Resumo: Knowledge about biological diversity is essential for the establishment of measures that lead to the protection of natural resources. Sandy beaches are areas of high diversity, with the malacofauna being an important component. Several mollusks are of great economic importance and the spatial distribution of these species on sandy beaches is linked to physical and biological factors. The aim of this study was to analyze the diversity of the malacofauna associated with Anomalocardia flexuosa distribution on a tropical sandy beach. Samples were collected bimonthly between April 2016 and February 2018 at 34 points distributed throughout a sandbar. The frequencies of occurrence of the species were calculated, and diversity indices were estimated and correlated with the densities of A. flexuosa. A total of 4,780 individuals from 11 species were obtained. The most frequent species were A. flexuosa and Neritina virginea. There were significant correlations between A. fleuxosa density and diversity, and overlap occurred between mollusks over the collection months and sites. Therefore, targeted catches for this species should also consider all other mollusks to mitigate future damage to malacofauna diversity in the region.

As praias arenosas são áreas de alta diversidade, sendo a malacofauna um componente importante. Vários moluscos têm grande importância econômica e sua distribuição espacial, em praias arenosas, está atrelada a fatores físicos e biológicos. O objetivo deste estudo foi analisar a diversidade da malacofauna associada à distribuição de Anomalocardia flexuosa em uma praia arenosa tropical. As amostras foram coletadas bimensalmente, entre abril 2016 e fevereiro de 2018, em 34 pontos distribuídos ao longo de todo o banco de areia. Foram calculadas as frequências de ocorrência das espécies e os índices de diversidades foram estimados e correlacionados com as densidades de A. flexuosa. No total foram obtidos 4.780 indivíduos, pertencentes a 11 espécies. As espécies mais frequentes foram A. flexuosa e Neritina virginea. Há correlações significativas entre as densidades de A. fleuxosa com as medidas de diversidade ocorrendo sobreposição entre os moluscos ao longo dos meses e dos locais de coleta. Portanto, as capturas dirigidas para essa espécie devem também considerar todos os outros moluscos para mitigar futuros danos à diversidade da malacofauna na região.Universidade Federal de Santa Catarina2019-12-12info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2019v32n4p5110.5007/2175-7925.2019v32n4p51Biotemas; v. 32 n. 4 (2019); 51-622175-79250103-1643reponame:Biotemas (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCporhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2019v32n4p51/42051Copyright (c) 2019 Severino Adriano Oliveira Lima, Ana Júlia Rufino Freitas, Humber Agrelli Andradeinfo:eu-repo/semantics/openAccessLima, Severino Adriano OliveiraFreitas, Ana Júlia RufinoAndrade, Humber Agrelli2019-12-12T07:56:23Zoai:periodicos.ufsc.br:article/64904Revistahttp://www.biotemas.ufsc.br/index.htmPUBhttps://periodicos.ufsc.br/index.php/biotemas/oai||carlospinto@ccb.ufsc.br2175-79250103-1643opendoar:2019-12-12T07:56:23Biotemas (Online) - Universidade Federal de Santa Catarina (UFSC)false
