Salinity Tolerance Of Larval Rapana Venosa: Implications For Dispersal And Establishment Of An Invading Predatory Gastropod On The North American Atlantic Coast, Roger L. Mann, Juliana M. Harding
Salinity Tolerance Of Larval Rapana Venosa: Implications For Dispersal And Establishment Of An Invading Predatory Gastropod On The North American Atlantic Coast, Roger L. Mann, Juliana M. Harding

The lack of quantitative data on the environmental tolerances of the early life-history stages of invading species hinders estimation of their dispersal rates and establishment ranges in receptor environments. We present data on salinity tolerance for all stages of the ontogenetic larval development of the invading predatory gastropod Rapana venosa, and we propose that salinity tolerance is the dominant response controlling the potential dispersal ( = invasion) range of the species into the estuaries of the Atlantic coast of the United States from the current invading epicenter in the southern Chesapeake Bay. All larval stages exhibit 48-h tolerance to salinities …

Snapping shrimp in the family Alpheidae are remarkably abundant in coral reef ecosystems worldwide. The second most speciose genus, Synalpheus , includes species usually small and reclusive, and their general morphology is notably uniform, yet the number of species is staggeringly high, as is the intraspecific variability. These features have contributed to a poorly resolved taxonomic status, as evidenced both by recurring lumping and splitting of species and by lack of proper definition of several common species. I examined western Atlantic species of Synalpheus in the large and regionally dominant "Gambarelloides group of species", an informal but widely used guild …

Reports
This booklet gives information and data-based exercises describing ecological and economic connections between introduced rapa whelk Rapana venosa predators and local hard clams Mercenaria mercenaria in the lower Chesapeake Bay. The information is focused to answer the question: "How many hard clams could a rapa whelk eat in one year?
