  • Species of the Box-Gum Woodlands and Derived Native Grasslands
    White Box-Yellow Box-Blakely’s Red Gum Grassy Woodland and Derived Native Grassland Ecological Community Species List White Box-Yellow Box-Blakely’s Red Gum Grassy Woodland and Derived Native Grassland Ecological Community Species List This species list is designed to provide information about plant species that can be found in the White Box-Yellow Box-Blakely’s Red Gum Grassy Woodland and Derived Native Grassland ecological community listed under the Environment Protection and Biodiversity Conservation Act 1999. The species list was developed to complement the Listing Information Guide, and should be read in that context. It provides information on scientific and common names of the species, the kind of plant the species is, whether it is an ‘important’ species for the purposes of this ecological community and whether it is exotic or native, perennial or annual. The list is not exhaustive and not all of the species listed will occur in every patch of White Box-Yellow Box-Blakely’s Red Gum Grassy Woodland and Derived Native Grassland. If there are any species that you think should be added to the list, removed from the list, or that are categorised incorrectly, please contact [email protected]. As such, this document may change over time and you should check that you are referring to the most recent version of the list. Caveat: This list has been compiled from a range of sources. While reasonable efforts have been made to ensure the accuracy of the information, no guarantee is given, nor responsibility taken, by the Commonwealth for its accuracy, currency or completeness.

  • Global Seagrass Distribution and Diversity: a Bioregional Model ⁎ F
    Journal of Experimental Marine Biology and Ecology 350 (2007) 3–20 www.elsevier.com/locate/jembe Global seagrass distribution and diversity: A bioregional model ⁎ F. Short a, , T. Carruthers b, W. Dennison b, M. Waycott c a Department of Natural Resources, University of New Hampshire, Jackson Estuarine Laboratory, Durham, NH 03824, USA b Integration and Application Network, University of Maryland Center for Environmental Science, Cambridge, MD 21613, USA c School of Marine and Tropical Biology, James Cook University, Townsville, 4811 Queensland, Australia Received 1 February 2007; received in revised form 31 May 2007; accepted 4 June 2007 Abstract Seagrasses, marine flowering plants, are widely distributed along temperate and tropical coastlines of the world. Seagrasses have key ecological roles in coastal ecosystems and can form extensive meadows supporting high biodiversity. The global species diversity of seagrasses is low (b60 species), but species can have ranges that extend for thousands of kilometers of coastline. Seagrass bioregions are defined here, based on species assemblages, species distributional ranges, and tropical and temperate influences. Six global bioregions are presented: four temperate and two tropical. The temperate bioregions include the Temperate North Atlantic, the Temperate North Pacific, the Mediterranean, and the Temperate Southern Oceans. The Temperate North Atlantic has low seagrass diversity, the major species being Zostera marina, typically occurring in estuaries and lagoons. The Temperate North Pacific has high seagrass diversity with Zostera spp. in estuaries and lagoons as well as Phyllospadix spp. in the surf zone. The Mediterranean region has clear water with vast meadows of moderate diversity of both temperate and tropical seagrasses, dominated by deep-growing Posidonia oceanica.

    Chestnut-backed Button-quail in the north was a bonus, showing brilliantly for a long time – unheard of for this family (Andy Jensen) WESTERN AUSTRALIA 5/10 – 27 SEPTEMBER 2017 LEADER: ANDY JENSEN ASSISTANT: STUART PICKERING ! ! 1 BirdQuest Tour Report: Western Australia (including Christmas Island) 2017 www.birdquest-tours.com Western Shrike-tit was one of the many highlights in the southwest (Andy Jensen) Western Australia, if it were a country, would be the 10th largest in the world! The BirdQuest Western Australia (including Christmas Island) 2017 tour offered an unrivalled opportunity to cover a large portion of this area, as well as the offshore territory of Christmas Island (located closer to Indonesia than mainland Australia). Western Australia is a highly diverse region with a range of habitats. It has been shaped by the isolation caused by the surrounding deserts. This isolation has resulted in a richly diverse fauna, with a high degree of endemism. A must visit for any birder. This tour covered a wide range of the habitats Western Australia has to offer as is possible in three weeks, including the temperate Karri and Wandoo woodlands and mallee of the southwest, the coastal heathlands of the southcoast, dry scrub and extensive uncleared woodlands of the goldfields, coastal plains and mangroves around Broome, and the red-earth savannah habitats and tropical woodland of the Kimberley. The climate varied dramatically Conditions ranged from minus 1c in the Sterling Ranges where we were scraping ice off the windscreen, to nearly 40c in the Kimberley, where it was dust needing to be removed from the windscreen! We were fortunate with the weather – aside from a few minutes of drizzle as we staked out one of the skulkers in the Sterling Ranges, it remained dry the whole time.

Daru) Running head: Phylogenetic regionalization of seagrasses 1 Abstract While our knowledge of species distributions and diversity in the terrestrial biosphere has increased sharply over the last decades, we lack equivalent knowledge of the marine world. Here, we use the phylogenetic tree of seagrasses along with their global distributions and a metric of phylogenetic beta diversity to generate a phylogenetically-based delimitation of marine phytoregions (phyloregions). We then evaluate their evolutionary affinities and explore environmental correlates of phylogenetic turnover between them. We identified 11 phyloregions based on the clustering of phylogenetic beta diversity values. Most phyloregions can be classified as either temperate or tropical, and even geographically disjunct temperate regions can harbor closely related species assemblages.
