Effects of Habitat Types on Macroinvertebrates Assemblages Structure: Case Study of Sun Island Bund Wetland

Figure 4

The effects of three types of water state on distribution macroinvertebrates in the SIBW. (a) The numbering of macroinvertebrates (mean ± SD). In the closed lentic area and the open lotic area, the aquatic insects were dominant followed by mollusks. While the seasonal lotic area was dominated by mollusks > aquatic insects > annelids and crustaceans. (b) Principal component analysis (PCA) of the density and biomass of total macroinvertebrates in different sediment, where the density and biomass of macroinvertebrates are almost a similar trend with CL having the highest values followed by OL and then SL. S-H, Silt-humus; M-G, Mud-gravel; M-S, Mud-sand.
