This dissertation begins in 1821, when the Hudson's Bay Company took over the Columbia Department from the North West Company, which since 1813 had exported a single commodity (peltries) from the watersheds of two great rivers (the upper Fraser and lower Columbia) to two markets (London and Canton). This fur trade appeared at first so unpromising that the Hudson's Bay Company considered abandoning the lower Columbia region in 1821. Instead of doing so, between 1821 and 1843, the Hudson's Bay Company consolidated its operations in the Columbia Department through the application of a number of venerable commercial policies of the Canadian fur trade. The company extended its fur trading activities to all the major rivers of the region, from the Taku in the north to the Sacramento in the south. To support this massive trade extension the company developed large-scale provision trades in agricultural produce and salmon on the lower Columbia and Fraser rivers. Environmental and cultural conditions favoured these developments. The company also took advantage of the possibility of seaborne transport to develop markets at Oahu (Hawaii), Yerba Buena (San Francisco), and Sitka. To these places the company exported, on its Pacific fleet of ships, a range of country produce from the west coast, especially lumber and salmon. By 1843 the company had developed a new regional economy based on local commodities and Pacific markets; fur continued to be sent to London on an annual vessel. These new exports, and this new regional economy, depended on Native labour in addition to a permanent non-Native workforce of about 600. The company in several places colonized the Native economy and redirected its produce to foreign markets. In 1843 the trade in fur remained—despite the emergence of profitable new export trades—the company's major source of profit from the Columbia Department. The dissertation ends in 1843 when, fearing the possibility of an unfavourable boundary settlement, the company established Fort Victoria to serve as new departmental headquarters, at the same time inaugurating a considerable northward realignment of company activities on the Pacific. At this new post the fur trade would be a minor activity; company officials intended to develop a wide range of resources on Vancouver Island, all of them involving the hiring of Native workers. Increasingly, with the help of Native labour and trade, the company embarked on policies of resource development and extension of commerce on the coast, while the interior districts produced only fur. Difficulties of transport and distance from market prevented similar developments in the company's districts east of the Rocky Mountains.

Divergent values and. approaches to land and resource use and fur conservation created conflicts between aboriginal and non- aboriginal peoples which have remained largely hidden in historical records. This study of the compulsory trap line registration system implemented in British Columbia in 1925 examines these conflicts; the jurisdictional arid administrative issues related, to fur conservation that contributed, to the disputes; and the First Nations objections to fur management schemes that validated white appropriation of traditional lands and restricted traditional vocations and access to important sources of food.' supplies. Although First Nations people spoke persuasively about aboriginal rights and justice, their voices remained largely unheard and. unheeded. Legally disempowered and without political support, First Nation's people were marginalized, removed from lands they had occupied and used, since 'time immemorial.'

Prior investigations in the early contact era have not extensively analyzed the Miami Indian tribe. This time period offers a classic interaction between a pre-industrial economy and a more advanced industrial economy. The vehicle linking the Miami economic system with the European system was the far reaching fur trade. This investigation was undertaken to examine the impact of the European fur trade upon the Miami Indian economic system and subsequently the Miami Indian culture. The economic system was the most influential component in the Miami culture during that time period. Changes to other cultural components were directed through the changing Miami economic system. The changes to the Miami culture during the latter half of the seventeenth century helped establish a foundation for later Miami Indian cultural changes, which occurred in the eighteenth and nineteenth centuries.

This is an evaluation of the contribution of the Australian Aboriginal collection in the Museum fur Volkerkunde in Berlin to the current public perception of Aboriginal cultural identity both in Berlin and wider afield. It gives an account of the collection including the origins and the nature of the objects and some of the key people who have contributed to its assembly and its presentation since the Museum’s foundation. This provides evidence of significant scientific and cultural links between Australia and Germany from the earliest times of white settlement and exploration in Australia. It also reveals how the period of active collection of Australian Aboriginal material in the Museum coincided with the activities of several key collectors within Australia who have been more widely appreciated in Australia for their other achievements in the sciences or the arts. / Assessed within a broad social and an historical context, why and how the collection was assembled, categorised, presented and received by scientists and the public over the years contributes to appreciating its role in the historical construction of a German view of Australian Aboriginal cultural identity. At the same time, the nature of institutional classifications of such cultural material is shown to contribute to the perceived gap in production of authentic Aboriginal art during the twentieth century within the Western account of art history. A comparative analysis of this information relative to other significant museum collections and presentations of Australian Aboriginal material in Germany, the UK, France and Australia contributes to a re-evaluation of the Berlin collection within a contemporary frame of reference involving both science and art. / This work leads me to recommended changes to the management and presentation of the collection of Australian material that is cognisant of the traditional scientific status of the Museum while introducing new museological strategies. It includes devising new programs of activity related to the collection that will be appropriate to its historical context while having contemporary relevance both to the institution, its wider institutional context and especially to the contemporary Australian Aboriginal communities who have links to the collection.

