Relationships between characteristics of macrobenthic assemblages and environmental variables in the Heihe River Basin, China

To clarify the characteristics of macrobenthic assemblages and their response to the aquatic environment in the upper and middle reaches of the Heihe River, water quality, sediments and macrobenthos measurements were conducted in the summers of 2018 and 2019. The results showed that 50 species of ma...
