Ecology, Evolution and Behavior
Organisms today are faced with environmental change on a scale unknown in their evolutionary history. Their ancestral habitats have been converted to monocultures of crops or expanses of houses; ecosystem nutrient cycles are shifting due to fertilizer application; and the climate is changing rapidly. How will organisms respond to such novel and rapid changes in their environment? Not only is this a pressing question for conserving biodiversity, but it is also relevant for understanding how past environmental change has shaped modern biological diversity. My lab takes both a basic and applied approach to understanding responses to environmental change. We ask why are some developmental programs more flexible than others? What are the consequences of such variation in plasticity for survival and diversification novel environments? We focus on several novel, anthropogenic environments -- cities, agricultural environments and roadsides. In doing so, we also address conservation-related questions. Currently, a number of projects consider roadsides as habitat for insect pollinators, studying interactions between nutrients and roadside stressors in the development of butterflies and bees.
