NOAA's Coral Reef Conservation Program (CRCP) Acropora palmata snail corallivore removal evaluation in the Florida Keys from 2011-2013 (NCEI Accession 0161266)

This data contains visual observations as well as Predatory snail removal and analysis on several reef plots in the Florida Keys. During the initial removal in June 2011, 639 snails were removed from twelve 150m2 plots. Snails were removed 2 additional times during a seven month removal phase, and then counted at five surveys over the next 19 months to track recolonization. At the conclusion, snails were collected, measured and sexed.

本数据集涵盖佛罗里达礁岛群（Florida Keys）内多个珊瑚礁样地（reef plots）的视觉观测资料，以及针对捕食性蜗牛（Predatory snail）的移除实验与配套分析。2011年6月开展首次移除作业时，研究人员从12个面积为150平方米的珊瑚礁样地中共移除639只该类蜗牛。在为期7个月的移除阶段内，研究人员额外进行了2次蜗牛移除操作；随后在后续19个月间开展5次调查计数，以追踪蜗牛的种群重新定殖情况。实验收尾阶段，研究人员对采集到的所有蜗牛完成了形态测量与性别鉴定。
