Disentangling drivers of colonization success in laboratory and natural systems
Understanding why colonizing populations successfully establish is important for predicting dynamics of invasive species. Propagule pressure, or the number of individuals in a founding group, is considered the most consistent predictor of establishment success, however, there remains considerable variance around predictions that demography alone cannot explain. The identity of individuals within a founding group (e.g. level of pre-adaptation to the recipient environment, diversity) as well as how individuals are introduced (e.g. frequency and timing of discrete introduction events) can influence ...
