  • The Effects of Animal Interactions on Zookeeper Attachment and Possible Implications for Animal Welfare

    Creator:
    Koktas, Cemal
    Abstract:
    Human-animal relationships, emerging as an aftermath of human-animal interactions, have been increasingly investigated in recent years. It is possible to see the results of the effects of these relationships on both human and animal welfare. This study predicted that caretakers with hands-on contact with their zoo animals would have significantly...

  • An investigation of the alarm response in anuran amphibian larvae

    Creator:
    Hews, Diana K.
    Abstract:
    The results of my research suggest that tadpoles of the Western toad (Bufo boreas) and the Cascades frog (Rana cascadae) display an alarm response to chemicals from injured conspecific tadpoles. Furthermore, results suggest that the Bufo boreas alarm response can be elicited by a natural predator when it feeds on...

  • Mathematical models of decision processes for dispersing animals

    Creator:
    Brugger, Max F.
    Abstract:
    Each chapter in this expository paper considers a mathematical model of an aspect of animal behavior, and how it affects the patterns of movement across and within a landscape. These models are all directly or indirectly related to questions in either Behavioral Ecology or Landscape Ecology, or both. I first...

  • The effect of rubberized flooring on Asian elephant behavior in captivity

    Creator:
    Meller, Camie L.
    Abstract:
    An experiment was designed to determine the effects of a poured rubber flooring substrate on the behavior of captive Asian elephants. Additionally, room utilization was evaluated in a series of seven rooms used for indoor housing. These seven rooms were divided into two observation areas, the Front observation area which...

  • Applications of GnRH immunization in domestic dogs

    Creator:
    Donovan, Caitlin Elizabeth
    Abstract:
    Reproductive function in the dog is controlled by feedback mechanisms that involve the hypothalamus, the anterior pituitary gland, and the gonads. Surgical gonad removal, a common procedure performed in dogs for the purposes of sterilization, disrupts the hypothalamic-pituitary-gonadal (HPG) axis and results in permanently elevated concentrations of gonadotropins. Manipulation of...

  • Light and the behavior of pelagic animals during night and crepuscular periods

    Creator:
    Wisdom, Daniel W.
    Abstract:
    Light plays an important role in ecological processes in the ocean both day and night. While relatively inexpensive, off the shelf instruments are available to measure Photosynthetically Active Radiation or PAR during the day, efforts to quantify light levels at night have proven more difficult. The goal of this work...

  • Factors influencing diet composition of beef cattle grazing mixed conifer mountain riparian areas

    Creator:
    Darambazar, Enkhjargal
    Abstract:
    Two trials were conducted to evaluate changes in the quantity, quality, and moisture of available forage in the pasture, and shrub utilization by cattle during a 30-d late summer grazing period (Trial 1) and the effect of cow age (experience) on grazing distribution and diet composition (Trial 2) in mountain...

  • Effect of nutrition on reproductive performance of young female mink

    Creator:
    Polonen, Ilpo Juhani
    Abstract:
    Two distinct experiments were conducted. Experiment 1 was conducted to investigate the effects of nutritional conditioning and flushing as a means of improving reproductive performance of female mink. In Exp. 2, vegetable oil and corn syrup were fed during lactation to ascertain whether this nutritional regimen would improve growth of...

  • Exposure to strangers does not cause pregnancy distribution or infanticide in the gray-tailed vole

    Creator:
    De la Maza, Helen M.
    Abstract:
    Numerous laboratory studies with at least 12 species of rodents have reported that exposure of females to strange males results in pregnancy disruption or infanticide. The proximate causes and ultimate benefits of these behaviors have been proposed from an evolutionary perspective. To determine if exposure to strange males or females...
