Territory size of wolves Canis lupus: linking local (Białowieża Primeval Forest, Poland) and Holarctic‐scale patterns
Factors affecting territory size in wolves Canis lupus were studied at 2 scales, the local population (Białowieża Primeval Forest (BPF), eastern Poland) and the geographic range of species (literature review from 14 localities in the Holarctic). Four packs of wolves were studied by radio‐tracking in...
