Written in memory of the first women convicts transported to Botany Bay, this unthinkable history, a concept posed by the historian, Paul Carter, is an experiment in extending the boundaries of academic remembering, so that the complex lives of those resilient women might be given recognition. Researching the women??s lives required an ethnographic method, or ??spatialized?? history, based on original archival research, together with research of rituals, art, literature, newspapers and music; and, importantly, the laws which circumscribed their behaviour. A research focus was thus the administration of criminal codes and the character of prominent judges, including the significance of the Recorder of London. Theories of history based on the work of philosophers such as Heidegger, Deleuze, Guattari, Derrida, Foucault and the ethical philosopher, Wyschogrod, with her feminist perspective, have influenced narrative themes and tropes. This experimental hybridization of historical methods and the poetics of fiction might be classified as ficto-critical historiography, where ficto-critical functions as an epithet, not a polarity, as is the case with ficto-historiography and the coinage, faction. As a meditation on the ??maybe?? of historiography, the experiment enters the debates about the relationship between history and fiction and the significance of remembering. The incompleteness of records, their silences and partialities, the forensic reading required to contextualize them, the perspective from which the narrative is told, together with the metaphorical levels of all writing, are explicitly acknowledged. Fundamental to that acknowledgement is the narrative trope of simulacra. The narrative figures are thus copies without originals; they are an acknowledgement of the absence which haunts memories, while avoiding scepticism or relativity. The semi-omniscient, intrusive voice of the narrator, the dialogic placement of other ??voices??, variously contrary, affirmative, informative or philosophical; together with the acknowledged artifice of narrative dramatizations in which the figures are assembled from multiple sources, are important elements in the grammar of this transgressive act of remembering with its footnotes and phantoms.

The New Zealand aquaculture industry during the late 1990s and early 2000s experienced a significant and sustained period of growth. Greenshell mussels (Perna canaliculus) are proving to be a popular and valuable cultured species, with large domestic and international markets. Traditionally, these bivalves have been farmed within enclosed embayments and on relatively small scales (~3 Ha). The recent expansion of the industry coupled with the near saturation of existing 'traditional' sites and new culture technologies has led the industry toward alternate environments, notably exposed offshore sites. Initial proposals within the Bay of Plenty have included multiple farms of ~4500 Ha each. This novel approach to shellfish culture created uncertainty with respect to potential environmental impacts, cumulative effects, and sustainable carrying capacities within these exposed open-coast locations. In zoning for Aquaculture Management Areas (AMAs), environmental managers must be informed of each of these aspects to ensure the rational and sustainable use of the coastal-marine space. The overall goal of this study is to determine the potential for environmentally sustainable large-scale offshore mussel culture within the Bay of Plenty marine environment. The long term sustainability of aquaculture development on an open coast is a function of many influences which can vary in both time and space. The benthic environments of the Bay of Plenty exhibit great variability in their ability to assimilate waste inputs from suspended mussel culture; a direct function of the variability in sedimentary environments and benthic habitats within the region. Specifically, silty sediments with low natural organic contents, generally found between 40 and 100 m depths are the most suitable locations for sustainable mussel aquaculture from an environmental impact perspective. Both observations and model predictions indicate productivity potential within the region to be greatest within neritic zones of the western Bay of Plenty. Local wind forcing is the predominant mechanism forcing local shelf currents. Current meter data and numerical modelling tests from this study indicate that local winds explain the majority of water current variability on the shelf, generate the delivery of new nutrients to the shelf through upwelling, and hence create the variability in productivity potential. Complicating the AMA zoning process for environmental managers, however, are existing uses of, and societal values toward, the coastal-marine environment. GIS planning tools have been shown to be effective at minimising conflicts and maximising sustainability potential through informed site selection. Within the Bay of Plenty, these preferential sites are located on the mid-shelf (60-80 m depths) offshore from Pukehina, Matata, and Whakatane. This study shows that the simulated cumulative lower trophic-level depletion impacts of two large (~5000 Ha) proposed offshore mussel farms vary seasonally as a result of subtle changes in ecosystem dynamics and mussel feeding patterns. At proposed stocking densities, largest relative impacts are expected during autumn and winter, when relative phytoplankton biomass is low and growth rates slow. During spring, while absolute impacts are greater than those during autumn/winter, greater phytoplankton-zooplankton biomass and faster growth rates result in quicker recovery times and reduced 'depletion halo' extents. Year-long predicted impacts are below those applied as 'acceptable limits of change', both within New Zealand and internationally, indicative of the ecological carrying capacity.

