Regional study of Melampus bidentatus lengths in northeast U.S. salt marshes.

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.

本研究在美国东北部包含普拉姆岛河口在内的8处盐沼中，于4类生境下采样了咖啡豆滨螺（Melampus bidentatus），这4类生境分别为：海滨米草（Spartina patens）生境、高大/溪岸型互花米草（Spartina alterniflora）生境、矮化型互花米草生境以及过渡型海滨米草生境。总体而言，矮化型互花米草生境与过渡型海滨米草生境中的滨螺个体尺寸大于海滨米草生境中的个体。仅在高大互花米草生境中发现了2只滨螺。本数据集相关成果发表于Johnson与Williams 2017年的研究（链接：http://onlinelibrary.wiley.com/doi/10.1002/ece3.3291/full），该研究亦被称为"区域研究"。
