Polar bears and wolves may get the glory, but small predators like weasels, foxes and their cousins play outsized ecological roles. And many of these species are declining fast.
The key to protecting wolverines around the world is to reduce trapping, minimize predator control pressures, and to protect and connect large blocks of intact habitat they need to survive.
Our study used innovative 3D scanning and engineering-inspired computer simulations to understand the evolution of the penis bone in some mammals.
With less snow on the ground, weasels that turn white for winter are easier prey for foxes and wolves.
