragmentation undercuts <a href="https://www.earth.com/news/forest-biodiversity-benefits-from-large-herbivores-like-elephants-and-moose/" target="_blank" rel="noreferrer noopener">biodiversity</a> on multiple levels.



“Fragmentation is bad,” said study co-author Professor Nate Sanders. “This paper clearly shows that fragmentation has negative effects on biodiversity across scales. 



“That doesn’t mean we shouldn’t try to conserve small fragments when we can with our limited conservation dollars, but we need to be wise about conservation decisions.”



<h2 class="wp-block-heading" id="h-global-perspective-on-fragmentation">Global perspective on fragmentation</h2>



The experts examined 4,006 species of vertebrates, invertebrates, and plants gathered from 37 sites worldwide, thereby generating a global overview of biodiversity differences between continuous and fragmented forests. 



The findings suggest a significant drop in <a href="https://www.earth.com/news/tree-species-diversity-makes-forests-more-productive/" target="_blank" rel="noreferrer noopener">species diversity</a> within fragmented zones, illustrating a 13.6% decline at smaller (patch) scales, and 12.1% at broader (landscape) scales.



Additionally, the researchers noticed that generalized species - those flexible enough to thrive in a wide range of settings - tend to dominate in fragments. In contrast, more specialized organisms flourish in intact forests.



<h2 class="wp-block-heading" id="h-alpha-beta-and-gamma-diversity">Alpha, beta, and gamma diversity</h2>



To illustrate the varied impacts of fragmentation, the team looked at alpha, beta, and gamma diversity. Alpha diversity refers to how many species occur in a single piece of forest, whereas beta diversity measures how different species compositions are from one patch to another. 



Gamma diversity represents total biodiversity across a larger region, whether that region is made of disjointed fragments or an uninterrupted forest expanse.



“The heart of the debate is that people who argue that fragmentation isn’t so bad say that because you have isolated habitats, you have different species composition, which means at a large scale, it’s good. If they are different, we can assume that the gamma diversity is going to be higher,” said Gonçalves-Souza.



“They say the opposite for large tracts of land: because this is a continuous and homogeneous patch, the species composition is too similar.”



Previously, much research only covered one aspect of diversity or compared a few continuous forests against numerous fragments, potentially skewing the findings. The new study tackled this imbalance with thorough analyses and corrected for variations in sampling.



“One reason that this has been such a long-standing and unresolved debate is that we simply have not had the appropriate data and statistical tools to systematically evaluate the question at both smaller and larger scales,” noted Jonathan Chase, a professor at the <a href="https://www.idiv.de/" target="_blank" rel="noreferrer noopener">German Center for Integrative Biodiversity Research</a>.



<h2 class="wp-block-heading" id="h-fragmentation-s-clear-impact">Fragmentation’s clear impact</h2>



Gonçalves-Souza and colleagues found that fragmentation lowers species numbers across all groups, and that heightened beta diversity in smaller forest fragments does not compensate for the overall loss of species variety at the wider landscape scale.



“This paper resolves a half-century old debate about how to conserve biodiversity in natural areas, one started by scientific luminaries including E.O. Wilson and Jared Diamond,” said Nick Haddad, a researcher at <a href="https://msu.edu/" target="_blank" rel="noreferrer noopener">Michigan State University</a>.



Alongside reduced biodiversity, scientists argue that fragmentation can also threaten carbon sequestration in forests. 



“People are also comparing these two situations and finding that we are losing the ability for landscapes to store more carbon in fragmented landscapes,” Gonçalves-Souza said. “Fragmented landscapes are not only going to affect biodiversity by decreasing alpha and gamma diversity, but it also has implications for carbon stock as well.”



<h2 class="wp-block-heading" id="h-rethinking-future-conservation-efforts">Rethinking future conservation efforts</h2>



Ultimately, Gonçalves-Souza hopes that the study’s results will move the conservation community beyond debates about whether multiple small fragments or a single extensive forest is preferable. Instead, the authors push for <a href="https://www.earth.com/news/forest-restoration-aids-humans-nature-climate-together/" target="_blank" rel="noreferrer noopener">forest restoration</a> as a top priority.



“I don’t know if it’s useful to think about continuous vs. fragmented landscapes. We need to protect biodiversity and I think this debate is not helping to actually support conservation,” he said. 



“In many, many countries there aren’t many large, intact forests remaining. Therefore, our focus should be on planting new forests and restoring increasingly degraded habitats. Restoration is crucial for the future, more so than debating whether it’s better to have one large forest or many smaller fragments.”



With many forest ecosystems already facing pressures- from <a href="https://www.earth.com/news/rainforests-replanted-seedlings-after-logging-do-not-recover-well/" target="_blank" rel="noreferrer noopener">logging</a> and agriculture to climate change - restoration may be the pivotal step to ensure that habitats regain some of their lost ecological complexity. 



By renewing expanses of continuous forest wherever possible, conservationists can maximize carbon storage while also supporting the wide variety of species needed for healthy, enduring ecosystems.

Large, undisturbed forests support greater biodiversity 

A recent investigation shows that large, unbroken forests support more...

Chocolate is a comfort food for many people and a symbol of happiness in countless cultures. For years, farmers and scientists have collaborated to refine this treasured <a href="https://www.earth.com/news/sustainable-farming-could-save-the-future-of-chocolate/" target="_blank" rel="noreferrer noopener">plant</a>, but new evidence shows there is more to its story than meets the eye.



Experts have been analyzing genetic details that trace the cacao tree’s past to a surprising point in time. <a href="https://www.researchgate.net/profile/Daniel-Tineo" target="_blank" rel="noreferrer noopener">Daniel Tineo</a>, from the National University Toribio Rodríguez de Mendoza, led a study that used chloroplast genome data to examine when and how Theobroma cacao diversified.



