Global change stressors, including climate change and variability and changes in land use, are major drivers of ecosystem alterations. Invasive species, which are n-native species that cause environmental or ecomic damages or human-health impacts, also contribute to ecosystem changes. Invasive species are a major issue both ecologically and ecomically, and threaten native species, sometimes to the point of extinction. The interactions between stressors and invasive species, although t well understood, may exacerbate the impacts of climate change on ecosystems, and likewise, climate change may enable further invasions. This book reviews available literature on climate-change effects on aquatic invasive species (AIS) and examines state-level AIS management activities.
