Abstract

A preliminary study of the composition and community structure of the foraminifera of Chichiriviche de La Costa (Vargas,
Venezuela) is presented. A total of 105 species were found in samples from 10 to 40 meter-depth, and their abundance quantified in a carbonate prone area almost pristine in environmental conditions. The general composition varies in all the samples: at 10 m, Miliolida dominates the assemblages but, as it gets deeper, Rotaliida takes control of the general composition. The Shannon Wiener diversity index follows species richness along the depth profile, meanwhile the FORAM index has a higher value at 20 m and its lowest at 40 m. Variations in the P/(P+B) ratio and high number of rare species are documented and a correspondence multivariate analysis was performed in order to visualize the general community structure. These results could set some basic information that will be useful for management programs associated with
the coral reef in Chichiriviche de La Costa, which is the principal focus for diver’s schools and tourism and could help the local communities to a better understanding of their ecosystem values at this location at Vargas State, Venezuela.

Keywords: Miliolida, Rotaliida, foraminiferal assemblages, FORAM index, Caribbean continental shelf.

RESUMO – Um estudo preliminar da composição e estrutura da comunidade de foraminíferos de Chichiriviche de La Costa (Vargas, Venezuela) é apresentado. Um total de 105 espécies foram encontrados em amostras de 10 a 40 m de profundidade e sua abundância quantificada em uma área carbonática quase intocada em termos de condições ambientais. A composição geral varia em todas as amostras: a 10 m, Miliolida domina a associação, mas à medida que se aprofunda, Rotaliida assume o controle da composição geral. O índice de diversidade de Shannon Wiener segue a riqueza de espécies ao longo do perfil de profundidade, enquanto o índice FORAM tem um valor mais alto em 20 m e seu mínimo em 40 m. Variações na razão P/(P+B) e número elevado de espécies raras foram documentadas, e uma análise multivariada de correspondência foi realizada a fim de visualizar a estrutura geral da comunidade. Esses resultados podem fornecer algumas informações básicas que serão úteis para programas de gestão associados ao recife de coral em Chichiriviche de La Costa, que é o principal foco para escolas de mergulho e turismo, o que pode ajudar as comunidades locais a um melhor entendimento dos valores de seus ecossistemas nesta localidade no Estado de Vargas, Venezuela.

Palavras-chave: Miliolida, Rotailiida, associação de foraminíferos, índice FORAM, plataforma continental caribenha.
