TLDR
A formal experimental test of the phylogenetic limiting similarity hypothesis using pairs of bacterivorous protist species in a multigenerational experiment supports phylogenetic relatedness as a useful predictor of the outcomes of competitive interactions in ecological communities.Abstract:
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 multigenerational experiment. Consistent with the hypothesis, both the frequency and tempo of competitive exclusion, and the reduction in the abundance of inferior competitors, increased with increasing phylogenetic relatedness of the competing species. These results were linked to protist mouth size, a trait potentially related to resource use, exhibiting a significant phylogenetic signal. The likelihood of coexistence, however, was better predicted by phylogenetic relatedness than trait similarity of the competing species. Our results support phylogenetic relatedness as a useful predictor of the outcomes of competitive interactions in ecological communities.read more

TL;DR: New T-statistics ('T' for trait) are introduced, based on the comparison of intraspecific and interspecific variances of functional traits across organizational levels, to operationally incorporate intrapecific variability into community ecology theory.

TL;DR: This review paper highlights differences between microbes and macroorganisms and generate hypotheses describing how these differences may be important for community assembly, and discusses the implications of microbial assembly processes for ecosystem function and biodiversity.

Plant functional traits and the multidimensional nature of species coexistence
TL;DR: These complex relationships between phenotypic differences and the dynamics of competing species argue against the simple use of single functional traits to infer community assembly processes but lay the groundwork for a theoretically justified trait-based community ecology.

Phylogenetic conservatism of functional traits in microorganisms
TL;DR: A framework for predicting the phylogenetic conservatism of functional traits depending on the complexity of the trait is proposed, which enables predicting how variation in microbial composition may affect microbially-mediated ecosystem processes as well as linking phylogenetic and trait-based patterns of biogeography.

The Limiting Similarity, Convergence, and Divergence of Coexisting Species
TL;DR: The total number of species is proportional to the total range of the environment divided by the niche breadth of the species, which is reduced by unequal abundance of resources but increased by adding to the dimensionality of the niche.
