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 Iceman Ötzi: Dark skin, bald head, Anatolian ancestry
(via sciencedaily.com) Original source A research team has used advanced sequencing technology to analyze Ötzi's genome to obtain a more accurate picture of the Iceman's appearance and genetic origins.
Published 'Resurrecting' the legendary figure behind Count Dracula
(via sciencedaily.com) Original source Vlad III, known as Vlad the Impaler, was a 15th century prince and military leader who was so terrifying, he's thought to have inspired the creation of the literary vampire, Count Dracula. Now, a scientific examination of his letters is giving new insights into his health. Researchers say the results suggest that Vlad probably had skin and respiratory conditions and could have even cried literal tears of blood.
Published Fossil feces infested with parasites from over 200 million years ago
(via sciencedaily.com) Original source Fossilized feces preserve evidence of ancient parasites that infected an aquatic predator over 200 million years ago, according to a new study.
Published Drops of seawater contain traces of an ancient world
(via sciencedaily.com) Original source New research links chemical changes in seawater to volcanic activity and changes.
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 Whale-like filter-feeding discovered in prehistoric marine reptile
(via sciencedaily.com) Original source A remarkable new fossil from China reveals for the first time that a group of reptiles were already using whale-like filter feeding 250 million years ago.
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.
Published Researchers find evolutionary adaption in trout of Wyoming's Wind River Mountains
(via sciencedaily.com) Original source Scientists found that trout from lakes stocked decades ago in the Wind River Mountains have higher numbers of gill rakers, which are bony or cartilage structures in the gullets of fish that act as sieves to retain zooplankton and nourish the trout. The difference is likely a result of the trout adapting to the food sources of the once-fishless high-mountain lakes -- a change that has taken place in a relatively short period of time and at a rate that is generally consistent with the historic timing of stocking for each of the lakes.
Published 'Time-traveling' pathogens in melting permafrost pose likely risk to environment
(via sciencedaily.com) Original source Ancient pathogens that escape from melting permafrost have real potential to damage microbial communities and might potentially threaten human health, according to a new study.
Published New study reveals that tree species diversity increases spider density
(via sciencedaily.com) Original source The link between tree diversity and spider populations can help homeowners and other land managers better plan tree plantings to naturally mitigate the effects of climate change.
Published Global wildlife trade risks altering evolutionary history and ecosystem function, study suggests
(via sciencedaily.com) Original source Some of the world's most distinct and ancient animal species, which play crucial roles in our planet's ecosystems, are exploited for the wildlife trade across large parts of the world, according to new research.
Published Earlier and earlier high-Arctic spring replaced by 'extreme year-to-year variation'
(via sciencedaily.com) Original source About 15 years ago, researchers reported that the timing of spring in high-Arctic Greenland had advanced at some of the fastest rates of change ever seen anywhere in the world. But, according to new evidence, that earlier pattern has since been completely erased. Instead of coming earlier and earlier, it seems the timing of Arctic spring is now driven by tremendous climate variability with drastic differences from one year to the next.
