Abstract (sommario):
Municipal commonage in South Africa offers previously disadvantaged, landless residents access to both direct ecosystem goods and services (EGS) that provide additional income options and indirect social and cultural services. Given that EGS production is a function of ecosystem health, it is imperative that commonage land be managed to maximize current local benefit streams while ensuring future options through the maintenance of natural ecosystem functions. The payments for ecosystem services (PES) model potentially offers an opportunity for contributing to local economic development while providing fiscal incentives for environmentally sustainable natural resource management. PES depends on the demonstration of quantifiable changes in EGS delivery due to improvement in or maintenance of high ecosystem health that are a verifiable result of modifications in management behavior. This thesis therefore compared spatial variations in (i) ecosystem health and (ii) nine direct and indirect EGS values derived from natural resources on the Bathurst municipal commonage and neighboring Waters Meeting Nature Reserve (NR) to explore how different land use intensities affect ecosystem health and the resulting provision of EGS. The results indicate that the total economic value of annually produced EGS on the study site is nearly R 9.8 million (US$ 1.2 million), with a standing stock of natural capital worth some R 28 million (US$ 3.4 million). Nearly 45% of the total annual production is attributed to Waters Meeting NR, with roughly 34% from the low use zone of the commonage and the remaining 22% from the high use zone. Of the total annual production value on the study site, roughly 59% is derived from indirect (non-consumptive) uses of wildlife for the study site as a whole, though this proportion varies from 25% in the high use zone of the commonage to 94% on Waters Meeting NR. The two largest annual production values on the study site derive from ecotourism (R 3.5 million, US$ 0.4 million) and livestock production (R 2.6 million, US$ 0.3 million), suggesting that while increased production of indirect EGS could generate significant additional revenues, especially on Waters Meeting NR and in the low use zone of the commonage, direct (consumptive) EGS will likely remain an important component of land use on the commonage. A PES project to support the adoption of silvo-pastoral practices could provide positive incentives for improved land use practices on the commonage and potentially be financed by conservation-friendly residents of the Kowie River catchment and/or increased ecotourism revenues from Waters Meeting NR. Allowing carefully designed and monitored local access to natural resources within Waters Meeting NR could also reduce pressure on commonage resources. Together, these approaches could lead to a more sustainable subtropical thicket landscape and ensure that critical natural resources remain available to support local livelihoods in the long-term.

Abstract (sommario):
The study on different extension approaches was undertaken in the Bathurst area of New South Wales, Australia. One hundred farmers were surveyed in random pairs according to those who belong to the formal group, ???Landcare???, and those who did not. The survey included questions on personal, physical resources, ecological and economic factors, farm practices and management (including actual practice, use of extension methods and information sources) Focussing on behavioural change over time, attitudes, perceptions and intentions. The impact of extension approach on different levels of innovation was considered: simple (e.g. tree planting), medium (e.g. pasture development) and complex (soil erosion control) on behavioural change. It was hypothesised that the ???group??? extension approach should be more effective with complex innovations, but the main significant differences found were in level of tree planting (higher in government funded Landcare), money spent on erosion control (including tree planting) and attitudes to the severity of local erosion (all higher in Landcare members). There were no other differences in attitudes, intentions or change in farming practice except that non-Landcare farmers planted more pasture and applied more lime. The outcomes did not support the hypothesis, and it was not possible to distinguish the differences that did occur in performance from extension approach versus access to funds. Field days are an important extension method for the adoption of cropping by landholders. Among the different extension methods, those who conducted erosion control through pastures, preferred government officers and meetings. Those who adopted tree planting and were in Landcare preferred magazines as the extension method. This added further weight to the argument that the formal group extension approach may not be perceived by its members to have any influence on adoption at this level. Generally, mass media was more important in the early stages of adoption and personal influence more important in the evaluation stage. This also applied to simple versus complex innovations. Surprisingly all farmers placed a very high reliance on government officers for information and decision-making, particularly those in Landcare, compared to neighbours or family. Formal group extension still needs assessing but using models other than Landcare.

