Demographic side effects of selective hunting in ungulates and carnivores
Milner, Jos M.; Nilsen, Erlend Birkeland; Andreassen, Harry Peter (Peer reviewed; Journal article, 2007)Selective harvesting regimes are often implemented because age and sex classes contribute differently to population dynamics and hunters show preferences associated with body size and trophy value. We reviewed the ... -
