  • Journal of a Voyage Around Arnhem Land in 1875
    JOURNAL OF A VOYAGE AROUND ARNHEM LAND IN 1875 C.C. Macknight The journal published here describes a voyage from Palmerston (Darwin) to Blue Mud Bay on the western shore of the Gulf of Carpentaria, and back again, undertaken between September and December 1875. In itself, the expedition is of only passing interest, but the journal is worth publishing for its many references to Aborigines, and especially for the picture that emerges of the results of contact with Macassan trepangers along this extensive stretch of coast. Better than any other early source, it illustrates the highly variable conditions of communication and conflict between the several groups of people in the area. Some Aborigines were accustomed to travelling and working with Macassans and, as the author notes towards the end of his account, Aboriginal culture and society were extensively influenced by this contact. He also comments on situations of conflict.1 Relations with Europeans and other Aborigines were similarly complicated and uncertain, as appears in several instances. Nineteenth century accounts of the eastern parts of Arnhem Land, in particular, are few enough anyway to give another value. Flinders in 1802-03 had confirmed the general indications of the coast available from earlier Dutch voyages and provided a chart of sufficient accuracy for general navigation, but his contact with Aborigines was relatively slight and rather unhappy. Phillip Parker King continued Flinders' charting westwards from about Elcho Island in 1818-19. The three early British settlements, Fort Dundas on Melville Island (1824-29), Fort Wellington in Raffles Bay (1827-29) and Victoria in Port Essington (1838-49), were all in locations surveyed by King and neither the settlement garrisons nor the several hydrographic expeditions that called had any contact with eastern Arnhem Land, except indirectly by way of the Macassans.

  • A New Freshwater Catfish (Pisces: Ariidae) from Northern Australia
    Rec. West. Aust. Mus. 1988,14(1): 73-89 A new freshwater catfish (Pisces: Ariidae) from northern Australia PatriciaJ. Kailola* and Bryan E. Pierce* Abstract A new species of fork-tailed catfish is described on the basis of 31 specimens collected in northern Australia between the Fitzroy River (Western Australia) and the Mitchell River (Queensland). Arius midgleyi sp. novo grows to at least 1.3 m TL and is distinguished from other Australo-Papuan ariids by a combination of charac­ ters including snout shape, barbel length, eye size, tooth arrangement and gill raker number and position. Comparison is made with other ariid species occurring in northern Australian rivers, including the morphologically similar A. leptaspis (Bleeker). Introduction The Timor Sea and Gulf of Carpentaria drainage systems (Lake 1971) approx­ imately represent the Leichhardtian zoogeographic region of Whitley (1947). The rainfall pattern in this region is dominated by the wet monsoon (occurring within the period November to April). Most rivers here traverse a flat coastal plain about 15 km wide before reaching the sea (Lake 1971). These rivers commonly possess wide flood plains and low gradients, often contracting to a chain of waterholes during the dry season; some (Gregory River; Fitzroy to Daly Rivers) have reaches of rapids or very deep gorges. The average annual discharge from this region is 69000 billion litres (Lake 1971), most of it occurring during the wet season. Five of Australia's 18 species of fork-tailed catfishes (Ariidae) are common in this northern region, yet were overlooked by Whitley (1947) and Iredale and Whitley (1938). The members of this family, which is distributed circumglobally in the tropics and subtropics, may inhabit the sea, rivers within tidal influence, or fresh waters.

The Djalubu was placed upright in the ground on the south west edge of the current lake. A cormorant of the Dhalwangu clan flew from Gan Gan towards Gapuwiayk and when it approached, its wings hit the water and turned it into a big lake.

