I have just returned from the New England Estuarine Research Society meeting in Groton, Connecticut (don’t be jealous). One of my students, Bethany Williams, gave a talk on the coffee-bean snail, Melampus bidentatus, and the effect of sea-level rise. I don’t want to give any spoilers, but as the salt hay in the Great Marsh is lost as sea-level rises, it could be bad news for the snail. But in sunnier news, Bethany, an undergraduate from Florida State University, gave her first talk ever and won best Undergraduate Oral Presentation! Very exciting! Congratulations Bethany!
Below is time-lapse video of snails moving in and out of an abandoned footpath in the marsh. It demonstrates how snails avoid the path during the daytime heat, but when the temperature lowers and the humidity rises they gallop out from the grass to gobble the algae in the open. When the sun (and the heat) returns they ebb back into the grass. It’s a cool video that demonstrates potential impacts of climate change on these, turns out, sensitive snails. When Bethany’s thesis is complete, we’ll post more of the story. For now, enjoy the video.
