Insects of Macquarie Island. Introduction1
Pacific Insects 4 (4) : 905-915 December, 15, 1962 INSECTS OF MACQUARIE ISLAND. INTRODUCTION1 By J. Linsley Gressitt BISHOP MUSEUM, HONOLULU Abstract: Collections of land arthropods were made on Macquarie Island by J. L. Gres sitt and J. H. Calaby, 4-10 December 1960, and by Keith Watson, December 1960-Decem- ber 1961. This paper is a brief discussion of the geography and environment of Macquarie, introductory to the systematic papers describing the fauna. Watson, of the Australian Na tional Antarctic Research Expeditions, will later publish his general ecological studies, when the species are all identified. INTRODUCTION This paper is a brief description of the geography and environment of Macquarie Is land, as related to land arthropods. It is presented by way of introduction to the series of reports by various specialists on the land arthropod fauna of the island. The bulk of these reports immediately follow this article. (One Macquarie mite is discussed in the third of the preceding articles by Wallwork on Antarctic mites, and another is mentioned in his second article.) Others will appear in later issues, when they are completed. After publication of the bulk of these taxonomic reports, Keith Watson will publish his general report on the land arthropod fauna of Macquarie, incorporating his ecological studies on the fauna. Through the kindness of Mr. P. G. Law, Director of the Antarctic Division, Australian Department of External Affairs, I was permitted to join the Australian National Antarctic Research Expedition for the annual resupply trip to Macquarie Island in early December 1960. The operation, supported by the chartered Danish ice-breaker Magga Dan, was car ried on at Macquarie from 4th to lOth December. -
JOURNAL Number Six
THE JAMES CAIRD SOCIETY JOURNAL Number Six Antarctic Exploration Sir Ernest Shackleton MARCH 2012 1 Shackleton and a friend (Oliver Locker Lampson) in Cromer, c.1910. Image courtesy of Cromer Museum. 2 The James Caird Society Journal – Number Six March 2012 The Centennial season has arrived. Having celebrated Shackleton’s British Antarctic (Nimrod) Expedition, courtesy of the ‘Matrix Shackleton Centenary Expedition’, in 2008/9, we now turn our attention to the events of 1910/12. This was a period when 3 very extraordinary and ambitious men (Amundsen, Scott and Mawson) headed south, to a mixture of acclaim and tragedy. A little later (in 2014) we will be celebrating Sir Ernest’s ‘crowning glory’ –the Centenary of the Imperial Trans-Antarctic (Endurance) Expedition 1914/17. Shackleton failed in his main objective (to be the first to cross from one side of Antarctica to the other). He even failed to commence his land journey from the Weddell Sea coast to Ross Island. However, the rescue of his entire team from the ice and extreme cold (made possible by the remarkable voyage of the James Caird and the first crossing of South Georgia’s interior) was a remarkable feat and is the reason why most of us revere our polar hero and choose to be members of this Society. For all the alleged shenanigans between Scott and Shackleton, it would be a travesty if ‘Number Six’ failed to honour Captain Scott’s remarkable achievements - in particular, the important geographical and scientific work carried out on the Discovery and Terra Nova expeditions (1901-3 and 1910-12 respectively). -

Introduction Rushes (family Juncaceae) are a common component of New Zealand wetland vegetation and species within this family appear very similar. With over 50 species, Juncus are the largest component of the New Zealand rushes and are notoriously difficult for amateurs and professionals alike to identify to species level. This key and accompanying factsheets have been developed to enable users with a diverse range of botanical expertise to identify Juncus to species level. The best time for collection, survey or identification is usually from December to April as mature fruiting material is required to distinguish between species. -
ACT, Australian Capital Territory
Biodiversity Summary for NRM Regions Species List What is the summary for and where does it come from? This list has been produced by the Department of Sustainability, Environment, Water, Population and Communities (SEWPC) for the Natural Resource Management Spatial Information System. The list was produced using the AustralianAustralian Natural Natural Heritage Heritage Assessment Assessment Tool Tool (ANHAT), which analyses data from a range of plant and animal surveys and collections from across Australia to automatically generate a report for each NRM region. Data sources (Appendix 2) include national and state herbaria, museums, state governments, CSIRO, Birds Australia and a range of surveys conducted by or for DEWHA. For each family of plant and animal covered by ANHAT (Appendix 1), this document gives the number of species in the country and how many of them are found in the region. It also identifies species listed as Vulnerable, Critically Endangered, Endangered or Conservation Dependent under the EPBC Act. A biodiversity summary for this region is also available. For more information please see: www.environment.gov.au/heritage/anhat/index.html Limitations • ANHAT currently contains information on the distribution of over 30,000 Australian taxa. This includes all mammals, birds, reptiles, frogs and fish, 137 families of vascular plants (over 15,000 species) and a range of invertebrate groups. Groups notnot yet yet covered covered in inANHAT ANHAT are notnot included included in in the the list. list. • The data used come from authoritative sources, but they are not perfect. All species names have been confirmed as valid species names, but it is not possible to confirm all species locations. -

