Distribuição e ecomorfologia de Neritina zebra (Bruguiere, 1792) (Mollusca: Gastropoda: Neritidae), em um estuário amazônico, Pará, Brasil

O presente estudo avaliou a distribuição de Neritina zebra em um gradiente vertical em afloramentos rochosos e a distribuição entre os afloramentos de rochosos e argilitodo entremarés em um estuário na Amazônia brasileira. Os locais de coletas são caracterizados por águas oligohalinas, sendo localizadas nos distritos dede Icoaraci, Mosqueiro e município de Colares na região costeira do Estado do Pará. Para avaliar a distribuição vertical nos substratos rochosos, os moluscos foram amostrados na faixa inferior e média do mesolitoral. Na faixa inferior do mesolitoral, onde ocorrem os substratos argilito e rocha, estes foram amostrados para verificar seu efeito na distribuição entre os substratos. Em cada tipo de substrato e faixa do entremarés foram amostrados aleatoriamente 22 réplicas utilizando-se um quadrante de 25cm² na estação chuvosa e de estiagem. Análises de Variâncias foram realizadas para testar (1) o efeito da zona do entremarés e (2) o tipo de substrato na densidade de N. zebra. A análise dos resultados da distribuição vertical mostrou que a zona inferior os indivíduos juvenis apresentam maior densidade que a zona média, e um padrão oposto parece ocorrer com espécimes adultos. Quanto à distribuição nos diferentes substratos, os resultados mostraram que existem maiores densidades nos substratos rochosos que nos argilosos para os indivíduos juvenis, mas não foi encontrado um padrão para os indivíduos adultos. Esta variabilidade no padrão de densidades entre os substratos e entre as zonas do entremarés mostrou influência das estações e dos locais de coleta, apresentando Icoaraci com as menores densidades, o que pode estar associado à atividade antrópica naquela localidade.
