- Title
Are land bird assemblages functionally saturated? An empirical test in Mexico.
- Authors
de Silva, Héctor Gómez; Medellin, Rodrigo A.
- Abstract
Ecological theory attempts to explain community composition based on "assembly rules" that link resource use by species from a regional species pool with resource availability. The basic premise of these studies is that any community in an environment containing unused resources will either tend to be invaded by a species able to harvest that resource or, if such a species does not exist, natural selection will cause selection pressure for such a species to evolve. The resulting pattern of species richness has been described as the tendency for communities to be saturated.
