Responses of non-native species to climatic change and their implications for management
Sam Ward, Mississippi State University
Abstract: The establishment and subsequent abundance of non-native species, such as introduced pests and the natural enemies imported to combat them, is in part determined by the climatic suitability of the novel habitat. For non-native species that have been established for decades, shifting climatic regimes could cause deviations from historical patterns of abundance. I will discuss some potential mechanisms for how climate change might alter host-parasitoid dynamics, using the invasion of, and importation biological program against, larch casebearer in North America as a case study.