<h2 class="wp-block-heading" id="h-chocolate-s-place-in-nature">Chocolate’s place in nature</h2>



Cacao belongs to the Malvaceae family, which also includes hibiscus and cotton. This group of plants has a history going back millions of years, and reflecting a long process of <a href="https://www.earth.com/news/chocolate-and-cocoa-prices-have-doubled-in-the-past-year-climate-change/" target="_blank" rel="noreferrer noopener">adaptation</a> and survival.



“It can be inferred that T. cacao diverged at approximately 7.55 Ma, and it is highly likely that T. cacao populations diversified during the Pliocene or Miocene,” explained Tineo. 



Two main factors appear to have played a role in shaping the trees we see today. First, their <a href="https://www.sciencedirect.com/topics/agricultural-and-biological-sciences/chloroplast-genome" target="_blank" rel="noreferrer noopener">chloroplast genomes</a> carry signs of gradual change, which is common in species that extend across tropical regions. Second, environmental pressures likely promoted different genetic traits in various localities.



<h2 class="wp-block-heading" id="h-genetic-insights-to-save-chocolate">Genetic insights to save chocolate </h2>



The chloroplast genome, often called <a href="https://www.sciencedirect.com/topics/agricultural-and-biological-sciences/chloroplast-dna" target="_blank" rel="noreferrer noopener">cpDNA</a>, is inherited in a predictable way in most plants. This trait gives scientists a clear view of family relationships, even within the same species.



One gene, named <a href="https://www.nature.com/articles/srep08348" target="_blank" rel="noreferrer noopener">ycf1</a>, turned out to be important because it showed more differences among cacao plants than other commonly studied genetic regions. By examining these differences, researchers hope to spot unique traits that may improve the flavor, resilience, or productivity of <a href="https://www.earth.com/news/cocoa-production-in-africa-is-under-extreme-climate-pressure/" target="_blank" rel="noreferrer noopener">cacao varieties</a>.



This approach might help breeders develop trees that survive better in changing climates. It may also allow them to detect disease-resistant lines, thus cutting down on the need for chemical treatments and on farm losses.



<h2 class="wp-block-heading" id="h-why-the-past-matters">Why the past matters </h2>



Farmers today face pests, diseases, and market uncertainty. Learning about cacao’s ancient lineage is not just for academic interest; it can also guide solutions that reduce farming risks.



The deeper a plant’s genetic roots, the more variation it hides in its DNA. This variation supplies fresh building blocks for traits like drought tolerance, flavor, and disease resistance.



<h2 class="wp-block-heading" id="h-practical-benefits-for-farmers">Practical benefits for farmers</h2>



Thousands of smallholders grow cacao as a main or side income. When farmers tap into genetically diverse planting materials, their crops can adapt more effectively to different environments.



A broader gene pool also lowers the chance that a single disease outbreak will devastate cacao plants in an entire region. Strengthening genetic tools for farmers promotes stable harvests and consistently better beans.



<h2 class="wp-block-heading" id="h-modern-breeding-methods">Modern breeding methods</h2>



Classic breeding methods rely on observing which trees yield the best crops. Now, molecular tools add a scientific boost by marking the genes that truly matter.



When breeders target specific genes - like ycf1 - they can make more precise matches between strong, disease-tolerant varieties and those with desired flavors. This level of detail speeds up the long process of developing improved trees.



<h2 class="wp-block-heading" id="h-balancing-tradition-with-discovery">Balancing tradition with discovery</h2>



Farmers in Latin America, Africa, and Asia have nurtured cacao for generations. Their local expertise is valuable when it comes to spotting subtle differences among trees.



Collaboration between traditional growers and research institutions bridges technology and cultural wisdom. This approach promotes new partnerships that benefit everyone, from growers to chocolate enthusiasts.



<h2 class="wp-block-heading" id="h-protecting-the-future-of-chocolate">Protecting the future of chocolate </h2>



Scientists still do not fully understand how <a href="https://www.nature.com/articles/s41586-022-05288-7" target="_blank" rel="noreferrer noopener">nuclear or mitochondrial data</a> compare with chloroplast results. More work is needed to fill the gaps left by incomplete samples from various parts of the tropics.



Some lines may carry rare genetic elements waiting to be explored. Locating these hidden genes could reveal new ways to manage diseases and keep farms flourishing.



Cacao stands at a crossroads of heritage, commerce, and science. Studies suggest that this plant’s DNA is more varied and ancient than was once believed, hinting that there may be more secrets in its cells.



Ongoing research may answer questions about how different cacao types emerged and how they can be preserved. The bigger picture promises a future where growers and chocolate lovers share the rewards of knowledge-driven innovation.



The study is published in the journal <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0316148" target="_blank" rel="noreferrer noopener">PLOS One</a>.

Can chocolate survive? DNA research may help save cacao trees

Chocolate is a comfort food for many people and a...

Many of us enjoy a banana without a second thought, but new research suggests that rising global temperatures could make this simple pleasure harder to come by.



Researchers have determined that large parts of Latin America and the Caribbean could be unable to sustain banana <a href="https://www.earth.com/news/agroforestry-could-transform-farming-in-the-midwest/" target="_blank" rel="noreferrer noopener">production</a> for export by 2080. The study was led by <a href="https://experts.exeter.ac.uk/22744-dan-bebber" target="_blank" rel="noreferrer noopener">Dan Bebber</a> from the University of Exeter.



<h2 class="wp-block-heading" id="h-shifting-supply-landscape">Shifting supply landscape</h2>



Bananas are a key export crop worth $11 billion. They power the economies of many nations that rely on steady harvests and predictable trade relationships.



