Assessment of Brown Bear\'s (Ursus arctos syriacus) Winter Habitat Using Geographically Weighted Regression and Generalized Linear Model in South of Iran
Winter dens are one of the important components of brown bear's (Ursus arctos syriacus) habitat, affecting their reproduction and survival. Therefore identification of factors affecting the habitat selection and suitable denning areas in the conservation of our largest carnivore is necessary. W...
