  • Hydrogeological Overview of Springs in the Great Artesian Basin
    Hydrogeological Overview of Springs in the Great Artesian Basin M. A. (Rien) Habermehl1 Abstract The Great Artesian Basin (GAB) is a regional groundwater system consisting of aquifers and confining beds within the sedimentary Eromanga, Surat and Carpentaria Basins. They under- lie arid to semi-arid regions across 1.7 million km2, or one-fifth of the Australian continent. Artesian springs of the GAB are naturally occurring outlets of groundwater from the confined aquifers. Springs predominantly occur near the eastern recharge margins and the south-western and western discharge margins of the GAB. These zones of natural groundwater discharge represent areas of permanent water, with widely recognised cultural, spiritual and subsistence importance to Indigenous people for tens of thousands of years. The unique hydrogeological environments – discharge, hydrochemistry and substrate – support a range of endemic flora and fauna protected under the EPBC Act (1999). Springs have formed in many areas across the GAB; however, the largest concentrations occur near the south-western margins of the basin. Supporting these flowing artesian springs is a multi-layered aquifer system, comprising Jurassic- to Cretaceous-age sandstones and siltstone, and confining beds of mudstones. Hydrogeological, hydrochemical and isotope hydrology studies show that most artesian springs and flowing water bores in the GAB derive their water from the main Jurassic–Lower Cretaceous Cadna-owie Formation – Hooray Sandstone aquifer and its equivalents. Focusing on springs in South Australia, this paper provides a summary of the hydrogeology of the GAB, including zones of recharge and regional groundwater flow directions, with a major focus on summarising under- standing of the occurrence and formation of springs.

    Desert Rivers – the ‘boom and bust’ country The Lake Eyre Basin occupies one-seventh of the Australian continent. It is a wide and shallow basin, created by forces deep in the Earth’s mantle.

  • Australia's Place in the Cosmopolitan World of Indo-West Pacific
    Molecular Phylogenetics and Evolution 43 (2007) 645–659 www.elsevier.com/locate/ympev An island in the stream: Australia’s place in the cosmopolitan world of Indo-West Pacific freshwater shrimp (Decapoda: Atyidae: Caridina) Timothy J. 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.
