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 Lab-spun sponges form perfect scaffolds for growing skin cells to heal wounds
(via sciencedaily.com) Original source A new technique for electro-spinning sponges has allowed scientists to directly produce 3D scaffolds -- on which skin grafts could be grown from the patient's own skin.
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 Scientists can tell where a mouse is looking and located based on its neural activity
(via sciencedaily.com) Original source Researchers have paired a deep learning model with experimental data to 'decode' mouse neural activity. Using the method, they can accurately determine where a mouse is located within an open environment and which direction it is facing, just by looking at its neural firing patterns. Being able to decode neural activity could provide insight into the function and behavior of individual neurons or even entire brain regions.
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 High resolution techniques reveal clues in 3.5 billion-year-old biomass
(via sciencedaily.com) Original source To learn about the first organisms on our planet, researchers have to analyze the rocks of the early Earth. These can only be found in a few places on the surface of the Earth. The Pilbara Craton in Western Australia is one of these rare sites: there are rocks there that are around 3.5 billion years old containing traces of the microorganisms that lived at that time. A research team has now found new clues about the formation and composition of this ancient biomass, providing insights into the earliest ecosystems on Earth.
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 Butterfly and moth genomes mostly unchanged despite 250 million years of evolution
(via sciencedaily.com) Original source Comparison of over 200 high-quality butterfly and moth genomes reveals key insights into their biology, evolution and diversification over the last 250 million years, as well as clues for conservation.
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 An awkward family reunion: Sea monsters are our cousins
(via sciencedaily.com) Original source The sea lamprey, a 500-million-year-old animal with a sharp-toothed suction cup for a mouth, is the thing of nightmares. A new study discovered that the hindbrain -- the part of the brain controlling vital functions like blood pressure and heart rate -- of both sea lampreys and humans is built using an extraordinarily similar molecular and genetic toolkit.
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 Low oxygen in lakes may breathe new life into conservation efforts for water quality
(via sciencedaily.com) Original source An international team analyzed 656 lakes across five continents to provide empirical evidence supporting a long-held theory regarding low deep-water oxygen concentrations, or anoxia.
