Resumo
Environmental factors and dispersal can influence the structure of biological communities. Their effects can depend on the
functional features of the species in the community. Since species belonging to the same trophic level, such as phytoplankton,
may show functional differences, we investigated whether the effects of environment and dispersal differ among phytoplankton
species from different functional groups. We analyzed data from a rainy and a dry period in 30 reservoirs in a subtropical
region. In both periods, the environment as well as high and limited dispersal influenced the metacommunity structure.
The functional groups had a low correspondence in their response to both dispersal and environment. Our results showed
that the influence of the processes underlying the structure of the metacommunities, such as species sorting (environment
influence), mass effect (high dispersal), and neutral dynamics (limited dispersal), depended on the functional characteristics
of the organisms and could vary even among species of the same trophic level. These findings suggested that species at the
same trophic level could not be considered ecological equivalents. This paper includes a Portuguese and Spanish version
of the abstract in the online resources.
