Sawfish face global extinction unless overfishing is curbed
Sawfish have disappeared from half of the world’s coastal waters and the distinctive shark-like rays face complete extinction due to overfishing, according to a new study by Simon Fraser University researchers, published in Science Advances . Sawfish, named after their…
Desexing cats before 4 months old can reduce the number of unwanted kittens
The global problem of unowned domestic cats, driven by the cats’ phenomenal reproductive success, carries significant economic, animal welfare and biodiversity costs. Big-data research led by an expert on veterinary medicine and infectious diseases at City University of Hong Kong…
Man-made borders threaten wildlife as climate changes
Walls and fences designed to secure national borders could make it difficult for almost 700 mammal species to adapt to climate change, according to new research. The study led by Durham University, UK, is the first to look at how…
SSRgenotyper: A new tool to digitally genotype simple sequence repeats
SSRgenotyper is a newly developed, free bioinformatic tool that allows researchers to digitally genotype sequenced populations using simple sequence repeats (SSRs), a task that previously required time-consuming lab-based methods. Reporting in a recent issue of Applications in Plant Sciences ,…
Mapping hotspots of undersized fish and crustaceans may aid sustainable fishing practices
A new study in Frontiers in Marine Science provides a first-of-its-kind evaluation of which regions of southern European seas are in the most need of fishing restrictions. These areas have persistently shown high numbers of undersized fish and crustaceans, which…

DNA-based technique allows researchers to determine age of living beluga whales in Alaska
NEWPORT, Ore. – Researchers can now determine the age and sex of living beluga whales in Alaska’s Cook Inlet thanks to a new DNA-based technique that uses information from small samples of skin tissue. Accurate age estimates are vital to…
In a desert seared by climate change, burrowers fare better than birds
As the Mojave Desert’s bird communities collapse, small mammals’ ability to escape the sun in underground burrows is helping to keep their populations stable
Biodiversity is its own catalyst — to a point
Study sheds light on how microbiomes might recover from biodiversity loss
Marmoset monkeys eavesdrop and understand conversations between other marmosets
Humans continuously observe and evaluate interactions between third parties to decide with whom to interact in the future. But it is difficult to measure what information animals gain when they eavesdrop on vocal interactions between conspecifics: If they do understand…
More mammals are being struck by aircraft each year
Investigators have published a global review of mammal strikes with aircraft, noting that events have been increasing by up to 68% annually. More mammals were struck during the landing phase of an aircraft’s rotation than any other phase, according to…
