The Challenges For A Closed-To-The-Public Animal Sanctuary: Prioritizing Animal Welfare While Engaging In Educational Community Outreach, Lisa Tweed Jan 2019

The Challenges For A Closed-To-The-Public Animal Sanctuary: Prioritizing Animal Welfare While Engaging In Educational Community Outreach, Lisa Tweed

All Master's Theses

Chimpanzee Sanctuary Northwest is a small primate sanctuary in Cle Elum, Washington, and is presently home to seven chimpanzees who were retired from biomedical research. I used this sanctuary as a case study to find out how a closed-to-the-public sanctuary can engage in educational outreach without compromising the welfare of the residents. I employed a combination of semi-structured interviews of sanctuary personnel, ethnographic participant-observation as a volunteer caregiver, and an online survey offered to the local community to help me understand the goals and limitations of sanctuaries. I also designed and conducted two educational programs for local area schools as …


Effects Of The Cle Elum Reservoir On The Ephemeroptera (Mayflies) Of The Cle Elum River, David Bruce Ainsworth Aug 1971

Effects Of The Cle Elum Reservoir On The Ephemeroptera (Mayflies) Of The Cle Elum River, David Bruce Ainsworth

All Master's Theses

The purpose of this study was to determine the physical and chemical effects of the Cle Elum Reservoir on the Cle Elum River and to evaluate these effects in respect to the Ephemeroptera of the Cle Elum River. Specific objectives were: (1) To determine the effects of the reservoir on current velocity, volume of flow, turbidity, and temperature. (2) To determine the effects of the reservoir on alkalinity, hardness, dissolved oxygen, and pH. (3) To evaluate the effects of the reservoir on the Ephemeroptera of the Cle Elum River.

An Evaluation Of Three Techniques For The Quantitative Sampling Of Marsh Invertebrates, John T. Falkenbury

All Master's Theses

The present study was designed to develop, compare, and evaluate three methods for quantitatively sampling the invertebrate standing crop on the water surface of dense cattail (Typha latifolia) marshes at 19 sites around the periphery of Caliche Lake in Grant County, Washington.


Preferential Food Habits Of Aplodontia Rufa, Lennis Orville Allen Mar 1969

Preferential Food Habits Of Aplodontia Rufa, Lennis Orville Allen

All Master's Theses

In summary, the findings of this study are that the mountain beaver does exhibit preferences in his food habits. It selects for food just less than one-half of the available plant species. Three species are preferred over all others selected for food, those species being sword-fern, salal, and brake-fern.


The Inadequacy Of Intracranial Stimulation To The Posterior Hypothalamus To Serve As A Reinforcer For Maze Learning In The Rat, John A. Bull Aug 1965

The Inadequacy Of Intracranial Stimulation To The Posterior Hypothalamus To Serve As A Reinforcer For Maze Learning In The Rat, John A. Bull

All Master's Theses

Eighteen, 23 hour food deprived, self-stimulating rats were divided into two groups. One group received 20 ICS pulses as a reward for a correct response in a T-maze while the second group received a food reward. The subjects learned for food over 5 days of 10 massed trials per day, but failed to show learning for ICS either within sessions or over days. There was no difference in learning between rats with high bar press rates and those with low rates in either group.
