Scientific Reports - Hard-object feeding adaptations infer relative predator-prey size relationships in Devonian placoderms

Native Australian animals range from high-hopping kangaroos to fast-running emus—but clever little bettongs also have a special ability to find and eat the food they love.

Petaurus notatus (Krefft’s Glider), introduced to Tasmania in the 1830s, has been linked to bird predation. Using geometric morphometrics, we found that Ta

Knowing what an animal eats can help biologists find it – especially when a species is as elusive as this one.

The mechanical properties of dietary items are known to influence skull morphology, either through evolution or by phenotypic plasticity. Here, we investigated the impact of supplementary feeding of peanuts on the morphology of red squirrels (Sciurus ...
