Andreas Zedrosser, Auteur ; Eva Bellemain, Auteur ; Pierre Taberlet, Auteur ; Jon E. Swenson, Auteur1. We studied male yearly reproductive success (YRS) and its determinants (phenotypic characteristics, age, population density) in two Scandinavian brown bear populations, using molecular techniques to determine paternity. 2. We found a signific[...]