Abel Tasman, a Dutchman, was the first person to put New Zealand on European maps over three hundred years ago (in 1642) and today there are over twenty-eight thousand people living in New Zealand who identify themselves as Dutch and twenty-seven thousand people speaking the Dutch language. Previous research has explored various aspects of Dutch migration, including migrant experiences, culture and language yet only de Bres (2004) compares the experiences of Dutch immigrants across time periods of their arrival. Cultural retention and maintenance has mainly been assessed via the use of the Dutch language rather than through other methods, such as Dutch customs and social networks. The main reason for this research is to compare the experiences and cultural identity of the three 'waves' of Dutch migrants, which has not been undertaken before. This study interviewed six Dutch settler families living in the Bay of Plenty, from three time-periods (1950s; 1960s to 1980s; and 1990s to today) and across generations in order to compare their experiences and assess if and how they maintain their Dutch identity through their use of customs and social networks. Open-ended questionnaires and interview schedules were used to interview the sixteen participants. Content analysis was undertaken for the majority of the questionnaire and interview schedules. For the remaining questions that focused on social networks, the structural aspects of the social support for participants were measured in terms of the social network characteristics, size, density and multiplexity. The study found an overall retention of Dutch identity across all time-periods for generation one (generation one refers to the migrating parents) with all families using the Dutch language within their own homes, yet only one family maintaining their Dutch identity through social networks and only one family maintaining their Dutch identity through the use of customs. The second and third generation participants have little to no interest or involvement in the Dutch culture or community. One second generation participant considered herself Dutch-Kiwi, with the remaining second generation participants considering themselves New Zealanders. Only one person from the third generation participated and she identified herself as a Dutch-Kiwi. Overall, this study supports the perception of the 'invisible Dutch' however due to the small sample size it is impossible to make conclusive statements concerning the Bay of Plenty Dutch community. There is a limited amount of research comparing the experiences of Dutch migrants and how their cultural identity is maintained through their social networks; therefore further research is required to fill this gap.

This thesis is concerned with the ways Imperialism (and consequently colonialism) has pervaded the indigenous �primitive� world. Protectorates and �the colonies� reflected imperialist ideals, expansion, territory, external revenue and power. Missionaries were the footmen of colonial policy. The relations forged between these evangelists and the indigene have been thoroughly studied and scrutinised. However, reported interaction has been about missionaries and the �native�, with less about that between the indigenes, individual and tribe, elder and young. The thesis intends to redress this imbalance in the Bay of Islands from 1814 to 1834. The following work is an examination of a process of social change in Aotearoa. In the early 19th century the physical, spiritual and intellectual contact made between Maori peoples and the European explorers, scientists, and missionaries involved a deliberate cultural entanglement. It is the processes of acculturation, assimilation, or simply misunderstanding that are of interest. The study will have several foci involving the reaction of peoples of the Bay of Islands to the missionary institution of religious education. Chapter One addresses the theoretical location of the peoples that interacted in the Bay, while the second chapter is a brief description of a Maori coastal society prior to the arrival of literate missionaries. Chapter Three is about the cultural and social engagements of Ruatara, Marsden, Kendall and Hongi. The final chapter is a biographical exploration in the life of Rawiri Tawhanga and his interactions with missionaries and Maori of the Bay. Fundamentally it is the indigenous interaction during the initial periods of external European contact and, therefore, the effects of internal societal change that the author wishes to examine.

