- Abstract
This study analyzed the relationships between environmental parameters and benthic macroinvertebrate faunas. Invertebrate richness, Shannon-Wiener diversity, functional-group and CCA were used to evaluate conditions of waterbodies of the Hu-lan Estuary Natural Wetland Reserve and its hinterlands. We measured 10 physicochemical variables and collected 165 species belonging to 6 functional feeding groups (FFGs) during spring, summer and autumn. Some of the physicochemical factors changed with seasons. Nitrate nitrogen, total nitrogen and total phosphate significantly varied with seasons (p ˂ 0.05), unlike water temperature, depth, pH, dissolved oxygen, chemical oxygen demand, Ammonia nitrogen and electronic conductivity (p > 0.05). The taxa richness of benthic macroinvertebrates did not vary significantly within the sites (p = 0.508); while the Shannon-Wiener diversity showed significantly difference (p ˂ 0.01) within the sites over these three seasons. Gathering-collectors were the most abundant macroinvertebrate FFG assemblages all over the sites, though there’s no significant difference in the total abundance of 6 functional feeding groups identified among the sites during spring, summer and autumn (p = 0.677, p = 0.681, p = 0.302, respectively). Our CCA results indicated positive correlations of macroinvertebrate community compositions with environmental variables in the Hu-lan Estuary Natural Wetland Reserve and its surrounding waters.
