The King Island Natural Resource Management Group provided the opportunity and funding to turn a dream into reality at least for the fauna of King Island. This book provides information on the ecology and conservation management of invertebrate and vertebrate fauna of terrestrial and freshwater habitats of King Island. The book is a companion volume to The native vegetation of King Island, Bass Strait, the King Island Flora – a field guide and the Field guide to Tasmanian birds. We intended to write a book that served as a guide to fauna identi- fication and management and distribute it to all land owners and managers of King Island and land management agencies so it had to be written in a readable style. Most of the chapters are written by scientists so it soon became apparent that with limited time and budget it was difficult to write both a field guide and a technical book to suit everyone. The main aims of the book are to synthesise published information and recent survey data on the fauna of King Island, to provide guidelines for conservation management of fauna, and to encourage land managers to identify vertebrate fauna and fill in the gaps on the distribution and abundance of fauna. Chapter 1, the Introduction, provides a brief summary of the island’s location, climate, geology, soils and land use history. Chapter 2 describes the main native vegetation communities and Chapter 3 describes streams and wetlands of King Island and their macroin- vertebrates based on recent surveys of the freshwater systems. Chapter 4 describes the ecology of terrestrial invertebrates of pastures and various types of native vegetation, and highlights their habitat requirements and management. Chapter 5 summarises the ecology and biogeography of the vertebrate fauna: freshwater fish, frogs, reptiles, birds and mammals. Chapter 6 highlights the role and habitat needs of the fauna of old growth eucalypt forests with a focus on birds and insects. Chapter 7 presents and interprets recent survey data on forest birds, identifies threatened and declining birds and their habitats, provides guidelines on habitat management for fauna and specifies action to recover threatened and declining species. Chapter 8 serves as a field guide to the vertebrates of King Island and gives accounts of all the species of freshwater fish, frogs, reptiles, mammals and most of the resident and regular visiting birds with cross-references to the plates. Plants have co-evolved with animals and together they form an interconnected web of life. The health of native vegetation depends on many different fauna. This book will be useful to vii any land managers and advisors with a desire to discover King Island’s fauna and their habitat needs and manage native vegetation for fauna. The book doesn’t pretend to be a complete fauna guide but it does provide a foundation for present and future action to protect the biodiversity of King Island. There is an urgent need on King Island to continue fauna surveys and monitoring and to recover threatened and declining species, especially birds. Little is known of the invertebrates of King Island, so we hope that this book, especially the inverte- brate chapter, references and websites, will stimulate King Islanders and others to collect, identify and document the invertebrates of King Island. Richard Donaghey July 2003 viii Acknowledgments he observations and publications of naturalists such as Dr Bob Green, Max McGarvie and Tothers provided the foundation for this fauna guide. We are indebted to the landholders of King Island for their interest, hospitality and access to their remnant vegetation for conducting biodiversity surveys. The future of King Island’s fauna is in their hands. Richard Donaghey enjoyed the company of Graeme Batey and Nigel Burgess in rediscovering scrubtits. The Bushcare program enabled Richard Donaghey and Richard Barnes to visit King Island many times for conservation extension.

  • Commonwealth Listing Advice on Alpine Sphagnum Bogs And
    Advice to the Minister for the Environment, Heritage and the Arts from the Threatened Species Scientific Committee (the Committee) on Amendments to the List of Ecological Communities under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) 1. Summary of conservation assessment by the Committee This advice follows the assessment of information provided by a nomination to list the Alpine Bog Community as a threatened ecological community. The nomination was made available for public exhibition and comment for a period of two months. The Committee had regard to all public and expert comments that were relevant to the survival of the ecological community. The Committee judges that the ecological community has been demonstrated to have met sufficient elements of: • Criterion 2 to make it eligible for listing as endangered; • Criterion 3 to make it eligible for listing as endangered; and • Criterion 4 to make it eligible for listing as endangered. 2. Name of the ecological community A nomination was received for the Alpine Bog Community. Alpine bogs are commonly found in the vicinity of alpine fens, and have been identified as being dependent on these (VSAC, 1991a). In order to make identification easier in the field, to recognise the importance of Sphagnum species to alpine bogs, and to acknowledge the interdependency of alpine bogs, fens and the natural drainage lines that connect them, the Committee recommends that the name of the ecological community be changed to the “Alpine Sphagnum Bogs and Associated Fens” ecological community. 3. Description The Alpine Sphagnum Bogs and Associated Fens ecological community generally has sharp boundaries and is easily delineated from other alpine vegetation communities.

