Norway House: Economic Opportunity and the Rise of Community, 1825-1844.

McKillip, James D. 10 January 2012 (has links)
This dissertation argues that the Hudson’s Bay Company depot that was built at Norway House beginning in 1825 created economic opportunities that were sufficiently strong to draw Aboriginal people to the site in such numbers that, within a decade of its establishment, the post was the locus of a thriving community. This was in spite of the lack of any significant trade in furs, in spite of the absence of an existing Aboriginal community on which to expand and in spite of the very small number of Hudson’s Bay Company personnel assigned to the post on a permanent basis. Although economic factors were not the only reason for the development of Norway House as a community, these factors were almost certainly primus inter pares of the various influences in that development. This study also offers a new framework for the conception and construction of community based on documenting day-to-day activities that were themselves behavioural reflections of intentionality and choice. Interpretation of these behaviours is possible by combining a variety of approaches and methodologies, some qualitative and some quantitative. By closely counting and analyzing data in archival records that were collected by fur trade agents in the course of their normal duties, it is possible to measure the importance of various activities such as construction, fishing and hunting. With a clear understanding of what people were actually doing, it is possible to interpret their intentions in the absence of explicit documentary evidence.

From head to tale : the circulation, display and representation of big-game material culture, c. 1870-1920

Moore, Gillian Lizbeth January 2017 (has links)
Artefacts created from big game material proliferated during the period between 1870 and 1920 and, through their physical and metaphorical circulation as trophies, mementos, furnishings, garments, and personal accoutrements, became increasingly visible as they percolated from their predominantly elite genesis, into a multiplicity of public, domestic and civic spaces. This study seeks to discern the effect of their dissemination, showing how it impacted on the museum displays, domestic decor, fashionable dress and commodity culture of the era. It reflects the extensive representation of big game hunting, and its material effusions, in the text and images of the expanding periodical press, recognising the contribution of published sources to public reception of these artefacts and their developing role as commodities. My thesis aims to demonstrate that detailed examination of the varied and abundant artefacts which stemmed from big game hunting can offer valuable insights into the social and cultural history of the era and argues that this material's entanglement in Britain's imperial project is too significant to overlook. It contends that the transitions from nature to culture, which these objects illustrate, map the reach of the burgeoning Empire, and plot the dichotomies of late Victorian, and Edwardian, engagements with the natural world and subaltern nations. Scholarly work by John M. Mackenzie and Harriet Ritvo, in the mid 1980's, firmly established the relevance of the examination of material culture, within the contexts of animal studies and imperial history, as a fruitful field for academic research, arguing convincingly for further examination of its varied manifestations. However, a generation later, no comprehensive exploration of those elements appertaining to big game hunting has been attempted. Encouraged by the post-millennial 'material turn' in social history, identified by scholars including Bill Brown (2001), Erica Rappaport (2006) and Frank Trentmann (2009), my work draws on a wealth of contemporaneous factual sources including museum, exhibition and trade catalogues, fashion plates, unpublished correspondence, biographical material, museum records, archival sources and popular fiction, to explore the circulation and representation of big game material culture, during a long fin de siècle, and reveal its extensive influence. As a whole, this thesis seeks to offer a nuanced, detailed and holistic view of the visibility and affect of the material culture of big game hunting in the period.

DISTRIBUIÇÃO E OCORRÊNCIA DE PINÍPEDES NA ILHA ELEFANTE, SHETLANDS DO SUL, ANTÁRTICA ENTRE 2005 E 2010 A PARTIR DE CENSOS AÉREOS / DISTRIBUITION AND OCCURENCY OF PINNIPEDS IN THE ELEPHANT ISLAND, SOUTH SHETLANDS ISLANDS, ANTARCTICA, BETWEEN 2005 AND 2010 FROM AERIAL CENSUSES

