Environmental niche models for riverine desert fishes and their similarity according to phylogeny and functionality
James E. Whitney, Joanna B. Whittier, Craig P. Paukert
2017, Ecosphere (8) 1-21
Environmental filtering and competitive exclusion are hypotheses frequently invoked in explaining species' environmental niches (i.e., geographic distributions). A key assumption in both hypotheses is that the functional niche (i.e., species traits) governs the environmental niche, but few studies have rigorously evaluated this assumption. Furthermore, phylogeny could be associated with these...
