Structural property in communities of aquatic insects and benthic macroinvertebrates could reflect the impact of environment on aquatic ecosystems. Benthic macroinvertebrates were collected at 18 different lakes across different levels of environmental impact in Korea. Community responses were analyzed by species abundance distribution (SAD). Rank-abundance (or relative abundance) curves were evaluated by classical SAD (Geometric series, Log-series, and Lognormal distribution) and niche apportionment models (dominance pre-emption, random assortment, random fraction, and dominance decay). Geometric series was more accepted in lakes among classical SAD models. Niche apportionment models were observed in a diverse manner across different level of ecological integrity in lakes. Dominance decay model and random fraction model were frequently fitted to the lakes with higher integrity, while dominance pre-emption and random assortment models tend to be presented in low to middle range in integrity.