These recent projections show that climate change threatens about 60% of current growing regions. Economic setbacks and job losses in these areas could follow if swift action is not taken.



Producers face multiple uncertainties, from rising temperatures to unpredictable rainfall. Some farmers are already noticing shifts in planting schedules and increased difficulties in keeping fields <a href="https://www.earth.com/news/robotic-insects-may-be-the-future-of-farming-and-plant-pollination/" target="_blank" rel="noreferrer noopener">productive</a>.



Experts warn that these changes could create a chain reaction for global markets. This scenario is particularly concerning for people who depend on bananas for both nutrition and income.



Scientists note that shifting temperatures could also allow pests to flourish. This change puts more pressure on growers who have to adapt to new threats.



<h2 class="wp-block-heading" id="h-economic-ripple-effects">Economic ripple effects</h2>



Banana exports are a major source of revenue in certain countries. Without them, families and entire communities would be forced to seek new ways to earn a living.



Traders and distributors also stand to lose if volumes drop or if producers relocate to different areas. Businesses that rely on a consistent supply risk losing profit margins.



Transportation networks near ports highlight how reliant this industry is on accessible shipping. Any disruption in that setup could prolong delivery times and raise costs.



Analysts highlight that this fruit’s supply chain has always balanced on slim margins. A sudden climate-related shortfall can send waves across multiple markets.



Money for new technology often goes to bigger operations first. Smaller farms lack the resources to handle sudden shifts in weather or market demands.



<h2 class="wp-block-heading" id="h-rising-temperatures-hurt-bananas">Rising temperatures hurt bananas</h2>



Rising temperatures are a central factor behind banana production declines. Many varieties cannot thrive when daytime heat moves beyond their comfort zone.



Intense heat can reduce pollination and slow growth, forcing higher water usage and more stress on plants. Some farmers implement irrigation, but that introduces extra costs.



These difficulties have already prompted fears about productivity. Some areas might become completely unsuitable if average temperatures continue to climb.



Researchers have tied these temperature spikes to broader global warming <a href="https://www.ipcc.ch/report/ar6/wg1/" target="_blank" rel="noreferrer noopener">patterns</a>. They say more extreme heat events may appear if <a href="https://www.epa.gov/ghgemissions/sources-greenhouse-gas-emissions" target="_blank" rel="noreferrer noopener">greenhouse gas emissions</a> remain high.



Some producers explore shade-grown systems to reduce scorching, but this method can limit large-scale operations due to space and management <a href="https://www.earth.com/news/mixed-cover-crops-may-be-the-future-of-sustainable-farming/" target="_blank" rel="noreferrer noopener">requirements</a>.



<h2 class="wp-block-heading" id="h-socioeconomic-stumbling-blocks">Socioeconomic stumbling blocks</h2>



Adaptation is not simply a matter of finding new farmland. Many plantations are located in densely populated areas where labor is available.



Moving operations to less populated zones sounds logical, but shipping routes and basic infrastructure remain essential. Building new roads and port facilities is no small feat.



Limited finances often block these developments. Wealthier regions might upgrade quickly, while smaller producers struggle to keep up.



Efforts like training programs could help, but they require financial backing and stable governance. Local workers also need assurance of fair pay and good working conditions.



Community-based projects might ease tensions over land use. These initiatives can support shared resources, but they hinge on cooperative planning.



<h2 class="wp-block-heading" id="h-bananas-adapting-to-temperature-shifts">Bananas adapting to temperature shifts</h2>



One approach involves breeding heat-tolerant bananas. This strategy aims to keep yields stable even in warmer climates.



Irrigation systems play a key role in mitigating dryness. Some regions have turned to drip irrigation and water-saving technology, but these solutions often come with a hefty price tag.



Experts emphasize the importance of preventing disease outbreaks as well. Emerging pathogens can strike when crops are stressed by temperature swings or water scarcity.



“Our findings are a stark reminder that climate change is not just an environmental issue but a direct threat to global food security and livelihoods. Bananas are one of the world's most important fruits, not only for consumers but for millions of workers in producing countries,” said Bebber.



Combining traditional knowledge with modern science could offer practical responses that keep bananas viable in rising temperatures.



Local governments may encourage water management training. This approach helps people learn efficient techniques that preserve scarce resources.



<h2 class="wp-block-heading" id="h-sustainable-farming-and-funding">Sustainable farming and funding</h2>



Some research groups partner with communities to test pilot projects on sustainable <a href="https://www.earth.com/news/disease-resistant-banana-may-change-the-future-of-farming/" target="_blank" rel="noreferrer noopener">farming</a>. The results often show that early planning can ward off major disruptions.



Industry groups are focusing on ways to preserve farmland while cutting emissions. Some growers explore renewable energy options to power equipment.



Alternative financing, such as <a href="https://www.sba.gov/funding-programs/loans/microloans" target="_blank" rel="noreferrer noopener">microloans</a>, can help farmers upgrade equipment. This step ensures that no one is left behind.



The study is published in the journal <a href="https://www.nature.com/articles/s43016-025-01130-1" target="_blank" rel="noreferrer noopener">Nature Food</a>.

Rising temperatures threaten the future of banana farming

Many of us enjoy a banana without a second thought,...

Earth's climate is changing fast, and scientists are racing to understand how plants will respond. As temperatures rise and carbon dioxide levels increase, plants face new challenges and opportunities.



Some may grow larger, while others might struggle to maintain their natural processes. Understanding these shifts is essential for predicting future agricultural yields and ecosystem stability.



Researchers at the MSU-DOE Plant Research Laboratory (<a href="https://prl.natsci.msu.edu" target="_blank" rel="noreferrer noopener">PRL</a>) Sharkey lab are studying how plant metabolism reacts to high light and high CO2 (HLHC) conditions.