Abstract (sommario):
A comprehensive analysis is carried out concerning the procedures and the problems applicable to fine-particle liberation studies employing two-dimensional image analysis, especially those employing backscattered electron imagery (BEI). It is found that BEI imagery, while presenting the most cost-effective method for automated liberation studies, is prone to errors on the data collection level. Specifications are provided for sample preparation and equipment setup, allowing errors to be minimized. A processing algorithm is developed for cleaning BEI images prior to data compilation, and statistical tests for data integrity are evaluated. It is found that the recalculated sample grade, the most commonly used test of data integrity, is inadequate and misleading. Some alternative methods of data evaluation are presented. The statistical basis of data reduction and data interpretation is reviewed. The effects of stereological bias upon two dimensional liberation data are assessed using a simple geometrical model, whereupon it is found that relatively simple translations may be made between uncorrected and corrected data. A case study of fine particle liberation and circuit assessment is presented using samples from the copper/lead separation circuit of Brunswick Mining and Smelting, Bathurst, N.B.

University of Western Australia. School of Earth and Geographical Sciences, 2003. http://theses.library.uwa.edu.au/adt-WU2003.0025.

Abstract (sommario):
[Truncated abstract] The Northern Bonaparte Basin and adjacent Darwin Shelf form part of a major petroleum province on the northwestern margin of Australia. The middle to Late Cretaceous Bathurst Island Group consists of siliciclastic and pelagic carbonate strata that form the regional seal to underlying Upper Jurassic and Lower Cretaceous reservoir sandstones. The Bathurst Island Group has previously been subdivided into four stratigraphic sequences or ‘play intervals’ bound by regional disconformities in the Valanginian (KV horizon), Lower Aptian (KA horizon), upper Lower Cenomanian (KC horizon), Middle Campanian (KSC horizon), and at the CretaceousPaleocene boundary (T horizon). Correlation of these sedimentary packages and stratigraphic surfaces requires high-resolution calcareous microfossil biostratigraphy, while palaeobathymetric determinations based on benthonic foraminiferal assemblages are important for determining the subsidence history of the area and relative sea-level changes. This study presents the first detailed stratigraphic distributions, taxonomic lists and illustrations of foraminifera and calcareous nannofossils from the Bathurst Island Group of the Northern Bonaparte Basin and Darwin Shelf. A biostratigraphic framework has been constructed for the study area incorporating ‘standard’ (Tethyan) Cretaceous planktonic foraminiferal and calcareous nannofossil events where applicable, and integrating locally defined events where necessary. This framework allows Cretaceous strata to be correlated regionally across the study area and to the global chronostratigraphic scale. Correlation of the Northern Bonaparte Basin and Darwin Shelf strata to the Cretaceous Stages and international time scale is based on recent ties of nannofossil and foraminiferal events to macrofossil zones and palaeomagnetic polarity chrons at ratified and proposed Global Stratotype Sections and Points (GSSPs). Calcareous nannofossil events recorded in the study area that are critical for defining stage boundaries include the lowest occurrences of Prediscosphaera columnata, Micula decussata, Lithastrinus grillii, and Aspidolithus parcus parcus, and the highest occurrences of Helenea chiastia, Lithastrinus moratus, Aspidolithus parcus constrictus, and Eiffellithus eximius. Important planktonic foraminiferal events for correlation include the lowest occurrences of Rotalipora gr. globotruncanoides, and Dicarinella asymetrica, and the highest occurrences of Planomalina buxtorfi, Rotalipora cushmani, and Dicarinella asymetrica. During the middle to Late Cretaceous the Northern Bonaparte Basin and Darwin Shelf occupied mid-high palaeolatitudes between 35ºS to 45ºS. These palaeolatitudes are reflected in the transitional character of the planktonic microfossil assemblages, which combine elements of the low-latitude, warm-water Tethyan Province to the north and the cool-water high-latitude Austral Province to the south. ‘Standard’ Tethyan zonations are most applicable for uppermost AlbianMiddle Campanian strata because equator-to-pole temperature gradients were weakly developed, and global climate was warm and equable during this interval. These conditions resulted in broad latitudinal distributions for Tethyan marker species, and consequently most UC calcareous nannofossil zones and European-Mediterranean planktonic foraminiferal zones are recognised. In contrast, the EarlyLate Albian and the late Middle CampanianMaastrichtian were intervals of greater bioprovinciality and stronger palaeotemperature gradients. In these intervals application of the Tethyan zonations is more difficult, and a number of the Tethyan biostratigraphic markers are absent from the study area (e.g. Ticinella species in the Albian and Radotruncana calcarata in the Late Campanian). Cretaceous palaeobathymetric reconstruction of the study area is based on comparison of the foraminiferal assemblages with those of previous Cretaceous palaeobathymetric studies. Marginal marine assemblages consist solely of low diversity siliceous agglutinated foraminifera (e.g. Trochammina). Inner and middle neritic water depths (0-100 m) contain rare to common planktonic foraminifera (mainly globigerine forms), robertinids (e.g. Epistomina), siliceous agglutinates, lagenids, buliminids (e.g. Neobulimina), and rotaliids. The outer neritic zone (100-200 m water depth) contains abundant planktonic foraminifera (keeled and globigerine), calcareous agglutinates (e.g. Dorothia), and diverse lagenids, buliminids, and rotaliids. Upper-middle bathyal water depths (200-1000 m) are characterised by abundant planktonic foraminifera, common siliceous agglutinated taxa (e.g. Glomospira), rare to common Osangularia, and globular species of Gyroidinoides, Pullenia, and Paralabamina.

