We studied three stream macroinvertebrate metacommunities and found that dispersal mode affects metacommunity structuring. Actively dispersing species were more environmentally structured than passively dispersing species. Spatial extent or environmental heterogeneity did not drive the differences among the metacommunities. Our study supports previous findings that species sorting is prevailing in metacommunities.
