A new first for the Wyeth Lab: a publication as a direct consequence of a conversation at the Canadian Society of Zoologists meeting. We (Shelby Brown [Wyeth Lab alumn] and RCW) have helped out Laura Eliuk and Jillian Detwiler with some video analysis of snail behaviours. The primary result: some interesting changes in how attractive one species of snail is to another species of snail, depending on whether the first snail is infected by a parasite that is also a parasite of the second snail! As you might expect: the parasite seems to make the first host more attractive to the second host. The implication, thus, is host-behaviour modification via a chemical cue! Looking forward to more productive work in this collaboration!
