... in modern aquatic amphibians and the increasing paleontological evidence that the last common ancestor of amphibians and amniotes was aquatic. The vomeronasal system is involved in both foraging and reproductive behaviors in reptiles and has been shown to be involved in some pheromonally mediated behaviors...

... on the behavior or endocrine response of conspecifics. In the domestic pig (Sus scrofa), the steroid androstenone has been identified as a pheromone that facilitates expression of both attraction to the male and a receptive mating stance in estrous females. Though the domestic pig is one of the few vertebrate...

...Neil J. Vickers Shifts in male preference for qualitatively different pheromone blends appear to have played a fundamental role in the divergence of olfactory communication and evolution of moth species. As an initial step in documenting the genetic complexity underlying such shifts, we...

...Neil J. Vickers Pheromone-responsive olfactory interneurons were studied to determine the extent to which their physiological and morphological properties complemented the behavior and peripheral olfactory neurobiology observed in hybrid male moths created by interbreeding two species of heliothine...
