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. -

Not a tree or shrub was to be seen, no not even big enough to make a toothpick. I landed in three different places, displayed our Colours and took possession of the Country in his Majestys name under a descharge of small arms. Our Botanists found here only three plants, the one is a coarse strong bladed grass which grows in tufts, Wild Burnet and a Plant like Moss which grows on the rocks".

THE ALPINE FLORA of TIERRA DEL FUEGO by D. M. MOORE
Anal. Inst. Bot. Cavanilles 32 (2): 419-440 (1975) THE ALPINE FLORA OF TIERRA DEL FUEGO by D. M. MOORE This paper is dedicated to Prof. S, Rivas Goday on his 70th birthday. Introduction Since the first known collection of Fuegian plants, made along^ the NW coast of Tierra del Fuego by George Handisyd in 1690 (More- ton-Middleton, 1909; Gunckel, 1971), more than 200 collectors have contributed to our knowledge of the flora of this region (Moore and Goodall, unpub.). Because of the importance of shipborne expeditions, most of the earlier studies were confined to coastal areas and fuller information on the interior did not become available until the expe ditions of Nordenskjold (Dusen, 1900), Skottsberg (1916) and Roivai- nen (1954) during the late 19th and early 20th centuries. Since then there has, of course, been a continued accumulation of data on the flora and vegetation of Tierra del Fuego so that now, although many problems remain, the general characteristics are fairly clear. The mountainous regions of Tierra del Fuego are generally difficult of access and have uncertain and inclement weather so that even today many parts have not been visited by botanists. However, the travels of Alboff (1896, 1897), Dusen (1900), Gusinde (Skottsberg, 1926) and Skottsberg (1916) served to outline the general features of the alpine flora and these have been confirmed and amplified by more recent studies (Godley, 1960; Moore, 1969, 1970, 1971, etc; Moore and Goodall, 1973, 1974, etc.). In consequence, despite the inevitable lacunae in our knowledge, it seems appropriate to summarize current information on the alpine flora of Tierra del Fuego and this paper represents the first such attempt since that of Skottsberg (1916). -

THE VEGETATION of SUBANTARCTIC CAMPBELL ISLAND ______Summary: the Vegetation of Campbell Island and Its Offshore Islets Was Sampled Quantitatively at 140 Sites
COLIN D. MEURK, M.N. FOGGO1 and J. BASTOW WILSON2 123 Landcare Research - Manaaki Whenua, PO Box 69, Lincoln, New Zealand. 1. Department of Science, Central Institute of Technology, Private Bag 39807, Wellington, New Zealand. 2. Botany Department, University of Otago, PO Box 56, Dunedin, New Zealand. THE VEGETATION OF SUBANTARCTIC CAMPBELL ISLAND __________________________________________________________________________________________________________________________________ Summary: The vegetation of Campbell Island and its offshore islets was sampled quantitatively at 140 sites. Data from the 134 sites with more than one vascular plant species were subjected to multivariate analysis. Out of a total of 140 indigenous and widespread adventive species known from the island group, 124 vascular species were recorded; 85 non-vascular cryptogams or species aggregates play a major role in the vegetation. Up to 19 factors of the physical environment were recorded or derived for each site. Agglomerative cluster analysis of the vegetation data was used to identify 21 plant communities. These (together with cryptogam associations) include: maritime crusts, turfs, megaherbfields, tussock grasslands, and shrublands; mid-elevation swamps, flushes, bogs, tussock grasslands, shrublands, dwarf forests, and induced meadows; and upland tundra-like tussock grasslands, tall and short turf-herbfields, bogs, flushes, rock-ledge herbfields, and fellfields. Axis 1 of the DCA ordination is largely a soil gradient related to the eutrophying impact of marine spray, sea mammals and birds, and nutrient flushing. Axis 2 is an altitudinal (or thermal) gradient. Axis 3 is related to soil reaction and to different kinds of animal influence on vegetation stature and species richness, and Axis 4 also appears to have fertility and animal associations. -
Entomology of the Aucklands and Other Islands South of New Zealand: Introduction1
Pacific Insects Monograph 27: 1-45 10 November 1971 ENTOMOLOGY OF THE AUCKLANDS AND OTHER ISLANDS SOUTH OF NEW ZEALAND: INTRODUCTION1 By J. L. Gressitt2 and K. A. J. Wise3 Abstract: The Aucklands, Bounty, Snares and Antipodes are Southern Cold Temperate (or Low Subantarctic) islands south of New Zealand and north of Campbell I and Macquarie I. The Auckland group is the largest of all these islands south of New Zealand, and has by far the largest fauna. The Snares, Bounty and Antipodes, though farther north, are quite small islands with limited fauna. These islands have vegetation dominated by tussock grass, bogs with sedges and cryptogams, and shrubs at lower altitudes and in some cases forests of Metrosideros or Olearia near the shores, usually in more protected environments. Bounty Is have almost no vegetation. These islands are breeding places for many sea birds and for hair seals and fur seals. The insect fauna of the Aucklands numbers several hundred species representing most major orders of insects and other land arthropods. This is the introductory article to the first volume treating the land arthropod fauna of the Auckland, Snares, Bounty and Antipodes Islands. The Auckland Islands (SOHO' S; 166° E) form the largest island group south of New Zealand and Australia. Among other southern cold temperate and subantarctic islands they are only exceeded in area by the Falkland Is, South Georgia, Kerguelen and Tierra del Fuego. In altitude they are lower than South Georgia, Tierra del Fuego, Tristan da Cunha, Gough, Marion, Kerguelen, Crozets and Heard, and very slightly lower than the Falklands. -

Photo: Jeremy Rolfe. New Zealand Threat Classification Series is a scientific monograph series presenting publications related to the New Zealand Threat Classification System (NZTCS). Most will be lists providing NZTCS status of members of a plant or animal group (e.g. algae, birds, spiders). There are currently 23 groups, each assessed once every 3 years. After each 3-year cycle there will be a report analysing and summarising trends across all groups for that listing cycle. From time to time the manual that defines the categories, criteria and process for the NZTCS will be reviewed.
