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

Figure 5

Principal component analysis (PCA) of biological indices comparison between three types of water. CL had the highest values of the Simpson diversity index (D), Margalef richness index (d), and Shannon-Weiner diversity index (). This was followed by OL and SL in the same order of indices. OL, Open lotic; SL, Seasonal lotic; CL, Closed lentic. D, Simpson diversity index; d, Margalef richness index; , Shannon-Weiner diversity index; J, Pielou evenness index. S-H, Silt-humus; M-G, Mud-gravel; M-S, Mud-sand.