A recognition system is required between pinniped mothers and pups. For otariids this is especially important since females frequently leave their pups for foraging and must reunite on return. Pups must deal with these fasting periods during maternal absence and consequently may attempt to obtain allomaternal care from unrelated females. This research on the New Zealand fur seal (Arctocephalus forsteri) at Ohau Point, Kaikoura, New Zealand, quantified mother-pup recognition behaviour during reunions, individuality of pup calls used by mothers to recognise their pup, and the occurrence of allosuckling as a possible recognition error by females and as a strategy employed by pups to gain allomaternal care during their mothers' absence. A combination of behavioural observations, morphometry, VHF radio telemetry, acoustics and DNA genotyping were employed to study these topics. Postpartum interaction behaviours between mothers and pups appeared to facilitate development of an efficient mother-pup recognition system, involving mainly vocal and olfactory cues that were utilised during reunions. Greater selective pressure on pups to reunite resulted in an asymmetry of searching behaviour between females and pups during reunions. The vocalisations of pups were stereotypic, especially those features of the fundamental frequency and frequency of the lowest harmonic, which are likely to facilitate recognition of a pup by their mother. Pups attempted to steal milk from unrelated females more often during maternal absence and appeared to modify the intra-individual variation pattern of a feature of their vocal signatures over this period, which may assist attempts at allosuckling under nutritional stress. Fostering was demonstrated to occur despite costs to filial pups and possible costs to female reproductive success and may be attributed to development of erroneous recognition between females and non filial pups, or kin selection. This study provides a valuable contribution to the knowledge of recognition systems between pinniped mothers and pups, of alternative pup strategies under nutritional stress and of the rare occurrence of fostering in otariid pinnipeds.

Colony dynamics, maternal investment, and indicators of health were investigated for the New Zealand fur seal (Arctocephalus forsteri) over four austral summers, 2001- 2005. Effort was focused at the Ohau Point seal colony, north of Kaikoura. Two colonies at Banks Peninsula were included for comparisons of colony growth and pup condition. A range of other colonies were also included for making comparisons about colony dynamics and health indices. Colony dynamics were investigated through mark-recapture estimates of pup production and daily census of all individuals at the Ohau Point colony. Maternal attendance patterns were observed through behavioural observations of known females (n = 120), the use of VHF radio transmitters (n = 33), and female mass and body condition estimates (n = 51). Maternal investment was also investigated through longitudinal sampling of pup mass and growth rates. Parameters used to indicate colony health were: body condition, growth, presence of parasites, and the levels and common causes of mortality. The influence of parasites on pup growth was tested using treatment of selected pups with Ivermectin anti-helmentic medication, and mortality in the region was investigated through reports of dead individuals, and post mortems of those found fresh. The Ohau Point colony is in an exponential state of growth, and pup mass and condition was higher and responded to changes in environmental variables differently than at the Banks Peninsula colonies. Lactation lengths were consistently longer at Ohau Point than is typically reported for the species (323-355 days vs. 285 days). Maternal investment strategies were indicative of a close, reliable food source, and showed flexibility between years through extension of foraging trip durations and the increased use of overnight foraging trips. Individual strategies did not significantly influence pup growth. However, increased maternal condition and the ability to respond to inter-annual changes in resource availability resulted in accelerated pup growth even during an El Niño event. The incidence of pups with intestinal parasites was low at Ohau Point, and the average mass of treated and non-treated pups did not differ. Pup mortality in the region was low (3% to 50 days old), however, mortality of older pups was greatly influenced by the proximity of humans, with 2/3 of pup mortality observed between the age of 50 days and weaning being caused by car collisions. The results suggest that population dynamics and maternal investment in the region are greatly influenced by local variables, notably the presence of an accessible food source within close proximity to the colony. Various indicators of health reflect a growing colony in good condition, and the presence of a reliable food source may influence the maximum density and carrying capacity the colony is able to sustain. However, some concerns are raised about the influence of human interactions in the region, and how this may affect mortality and colony dynamics in the future. Extra fencing along the Ohau Point colony is recommended to provide added protection from the road. Continued monitoring of mortality and health indices in the region is also recommended for comparison with other colonies as Ohau Point reaches carrying capacity and density-dependent pressures increase.