The findings reveal that plants photosynthesize more in these conditions, which can result in larger <a href="https://www.earth.com/news/plants-may-stop-absorbing-carbon-if-temperatures-continue-to-rise/" target="_blank" rel="noreferrer noopener">plants</a> and higher crop yields. However, this process comes with a cost - plants also lose carbon, a key component for making food.



These results, published in Scientific Reports, highlight the complexity of plant responses to environmental changes.



<h2 class="wp-block-heading" id="h-the-future-of-plant-metabolism">The future of plant metabolism </h2>



Scientists predict two major environmental shifts will affect plant metabolism. First, atmospheric carbon dioxide levels will continue rising. 



Second, global brightening will alter light conditions, as more solar radiation reaches the Earth's surface than in previous decades.



These <a href="https://www.earth.com/news/natures-climate-solutions-mixed-forests-store-more-carbon/" target="_blank" rel="noreferrer noopener">shifts</a> will impact how plants grow and process carbon. Understanding these effects is crucial for future agricultural and ecological planning.



<h2 class="wp-block-heading" id="h-increasing-photosynthesis-rates">Increasing photosynthesis rates</h2>



“Our work demonstrates that it’s very important to study photosynthesis and the carbon metabolism in plants,” said Yuan Xu, postdoctoral researcher in the <a href="https://bmb.natsci.msu.edu/labs/sharkey-lab/sharkey-lab.aspx" target="_blank" rel="noreferrer noopener">Sharkey lab</a> and first author of the study. 



“Especially when we think about conditions for the future based on predictions. If you want to do bioengineering in the future, to make a plant that can better adapt to these future conditions, you need to focus on these areas.”



The experts found that in future conditions, photosynthesis rates increase, but light respiration rates remain unchanged. This means plants can produce more sucrose and starch, which are vital for their survival and growth.



<h2 class="wp-block-heading" id="h-how-plants-store-carbon">How plants store carbon</h2>



“Most carbon fixed in photosynthesis becomes either starch [to use later] – like putting money in your bank account – or sucrose (table sugar) to use now – like buying an ice cream cone,” said Thomas D. Sharkey, University Distinguished Professor in the PRL. 



“The most surprising observation was that extra carbon at high light and high carbon dioxide went much more to starch (76% increase) rather than sucrose (41% increase). This may help plants become more resilient because they will have extra carbon for growth or defense.”



Larger plants and increased crop yields could result from this higher rate of photosynthesis. However, a challenge remains: plants also lose carbon during the <a href="https://www.earth.com/news/plants-absorb-31-more-co2-than-previously-estimated/" target="_blank" rel="noreferrer noopener">process</a>, reducing the total available food.



<h2 class="wp-block-heading" id="h-resilience-of-future-plants">Resilience of future plants</h2>



During photosynthesis, plants release CO2 through a process called respiration in light (RL). 



The researchers found that RL remains constant under both current and future conditions. Despite increased photosynthesis, the rate at which plants release CO2 through RL does not change.



This suggests that while plants may grow larger, they still lose a steady amount of carbon. Understanding this balance is essential for improving plant resilience in changing environments.



<h2 class="wp-block-heading" id="h-measuring-plant-carbon-loss">Measuring plant carbon loss</h2>



To analyze RL under HLHC conditions, researchers used a unique approach. Traditional methods like the Laisk or Kok techniques only work in low light <a href="https://www.earth.com/news/earths-carbon-sinks-are-being-pushed-to-their-limits/" target="_blank" rel="noreferrer noopener">conditions</a>.



“That’s why this study is unique,” Xu explained. “We used a new approach to measure the RL in the high light condition that cannot be measured using the old method.”



Xu applied a technique known as isotopically nonstationary metabolic flux analysis (INST-MFA). This method, commonly used in bacteria and fungi studies, has rarely been applied to <a href="https://www.earth.com/news/planting-diverse-crops-traps-carbon-and-boosts-soil-health/" target="_blank" rel="noreferrer noopener">plant research</a>.



<h2 class="wp-block-heading" id="h-future-research-directions">Future research directions</h2>



The Sharkey lab plans to continue exploring respiration in light using advanced research techniques. Their goal is to deepen the understanding of how plants take in and release carbon dioxide.



“We know from this study that many things are changed [under future conditions] including photosynthesis, photorespiration and respiration in the light,” Xu said. “This gave a hint for future work.”



The research was funded by the Division of Chemical Sciences, Geosciences, and Biosciences, Office of Basic Energy Sciences at the U.S. Department of Energy. 



The study is published in the journal <a href="https://www.nature.com/articles/s41598-025-88574-4" target="_blank" rel="noreferrer noopener">Scientific Reports</a>.

How future climate conditions will transform plant growth

Earth's climate is changing fast, and scientists are racing to...

The end-Permian mass extinction, 252 million years ago, was devastating to life on Earth. Massive volcanic eruptions unleashed 100,000 billion metric tons of carbon dioxide, triggering a severe climate crisis.



This led to extreme global warming, deoxygenated oceans, and widespread extinction. However, many plants survived, leaving fossil records that help scientists understand a dramatic 10-degree rise in <a href="https://www.earth.com/news/scientists-predict-how-and-when-humans-and-mammals-will-face-extinction/" target="_blank" rel="noreferrer noopener">global temperatures</a>.



“While fossilized spores and pollen of plants from the Early Triassic do not provide strong evidence for a sudden and catastrophic biodiversity loss, both marine and terrestrial animals experienced the most severe mass extinction in Earth’s history,” explained Dr. Maura Brunetti of the <a href="https://www.unige.ch/en/" target="_blank" rel="noreferrer noopener">University of Geneva</a>. 



“Life on Earth had to adjust to repeated changes in climate and the carbon cycle for several million years after the Permian-Triassic Boundary.”



