Abstract
Invasive species are often considered a global threat due to their association with biodiversity loss and novel diseases. The Missouri-Mississippi River Watershed, including the Missouri River Basin, is particularly vulnerable to invasive species because of low species diversity following historic glaciation events. Management of invasive species is imperative in this watershed but continues to be challenging in that there are over 100 invasive species currently present in this region. The goal of this project is to identify characteristics associated with successful invasions that may assist in developing management strategies to reduce the negative outcomes caused by the establishment of invasive species. This meta-analysis explored 17 life history characteristics of invasive species in the Missouri-Mississippi River Watershed that could be used to predict establishment success of invasive species. This was carried out by collecting data through literature review, followed by constructing and analyzing linear models. The results suggest that the life history characteristics that best predicted establishment success within this region include the species’ natal origin, native habitat, degree of parental care, maximum fecundity, maximum lifespan and propagule pressure. This was the first study to construct a predictive model for establishment success within the Missouri-Mississippi River watershed and will aide in future management strategies for stocking non-native species.
