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

Figure 2

Effects of three types of sediment on macroinvertebrates distribution in the SIBW. (a) The numbering of macroinvertebrates shows the mollusks were greater in (S-H). (b) Principal component analysis (PCA) based on the density and biomass of total macroinvertebrates in different sediment. The density of macroinvertebrates had a greater association with the S-H sediment and the M-S sediment had the least association. The largest biomass of macroinvertebrates in M-S, sediment. S-H, Silt-humus; M-G, Mud-gravel; M-S, Mud-sand.
