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. -

Department of Sustainability, Environment, Water, Population and Communities; Formerly from Department of Primary Industries, Parks, Water and Environment (Tasmania)
The Minister included this species in the critically endangered category, effective from 26/02/2013. Advice to the Minister for Sustainability, Environment, Water, Population & Communities from the Threatened Species Scientific Committee (the Committee) on amendment to the list of Threatened Species under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) 1. Reason for Conservation Assessment by the Committee This advice follows assessment of information gathered through the Commonwealth’s partnership agreement with Tasmania, which is aimed at systematically reviewing species that are inconsistently listed under the EPBC Act and relevant Tasmanian legislation. The Committee provides the following assessment of the appropriateness of this species’ inclusion in the EPBC Act list of threatened species: Corybas sulcatus (grooved helmet-orchid) 2. Summary of Species Details Taxonomy Conventionally accepted as Corybas sulcatus (M.A.Clem. & D.L.Jones) G.N.Backh. Formerly Nematoceras sulcatum M.A.Clem. & D.L.Jones. State/Territory Listing This species is listed as endangered (as Nematoceras Status sulcatum) under the Tasmanian Threatened Species Protection Act 1995. Description A small, deciduous, tuberous terrestrial orchid that forms small clonal colonies. Leaves are solitary, circular (12–20 mm diameter) and flat to shallowly concave. They are light green above and silvery green beneath, with a thick-textured blade and fleshy leaf stalk 12–16 mm long. Flowers are 25–30 mm long and 10–14 mm wide, mostly dark red and held erect on a fleshy, green stalk that is 5–7 mm long (Clements and Jones, 2007). Distribution The grooved helmet-orchid is endemic to Macquarie Island (Tasmania). -

H. & SEPPELT, R. D. 2002. Resupinate fungi (Basidiomycetes, Aphyllophorales) of Macquarie Island, Australia. Hikobia 13: 745-750. Fourteen collections of resupinate higher fungi in the order Aphyllophorales (Basidiomycetes) were made on Subantarctic Macquarie Island (54°30'S, 158°57' E) in 1995. Of the 14, three proved to lack species-determining characteristic basidiospores and 12 were determined to belong to three species in two genera; Athelopsis lembospora (Bourdot) Oberwinkler, Athelopsis subinconspicua (Lirschauer) Julich, the first report of this species from the Southern Hemisphere, and Epithele galzinii Bres., the first reportr of E. galzinii from an Australian territory and also representing a southern range extension by several hundred kilometers. None are endemic and all are suspected to have reached the Island by long-distance transoceanic wind dispersal from other southern continental sources. Their habitats are restricted to old and clustered culms, frond bracts, and leaf petioles of the fern Polystichum vestitum (G. Forst.) C. Presl, the raised pedestals of old giant russock grass stem bases of Poa foliosa (Hook. f-) Hook. f., and the woody, but thin, stems of Acaena magellanica (Lam.)

Patterns of flammability across the vascular plant phylogeny, with special emphasis on the genus Dracophyllum A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of philosophy at Lincoln University by Xinglei Cui Lincoln University 2020 Abstract of a thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of philosophy. Abstract Patterns of flammability across the vascular plant phylogeny, with special emphasis on the genus Dracophyllum by Xinglei Cui Fire has been part of the environment for the entire history of terrestrial plants and is a common disturbance agent in many ecosystems across the world. Fire has a significant role in influencing the structure, pattern and function of many ecosystems. Plant flammability, which is the ability of a plant to burn and sustain a flame, is an important driver of fire in terrestrial ecosystems and thus has a fundamental role in ecosystem dynamics and species evolution. However, the factors that have influenced the evolution of flammability remain unclear. -

Joseph Hooker first learned that Charles Darwin believed in the transmuta- tion of species in 1844. For the next 14 years, Hooker remained a "nonconsenter" to Darwin's views, resolving to keep the question of species origin "subservient to Botany instead of Botany to it, as must be the true relation." Hooker placed particular emphasis on the need for any theory of species origin to support the broad taxonomic delimitation of species, a highly contentious issue. -

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). -
