Community phylogenetics of Rocky Mountain lichens.

Community phylogenetic approaches have been used to infer ecological interactions that shape community assemblages, on the basis of evolutionary relatedness. The phylogenetic structure of a community has often been used to arbitrate between mechanisms of community assemblage. Communities whose species are phylogenetically clustered are inferred to be shaped by environmental filtering. Conversely, communities whose species are phylogenetically over-dispersed are inferred to be shaped by competitive exclusion. As both environmental filters and competitive pressures act upon the phenotypes of organisms, studies of community phylogenies often incorporate analyses of functional traits. The present study focuses on the lichen flora of the Rocky Mountains. This geographic region offers many compelling elevational gradients and an array of highly varied habitats. Here, we analyze subsamples of the Rocky Mountain lichen flora in order to determine how the phylogenetic structure of communities differs among varying environmental conditions. Included are analyses of two functional traits of lichens that have commonly been studied—growth form and reproductive mode.
