Abstract (sommario):

Approximately 86 specimens of Bathurstia denticulata Hueber were collected from upper Bathurst Island and lower Stuart Bay beds of Bathurst Island, Canadian Arctic Archipelago. Bathurstia was a component of a zosterophyll-dominated flora of Pragian age (Lower Devonian) that existed at low paleolatitudes in northern Canada. The large collection of well-preserved materials permits reconstruction of the plant as a robust scrambler of about 30 cm in height. Stems bear short, shelf-like emergences in two rows, and branch isotomously, although sparsely. Rooting organs, representing some of the oldest known for land plants, arise from the main aerial axes, although they are also associated with small, subordinate shoots interpreted as plantlets. Numerous specimens are fertile, with sporangia borne in dense terminal spikes. Spikes include two rows of overlapping, discoid sporangia. Isospores are round and featureless, and assignable to the genus Calamospora. While Bathurstia apparently originated from among the isotomously branching bilaterally symmetrical zosterophylls, the phylogenetic relationships of Bathurstia to known taxa is unclear, although some resemblance to Serrulacaulis, Barinophytaceae, and the Gosslingiaceae can be documented. Bathurstia denticulata is now one of the best known of early land plants, and contributes significantly to our understanding of zosterophylls and their role in Early Devonian vegetation.Key words: Bathurstia, zosterophyll, Devonian, Canada, Arctic, evolution.

Abstract (sommario):

How caribou (Rangifer tarandus), including Peary caribou (R. t. pearyi), use their annual ranges varies with changes in abundance. While fidelity to some seasonal ranges is persistent, use of other areas changes. Consequently, understanding changes in seasonal distribution is useful for designing boundaries of protected areas for caribou conservation. A case in point is the proposed Qausuittuq (Northern Bathurst Island) National Park for Bathurst Island and its satellite islands in the High Arctic of Canada. Since 1961, Peary caribou have been through three periods of high and low abundance. We examined caribou distribution and composition mapped during nine systematic aerial surveys (1961–2013), unsystematic helicopter surveys (1989–98), and limited radio-collaring from 1994–97 and 2003–06. While migration patterns changed and use of southern Bathurst Island decreased during lows in abundance, use of satellite islands, especially Cameron Island for winter range, persisted during both highs and lows in abundance. The northeast coast of Bathurst Island was used to a greater extent during the rut and during summer at low abundance. We suggest that Park boundaries which include Cameron Island and the northeast coast of Bathurst Island will be more effective in contributing to the persistence of Peary caribou on the Bathurst Island Complex.

Abstract (sommario):

Abstract Four letters in the Adventurer are currently attributed to Johnson, who allegedly disguised his style so that they could be plausibly ascribed to his friend Richard Bathurst. A stylometric analysis, supported by internal evidence, finds the case for disguise implausible, and suggests that the letters are a collaboration between Johnson and Bathurst.

Testo completo

Abstract (sommario):

Variation in external and cranial morphology was studied in Conilurus penicillatus from six geographical regions. Sexual dimorphism (males being larger than females) in body weight and pes length was noted. Animals from Bathurst and Melville Is were distinct from other regions in that they had shorter ears, pes and head and body lengths, and dark ventral pelage. The two specimens from New Guinea had large bodies and pes, and short ears when compared with Australian animals, but incomplete data and small sample sizes precluded inclusion in the discriminant function analyses of external features. All animals from the Cobourg Peninsula, eastern Northern Territory and islands in the Gulf of Carpentaria were black-tailed. Up to 42% of animals from other populations had white tail tips. Analysis of cranial variables showed that there was a considerable degree of distinctiveness between populations. Skulls from New Guinea, and Bathurst and Melville Is, were particularly distinct from other populations. Upper and lower molar row and M1 were long in specimens from New Guinea and short in specimens from Bathurst and Melville Is. However, nasal length, braincase width and bulla length were long in specimens from Bathurst and Melville Is. Possible barriers to population interchange include bodies of water (e.g. separating Bathurst and Melville is from the mainland, and New Guinea from Australia) and unsuitable habitat in the east Kimberley and East Alligator-Arnhem Plateau regions. It is suggested that C. penicillatus had a wider distribution during periods of more mesic climate in northern Australia than at present and that its present distribution is a result of northward contraction since the postglacial thermal maximum. Taxonomic conclusions of the study are the retention of subspecific status for C. p. randi (New Guinea), C. p. melibius (Bathurst and Melville Is) and C. p. penicillatus (all other populations) but not C. p. hemileucurus (locality of type given as 'North Australia').

