Dissecting drivers of community assembly in a comparative phylogenetic framework.

Understanding the process of community assembly is a key question in evolutionary ecology. Darwin predicted that distantly related non-native species would be more likely to establish due to novel traits that allow escape from competition with close relatives that are already present in the community. Various attempts have been made to test this hypothesis by studying patterns of species invasions, however, each has considered different spatial and taxonomic scales, and used different methods for incorporating phylogenetic history in their analyses. The objective of this study is to understand how natural communities assemble at different spatial and taxonomic scales, using a well-defined conceptual framework and consistent analytical methods with invasive species on oceanic islands and in alpine regions as comparative study systems. Further, we dissect the mechanisms that are producing the patterns of invasion that we observe for different biogeographic factors by incorporating comparative analyses of plant functional traits and rates of diversification to elucidate what makes some communities more invasible than others.
