BEHAVIORAL SIGNIFICANCE OF PHEROMONES IN VERTEBRATES

Introduces the concept of pheromones, external chemical secretions having conspecific communication functions, and discusses its significance for vertebrate behavior. The physiological regulatory functions and communication functions of pheromones are distinguished. Physiological regulatroy functions discussed are related to estrous synchrony in females and include the S. Lee-L. M. Boot, W. Whitten, and H. M. Bruce effects. Communication functions discussed include sex attractants, alarm substances, trail substances, territoriality, and individual recognition. The evolutionary significance and research implications of pheromones are also noted. (4 p. ref.)
