AbstractEpifauna associated with algae cover plays an important role in marine ecosystems, since it provides food for species that are higher up in the food chain. To characterize the potential prey of the syngnathids and their possible spatio-temporal variations, a study was conducted to characterize the epifauna associated with the main habitat-forming algae species in the Cies Islands. In addition, stable isotope analyses (SIA) were carried out to know the trophic structure of the community. Samples of Asparagopsis armata, Codium sp. and Cystoseira baccata were collected in three different zones (A, B, C) and subzones of the archipelago in spring, summer and autumn for two years (54 samples in total). The individuals collected were quantified and separated by the lowest possible level of identification. PERMANOVA analyses were made using the factors year (fixed), algae species (fixed), season (random, nested in year), zone (random, nested in algae species) and subzone (radom, nested in zone). From each of the groups that were formed, the most species were chosen for SIA.
