Stochastic competitive exclusion leads to a cascade of species extinctions.
Community ecology has traditionally relied on the competitive exclusion principle, a piece of common wisdom in conceptual frameworks developed to describe species assemblages. Key concepts in community ecology, such as limiting similarity and niche partitioning, are based on competitive exclusion. However, this classical paradigm in ecology relies on implications derived from simple, determinis...
متن کاملPhylogenetic limiting similarity and competitive exclusion.
One of the oldest ecological hypotheses, proposed by Darwin, suggests that the struggle for existence is stronger between more closely related species. Despite its long history, the validity of this phylogenetic limiting similarity hypothesis has rarely been examined. Here we provided a formal experimental test of the hypothesis using pairs of bacterivorous protist species in a multigenerationa...
متن کاملCorrection: Resource Availability Modulates the Cooperative and Competitive Nature of a Microbial Cross-Feeding Mutualism
Mutualisms between species play an important role in ecosystem function and stability. However, in some environments, the competitive aspects of an interaction may dominate the mutualistic aspects. Although these transitions could have far-reaching implications, it has been difficult to study the causes and consequences of this mutualistic-competitive transition in experimentally tractable syst...
متن کاملLimiting factors, competitive exclusion, and a more expansive view of species coexistence.
When I began graduate school in the 1980s, species interactions were viewed predominantly through the prism of resource competition. Species found together were largely understood to coexist because of how they segregated their use of the available spectrum of local resources. I entered this world of ideas wholeheartedly, but I was fascinated by why prey species are able to coexist with some pr...
