Published Multiple uses of tropical mosaic landscapes
(via sciencedaily.com) Original source Many landscapes in the tropics consist of a mosaic of different types of land use. How people make use of these different ecosystems, with their particular plant communities, was unclear until now. Researchers, many of them from Madagascar, have now investigated this. When considering biodiversity, forests often get the most attention. But this research shows that rural households use a wide range of plant species and services provided by many nearby ecosystem types.
Published Small-winged and lighter colored butterflies likely to be at greatest threat from climate change
(via sciencedaily.com) Small-winged and lighter colored butterflies likely to be at greatest threat from climate change. The family, wing length and wing colour of tropical butterflies all influence their ability to withstand rising temperatures, say ecologists. The researchers believe this could help identify species whose survival is under threat from climate change.
Published Alien invasion: Study reveals alarming economic costs of biological invasions to the European Union
(via sciencedaily.com) Original source Biological invasions are a major threat to ecosystems, biodiversity, and human well-being, resulting in ecosystem degradation and causing economic costs in the multi-trillions of euros globally. A study sheds light on the stark economic cost resulting from biological invasions in the European Union (EU).
Published Fungi blaze a trail to fireproof cladding
(via sciencedaily.com) Original source Scientists have shown it's possible to grow fungi in thin sheets that could be used for fire-retardant cladding or even a new kind of fungal fashion.
Published Using AI to save species from extinction cascades
(via sciencedaily.com) Original source Algorithms can predict what movies or songs you might like, but they can also predict which species a predator would most likely eat. Researchers have been using machine learning to identify species interactions, and can predict which species are most likely to go extinct, so that intervention can be planned before this happens.
Published Marine fossils are a reliable benchmark for degrading and collapsing ecosystems
(via sciencedaily.com) Original source Humans began altering environments long before records were kept of the things that lived in them, making it difficult for scientists to determine what healthy ecosystems should look like. Researchers show the recent fossil record preserves a reliable snapshot of marine environments as they existed before humans.
Published Caterpillar venom study reveals toxins borrowed from bacteria
(via sciencedaily.com) Original source Researchers have found toxins in the venom of asp caterpillars are completely different to anything they have seen before in insects. Toxins in the caterpillar venom punch holes in cells the same way as toxins produced by disease-causing bacteria such as E. coli and Salmonella. Venoms are rich sources of new molecules that could be developed into medicines of the future, pesticides, or used as scientific tools.
Published Addressing justice in wildfire risk management
(via sciencedaily.com) Original source The unequal distribution of wildfire risk in our society is influenced by various factors, such as social vulnerabilities and intersecting forms of inequality, including gender, age, ethnicity, or disability. A new article calls for more integrated and inclusive wildfire risk management approaches and proposes a novel framework mapping different justice aspects.
Published Forest can adapt to climate change, but not quickly enough
(via sciencedaily.com) Original source America's forests have a tough time in store for them. Climate change is increasing temperatures and decreasing moisture levels across the country, not a winning combination for trees.
Published Study reveals how a tall spruce develops defense against hungry weevils
(via sciencedaily.com) Original source A study has identified genes involved in development of stone cells -- rigid cells that can block a nibbling insect from eating budding branches of the Sitka spruce evergreen tree. The insect's attack has stunted the growth of these forest giants.
Published Three things to know: Climate change's impact on extreme-weather events
(via sciencedaily.com) Original source Researchers found that the effects of climate change on the intensity, frequency, and duration of extreme weather events, like wildfires, could lead to massive increases in all three.
Published Wildfire smoke downwind affects health, wealth, mortality
(via sciencedaily.com) Original source Smoke particulates from wildfires could cause between 4,000 and 9,000 premature deaths and cost between $36 to $82 billion per year in the United States, according to new research.
Published Climate change could lead to 'widespread chaos' for insect communities
(via sciencedaily.com) Original source New research explores how a warming world could impact ecosystems and derail the development of new species.
Published Completing genome of rusty patched bumble bee may offer new approach to saving endangered bee
(via sciencedaily.com) Original source A detailed, high-resolution map of the rusty patched bumble bee's genome has been released, offering new approaches for bringing the native pollinator back from the danger of extinction. Putting together the rusty patched bumble bee genome is part of the Beenome 100 project, a first-of-its-kind effort to create a library of high-quality, highly detailed genome maps of 100 or more diverse bee species found in the United States.
Published Researchers find high risk to amphibians if fungal pathogen invades North America
(via sciencedaily.com) Original source New research indicates the fungal pathogen Batrachochytrium salamandrivorans (Bsal) could be devastating to amphibian biodiversity if introduced to North America.
Published Plant remediation effects on petroleum contamination
(via sciencedaily.com) Original source Initial choices about fertilization and grass seeding could have a long-lasting effect on how plants and their associated microbes break down pollution in petroleum-contaminated soils.
Published Team finds reliable predictor of plant species persistence, coexistence
(via sciencedaily.com) Original source Ecological scientists have long sought ways to measure and predict how specific plant communities will fare over time. Which species in a diverse population will persist and coexist? Which will decline? What factors might contribute to continuing biodiversity? Researchers report on a new method for determining whether pairs or groups of plant species are likely to coexist over time.
Published Older trees accumulate more mutations than their younger counterparts
(via sciencedaily.com) Original source A study of the relationship between the growth rate of tropical trees and the frequency of genetic mutations they accumulate suggests that older, long-lived trees play a greater role in generating and maintaining genetic diversity than short-lived trees.
Published Saving moths may be just as important as saving the bees
(via sciencedaily.com) Original source Night-time pollinators such as moths may visit just as many plants as bees, and should also be the focus of conservation and protection efforts, a new study suggests.
Published Air quality stations have collected vast stores of DNA by accident, a potentially 'game-changing' discovery for tracking global biodiversity
(via sciencedaily.com) Original source The accelerating loss of biodiversity and increasing rate of species extinction is a major threat to ecosystems around the globe. And yet, quantifying those losses at a large scale hasn't been possible, in large part due to a lack of the required infrastructure. But a new study shows that a major source for such information already exists in the form of environmental DNA (eDNA), which has been inadvertently collected in filters by thousands of ambient air quality monitoring stations in countries around the world for decades.
