Developing Metrics of Animal Condition and their linkage to Vital Rates: Further Development of the PCoD Model

There is a growing understanding that adipose tissue releases hormones (adipokines) that help regulate metabolism, immune function and reproduction. This study examines changes in blubber gene expression and blood concentrations of adipokines in naturally fasting elephant seals, examines their relationship to immune markers and reproductive hormones, and will provide novel information on how body condition influences health and reproduction in wildlife.