Trevisan, Mariana Borba 15 May 2015 (has links)
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / Pinnipeds are marine mammals of the Carnivora order. Some species were close to the complete extinction due to predatory hunt for their skin and blubber. Conservation measures have been taken to avoid extinction and population monitoring is essential to evaluate how populations are responding along the years. Remote sensing, from satellite images and aerial photographs, allows the monitoring through individual counting without interfering directly in the animals. The main objective of this work is to analyze aspects of the demography and the distribution of pinnipeds in the Elephant Island, located northeast of the Antarctic Peninsula, in the South Shetlands Islands, during the Austral summer (November to March) in the years of 2005 to 2010, using aerial censuses performed around the Elephant Island. The aerial censuses photographs were taken from Squirrel helicopters of the Brazilian Navy flying at a constant speed, 30 to 50 meters height along the island s perimeter. The data were obtained by counting the individuals registered in the photographs. The counting of all censuses summed 27.592 individuals along the years. Due to the fact that it was not possible to cover the totality of the island s perimeter in all censuses, the distribution and occurrence were studied dividing the island into seven sectors along its total perimeter. In general, the species observed more frequently in all sectors were the Southern elephant seals (Mirounga leonina) and Antarctic fur seals (Artocephalus gazella). Even though other seals species such as the Weddell seal (Leptonychotes weddelli), the leopard seal (Hydrurga leptonyx) and the crabeater seal (Lobodon carcinophaga) registered to the Elephant Island exhibited low representativeness in their occupancy, their presence is constant in all censuses. Using the statistical technique Principal Coordinates Analysis, we notice that the occupancy pattern of the Elephant Island by the pinnipeds is related to the substrate present in the different sectors of the island and to the period of the Austral summer sampled. Southern elephant seals settle in sectors of sandy substrate and exhibit the largest occupation during the earlier months of summer (November and December), while Antarctic fur seals preferably settle in rocky substrates and its occupancy is larger during the latest months of summer (January to February). New breeding sites were described in particular for the Antarctic fur seals in so called sectors of Valentin and Piloto Pardo. Preliminary data taken from satellite images of Valentin sector corroborated the aerial photograph data and indicated that the Antarctic fur seals are the predominant species in this region. To our knowledge, this is the first study taken with aerial censuses data in the Elephant Island, and the results presented here have great use for the correct management and conservation politics for the pinnipeds. / Pinípedes são mamíferos marinhos pertencentes à Ordem Carnívora. Algumas espécies foram levadas quase à extinção devido à caça por sua pele e gordura. Medidas de conservação foram tomadas para evitar a extinção e o monitoramento das populações é essencial para avaliar como estas estão reagindo ao longo dos anos. O sensoriamento remoto através de imagens de satélite e fotografias aéreas permite este monitoramento através da contagem dos indivíduos sem interferir diretamente com os animais. Este trabalho tem por objetivo geral analisar aspectos da distribuição e ocorrência de pinípedes na Ilha Elefante, situada a nordeste da Península Antártica no Arquipélago das Shetlands do Sul, durante o verão austral (novembro a março) entre os anos de 2005 a 2010 através de censos aéreos realizados no entorno da Ilha Elefante. As fotografias de censo aéreo foram tomadas a partir de helicópteros Esquilo da Marinha do Brasil voando em velocidade constante, entre 30 e 50 m de altura ao longo do perímetro da ilha. Os dados foram obtidos através da contagem de indivíduos registrados nas fotografias. Os animais contados a partir dos censos somados atingiram 27.592 indivíduos ao longo dos anos. Devido ao fato de que não foi possível cobrir todo o perímetro da ilha em todos os censos aéreos, a distribuição e abundância foram estudadas dividindo-se a ilha em sete setores ao longo de seu perímetro total. Em geral, as espécies observadas com maior frequência em todos os setores foram os elefantes-marinhos do sul (Mirounga leonina - EMS) e os lobos-marinhos antárticos (Artocephallus gazella - LMA). Ainda que os demais focídeos como a foca-de-Weddell (Leptonychotes weddelli), foca-leopardo (Hydrurga leptonyx) e a foca-caranguejeira (Lobodon carcinophaga) registrados para a Ilha Elefante apresentem baixa representatividade na sua ocupação, sua presença é constante em todos os censos. Utilizando técnica estatística de Análise de Coordenadas Principais, nota-se que o padrão de ocupação da Ilha Elefante pelos pinípedes está relacionado com o substrato presente nos diferentes setores da ilha. Os EMS permanecem em locais de substrato arenoso e apresentam maior ocupação nos primeiros meses do verão (novembro e dezembro), enquanto os LMA permanecem preferencialmente em locais rochosos e sua ocupação é maior nos últimos meses de verão (janeiro e fevereiro). Novos locais de reprodução foram descritos em especial para LMA nos setores denominados de Valentin e Piloto Pardo. Dados preliminares tomados a partir de uma imagem de satélite para o setor de Valentin corroboraram os dados de fotografias aéreas e indica que LMA é a espécie predominante dessa região. Ao nosso conhecimento, esse é o primeiro estudo realizado com dados de censo aéreo na Ilha Elefante e os resultados apresentados aqui tem grande utilidade para o correto manejo e para as políticas de conservação de pinípides.

