Australian Essential Oils History and Emerging Trends
Australian Essential Oils – History and Emerging Trends Ashley Dowell – Essential Oil Producers Association of Australia & Southern Cross University 23 rd October 2019 Introduction Australia has a unique flora largely of Gondwanan origin with later influence from the Indian subcontinent and South East Asia. Gondwana land was a pre-historic super continent including Australia, New Zealand, South America, Antarctica, Africa and the Indian sub-continent. Although separating early, it is proposed that Australia and India re-connected for a period of time before separating again. In more recent history Australia was connected to South-east Asia by land bridges which arose due to falling sea levels resulting from ice age glaciation Dominant plant families present in Australia include the essential oil bearing genus: Myrtaceae – Eucalyptus, Melaleuca, Leptospermum Rutaceae – Boronia, Citrus Other significant essential oil bearing plant families found in Australia are the Santalaceae, Myoporaceae, and Cupressaceae. Australia is often perceived as a land of deserts but is in fact a diverse collection of fire and drought adapted environments. Eucalypt woodlands make up to 39% of Australian vegetative cover, predominantly in New South Wales and Queensland followed by Hummock grasslands at 23% found mostly in Western Australia, Queensland and New SouthWales and Acacia woodlands occupying 10-20%, mostly in Western Australia, Queensland and New South Wales. There are significant areas of Acacia shrublands, Tussock grasslands and Chenopod shrubs and forblands, particularly in South Australia. There are relatively small (less than 70,000 Km2) but biologically significant areas of tropical and temperate rainforest in eastern coastal areas from Queensland to Tasmania, as well as Tall eucalypts forests and Callitris and Casuarina forests further inland and in sub-alpine areas.

Raya Bandung Sumedang KM 21, Jatinangor, Sumedang, Jawa Barat 45363 [email protected], [email protected] Diserahkan 29/06/2019, diterima 23/01/2020 ABSTRAK Tanaman obat telah menjadi alternatif pengobatan pada masyarakat lokal untuk beberapa penyakit. Banyaknya resistensi mikroba terhadap obat kimia yang meningkat memunculkan beberapa penelitian untuk beralih ke obat herbal yang memiliki efek samping yang lebih sedikit dibandingkan obat kimia. Tanaman dari genus Dysoxylum sangat tersebar luas di benua Asia, dan ada kurang kebih 80 spesies yang sudah diuji, dan masih ada banyak spesies tanaman genus ini yang belum diuji aktivitas farmakologinya. Berdasarkan kebutuhan yang ada, pengkajian terhadap tanaman-tanaman genus Dysoxylum perlu dilakukan agar dapat memberikan manfaat secara menyeluruh terhadap pengembangan obat herbal. Dari hasil ulasan diperoleh beberapa tanaman genus ini, didapat hasil aktivitasnya yang berupa sitotoksik terhadap sel kanker payudara MCF-7, antiinflamasi, antibakteri, antifidan, antiplasmodium, antioksidan, sitoprotektif dan penghambat pertumbuhan bakteri dan jamur yang berasal dari tanaman Dysoxylum aborescens, Dysoxylum parasiticum, Dysoxylum lukii, Dysoxylum alliaceum, Dysoxylum hainanense, Dysoxylum caulostachyum, Dysoxylum gothadora, Dysoxylum binectariferum, Dysoxylum cauliflorum, Dysoxylum densiflorum.

