Environmental Perturbations, Behavioral Change, and Population Response in a Long-Term Northern Elephant Seal Study
A major challenge in marine mammal conservation and management is to understand how behavioral responses affect populations. To address this challenge, the National Research Council established the Committee on Characterizing Biologically Significant Marine Mammal Behavior. This committee developed...
