Abstract

The highly invasive New, Zealand mudsnail, Potamopyrgus antipodarum, may compete with and displace native North American macroinvertebrates in freshwater systems where cr it becomes established. Densities and spatial distributions of 3 snail species including P antipodarum and the threatened Taylorconcha serpenticola were compared am ng 3 adjacent habitat types (run, edge, and vegetation) in Banbury Springs, a tributary of the Snake River, near Hagerman, Idaho. USA. In all 3 habitats P. antipodarum was the most abundant snail species. All 3 species densities were highly variable within habitats, suggesting a nonrandom distribution pattern. Densities of P. antipodarum were significantly greatest in the vegetation habitat type, while densities of T. serpenticola were similar among habitats. Smaller-sized P. antipodarum were less abundant in the run habitat with its associated higher watervelocities. and their densities were negatively correlated with velocity. Densities of P. antipodarum also were negatively correlated with distance from the highly infested, man-made Morgan Lake. while T serpenticola densities were positively correlated with distance from Morgan Lake. Potamopyrgus antipodarum is a potential competitor with native aquatic species. althoughits colonization into some freshwater habitats may be limited.
