  • Aspects of the social structure of the California ground squirrel (Spermophilus beecheyi) in western Oregon

    Creator:
    Bickford, Carol E.
    Abstract:
    A population of Spermophilus beecheyi was studied to determine patterns of individual spacing, behavioral interactions among different sex and age classes, and the relationship between aspects of S. beecheyi social structure and sociality to those of other sciurids. Research was conducted on a population of squirrels living in an abandoned...

  • 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...

  • 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...

  • The ecological and behavioral dynamics of breeding in three sympatric anuran amphibians

    Creator:
    Olson, Deanna H.
    Abstract:
    Breeding ecology and behavior were investigated in a field study of three sympatric anuran amphibians in the Oregon Cascade Mountains: the western toad (Bufo boreas), the Cascades frog (Rana cascadae) and the Pacific treefrog (Hyla regilla). A comprehensive study of the western toad mating system was conducted at three populations...