    Vegetation Benchmarks Rainforest and related scrub Eucryphia lucida Vegetation Condition Benchmarks version 1 Rainforest and Related Scrub RPW Athrotaxis cupressoides open woodland: Sphagnum peatland facies Community Description: Athrotaxis cupressoides (5–8 m) forms small woodland patches or appears as copses and scattered small trees. On the Central Plateau (and other dolerite areas such as Mount Field), broad poorly– drained valleys and small glacial depressions may contain scattered A. cupressoides trees and copses over Sphagnum cristatum bogs. In the treeless gaps, Sphagnum cristatum is usually overgrown by a combination of any of Richea scoparia, R. gunnii, Baloskion australe, Epacris gunnii and Gleichenia alpina. This is one of three benchmarks available for assessing the condition of RPW. This is the appropriate benchmark to use in assessing the condition of the Sphagnum facies of the listed Athrotaxis cupressoides open woodland community (Schedule 3A, Nature Conservation Act 2002).

The local Government resident population at the 2016 census was 906 and rose 16 % between the last two censuses. The Flinders Island Tourism & Business Inc. (FITBI)represents 70 members across retail, tourism, fishing and agriculture. It plays a key role in developing the visitor economy through marketing to potential visitors as well as attracting residents to the island. In 2016, FITBI launched a four-year marketing program. The Flinders Island Airport at Whitemark is the gateway to the island. It has been owned by the Flinders Council since hand over by the Commonwealth Government in the early 1990’s. Being a remote a community the airport is a critical to the island from a social and economic point of view. It’s the key connection to Tasmania (Launceston) and Victoria. The local residents must use air transport be that for health or family reasons. The high cost of the air service impacts on the cost of living as well as discouraging visitors to visit the island. It is particularly hard for low income families. The only access via sea is with the barge, Matthew Flinders 11, operated by Furneaux Freight out of Bridport. This vessel has very basic facilities for passengers and takes 8hours one way.

AHLQUIST Departmentof Biologyand PeabodyMuseum of Natural History,Yale University, New Haven, Connecticut 06511 USA ABSTRACT.--OldWorld starlingshave been thought to be related to crowsand their allies, to weaverbirds, or to New World troupials. New World mockingbirdsand thrashershave usually been placed near the thrushesand/or wrens. DNA-DNA hybridization data indi- cated that starlingsand mockingbirdsare more closelyrelated to each other than either is to any other living taxon. Some avian systematistsdoubted this conclusion.Therefore, a more extensiveDNA hybridizationstudy was conducted,and a successfulsearch was made for other evidence of the relationshipbetween starlingsand mockingbirds.The resultssup- port our original conclusionthat the two groupsdiverged from a commonancestor in the late Oligoceneor early Miocene, about 23-28 million yearsago, and that their relationship may be expressedin our passerineclassification, based on DNA comparisons,by placing them as sistertribes in the Family Sturnidae,Superfamily Turdoidea, Parvorder Muscicapae, Suborder Passeres.Their next nearest relatives are the members of the Turdidae, including the typical thrushes,erithacine chats,and muscicapineflycatchers.

  • The Mcguire Center for Lepidoptera and Biodiversity
    Supplemental Information All specimens used within this study are housed in: the McGuire Center for Lepidoptera and Biodiversity (MGCL) at the Florida Museum of Natural History, Gainesville, USA (FLMNH); the University of Maryland, College Park, USA (UMD); the Muséum national d’Histoire naturelle in Paris, France (MNHN); and the Australian National Insect Collection in Canberra, Australia (ANIC). Methods DNA extraction protocol of dried museum specimens (detailed instructions) Prior to tissue sampling, dried (pinned or papered) specimens were assigned MGCL barcodes, photographed, and their labels digitized. Abdomens were then removed using sterile forceps, cleaned with 100% ethanol between each sample, and the remaining specimens were returned to their respective trays within the MGCL collections. Abdomens were placed in 1.5 mL microcentrifuge tubes with the apex of the abdomen in the conical end of the tube. For larger abdomens, 5 mL microcentrifuge tubes or larger were utilized. A solution of proteinase K (Qiagen Cat #19133) and genomic lysis buffer (OmniPrep Genomic DNA Extraction Kit) in a 1:50 ratio was added to each abdomen containing tube, sufficient to cover the abdomen (typically either 300 µL or 500 µL) - similar to the concept used in Hundsdoerfer & Kitching (1). Ratios of 1:10 and 1:25 were utilized for low quality or rare specimens. Low quality specimens were defined as having little visible tissue inside of the abdomen, mold/fungi growth, or smell of bacterial decay. Samples were incubated overnight (12-18 hours) in a dry air oven at 56°C. Importantly, we also adjusted the ratio depending on the tissue type, i.e., increasing the ratio for particularly large or egg-containing abdomens.