Análise Morfológica e Ultra-estrutural do Coração do Lobo-Marinho-do-Sul (Arctocephus australis, Zimmermann, 1783) / Morphological and Ultrastructural Analysis of the Heart of the Southern-Fur-Seal (Arctocephalus australis, Zimmermamm, 1783)

Juliana Plácido Guimarães 15 December 2009 (has links)
O lobo-marinho-do-sul pertencente à ordem Carnivora, subordem Pinnipedia e família Otariidae habita ambientes aquáticos e terrestres e, desta forma, apresentando alterações morfofisiológicas adaptativas importantes, entre elas o sistema cardíaco. O coração é o órgão muscular central do sistema circulatório que tem como função o transporte de oxigênio e nutrientes para os tecidos, assim como o transporte de dióxido de carbono. Considerando a importância deste órgão para o funcionamento geral dos demais sistemas corpóreos, este trabalho teve por objetivo descrever a morfologia e aspectos morfométricos do coração a fim de estabelecer comparações entre o coração do lobo-marinho-do-sul com outros pinípedes e carnívoros terrestres. Para tanto, foram utilizados corações de lobo-marinho-do-sul (Arctocephalus australis) que vierem a óbito por causas naturais. Após análise macroscópica e realização de mensurações, os corações foram analisados em nível de microscopia de luz, microscopia eletrônica de varredura, por meio de crio fratura em nitrogênio líquido, e microscopia eletrônica de transmissão. As características topográficas e morfológicas do coração do lobo-marinho-do-sul são descritas. O órgão é quase totalmente envolto pelo pulmão e revestido pelo pericárdio tendo uma forma alongada e achatada. Os aspectos ultra-estruturais apresentaram a disposição de fibras musculares dos átrios e ventrículos com as características típicas de fibras cardíacas revelando os feixes de miofibrilas, mitocôndrias com as cristas mitocondriais nítidas, junções em forma de placas, anastosmoses entre os feixes de miofibrilas e grânulos elétron-densos, nátrio-uréticos, próximo ao núcleo das células musculares ou ao longo da disposição de mitocôndrias das fibras musculares de átrios. / The southern-fur-seal belongs to the order Carnivora, suborder Pinnipedia and Otariidae family lives in aquatic and terrestrial environments and thus presenting important adaptive morpho-physiological changes, between then the cardiovascular system. The heart is the central muscular organ of the circulatory system whose function is to transport oxygen and nutrients to tissues, as well as the transport of carbon dioxide. Considering the importance of this organ to the overall functioning of other body systems, this study was to aim to describe the morphology and morphometric aspects of the heart in order to establish comparisons between the heart of the southern-fur-seals with other pinnipeds and terrestrial carnivores. Therefore, hearts of southern-fur-seals (Arctocephalus australis) were used that come to death by natural pathologies. After macroscopic analysis and execution of measurements, the hearts were analyzed at the level of light microscopy, scanning electron microscopy, using cryo fracture in liquid nitrogen, and transmission electron microscopy. The heart of the fur seal-of-south is surrounded almost entirely by the lung and covered by the pericardium, having long, flat in shape. The ultrastructural aspects presented the dispositive of muscle fibers of the atrium and ventricles under the typical cardiac fibers revelry the myofibrils bundles, mitochondria with mitochondrial cristal, junction in form of plates, anastomosis between the myofibrils bundles, and electron dense granules like natriun-uretriz near to nuclear of muscle cells or along the disposal of mitochondria of the muscle fibers of atrium.

