In 2019, on a small island in coastal South Carolina, biologists discovered an animal migration phenomenon that was difficult to believe. Nearly 20,000 whimbrel were stopping at Deveaux Bank along their migration north -- half the estimated eastern population of the declining shorebird.
A study by University of Rhode Island researchers using a seldom-used methodology turned up many more Eastern spadefoots, an endangered primitive frog, than they expected.
Fewer Atlantic mangrove fiddler crab embryos survived in a warmer, more acid environment mimicking conditions forecast for the end of this century. Given the important ecological role of this invertebrate in mangroves, the researchers warn of a potential cascade effect.
The concentration of potentially toxic metals is increasing in the population of the franciscana dolphin --a small cetacean, endemic from the Rio de la Plata and an endangered species-- according to a study led by a team of the Faculty of Biology and the Biodiversity Research Institute (IRBio), published in the journal Science of The Total Environment.
The intracellular purple sulfur bacterium "Candidatus Thiodictyon intracellulare" has lost the ability to oxidize sulfur and now supplies a ciliate with energy from photosynthesis / Youtube video available.
Early migrations of humans to the Americas from Siberia around 12,000 years ago have been traced using the bacteria they carried by an international team including scientists at the University of Warwick.
Honeybees bring back more than just nectar from their floral feasts and these microbes may help them survive turbulent times.
New paper provides framework for how scientists can leverage community-generated data to monitor global biodiversity change and realize the full potential of community science
Climate change exerts great pressure for change on species and biodiversity. A recent study conducted by the University of Helsinki and the Finnish Environment Institute indicates that the few moth and butterfly species (Lepidoptera) capable of adjusting to a changing climate by advancing their flight period and moving further north have fared the best in Finland. In contrast, roughly 40% of Lepidoptera species have not been able to respond in either way, seeing their populations decline.
Real-world data from Sleep Number® smart bed sleepers shows a potential model for predicting and tracking COVID-19 infection using sleep and biometric measures. Analysis of 18.2 million 360 smart bed sleep sessions finds heart rate variability differs with age, gender and day of the week.
