  • Activation, modification and suppression of sex pheromone production in garter snakes

    Creator:
    Parker, M. Rockwell
    Abstract:
    Vertebrates communicate with one another and coordinate intraspecific reproduction by using a variety of sexually dimorphic signals, such as plumage, ornaments, sounds, and/or scents. These sexual dimorphisms are maintained by physiological factors, typically sex-specific hormones (though see Chapter 3 for an exception). The purpose of the research in this dissertation...

  • Pheromonal mediation of reproductive behavior in the brown tree snake

    Creator:
    Greene, Michael John
    Abstract:
    In animals, reproductive behaviors serve to attract individuals together during the breeding season and to coordinate the behavioral and physiological states of individuals so that mating can successfully occur. In snakes, the various reproductive behaviors including courtship, mating, courtship inhibition, male combat and trailing are mediated primarily by pheromones. Pheromones...

  • Stress and reproduction in male garter snakes

    Creator:
    Moore, Ignacio T.
    Abstract:
    Animals respond to stressful situations with increases in plasma levels of glucocorticoid stress hormones. These hormones originate from the adrenal cortex in response to stimulation of the hypothalamic-pituitary-adrenal axis. Glucocorticoids (corticosterone in reptiles) function to mobilize energy and suppress unnecessary functions until the stress passes. Among these immediately unnecessary functions...
