TLDR
The results show that communities built from species-rich pools develop more slowly to invasion-resistant states, and that saturation of local communities such that the number of species present locally becomes uncoupled from the richness of the pool.About:

Community ecology theory as a framework for biological invasions
Katriona Shea,Peter Chesson +1 more
TL;DR: The concept of "niche opportunity" was introduced by as discussed by the authors, which defines conditions that promote invasions in terms of resources, natural enemies, the physical environment, interactions between these factors, and the manner in which they vary in time and space.

Impact: Toward a Framework for Understanding the Ecological Effects of Invaders
Ingrid M. Parker,Daniel Simberloff,Karen Goodell,Marjorie J. Wonham,B. Von Holle,L. Goldwasser +5 more
TL;DR: This paper argues that the total impact of an invader includes three fundamental dimensions: range, abundance, and the per-capita or per-biomass effect of the invader, and recommends previous approaches to measuring impact at different organizational levels, and suggests some new approaches.

Are there general laws in ecology
TL;DR: It is argued that ecology has numerous laws in this sense of the word, in the form of widespread, repeatable patterns in nature, but hardly any laws that are universally true.

Historical Contingency in Community Assembly: Integrating Niches, Species Pools, and Priority Effects
TL;DR: The order and timing of species immigration during community assembly can affect species abundances at multiple spatial scales, and two requirements must be satisfied for historical contingency to occur: the regional pool contains species that can together cause priority effects, and local dynamics are rapid enough for early-arrived species to preempt or modify niches before other species arrive.

Are communities saturated? On the relationship between α, β and γ diversity
TL;DR: Using the concepts of α, β and γ diversity, it is shown that local–regional richness curves are determined by the way total diversity is partitioned between its α and β components, which is a matter of scale.
