The question of the origins of a Metis identity in Canada is one that has been contemplated by several scholars. These scholars have taken various approaches to the question, many focusing solely on the social and political aspects of Metis history. While such approaches can be useful, they ignore the crucial influence of the economic and labour relations of the Rupertsland fur trade in the development and expression of a distinct Metis identity in western Canada. The unique economic and labour relations of the Rupertsland fur trade, identified by H. Clare Pentland as personal labour relationships, allowed a cohesiveness and inter-connectedness to develop between the Aboriginal labourers and their European employers which emphasized the interdependencies inherent in the industry. However, while personal labour relations were an important catalyst for the development and expression of a distinct Metis identity, it is too simplistic to suggest that it was these relations alone that encouraged such a phenomenon. The northern Australian cattle industry utilized similar economic and labour relations and yet a distinct mixed descent identity did not develop in Australia. Therefore, the external influences in the industry must also be examined. The four most important external influences that encouraged the development of a Metis identity in Canada and discouraged a similar event in Australia were: the needs of the colonial employers in regards to land tenure; the economic opportunities available to the people of mixed descent; the educational opportunities available to the people of mixed descent; and, the time depth of contact in both industries. These four external influences combined with the use of personal labour organization in the Rupertsland fur trade encouraged the development and expression of a distinct Metis identity in Canada.

Doctor of Philosophy(PhD) / Communication is a fundamental process that allows animals to effectively transfer information between groups or individuals. Recognition plays an essential role in permitting animals to distinguish individuals based upon both communicatory and non-communicatory signals allowing animals to direct suitable behaviours towards them. Several modes of recognition exist and in colonial breeding animals which congregate in large numbers, acoustic signalling is thought to be the most effective as it suffers less from environmental degradation. Otariid seals (fur seals and sea lions) are generally colonial breeding species which congregate at high densities on offshore islands. In contrast to the other Arctocephaline species, the Australian fur seal, Arctocephalus pusillus doriferus, along with its conspecific, the Cape fur seal, A. p. pusillus, display many of the behavioural traits of sea lions. This may have important consequences in terms of its social structure and evolution. The acoustic communication of Australian fur seals was studied on Kanowna Island, Bass Strait, Australia. Analysing the acoustic structure of vocalisations and their use facilitates our understanding of the social function of calls in animal communication. The vocal repertoires of males, females, pups and yearlings were characterised and their behavioural context examined. Call structural variations in males were evident with changes in behavioural context, indicating parallel changes in the emotive state of sender. For a call to be used in vocal recognition it must display stereotypy within callers and variation between them. In Australian fur seal females and pups, individuals were found to have unique calls. Mutual mother-pup recognition has been suggested for otariids and this study supports the potential for this process to occur through the use of vocalisations. Call structural changes in pup vocalisations were also investigated over the progression of the year, from birth to weaning. Vocalisations produced by pups increased in duration, lowered in both the number of parts per call and the harmonic band containing the maximum frequency as they became older, suggesting calls are changing constantly as pups grow toward maturity. It has been suggested through descriptive reports, that the bark call produced by males is important to vocal recognition. The present study quantified this through the analysis of vocalisations produced by male Australian fur seals. Results support descriptive evidence suggesting that male barks can be used to discriminate callers. Traditional playback studies further confirmed that territorial male Australian fur seals respond significantly more to the calls of strangers than to those of neighbours, supporting male vocal recognition. This study modified call features of the bark to determine the importance to vocal recognition. The results indicate that the whole frequency spectrum was important to recognition. There was also an increase in response from males when they heard more bark units, indicating the importance of repetition by a caller. Recognition occurred when males heard between 25-75% of each bark unit, indicating that the whole duration of each bark unit is not necessary for recognition to occur. This may have particular advantages for communication in acoustically complex breeding environments, where parts of calls may be degraded by the environment. The present study examined the life history characteristics of otariids to determine the factors likely to influence and shape its vocal behaviour. Preliminary results indicate that female density, body size and the breeding environment all influence the vocal behaviour of otariids, while duration of lactation and the degree of polygyny do not appear to be influential. Understanding these interactions may help elucidate how vocal recognition and communication have evolved in different pinniped species.

This thesis builds a demographic profile of the Northern Fur Seal (NFS) population being consumed at DfSi-4 and DfSj-23 to determine if a NFS rookery existed within close proximity to both sites. A demographic profile of the death assemblages found at each site was built using visual identification, a non-linear growth curve algorithm developed by Michael Etnier (2002) and ancient DNA analysis. This study uses the demographic profile to evaluate the existence of a NFS rookery within the Barkley Sound area. Ultimately the existence of a rookery depends on demonstrating the existence of four age categories: fetal/newborn, juvenile, adult and adult male. Results indicate that a rookery likely existed near DfSj-24A, but there is much less certainty for DfSi-4. Further inquiry is now possible into the economic and ecological relationships that existed between the Toquaht and the NFS within the Barkley Sound area. / February 2016
