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

Figure 8

Principal component analysis (PCA) of preference mapping of macroinvertebrates distribution in the Sun Island Bund Wetland. Biotic index, density, and biomass comparison between three types of sediment, water state, and vegetation. The higher values of macroinvertebrates density, biomass, diversity, and number of species were recorded in the habitat types of silt-humus sediment, closed lentic area, and submerged-flouting-emergent vegetation. S-H, Silt-humus; M-G, Mud-gravel; M-S, Mud-sand. OL, Open lotic; SL, Seasonal lotic; CL, Closed lentic. S-F-E, Submergent-flouting-emergent vegetation; F-E, Flouting-emergent vegetation; E, Emergent vegetation. 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.
