The relationship between form and function of the carnivore mandible. [PDF]
Anat Rec (Hoboken)Abstract Dietary morphology diversified extensively in Carnivoraformes (living Carnivora and their stem relatives) during the Cenozoic (the last 66 million years) as they evolved to capture, handle, and process new animal and plant diets. We used 3D geometric morphometrics, mechanical advantage, and finite element analysis to test the evolutionary ...

Bite-DNA Shows Substantial Browsing on Willows (<i>Salix</i> spp.) by North American Bison in Yellowstone National Park. [PDF]
Ecol EvolRiparian willows in Yellowstone National Park are shaped by ungulate browsing, but species‐specific contributions remain unclear. Using bite‐DNA metabarcoding of browsed willow twigs across six northern range sites, we found that American bison were the most frequent browsers, exceeding elk and often mule deer.
