Research Interests

Climate Change, Conservation of Mammals and Birds, Population and Community Dynamics

I am interested in the factors that shape population and community dynamics, especially in the Arctic, where climatic and ecological responses to global change are expected to be most pronounced. My research involves many approaches aimed at divulging and understanding ecological consequences of climate change. The techniques I use include observational fieldwork, large-scale field experimentation, and quantitative analytical modeling of long-term data.

Current research projects include: (1) experimental manipulation of near-surface temperatures in arctic meadows to investigate spatial dynamics of plant phenological response to climate change; (2) analytical modeling of the role of large-scale climatic warming in the spatial dynamics of plant phenology and timing of bird migration; (3) observational monitoring of relationships between timing of reproduction by caribou and plant phenology in arctic Greenland; and (4) experimental assessment of the role of herbivory in mediating vegetation response to climate change.
