Resumen:
It has been argued that the structuring of ecological communities by niche processes is better revealed by considering the traits than identities of species. If this is true, then the coupling between the trait structure of a community and its environment should transcend changes in species identity. Biogeographic processes can lead to profound changes in species identity, as exemplified by taxonomic turnover across the Neotropics in the aquatic macroinvertebrates that inhabit bromeliads. We use surveys from 22 sites across Central America, South America and the Caribbean to test whether raitenvironment coupling is invariant despite this turnover. Although some sites show strong trait-environment coupling, these patterns are not universal, contrary to the current paradigms of trait-based ecology. This may reflect differences between species pools in their trait combinations, or differences between sites in how specific environmental gradients ameliorate limiting resources or conditions. We suggest that including such processes would allow an extension of trait-based ecology to meta-community and biogeographic scales.
