1	A dendroclimatic investigation in the northern Canadian Rocky Mountains, British Columbia Flower, Aquila 30 April 2009 (has links) Subalpine fir (Abies lasiocarpa [Hooker] Nuttall) and white spruce (Picea glauca [Moench] Voss) trees were sampled in an old growth forest in the northern Canadian Rocky Mountains. Dendroclimatological methods were used to analyse the relationship between annual radial-growth and climatic variability. The white spruce ring-width chronology showed stronger sensitivity to climatic variability than the subalpine fir chronology. Both chronologies were positively correlated with growing season mean and minimum temperature. Additionally, the white spruce chronology was correlated with summer maximum temperature, late spring minimum temperature, and diurnal temperature range during the growing season. The subalpine fir ring-width chronology was also correlated with maximum and minimum temperature and diurnal temperature range during the during the previous winter and with the Pacific Decadal Oscillation during each month from December to June. Analysis of the climate-growth responses of individual trees revealed a higher level of intraspecies variability in subalpine fir than in white spruce. The white spruce chronology was selected for use in creating a proxy climate record based on its greater length and stronger sensitivity to climatic variability. Dendroclimatological methods were used to create a regional proxy record of June-July mean temperature extending back to 1772. This reconstruction exhibits a shared pattern of low-frequency variability with other dendroclimatic reconstructions from western Canada and shows no evidence of the recent reduction in sensitivity to climatic variability that is apparent in many other northern spruce chronologies. This study represents the first detailed dendroclimatic analysis undertaken in northern interior British Columbia. This work has elucidated the complex interactions between climate and the radial growth of alpine conifers in the northern Canadian Rocky Mountains. The climate reconstruction presented here fills in one of the remaining spatial gaps in the coverage of annually resolved climate reconstructions in western North America.

3	Tse Keh Nay-European Relations and Ethnicity: 1790s-2009 Sims, Daniel 06 1900 (has links) This thesis examines Tse Keh Nay (Sekani) ethnic identity over three periods of Aboriginal-European relations: the fur trade period, the missionary period, and the treaty and reserve period. It examines the affects these three periods have had on the Tse Keh Nay as an ethnic group in four chapters, the first two dealing with the fur trade and missionary periods, and the last two with the treaty and reserve aspects of the treaty and reserve period. In it I argue that during the first two periods wider Tse Keh Nay ethnic identity was reinforced, while during the latter period local Tse Keh Nay identities were reinforced through government policies that dealt with Tse Keh Nay subgroups on a regional and localized basis. Despite this shift in emphasis, wider Tse Keh Nay ethnic identity has remained, proving that Tse Keh Nay ethnic identity is both situational and dynamic. / History Tse Keh Nay Sekani Ethnicity History Tsay Keh Dene Ingenika Fort Grahame Fort Ware Kwadacha McLeod Lake Takla Lake Bear Lake Fort Connelly Fort Nelson Finlay Forks Adrien Gabriel Morice Alexander MacKenzie Simon Fraser Daniel William Harmon Samuel Black Archibald McDonald John Stuart Treaty No. 8 McLeod Lake Adhesion BC Treaty Process Beaver Dunneza McKenna-McBride Royal Commission Indian Reserve Commission British Columbia Land Claims
