Professor Terry Snell and his laboratory team are investigating mate recognition in zooplankton and the response of aquatic animals to anthropogenic stress. Research efforts focus on identifying genes that are involved in chemical communication between male and female rotifers and genes that are differentially expressed in aquatic invertebrates upon toxicant exposure. A glycoprotein on the surface of female rotifers has been isolated and characterized as a mating pheromone detected by male receptors. In a second project, several genes in stony corals have been identified that are up-regulated upon toxicant exposure. These genes provide information about whether corals have been exposed to toxicants, the level of stress imposed, and the type of stressor present. Professor Snell's laboratory is also examining how pollutants interfere with chemical communication in aquatic animals.
