Invasive species have dramatically changed the character of the landscape in many parts of the world, altering ecological processes and dramatically reducing populations of native species. Currently, the United States spends approximately $120 billion a year to control or contain some of these non-indigenous species. At the same time, changes in climate have markedly affected the developmental events of species; the great majority of observed phenological shifts have occurred in the direction that would be expected under warming. Despite some educated speculation, relatively little is known about whether global climate change will differentially favor nonnative species. Several of our speakers will present empirical research that touches upon this topic, including two studies in which climatic factors are experimentally manipulated. Nonnative species will likely expand or contract their ranges in response to the changing climate, with implications for both the impacts of these species and how the species are managed. Two of our speakers will explore the utility and sensitivity of bioclimatic models. One of our speakers will discuss the biotic and abiotic drivers of the northward expansion of an invasive insect’s range. A greater understanding of the likelihood for nonnative species expansion with climate change will allow managers to prepare for likely future invasions. Laying a strong foundation for the understanding of nonnative species responses to climate change will allow for optimal species management. Speakers in this organized oral session will explore the effects of climate change on nonnative species response and expansion, delve into the differences between native and nonnative species responses, as well as propose policy and management options for expanding populations of nonindigenous species. The research presented in this session reflects the forefront of research on the ecological effects of climate change on nonnative species and will provide an excellent bridge between basic and applied science concerning this critical issue.