<h2 class="wp-block-heading" id="h-reconstructing-the-ancient-climate">Reconstructing the ancient climate</h2>



The scientists studied five geological stages on either side of the Permian-Triassic Boundary. These included the Permian Wuchiapingian and Changhsingian, the early Triassic Induan and Olenekian, and the middle Triassic Anisian.



Using maps of Earth’s ancient geography and plant fossil data, the researchers identified six major biomes and estimated local climates based on fossil distributions.



The identified biomes ranged from tropical, humid regions to seasonal temperate and desert areas. 



Cold climates featured desert in the tropics and tundra at higher latitudes, while warm <a href="https://www.earth.com/news/public-concern-over-species-extinctions-fades-quickly/" target="_blank" rel="noreferrer noopener">climates</a> had temperate vegetation near the poles and deserts near the equator. Increased carbon dioxide levels led to warmer and wetter conditions.



<h2 class="wp-block-heading" id="h-climate-and-ecosystem-shifts-after-extinction">Climate and ecosystem shifts after extinction</h2>



Using statistical models, the scientists compared plant fossil records with simulated biomes under different climate conditions. Their findings revealed dramatic shifts in ecosystems at the Permian-Triassic Boundary.



Before the extinction, the Permian had a colder climate. The early Triassic Induan period showed <a href="https://www.earth.com/news/how-forests-rose-again-after-the-planets-most-extreme-extinction/" target="_blank" rel="noreferrer noopener">unstable conditions</a> that scientists could not clearly classify. 



This uncertainty may be due to sampling biases, poor fossil preservation, or short-term climate variations. More fossil data is needed for clarity.



Later Triassic periods saw significantly warmer conditions. The Olenekian and Anisian stabilized at temperatures 10 degrees higher than the Permian.



<h2 class="wp-block-heading" id="h-a-hotter-future">A hotter future</h2>



“This transition from the colder climatic state to the hotter state is marked by an increase of approximately 10⁰C in the mean global surface air <a href="https://www.earth.com/news/half-of-the-worlds-heliconia-species-are-at-risk-of-extinction/" target="_blank" rel="noreferrer noopener">temperature</a> and an intensification of the water cycle,” said Dr. Brunetti.



“Tropical everwet and summerwet biomes emerged in the tropics, replacing predominantly desertic landscapes. Meanwhile, the warm-cool temperate biome shifted towards polar regions, leading to the complete disappearance of tundra ecosystems.”



Dr. Brunetti noted that the shift in vegetation cover can be linked to tipping mechanisms between climatic steady states, providing a potential framework for understanding the transition between Permian and Triassic.



“This framework can be used to understand tipping behavior in the climate system in response to the present-day CO2 increase. If this increase continues at the same rate, we will reach the level of emissions that caused the Permian-Triassic mass extinction in around 2,700 years — a much faster timescale than the Permian-Triassic Boundary emissions.”



<h2 class="wp-block-heading" id="h-uncertainties-and-future-research">Uncertainties and future research</h2>



More data and refined models are necessary for clearer conclusions. “The comparison between simulated biomes and the dataset is influenced by uncertainties, arising from paleogeographic reconstructions and the classification of fossil assemblages into biomes,” said Dr. Brunetti.



“Furthermore, our climate modeling setup relies on offline coupling between models — the vegetation model uses the final outputs of the climatic model for biome reconstruction. This could be enhanced using a dynamic vegetation model.”



The Permian-Triassic extinction reshaped life on <a href="https://www.earth.com/news/saving-earths-most-endangered-plants-from-extinction-proving-difficult-botanic-gardens/" target="_blank" rel="noreferrer noopener">Earth</a>. Studying its causes and consequences may provide valuable insights into the ongoing climate crisis.



<h2 class="wp-block-heading" id="h-climate-lessons-from-past-extinctions">Climate lessons from past extinctions</h2>



The Permian-Triassic extinction reshaped the planet, erasing entire ecosystems and paving the way for new ones. 



By studying how life responded to these changes, scientists can better predict how today’s ecosystems will react to rising temperatures and shifting climate patterns.



Understanding the past is crucial for preparing for the future. If history is any indication, life on Earth will survive - but whether human civilization can adapt as effectively remains an open question.

Climate chaos: The mass extinction that reshaped life on Earth

The end-Permian mass extinction, 252 million years ago, was devastating...

Protecting wildlife while managing forests has always been a challenge. In California’s Sierra Nevada mountains, forest managers face difficult decisions as they try to prevent destructive wildfires without harming the birds and other species that call these forests home.



Traditional monitoring methods require significant time and effort, making it hard to collect enough data to guide <a href="https://www.earth.com/news/tropical-forests-are-struggling-to-keep-pace-with-climate-change/" target="_blank" rel="noreferrer noopener">conservation efforts</a>.



Now, scientists have introduced a breakthrough solution. Using thousands of microphones and advanced machine learning, researchers have developed a way to track forest birds over vast landscapes.



This innovative approach offers an unprecedented level of detail, providing valuable insights that help balance conservation with <a href="https://www.earth.com/news/dead-wood-removal-can-save-forests-from-future-wildfires/" target="_blank" rel="noreferrer noopener">forest</a> management. 



A new study highlights how bioacoustic technology can revolutionize wildlife monitoring and support better decision-making for the future of these forests.



<h2 class="wp-block-heading" id="h-capturing-bird-sounds">Capturing bird sounds </h2>



Researchers at the Cornell Lab of Ornithology’s K. Lisa Yang Center for Conservation Bioacoustics led this study, which analyzed more than 700,000 hours of bird sounds. 



