Published Farms that create habitat key to food security and biodiversity
(via sciencedaily.com) Diversified farming is an important complement to forest protections for reversing tropical biodiversity declines.
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 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 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 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 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 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.
Published World's deepest coral calcification rates measured off Hawaiian Islands
(via sciencedaily.com) In the waters off the Hawaiian Islands, rates of calcification were measured in the deepest coral colonies.
Published Harnessing big data reveals birds' coexisting tactics
(via sciencedaily.com) Birds likely hold smart insights about coexisting in popular habitats -- especially as climate change looms. Scientists peel back layers of big data to tease out real-life answers.
Published Pause in recent coral recovery on much of Great Barrier Reef
(via sciencedaily.com) In-water monitoring shows hard coral cover across the Great Barrier Reef remains at similar levels to that recorded in 2022, with small decreases in the Northern, Central and Southern regions. AIMS' Annual Summary Report on Coral Reef Condition for 2022/23 found that while some reefs continued to recover, their increased hard coral cover was offset by coral loss on other reefs. Most reefs underwent little change in coral cover.
Published City-dwelling wildlife demonstrate 'urban trait syndrome'
(via sciencedaily.com) City life favors species that are adaptable and not too fussy about what they eat, among other characteristics. A worldwide consortium of scientists calls the resulting collection of traits an 'Urban Trait Syndrome.'
Published Bat activity lower at solar farm sites
(via sciencedaily.com) The activity level of six bat species was significantly reduced at solar farm sites, researchers have observed.
Published Study reveals successful strategies for removing invasive caimans from Florida Everglades
(via sciencedaily.com) A new study reveals how a succession of strategies can take control of an invasive species population.
Published In the treetops: Ecologist studies canopy soil abundance, chemistry
(via sciencedaily.com) Original source Ecologists examined the distribution patterns of canopy soils, and their soil properties, across Costa Rican forests. The researchers suggest canopy soil may store more carbon than previously thought. Consideration of the time needed for reforestation of system with tree canopies should include the time needed for canopy mat regrowth.
Published Scientists dig into wildfire predictions, long-term impacts
(via sciencedaily.com) Original source Wildfires are an ancient force shaping the environment, but they have grown in frequency, range and intensity in response to a changing climate. Scientists are working on several fronts to better understand and predict these events and what they mean for the carbon cycle and biodiversity.
Published Study analyzes nearshore California marine heatwaves and cold spells amid changing climate conditions
(via sciencedaily.com) Original source Human-caused climate change has also caused extreme ocean temperatures and conditions with detrimental impacts on marine ecosystems and ocean-related ecology. A new study explores ocean temperature data along California's Coast, finding that certain environmental conditions and the state of the ocean led to an enhanced risk for marine heatwaves and cold spells, conditions that scientists and environmental managers will need to monitor to preserve and protect vital ecosystems critical to the California ocean economy, known as the Blue Economy.
