Disentangling the role of environment in cross-taxon congruence of species richness along elevational gradients

Abstract Spatial patterns of species richness have been found to be positively associated, a phenom called cross-taxon congruence. This may be explained by a common response to environment or by ecological interactions between taxa. Spatial changes in species richness are related to energy and envir...