The team deployed microphones at 1,600 sites, covering around six million acres of <a href="https://www.earth.com/news/how-forests-rose-again-after-the-planets-most-extreme-extinction/" target="_blank" rel="noreferrer noopener">forest</a>. The goal was to track ten important bird species, including owls and woodpeckers, which serve as indicators of forest health.



These species provide crucial information about changes in the environment. By listening to their calls across different locations, scientists can assess how forest conditions impact wildlife.



"The amount of coverage that gives us and the idea of what's happening with species at so many different locations allow for really powerful inference to be drawn from the network," said study lead author Kristin Brunk.



<h2 class="wp-block-heading" id="h-machine-learning-and-wildlife-monitoring">Machine learning and wildlife monitoring</h2>



To analyze the massive amount of recorded data, scientists turned to BirdNET, a machine-learning algorithm designed to identify bird calls automatically. This system allows researchers to recognize different species and understand how their presence relates to <a href="https://www.earth.com/news/natures-climate-solutions-mixed-forests-store-more-carbon/" target="_blank" rel="noreferrer noopener">environmental conditions</a>.



The study examined how factors such as tree density and canopy cover influence bird populations. These are the same variables that forest managers consider when making conservation decisions. The ability to connect bird activity with habitat conditions provides an essential tool for guiding land management strategies.



By mapping where different birds live, researchers can help forest managers make more informed choices. This is especially important as they work to reduce wildfire risks through controlled burns and forest thinning. Without careful planning, these activities could unintentionally disrupt bird populations.



"We're able to understand bird populations in the context of the forest conditions that are going to be actively manipulated by the management community to hopefully restore some resilience to this system," said Connor Wood, lead researcher at the <a href="https://www.birds.cornell.edu/ccb/" target="_blank" rel="noreferrer noopener">K. Lisa Yang Center for Conservation Bioacoustics</a>.



<h2 class="wp-block-heading" id="h-cheaper-forest-bird-tracking">Cheaper forest bird tracking</h2>



Monitoring wildlife over such a large area would be nearly impossible using traditional methods. Conducting field surveys requires a significant investment of time and resources. In contrast, passive acoustic monitoring offers a more efficient and cost-effective solution.



"If you think about what the cost would have been to get that amount of information by having biologists collecting data across the landscape… the cost effectiveness can't really be matched," Brunk noted.



This system enables continuous, long-term monitoring without the need for large field teams. The data collected can also be used to track changes in bird populations over time, offering a deeper understanding of how forests evolve under different management strategies.



<h2 class="wp-block-heading" id="h-forest-bird-monitoring">Forest bird monitoring </h2>



The success of this study goes beyond California’s Sierra Nevada. The researchers believe that bioacoustic monitoring can be applied to other regions facing similar conservation challenges. 



By adapting this technology, scientists and <a href="https://www.earth.com/news/future-forests-which-tree-species-can-survive-climate-change/" target="_blank" rel="noreferrer noopener">forest</a> managers worldwide can gain better insights into wildlife populations and habitat conditions.



"It's sort of a blueprint for how passive acoustic monitoring can inform management," said Brunk.



This approach is particularly valuable in areas where human access is difficult. Remote forests, protected reserves, and even urban green spaces could benefit from passive monitoring. 



The ability to gather large amounts of data with minimal human disturbance makes this a promising tool for conservation efforts around the world.



<h2 class="wp-block-heading" id="h-future-of-forest-and-wildlife-protection">Future of forest and wildlife protection</h2>



The integration of cutting-edge technology with conservation practices represents a major step forward. Listening to the sounds of the forest can help scientists understand how bird populations respond to changes in their <a href="https://www.earth.com/news/forests-are-still-fighting-climate-change-against-all-odds/" target="_blank" rel="noreferrer noopener">environment</a>.



"By combining new technologies with practical management needs, we're creating tools that can help protect both forests and wildlife during a time of rapid environmental change," said Wood.



The research was conducted in collaboration with the U.S. Forest Service, University of Wisconsin-Madison, Oregon State University, University of California-Merced, and Chemnitz University of Technology. This partnership highlights the increasing role of technology in conservation.



The study is published in the journal <a href="https://esajournals.onlinelibrary.wiley.com/doi/abs/10.1002/fee.2843" target="_blank" rel="noreferrer noopener">Frontiers in Ecology and the Environment</a>.

Every bird song can help scientists make smarter forest decisions

Protecting wildlife while managing forests has always been a challenge....

Selection,Of,Animal,And,Plant,Protein,Sources,-,Fish,,Meat,

Nearly 90% of adults in the United States believe they must eat meat, dairy, or eggs to get enough protein. This finding comes from a poll of 2,203 people who were surveyed in January 2025, and it highlights the lingering confusion around animal protein and plant-based eating.



Women and Gen Z participants were most likely to push back against the idea that animal products are required for <a href="https://www.earth.com/news/hemp-seeds-could-be-a-game-changer-as-an-alternative-protein-source/" target="_blank" rel="noreferrer noopener">adequate nutrition</a>. 



<a href="https://www.pcrm.org/about-us/staff/roxanne-becker" target="_blank" rel="noreferrer noopener">Dr. Roxanne Becker</a>, MBChB, DipIBLM, who is with the Physicians Committee for Responsible Medicine, <a href="https://www.pcrm.org/news/news-releases/nearly-90-us-adults-believe-inaccurately-its-important-eat-animal-products-get" target="_blank" rel="noreferrer noopener">notes</a> that some consumers still struggle to see how plant foods can match traditional protein sources.



<h2 class="wp-block-heading" id="h-can-plant-protein-replace-animal-protein">Can plant protein replace animal protein?</h2>



Consumers may worry about protein quality when moving away from animal <a href="https://www.earth.com/news/eating-more-plant-protein-lowers-the-risk-of-heart-disease/" target="_blank" rel="noreferrer noopener">foods</a>. One key concern is about whether plant proteins are too low in essential amino acids.



