Theme overview
The Chemosensory Communication Systems theme encompasses all research on lamprey chemical senses and their role in modulating behavior, physiology, and development. Previous and current research has focused on chemosensory cues that induce neuronal, endocrine or behavioral changes in sea lamprey during the adult phase. Migratory adults orient towards cues released by stream-resident larvae and away from cues released by dead or injured conspecifics. Spawning sea lampreys communicate with pheromones, such as a male pheromone that attracts females to spawning nests and elicits nesting behaviors. Future research will continue to focus on the identity, neuronal processing, and ecological function of chemosensory cues used during migration and reproduction, but may also include chemosensory cues used during other life stages. Studies that address the basic mechanisms and functions of chemosensory cues and pheromones and provide a framework with which they can be mimicked, altered, or disrupted are critical to this research area. Furthermore, studies that directly evaluate the utility of chemical cues to direct, disrupt, or monitor sea lamprey behavior in either adult or larval stages are important for application to sea lamprey control.
