Landscape, demographic, and dispersal parameters influence the spread and establishment of an aquatic biological invasion
Abstract Human‐mediated species introductions are contributing to the biotic homogenization of global flora and fauna. Despite extensive research, we lack simple methods of predicting how and where an introduced species will spread and establish, particularly in species with complex life histories i...

Abstract Human‐mediated species introductions are contributing to the biotic homogenization of global flora and fauna.
