Predation effects of Melanoides tuberculatus Müller 1774) on periphytic biofilm colonization: an experimental approach Biota Neotropica
Vasconcelos,Janiele França; Barbosa,José Etham de Lucena; Azevêdo,Evaldo de Lira; Azevêdo,Daniele Jovem da Silva; Anacleto,Maria José Pinheiro.
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...