Studies were conducted during late winter and spring of 1970 to establish the extent of spawning of Pacific herring (Clupea harengus pallasi Valenciennes) in the Yaquina estuary, and to define the degree of egg mortality on certain substrates. Routine surveillance of the north shore of the estuary provided information on the length of the spawning season, the number of separate spawnings which occurred, the extent of spawning into brackish water, and the types of substrates utilized for spawn deposition. Random sampling of egg deposits at specific locations within the estuary, and at frequent intervals following deposition provided estimates of spawn mortality on two commonly used plant substrates, Fucus sp. and Zostera sp. These included estimates of the amount of eggs removed from the substrates prior to commencement of hatching, and estimates of the mortality among eggs which remained attached to the substrates. One series of samplings of a deposit of eggs on Fucus was designed to establish the extent of bird predation on the eggs. Results from the spawn survey indicated that at least five separate spawnings occurred during the season. Initial spawning took place on February 5 in the lower estuary (from the south jetty to a point three miles upriver from the mouth). Subsequent spawnings occurred in the third, fifth, sixth, and seventh weeks following this initial deposition, and appeared to take place exclusively in the middle and upper estuary (from three and one half miles to ten miles upriver from the mouth). Among the substrates observed with eggs Fucus appeared to be the most extensively utilized, while localized deposits were noted on Zostera, bare rocks and pilings. Spawning was predominantly located on substrates lying above mean lower low water. Analysis of the samples collected from four populations of eggs deposited on Fucus, and one population deposited on Zostera revealed that egg removal was extreme during the period of incubation. Recorded losses from initially sampled populations of eggs on Fucus ranged from 78% to 1OO% based on sample means. A 9l% loss was recorded for the one Zostera population sampled. A comparison of a protected with an unprotected segment of a sampled population on Fucus indicated that birds contributed at least 80% to the removal of eggs from the unprotected segment. The observed presence of birds on all of the sampling areas when eggs were present suggests that predators accounted for the extensive losses from these areas. Analysis of the ratios of dead eggs to the total number of eggs in samples collected from Fucus substrates provided estimates of natural mortality. Low rates of mortality (about 20%) were recorded for two populations sampled during a period in which the weather was cool and moist, while considerably higher rates (about 50%) were observed in samples from a population exposed to a dry and relatively warm climate. Dessication of eggs was therefore indicated as a significant cause of mortality of eggs remaining attached to substrates exposed to drying conditions in the atmosphere. In addition to these field studies, a study was conducted in the laboratory to define the effects, on the survival of herring eggs to hatching, of combinations of three environmental parameters: temperature, salinity, and exposure to air. Groups of artificially fertilized eggs were incubated in the 18 test environments provided by the different combinations of three temperatures, three salinities, and exposure and non-exposure to air. Survival of eggs to hatching remained high (from 60% to 86% of total eggs in each environment) except for eggs incubated in the highest temperature ( 11 °C.) and subjected to eight hour exposure periods. Average survival in these environments was 5.2% and 24.2% (for two replicates). These observations lend support to the findings from the field sampling studies that survival of herrings eggs can be tenuous when subjected to exposure to air. / Graduation date: 1972

The genetic structuring of populations can be influenced by present processes and past events. One of the largest historical events to affect the distribution and genetic characteristics of present-day North American biota is the Pleistocene glaciation. Thus, the study of post-glacial colonization patterns of species in northern landscapes can relay important ecological information, as species had to expand their range extensively following the retreat of the glaciers and are often at the terminal end of their expansion. These species consequently exhibit the genetic fingerprints of sequential founder events, in turn decreasing the genetic variation available for adaptation. Using amphibians to investigate post-glacial range expansion is advantageous, as they have limited dispersal abilities revealing fine-scale patterns and they are thought to be one of the first vertebrates to colonize post-glacial habitat. Therefore, to model the phylogeography of a primary colonizer and the population structure of anurans in northern landscapes, population genetics analyses of wood frogs (Lithobates sylvaticus) were performed in the James Bay area. Wood frogs were sampled from 17 localities around James Bay and genetic analyses were conducted with seven microsatellite loci and mitochondrial DNA sequences of the ND2/tRNATRP genes. Results show that the post-glacial recolonization of the James Bay area by wood frogs originated from the putative refugium in western Wisconsin, an area known as the Driftless Area. Two routes were taken by founders to colonize the James Bay area: one north-west of Lake Superior, colonizing western Ontario, and one through the Upper Peninsula of Michigan, colonizing southern and eastern Ontario and western Québec. Interestingly, the meeting of the two lineages south-west of James Bay led to the establishment of a zone of higher genetic variation than expected under the founder effect hypothesis. Additionally, population structure analyses revealed the segregation of three genetic populations east, north-west, and south-west of the bay, the latter showing the highest genetic variation and likely representing a zone of secondary contact. This study shows that past events such as post-glacial range expansions can explain present patterns of genetic variation and population structure, and that studies in northern landscapes may be very useful in understanding genetic patterns throughout the range of a species.
