Nine communities are defined based on classification (Kulczynski association). These Nine communities were mapped based on ground truthing, air photo interpretation and landform. Much of the reserve is characterised by Eucalyptus crebra, Callitris glaucophylla, Cadellia pentastylis, Acacia cheelii and Callitris endlicheri with and understorey shrub layer of Beyeria viscosa, Notelaea microcarpa, Melichrus urceolatus and Solanum parvifolium with a ground layer of Austrostipa scabra, Aristida ramosa, Cheilanthes sieberi, Cheilanthes distans, Cymbopogon refractus Microlaena stipoides and Cyperus gracilis. The communities described and their status are: Floristic Community Area Reservation Status C1: Eucalyptus crebra – Well reserved and not of conservation concern 828 Callitris glaucophylla C2: Eucalyptus viridis – Highly disjunct and restricted assemblage should 44 Geijera parviflora be considered of concern. C3: Cadellia pentastylis 44 Listed as endangered on the TSC Act. C4: Callitris glaucophylla Highly disjunct and small occurrences but not of 26 conservation concern at present C5: Callitris glaucophylla – Well reserved and not of conservation concern Eucalyptus crebra – Acacia 824 cheelii C6: Acacia triptera – Kunzea Highly restricted and disjunct, not of current 15 sp. D concern. C7: Eucalyptus crebra – Well reserved and not of conservation concern. 300 Callitris endlicheri C8: Callitris endlicheri 5 Not of conservation concern. C9: Casuarina Not of conservation concern at present. cunninghamiana – 13 Melaleuca bracteata A total of 287 vascular plant taxa were found from 186 families and 66 genera. Four species; Cadellia pentastylis (TSC Vulnerable), Leionema viridiflora (3RCa), Pomaderris queenslandica (TSC Endangered) and Tylophora linearis (TSC & EPBC Endangered). Dr John T.

  • Reconstructing the Basal Angiosperm Phylogeny: Evaluating Information Content of Mitochondrial Genes
    55 (4) • November 2006: 837–856 Qiu & al. • Basal angiosperm phylogeny Reconstructing the basal angiosperm phylogeny: evaluating information content of mitochondrial genes Yin-Long Qiu1, Libo Li, Tory A. Hendry, Ruiqi Li, David W. Taylor, Michael J. Issa, Alexander J. Ronen, Mona L. Vekaria & Adam M. White 1Department of Ecology & Evolutionary Biology, The University Herbarium, University of Michigan, Ann Arbor, Michigan 48109-1048, U.S.A. [email protected] (author for correspondence). Three mitochondrial (atp1, matR, nad5), four chloroplast (atpB, matK, rbcL, rpoC2), and one nuclear (18S) genes from 162 seed plants, representing all major lineages of gymnosperms and angiosperms, were analyzed together in a supermatrix or in various partitions using likelihood and parsimony methods. The results show that Amborella + Nymphaeales together constitute the first diverging lineage of angiosperms, and that the topology of Amborella alone being sister to all other angiosperms likely represents a local long branch attrac- tion artifact. The monophyly of magnoliids, as well as sister relationships between Magnoliales and Laurales, and between Canellales and Piperales, are all strongly supported. The sister relationship to eudicots of Ceratophyllum is not strongly supported by this study; instead a placement of the genus with Chloranthaceae receives moderate support in the mitochondrial gene analyses. Relationships among magnoliids, monocots, and eudicots remain unresolved. Direct comparisons of analytic results from several data partitions with or without RNA editing sites show that in multigene analyses, RNA editing has no effect on well supported rela- tionships, but minor effect on weakly supported ones. Finally, comparisons of results from separate analyses of mitochondrial and chloroplast genes demonstrate that mitochondrial genes, with overall slower rates of sub- stitution than chloroplast genes, are informative phylogenetic markers, and are particularly suitable for resolv- ing deep relationships.

  • 'Soils' and 'Vegetation'?
    Is there a close association between ‘soils’ and ‘vegetation’? A case study from central western New South Wales M.O. Rankin1, 3, W.S Semple2, B.W. Murphy1 and T.B. Koen1 1 Department of Natural Resources, PO Box 445, Cowra, NSW 2794, AUSTRALIA 2 Department of Natural Resources, PO Box 53, Orange, NSW 2800, AUSTRALIA 3 Corresponding author, email: [email protected] Abstract: The assumption that ‘soils’ and ‘vegetation’ are closely associated was tested by describing soils and vegetation along a Travelling Stock Reserve west of Grenfell, New South Wales (lat 33° 55’S, long 147° 45’E). The transect was selected on the basis of (a) minimising the effects of non-soil factors (human interference, climate and relief) on vegetation and (b) the presence of various soil and vegetation types as indicated by previous mapping. ‘Soils’ were considered at three levels: soil landscapes (a broad mapping unit widely used in central western NSW), soil types (according to a range of classifications) and soil properties (depth, pH, etc.). ‘Vegetation’ was considered in three ways: vegetation type (in various classifications), density/floristic indices (density of woody species, abundance of native species, etc.) and presence/absence of individual species. Sites along the transect were grouped according to soil landscapes or soil types and compared to vegetation types or indices recorded at the sites. Various measures indicated low associations between vegetation types and soil landscapes or soil types. Except for infrequent occurrences of a soil type or landscape, any one soil type or landscape was commonly associated with a number of vegetation types and any one vegetation type was associated with a number of soil landscapes or soil types.

Frances Johnston August 2005 FORWARD “In a small section of the garden a tiny weed spoke to the blooms that grew there. ‘Why,’ he asked, ‘does the gardener seek to kill me? Do I not have a right to life? Are my leaves not green, as yours are? Is it too much to ask that I be allowed to grow and see the sun?’ The blooms pondered on this, and decided to ask the gardener to spare the weed. He did so. Day by day the weed grew, stronger and stronger, taller and taller, its leaves covering the other plants, its roots spreading.