Organização e arquitetura microscópica do sistema tegumentar do Lobo-marinho-sul-americano (Arctocephalus australis, Zimmermann, 1783) / Microscopic organization and architecture of the integumentary system of the South American fur seal (Arctocephalus australis, Zimmermann, 1783)

Ana Paula da Silva 07 November 2008 (has links)
O lobo-marinho-sul-americano (Arctocephalus australis) membro da Ordem Carnivora, é comumente visto nos períodos de outono e inverno na costa brasileira do Rio Grande do Sul até o Rio de Janeiro, porém, sem colônias reprodutivas estabelecidas. A espécie pertence ao grupo dos pinípedes, carnívoros com membros em forma de nadadeiras que vivem em ambiente aquático e terrestre. Estudos sobre a morfologia da pele em pinípedes são raros e antigos, destes procederam muitos relatos divergentes, em virtude da colheita da pele sem referências anatômicas. O objetivo desta pesquisa foi descrever o sistema tegumentar da espécie Arctocephalus australis, utilizando animais que vieram a óbito por causas naturais de uma colônia reprodutiva do Uruguai. As áreas corporais colhidas dorso-ventralmente foram identificadas anatomicamente. Essas regiões foram examinadas por microscopia óptica, segundo critérios histológicos, histomorfométricos, histoquímicos e imuno-histoquímicos nas diferentes estruturas que constituem o sistema tegumentar. A pele do Arctocephalus australis apresentou diferenças entre as regiões de epiderme delgada e espessa. A epiderme delgada apresentou maior quantidade de pêlos do que a epiderme espessa, a qual em algumas regiões era destituída destes. Como os demais mamíferos, a pele do lobo-marinho-sul-americano apresentou glândulas sebáceas, glândulas sudoríparas apócrinas e merócrinas. As nadadeiras apresentaram o maior número de especializações entre as regiões do corpo estudadas, especialmente vinculadas à termorregulação, como o maior volume de glândulas sudoríparas e secções vasculares. Esta pesquisa apontou os aspectos morfofuncionais relacionados à biologia da espécie em ambientes distintos, e esclareceu alguns dados controversos na literatura sobre o sistema tegumentar em pinípedes. / The South American fur seal (Arctocephalus australis) members of the Order Carnivora is usually seen during the autumn and winter season in the Brazilian coast from Rio Grande do Sul to Rio de Janeiro, however, there are no reports of reproductive colonies established. The species belongs to the group of pinnipeds, carnivorous with limbs fin-shaped that inhabits both terrestrial and aquatic environments. Studies of the skin morphology are rare and ancient; these studies have arisen many divergent reports, due to sampling of the skin without anatomical references. The purpose of this research was to describe the integumentary system of the species Arctocephalus australis, using animals that came to death by natural cases from reproductive colonies from Uruguay. The body dorsal and ventral regions were identified anatomically. These regions were examined by light microscopy, according to the histological, histomophometric, histochemical and immunohistochemical criteria in the different structures constituting the integumentary system. The skin of the Arctocephalus australis showed differences between the thin and thick epidermis. The thin epidermis showed larger amount of hair follicles than the thicker epidermis, which in some regions was devoid of hair. As well as the other mammals, the South-american-fur-seal skin showed sebaceous glands, apocrine and eccrine sweat glands. The limbs showed the largest number of the specialization among the regions of the body examined, particularly related to thermoregulation, as well as the largest volume fraction of sweat glands and vascular sections. This research pointed the morphofunctional aspects related to biology of the species in different environments, and elucidated some controversial data in the investigation about the integumentary system in pinnipeds.

