Variation in hydrochory among lakes and streams: Effects of channel planform, roughness, and currents

The configuration of channels in stream networks is vital for their connectivity, biodiversity, and metacommunity dynamics. We compared the capacity of three process domains—lakes, slow‐flowing reaches, and rapids—to disperse and retain plant propagules by releasing small wooden cubes as propagule mimics during the spring flood and recording their final locations. We also measured the geomorphic characteristics (planform, longitudinal profile,...
