Impact of a recolonizing, cross-border carnivore population on ungulate harvest in Scandinavia
Predation from large carnivores and human harvest are the two main mortality factors afecting the dynamics of many ungulate populations. We examined long-term moose (Alces alces) harvest data from two countries that share cross-border populations of wolves (Canis lupus) and their main prey moose. We...

Predation from large carnivores and human harvest are the two main mortality factors afecting the dynamics of many ungulate populations.
