Published Idai vs. Impalas: New study shows in real-time what helps mammals survive a natural disaster
(via sciencedaily.com) Original source After a massive cyclone transformed the ecosystem of Gorongosa National Park, researchers studied the immediate and knock-on impacts to garner lessons for wildlife managers around the world.
Published Nature photographers posting to social media help with protecting biodiversity
(via sciencedaily.com) Original source Nature photographers posting to social media are helping improve biodiversity conservation mapping in South Asia, and the method could go global.
Published New study reveals huge potential for future waves of invasive species
(via sciencedaily.com) Original source Human trade and transport have led to the intentional and accidental introductions of non-native species outside of their natural range globally. These biological invasions can cause extinctions, cost trillions, and spread diseases. A study has investigated how many of these non-native species already exist worldwide and which species groups are particularly prone to become non-native.
Published Hydrogen fuel can be a competitive alternative to gasoline and diesel today
(via sciencedaily.com) Original source Energy researchers posit hydrogen fuel can potentially be a cost-competitive and environmentally friendly alternative to gasoline and diesel, and that supplying hydrogen for transportation in the greater Houston area can be profitable today.
Published Forget social distancing: House finches become more social when sick
(via sciencedaily.com) Original source Social distancing when sick has become second nature to many of us in the past few years, but some sick animals appear to take a different approach. A new study of house finches uncovered a surprising result. Unlike other social animals who passively or actively isolate themselves when sick, this gregarious backyard bird species gravitates toward healthy flock mates when they are sick, even more so than healthy birds do.
Published Plants that survived dinosaur extinction pulled nitrogen from air
(via sciencedaily.com) Original source Ancient cycad lineages that survived the extinction of the dinosaurs may have done so by relying on symbiotic bacteria in their roots to fix atmospheric nitrogen. The finding came from an effort to understand ancient atmospheres, but became an insight into plant evolution instead.
Published New scientific study reveals the crucial role of herbivorous fishes and sea urchins in restoring Caribbean coral reefs
(via sciencedaily.com) Original source A new study presents crucial findings on the feeding preferences of herbivorous fishes and the sea urchin Diadema antillarum in Little Cayman. The study sheds new light on the dynamics of these herbivores and their impact on the resilience of Caribbean coral reefs.
Published Previously unknown luminescence revealed in ten deep sea species and an order of sea cucumbers
(via sciencedaily.com) Original source Researchers present evidence of previously unknown luminosity in 10 deep-sea species, suggesting underestimated diversity. These new discoveries include a member of the order Molpadia, which was previously thought not to be luminescent. The authors stress the importance of considering the ecological role of bioluminesence and the need for conservation.
Published Forecasting microbiomes for sustainability and health
(via sciencedaily.com) Original source Microbial communities, or microbiomes, are essential for safeguarding human and environmental health through the most widely used biotechnological process on our planet: biological wastewater treatment. However, the process itself is subject to constant changes, difficult to sustain over long periods of time and emits significant amounts of greenhouse gases.
Published Ammonia fuel offers great benefits but demands careful action
(via sciencedaily.com) Original source Researchers have identified the potential environmental risks of using ammonia as a zero-carbon fuel in order to develop an engineering roadmap to a sustainable ammonia economy.
Published Naturally regrowing forests are helping to protect the remaining old forests in the Amazon
(via sciencedaily.com) Original source Secondary forests that have regrown naturally on land abandoned from agriculture are important in counteracting the effects of forest fragmentation across the Amazon basin, according to new findings.
Published Diverse forests hold huge carbon potential, as long as we cut emissions
(via sciencedaily.com) Original source New study estimates that natural forest recovery could capture approximately 226 Gigatonnes (Gt) of carbon, but only if we also reduce greenhouse gas emissions. Achieving these results requires community-driven efforts to conserve and restore biodiversity. In brief: Forests have the potential to capture 226 Gigatonnes (Gt) of carbon in areas where they would naturally exist. This forest potential can only be achieved alongside emissions cuts. Sixty-one percent of the forest potential can be achieved by protecting existing forests and allowing them to regrow to maturity. Thirty-nine percent can be achieved by reconnecting fragmented landscapes through community-driven ecosystem restoration and management. A natural diversity of species is needed to maximize the forest carbon potential.
Published Solar-powered device produces clean water and clean fuel at the same time
(via sciencedaily.com) Original source A floating, solar-powered device that can turn contaminated water or seawater into clean hydrogen fuel and purified water, anywhere in the world, has been developed by researchers.
Published A fifth of European Red List flora and fauna species may be at risk of extinction
(via sciencedaily.com) Original source A new analysis of 14,669 threatened species of plants and animals found in Europe reveals that about one fifth face the risk of extinction, and that agricultural land-use change poses a significant threat to these species.
Published Southern Alaska's national forests key to meeting climate, conservation goals
(via sciencedaily.com) Original source Analyses of U.S. national forests shows that increased protections for two Alaskan forests is a key to meeting climate and biodiversity goals.
Published Experts predict 'catastrophic ecosystem collapse' of UK forests within the next 50 years if action not taken
(via sciencedaily.com) Original source Experts predict 'catastrophic ecosystem collapse' of UK forests within the next 50 years if action not taken. Other threats to UK forests include competition with society for water, viral diseases, and extreme weather affecting forest management.
Published First evidence of how the Asian malaria mosquito is spreading drug-resistant malaria in Africa
(via sciencedaily.com) Original source Research has led to the discovery of the role played by the Asian malaria mosquito (Anopheles stephensi) in the spread of drug and diagnosis-resistant malaria in Africa. Malaria is caused by a parasite which is spread by the bite of blood-sucking mosquitoes. According to the WHO, there were an estimated 247 million cases of malaria worldwide in 2021 with over 600,000 deaths, mostly in Africa. Children under 5 accounted for about 80% of all malaria deaths in the region.
Published Device 'smells' seawater to discover, detect novel molecules
(via sciencedaily.com) Original source Under the ocean's surface, marine organisms are constantly releasing invisible molecules. Some of the chemical clues reveal which creatures are nearby, while others could be used someday as medications. Now, researchers report a proof-of-concept device that 'sniffs' seawater, trapping dissolved compounds for analyses. The team showed that the system could easily concentrate molecules that are present in underwater caves and holds promise for drug discovery in fragile ecosystems, including coral reefs.
Published 'Biodiversity time machine' provides insights into a century of loss
(via sciencedaily.com) Original source AI analysis shows pollution levels, extreme weather events and increasing temperatures devastates biodiversity in freshwater lakes.
Published City and highway lights threaten mountain lion habitats