Polygyny is the most common mating system in mammalian species (95%), yet our understanding of polygynous systems and microevolutionary processes is still limited. Pinniped mating systems range from extreme polygyny (e.g. elephant seals) to sequential female defence by males and hence have often been used as models for mating system studies. Parentage analysis has enabled the examination of mating success, the identification of pedigrees, and the elucidation of social organisation, greatly enhancing our understanding of mating systems (Chapter 1). However, such analyses are not without pitfalls, with erroneous assignments common in open systems (i.e. when parental and offspring samplings are incomplete). We investigated the effects of the user-defined parameters on the accuracy of parental assignment using two commonly used parental allocation programme, CERVUS and PASOS (Chapter 2). We showed that inaccurate user-defined parameters in CERVUS and PASOS can lead to highly biased output e.g. the assignment rate at 95% CL of offspring with a sampled known mother to sampled males decreased from 58% to 32% when the proportion of candidate males sampled in the parameter options decreasing 4-fold. We found that the use of both CERVUS and PASOS for parentage assignment can increase the likelihood of correctly allocating offspring to sampled parents to 97% in our study system. Incorrect parental assignment can bias estimates of various biological parameters, such as lifetime reproductive success and mate choice preference, and hence bias ecological and evolutionary interpretations. Here, we propose solutions to increase the power of parentage assignment and hence decrease the bias in biological parameter estimates. In addition, we analysed the effects of the intrinsic bias in likelihood assignment approaches towards assigning higher probability of parentage on individuals with rare alleles and those with heightened offspring-parent matches, which increase with the number of homozygous loci (Chapter 3). We showed that, as a consequence of the algorithms employed in the programmes CERVUS and PASOS, heterozygote males with rare genotypes are assigned higher rates of parentage than males with common alleles. Consequently, where two males could both be biological fathers of a given offspring, parentage assignment will more often go to the male with the rarer alleles (most often in heterozygous loci). Thus, the commonly used parentage assignment methods may systematically bias the results of parentage analyses towards supporting the notion that females prefer more genetically unusual, most often heterozygous, males. Such a bias may sway investigators towards incorrectly supporting the concept that females choose genetically more unusual males for heterozygosity fitness benefits that underpin the good genes hypothesis, when in fact no such relationship may exist. In polygynous mammals, successful males mate with multiple females by competing with and limiting the access of other males to females. When the status of many males (age, size, health, genetic etc.) prevents them from achieving the primary mating tactic, theory predicts selection for a diversification of male mating tactics. Recent studies in pinnipeds have shown that observed male mating success was correlated to male paternity success in some species (elephant-seals), but not in others (grey seals). The existence of alternative mating strategies can explain those discrepancies. Chapter 4 implemented the guidelines provided in Chapter 2 and 3 and focused on the polygynous New Zealand fur seal Arctocephalus forsteri, predicting that 1) competition for females is likely to cause a diversification of male mating tactics; and 2) that alternative tactics can yield reproductive success. Our results indicated three male behavioural profiles; one corresponded to large territorial males and two illustrated a continuum of alternative tactics employed by non-territorial subordinate males. Our study highlights that holding a territory is not a necessary condition for reproductive success in a population of otariids. The degree of sexual size dimorphism in polygynous species is expected to increase with the degree of intra-sexual competition and in turn with the degree of polygyny. The life history of an individual is the pattern of resource allocations to growth, maintenance, and reproduction throughout its lifetime. Both females and males incur viability costs of mating and reproduction. However, male viability costs due to increase growth and male-male competition can be greater than female viability costs of mate choice and reproduction. Although an abundant literature on sexual dimorphism in morphology, physiology, and parasite infections is available, little is known on the intra-sexual differences in physiology and parasite infections associated to the reproductive success of different mating strategies in mammalian species. Chapter 5 examined the reproductive costs between territorial and subordinate males New Zealand fur seal related to their relative reproductive success using a multidisciplinary approach (behaviour, genetics, endocrinology, parasitology). We found that dominant New Zealand fur seal males endure higher reproductive costs due to the direct and indirect effects of high testosterone levels and parasite burdens. Our study highlights that holding a territory confers a higher reproductive success, but induces higher costs of reproduction that may impair survival. Understanding microevolutionary processes associated to polygynous systems is fundamental in light of the ongoing anthropogenic alteration of the environment through climatic variations and habitat reduction which ultimately affect opportunity for sexual selection and shape the life history trade-offs.
