Published Coastal fisheries show surprising resilience to marine heat waves
(via sciencedaily.com) New research found that marine heat waves -- prolonged periods of unusually warm ocean temperatures -- haven't had a lasting effect on the fish communities that feed most of the world. The finding is in stark contrast to the devastating effects seen on other marine ecosystems cataloged by scientists after similar periods of warming, including widespread coral bleaching and harmful algal blooms.
Published Emphasizing the need for energy independence could change the views of climate deniers, study says
(via sciencedaily.com) Original source Emphasising the need for energy independence and environmental stewardship could help to change people’s minds about the climate crisis, a new study says.
Published Unveiling global warming's impact on daily precipitation with deep learning
(via sciencedaily.com) Original source A research team has conclusively demonstrated that global warming stands as primary driver behind the recent increase in heavy rainfall and heatwaves using deep learning convolutional neural network.
Published Can this forest survive? Predicting forest death or recovery after drought
(via sciencedaily.com) Original source New work could help forest managers predict which forests are most at risk from drought and which will survive.
Published Climate extremes hit stressed economies even harder
(via sciencedaily.com) Original source Economies already under stress respond more strongly to weather events like heat waves, river floods and tropical cyclones, a new study shows. A global economic crisis as during the Covid-19 pandemic strongly amplifies the price increases private households experience from the impacts of weather extremes, a team of researchers finds. The price impacts tripled in China, doubled in the United States and increased by a third in the European Union.
Published Extreme weather events linked to increased child marriage
(via sciencedaily.com) Original source Among the negative impacts of extreme weather events around the world is one that most people may not think of: an increase in child marriages.
Published Broken by bison, aspen saplings having a tough time in northern Yellowstone
(via sciencedaily.com) In northern Yellowstone National Park, saplings of quaking aspen, an ecologically important tree in the American West, are being broken by a historically large bison herd, affecting the comeback of aspen from decades of over-browsing by elk.
Published Researchers take aim at weather forecasters' biggest blindspot
(via sciencedaily.com) Original source Anyone who's been caught in an unexpected downpour knows that weather forecasting is an imperfect science. Now, researchers are taking aim at one of meteorologists' biggest blind spots: extremely short-term forecasts, or nowcasts, that predict what will happen in a given location over the next few minutes.
Published Soils forming on the branches of trees are an overlooked forest habitat
(via sciencedaily.com) A study on 'canopy soils' on old trees in Costa Rica shows they are important habitats and carbon stores that cannot easily be replaced.
Published National parks support wildlife inside and outside their borders
(via sciencedaily.com) Fresh research suggests that national parks enhance bird diversity inside their borders. Large parks also support higher diversity of both birds and mammals in nearby unprotected areas.
Published New modeling method helps to explain extreme heat waves
(via sciencedaily.com) Original source To prepare for extreme heat waves around the world -- particularly in places known for cool summers -- climate-simulation models that include a new computing concept may save tens of thousands of lives.
Published Ice-free preservation method holds promise to protect reefs
(via sciencedaily.com) An interdisciplinary team of researchers demonstrated that coral can be preserved through a new technique called isochoric vitrification. This process takes the selected coral fragments through the stages of cryopreservation and subsequent revival.
Published Deforestation limits nesting habitat for cavity-nesting birds
(via sciencedaily.com) A new study of cavity-nesting birds in Ecuador shows the influence of deforestation on their habitat and reproductive success. Nest boxes could help.
Published Researchers unearth a new process by which algae pass on nurtrients to their coral host
(via sciencedaily.com) Researchers have identified a new pathway by which sugar is released by symbiotic algae. This pathway involves the largely overlooked cell wall, showing that this structure not only protects the cell but plays an important role in symbiosis and carbon circulation in the ocean.
Published Tree mortality in the Black Forest on the rise -- climate change a key driver
(via sciencedaily.com) Original source Climate impacts such as dry, hot summers reduce the growth and increase the mortality of trees in the Black Forest because they negatively influence the climatic water balance, i.e., the difference between precipitation and potential evapotranspiration. That is the central finding of a long-term study of the influence of climate and climate change on trees in the Black Forest.
Published Biodiversity protects against invasions of non-native tree species
(via sciencedaily.com) Researchers combined human and ecological factors to analyze the global scale of non-native tree species invasions. Human activity in hotspots of global trade, such as maritime ports, is linked to an increased likelihood of non-native tree species invasions. However, a high diversity of native tree species can help to curb the intensity of such invasions.
Published Atmospheric circulation weakens following volcanic eruptions
(via sciencedaily.com) Original source An international team of scientists found that volcanic eruptions can cause the Pacific Walker Circulation to temporarily weaken, inducing El Niño-like conditions. The results provide important insights into how El Niño and La Niña events may change in the future.
Published Fire, disease threatening sanctuary plants for Australian wildlife
(via sciencedaily.com) Original source New research has revealed Australia's iconic grasstrees -- known as 'yaccas' -- play a critical role in protecting wildlife from deadly weather extremes, thereby ensuring their survival. But the grasses themselves are under threat due to back burning, clearing and disease.
Published Detecting a vast diversity of rainforest animals by swabbing their DNA from leaves
(via sciencedaily.com) Researchers demonstrate that a vast multitude of birds and mammals can be detected by simply swabbing the DNA left behind by animals from leaves. They showcased the power of this approach in an ecosystem that hosts a ton of wildlife and where detecting animals has historically proven extremely challenging -- the tropical rainforest.
Published Pollutants are important to biodiversity's role in spread of wildlife diseases
(via sciencedaily.com) Conventional wisdom among ecologists holds that the more species there are inhabiting an ecosystem, the less vulnerable any one species will be to a threat like a parasite. A new study of tadpoles illustrates how overlapping biological and environmental factors can complicate how we value protecting diverse animal communities. The researchers found that environmental pollutants like road salt influence whether increased biodiversity helps or hinders disease outbreaks in wildlife, which can complicate how we value protecting diverse animal communities.