Ma, Svieda M., Dawn A. Kellett, Laurent Godin e Michael J. Jercinovic. "Localisation of the brittle Bathurst fault on pre-existing fabrics: a case for structural inheritance in the northeastern Slave craton, western Nunavut, Canada". Canadian Journal of Earth Sciences 57, n. 6 (giugno 2020): 725–46. http://dx.doi.org/10.1139/cjes-2019-0100.

Abstract (sommario):

The north–northwest-striking Bathurst fault in the northeastern Slave craton displaced the 1.9 Ga Kilohigok basin and the ca. 2.02–1.96 Ga Thelon tectonic zone, and projects beneath the 1.7 Ga Thelon basin where unconformity-associated uranium deposits are spatially associated with basement faults. Here we investigate the deformation–temperature–time history of the Bathurst fault rocks using structural and microstructural observations paired with U–(Th–)Pb and 40Ar/39Ar geochronology. Highly strained hornblende-bearing granitoid rocks, the predominant rock type on the northeastern side of the Bathurst fault in the study area, show ambiguous sense of shear suggesting flattening by coaxial deformation. Quartz and feldspar microstructures suggest ductile deformation occurred at ≥500 °C. Along the main fault trace, brittle features and hydrothermal alteration overprint the pervasive ductile flattening fabric. In situ U–Th–Pb dating of synkinematic monazite suggests ductile fabric formation at ca. 1933 ± 4 Ma and ca. 1895 ± 11 Ma, and zircon from a cross-cutting dyke constrains the brittle deformation to ≤1839 ± 14 Ma. 40Ar/39Ar dating of fabric-defining minerals yield cooling ages of ca. 1920–1900 Ma and ca. 1900–1850 Ma for hornblende and muscovite, respectively, and a maximum cooling age of ca. 1840 Ma for biotite. We suggest the ca. 1933–1895 Ma ductile flattening fabric developed during orthogonal collision and indentation of the Slave craton into the Thelon tectonic zone and Rae craton. Brittle deformation on the Bathurst fault was localised parallel to the ductile flattening fabric after ca. 1840 Ma and preceded Thelon basin deposition. Brittle deformation features in Bathurst fault rocks preserve evidence for fluid–rock interaction and enhanced basement permeability, suggesting the fault is a possible conduit structure for mineralising fluids.

Abstract (sommario):

Brachiopods are common in the lower part of the late Early to Middle Devonian Bird Fiord Formation that is a carbonate-clastic transition succession found in Arctic Canada. These brachiopods, which lived in a shallow, near-shore, marine environment, includes three new genera: Borealistrophia, Arcticastrophia, and Grinnellathyis. The strophomenid Borealistrophia, which is characterized by two pairs of straight side septa, prominent and thick socket ridges, a thick but short median septum, and a cordate ventral muscle field, is found in the Baad Fiord, Blubber Point, and Norwegian members on Bathurst, Devon, North Kent, and Ellesmere islands. The strophomenid Arcticastrophia, which is distinctive because of its stout transmuscle septa, its narrow and low medium septum, and elevated ventral muscle field, is found in the Baad Fiord Member on Bathurst and Devon islands. The athyridid Grinnellathyris, which is characterized by an imperforated cardinal plate and inverted U-shaped jugum, is found in the Baad Fiord Member on Bathurst, North Kent, and Devon islands. The similarities between Grinnellathyris and Johnsonathyris Savage, Eberlein, and Churkin, 1978, in terms of their shell size and internal structures, may indicate that the latter evolved from the former.

Abstract (sommario):

Drawing on interpretations and reactions to the violence of the 1824 Ballygiblin riot in the Bathurst District of Upper Canada, this article examines the local reception of assisted Irish Catholic immigrants to the region. In their reaction to the new arrivals, Bathurst District residents demonstrated the extent to which local priorities for settlement were at odds with that of British emigration policy. The reception of the Irish was conditioned by the legacy of the so-called “old world” in real and expected patterns of violence; by a local culture that prized loyalty, Protestantism, and pioneer manhood; and by the immediate context of British emigration policy and the process by which that policy was applied, interpreted, and experienced.

Abstract (sommario):

In the New South Wales Supreme Court decision of Anglican Development Fund Diocese of Bathurst v Palmer in December 2015, a single judge of the court held that a large amount of money which had been lent to institutions in the Anglican Diocese of Bathurst, and guaranteed by a letter of comfort issued by the then bishop of the diocese, had to be repaid by the bishop-in-council, including (should it be necessary) levying the necessary funds from the parishes. The lengthy judgment contains a number of interesting comments on the legal personality of church entities and may have long-term implications (and not merely in Australia) for unincorporated, mainstream denominations and their contractual and tortious liability to meet orders for payment of damages. The article discusses the decision and some of those implications.

