The consequences of maternal effects and environmental conditions on offspring success in an Antarctic predator

This is due to the challenges of having adequate data on the survival and reproductive outcomes for numerous offspring born in diverse environmental conditions to mothers with known and diverse sets of traits. This research project will evaluate the survival and reproductive consequences of early-life environmental conditions and variation in offspring traits that are related to maternal attributes (e.g. birth date, birth mass, weaning mass, and swimming behavior) in a population of individually marked Weddell seals in the Ross Sea.

Results will allow an evaluation of the importance of different types of individuals to the Weddell Seal's population sustenance and better assessments of factors contributing to the population dynamics in the past and into the future. The project allows for documentation of specific individual seal's unique histories and provisioning of such information to the broader science community that seeks to study these seals, educating graduate and undergraduate ecology students, producing science-outreach videos, and developing a multi-media iBook regarding the project's science activities, goals and outcomes.
