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...
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...
This thesis seeks to explore how an ecofeminist lens is currently the most useful approach for improving farmed animal welfare. Through examining Western conceptions of non-human animals, I seek to shed light upon the inconsistent treatment of domestic species. Species that are dependent upon us deserve, at a minimum, not...
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...
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...
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...
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...
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...
