Geographic Variation And Behavorial Plasticity: Vigilance In Desert Bighorn Sheep (Ovis Canadensis Nelsoni) Populations, Kathleen Mary Longshore

UNLV Retrospective Theses & Dissertations

Antipredator behaviors such as vigilance are often costly because they must be traded off with other activities, such as feeDing To assess geographic patterns of vigilance behavior in bighorn sheep, I tested the large-scale hypothesis that vigilance in bighorn sheep would differ between populations as a result of spatial heterogeneity in predation regimes. Mean vigilance as well as the covariation of vigilance with environmental factors such as group size and distance from escape terrain were predicted to differ among regions with and without predators. Populations under high predation risk were three populations that had originally been translocated from a mountain …

Late Quaternary Glacial And Periglacial Environments, Snake Range, Nevada, John G Van Hoesen Jan 2003

Late Quaternary Glacial And Periglacial Environments, Snake Range, Nevada, John G Van Hoesen

UNLV Retrospective Theses & Dissertations

Limited research has been conducted on the paleoclimatic significance of glacial and periglacial features in the Great Basin. Glacial features in the range were first recognized and described by early explorers (Gilbert, 1875; Simpson; 1876 and Russell, 1884) and subsequent authors have continued to substantiate and elaborate on earlier reports (Heald, 1956; Kramer, 1962; Currey, 1969; Peigat, 1980; Osborn and Bevis, 2001). Since this early reconnaissance work, few studies have focused on the Late Quaternary evolution and paleoclimatic implications of glacial and periglacial landforms in the Great Basin (Wayne, 1983; Osborn, 1989; Bevis, 1995; and Osborn and Bevis, 2001).

Community College Human Resource Officers' Perceptions Of False Sexual Harassment Accusation Processing, Carlton Ransom Insley Jan 2003

Community College Human Resource Officers' Perceptions Of False Sexual Harassment Accusation Processing, Carlton Ransom Insley

UNLV Retrospective Theses & Dissertations

Sexual harassment in America's academic institutions, including two-year colleges, continues to be an important issue for administrators to address. While people may believe that the potential for false accusations exists, as is true for any inappropriate behavior, little has been written, or presumably, studied about false sexual harassment accusation. A theoretical framework taken from Rotter's Expectancy-Reinforcement Theory (a Social Learning theory) was proposed as a basis to explain the possibility that contemporary conventional behavior may be guiding college administrators who process sexual harassment claims, and those who are participants. It states, in part, that individuals behave in a manner that …
