Polychaete zonation on sandy beaches of São Sebastião Island, São Paulo State, Brazil

Abstract: This study was performed in the intertidal zone of Barra Velha, Perequê, and Engenho d'Água beaches, located on São Sebastião Island (São Paulo State, Brazil), to assess the composition, abundance, and zonation of the polychaete community in the intertidal zone. Four structurally different sectors were established, two on Barra Velha (I and lI), one on Perequê, and one on Engenho d'Água. Each sector was divided into 3 tidal levels (lower, middle, and upper), in which 5 or 6 random samples were taken seasonally… Show more

“…1) restrict water flow in both directions, effectively isolating that portion of the channel and greatly reducing the advantages of oceanic water dilution during rising tides and accentuating the negative impact of organic pollution discharge (Pereira et al, 2000). Species richness at intertidal stations 1 and 10 was higher than that found in other studies of Brazilian tropical estuarine systems (Corbisier, 1991), including that of the sandy-beach intertidal areas Reis et al, 2000;Denadai et al, 2001). Outer stations, both intertidally and subtidally, had a higher richness than other subtropical Brazilian soft-bottom communities (Borzone & Souza, 1997) and much higher than those of subtropical Atlantic estuaries Capitoli et al, 1978;Ieno & Bastida, 1998;Muniz & Venturini, 2001).…”

“…Essa instabilidade provavelmente dificulta o assentamento e recrutamento dos organismos nessa porção. Tais processos também moldam padrões semelhantes em praias arenosas, como observado por Reis et al (2000) no litoral norte de São Paulo. Em seu estudo é observado padrão de zonação similar para as três famílias, com Nereididae e Capitellidae ocupando principalmente as regiões superior e média, enquanto Spionidae é observada em maior densidade na porção inferior.…”

“…Inúmeros processos dos ecossistemas promovem padrões distintos de distribuição para os variados grupos na comunidade bentônica (Defeo & Mclachlan, 2005). Sabese, por exemplo, que planícies lamosas, praias e costões rochosos apresentam determinado padrão de zonação de organismos bentônicos, relacionado aos diferentes níveis de exposição aérea, ação da maré e das ondas (Stephenson & Stephenson, 1949;Netto & Lana, 1997;Reis et al, 2000). Essas informações, quando conhecidas para a área em questão, permitem que delineamentos amostrais eficientes sejam elaborados nos programas de monitoramento, trazendo maior efetividade à gestão costeira.…”
