摘要

Rivers and streams have been hypothesized to be corridors of earthworm dispersal through watersheds, but little direct evidence of their dispersal within water columns has been observed. Here we report captures of at least two living, non-native earthworm species from instream drift-netting in a large order river of the Northern Great Plains.
