The Coquihalla Volcanic Complex consists of calc-alkaline acid to intermediate extrusive and intrusive rocks which have an areal extent of roughly 30 km2, near Hope, British Columbia. The oldest and most voluminous members of the complex are rhyclitic pyroclastic rocks (variably welded lithic-crystal lapilli tuff, vitric tuff, and crystal-lithic lapilli tuff) , that have an overall thickness of approximately 1600 m. Later igneous activity produced numerous andesite to dacite domes, dykes, and sills- A late stage diorite to quartz-diorite stock forms the core of Coquihalla Mountain. Most pyroclastic rocks rest unconformably en the Jurassic to Cretaceous Eagle pluton. Monolithologic avalanche breccias formed in the southern portion of the map area, where pyroclastic recks were deposited against a fault scarp with uplifted Lower Cretaceous Pasayten Group rocks. In the southeastern part of the area, monolithologic avalanche breccias formed in response to tilting and uplift of the underlying Eagle pluton as the basin subsided. All tuffaceous rocks are characterized by vitroclastic textures, and contain phenocrysts of plagicclase (An 40-20), biotite, quartz, and minor potassium feldspar and titanomagnetite. Andesites are porphyritic with phenocrysts of plagioclase (An 76-30), calcic augite, magnesic- to tschermakitic hornblende, and titanomagnetite. Glomeroporphyritic clots consist of plagioclase, aluminous augite, and titancmagnetite. Porphyritic dacites contain phenocrysts of plagioclase(An 60-35), hornblende, titanomagnetite, and minor apatite. The diorite stock consists of orthopyroxene^ clinopyroxene, plagioclase, titanomagnetite, and ilmenite, with interstitial quartz and potassium feldspar. Three K-Ar dates average 21.4±0.7 Ma, and are concordant with a Eb-Sr isochron (22.3±4 Ma with initial 87Sr/86Sr = 0.70370±0.00008) based on seven whole rock sauries which span the entire compositional range of the suite. These results indicate that the Coquihalla Volcanic Complex is coeval with calc-alkaline centres in the Pemberton Volcanic Belt. The whole rock compositions of members of the Coquihalla Volcanic Complex show a range in silica contents from 54 to 76 weight per cent (volatile-free). In relation to increasing silica content, chemical variations within the suite are characterized by enrichment of K₂0, Na₂0, Rb, and Nb, and depletion in Al₂0₃, Ti0₂/ MgO, MnO, CaO, P₂O₅, Cr, Ni, V, and Sr. The elements Ba, Ce, Nd, and Zr show enrichment throughout most of the suite, but depletion in the most felsic members. Interpretation of chemical variations of whole rocks and constituent phenocrysts suggests that the chemical diversity of the suite is governed by fractional crystallization. The results of quantitative major and trace element modelling indicate that 1) hornblende dacites can be derived from basaltic-andesites by 50% crystallization of a mixture of plagioclase, hornblende, clinopyroxene, titanomagnetite, and apatite, and 2) rhyolites can be derived from dacites by roughly 45% crystallization of a mixture of plagioclase, hornblende, biotite, titanomagnetite, and apatite. Basaltic andesite compositions are consistent with derivation from basaltic liquids (modified by olivine fractionation) that are produced by partial melting of hydrous mantle peridotite above the subducted Juan de Fuca plate. / Science, Faculty of / Earth, Ocean and Atmospheric Sciences, Department of / Unknown

The aim of master thesis is the design of full suspension mountain bike frame for racing and competition use. The base of the design solution is selection optimal conception of suspension which influence external design of the frame. General benefit of this concept is utilizing specific properties of carbon composite for design of funkcional frame parts and their technical and visual integration. Important part of this work is design of frame details: rear ends, rear shox's link and duct of the bowdens, wires and brake hydraulic housing.

That the tick, Dermacentor andersoni Stiles, was the vehicle of transmission for the disease Rocky Mountain spotted fever was first suggested by Wilson and Chowning (1902). The disease itself has been recognized since 1873, being first known from the Bitter Root Valley of Montana. The first medical record, however, was reported from Idaho by Wood (1896).

Global biodiversity is in decline as a result of unprecedented human alterations to the earth’s land cover. Understanding the ecological mechanisms of these large-scale changes in biodiversity is imperative in furthering our knowledge on the effects these alterations may have on animal behaviour and consequently on populations, allowing researchers and managers to effectively conserve species. During the last decade, there have been reports of moose populations both increasing and decreasing in North America due to a variety of factors (e.g., climate change, habitat disturbance, disease, etc.). Within British Columbia, wildlife managers have reported moose population declines of up to 50 – 70%, while other areas have remained stable. These changes have coincided, spatially and temporally, with the largest recorded mountain pine beetle (Dendroctonus ponderosae) outbreak. The outbreak resulted in extensive logging and road building in attempts to recover economic value from the beetle killed trees, resulting in drastic changes to the landscape. Understanding the effects that a highly disturbed landscape has on a species is critical for effective management and conservation. To investigate this, I examined the seasonal response of female moose to landscape change caused by the Mountain Pine Beetle outbreak and attendant salvage logging infrastructure in the Interior of British Columbia on the Bonaparte Plateau. First, I used a cluster analysis framework to develop biologically relevant seasons for female moose using individual movement and habitat use. I then used this temporal framework to develop seasonal home ranges for each individual moose. Second, I modeled the seasonal habitat selection of female moose to examine how moose respond to salvage logging infrastructure (i.e., dense road network and extensive cutblocks) using resource selection functions in an information-theoretic framework. We tested whether predation risk, forage availability or the cumulative effects of salvage logging best predicted moose space-use. Moose movement data clustered into five biologically relevant seasons, which were consistent with our biological and ecological knowledge of moose in the study area; however, these seasons and the size of the range differed from other seasons defined using alternative methods in the region. Across all seasons, the cumulative effects of forage availability and risk best predicted female moose distribution. In the calving and fall seasons, the top risk model best predicted moose habitat selection while the top forage availability model better explained moose habitat selection in spring, summer, and winter. Our results identified the importance of defining biological seasons using empirical data and how these seasons can differ from arbitrarily defined seasons, as well as the implications these can have in subsequent analysis and management. Additionally, we found that moose are seasonally trading the benefits of foraging for predation risk in these highly disturbed landscapes, using some aspects of salvage logging. My results bring perspective on how moose are using a highly disturbed landscape at the seasonal scale and a nuanced approach to landscape management. / Graduate

