A Study on the Tolerance Value and Biodiversity of Benthic Macroinvertebrates

Abstract:

Macroinvertebrates are important components of stream ecosystems. A field experiment was conducted to study the effects of substrate particle size, shape, and roughness on the composition and biodiversity of macroinvertebrates. The results show that the particle sizes, porosity, and interstial dimensions of the substrate affect the macroinvertebrate community, while the shape and surface roughness of the substrate do not strongly affect the macrobenthos composition and density. The macroinvertebrate composition in gravel is stable. The density and species richness in the gravels, leaf humus and are much higher than those in the black silt and sands.
