Published Creepy crawlies protect apples when flowers are planted on farms
(via sciencedaily.com) Original source Bugs including hoverflies, lacewings and ladybirds play an important role in keeping Britain's apples healthy, a new study has shown.
Published Extinctions could result as fish change foraging behavior in response to rising temperatures
(via sciencedaily.com) Original source Fish species respond to temperature increases by going after more readily available prey. Models suggest this behavior could lead to more extinctions.
Published Microbial comics: RNA as a common language, presented in extracellular speech-bubbles
(via sciencedaily.com) Original source Decoding the conversations between microbes of hypersaline environments reveals deep insights into the origins of complex life.
Published Scientists assemble a richer picture of the plight and resilience of the foothill yellow-legged frog
(via sciencedaily.com) Original source Up to only a few inches in length, with a lemon-hued belly, the foothill yellow-legged frog may seem unassuming. But its range once stretched from central Oregon to Baja California. In 2023, it was listed under the federal Endangered Species Act. Its rapidly decreasing range is due in part to a fungal pathogen called Batrachochytrium dendrobatidis, or Bd, that has devastated amphibians around the world.
Published Reforestation schemes are not enough to recover the carbon created by harvesting wood
(via sciencedaily.com) Original source Forests have a critical role to play in capturing and storing carbon from the Earth's atmosphere -- but some models exaggerate their carbon removal potential by almost three-fold, according to a leading professor of forest economics.
Published Birds and bee lessons as Pacific field trips also solve 'Michener's mystery'
(via sciencedaily.com) Original source Eight new Pacific bee species and new insights into Fijian bird behaviour on Viti Levu Island have been described in new scientific studies. The research highlights the potential for species discovery, ecological and conservation knowledge and cultural engagement from Asia-Pacific research collaborations.
Published Robots, monitoring and healthy ecosystems could halve pesticide use without hurting productivity
(via sciencedaily.com) Original source Smarter crop farming that combats weeds, insect pests and plant diseases by integrating modern technologies like AI-based monitoring, robotics, and next-generation biotechnology with healthy and resilient agricultural ecosystems.
Published Predatory fish use rapid color changes to coordinate attacks
(via sciencedaily.com) Original source Striped marlin are some of the fastest animals on the planet and one of the ocean's top predators. When hunting in groups, individual marlin will take turns attacking schools of prey fish one at a time. Now a new study helps to explain how they might coordinate this turn-taking style of attack on their prey to avoid injuring each other. The key, according to the new work, is rapid color changes.
Published Streams connected to groundwater show improved detoxification and microbial diversity
(via sciencedaily.com) Original source Streams with ample connections to shallow groundwater flow-paths have greater microbial diversity and are more effective at preventing toxic forms of metals -- often products of upstream mining -- from entering and being transported downstream.
Published Side effects of wide scale forestation could reduce carbon removal benefits by up to a third
(via sciencedaily.com) Original source The side effects of large-scale forestation initiatives could reduce the CO2 removal benefits by up to a third, a pioneering study has found.
Published Cooler, wetter parts of Pacific Northwest likely to see more fires, new simulations predict
(via sciencedaily.com) Original source Forests in the coolest, wettest parts of the western Pacific Northwest are likely to see the biggest increases in burn probability, fire size and number of blazes as the climate continues to get warmer and drier.
Published Carbon emissions from the destruction of mangrove forests predicted to increase by 50,000% by the end of the century
(via sciencedaily.com) Original source The annual rate of carbon emissions due to the degradation of carbon stocks in mangrove forests is predicted to rise by nearly 50,000% by the end of the century, according to a new study. Mangroves in regions such as southern India, southeastern China, Singapore and eastern Australia are particularly affected.
Published Stronger storms free more nutrients from mud flats
(via sciencedaily.com) Original source If storms become stronger in the future due to climate change, more nitrogen may be released from the bottom of coastal seas.
Published Modeling tree masting
(via sciencedaily.com) Original source The effects of a phenomenon called tree masting on ecosystems and food webs can be better understood thanks to new theoretical models validated by real world observations.
Published Utah's Bonneville Salt Flats has long been in flux
(via sciencedaily.com) Original source It has been long assumed that Utah's Bonneville Salt Flats was formed as its ancient namesake lake dried up 13,000 years ago. But new research has gutted that narrative, determining these crusts did not form until several thousand years after Lake Bonneville disappeared, which could have important implications for managing this feature that has been shrinking for decades to the dismay of the racing community and others who revere the saline pan 100 miles west of Salt Lake City. Relying on radiocarbon analysis of pollen found in salt cores, the study concludes the salt began accumulating between 5,400 and 3,500 years ago, demonstrating how this geological feature is not a permanent fixture on the landscape.
Published Does Russia stand to benefit from climate change?
(via sciencedaily.com) Original source There exists a narrative about climate change that says there are winners and losers -- with Russia being one of the countries that stand to benefit from its effects. In a new study, researchers found that Russia is suffering from a variety of climate change impacts and is ill-prepared to mitigate or adapt to those climate impacts. And, as the rest of the world transitions to renewable energy sources, Russia's fossil-fuel-dependent government is not willing or ready to make alternative plans for the country, changes that could potentially benefit the whole of their society.
Published Citizen science to mitigate the environmental crisis in the marine environment
(via sciencedaily.com) Original source Citizen science can help to improve conservation and management strategies for Mediterranean marine ecosystems, and to mitigate the impact of the environmental crisis.
Published Converting rainforest to plantation impacts food webs and biodiversity
(via sciencedaily.com) Original source Every day, new areas of rainforests are converted into plantations, drastically changing tropical biodiversity and the way the ecosystem functions. Yet, the current understanding of the consequences is fragmentary: previous studies tended to examine either biodiversity or the ecosystem. An international research team brings these threads together in this study. They analyzed organisms ranging from microscopic mites and earthworms in the soil, to beetles and birds in tree canopies, comparing tropical rainforest with rubber and oil palm plantations in Sumatra, Indonesia.
Published 'The future is fungal': New research finds that fungi that live in healthy plants are sensitive to climate change
(via sciencedaily.com) Original source Findings more than a decade in the making reveal a rich diversity of beneficial fungi living in boreal forest trees, with implications for the health of forests.
Published Science fiction meets reality: New technique to overcome obstructed views
(via sciencedaily.com) Original source Using a single photograph, researchers created an algorithm that computes highly accurate, full-color three-dimensional reconstructions of areas behind obstacles -- a concept that can not only help prevent car crashes, but help law enforcement experts in hostage situations, search-and-rescue and strategic military efforts.