From Fur to Felt Hats: The Hudson’s Bay Company and the Consumer Revolution in Britain, 1670-1730

Hawkins, Natalie January 2014 (has links)
This dissertation seeks to explore the wide reaching effects of the ‘Consumer Revolution of the Augustan Period’ (1680-1750) by examining the Hudson’s Bay Company from the perspective of the London metropole. During this period, newly imported and manufactured goods began flooding English markets. For the first time, members of the middling and lower sorts were able to afford those items which had previously been deemed ‘luxuries.’ One of these luxuries was the beaver felt hat, which had previously been restricted to the wealthy aristocracy and gentry because of its great cost. However, because of the HBC’s exports of beaver fur from Rupert’s Land making beaver widely available and therefore, less expensive, those outside of the privileged upper sorts were finally able to enjoy this commodity. Thus, the focus here will be on the furs leaving North America, specifically Hudson’s Bay, between 1670 and 1730, and consider the subsequent consumption of those furs by the British and European markets. This thesis examines English fashion, social, economic, and political history to understand the Hudson’s Bay Company and the Consumer Revolution, and their effects on one another.

Maternal foraging behaviour of Subantarctic fur seals from Marion Island

Wege, Mia January 2013 (has links)
Foraging forms the cornerstone of an animal’s life-history. An individual's foraging success shapes the demography and health of a population. Understanding key facets of maternal foraging behaviour are crucial to get a holistic picture of both regional and local environmental factors that drive foraging behaviour. This study aimed to measure the maternal foraging behaviour of a marine top predator, the Subantarctic fur seal (Arctocephalus tropicalis), from Marion Island (MI) over a range of spatial and temporal scales. Arctocephalus tropicalis females from MI have one of the longest duration foraging trips for the species. They are most similar to conspecifics at temperate Amsterdam Island, but differ considerably from those at subantarctic Îles Crozet and Macquarie Island. Hitherto, no diving data existed for MI females. I illustrate how their diving behaviour is more similar to individuals from Îles Crozet despite their differences in foraging trip parameters. Together with Îles Crozet, MI females have one of the deepest mean diving depths (34.5 ± 2.2 m , 45.2 ± 4.8 m summer and winter respectively) and longest dive durations (70.2 ± 3 s , 104.3 ± 7.8 s summer and winter respectively) for the species. In summer, females follow the diel vertical migration of their myctophid prey. Counter intuitively, during the winter, females performed short and shallow crepuscular dives, possibly foraging on different prey. Considering that these individuals dive in deep waters, this is most likely related to myctophids occupying lower depths in the water column during winter. At dusk and dawn they are inaccessible to diving fur seals. At-sea data from multiple foraging trips per female illustrated that females have both a colony- and individual preferred foraging direction which varied seasonally. Individuals travelled consistently in the same direction regionally, but locally appear to track prey in a heterogeneous environment. The few trips in the winter to the west of MI suggest that this is a short-term response to varying prey availability rather than a long-term foraging tactic. Six years of observer-based attendance cycle data were used to augment telemetry data. Multi-state mark-recapture models were used to determine the probability of a female being missed when she was present (detection probability). Attendance data were corrected accordingly. Neither El Niño (EN) nor anomalous seasurface temperature (SSTa) influenced any of the attendance cycle parameters, as foraging trip duration is a poor predictor of weak environmental change. Only season and pup sex had a significant impact on female provisioning rates. Foraging trip duration was longer during winter than during summer. Females spent a higher percentage of time on land when they had female pups rather than male pups. Although observational attendance data remain useful it ideally requires concomitant data on pup growth, production and female body condition to elucidate changes in female provisioning rates. Temporally, season had the most influence on female foraging behaviour. Spatially, it appears that a lack of prominent local bathymetrical features overshadows MI's favourable position in the productive Polar Frontal Zone. Arctocephalus tropicalis females from MI work harder at foraging than at any other island population of conspecifics. / Dissertation (MSc)--University of Pretoria, 2013. / gm2014 / Zoology and Entomology / Unrestricted
