Physiological and behavioral thermoregulation of northern elephant seals among three northern California rookeries - Livestream

The physiological adaptations that have allowed marine mammals to overcome the challenges associated with the recolonization of the aquatic environment confer unique life history traits that are uncommon in terrestrial mammals and have converged independently in distinct lineages. While these life history strategies make marine mammals interesting models to study adaptations to stress, perturbations characteristic of modern environments may increase marine mammals’ susceptibility to direct and indirect anthropogenic stressors. My dissertation seeks to contribute to our understanding of the effects of stress exposure through three projects that address the impacts of environmental stress at different levels of biological organization in marine mammals. In the first chapter of my dissertation, I am developing a model to study stress responses at the cellular level in seals and whales. In the second chapter, I use infrared thermal imaging to study physiological responses to climate change induced by habitat degradation in Northern elephant seals. In my last chapter, I will study the mechanisms driving neurological decline in California sea lions exposed to domoic acid.
