Evaluation of the community structure of marine sponges in reef patches of the southern Caribbean, Costa Rica Boletín de Investigaciones
Araya-Vargas,Alexander; Busutil,Linnet; García-Rojas,Andrea; Pereira-Chaves,José Miguel; Piedra-Castro,Liliana.
ABSTRACT Marine sponges fulfill many critical functions to coral reefs. In turn, variations in the community structure of the poriferans may indicate changes in the environmental conditions of the ecosystems where they live. However, their study has been scarce in the Caribbean of Costa Rica, mainly in the ecological field. Therefore, the community structure of these organisms was evaluated in four reef patches (Perezoso, Pequeño, Coral Garden, and the 0.36) and it was determined whether it could be explained by sedimentation, substrate, and depth. Relative abundance (RA) and relative coverage (RC) for each species, sponge density, and diversity indices (species richness, Shannon heterogeneity, Pielou's evenness, and Simpson's dominance) were calculated...
