"Hierarchical Diversity of Communities of Aquatic Insects and Fishes"

摘要: : Hierarchical diversity analysis of data on fish and aquatic insects showed that the component contributed by species level was generally very small compared with at generic or total diversity. Very high rank correlations between diversity, in which genera were discriminated but not identified, suggested purposes environmental monitoring might best be served working rather than level. This is particularly true when an index to used as major comparative communicative tool. The savings time money could appreciable.
