          Abstract

          ABSTRACT Sponges are biogenic substrates that increase the available space on rocky shores and provide shelter for many groups of the benthic fauna, which can live both inside and on these sessile invertebrates. In order to assess the differences in temporal variation of endobiont and epibiont groups, samples of the red sponge Tedania ignis (Duchassaing & Michelotti, 1864) were obtained each month for one year. The density, richness and diversity of endobiont and epibiont groups were analyzed in relation to abiotic factors. The dry mass of the sponge was negatively correlated with the density of individuals in both groups and positively with the diversity of endobionts, while organic matter was positively correlated with the diversity of epibionts. Endobiont diversity was more highly correlated with intrinsic factors of the sponge, whereas the diversity of epibionts was more highly correlated with factors related to the surrounding environment.

          RESUMO As esponjas são substratos biogênicos que aumentam o espaço tridimensional disponível nos costões e proporcionam abrigo para uma grande numero de táxons da fauna bentônica, que podem viver tanto dentro como sobre esses invertebrados sésseis. Buscando avaliar as diferenças na variação temporal de táxons endobiontes e epibiontes, foram obtidas amostras mensais da esponja Tedania ignis (Duchassaing & Michelotti, 1864) durante um ano. Foram analisadas a densidade, riqueza e diversidade dos táxons endobiontes e epibiontes que foram relacionadas com a influência dos fatores abióticos. Observou-se que a massa seca da esponja influenciou negativamente a densidade de indivíduos nos dois grupos e apresentou resultado positivo sobre a diversidade de endobiontes, enquanto que a matéria orgânica foi o fator que influenciou positivamente a diversidade de epibiontes. Foi avaliado que a diversidade de endobiontes depende mais de fatores intrínsecos da esponja enquanto que a diversidade de epibiontes está mais relacionada com os fatores condicionados pelo meio ao redor.
