A rare colony of least terns, a threatened, federally protected seabird, landed on Deerfield Beach in March, when humans did not have access to the sand. This is the first…
“#Using neural-network soundscapes to protect natural environments” Credit: CC0 Public Domain A team of researchers from Imperial College London, the University of Sydney and Cornel University has found that it is possible to create a soundscape from noises in the natural environment using machine-learning algorithms. In their paper published in Proceedings of the National Academy…
“#Pine beetles successful no matter how far they roam—with devastating effects” Whether they travel only a few metres or tens of kilometres to a new host tree, female pine beetles use different strategies to find success—with major negative consequences for pine trees, according to new research by University of Alberta biologists.

“#Rare twin red-ruffed lemurs born at Singapore zoo” The twin red-ruffed lemurs are moved in a pet-carrier to a vet for check-up in this picture relased by Wildlife Reserves Singapore Twin red-ruffed lemurs have been born at Singapore zoo, officials said Thursday, a rare double delivery that is a boost for the endangered saucer-eyed primates….
“#Invasive hedgehogs and ferrets habituate to and categorize smells” A wild ferret, captured for this experiment and then released, investigates scent in a jar placed in its pen. Researchers used cameras to monitor the predators’ nightly activity. Ferrets hunt primarily rabbits, but will eat eggs or chicks if they find them. Credit: Grant Norbury To…
“#Urban bees: pollinator diversity and plant interactions in city green spaces” Pollinator photo compilation from experiment. Credit: B. Daniels et al, 2020 (PLOS ONE, CC BY) With the right mix of plants, urban green spaces can be a rich habitat to support diverse pollinators, according to a study published July 15, 2020 in the open-access…
“#Movements of tiger sharks at varying life stages tracked in Gulf of Mexico” A tracking study of 56 sharks provides a first look at how their patterns of movement across the Gulf of Mexico vary according to their sex, their life stage, and the season. Matthew Ajemian of Florida Atlantic University, U.S., and colleagues present…
“#Studying whales with high-tech tools” Credit: Stanford University Scanning the airwaves over Monterey Bay with a hand-held antenna, Stanford University researchers listen for blue whales—or, more precisely, they listen for the suction tags they’ve stuck on blue whales. The first beep sounds and the captain whips the boat on course, following the quickening signal to…