Abstract (sommario):

Spatial and temporal use of seasonal, and collectively, annual ranges by four female Peary caribou (Rangifer taran-dus pearyi) was investigated using satellite telemetry. Knowledge of how caribou use space allows a better understanding of their demands on those ranges and enhances evaluation of associated environmental stressors. The study took place during an environmentally favorable caribou-year with high reproduction and calf survival and low (none detected) 1+ yr-old mortality, 1 August 1993 to 31 July 1994, Bathurst Island, south-central Queen Elizabeth Islands, Canadian High Arctic. All four females exhibited a pattern of single-island seasonal, and collectively, annual range use. Estimates of the maximum area encompassed by each individual during the course of the annual-cycle varied from 1735 to 2844 km2 (mean±SE = 2284±250 km2). Although, there was 46% spatial overlap among individual ranges, temporal isolation resulted in the four individuals maintaining seasonal ranges distinctly separate from each other. This collective area encompassed 4970 km2 and equaled about 31% and 18% of Bathurst Island and the Bathurst Island complex, respectively. Individual wintering areas formed a relatively small portion of each individual's annual range (mean±SE=71±17 km2): 24 km2, 158 days of occupation, <1% of the annual area; 70 km2, 187 days, 4%; 95 km2, 200 days, 4%; and 94 km2, 172 days, 6%. Seasonal movements were greatest during pre-rut and pre-calving.

Abstract (sommario):

Fieldwork conducted on the Cape Bathurst Peninsula, Northwest Territories, Canada, has resulted in the discovery of 75 sites representing occupations spanning more than 3,000 years. Nearly all of the sites are characterized by the predominant use of a distinctive rock called a “clinker.” Resembling a basalt-to-obsidian-like material, it is formed by the spontaneous combustion of local organic-rich shales. The fusing occurs in burning areas called bocannes that are common along the Horton River and the cliffs along the eastern shore of the peninsula. Despite the evidence for intensive use on Cape Bathurst and the more general Mackenzie Delta region, none of the four potential quarry sources yielded evidence of actual prehistoric use. This is attributed to the dynamic nature of the formation and erosion of the bocannes over the last several thousand years.

Testo completo

Abstract (sommario):

Despite 20 years of exploration between 1965 and 1992 in the northeastern part of the Bonaparte Basin, the region remains underexplored. Exploration has produced modest encouragement. The seven wells drilled in the area totalling more than 70 000 km2 include one dry gas and two gas/condensate discoveries. Explorers have targeted the Jurassic Plover Formation and Flamingo Group, but reservoir quality has often been poor in both units due largely to depth of burial.Recent regional studies of the northeastern part of the Bonaparte Basin, undertaken by the Bureau of Resource Sciences, indicate there is potential for generation and entrapment of hydrocarbons in the Cretaceous Bathurst Island Group. Geochemical results show the lower Bathurst Island Group contains good source rocks that are largely gas prone, but have the potential to charge large Cretaceous traps. Geohistory modelling suggests that the Bathurst Island Group may have entered the oil window around the Middle Cretaceous, after most of the structuring had occurred, and continued until the Middle Miocene or later. Potential reservoirs have been identified in Santonian, Campanian and Maastrichtian sands, and in fractured Albian Carbonates.Recent reports have predicted that by early next century there will be a significant increase in natural gas consumption in Australia, due to increased use for power generation and transportation, as well as further sales to the Asian market. New methanol technology could commercialise some marginal gas fields. The theme for this years APEA conference is `New Age—New Opportunities'. The Bonaparte Basin may provide the opportunity to explore for and develop new gas accumulations.

AbstractThe paper presents a geographical and historical overview of the Territory Nunavut (Canada) established in 1999 and inhabited by a majority of Inuit People. The author outlines the process that led to the conclusion of the Nunavut Land Claims Agreement and the current structure of the government of Nunavut, which can best be described as a form of Inuit self-government. Th e main objective of the paper consists in an overview and analysis of current socio-economic challenges faced by the government of Nunavut. Based on the visions of the Bathurst Mandate, the author attempts to assess the success of the ‘Nunavut Project’.The author concludes that because of Nunavut's weak economy and fi scal dependency on the central federal government of Canada, the numerous socio-economic challenges have not been resolved. The Nunavut experiment has not yet been proven a success. The prosperous vision, expressed through the Bathurst Mandate, of a viable Nunavut seems for now just an illusion.

