Today was the first full day of The Society for Integrative and Comparative Biology (SICB) conference in New Orleans. It was a long day full of great talks and socializing with colleagues old and new over delicious food!
I spent most of the afternoon in the Division of Animal Behavior (DAB) Best Student Presentations, and I heard a number of excellent talks presented by graduate students from around the US and Canada. I’ll highlight a few of the most interesting talks and topics I heard:
Parasites controlling Stickleback behavior – Lucie Grecias, Université Laval
Threespine Stickleback often have a flatworm parasite that is known to influence the behavior of the stickleback to make it less risk averse and more likely to be eaten by wading bird predators (for more on this see THIS LINK). Such parasitic relationships have been described in a number of systems including MICE, and even hypothesized to occur in HUMANS.
These researchers were interested in understanding the mechanistic basis of this behavioral shift. Using a very interesting approach in which the researchers compared parasitized fish to those being dosed with pharmaceutical drugs (including fluoxetine – Prozac) to compare the behavioral responses as well as gene expression in the fish’s brains. While the drugs did replicate some of the behavioral shifts, they did not find similar patterns of gene expression.
Snail Personality and Response to Predation Risk – Chris Goodchild, Oklahoma State University
This was a very cool talk! This research group began by investigating whether snails differ consistently in their behavioral traits (what behavioral ecologists describe as animal personality). Indeed, snails vary consistently in boldness versus shyness, which was measured based on exploration of a novel habitat and latency to open their shell after a disturbance.
They exposed some of these snails to a predator cue to determine how life experience influences their behavior and physiology. After 28 days, the shy snails had developed stronger shells, the openings of which were differently shaped than shy control snails. The researchers hypothesized that when facing a real predator, bold snails move away quickly (by snail standards) after the interaction, while shy snails stay put and wait out the threat.
