The ability of many domesticated animals to follow human pointing gestures to locate hidden food has led to scientific debate on the relative importance of domestication and individual experience on the origins and development of this capacity. To further explore this question we examined the influence of different prior training...
Domestic dogs’, Canis familiaris, responsiveness to human action has been a topic of scientific interest for almost two decades. However, are all breeds of domestic dog equally prepared to succeed on humanguided object-choice tasks? In the current study we compared three breeds of dog with distinct predatory motor pattern sequences...
Gray wolves (Canis lupus) are the most socially polarizing species listed under the Endangered Species Act. Wildlife management practices at local, state, and federal levels include lethal control to resolve stakeholder and wolf conflicts as a last resort. There is little experimental evidence that lethal control is effective in this...
Following a history of tensions surrounding concubinage in medieval and early modern Spain, the Church sought greater control of religious life, particularly over the sacrament of marriage, via the Holy Office of the Inquisition. The Church exercised its strengthened restrictions and prosecuted these relationships with more frequency, as did civil...
Immunocontraception targeting the zona pellucida shows promise as a safe, effective and economically feasible method for controlling feral horse populations that roam public rangelands throughout the United States. The efficacy of porcine zona pellucida (pZP) vaccines to generate high titers can be evaluated with an indirect immunofuorescence assay or a...
The present study examined involuntary attentional bias toward facial emotion expression. Particularly, the study examined two different attentional components for emotional processing, namely, orienting vs. disengagement. A cueing paradigm using two cue presentation times (250ms and 350ms) was used to determine if attention would be involuntarily captured by an irrelevant...
France's universalistic idea of citizenry has been complicated by a history of colonialism, racialization, and selective acceptance of difference. Although Liberté, Egalité, Fraternité (Liberty, Equality, Brotherhood) is France's motto, the consequences of colonial rule continue to impact the lives of non-autochthonous French citizens today. Since the colonial days, immigrants and...
Continental flood basalts represent short-lived but immense blasts of mafic magma to the continental crust. The youngest and smallest continental flood basalt worldwide, the Columbia River Basalt, initiated with the eruption of the most mafic member, the Steens Basalt (~16.9 Ma). The Steens Basalt is exposed in southeast Oregon, southwest...
This study investigated the local and sustainable food movements in the Willamette Valley of Oregon. The aim of the research was to better understand the current condition of the phenomenon, what it means to the communities studied and the future role it will play in the state. Other research objectives...
An improved understanding of the ecohydrologic relationships in semiarid rangelands is imperative for the development of effective rehabilitation and land management practices. This thesis addresses the ecohydrologic relationships of two significant issues concerning semiarid rangeland ecosystems: western juniper encroachment and increasing stream temperatures.
This thesis is divided into two chapters;...