Plant-based proteins are often linked with health perks such as high fiber and reduced levels of unhealthy fats. 



They also contain a variety of vitamins and minerals that animal products may lack, but the question about adequate essential amino acids remains.



<h2 class="wp-block-heading" id="h-plant-protein-vs-animal-protein">Plant protein vs. animal protein</h2>



“Plant protein has been shown in randomized controlled trials to be as effective as animal protein for building muscle when the amounts of protein are equal. And it is full of nutrients and fiber, unlike animal-based protein sources,” clarified Dr. Becker.



There is strong support from <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC10537483/" target="_blank" rel="noreferrer noopener">controlled trials</a> for the benefits of plant-based eating.&nbsp;



In one <a href="https://pubmed.ncbi.nlm.nih.gov/33599941/" target="_blank" rel="noreferrer noopener">study</a>, men who followed a plant-based dietary plan or an omnivorous plan experienced similar gains in muscle mass when the diet was paired with resistance training. 



Similar protein amounts produced comparable results, regardless of the protein source. 



<h2 class="wp-block-heading" id="h-plant-protein-supports-better-aging">Plant protein supports better aging</h2>



Midlife nutrition habits can set the stage for quality of life decades later. An <a href="https://ajcn.nutrition.org/article/S0002-9165(23)66282-3/fulltext#tbl2" target="_blank" rel="noreferrer noopener">investigation</a> led by researchers from Harvard T.H. Chan School of Public Health (<a href="https://hsph.harvard.edu/" target="_blank" rel="noreferrer noopener">HSPH</a>) suggests that higher intake of plant protein in midlife may support healthy aging in women.



Participants in that study showed better physical and cognitive outcomes over the years when they relied on beans, nuts, and other plant-based staples. 



The findings indicate that animal protein may have a few benefits for mobility, but plant protein aligns with improved overall well-being.&nbsp;



<h2 class="wp-block-heading" id="h-practical-protein-needs">Practical protein needs</h2>



The minimum daily requirement for an adult is 0.8 grams of protein per kilogram (0.01 ounces per pound) of body weight. 



That’s about 56 grams for a 70-kilogram (2 ounces for a 155-pound) man and 46 grams for a 58-kilogram (1.6 ounces for a 128-pound) woman.



Those who exercise heavily may need up to 2 grams per kilogram (0.07 ounces per pound), especially if they’re doing strength training. 



Keeping track of these figures can guide individuals toward balanced dietary choices that nourish muscle growth and support overall health.



<h2 class="wp-block-heading" id="h-maintaining-muscle-with-age">Maintaining muscle with age</h2>



“As we age, it’s important to consume enough protein to maintain our muscle mass so we can avoid frailty. Plant protein sources, which contain no artery-clogging cholesterol and are low in saturated fat, should be the go-to,” said Dr. Becker. 



Older adults might lose muscle mass over time, so feeding the body with enough protein is wise.&nbsp;



Many plant-based options are naturally free of animal fats, which can help with <a href="https://www.ahajournals.org/doi/10.1161/JAHA.117.006659" target="_blank" rel="noreferrer noopener">heart health</a> in the long run. These foods are also linked to lower cholesterol levels.&nbsp;



<h2 class="wp-block-heading" id="h-ways-to-replace-animal-protein">Ways to replace animal protein</h2>



Busy schedules might make it tricky for some people to figure out a <a href="https://www.earth.com/news/futuristic-food-supply-transforming-co2-into-protein/" target="_blank" rel="noreferrer noopener">plant-friendly</a> menu that supplies adequate protein. 



Tofu, beans, lentils, peas, nuts and tempeh are familiar to many who want to load up on muscle-building nutrients without relying on animal <a href="https://www.earth.com/news/animals-are-suffering-from-declining-plant-quality/" target="_blank" rel="noreferrer noopener">products</a>.



“Unlike animal-based protein, these foods contain zero cholesterol and tend to be low in saturated fat, making them a smart choice for long-term health. Getting enough protein is as easy as enjoying meals you already know and love,” said Xavier Toledo, a registered dietitian with the Physicians Committee.



<h2 class="wp-block-heading" id="h-wider-acceptance">Wider acceptance</h2>



The survey revealed that more than half of respondents felt it was possible to gain muscle on a plant-based eating plan. 



This marks a change from older attitudes that portrayed animal <a href="https://www.earth.com/news/small-changes-in-diet-can-greatly-reduce-your-carbon-footprint/" target="_blank" rel="noreferrer noopener">protein</a> as the gold standard.



Despite strong acceptance among younger adults, the broader public still lags behind on the facts. That gap could close as research keeps highlighting the flexibility and benefits of plant-based <a href="https://www.earth.com/news/plant-based-meat-less-protein-lacks-certain-nutrients/" target="_blank" rel="noreferrer noopener">diets</a>.



The study is published in the <a href="https://ajcn.nutrition.org/article/S0002-9165(23)66282-3/" target="_blank" rel="noreferrer noopener">American Journal of Clinical Nutrition</a>.

Do humans need to eat animal protein to build muscle? Science has the answer

Nearly 90% of adults in the United States believe they...

The world is changing, and so is the climate. Sudden temperature drops, unexpected frosts, and shifting weather patterns challenge ecosystems in many ways. 



For plants, these changes are especially harsh. Unlike animals, they cannot migrate, seek shelter, or generate body heat in cold weather. Instead, they rely on internal <a href="https://www.earth.com/news/climate-warming-alters-plant-germination-and-disrupts-ecosystem-balance/" target="_blank" rel="noreferrer noopener">adaptations to survive</a>.



