Reproductive success in reindeer males in a herd with varying sex ratio
Abstract In polygynous species, male reproductive success is often correlated with dominance status of individual males and sex ratio in the population. Reindeer, Rangifer tarandus , is a polygynous species, and here we compared the variation in male reproductive success and dominance status during...
