Climate change and anthropogenic effects have vastly reduced Westslope Cutthroat Trout (Oncorhynchus clarki lewisi, WCT) habitat throughout their range, including the Colville National Forest in northeastern Washington where this study was conducted. Many native salmonid populations have declined in abundance since the early 1900s due to a variety of climate- and human-driven forces. Westslope Cutthroat Trout are especially sensitive to habitat loss or degradation and to climate change. Together, climate change, habitat degradation, and non-native salmonid invasions are contributing to increasingly fragmented WCT populations. Ongoing and predicted future warming trends are expected to further fragment these populations and isolate them in headwater stream reaches, with populations in the spatial margins of their distributions facing greater risk. Native salmonid populations are often separated or isolated by natural or artificial upstream migration barriers (i.e., waterfalls, culverts, etc.). Prior to continuing conservation and management actions targeting WCT, it is imperative to understand habitat requirements of this keystone species in fragmented areas. Field survey data were collected in the summer of 2015 on channel geomorphic characteristics and WCT presence/absence in 26 streams located in the Colville National Forest. A clear spatial separation was observed between Eastern Brook Trout (Salvenius fontinalis, EBT) and WCT above four culvert road crossings and the habitat in both of these areas was compared statistically to identify explicit differences. This dataset was also analyzed using logistic regression modeling to determine the best habitat predictors of the presence of isolated WCT populations existing upstream of these crossing. In general, stream habitat in the Middle and South Forks of Mill Creek had low large substrate, high fine sediments, and exhibited pool-riffle channel morphology. Pool habitat supporting isolated WCT was significantly smaller, in terms of volume and surface area, than pool habitat supporting sympatric populations of WCT and EBT, largely due to the headwater nature of channel units supporting isolated WCT populations. Additionally, due to the extreme drought conditions during 2015, stream flow was substantially diminished in the study area causing these reaches to be highly fragmented and largely disconnected from the rest of the stream channel. Fine sediments were generally higher in headwater reaches supporting isolated WCT, including in pools and riffles, which was unexpected, mainly because they exist above sediment delivery points in the longitudinal extent of the system. Logistic regression analysis indicated that the presence of isolated WCT populations was primarily positively associated with an increase in large wood and boulders, and negatively associated with increasing gravel, bedrock, habitat unit length, depth, and width (Significant x2, R2=0.174, misclassification rate = 14.9%, α=0.05). The final model correctly predicted 37.5% of isolated WCT presence observations and 96.5% of the WCT/EBT presence observations significantly better than by chance alone (k=0.81). This model, in fact, may be useful in identifying limited habitat due to the fragmented nature of the channel units supporting IWCT. Large wood and boulders were positively correlated to WCT presence, likely because both are important in the formation of pools and cascades. Channel unit length, width, depth, active channel width as well as gravel and bedrock substrates, were all negatively associated with WCT presence. This suggests that isolated WCT are primarily associated with small headwater cascades with complex shelter, which may provide greater thermal and predation refuge compared to shallow glide or large pool habitats. Future model analysis should include additional habitat variables such as water temperature, stream gradient, and species interactions to strengthen the prediction of Westslope Cutthroat Trout presence. Overall, I concluded that differences in stream habitat above and below blocking culverts are not driving Westslope Cutthroat Trout distributions in the study area due to confounding factors such as the presence of problematic barriers and small sample size. I also conclude that future conservation and management decisions specific to WCT should prioritize complex cascade habitat in headwater stream reaches because of the type and quantity of habitat they may provide, especially during severe drought or low flow conditions.

High Arctic permafrosted soils represent a massive sink in the global carbon cycle, accounting for twice as much carbon as what is currently stored as carbon dioxide in the atmosphere. However, with current warming trends this sink is in danger of thawing and potentially releasing large amounts of carbon as both carbon dioxide and methane into the atmosphere. It is difficult to make predictions about the future of this sink without knowing how it has reacted to past temperature and climate changes. This dissertation summarizes the results of the first study to look at long term, fine scale organic carbon delivery by the high-Arctic Colville River into Simpson’s Lagoon in the near-shore Beaufort Sea. Modern delivery of organic carbon to the Lagoon was determined to come from a variety of sources through the use of a three end-member mixing model and sediment biomarker concentrations. These sources include the Colville River in the western area of the Lagoon near the river mouth, marine sources in areas of the Lagoon without protective barrier islands, and coastal erosional sources and the Mackenzie River in the eastern area of the Lagoon. Downcore organic carbon delivery was measured on two cores in the Lagoon, one taken near the mouth of the Colville River (spans about 1800 years of history) and one taken on the eastern end of the Lagoon (spans about 600 years of history). Bulk organic parameters and biomarkers were measured in both cores and analyzed with Principle Component Analysis to determine long-term trends in organic carbon delivery. It was shown that at various times in the past, highly degraded organic carbon inputs of what is likely soil and peat carbon were delivered to the Lagoon. At other times, inputs of fresher, non-degraded, terrestrially-derived organic carbon inputs of what are likely higher amounts of plant and vegetative material was delivered to the Lagoon. Inputs of degraded soil carbon were also shown to correspond to higher temperatures on the North Slope of Alaska, likely indicating that warmer temperatures lead to a thawing of permafrost and in turn organic carbon mobilization to the coastal Beaufort Sea.

