At the Workshop the organizers gave a commitment to produce proceedings of the Workshop. Essentially it was intended that the proceedings would cover the talks and respond to the issues raised in discussion at the Workshop. It was planned that this would be done by the end of 1998. Over the next three years, a series of unforeseen events delayed the production of the proceedings. To some extent this delay was fortuitous as it allowed a series of topics and issues to be further researched. These are outlined below. • Work in progress at the time of the workshop could be completed and/or developed. This is particularly evident in the paper on variation in Tuart. At the time of the workshop David Coates was unable to reference specific genetic data for Tuart. Since the workshop David and Linda Broadhurst were able to begin this work and present their results in this publication. Other contributors were able to expand on their work, often in collaboration with others. An example of this is the paper by Robert Powell and Bronwen Keighery. • A more thorough response to the topics, issues and questions raised in the open discussion session was possible. This has been done through both - a direct response paper: ‘Tuart Issues - Responses to the Questions and Issues Raised at the Workshop’ and - the papers: ‘The Distribution and Conservation of Tuart and the Community with which it Lives’ and ‘Floristics of the Tuart Forest Reserve’. • Improved integration of the written papers. As a consequence, the publication is somewhat different than what was planned at the workshop, hence the name change. The Workshop : Tuart ( Eucalyptus gomphocephala ) - the tree and the community with which it lives On Saturday 21st March 1998 the Wildflower Society of Western Australia - Perth Branch, in co- operation with the Departments of Conservation and Land Management (Wildlife Research Centre) and Environmental Protection (Conservation Branch) organized a one day seminar/workshop on Tuart - the tree and the community with which it lives . The topic of the Workshop arose as: • Tuart is an endemic of the Swan Coastal Plain where most of the people in WA live; • Tuart is typical of many of the communities growing in coastal areas from Busselton to Jurien; • Tuart grows in a variety of communities from the forests of Busselton to scattered groves near Jurien; and • the conservation of Tuart and its community is vital to conservation on the Swan Coastal Plain. Several months before the Workshop, a flier was distributed to a variety of groups and state and local government bodies. This advertising was very successful and the Workshop was booked out a week in advance. Participants at the Workshop listed the following sources/contacts when they were asked how they had heard of the workshop - Ecoplan News, South West Environment Centre, 1 Tuart ( Eucalyptus gomphocephala) and Tuart Communities WA Naturalists Club, Wildflower Society Flier, Ecoplan Workshop, Landcare Magazine, Greening WA Leaflet, Swan Catchment Centre notice board, Department of Conservation and Land Management (CALM) volunteer newsletter and personal contact. The high level of response to the limited advertising indicated that there was a high interest in Tuart. Around seventy people registered for Workshop. These people are listed below. Several people were unable to attend on the day. George Babarskas Ric How Barbara Backhouse Brian James Bob Backhouse Bronwen Keighery Jim Barrow Greg Keighery Lin Barrow Jan King Bernhard Bischoff Ian Lantzke Marion Blackwell Patricia Lantzke Charles Broadbent Brendan Lepschi Kate Brown Janice Marshall Norma Calcutt Gary McMahon Don Cameron Neil McMulkin Cheryl Campbell Karen McRoberts Ben Carr Ellen Miguel Kevin Chia Tom Mitchell David Coates Brian Moyle Ann Cochrane Michael Norman Margaret Collins Margo O’Byrne Dianna Corbyn Dorothy Perret Jo Darbyshire Hywel Phillips Mitchell Davies Suzanne Robertson John Dell Robin Roe Glynne Dyer Katinka Ruthrof Charles Evans Lesley Shaw Eitan Friedman Carolyn Switzer Gerry Gauntlett Claire Thorstensen Judith Gauntlett Challis Tilbrook Keryn Gear Bill Tyler Neil Gibson Maxine Tyler Mary Gray David Wake Ann Gunness Neil Walker Claire Hall Rose Walker John Harris Andrew Webb Alison Hearn Beth Weir Griselda Hitchcock Nick Woolfrey Steve Hopper Colin Yates Participants came from across the range of Tuart, from Jurien to Busselton. Friends Groups, landholders, local government, industry, CALM, Kings Park, the Department of Environmental Protection and Conservation and Land Management and the WA Museum were all represented at the Workshop. The Workshop went from 10am to 3.30pm and was held in the Tuart woodland at the CALM Wildlife Research Centre at Woodvale. Before lunch, expert speakers presented papers on the nature of variation in the Tuart species, the biology of Tuart, the variety of communities in which Tuart grows and the flora and fauna of Tuart communities. After lunch Tuart reserve managers from the community and government briefly addressed Tuart management issues. A workshop discussion session followed in which the participants of the workshop were invited to comment on issues raised by the speakers, present their own issues and question any of the speakers. Bronwen Keighery chaired the morning session and Margo O’Byrne the afternoon session. Displays on Tuart at Mt Henry, Bunbury and Bold Park were mounted in the Wildlife Research 2 Tuart ( Eucalyptus gomphocephala) and Tuart Communities Centre Library. The setting of the centre, a delightful day, delicious morning and afternoon teas and lunches, fine speakers and willing participants ensured that the workshop was a success. ACKNOWLEDGEMENTS With such a long gestation, this publication has relied on the encouragement and support of many people. So, finally now that this book is published we wish to thank the following individuals and groups. • The people who registered for, and participated in the workshop. These people were listed on the previous page. • Presenters of the papers at the workshop. We are fortunate in this state, as there are many generous people in the community of biologists who are happy to share their areas of expertise with the interested community. All of the speakers at the Workshop enthusiastically responded to the initial request to prepare a talk and were erudite and knowledgeable on the day. The presenters are indicated on the Program over the page. • The authors of the papers The authors are listed on the Contents page. The papers also contain individual acknowledgment sections. • The Workshop Committee: Barbara and Bob Backhouse, Lin and Jim Barrow, Neil Gibson, Claire Hall, Alison Hearn, Bronwen, Greg, Kristin and Sarah Keighery, Brian Moyle and Beth Weir. A particular thanks to Barbara Backhouse who typed some of Bronwen’s Workshop notes and proof read most of the papers. • People were not involved in the workshop but have volunteered time and expertise to the project: David Longman, Kelly Rylander, Sandra Santich and Nick Casson. Special mention should be made of David Longman’s invaluable computer support. • The Departments of Conservation and Land Management and Environmental Protection who supported the workshop and the production of this book. • The Department of Conservation and Land Management

