Service Dogs For Veterans With Ptsd: Taxonomy, Work Stress Reduction, And Matching, Lindsay Parenti 2019 West Virginia University

Service Dogs For Veterans With Ptsd: Taxonomy, Work Stress Reduction, And Matching, Lindsay Parenti

Graduate Theses, Dissertations, and Problem Reports

Research suggests that many veterans with post-traumatic stress disorder (PTSD) struggle with reintegration (Sayer et al., 2010), but are unlikely to seek help or complete treatment (Schottenbauer et al., 2008). To make matters worse, available treatment options are often time consuming, challenging, and/or associated with negative side effects (Carafano & Hutchinson, 2017). Using animals as a treatment modality for veterans with PTSD is an emerging topic of interest and has shown promise (Owen, et al., 2016; Richie et al., 2016). However, several factors have hindered the advancement of this field. Obstacles include a lack of standard terminology and classification system, a need for empirical research to support the effectiveness of animal assisted interventions, and consideration of individual differences in response to animal assisted interventions. This investigation ...

EDUCATIONALCOMMUNITY OUTREACH

by:

Lisa Michelle Tweed

April 2019

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 ...


Effect Of Group Size On The Activity Budget Of Two Captive Chimpanzees (Pan Troglodytes), Kaeley Sullins 2019 Central Washington University

Effect Of Group Size On The Activity Budget Of Two Captive Chimpanzees (Pan Troglodytes), Kaeley Sullins

All Master's Theses

Captive facilities housing chimpanzees are required to provide adequate care and provisions such as dietary, social, and environmental enrichment to promote the psychological well-being of the apes in their care. Chimpanzees are social creatures and changes in groups as well as relocation to a facility with new social partners, can impact each individual chimpanzee’s welfare. By tracking each chimpanzee’s activity budgets, managers can assess welfare and make improvements or adjustments if necessary. I looked at the activity budgets of two captive chimpanzees after the death of a group member and the two chimpanzees’ subsequent relocation to a novel ...


Canis Lupus (Gray Wolf) Pup Survival In Yellowstone National Park, Anne Marie Jehle 2019 University of Montana, Missoula

Canis Lupus (Gray Wolf) Pup Survival In Yellowstone National Park, Anne Marie Jehle

Undergraduate Theses and Professional Papers

The aim of this study was to describe gray wolf (Canis lupus) pup survival rates throughout the summer months in Yellowstone National Park. Understanding pup survival has implications for trends in pack and population age structure, cooperative breeding ecology and other breeding tendencies, social hierarchies, and population fitness, among other elements of species-specific population ecology. A general understanding of trends in pup survival is also relevant to state and federal land that allow gray wolf harvest. Understanding such trends and survival ecology gives managers and biologists the opportunity to evaluate gray wolf populations at a more comprehensive level and implement ...


Effectiveness Of Lure In Capturing Northern Bog Lemmings On Trail Cameras, Keely Benson 2019 University of Montana

Effectiveness Of Lure In Capturing Northern Bog Lemmings On Trail Cameras, Keely Benson

Undergraduate Theses and Professional Papers

Fens and bogs are unique wetlands that support a diversity of small mammals and many other rare species. One such species is the Northern Bog Lemming (Synaptomys borealis). This species is being considered for listing under the Endangered Species Act, so determining their presence is helpful for management. Northern bog lemmings are difficult to trap and when they are caught, experience high mortality rates. Since they are hard to capture and study, it is difficult to determine presence/absence of this species for management purposes. This study used a non-invasive, trail camera method for detecting northern bog lemmings in Finley ...

Elevated Sensitivity To Tactile Stimuli In Stereotypic Horses, Sabrina Briefer Freymond, Déborah Bardou, Sandrine Beuret, Iris Bachmann, Klaus Zuberbühler, Elodie Briefer

Personality Collection

Although stereotypic behaviors are a common problem in captive animals, why certain individuals are more prone to develop them remains elusive. In horses, individuals show considerable differences in how they perceive and react to external events, suggesting that this may partially account for the emergence of stereotypies in this species. In this study, we focused on crib-biting, the most common stereotypy displayed by horses. We compared how established crib-biters (“CB” = 19) and normal controls (“C” = 18) differed in response to a standard “personality” assessment test battery, i.e., reactivity to humans, tactile sensitivity, social reactivity, locomotor activity, and curiosity vs ...

Patterns Of Morphological Plasticity In Metriaclima Zebra And Danio Rerio Suggest Differently Canalized Phenotypes Due To Form-Function Relationships, Dylan Jockel

Masters Theses

In order to ascertain the degree of compatibility in developmental restructuring and behavioral plasticity between two fish species frequently made subject of laboratory research (Metriaclima zebra & Danio rerio), alternative trophic niche exposure experiments utilizing novel three-prong feeding treatments were conducted to obtain morphometric data, which demonstrated both species do bear some degree of plasticity. The results are somewhat complicated by differences in locality of detectable restructuring, which may be due to disparity in the form-function relationship for each species’ lineage. Each is notable in the manner of respective species’ jaw protrusion, as it is driven by anterior kinethmoid rotation in ...
