Since 2013, Gerardo has carried out much of his fieldwork in Bermuda with two native species of snail, the greater and lesser Bermuda land snails.

自 2013 年以来，Gerardo 在百慕大进行了大量的实地调查，研究的是两种本地蜗牛，大百慕大蜗牛和小百慕大蜗牛。

Lesser Bermuda land snails, as the name suggests, come from Bermuda, but a number of environmental factors have caused the snails to be critically endangered.

小百慕大陆地蜗牛，顾名思义，来自百慕大，但一些环境因素导致这种蜗牛濒临灭绝。

The archipelago's population of land snails—which was once incredibly diverse—has substantially declined, with perhaps 75 percent of more than 750 species now gone.

该群岛的陆生蜗牛种群——曾经极其多样化——已经大幅减少，现在 750 多种物种中大约有 75% 消失了。

Several introductions of damaging insects have been attacked successfully by further introductions of critters that eat them—though this has not worked so well for voracious introduced molluscs called giant African land snails.

通过进一步引入以它们为食的小动物，成功地攻击了几种引入的破坏性昆虫——尽管这对被称为巨型非洲陆生蜗牛的贪婪引入的软体动物来说效果不佳。

In one of his essays, Stephen Jay Gould notes how a hero of his named Henry Edward Crampton spent fifty years, from 1906 to his death in 1956, quietly studying a genus of land snails in Polynesia called Par tula.

斯蒂芬·杰伊·古尔德在一篇散文中指出，他起名为亨利·爱德华·克兰普顿的主人公花了50年时间，从1906年直到l956年去世，不声不响地研究波利尼西亚的一种名叫柄眼蜗牛的陆地蜗牛。
