Abstract The fitness of individual species depends on their ability to persist and establish at low densities, just as the diversity ecological communities establishment persistence low‐density, “invader” species. Theory predicts that abiotic conditions competitive make‐up resident jointly shape invader fitness, limiting phenotypic identity successful invaders. We use an invasion experiment ask how traits 20 introduced plant alter absolute in fragments differ size, conditions, community....
Abstract Do species and functional trait diversity respond similarly to deterministic random processes? Theory predicts that the contributions of processes depend on patch size. Smaller patches are more strongly influenced by sampling effects, having fewer individuals, as well ecological drift, which propagates effects small samples through stochastic birth death processes. These decrease richness increase compositional differences among patches. Larger predicted be deterministically...
