Indiana bats and northern long-eared bats coexist in central Indiana, but the populations of these two imperiled species are falling. To better protect them, researchers wanted to understand how they differed in their prey and …
Typically, the more predators are on the landscape, the less prey are around. Bring in more wolves (Canis lupus), and you can expect elk (Cervus canadensis) numbers to fall. “It makes total sense,” said Liana …
Even though there are no are no management plans or harvest limits for bobcats in the Black Hills of South Dakota, researchers don’t know much about how the populations—particularly kittens—are doing. As a result, South …
As the climate warms in the Arctic—two to three times faster than in the rest of the world—polar bears are changing what they eat. By uncovering their diets, researchers found, they can learn about more …
Around Jackson Hole, Wyoming, people are changing the ways wolves prey on elk, sometimes acting as a shield for the prey against their predators. Ungulates, like elk, in the area are increasingly using human-dominated landscapes …
For a relatively common species, researchers don’t know much about the natural history of western spotted skunks in the Pacific Northwest. What landscapes do they prefer? What prey species do they eat? Researchers are presenting …
Losing their tails doesn’t stop geckos from being able to capture their prey. That’s good news for the reptiles, which need plenty of nutrients to regenerate their lost appendages. Past studies have shown that tailless …
Using Fitbit-like devices and sound recorders, researchers have found more information about the hunting behavior of a cryptic species that’s difficult to observe. Allyson Menzies was a PhD student at McGill University on a project …
All over the world, there are instances of snakes feeding on spiders, researchers found in a recent meta-analysis. In a study published in the Journal of Arachnology, a team of scientists found 319 instances of …
Narwhal tusks can tell researchers a lot about the marine mammals’ feeding habits and exposure to dangerous chemicals. “They’re kind of like tree rings,” said Jean-Pierre Desforges, a postdoctoral research fellow at McGill University. “As …
