My research addresses the direct thermal implications of historical climate and contemporary climatic change on endothermic organisms. I quantify the morphological, physiological and behavioral constraints upon thermoregulation for seabirds and waterbirds and how these influence breeding distributions, population processes, physiology and behavior.
My current projects and collaborations include:
Thermal ecology of seabirds and waterbirds in a changing world: comparative ecophysiology through fieldwork, measurement of preserved specimens and ecological modeling.
Interplay between climate and physiology: the strength of evolutionary selection pressures on morphology and physiology of extant seabirds, both currently and in historical time.
The ecology and conservation of declining, inland-breeding waterbird populations.
Development of novel field instrumentation and analytical methods for studying colonial birds.
I am interested in collaborations with students in any of these areas (please e-mail me).
