We analysed aquatic insect richness and assemblage patterns in four coastal rivers of southeast Ivory Coast. In each river, two sites were sampled: one upstream and one downstream. In the eight sites, aquatic insects were randomly sampled eight times (i.e., four during the rainy season and four during the dry season) between July 2003 and March 2005. Overall, 124 taxa belonging to 53 families and ten orders were recorded. The richest taxon diversity was observed for Diptera and Ephemeroptera. The settlement of aquatic insects presented strong similarity between sites. In addition, beta diversity assessment showed that the dispersal of aquatic insects was random (Mantel tests, p >0.05) i.e., their taxonomic composition was homogeneous over the area covered by the four rivers, suggesting that they belong to the same ecoregion. So, as these rivers are subject to little anthropogenic disturbance compared to other streams in the same region, we suggest using them as reference systems with a view to initiating conservation and/or biomonitoring programs. |
