Niveles de penetración de los diferentes grupos macroinfaunales en los sedimentos arenosos sublitorales de la ría de Ares y Betanzos (Galicia) (noroeste de la península Ibérica)
Sublittoral sandy bottoms of the Ria de Ares y Betanzos (Galicia, northwest Iberian Peninsula) were studied to determine the dominance patterns of macrobenthic faunal groups at different depth levels in the marine sediment. Samples of 20-25 cm average depth and 0.012 m² surface were analysed, consid...

| Sumario: | Sublittoral sandy bottoms of the Ria de Ares y Betanzos (Galicia, northwest Iberian Peninsula) were studied to determine the dominance patterns of macrobenthic faunal groups at different depth levels in the marine sediment. Samples of 20-25 cm average depth and 0.012 m² surface were analysed, considering 5 faunal groups: polychaetes, molluscs, crustaceans, echinoderms, and others. Our abundance results show the highest values for polychaetes, mainly near the surface, which decline with penetration into the sediment, where molluscs and the others group reach important relative values. |
