Evolutionary physiology of timing of breeding
In many habitats, seasonal patterns in environmental conditions vary dramatically across the year. Most species have adjusted the timing of
their reproduction to the specific patterns in their particular environment. In my lab, we are investigating where in the physiological cascade
that regulates reproduction this adjustment has occurred, and whether this adjustment is the consequence of evolutionary changes in
physiological organization.
To answer these questions we have begun studies comparing the molecular organization of the photoperiodic system of great tit populations
in Europe. We will also investigate the fitness consequences of variations in photoperiodic responses to the environment, using great tits
as a model system.
