Abstract - A grand challenge in ecology is predicting how natural systems respond to climatic change. To address this challenge, many studies rely on statistical models that combine species occurrence data with abiotic predictors to forecast future biodiversity patterns. However, a number of uncertainties associated with this approach remain, including (1) the role of population-level adaptation to climate in mediating species responses, (2) whether incorporating community-level data improves models, and (3) the validity of extrapolating to novel climates of the future. In this seminar, I will discuss how new insights from ecological genomics and the paleo-record can help address these uncertainties and inform predictions of ecological responses to climate change.
Biography - Dr. Fitzpatrick is interested in how spatial and temporal variation in climate drive ecological patterns and processes, with an emphasis on developing and testing statistical methods to quantify how historic and current processes influence the distribution of species, patterns of biodiversity, and range expansion of native and introduced organisms. While he is most interested in terrestrial plant biodiversity, his research spans terrestrial and aquatic systems and biological scales of organization - from genes within genomes to species assemblages across the globe - and scales of time from the late Quaternary to the next century.
