Number of taxa and abundance per feeding group were measured for the two studied sponges, while density of symbionts per feeding group was calculated for every sponge specimen.…”

In the bay of Concarneau, we investigated the structural (i.e. species richness and species composition) and functional (i.e. biological traits) diversity of the macrofauna associated with this Haploops community as a comparison with several surrounding softsediment communities to determine the effect of this engineer species on ecosystem functions.We showed that the occurrence of Haploops tubes and individuals significantly modify sediment 20 features (e.g. change in sediment grain size, increase in C and N organic content) but also largely affect species diversity and benthic composition. The species richness is significantly higher but most importantly the species assemblage associated with Haploops habitat is very homogeneous and unique with 33% of all species exclusively found in this community. We also tested the effect of tube density on species diversity and abundances and the intermediate disturbance hypothesis but we showed 25 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 2 surprisingly no significant changes. Multivariate analysis (dbRDA) revealed that Haploops density was by far the factor explaining most of the variation in species composition of benthic communities. *Manuscript Click here to view linked ReferencesA biological trait analysis performed on selected traits revealed that the functional structure of the Haploops community was characterized by a greatly reduced proportion of small to medium long lived, sensitive to disturbance, free living or burrowing/tube-building filter-feeding species.Haploops 30 nirae appears to be a bioengineer and a foundation species that largely modifies its hydro-sedimentary features, controlling diversity and abundances of associated species, and creating a complex set of positive and negative interactions so that a unique benthic assemblage is found in sediments they colonized. 35 Keywords:Engineer species Ampeliscidae tube mats Macroinfauna diversity Intermediate disturbance hypothesis 40Biological trait analysis Bay of Biscay

“…In São Sebastião, the faunal groups found associated with Tedania ignis are also commonly found associated with macroalgae (Nascimento & Rosso, 2007), as also observed for the fauna associated with sponges elsewhere (Peattie & Hoare ,1981;Klitgaard, 1995;Voultsiadou et al, 2007;Huang et al, 2008;Fiore & Jutte, 2010). Epifaunal activities may clean sponge surfaces from debris, by feeding and building tubes, while the sponge provides a perennial and physically stable structure for the fauna (Costello & Myers, 1987).…”

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 diff erences 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.KEYWORDS. Biogenic substrate, associated fauna, diversity indicators, temporal variation.RESUMO. Variação temporal das assembleias de epi-e endofauna associadas com a esponja vermelha Tedania ignis em um costão rochoso (Canal de São Sebastião), SE, Brasil. 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 infl uência dos fatores abióticos. Observou-se que a massa seca da esponja infl uenciou 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 infl uenciou 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.PALAVRAS-CHAVE. Substrato biológico, fauna associada, indicadores de diversidade, variação temporal.
