| Resumo: |
The present study evaluated the predation effects of the gastropod Melanoides tuberculatus on the taxa richness and density of the periphyton community. A laboratory experiment was conducted with two treatments: control (without M. tuberculatus) and with M. tuberculatus, each treatment being replicated four times. For periphyton colonization, glass slides were placed in 3.5 L of water from the environment of the gastropods. The analysis of species richness and density of the periphyton community on these artificial substrates showed significant differences (p <0.05) between treatments. In the treatment with M. tuberculatus, taxa richness and density were lower, with a predominance of Chantrasia macrospora in the last days of the experiment. It follows that predation by M. tuberculatus destabilizes the course of periphyton colonization, suggesting the possibility of disruption of natural food chains, however, more studies are needed in this perspectives.
