Composição e estrutura da comunidade fitobentônica do infralitoral da praia de Itaipu, Niterói, Brasil: subsídios para monitoramento e conservação

Year: 2014

Type: article

Abstract: This study aimed at evaluating both quali- and quantitatively the assembly of macroalgae andassociated organisms from the rocky shore at Itaipu beach, Niteroi, Rio de Janeiro. Richness and diversity were calculated as well as species equitability. The temporal variation ofmacroalgal dry mass was also evaluated according to morphofunctional groups. We 26 identifi ed taxa: Chlorophyta (7), Ochrophyta (3) and Rhodophyta (16). Foliose macroalgae from the genus Ulva, were the most abundant. The low richness and species diversity, proliferation of Ulva, considered opportunistic, and the absence of brown algae, during most of the study, may indicate the environmental impacts, mainly eutrophication, since the site receives sediment discharge from Guanabara Bay. Therefore, we suggest the constant monitoring of this region through the use of macroalgal assemblages.