Abstract (sommario):
3-D geographic information systems (GIS) provides a powerful tool for visualizing and interpreting the subsurface distribution of geology and hydrothermal parameters that are important in exploring for deposits concealed at depth. For the purpose of this study, restoration of a historical mine data set was undertaken with the goal of migrating information from paper records to fully linked data sets suitable for interpretation in 3-D GIS. Heath Steele, in the Bathurst Mining Camp, northern New Brunswick, is one such deposit with historical records that include the distribution of ore-associated iron formation, massive sulfides and host rocks. Structural and stratigraphic interpretations from previous studies and exploration programs were incorporated in the model, along with fabric measurements, regional geology, drillcore logs and geophysical data. This study shows how revisiting historical mine data in a 3-D environment can generate new knowledge about an ore deposit and particularly the spatial context of hydrothermal features in a complexly deformed setting that may aid future exploration.

Abstract (sommario):
En 1925, les Soeurs de la Charité de Québec s'installent à Port-Merrier, sur l'île d'Anticosti, et fondent un couvent et un pensionnat, afin de dispenser un enseignement primaire aux enfants. Anticosti est alors aux mains d'un riche propriétaire français, qui la vendra l'année suivante à une compagnie forestière. De 1926 à 1973, les religieuses poursuivent leur oeuvre, alors que l'île d'Anticosti se destine à l'exploitation forestière. Au gré des événements, leur périple sur cette île les mettra souvent à rude épreuve. Elles seront confrontées à un milieu très différent du leur et devront constamment négocier avec les administrateurs de la compagnie forestière pour assurer la pérennité de leur institution. Ce mémoire de maîtrise porte donc sur l'oeuvre d'une communauté religieuse dans un milieu insulaire dominé par une compagnie forestière. L'étude vise à comprendre les motivations qui ont poussé, d'une part, les Soeurs de la Charité de Québec, d'autre part, les propriétaires successifs de l'île, à vouloir instaurer et maintenir un couvent sur l'île d'Anticosti. Elle se veut également un reflet des relations entres ces différents acteurs, notamment en ce qui concerne la gestion et le fonctionnement du couvent. De manière plus générale, ce mémoire révèle une situation particulière, celle d'une communauté religieuse établie dans un"village de bois", et lève le voile sur les relations employées/employeurs qui se tissent entre les protagonistes.