Abstract (sommario):

In this study, we develop a method to analyse the relationships between seasonal caribou distribution and climate, to estimate how climatic conditions affect interactions between humans and caribou, and ultimately to predict patterns of distribution relative to climate change. Satellite locations for the Porcupine (Rangifer tarandus granti) and Bathurst (R. t. groenlandicus) caribou herds were analysed for eight ecologically-defined seasons. For each season, two levels of a key environmental factor influencing caribou distribution were identified, as well as the best climate data available to indicate the factor's annual state. Satellite locations were grouped according to the relevant combination of season and environmental factor. Caribou distributions were compared for opposing environmental factors; this comparison was undertaken relative to hunting access for the Porcupine Herd and relative to exposure to mining activity for the Bathurst Herd. Expected climate trends suggest an overall increase in access to Porcupine caribou for Aklavik (NWT) hunters during the winter and rut seasons, for Venetie (Alaska) hunters during midsummer and fall migration and for Arctic Village (Alaska) during midsummer. Arctic Village may experience reduced availability with early snowfalls in the fall, but we expect there to be little directional shift in the spring migration patterns. For the Bathurst Herd, we expect that fewer caribou would be exposed to the mines during the winter, while more caribou would be exposed to the combined Ekati and Diavik mining zone in the early summer and to the Lupin-Jericho mining zone during the fall migration. If changes in climate cause an increased presence of caribou in the mining sites, monitoring and mitigation measures may need to be intensified.

The results have implications for interpretation and management of disturbance in the landscape and highlight the need for longer-term studies to complement place-for-time substitutions.

Relative abundance of all nine life stages (eight larval stages and one adult stage) in the samples was determined. Furthermore, in 10 selected monthly samples, sex-ratio, relative abundance of three female maturity stages and number of eggs in uteri of ovigerous females were monitored. Nearly all life stages were present throughout the year and M. henricae is thus a perennial form in Lake Bathurst. Relative abundance of life stages suggests that M. henricae produces three successive generations per year. The spring generation, hatched from eggs laid during winter, matures around November-December. Its larval development takes between 4 and 5 months. The summer generation matures after a larval development of 2.5 months; this short period is ascribed to more favourable temperatures. The autumn generation takes about 4 months to mature.

Abstract (sommario):

The Bathurst Mining Camp (BMC) is one of Canada’s oldest mining districts for volcanogenic massive sulphide (VMS) deposits. Most of the 46 known deposits were discovered in the 1950s using a combination of geological and geophysical methods. However, renewed exploration efforts over the past 15 years have not been as successful as one would expect given the level of expenditure of the camp. Nevertheless, this has created a large database of high resolution airborne geophysical data (magnetics, electromagnetics, radiometrics, and full tensor gravity gradiometry) which makes Bathurst a unique case. We show data compilation and map view interpretation, followed by two-and-a-half-dimensional (2.5D) gravity and magnetic modelling. From this, we provide constraints on the folded structure of the mafic and felsic volcanic units, and we interpret a large gravity anomaly in the southeast as a possible ophiolite or a dense thick package of basaltic rocks. Finally, we show an example of 3D modelling in the northwestern part of the camp, where we combine map view interpretation with section-based modelling and 3D geophysical inversion.

Abstract (sommario):

The reported decline of the Bathurst herd has caused considerable concern and has raised rumours of a “crisis” in which there is a possibility of extinction. This paper reflects on relevant lessons learned from the officially declared “crisis” of population decline in 1955/56 and a second crisis of overpopulation identified by the author a decade later.

Abstract (sommario):

The Paulatuk – Bathurst Inlet region experienced rapid deglaciation in response to marine incursion across isostatically depressed terrain during high relative sea level stands. Marine limits, frequently defined by ice-contact deltas, range from 10 m asl in the west to 228 m asl in the east and were formed from approximately 12.5 to 9 ka BP, respectively. Seven relative sea level curves demonstrate that the mainland coast has shown initial rapid emergence, then progressively less emergence, and finally submergence from Paulatuk to Bernard Harbour during the late Holocene. Regions to the east (Richardson Bay to Bathurst Inlet) continue to experience emergence. Sea level curves have shown persistently higher rebound from west to east. The pattern and magnitude of observed postglacial sea level changes are in accord with theoretical predictions. In areas outside the glacial limit, as well as close to but within the glacial limit, relative sea level initially falls during the early and middle Holocene, and then begins to rise due to the migration of the forebulge in late Holocene times. Submergence becomes progressively younger from west to east. Closer to the centre of ice loading, emergence has progressed since deglaciation.

