Resumo: | According to the Theory of Island Biogeography, the relation species to area and spatial isolation can influence the distribution of species in habitats. Thus, lentic ecosystems are used to provide information on local mechanisms of diversity of organisms, including mollusks. The present study evaluated the ecological and biogeographic aspects of limnic mollusks by assessing the influence of the size and distance of water bodies on the distribution of species. Sampling was carried out in lagoons, classified by perimeter and with different distances, in Acaraú, Ceará. A total of 2,067 gastropods were collected; they were distributed in six families, six genera and nine species and included the planorbids Biomphalaria glabrata and Drepanotrema cimex, which had not yet been recorded for Ceará. No significant differences were observed in richness, abundance and diversity in relation to the size of the lagoons. However, there was a tendency for higher indices in medium-sized ponds, which may be due to intermediate disturbances. Similarities in community structure between nearby water bodies were not observed, which can be explained by the ease of dispersion of species due to flooding during rainy periods. The data presented here may be important for understanding the mechanisms responsible for the distribution patterns of limnic mollusks in northeastern Brazil. |

Na Teoria da Biogeografia de Ilhas, a relação espécies-área e o isolamento espacial podem influenciar na distribuição de espécies nos habitat. Nesse contexto, ecossistemas lênticos são utilizados para fornecer informações sobre mecanismos locais de diversidade de organismos, entre eles, moluscos. O presente estudo avaliou os aspectos ecológicos e biogeográficos de moluscos límnicos verificando a influência do tamanho e distância dos corpos hídricos na distribuição das espécies. A amostragem foi realizada em lagoas, classificada por perímetro com diferentes distâncias entre elas, em Acaraú, Ceará. Foram capturados 2.067 gastrópodes, distribuídos em seis famílias, seis gêneros e nove espécies. Foram coletados os planorbídeos Biomphalaria glabrata e Drepanotrema cimex, que ainda não haviam sido registrados para o Ceará. Não foram observadas diferenças significativas na riqueza, abundância e diversidade em relação ao tamanho das lagoas. Entretanto, há uma tendência de maiores índices em lagoas médias, o que pode ser resultante de distúrbios intermediários. Também não foram observadas similaridades na estrutura da comunidade entre corpos de água próximos, o que pode ser explicado pela facilidade de dispersão das espécies devido à enchente em períodos chuvosos. Os dados aqui apresentados podem ser importantes para compreensão dos mecanismos responsáveis pelos padrões de distribuição de moluscos límnicos no nordeste brasileiro.Universidade Federal de Santa Catarina2018-11-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2018v31n4p3510.5007/2175-7925.2018v31n4p35Biotemas; v. 31 n. 4 (2018); 35-462175-79250103-1643reponame:Biotemas (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCporhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2018v31n4p35/37927Copyright (c) 2018 Marcos Roberto Santos, Rafaela Camargo Maiainfo:eu-repo/semantics/openAccessSantos, Marcos RobertoMaia, Rafaela Camargo2019-03-01T15:43:21Zoai:periodicos.ufsc.br:article/57456Revistahttp://www.biotemas.ufsc.br/index.htmPUBhttps://periodicos.ufsc.br/index.php/biotemas/oai||carlospinto@ccb.ufsc.br2175-79250103-1643opendoar:2019-03-01T15:43:21Biotemas (Online) - Universidade Federal de Santa Catarina (UFSC)false |
