Stable isotopes reveal diet shift from pre-extinction to reintroduced Przewalski’s horses

Abstract The Przewalski’s horse (Equus ferus przewalskii), the only remaining wild horse within the equid family, is one of only a handful of species worldwide that went extinct in the wild, was saved by captive breeding, and has been successfully returned to the wild. However, concerns remain that...
