Description of this Water Source and its Dependent Ecosystems 3.1 General The Tindall Limestone Aquifer is the oldest of three geological formations that comprise the Daly Sedimentary Basin and spans beneath the catchments of the Daly and Roper Rivers as shown in Map 1. Water from the Tindall aquifer discharges into many of the river systems within these catchments, including the Katherine, Flora, Douglas and Roper Rivers.

In the central part of the Daly groundwater basin where the Tindall Aquifer is at considerable depth, only minor flow is considered to occur. The aquifer is unconfined in places around the basin margin, where it outcrops close to the surface. As described in section 3.1, the Tindall Aquifer is largely confined by younger geologic formations. Recharge is highest in the unconfined areas and negligible where it is confined by the Jinduckin Formation. Recharge can be redu ced in the unconfined area where overlying cretaceous rocks are present. Discharge zones are mainly located along the major rivers and comprise both karstic springs and more diffuse streambed discharge. The sections along the Katherine River where discharge from the Tindall Aquifer is known to occur are shown in Map 4.

Ten diagnosable taxa were identified using allozyme profiles at 45 presumptive loci. Chelodina expansa, C. parkeri, C. rugosa and C. burrungandjii are in a Group A clade, C. longi- collis, C. novaeguineae, C. steindachneri, C. pritchardi and C. mccordi are in a Group B clade, and C. oblonga is in a monotypic Group C clade, with each clade thought to represent a distinct subgenus. Chelodina siebenrocki is syn- onymised with C. rugosa. An eleventh taxon, C. reimanni, could not be distinguished from C. novaeguineae on the basis of allozyme profiles, but it is morphologically distinct. Its status is therefore worthy of further investigation. Three instances of natural hybridization were detected. Chelodina rugosa and C. novaeguineae hybridize in the Gulf country of Queensland, with evidence of backcrossing to C. novaeguineae. Chelodina longicollis and C. novaeguineae hybridize in central coastal Queensland, and C. rugosa and C. burrungandjii hybridize along their zone of contact in the plateau escarpment streams and pools.

  • In Ngukurr: a Remote Australian Aboriginal Community
    Understanding ‘Work’ in Ngukurr: A Remote Australian Aboriginal Community Eva McRae-Williams (BA, BBH, MA) September 2008 Thesis submitted in fulfilment of the requirements for: Doctor of Philosophy (Anthropology) Charles Darwin University Statement of Authorship Except where referenced in the text of the research project, this dissertation contains no material published elsewhere or extracted in whole or part from a thesis or report by me for another degree or diploma. No other person’s work has been used without due acknowledgement in the main text of the dissertation. The dissertation has not been submitted for the award of any other degree or diploma in any other tertiary institution. Eva McRae-Williams Date: ……………… ii Abstract This thesis is an ethnographic study of the ‘work’ ideologies inherent in a remote Australian Aboriginal community; Ngukurr in South East Arnhem Land of the Northern Territory. Formerly known as the Roper River Mission and established in 1908, it is today home to approximately 1000 Aboriginal inhabitants. Fieldwork for this project was conducted in three phases between 2006 and 2007 totalling seven months. The aim of this research was to gain an insight into the meaning and value of ‘work’ for Aboriginal people in Ngukurr. First, this involved acknowledging the centrality of paid employment to mainstream western ‘work’ ideology and its influence on my own, and other non-Aboriginal peoples, understandings and ways of being in the world. Through this recognition the historical and contemporary relationship between Aboriginal and non-Aboriginal people in the northern part of Australia, specifically the Roper River region, was found to be fundamentally shaped by labour relations and dominant western ‘work’ ideology.

  • Threatened Species Survey Report For
    Threatened species ‘likelihood of occurrence’ assessment This ‘likelihood of occurrence’ assessment identifies which threatened species have potential to occur within the project footprint. The following procedure was used to determine the likelihood of occurrence of threatened species: 1) Identify potential habitat features within the project footprint using available desktop information (i.e. land unit mapping, existing vegetation mapping, aerial imagery, fire history etc.). 2) Identify: a. Matters of National Environmental Significance obtained using the Protected Matters Search Tool (undertaken January 2017). b. Bioregional threatened species records extracted from the NT flora and fauna atlases maintained by DENR. 3) Collate the following details for each of those species – conservation status (NT and Federal), habitat requirements, distribution and number of records within the bioregions. 4) Analyse the likelihood that each species will occur in the project footprint by applying the following likelihood classifications: a. HIGH – it is expected that this species will be within the project footprint because of the presence of core suitable habitat, and/or there are recent proximate records (i.e. post-2000). b. MEDIUM – this species may occur within the project footprint; however, there is evidence that lowers its likelihood of occurrence (i.e. lack of core habitat, no recent records with the search area, habitat degradation etc.). c. LOW – it is not expected that this species is supported within the project footprint, as there is no suitable habitat for the species and/or current threats in the region are known to have significantly impacted upon the species. d. NONE – there is strong evidence that this species will not occur within the project footprint.

