Alexander (Sasha) Kitaysky

Research Interests: 

The main focus of my current research program is on the fundamental question: 
Can we predict population responses (range shift, adaptation or extinction) to an environmental change based on current phenotypic and biological age structures of natural populations of marine top-predators?

Specifically, I am interested in (A) how climate- and human induced environmental changes affect physiology, reproduction and survival of different phenotypes in wild seabird populations; and (B) the consequences of such differential selection pressure on individuals for the spatial and temporal dynamics of their populations.
