    Pacific Plate Biogeography, with Special Reference to Shorefishes VICTOR G. SPRINGER m SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY • NUMBER 367 SERIES PUBLICATIONS OF THE SMITHSONIAN INSTITUTION Emphasis upon publication as a means of "diffusing knowledge" was expressed by the first Secretary of the Smithsonian. In his formal plan for the Institution, Joseph Henry outlined a program that included the following statement: "It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in all branches of knowledge." This theme of basic research has been adhered to through the years by thousands of titles issued in series publications under the Smithsonian imprint, commencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series: Smithsonian Contributions to Anthropology Smithsonian Contributions to Astrophysics Smithsonian Contributions to Botany Smithsonian Contributions to the Earth Sciences Smithsonian Contributions to the Marine Sciences Smithsonian Contributions to Paleobiology Smithsonian Contributions to Zoo/ogy Smithsonian Studies in Air and Space Smithsonian Studies in History and Technology In these series, the Institution publishes small papers and full-scale monographs that report the research and collections of its various museums and bureaux or of professional colleagues in the world cf science and scholarship. The publications are distributed by mailing lists to libraries, universities, and similar institutions throughout the world. Papers or monographs submitted for series publication are received by the Smithsonian Institution Press, subject to its own review for format and style, only through departments of the various Smithsonian museums or bureaux, where the manuscripts are given substantive review.

  • MVG04 Tropical Eucalypt Open Forests DRAFT
    MVG 4 - TROPICAL EUCALYPT OPEN FORESTS Tropical eucalypt savanna forest Kakadu National Park, NT (Photo: D. Keith) Overview Also known as tropical savannas. MVG 4 occurs in high rainfall areas of Cape York in Queensland, on Melville and Bathurst Islands, the Top End in Northern Territory, and in Western Australia close to Kimberley coast. Structurally it is an open forest with a tall grass-dominated groundlayer. Dominated by eucalypts, primarily species of Corymbia and Eucalyptus, notably the subgenera Fibridia and Leprolaena, but the tree canopy also includes a range of tropical non-eucalypt genera. The grassy understorey is dominated by annual and perennial species exclusively with C4 photosynthetic pathways. Closely associated with tropical monsoonal climates with wet summers and dry winters. Regularly fire-prone in dry seasons. Facts and figures Major Vegetation Group MVG 4 – Tropical Eucalypt Open Forests Major Vegetation Subgroups xx. Tropical eucalypt savanna forest NT, QLD, WA (number of NVIS descriptions) Typical NVIS structural formations Low open forest Number of IBRA regions 26 Most extensive in IBRA region Est. pre-1750: Jarrah Forest (WA) (Est. pre-1750 and present) Present: Nandewar (NSW) Estimated pre-1750 extent (km2) 4 726 Present extent (km2) 3 952 Area protected (km2) 1 417 Structure and physiognomy Open forests dominated by eucalypts with tall grass dominated understories. Trees are taller with straighter boles and the canopy cover is greater than in the savanna woodlands of MVG 12. Leaves of the tree canopies are sclerophyllous and vary in size from notophyll (20 – 45 cm2) to mesophyll (45 – 150 cm2). Broad-leaved shrubs, palms and cycads occur in the understorey (Dunlop 2001; Beard et al.

  • Rapid Creek Species Lists
    NATIVE VEGETATION SPECIES The Rapid Creek Landcare Group compiled these lists to inform revegetation work. The habitat based lists include a range of species that are appropriate to be planted in the catchment. The following references were used: • Rapid Creek Management Plan (1994) Prepared for Darwin City Council and Greening Australia by Clouston • Terrestrial Flora and Fauna Surveys of Darwin International Airport (2009) Prepared for NT Airports by EcOz Environmental Services • Rapid Creek Vegetation Survey Prepared by Clark and Brocklehurst in the early 1990’s • Expert botanical advice A focus is placed on tree and shrub species likely to be used in revegetation. It is recommended site specific expert advice be sought before finalising species lists for particular projects.

  • BIODIVERSITY CONSERVATION on the TIWI ISLANDS, NORTHERN TERRITORY: Part 1. Environments and Plants
    BIODIVERSITY CONSERVATION ON THE TIWI ISLANDS, NORTHERN TERRITORY: Part 1. Environments and plants Report prepared by John Woinarski, Kym Brennan, Ian Cowie, Raelee Kerrigan and Craig Hempel. Darwin, August 2003 Cover photo: Tall forests dominated by Darwin stringybark Eucalyptus tetrodonta, Darwin woollybutt E. miniata and Melville Island Bloodwood Corymbia nesophila are the principal landscape element across the Tiwi islands (photo: Craig Hempel). i SUMMARY The Tiwi Islands comprise two of Australia’s largest offshore islands - Bathurst (with an area of 1693 km 2) and Melville (5788 km 2) Islands. These are Aboriginal lands lying about 20 km to the north of Darwin, Northern Territory. The islands are of generally low relief with relatively simple geological patterning. They have the highest rainfall in the Northern Territory (to about 2000 mm annual average rainfall in the far north-west of Melville and north of Bathurst). The human population of about 2000 people lives mainly in the three towns of Nguiu, Milakapati and Pirlangimpi. Tall forests dominated by Eucalyptus miniata, E. tetrodonta, and Corymbia nesophila cover about 75% of the island area. These include the best developed eucalypt forests in the Northern Territory. The Tiwi Islands also include nearly 1300 rainforest patches, with floristic composition in many of these patches distinct from that of the Northern Territory mainland. Although the total extent of rainforest on the Tiwi Islands is small (around 160 km 2 ), at an NT level this makes up an unusually high proportion of the landscape and comprises between 6 and 15% of the total NT rainforest extent. The Tiwi Islands also include nearly 200 km 2 of “treeless plains”, a vegetation type largely restricted to these islands.
