Modeling habitat suitability accounting for forest structure and dynamics: Apennine brown bear as case study
Apennines brown bears (Ursus arctos marsicanus; Altobello 1921), isolated from the other European bear populations for at least 1500 years, are critically endangered and confined to a restricted range (Abruzzo-Lazio-Molise National Park, PNALM, and surrounding areas) in Italy. In light of the persis...