Final Report
Darwin Initiative Final Report To be completed with reference to the Reporting Guidance Notes for Project Leaders (http://darwin.defra.gov.uk/resources/) it is expected that this report will be a maximum of 20 pages in length, excluding appendices) Darwin project information Project reference 21-001 Project title Developing a conservation management plan for Samoa’s little dodo- the Manumea or tooth-billed pigeon Host country(ies) Samoa Contract holder institution The Australian National University Partner institution(s) The Samoa Conservation Society and the Samoan government, Birdlife, The Department of Conservation NZ, Auckland zoo Darwin grant value £229,842 Start/end dates of project 01 May 2014 – 31 December 2017 Project leader’s name Robert Heinsohn Project WWW.SAMOANBIRDS.ORG website/blog/Twitter @SAMOANBIRDS Report author(s) and date Robert Heinsohn 15/03/17 Project Rationale The Manumea or tooth-billed pigeon is found only on the islands of Samoa and has until recently been listed as Endangered by the IUCN. Recent surveys in upland and lowland forest on both Upolu and Savaii confirm that Manumea numbers are extremely small. The species was consequently upgraded to Critically Endangered. A major cyclone (cyclone Evan) in December 2012 is likely to have further affected Manumea and other native bird populations. It became vital that the locations of any remaining populations of Manumea be identified to inform the targeting of conservation efforts. As stated in the Manumea recovery plan (MNRE, 2006) it is also critical that information on the breeding biology and the spatial requirements of Manumea are understood so that threats can be identified and appropriate conservation management actions taken.

I Is the Sunda-Sahul Floristic Exchange Ongoing?
Is the Sunda-Sahul floristic exchange ongoing? A study of distributions, functional traits, climate and landscape genomics to investigate the invasion in Australian rainforests By Jia-Yee Samantha Yap Bachelor of Biotechnology Hons. A thesis submitted for the degree of Doctor of Philosophy at The University of Queensland in 2018 Queensland Alliance for Agriculture and Food Innovation i Abstract Australian rainforests are of mixed biogeographical histories, resulting from the collision between Sahul (Australia) and Sunda shelves that led to extensive immigration of rainforest lineages with Sunda ancestry to Australia. Although comprehensive fossil records and molecular phylogenies distinguish between the Sunda and Sahul floristic elements, species distributions, functional traits or landscape dynamics have not been used to distinguish between the two elements in the Australian rainforest flora. The overall aim of this study was to investigate both Sunda and Sahul components in the Australian rainforest flora by (1) exploring their continental-wide distributional patterns and observing how functional characteristics and environmental preferences determine these patterns, (2) investigating continental-wide genomic diversities and distances of multiple species and measuring local species accumulation rates across multiple sites to observe whether past biotic exchange left detectable and consistent patterns in the rainforest flora, (3) coupling genomic data and species distribution models of lineages of known Sunda and Sahul ancestry to examine landscape-level dynamics and habitat preferences to relate to the impact of historical processes. First, the continental distributions of rainforest woody representatives that could be ascribed to Sahul (795 species) and Sunda origins (604 species) and their dispersal and persistence characteristics and key functional characteristics (leaf size, fruit size, wood density and maximum height at maturity) of were compared.

Biogeography and Ecology in a Pantropical Family, the Meliaceae
Gardens’ Bulletin Singapore 71(Suppl. 2):335-461. 2019 335 doi: 10.26492/gbs71(suppl. 2).2019-22 Biogeography and ecology in a pantropical family, the Meliaceae M. Heads Buffalo Museum of Science, 1020 Humboldt Parkway, Buffalo, NY 14211-1293, USA. [email protected] ABSTRACT. This paper reviews the biogeography and ecology of the family Meliaceae and maps many of the clades. Recently published molecular phylogenies are used as a framework to interpret distributional and ecological data. The sections on distribution concentrate on allopatry, on areas of overlap among clades, and on centres of diversity. The sections on ecology focus on populations of the family that are not in typical, dry-ground, lowland rain forest, for example, in and around mangrove forest, in peat swamp and other kinds of freshwater swamp forest, on limestone, and in open vegetation such as savanna woodland. Information on the altitudinal range of the genera is presented, and brief notes on architecture are also given. The paper considers the relationship between the distribution and ecology of the taxa, and the interpretation of the fossil record of the family, along with its significance for biogeographic studies. Finally, the paper discusses whether the evolution of Meliaceae can be attributed to ‘radiations’ from restricted centres of origin into new morphological, geographical and ecological space, or whether it is better explained by phases of vicariance in widespread ancestors, alternating with phases of range expansion. Keywords. Altitude, limestone, mangrove, rain forest, savanna, swamp forest, tropics, vicariance Introduction The family Meliaceae is well known for its high-quality timbers, especially mahogany (Swietenia Jacq.).