Testo completo
Abstract (sommario):
An investigation of the anatomy and gas exchange characteristics of Mariscus congestus in three different habitats was undertaken in order to establish whether M. congestus from the three different habitats displayed any ecotypic responses when placed in a new similar environment. It was hoped that the results of this investigation would yield evidence that would support the ecotype concept similar to the investigations of Milner and Hiesey (1964), Green (1969) and Slayter and Ferrar (1977). On the basis of the site leaf anatomy, M. congestus investigated at the coast (site 1) differed in many respects from the inland plants (sites 2 and 3). These differences suggest that the coastal plants may have undergone a slight ecotypic divergence from the inland plants. The anatomical investigation also suggested that the leaves of M. congestus from all three sites may either be C₄ NADP-ME or PCK and that all had typical Chlorocyperiod anatomy. The habitat microclimates at sites 1-3 had different light and water regimes. There were no significant differences between the 12 month temperature environments of the three sites. There was however, a minor difference between the coastal (high temperature) and the inland (lower temperature) sites. M. congestus at the three sites had significantly different CO₂ assimilation rates, transpiration and stomatal conductance in response to the differing habitat microclimates. The water use efficiency of the sites were however, similar. Site 1 attained the highest CO₂ assimilation rates, transpiration, stomatal conductance, and water use efficiency and site 3 the lowest. Under similar conditions the gas exchange data for the potted plants indicated that M. congestus from the different sites was typically C₄. The optimal photosynthetic temperatures of all the sites was above 30°C and they did not show significant inhibition of CO₂ assimilation by different oxygen concentrations. The results of the laboratory investigation of the potted plants suggested that the only site-specific (ecotypic) response of M. eongestus was the light intensity at which the plants from the different sites were light saturated. The light and temperature response of field plants under field conditions was not comparable to the light and temperature response of potted plants under laboratory conditions. This may have been due to the field results being obtained under differing water and soil nutrient regimes. The potted plants may also have had a reduced root mass compared to their field counterparts and the potted plants may have also have become root bound. Under field conditions the plants had differing light saturation points and optimal photosynthetic temperatures compared to the potted plants. This investigation thus did not support the hypothesis stated in this thesis. The data in this investigation thus may indicate that plants with as diverse habitats as Mariscus congestus that are removed from their natural habitats display rapid changes in gas exchange characteristics in response to their new microclimates, with few ecotypic physiological characteristics of the old habitat being retained.

Abstract (sommario):
This study is a descriptive analysis of the occurrence of the sociolinguistic variables of pronunciation associated with all forms of ‘there’ and Non-Standard There-tag (NST-tag) in Bathurst English. Participants were interviewed and the occurrences of ‘there’ were obtained through the use of sociolinguistic interviews with 15 speakers. The incidences of ‘there’ were sorted based on grammatical category and pronunciation and were subsequently analyzed based on age and gender. The results indicate that older speakers use non-standard pronunciations of ‘there’ more than younger speakers and they also use NST-tag more than younger speakers. Younger speakers mostly use standard pronunciations of ‘there’ and use NST-tag very little. This may indicate age and gender grading or a change in progress in that vernacular is giving way to more standard speech in this community.

Abstract (sommario):
I studied the autecology, community ecology, and genetics of an endangered butterfly, the maritime ringlet (Coenonympha nipisiquit McDunnough), that inhabits a limited number of salt marshes in northern New Brunswick and in the Gaspé Peninsula of Québec. I studied the survival rate of first- and second-instar larvae in various microhabitats in a salt marsh at Daly Point Natural Reserve, Bathurst, New Brunswick. I found they survived significantly better in microhabitats dominated by Spartina patens (Aiton) Muhl. at an intermediate elevation. I investigated the tolerance of the maritime ringlet larvae to tidal submergence and compared their performance to a closely related taxon, the inornate ringlet (C. tullia inornata Edwards). The experiments revealed that the maritime ringlet possesses unique adaptations to tidal submergence. I examined the flight and oviposition behaviors of adult females in response to microhabitat. I found that they did not discriminate between microhabitats based upon the likelihood of larval survival as long as S. patens or other potential hosts were abundant. I explored the correlation between predator species richness and abundance with the larval survival rate in microhabitats. I found that predator abundance and species richness often responded negatively to increasing tidal flooding, suggesting that high larval mortality at high elevation sites can be caused by high predation pressure. Lastly, I investigated the possibility of genetic introgression between the maritime ringlet and inornate ringlet and reconstructed the phylogeny of the C. tullia-group taxa in North America. The genetic evidence did not support the possibility of large-scale genetic introgression and raised the taxonomic status of the maritime ringlet from a subspecies of holarctic C. tullia to a full species. The phylogenetic analyses suggested that the divergence of the maritime ringlet was much earlier than previously believed. My results will aid in protection and recovery of this endangered species.

