Northern elephant seals females in the expanding population at A~ Nuevo live longer than southern elephant seal females at colonies whose populations are declining, which suggests that high survival of females is a key factor in population growth.

Monitoring of larvae in the field was successful, generating a predicted 16.4% survivorship from hatching to pupation, and the Mayfield method of data collection and analysis may be a useful tool for some studies of survivorship in free-living lepidopteran larvae.
