Environmental Filtering Maintains Macroinvertebrate Diversity in the Upper Jinsha River.

ABSTRACT: Elucidating the mechanisms that influence the assembly and maintenance of communities is a crucial objective in ecological research. However, the mechanisms underlying the maintenance of macroinvertebrate community structure in large rivers on the Tibetan Plateau are still not well understood. To this end, we systematically investigated the spatial distribution characteristics of community diversity and its maintenance mechanisms, focusing on the upper Jinsha River as our study region. During the period from November to December 2022, we collected a total of 126 macroinvertebrate species, representing 5 phyla, 7 classes, 14 orders, 53 families, and 96 genera. Our findings revealed notable variations in species composition among macroinvertebrate communities inhabiting the mainstem and its
