SOME IMPORTANT ATTRIBUTES WHICH REGULATES THE LIFE OF MACRO -INVERTEBRATES: A REVIEW

Aquatic habitats are known to support an extraordinary array of species. Aquatic biodiversity is one of the most important characteristics of the aquatic ecosystem for maintaining its stability and resilience. The macro-invertebrates have been found as the most common faunal assemblages for bio assessment and provide more reliable assessment of long term ecological changes in the quality of aquatic system compared to its rapidly changing physico-chemical characteristics. This review discusses some of the factors which regulate the occurrence and distribution of macro -invertebrates namely substrate, temperature, dissolved oxygen and water velocity & current.