Varvara Dikaya at <a href="https://www.umu.se/en/" target="_blank" rel="noreferrer noopener">Umeå University</a> explored this challenge in her doctoral research. She studied a protein which plays a key role in plant adaptation to low temperatures.



The findings reveal that this protein participates in multiple signaling pathways, enabling plants to survive harsh conditions.



<h2 class="wp-block-heading" id="h-cold-response-strategies-of-plants">Cold response strategies of plants </h2>



Unlike animals, <a href="https://www.earth.com/news/shaded-plants-capture-light-beyond-the-visible-spectrum/" target="_blank" rel="noreferrer noopener">plants</a> cannot seek warmth or migrate. Their survival depends on internal mechanisms that adjust to temperature shifts. 



Past research focused on molecules like amino acids and sugars, which help prevent freezing. Scientists also studied core temperature-response mechanisms, but many crucial components remained unknown.



Dikaya’s <a href="http://umu.diva-portal.org/smash/record.jsf?pid=diva2:1933796" target="_blank" rel="noreferrer noopener">research</a> uncovers a missing piece of this puzzle - RNA splicing. This process determines which proteins are produced in plant cells, directly impacting cold response strategies.



<h2 class="wp-block-heading" id="h-understanding-rna-splicing-the-basics">Understanding RNA splicing - the basics</h2>



<a href="https://www.earth.com/news/human-cells-communicate-with-each-other-through-rna/" target="_blank" rel="noreferrer noopener">RNA</a> splicing is like an editing process for your genes, making sure your cells get the right instructions to build proteins. 



When a gene gets copied into RNA, it includes extra sections called introns that don’t actually code for anything useful. 



Before the <a href="https://www.earth.com/news/rna-world-unraveling-mysteries-life-origin/" target="_blank" rel="noreferrer noopener">RNA can do its job</a>, the cell cuts out these introns and stitches together the remaining pieces, called exons. 



This process turns a raw RNA transcript into a polished, ready-to-go messenger RNA (mRNA) that cells can use to make proteins.



Sometimes, cells splice RNA in different ways, mixing and matching exons to produce multiple proteins from the same gene. 



This alternative splicing is why our relatively small number of genes can make such a huge range of proteins. When splicing goes wrong, though, it can lead to diseases like cancer and genetic disorders.



<h2 class="wp-block-heading" id="h-the-role-of-splicing">The role of splicing </h2>



"Splicing acts as a central hub controlling the information flow from DNA to RNA, defining which proteins are synthesized from a certain gene," explained Dikaya, who is a doctoral student in the Department of Plant Physiology at Umeå University and <a href="https://www.upsc.se" target="_blank" rel="noreferrer noopener">Umeå Plant Science Center</a>.



Her research focused on PORCUPINE, a protein discovered when scientists observed that plants with a mutation in this gene became unusually cold-sensitive. The mutation's spiky shoot tips inspired the name.



<h2 class="wp-block-heading" id="h-impact-of-temperature-drops">Impact of temperature drops</h2>



"The PORCUPINE mutant appears normal under ambient temperature conditions but cannot develop properly in the case of even a mild temperature drop," the team noted.



"Already at 16 degrees, the mutant grows shorter roots with increased root hair density and much smaller rosettes than normal. This is very special,."



Dikaya’s work reveals that cold temperatures trigger an increase in PORCUPINE RNA in cells. This suggests that the plant produces more of this protein to cope with the stress. 



However, PORCUPINE is not just a passive responder. It actively participates in the spliceosome, a complex that processes RNA before it transforms into proteins.



<h2 class="wp-block-heading" id="h-key-player-in-rna-processing">Key player in RNA processing</h2>



PORCUPINE is not just a responder to cold; it is an active participant in RNA processing. 



This protein is part of the spliceosome, a complex molecular machine that modifies RNA before it is translated into proteins. Without proper RNA splicing, plants cannot produce the proteins they need to survive.



By studying PORCUPINE’s role in the spliceosome, Dikaya and her team discovered that it influences multiple genetic pathways. 



Some of these pathways control how plants sense and react to cold temperature shifts. Others regulate growth patterns that determine whether a <a href="https://www.earth.com/news/predicting-how-climate-change-will-alter-plant-growth-cycles/" target="_blank" rel="noreferrer noopener">plant</a> can withstand stress.



<h2 class="wp-block-heading" id="h-a-network-of-cold-responses">A network of cold responses</h2>



Dikaya and her colleagues identified several genes controlled by PORCUPINE, all of which influence how plants respond to temperature changes. Her research highlights how intricate these responses are, involving multiple overlapping pathways.



"Our findings show the complexity of the cold response in plants. It is important to understand all aspects and identify fundamental mechanisms that could be applied later on in a practical manner," Dikaya noted.



"Such knowledge will be essential to create more resilient <a href="https://www.earth.com/news/bioelectric-future-harnessing-the-natural-energy-of-plants/" target="_blank" rel="noreferrer noopener">plants</a> capable of withstanding environmental challenges in the future, even though it is still a long way to go."



Her work provides a deeper understanding of how plants adjust to fluctuating temperatures. This knowledge could pave the way for crops that can better withstand future climate uncertainties.



<h2 class="wp-block-heading" id="h-future-of-cold-resistant-plants">Future of cold-resistant plants</h2>



The challenges of climate change are not going away, and neither is the need for <a href="https://www.earth.com/news/phantom-nutrient-the-secret-force-that-fuels-plant-growth/" target="_blank" rel="noreferrer noopener">resilient crops</a>. 



If researchers can harness the knowledge gained from studies like Dikaya’s, they may be able to develop plant varieties that thrive despite temperature fluctuations.



Although there is still much to learn, this research brings us one step closer to understanding the intricate mechanisms that allow plants to survive. In the years ahead, discoveries like this could reshape agriculture and help ensure food security in a changing world.