The Mountain Meadows Massacre is widely considered to be the most violent and controversial event in Utah’s history. This qualitative study investigates how the massacre has been portrayed to Utah’s schoolchildren through the state’s history and social studies curricula, and why curricular narratives of the massacre have changed with time. The study presents a content analysis documenting changes in curricular narratives of the Mountain Meadows Massacre from the years 1908-2011. The content analysis also compares these narratives with four concurrent sources providing narratives of the massacre: (a) public monuments commemorating the massacre, (b) curricular narratives published by Utah’s dominant religious and cultural institution—The Church of Jesus Christ of Latter-day Saints (LDS or Mormon Church), (c) Paiute Indian narratives of the massacre, and (d) scholarly histories. Using a continuum of Mormon/Paiute culpability as a frame of reference, this research employs literatures from the theory of ideology in curriculum, multicultural education theory, postcolonial theory, and Mormon historiography to provide critical analysis of changes in narratives of the massacre. Data drawn from this analysis are used to answer the following question: What factors have contributed to changes over time in how the Mountain Meadows Massacre has been portrayed in Utah’s public school curricula? The response to this question provides a basis for discussing and understanding the relationship between hegemony and curriculum in Utah society.

This thesis is a study of the geology of the southeast quarter of the Bone Mountain Quadrangle. The bedrock geology mapped includes about 56 square miles.The Klamath Mountain and Coast Range Provinces of southwestern Oregon are represented in the area. Rocks in the area include the Rogue, Dothan Riddle, Days Creek, upper member of the Umpqua and Tyee Formations. The ages of these rocks range from Late Jurassic to middle Eocene. Late Jurassic ultramafic and mafic intrusive rocks associated with the Rogue Formation occur in the Klamath Province. The metavolcanics of the Rogue Format ion and an associated linear belt of mafic intrusive rocks have been thrust northwestward over the Late Jurassic-Early Cretaceous Riddle Formation. Ultramafics occur along the fault. Graywackes, siltstones, and conglomerate lenses of the Dothan Formation have been downfaulted relative to the Rogue Formation along a southeasterly dipping fault. The Dothan Formation is steeply dipping to the southeast and contains numerous folds inclined to the northwest. The genetic relationships of faulting are problematic. The Myrtle Group conglomerates, siltstones and sandstones are greatly folded and dip to the northwest. Internal structures are intense and diagnostic fauna of Late Jurassic to Early Cretaceous age indicates separate lithologic units of shallow water deposition. Tertiary sedimentary rocks include the upper member of the Umpqua and Tyee Formations of middle Eocene age. The formations are gently dipping to the northwest with coal beds and fauna indicating a near shore depositional environment.

The most elevated point in the United States is Mount Whitney. Many citizens in the United States. know this. But. what more do they know of it? Some guess that it is in t -he Sierra Nevada Mountains, some vaguely realize that it is in California, but how many know of the role Mount Whitney has played in the development of science, history and literature of the west and of the nation?

The Mountain Gorillas of Central Africa are one of the most highly endangered species in the world, with only 740 individuals surviving. One of the greatest threats to this species is disease. Health of wildlife is continually garnering more attention in the public arena due to recent outbreaks of diseases such as West Nile and High Pathogenic Avian Influenza. However, no system currently exists to facilitate the management and analysis of wildlife health data. The research conducted herein was the development and testing of a health information monitoring system for the mountain gorillas entitled Internet-supported Management Program to Assist Conservation Technologies or IMPACT?. The system functions around a species database of known or unknown individuals and provides individual-based and population-based epidemiological analysis. The system also uses spatial locations of individuals or samples to link multiple species together based on spatial proximity for inter-species comparisons. A syndromic surveillance system or clinical decision tree was developed to collect standardized data to better understand the ecology of diseases within the gorilla population. The system is hierarchical in nature, using trackers and guides to conduct daily observations while specially trained veterinarians are used to confirm and assess any abnormalities detected. Assessment of the decision tree indicated that trackers and guides did not observe gorilla groups or individuals within groups similarly. Data suggests that, to be consistent, trackers and guides need to conduct observations even on the day that veterinarians collect data. Validity and reliability remain to be tested in the observation instrument. Assessment of pathogen loads and distributions within species surrounding the gorillas indicates that humans have the greatest pathogen loads with 13 species, followed by cattle and chimpanzees (11), baboon (10), gorillas (9), and rodents (3). Spatial aggregation occurred in Cryptosporidium, Giardia, and Trichuris; however, there is reason to question the test results of the former 2 species. These data suggest that researchers need to examine the impact of local human and domestic animal populations on gorillas and other wildlife.
