【 摘 要 】

The diversity of annelids polychaete associated with intertidal mangrove biotope of the Santuario Nacional los Manglares de Tumbes is studied. Sampling was conducted at two sites, one near the river mouth and the other distant about 6 km upstream. In each place, two fixed stations were established, one associated to high intertidal zone with the presence of Anadara tuberculosa (ZBI) and other associated to low intertidal zone with the presence of Ucides occidentalis (ZAI). The samples were taken in December 2012 and March 2013. The total number of species registered was 57 species composition was not similar between associations and between fixed stations. The stations associated to ZBI had more number of species abundances and indices greater diversity than to ZAI. As trophic groups, the stations associated to ZAI had four groups whereas stations associated to ZBI had 6 trophic groups. The poliquetofauna associated with ZBI dominated in number of species, the carnivores while poliquetofauna associated to ZAI, was carnivores and surface deposit feeders also dominated in abundance subsurface deposit feeders. Multivariate analysis showed significant differences in the structure and trophic composition of partnerships, with greater dispersion and variability in the ZAI.