  • The Successful Biological Control of Spinyhead Sida, Sida Acuta [Malvaceae], by Calligrapha Pantherina (Col: Chrysomelidae) in Australia’S Northern Territory
    Proceedings of the X International Symposium on Biological Control of Weeds 35 4-14 July 1999, Montana State University, Bozeman, Montana, USA Neal R. Spencer [ed.]. pp. 35-41 (2000) The Successful Biological Control of Spinyhead Sida, Sida Acuta [Malvaceae], by Calligrapha pantherina (Col: Chrysomelidae) in Australia’s Northern Territory GRANT J. FLANAGAN1, LESLEE A. HILLS1, and COLIN G. WILSON2 1Department of Primary Industry and Fisheries, P.O. Box 990, Darwin, Northern Territory 0801, Australia 2Northern Territory Parks and Wildlife Commission P.O. Box 496, Palmerston, Northern Territory 0831, Australia Abstract Calligrapha pantherina Stål was introduced into Australia from Mexico as a biologi- cal control agent for the important pasture weed Sida acuta Burman f. (spinyhead sida). C. pantherina was released at 80 locations in Australia’s Northern Territory between September 1989 and March 1992. It established readily at most sites near the coast, but did not establish further inland until the mid to late 1990’s. Herbivory by C. pantherina provides complete or substantial control in most situations near the coast. It is still too early to determine its impact further inland. Introduction The malvaceous weed Sida acuta (sida) Burman f. (Kleinschmidt and Johnson, 1977; Mott, 1980) frequently dominates improved pastures, disturbed areas and roadsides in northern Australia. This small, erect shrub is native to Mexico and Central America but has spread throughout the tropics and subtropics (Holm et al., 1977). Chinese prospectors, who used the tough, fibrous stems to make brooms (Waterhouse and Norris, 1987), may have introduced it into northern Australia last century. Today it is widespread in higher rainfall areas from Brisbane in Queensland to the Ord River region of Western Australia.

It now only remains in a few areas, with northern Australia being the main stronghold. Previous work using a single mitochondrial gene approach suggested the existence of regional barriers to gene flow in northern Australia. In this study, whole mitochondrial sequences of 92 P. pristis from 7 river drainages across northern Australia were used to refine the population structure. This approach revealed barriers to gene flow at a scale as fine as between adjacent river drainages.

  • Coomalie Planning Concepts and Land Use Objectives 2000 Supports the Northern Territory Government’S Vision for Coomalie for the Next 20 to 25 Years
    Department of Lands, Planning and Environment Foreword Part 1 - Planning Concepts of Coomalie Planning Concepts and Land Use Objectives 2000 supports the Northern Territory Government’s vision for Coomalie for the next 20 to 25 years. The Planning Concepts provide the direction and stimulus for public and private developers and the consent authority. This should facilitate the development of Coomalie in a manner which preserves its rural nature while recognising opportunities for continued development at a sustainable level. Part 1 - Planning Concepts provides the background information to Part 2 - Land Use Objectives. The Batchelor Division of the Northern Territory Planning Authority has been directed, and it is intended that any future Coomalie consent authority will be directed, to take the Planning Concepts into account along with those matters listed under the Planning Act 1993, when considering a development application. Part 2 - Land Use Objectives of Coomalie Planning Concepts and Land Use Objectives 2000 contains the land use objectives which have formal status by virtue of declaration under section 8(1) of the Act. Part 2 - Land Use Objectives establishes the framework for planning control within the Coomalie Sub- Region. To achieve this, land use objectives are provided under Key Objectives for the entire Sub-Region and under Land Use Objectives for specific land uses. The general discussion of issues assists in interpreting and implementing the objectives. The Coomalie Planning Concepts and Land Use Objectives 2000 aim to provide a co-ordinated and strategic approach to land use planning in Coomalie. In due course, the NT Planning Scheme Coomalie will apply to the entire Coomalie Sub-Region and parts of this Scheme will translate the land use objectives into planning practice.

The new species is highly distinctive among its congeners in having the dactylus of pereiopod 5 similar to the dactyli of pereiopods 3–4 and lacking the comb-like row of spiniform setae typical of the genus. The branchial formula is also distinctive for the genus in lacking an arthrobranch at the base of pereiopod 1 and in having a vestigial epipod on maxilliped 1. Despite the distinctive morphology of the new species, the molecular data did not provide strong support for the recognition of a new genus.
