Regional Impacts

Ecological ImpactCompetition
Potamopyrgus antipodarum was the dominant gastropod in a community of freshwater snails in olgiohaline enclosed marshes, and was the only species in mesohaline marshes. This was attributed to parthenogenesis, high reproductive output, and scarcity of trematode parasites (Gerard et al. 2003).
