The geology of the Tracy Canyon area, Saguache County, Colorado
(1976) Newman, James W., author; Thompson, Tommy B., advisor; Burns, Lary K., committee member; Warren, C. G., committee member; McCallum, M. E., committee member
The study area encompasses approximately 30 square kilometers in the Laughlin Gulch and Saguache, Colorado Quadrangles about 13 kilometers southwest of the town of Saguache. Conejos Formation volcanics of the "early intermediate assemblage" as described by Lipman et al. (1970), are mapped as four separate flow units. Pyroclastic rocks, representatives of the second major episode of San Juan volcanism, are absent in the study area. The Conejos Formation volcanics are partially capped by olivine basaltic andesites of the Hinsdale Formation, and represent the "late bimodal eruptive episode." Intrusives in the area represent all of the major volcanic episodes of the northeastern San Juan Mountains. Flows in the study area are commonly tilted gently to the northeast in response to regional deformation associated with development of the Rio Grande block fault system. Faults are expressed as valleys and topographic breaks. They tend to be short or gently curved and follow northeast and northwest trends. Vertical, or steeply dipping faults, commonly bound small horst and graben structures. Many of the faults have histories of recurrent movement, with the latest activity associated with regional crustal extension and development of the Rio Grande Rift. A major northeast-trending lineament, intersecting the Beidell volcanic center, 13 kilometers to the southwest, and the Klondike mining district, 16 kilometers to the northeast, is expressed in the study area by two flow-banded rhyolitic dikes. Hydrothermal alteration extends over an area of approximately 13 square kilometers, centered about an area of small horst and graben structures. A high-silica alteration zone, comprised principally of jasperoid breccias, represents the most intense hydrothermal alteration in the study area. These rocks are irregularly enveloped by an "advanced argillic alteration zone" as defined by Hemley and Jones (1964). Non-brecciated, silicified quartz latites define a third alteration zone. Hydrolytic decomposition of silicate rocks has been interpreted as the most significant hydrothermal alteration process. Hydrothermal alteration and trace metal geochemistry is not consistent with the porphyry ore deposit model (Lowell and Gilbert, 1970), and it is unlikely that a subsurface orebody of this type exists. Therefore, the most likely target for further exploration in the Tracy Canyon area are the jasperoid breccia pipes.

Variation in emperor goose (Anser canagicus) body mass at the geographic extremes of their wintering range
(2025) Scholl, Sophie, author; Aubry, Lise, advisor; Thomas, Robyn, committee member
The emperor goose (Anser canagicus) is a waterfowl species that is endemic to the Bering Sea and holds great ecological, recreational, and cultural value. Emperor geese are unique in their wintering behaviors as they migrate only slightly south of their summer breeding grounds in the Yukon-Kuskokwim Delta to non-breeding wintering grounds that are at relatively high latitudes along the Aleutian Islands, Alaska Peninsula, and the Kodiak Archipelago. Recent declines in emperor goose populations brings to light the importance of developing a more comprehensive understanding of emperor goose ecology, with a particular focus on understanding previously understudied aspects of their wintering ecology. This study explores differences of body mass as a proxy for individual fitness between two wintering sites that represent the geographic extremes of the emperor goose wintering distribution: Shemya Island and the Kodiak Archipelago. A significant difference in body mass between Kodiak and Shemya was observed amongst all adult geese, specifically amongst female adults, with geese on Shemya having lower body mass than the geese on Kodiak in these demographic groups. Additionally, it was observed that variation in body mass among emperor geese could be explained by additive effects of age class, sex, and field site. These findings indicate that differences in environmental conditions, food source availability, and migration distance to the different wintering sites between Shemya and Kodiak could explain why some demographic groups of emperor geese displayed significantly lower body masses, and therefore lower fitness, at Shemya (i.e. longer winter migration, extreme environment, lower access to protein-rich food). Understanding the wintering ecology of emperor geese and dedicating more time and resources to explaining variability in fitness experienced by emperor geese at their wintering sites is critical for understanding how to best move forward with conservation and management strategies that prevent further population declines.

Vertical transmission in the culicoid vector as a possible mechanism for bluetongue virus transeasonality
(1995) Deines, Susan Marie, author; Blair, Carol D., advisor; Beaty, Barry, committee member; Salman, Mowafak, committee member
Bluetongue virus (BTV) is transmitted between vertebrate hosts by arthropod vectors in the genus Culicoides. In tropical and sub-tropical climates the virus is maintained in a continual cycle between the culicoid vector and the vertebrate host; however, bluetongue disease is also enzootic in temperate regions, such as northeastern Colorado. The mechanism by which BTV overwinters in these regions, where the adult culicoid vector does not survive cold winter months, is unknown. The primary objective of this study was to determine if vertical transmission of BTV in the culicoid vector is the mechanism for BTV transeasonality in regions of temperate climate.

Juan Bobo, postcoloniality and Frantz Fanon's theory of violence
(2007) Rodríguez, Enid Sepúlveda, author; Taylor, Cynthia, advisor; Sheidley, William, committee member; Taylor, Ted, committee member
In the postcolonial written adaptations of the oral tales and stories about Juan Bobo political violence is generated against the Jibaros by colonial, postcolonial and neocolonial discourses that are still perpetuated in Puerto Rico through unaltered colonial attitudes, political, socioeconomic structures, institutions and literatures that legitimize the negative perception of the Jibaros as the Other. After 1898, redactors of the written tales of Juan Bobo purged the tales of much of their overt anti-colonial, anti-elitist and subversive implications-the undisguised violence, lies, trickery and resistance to oppression that are so evident in the oral tales. With every subsequent version, Juan Bobo dwindles from trickster to mere tonto (“fool/noodlehead”), making Juan Bobo and the Jibaros he represents objects to laugh at or scorn. Colonial ideologies are evident and inscribed in the texts, in the fact that Juan Bobo seems to always be rescued, saved by a privileged and seemingly benevolent whiter, landowning, and more educated character. These redactions constitute a compromise and betrayal of the authentic Jibaro while deepening the split between Puerto Rico’s elite class and the rural peasantry. They play right into colonialism’s hands.

Ecological literacy in a context of first-year college students
(2003) Bruyere, Brett L., author
This research focused on the knowledge and behavior components of ecological literacy as it pertains to a sample of first-year students at a large land grant university. Specifically, a four-point typology of environmentally responsible behaviors for first-year college students was identified that included dimensions related to consumer, disposal, reuse and conservation activities. The results of the typology were subsequently used to develop attitude and behavior scales to determine the viability of a value-attitude-behavior hierarchy as it relates to environmentally responsible behavior of first-year college students.