Ruthrof, Giles St. J. Hardy Centre of Excellence for Climate Change Woodland and Forest Health, Murdoch University, Perth, Australia Email: [email protected] Received June 7th, 2012; revised July 10th, 2012; accepted July 25th, 2012 Ecosystems in Mediterranean climate regions are projected to undergo considerable changes as a result of shifting climate, including from extreme drought and heat events. A severe and sudden dieback event, occurring in regionally significant Eucalyptus gomphocephala woodland in Western Australia, coincided with extreme drought and heat conditions in early 2011. Using a combination of remote sensing and field- based approaches, we characterized the extent and severity of canopy dieback following the event, as well as highlighted potential predisposing site factors. An estimated 500 ha of woodland was severely affected between February and March 2011. Tree foliage rapidly discolored and died over this period. In the af- fected portion of the woodland, approximately 90% of trees greater than 20 cm DBH were impacted, while in the adjacent unaffected woodland 6% showed signs of damage. Tree density in the unaffected area had approximately 4.5 times more trees than the affected woodland. Precipitation drainage patterns are thought to explain the difference between affected and unaffected woodland.

Pollination is achieved by sexual deception insect. Their colours, for instance, are usually dull shades of the male wasp, which is flung over and upside down of green, yellow and maroon and they are usually, but against the column when it attempts to fly off with the not always, odourless to humans.

  • II. a Cladistic Analysis of Rbcl Sequences and Morphology
    Systematic Botany (2003), 28(2): pp. 270±292 q Copyright 2003 by the American Society of Plant Taxonomists Phylogenetic Relationships in the Commelinaceae: II. A Cladistic Analysis of rbcL Sequences and Morphology TIMOTHY M. EVANS,1,3 KENNETH J. SYTSMA,1 ROBERT B. FADEN,2 and THOMAS J. GIVNISH1 1Department of Botany, University of Wisconsin, 430 Lincoln Drive, Madison, Wisconsin 53706; 2Department of Systematic Biology-Botany, MRC 166, National Museum of Natural History, Smithsonian Institution, P.O. Box 37012, Washington, DC 20013-7012; 3Present address, author for correspondence: Department of Biology, Hope College, 35 East 12th Street, Holland, Michigan 49423-9000 ([email protected]) Communicating Editor: John V. Freudenstein ABSTRACT. The chloroplast-encoded gene rbcL was sequenced in 30 genera of Commelinaceae to evaluate intergeneric relationships within the family. The Australian Cartonema was consistently placed as sister to the rest of the family. The Commelineae is monophyletic, while the monophyly of Tradescantieae is in question, due to the position of Palisota as sister to all other Tradescantieae plus Commelineae. The phylogeny supports the most recent classi®cation of the family with monophyletic tribes Tradescantieae (minus Palisota) and Commelineae, but is highly incongruent with a morphology-based phylogeny. This incongruence is attributed to convergent evolution of morphological characters associated with pollination strategies, especially those of the androecium and in¯orescence. Analysis of the combined data sets produced a phylogeny similar to the rbcL phylogeny. The combined analysis differed from the molecular one, however, in supporting the monophyly of Dichorisandrinae. The family appears to have arisen in the Old World, with one or possibly two movements to the New World in the Tradescantieae, and two (or possibly one) subsequent movements back to the Old World; the latter are required to account for the Old World distribution of Coleotrypinae and Cyanotinae, which are nested within a New World clade.
