Summary

Dispersal, establishment, and spread of aquatic invasive species such as the zebra mussel (Dreissena polymorpha) can be influenced by riverine velocities and volumetric flows in invaded lake-stream ecosystems. Zebra mussels, which have a planktonic larval form (veliger), disperse rapidly downstream from a source population. Concentrations, dispersal, and body conditions of zebra mussel veligers were studied under different volumetric flow, or discharge, conditions in a coupled lake-stream ecosystem in northern Texas, USA. Veliger densities in lotic environments were strongly related to population dynamics in upstream lentic source populations. A strong exponential decrease in veliger density was observed through a 28-km downstream [...]

Purpose

Data were collected to assess downstream dispersal dynamics and body condition of zebra mussel veligers under different flow conditions in a coupled lake-stream ecosystem in north Texas. Veliger flux data were reported from one site, A1, which has a USGS streamflow-gaging station.
