Effects of weir‐induced habitat fragmentation on the diversity and community composition of benthic macroinvertebrates in an agricultural stream

Entomological Research, Volume 54, Issue 9, September 2024.
Abstract This research delves into the effects of weir‐induced habitat fragmentation on the diversity and structure of benthic macroinvertebrate communities in Topyeong Stream in the Republic of Korea. Through comprehensive zonation, environmental assessments and analyses of macroinvertebrate populations, the study brings to light the significant ...
