Will Climate Change, Genetic and Demographic Variation Or Rat Predation Pose the Greatest Risk for Persistence of an Altitudinally Distributed Island Endemic?

Received: 3 September 2012; in revised form: 29 October 2012 / Accepted: 16 November 2012 / Published: 23 November 2012 Abstract: Species endemic to mountains on oceanic islands are subject to a number of existing threats (in particular, invasive species) along with the impacts of a rapidly changing climate. The Lord Howe Island endemic palm Hedyscepe canterburyana is restricted to two mountains above 300 m altitude. Predation by the introduced Black Rat (Rattus rattus) is known to significantly reduce seedling recruitment. We examined the variation in Hedyscepe in terms of genetic variation, morphology, reproductive output and demographic structure, across an altitudinal gradient. -
How Sympatric Is Speciation in the Howea Palms of Lord Howe Island?

Population genetic and ecological data are necessary to provide a more coherent and comprehensive understanding of this emerging model system. Here, we analyse data on abundance, juvenile recruitment, pollination mode and genetic variation and structure in both species. We find that Howea forsteriana is less abundant than Howea belmoreana. The genetic data based on amplified fragment length polymorphisms markers indicate similar levels of variation in the two species, despite the estimated census population size of H. belmoreana being three times larger than that of H. forsteriana. Genetic structure within species is low although some weak isolation by distance is detectable. -

Conservation Issues for the Vascular Flora of Lord Howe Island
490 Cunninghamia 8(4): 2004 Auld & Hutton, Plant conservation on Lord Howe Island Conservation issues for the vascular flora of Lord Howe Island Tony D. Auld1 and Ian Hutton2 1Biodiversity and Conservation Science Section, Department of Environment and Conservation (NSW) PO Box 1967 Hurstville NSW 2220, AUSTRALIA Email: [email protected] 2PO Box 157 Lord Howe Island, NSW 2898 AUSTRALIA Abstract: The flora of the Lord Howe Island Group (31°30’S, 159°05’E) comprises a unique mix of elements of Australian, New Zealand and New Caledonian floras. It is significant for its high degree of endemism and for its structural and biological (leaves, flowers, fruit) role in supporting a diverse array of fauna. Conservation of this flora is dependant upon: reducing current habitat degradation (mostly the result of exotic weeds); minimising any future impacts, in particular the effects of climate change on the unique cloud forests of the southern mountains and the continued introduction and spread of weeds and the pathogen Phytophthora cinnamomi. We provide a description of the nature of the major threats to the flora and suggest an area-based scheme, focussed on the relative conservation significance of remaining vegetation, as a mechanism for developing priorities for threat mitigation activities. While a number of threat control works are in place, eg. weed control, some re-emphasis is needed. In addition, some new initiatives are required including: reducing the rate of introductions of new exotics; a system to remove potential environmental weeds from the settlement area; phytosanitary guidelines; pathogen quarantine measures; search and removal of environmental weeds from remote areas; and ex situ initiatives for plant species restricted to the cloud forests of the southern mountains. -

Baron Ferdinand Von Mueller
PALM S Dowe: Ferdinand von Mueller’s Palms Vol. 61(1) 2017 Baron Ferdinand von Mueller, the “Princeps of JOHN LESLIE DOWE Australian Tropical Australian Herbarium, James Cook University, Botany,” and a Smithfield, Qld 4878, Australia Historical [email protected] Account of his Australasian Palms Baron Ferdinand von Mueller was Australia’s most celebrated botanist of the nineteenth century. Although a broad-based plant taxonomist, he described 19 new palm taxa, including two genera and 15 species in Australia, and one species each in New Guinea and Fiji. Significantly, Mueller’s taxa represent about 25% of all the palms thus far recognized for Australia and its off-shore dependencies, and he remains the single most important taxonomist to have worked on Australian palms. Baron Ferdinand von Mueller (1825–96) (Fig. His vast correspondence, estimated to be over 1) was Australia’s most productive plant 12000 surviving letters (Anon. 2015), and taxonomist of the nineteenth century (Stevens capacity to publish and disseminate widely his 1997), describing over 2400 taxa of which taxonomic work (Churchill et al. 1978), more than half remain as the currently used provide an extensive resource upon which to names (APNI 2015). Migrating from Germany understand his botanical methods and resolve to Australia in 1847, Mueller was engaged as his continuing taxonomic influence. The the Victorian Government Botanist in 1853 (a appellation “ Princeps of Australian Botany ” was position he held until his death) and first given to him by William Thiselton-Dyer, established the Phytologic Museum of Director of Kew Gardens, in recognition of his Melbourne (now the National Herbarium of pre-eminence as a taxonomist and champion Victoria) in the Melbourne Botanic Gardens.
