A multivariate analysis of phenotype and paternity in male harbor seals, Phoca vitulina, at Sable Island, Nova Scotia
Understanding the links between phenotype and reproductive success is critical to the study of the evolution of mating systems and life-history patterns. We examined the relationship between phenotype and mating success of male harbor seals ( Phoca vitulina concolour ) at Sable Island, Canada. Clust...

Understanding the links between phenotype and reproductive success is critical to the study of the evolution of mating systems and life-history patterns. We examined the relationship between phenotype and mating success of male harbor seals ( Phoca vitulina concolour ) at Sable Island, Canada.