Freshwater Fish in the Falklands
Freshwater fish in the Falklands Conservation of native zebra trout Echo Goodwin, North Arm School A report by Katherine Ross to the Falkland Islands Government and Falklands Conservation, 2009. Summary • Only two species of freshwater fish, Zebra trout (Aplochiton zebra) and Falklands minnows (Galaxias maculatus) are native to the Falklands. • Brown trout (Salmo trutta) were introduced to the Falklands in the 1940’s and 1950’s. They can spend part of their life cycle at sea which has allowed them to spread across the islands causing a catastrophic decline in the distribution of zebra trout. The ways by which brown trout remove zebra trout probably include predation on juvenile fish and competition for food. • Zebra trout are long lived and therefore adult populations may persist for many years where juveniles no longer survive. Such populations can become extinct suddenly. • Freshwater fish of the Falklands were last surveyed in 1999. • This project investigated the distribution of freshwater fish in West and East Falkland by electrofishing, netting and visual surveys and identified conservation priorities for zebra trout. • Zebra trout populations were found in Lafonia, the south of West Falkland and Port Howard. Brown trout were found across much of Lafonia where their range appears to have expanded since 1999. • Once brown trout have invaded a catchment they are very difficult to remove. Controlling the spread of brown trout is therefore an urgent priority if zebra trout are to be conserved. • Freshwater habitats where zebra trout were found were generally in good condition but in some areas perched culverts may prevent juvenile zebra trout from returning to freshwaters (we think larval zebra trout spend their first few months at sea). -

Muell. (Asteraceae: Senecioneae) Ekaterina D. Malenkova, Lyudmila V. Ozerova, Ivan A. Schanzer & Alexander C. Timonin Summary: Analyses of ITS1-2 data from a comprehensive sample of African succulent species of Senecio and related genera reveals that Senecio tropaeolifolius, though closely related to S. oxyriifolius, should be treated as a separate species. According to our results, it may be one of the parental species to S. kleiniiformis, a widely cultivated ornamental of uncertain hybrid origin. Keywords: Asteraceae, Senecioneae, taxonomy, systematics, Senecio kleiniiformis, ITS1-2 Senecio tropaeolifolius MacOwan ex F. Muell. is a widely cultivated succulent ornamental (Brickell 2003) whose taxonomic rank has remained uncertain so far. Its similarity to S. oxyriifolius DC. was mentioned in its first description (Mueller 1867) and Rowley (1994, 2002) rendered it as a subspecies of the latter one. However, Jeffrey (1986, 1992) treated these allopatric (Fig. 1) taxa, S. tropaeolifolius and S. oxyriifolius, as two separate species in the section Peltati. According to their descriptions, these two species differ mainly in their growth form, the number of involucral bracts of the capitula, the number of florets in the capitula, the presence/absence of ray florets and bristles on cypselae. All these characters are rather variable amongSenecio L. s. latiss. and their taxonomic value is questionable. Molecular data drastically changed the understanding of taxonomy and phylogeny of Senecio and related genera (Pelser et al. -

Important Bird Areas South Georgia Andrew Clarke, John P. Croxall, Sally Poncet, Anthony R. Martin and Robert Burton n o s r a e P e c u r B South Georgia from the sea; a typical first view of the island. Abstract The mountainous island of South Georgia, situated in the cold but productive waters of the Southern Ocean, is a UK Overseas Territory and one of the world’s most important seabird islands. It is estimated that over 100 million seabirds are based there, while there may have been an order of magnitude more before the introduction of rats. South Georgia has 29 species of breeding bird, and is the world’s most important breeding site for six species (Macaroni Penguin Eudyptes chrysolophus , Grey-headed Albatross Thalassarche chrysostoma , Northern Giant Petrel Macronectes halli , Antarctic Prion Pachyptila desolata , White-chinned Petrel Procellaria aequinoctialis and Common Diving Petrel Pelecanoides urinatrix ). Several of the key species are globally threatened or near-threatened, which emphasises the need for action to improve the conservation status of the island’s birds. South Georgia is currently classified by BirdLife International as a single Important Bird Area (IBA) but it may be better considered as comprising several distinct IBAs. Current threats to the South Georgia avifauna include rats (a major campaign to eliminate rats began in 2010/11), regional climate change, and incidental mortality in longline and trawl fisheries. Local fisheries are now well regulated but South Georgia albatrosses and petrels are still killed in large numbers in more distant fisheries. 118 © British Birds 105 • March 2012 • 118 –144 South Georgia This paper is dedicated to the memory of Peter Prince (1948–1998), who worked on South Georgia from 1971. -
