Chimpanzee-Caregiver Interactions In Captive Settings: The Effects Of "Cultures" Of Captive Management, Sarah Angela Baeckler

All Master's Theses

Interactions between chimpanzees and human caregivers can have profound effects on both the humans and the chimpanzees. These interactions were studied at three different facilities. Twenty-one chimpanzees and five caregivers were observed during their daily interactions over the course of approximately two weeks per facility. Results indicate differences in the types and styles of interactions that take place at each facility, and the relationships between the chimpanzees and their caregivers.

Implications for captive management were discussed.

Summer Home Range Size Of The Eastern Cascade Mountain Beaver (Aplodontia Rufa Rainieri) In Relation To Availability Of Preferred Food, Robert Julian Stagg

All Master's Theses

Optimal foraging theories relate food preference to nutrient content and nutrient availability to home range size. After synthesizing these theories, I hypothesized that the availability of preferred food plants influences the home range size of generalist herbivores. I also hypothesized that the availability of preferred foods does not affect weight gain of time-minimizing generalist herbivores, but should affect the weight gain of energy-maximizing generalist herbivores. To test these hypotheses, I studied the home ranges, weights, weight gains, food habits, and habitats of six adult female mountain beavers (Aplodontia rufa) from six separate sites where bracken fern was either …

Food Intake In Rats As A Function Of Shock-Avoiding Eating Behavior, Kathleen A. Carlton

All Master's Theses

Consumption of a liquid nutrient by rats under several different circumstances was studied. A restraining apparatus and tailshock were used to train one group to lick a drinkometer tube, creating a forced drinking situation. It was hypothesized that rats in this group would consume significantly more than Ss in the other three groups during a testing phase. The hypothesis was disconfirmed by statistical analysis, though there appeared to be a tendency for avoidance training to produce effective results.

An Investigation Of The Behavior Of Citellus Townsendii Townsendii (Bachman) In Central Washington, Mark Roy Fuller

All Master's Theses

This study of the behavior of Citellus townsendii townsendii was based on field observations of animals at their northern most distribution. The squirrels' seasonal activity and behavioral repertoire, when considered with environmental parameters, suggest important adaptations for survival. The animals were in torpor from about July to February. Activity generally occurred during the midmorning hours, allowing them to avoid temperature extremes. Quantitative analysis of behavioral observations indicated that most activities occurred in a non-random order.

The Breeding Biology Of The Western Tanager (Piranga Ludoviciana), Gary G. Benson

All Master's Theses

In 1969 a two-year study was undertaken in an effort to enlarge our knowledge of the life history of the western tanager (Piranga ludoviciana). Bent (1958) summarizes the literature on the western tanager, and a review of his work clearly shows an almost total absence of detailed information on the species' life history. To obtain this information, observations were conducted from 1 May through 29 July 1969. A few observations were made during the 1968 breeding season.