Abstract (sommario):
Les propriétés hydrauliques d'un massif rocheux fracturé affectant la migration de polluant ont été analysées dans le cadre d'un plan de fermeture d'une mine. La mine à ciel ouvert no 6 de la Brunswick Mining and Smelting Corp. a été en production de 1965 à 1983. L'excavation est présentement à se remplir par les eaux souterraines et le drainage de surface. Après le remplissage de la mine, l'eau acide pourra s'écouler vers le sud à travers le massif rocheux. La présente étude a pour objectif principal la caractérisation de l'écoulement à l'intérieur du massif rocheux entre la mine et le ruisseau Austin situé à environ 700m en aval (au sud) de la mine. Trois forages d'une longueur totale de 292m ont été exécutés pour cette étude. L'orientation des carottes de forage a été mesurée à l'aide d'un orienteur de type "plomb-plasticine". L'orientation vraie des fractures a été déterminée. Un enregistrement vidéo de l'intérieur des trous de forage a permis d'identifier les fractures naturelles de la roche. Des relevés de fractures ont été réalisés sur deux zones d'affleurement situées entre la mine et le ruisseau: les secteurs nord et sud. Les différentes données sur la fracturation ont permises de faire ressortir des variations spatiales dans la distribution des orientations de fracture. La densité de fracturation varie avec la profondeur mais est similaire pour les secteurs nord et sud. Deux types d'essais hydrauliques ont été effectués, soit des essais d'injection à charge constante et des essais de choc hydraulique ("slug tests"). La qualité et la fiabilité des données ont été analysées à l'aide de deux types de graphiques. La conductivité hydraulique des intervalles estimées directement varie entre 1,0 x 10-8 et 1,2 x 10-5 m/s. La conductivité hydraulique radiale de la matrice rocheuse estimée en laboratoire varie de 10-12 pour les échantillons fissurés, à 10-13, 10-14 m/s pour les échantillons sans fissure. Une analyse comparative des résultats des différents types d'essai a permis d'évaluer la fiabilité des données et d'assigner des limites aux valeurs qui n'ont pu être estimées directement. Les essais hydrauliques en forage ne permettent pas de définir une corrélation nette entre la présence de fractures et la valeur de la conductivité hydraulique. Les résultats des essais hydrauliques in situ ne montrent pas de variation significative de la conductivité hydraulique ni avec la profondeur, ni horizontalement. Les valeurs de débits estimés soulignent qu'une très faible portion du massif rocheux (environ 10%) peut contrôler la majorité (environ 90%) des apports d'eau au ruisseau Austin. La vitesse de filtration est estimée avec un gradient de 0,04 pour deux valeurs extrêmes de porosité, soit: la porosité de fracture minimale de 0,0027%, et une porosité effective maximale de 1%. La grande variabilité des résultats obtenus reflète l'incertitude sur plusieurs paramètres hydrauliques, principalement la porosité. Ces estimations pourraient être raffinées avec certains travaux complémentaires.

The overarching question under investigation in this thesis is the extent to which the ideals of penal management as espoused by both British and Colonial authorities were implemented in the day to day administration and management of a convict work force. The focus of the examination is the construction of Major Thomas Mitchell’s line of road between Mt. Victoria and Bathurst in the 1830’s. Specifically the thesis documents the various sites on the line of road with a particular emphasis on the administrative centre and principal facility, No. 2 Stockade Cox’s River, to explain the dynamic interaction of the network and its role in the penal repertoire of New South Wales. In bringing together a large range of sources the thesis has enabled the first thorough reading of the convict sites associated with the Western road. This has led to a multi-dimensional understanding of the place, its people, and the process of its construction. It provides a basis for future scholarship on this neglected network, located almost at the doorstep of greater Sydney, on the western fringe of the Blue Mountains.
