We sampled the coffee-bean snail, Melampus bidentatus in four habitats (Spartina patens, tall/creekside S. alterniflora, stunted S. alterniflora, and transitional S. patens) in 8 marshes in the northeast U.S. , including the Plum Island Estuary. Overall, snails were larger in the stunted S. alternilfora and transitional S. patens habitats than in S. patens ones. Only 2 snails were found in the tall S. alterniflora. These data are published in Johnson and Williams 2017 (http://onlinelibrary.wiley.com/doi/10.1002/ece3.3291/full) and refered to as the Regional Study.
All samples collected in June-July 2014. In the field, 10 quadrats (0.0625 m^2) were haphazardly tossed in each habitat (Spartina patens, stunted Spartina alterniflroa, tall Spartina alterniflora and transitional Spartina patens habitats) at each site. All snails within the quadrat were collected and measured for shell length using digital calipers.