    Vol. 17: 63–71, 2012 ENDANGERED SPECIES RESEARCH Published online April 12 doi: 10.3354/esr00417 Endang Species Res Mitochondrial variation among Australian freshwater turtles (genus Myuchelys), with special reference to the Endangered M. bellii Darren Fielder1,*, Karl Vernes1, Erika Alacs2, Arthur Georges2 1Ecosystem Management, University of New England, Armidale, New South Wales 2351, Australia 2Institute for Applied Ecology, University of Canberra, Australian Capital Territory 2601, Australia ABSTRACT: Identifying species and the relationships among them remains important for assess- ing biodiversity trends and is a critical focus for reversing global biodiversity loss. The saw-shelled turtles of Australia, in the genus Myuchelys, show cryptic diversity and include species that range from Endangered (M. bellii), through those that are locally abundant but extremely limited in dis- tribution (M. georgesi and M. purvisi) to those that are common and widespread (M. latisternum). The Endangered M. bellii is restricted to 3 small isolated populations in the headwaters of the Murray-Darling basin, in the Border, Gwydir and Namoi tributaries. There is no evidence of strong differentiation among these 3 populations based on mitochondrial DNA (mtDNA) diver- gences; rather there is only a shallow genetic structure ranging from 0.1 to 0.3% divergence. The 3 restricted and small populations of the Endangered M. bellii face a number of threatening pro- cesses and require conservation management across state boundaries as a single biological spe- cies. The mtDNA phylogeny supports previous phylogenetic findings of a deep phylogenetic divergence between M. purvisi and M. georgesi (13.5% mtDNA) and the sister taxa relationship of M. latisternum and M.

Page a,*, Kristina von Rintelen b, Jane M. Hughes a a Australian Rivers Institute, Faculty of Environmental Sciences, Griffith University, Nathan Campus, Qld., 4111, Australia b Museum of Natural History, Humboldt-University Berlin, Invalidenstrasse 43, D-10115, Berlin, Germany Received 3 May 2006; revised 5 August 2006; accepted 8 August 2006 Available online 18 August 2006 Abstract Mitochondrial DNA sequences were used to investigate phylogenetic and biogeographic relationships among Australian freshwater shrimp from the genus Caridina H. Milne Edwards, 1837 (Atyidae) and congeners from potential source populations throughout the Indo-West Pacific region. Numerous Australian taxa have close evolutionary relationships with non-Australian taxa from locations throughout the region, indicating a diverse origin of the Australian freshwater fauna. This implies many colonisations to or from Aus- tralia over a long period, and thus highlights the surprising adeptness of freshwater shrimp in dispersal across ocean barriers and the unity of much of the region’s freshwater biota. Interestingly, a study on Australia’s other main genus of atyid shrimp, Paratya Miers, 1882, inferred only a single colonisation. A number of potential species radiations within Australia were also identified. This agrees with patterns detected for a large number of Australian freshwater taxa, and so implies a vicariant explanation due to the development of colder, dryer climates during the late Miocene/early Pliocene.

  • Classification of Australian Tropical Rivers to Predict Climate Change Impacts
    Classification of Australian Tropical Rivers to Predict Climate Change Impacts Wayne ErskineA,C,M.J. Saynor B and J LowryB ACentre for the Sustainable Use of Coasts and Catchments, School of Environmental and Life Sciences, The University of Newcastle, PO Box 127, Ourimbah, NSW 2258, Australia. BEnvironmental Research Institute of the Supervising Scientist, GPO Box 461, Darwin, NT 0801, Australia CCorresponding author; email: [email protected] Abstract. The preliminary typology of Australian tropical rivers proposed by Erskine et al. (2005) was applied to the complete channel network (named and major rivers) shown on the 1:250,000 topographic maps for three large drainage basins in northern Australia (Daly River, NT; Fitzroy River, WA; Flinders River, Qld) using remotely sensed data, topographic and geologic maps and relevant published literature. This work is part of the Tropical Rivers Inventory and Assessment Project funded by Land and Water Australia. Significantly this is the first time that the whole channel network of all three rivers has been classified into homogeneous river reaches based on geomorphic criteria. Previous river classification exercises on these rivers have only investigated a minor component of the total channel network. The nine river types of Erskine et al. (2005) were revised by additions, amalgamations and deletions to 12 to accommodate the full range of river types present. The 12 river types mapped as homogeneous river reaches were: (1) bedrock rivers; (2) confined and constrained rivers; (3) low sinuosity rivers; (4) meandering rivers; (5) wandering rivers; (6) anabranching rivers; (7) chain of ponds; (8) gullies; (9) floodouts; (10) lakes, swamps or billabongs; (11) non-channelised valley floors; and (12) estuarine rivers.
