Marginal male hypothesis explains minor density differences in pinniped colonies

nature.com

A new model suggests the marginal male hypothesis explains only minor density differences in pinniped colonies. The model, inspired by Antarctic fur seals, incorporates mate choice and density-dependent pup survival, but predicted density variations were smaller than observed in the field. Researchers believe additional environmental factors are needed to fully explain observed spatial density variations in pinniped populations.
