Distribución y abundancia de macrobentos en la reserva de producción faunística manglares del salado del golfo de Guayaquil para la estación seca del año 2014

Abstract

Two sampling events were conducted during the dry season in November 2014 (November 4 and 19) at the Manglares del Salado Wildlife Production Reserve (Puerto Hondo). Work was carried out at four stations—Puerto Hondo, Madre Costal, Plano Seco, and Tres Bocas—with three replicates each; water and sediment samples were collected. The Salado Estuary is characterized by conditions typical of anoxic environments, a result of the pollution affecting the area. Statistical analysis revealed no significant differences between the parameters, so the data from both sampling events were averaged. A total of four phyla were identified; the phylum Annelida showed the highest relative abundance (96.64%), with the family Capitellidae accounting for 87.22% of this abundance, followed by oligochaetes at 4.26%.
