Minimal impact of spotted hyenas on livestock and endangered species in a prey‐rich ecosystem

open access: yesWildlife Biology, EarlyView.
The diet of large carnivores is of great interest to conservation managers, as it can reveal the extent of human–carnivore conflict and the impact of carnivores on species of high conservation priority. Metabarcoding of environmental DNA can identify species and is often more reliable than observational or morphological methods, particularly when it ...
