Review of Stress and the Measurement of Stress in Marine Mammals
MASSEY UNIV PALMERSTON NORTH (NEW ZEALAND)
Pagination or Media Count:
The objectives are to comprehensively review the literature on stress in cetaceans, stress in pinnipeds and stress in other marine mammals, and to devise and present a conceptual framework for considering stress in marine mammals that can be used by marine mammal researchers to consider how animals detect and respond to stressors over short and longer time periods. Summary tables will be prepared to list, for each group of marine mammals, key features of all published papers. Reported values for cortisol concentrations will be summarised in tables with details of sample collection conditions in order to provide readily accessible information on mean values and ranges of measured cortisol concentrations in different situations. This review is related to two projects which include investigations of the measurement of stress via quantification of blubber cortisol concentrations. These projects are Variability of hormonal stress markers collected from a managed dolphin population and Variability of hormonal stress markers and stress responses in a large cross-sectional sample of elephant seals.
