1. 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 significant difference in male YRS between the study areas, with lower YRS in the south than in the north. 3. In general, older and larger males had higher YRS. Older males may be more experienced in competition for reproduction (male dominance). Large body size… CONTINUE READING