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / This Dissertation has as its objective a study of the teaching of English in military training, especially in the Military Academy of the court of Rio de Janeiro. The work has the timeframe from 1810 to 1832. The year 1810 was chosen as the starting point because on December 4th, the Royal Military Academy was created by King John VI, expressed in the Charter Act. It contained all the fundamental aspects for the proper functioning of the Academy, which included the teaching of English, French or German, where the military junta thought necessary. But the final milestone of the research was established in 1832, because it was the year in which, there was a change in the military status and the teaching of foreign languages is no longer required. The Dissertation, at first, will address the issues that led the Portuguese to take an interest in learning the English language. In a second step, it will address the importance of modern languages - English and French - for the training of military, since the military books and some of the Portuguese army officers were foreigners. Finally, the text will address some aspects of the teaching career of Eduardo Thomaz Colville, first and only English teacher of the Royal Military Academy of the researched period. The results obtained from the research was that the English language, together with the French, was essential for understanding of military books that were in foreign languages, therefore without this knowledge, the soldiers would be unable to perform their duties and receive promotions. In the construction of the dissertation were used various scientific character of works, such as books, theses, dissertations, papers, articles, manuscripts and journals. / A presente Dissertação tem como objeto de estudo o ensino de inglês na instrução militar, sobretudo na Academia Militar da corte do Rio de Janeiro. O Trabalho tem como marco temporal o período de 1810 a 1832. O ano de 1810 foi escolhido como marco inicial porque no dia 4 de dezembro deste ano foi criado a Real Academia Militar por ordem de D. João VI, expressa em Carta de Lei. Nela constavam todos os aspectos fundamentais para o bom funcionamento da Academia, o que incluía o ensino da Língua Inglesa, Francesa ou Alemã, caso a Junta Militar achasse necessária. Já o marco final da pesquisa foi estabelecido em 1832 porque foi neste ano que ocorreu uma mudança no estatuto militar e o ensino das Línguas Estrangeiras deixou de ser exigido. A Dissertação, em um primeiro momento, tratará dos aspectos que levaram os portugueses a se interessarem pelo estudo do idioma inglês. Em um segundo momento, ela tratará da importância das línguas vivas inglês e francês para a capacitação dos militares, uma vez que os livros militares e alguns dos oficiais do exército português eram estrangeiros. Por último, o texto abordará alguns aspectos da trajetória docente de Eduardo Thomaz Colville, primeiro e único professor de inglês da Academia Real Militar do período pesquisado. O resultado obtido com a pesquisa foi que a Língua Inglesa, juntamente com a Francesa, foi essencial para compreensão dos livros militares que se encontravam em línguas estrangeiras, pois sem esse conhecimento os soldados estariam inaptos para exercerem as suas funções e receberem promoções. Na construção da Dissertação foram utilizadas diversas obras de caráter variado, tais como livros, teses, dissertações, documentos, artigos, manuscritos e revistas.

The present study has as its objective a biobliographic research of English teachers who contributed to English language teaching in our country in their corresponding institutional contexts. In this sense, we followed the path which led to the construction of the European national ideal, whose underlying assumption was the institution of a national language. In addition, it timidly began during the Enlightenment and was consolidated in the nineteenth century. Moreover, we established the correlation between schooling and the process of teaching professionalization in the eighteenth century, taking into account the Portuguese- Brazilian case, which Pombal s reforms was the basis of laws dispatched during Brazil s empire. Furthermore, we analysed the trajectory of English language in Brazil through the legislation, the selection of the most representative grammars and dictionaries and the role performed by translators and interpreters in the process of affirmation of English language in Brazil. At last, we narrated the professional trajectories of the first English teachers in our country, Eduardo Thomaz Colville, John Joyce and Guilherme Paulo Tillbury, in the condition of Enlightenment intellectuals as well as responsible for the affirmation of that profession as well as English language during the nineteenth century in Brazil. / O presente estudo teve por objetivo geral fazer um levantamento biobibliográfico de professores de língua inglesa que, em seus respectivos contextos institucionais, contribuíram para o desenvolvimento do ensino daquela língua em nosso país. Nesse sentido, enveredamos pelos caminhos que levaram ao ideário nacional europeu, que teve como pressuposto subjacente a instituição da língua nacional e foi iniciado no contexto da Ilustração e consolidado no século XIX. Outrossim, estabelecemos a correlação entre a forma escolar e o processo de profissionalização docente no século XVIII, considerando em particular o caso luso-brasileiro, no qual as reformas pombalinas lançaram as bases de Leis expedidas na época do Brasil Imperial. Destarte, analisamos a trajetória da língua inglesa no Brasil através da legislação, da seleção de gramáticas e dicionários mais representativos e do papel dos tradutores e intérpretes no processo de afirmação daquela língua em território brasileiro. Por fim, narramos as trajetórias biobliográficas dos primeiros professores de inglês no Brasil, a saber: Eduardo Thomaz Colville, John Joyce e Guilherme Tillbury, na condição de intelectuais ilustrados, responsáveis pela afirmação daquela língua no Brasil oitocentista.

Over the past half century, the USDA Forest Service has increasingly faced diverse and often competing demands for forest resources, ranging from recreation, to ecosystem services, and timber supply. Building positive community-agency relationships has become increasingly important. Such relationships can improve community support for forest planning and management activities, ultimately making the agency more efficient and effective, while also providing economic and social benefit to local communities. The development of social capital may play an important role in promoting positive agency-community relationships. Broadly defined, the term refers to the social networks between individuals and groups that create a willingness and ability to act collectively toward a common goal. This study focuses on the impact that a partnership between the Colville National Forest and Northeast Washington Forestry Coalition has had on rural Northeast Washington communities. Overall, our study suggests the partnership has positively impacted networks among community members and networks between the community and the Forest Service. However, there is room for improvement. Many study participants were not familiar with important details about the Coalition's membership and objectives, or how its work may impact them or their community. Targeted outreach efforts will likely lead to greater support for the partnership. Such efforts could also strengthen networks among community members and community-agency networks as individuals learn how the partnership can benefit them and issues they care about. / Graduation date: 2012
