The diet of Tasmanian devils may accelerate their decline
For the study, the researchers investigated the diets of devil populations across habitats of differing levels of disturbance, from cleared pasture to undisturbed rainforest. They did this by analysing chemical stamps called stable isotopes in whisker samples taken from Tasmanian devils in different environments.
As the California sea lion population got bigger, so did male sea lions
Animals tend to get smaller as their populations grow because of increased competition for food resources among members of the same species. That’s not what has happened with California sea lions, however, according to a new study led by scientists at UC Santa Cruz.

Elephant seals drift off to sleep while diving far below the ocean surface

Large numbers of European chimpanzees suffer from a lack of vitamin D, says new study
A new study has found that a large number of chimpanzees living in Europe suffer from inadequate vitamin D levels, and the widespread problem could have a major impact on their health.
Alligators exposed to PFAS show autoimmune effects
The research team, led by Scott Belcher, associate professor of biology at North Carolina State University, took blood samples and did health evaluations on 49 alligators living along the Cape Fear River between 2018 and 2019. They compared these results to a reference population of 26 alligators from Lake Waccamaw, located in the adjoining Lumber River basin.