Abstract (sommario):

Harvest reporting has been in place for High Arctic muskoxen in Nunavut, Canada, since 1990-91. The communities of Resolute, Grise Fiord, and Arctic Bay harvest muskoxen in the region. Overall, muskox harvest has declined in Resolute and Grise Fiord since the 1990s. The recovery of Peary caribou populations on the Bathurst Island Complex, which provides an alternate preferred source of country food, may be a factor behind Resolute’s decreased muskox harvest. The proportion of harvest for domestic use has also declined relative to sport hunts, which have remained relatively constant since the 1990s. We compared muskox harvest from tag records and reported harvest, i.e., the voluntary surveys to the Nunavut Wildlife Harvest Study for muskoxen. It is clear that voluntarily reported harvest underestimates actual harvest, but not consistently enough to predict the actual harvest. Muskox populations are at historic high levels on Bathurst Island, southern Ellesmere Island, and Devon Island and could support more harvest than is currently taken. Changes to Total Allowable Harvests and management unit boundaries in 2015, combined with a decline in the availability of Baffin Island caribou as country food, may result in increased harvest pressure on muskoxen in the High Arctic.

Abstract (sommario):

This study evaluates whether a recent decline in snowcover extent for circumpolar regions is matched by changes in the seasonal streamflow regime of several small hillslope catchments on Bathurst and Melville Islands. This includes shifts in the timing of initiation, peak discharge and impacts on the spring–summer water budgets. Paired catchments (West and East) at the Cape Bounty Arctic Watershed Observatory (CBAWO) on Melville Island (74.9°N, 109.5°W) have been studied from the pre-snowmelt season to early August since 2003. They are low-rolling tundra catchments between 8.0 and 11.6 km2 in area. Likewise, within the Polar Bear Pass (PBP) watershed, Bathurst Island (75.7°N 98.7°W), two hillslope basins, Windy Creek (4.2 km2) and Landing Strip Creek (0.2 km2) have been investigated since 2007. Detailed snow surveys were conducted each spring and streamflow estimates were made using the mid-section velocity method. Nival regimes continue to dominate in these basins but runoff ratios are variable between catchments, across islands, and from year-to-year. In comparison to earlier streamflow studies across the Queen Elizabeth Islands (QEIs), an earlier response to peak discharge and start of flow for these hillslope streams is confirmed. Water budgets for PBP, CBAWO differ from other small Arctic watersheds.

Abstract (sommario):

The Endangered Maugean skate Zearaja maugeana is a relic species restricted to two isolated estuaries, Bathurst Harbour and Macquarie Harbour, in south-western Tasmania, Australia. Over a 1-year period, dive, tagging and net surveys provided information on the biology and ecology of this species. In all, 96 Maugean skates were caught during five trips to Macquarie Harbour, with four additional individuals observed underwater; however, no animals were located in the single trip to Bathurst Harbour. Morphometrics and the sex of the animals were recorded for 95 individuals. Crustaceans dominated the diet, with the majority of animals feeding on the crab Paragrapus gaimardii. Recapture rates were very low, with only one of 82 pit-tagged skates recaptured, and that occurred on the day of release. One acoustically tagged male skate was tracked for 5km along the harbour margin for 24h, whereas a female skate tracked for 46.5h showed high site fidelity, suggesting that multiple factors potentially influence habitat utilisation. Although Macquarie Harbour represents the stronghold for this species, this estuary is also experiencing major environmental disturbance and change. Conservation management of this Endangered skate requires specific consideration of aquaculture, recreational fishing and mine drainage effects, as well as ongoing monitoring.

Abstract (sommario):

ABSTRACTThe duration of survival of both the S and C strains ofMycobacterium aviumsubsp.paratuberculosisin feces was quantified in contrasting climatic zones of New South Wales, Australia, and detailed environmental temperature data were collected. Known concentrations of S and C strains in feces placed on soil in polystyrene boxes were exposed to the environment with or without the provision of shade (70%) at Bathurst, Armidale, Condobolin, and Broken Hill, and subsamples taken every 2 weeks were cultured for the presence ofM. aviumsubsp.paratuberculosis. The duration of survival ranged from a minimum of 1 week to a maximum of 16 weeks, and the provision of 70% shade was the most important factor in extending the survival time. The hazard of death for exposed compared to shaded samples was 20 and 9 times higher for the S and C strains, respectively. Site did not affect the survival of the C strain, but for the S strain, the hazard of death was 2.3 times higher at the two arid zone sites (Broken Hill and Condobolin) than at the two temperate zone sites (Bathurst and Armidale). Temperature measurements revealed maximum temperatures exceeding 60°C and large daily temperature ranges at the soil surface, particularly in exposed boxes.
