| Abstract |
The aim of this study was to identify the different trophic groups of Nematoda and the influence of environmental variables on the distribution of these groups on the different areas and zones from the beach of Barra da Tijuca, Rio de Janeiro. The sampling was carried out in November, December 2007 and January 2008 (wet season) and May, June and July 2008 (dry season) on two areas with different degrees of anthropogenic influence of two distinct zones of the sand beach. The meiofauna was composed of 17 taxonomic groups. On the Quebra-Mar area, Nematoda represented 22% of total meiofauna during the wet season and only 8% on the dry season. On the Reserva, the nematodes represented 10% of the total meiofauna during the wet season and 3% on the dry season. Four trophic groups were found during the sampling period, and the herbivores were the most abundant on the wet period. On the dry period, the detritivores non-selective were dominant. The granulometric characteristics and microphitobenthos were those, which presented the highest correlations with trophic groups of nematods. |
