Land Unit Master Land Unit Information Sheet Land system name: Desert Land unit: DT1 General description This land unit represents one of the most common, and most extensive, soil-vegetation associations on the Desert Uplands plateau. The very deep, sandy gradational and texture-contrast soils are part of an extensive sandsheet, easily recognised by the bright red colour of the soils and the specific vegetation community. The mid-tall woodlands of Eucalyptus similis (Queensland yellowjacket), Corymbia clarksoniana (Clarkson's bloodwood), C. leichhardtii (rustyjacket) and C. setosa (applejack) often form a "grove-like" pattern across the slope with broad open areas of Triodia species (spinifex) in between each row. A dense understorey dominated by Acacia meleodora (waxy wattle), A. coriacea (desert oak), Alphitonia excelsa (soap tree) and Petalostigma pubescens (quinine tree) benefit from the leaf litter under the tree canopy and the extra soil moisture obtained by "capturing" water runoff from the adjacent spinifex area upslope. Regional ecosystem 10.5.1 is predominant.

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.

  • Jewel Bugs of Australia (Insecta, Heteroptera, Scutelleridae)1
    © Biologiezentrum Linz/Austria; download unter www.biologiezentrum.at Jewel Bugs of Australia (Insecta, Heteroptera, Scutelleridae)1 G. CASSIS & L. VANAGS Abstract: The Australian genera of the Scutelleridae are redescribed, with a species exemplar of the ma- le genitalia of each genus illustrated. Scanning electron micrographs are also provided for key non-ge- nitalic characters. The Australian jewel bug fauna comprises 13 genera and 25 species. Heissiphara is described as a new genus, for a single species, H. minuta nov.sp., from Western Australia. Calliscyta is restored as a valid genus, and removed from synonymy with Choerocoris. All the Australian species of Scutelleridae are described, and an identification key is given. Two new species of Choerocoris are des- cribed from eastern Australia: C. grossi nov.sp. and C. lattini nov.sp. Lampromicra aerea (DISTANT) is res- tored as a valid species, and removed from synonymy with L. senator (FABRICIUS). Calliphara nobilis (LIN- NAEUS) is recorded from Australia for the first time. Calliphara billardierii (FABRICIUS) and C. praslinia praslinia BREDDIN are removed from the Australian biota. The identity of Sphaerocoris subnotatus WAL- KER is unknown and is incertae sedis. A description is also given for the Neotropical species, Agonoso- ma trilineatum (FABRICIUS); a biological control agent recently introduced into Australia to control the pasture weed Bellyache Bush (Jatropha gossypifolia, Euphorbiaceae). Coleotichus borealis DISTANT and C. (Epicoleotichus) schultzei TAUEBER are synonymised with C. excellens (WALKER). Callidea erythrina WAL- KER is synonymized with Lampromicra senator. Lectotype designations are given for the following taxa: Coleotichus testaceus WALKER, Coleotichus excellens, Sphaerocoris circuliferus (WALKER), Callidea aureocinc- ta WALKER, Callidea collaris WALKER and Callidea curtula WALKER.

  • Assemblage Patterns and Environmental Gradients in The
    Chapter 5. Effects of grazing and fire on fauna and flora in Eucalyptus similis tropical savanna woodland. “At length, tracing the dry bed of a creek, (Warrigal Creek, from the many Warrigals or dingoes), he crested the forest-clad Main Dividing Range. A curious sight appeared - trees plastered with yellow earth: these trees, called yellowjacks, are soft wood, so white ants enclose them with earth walls and eat the wood out, leaving shells which first strong wind or bush-fire sweeps away. Around these grew gaudy poison-bush.” (p. 49. Bennett 1928). Introduction There is little argument that fire has profoundly influenced the historical evolution and current patterns of biota on the Australian continent. This is clear from the predominance of fire-dependent and promoting flora (Kershaw et al. 2002). Other indications of the importance of fire include systems of biota inexorably linked to fire age (Williams and Gill 1995), and climatic patterns that result in fierce seasonal electrical storms sparking wildfire (Cook and Heerdegen 2001). There is also strong evidence of a long history of prescribed burning by Aboriginal land managers (Hallam 1985; Crowley and Garnett 2000). However with European settlement, there was a rapid cessation of pre-existing regimes (Bowman 2000; Yibarbuk et al. 2001) and a shift to regimes dictated by pastoral land use and human property protection (Crowley and Garnett 2000). There has been vigorous debate on the extent and importance of traditional Aboriginal burning (e.g. Flannery 1994; Benson and Redpath 1997), though there is general acceptance of an impact on biodiversity (Bolton and Latz 1978; Burbidge and McKenzie 1989; Franklin 1999).

  • Temporal and Spatial Patterns in Drought-Related Tree Dieback In
    Journal of Applied Ecology Temporal and spatial patterns in drought-related tree 1999, 36, dieback in Australian savanna 1035±1050 R.J. FENSHAM and J.E. HOLMAN Queensland Herbarium, Brisbane Botanic Gardens, Mt Coot-tha Road, Toowong Qld 4066, Australia Summary 1. Determining the relative importance of anthropogenic and non-anthropogenic in¯uences on structure is essential for informed management of savannas and for carbon accounting under greenhouse obligations. 2. The magnitude of drought and dieback was examined using the rainfall records for Queensland and historical records of dieback. Tree dieback was examined in Eucalyptus savanna in north Queensland by random sampling after a recent drought. 3. Analysis of rainfall records revealed that particularly severe droughts occurred three times this century in inland Queensland, while more local droughts of similar intensity had been less frequent elsewhere. A review of historical records con®rmed extensive tree death following past droughts. 4. Approximately 29% of trees were dead or nearly dead over a sampled area of about 55 000 square kilometres. Dieback was greatest on alkaline igneous rocks, intermediate on metamorphics, sedimentary rocks and acid igneous rocks, and low- est on alluvia. 5. Of the widespread dominants, the Eucalyptus crebra±E. xanthoclada species complex was highly susceptible to dieback, E. brownii and E. melanophloia±E. whitei moderately aected, and Corymbia clarksoniana and Melaleuca nervosa less severely aected. Preferential death of large over small size classes was signi®cant for only E. crebra±E. xanthoclada. 6. The 1990s drought was especially intense in the vicinity of the North Queensland study area. However, within the study area there were only weak cor- relations between dieback and rainfall de®cits as derived from modelled data.

    Land Unit Information Sheet Land system name: Wattlevale Land unit: WE4 General description This land unit is confined to the steep slopes dropping into Bullock creek, which has incised the western margin of the Wattlevale land system. Sites with detailed soil and vegetation information are not available, however, general observations during field work have been collated to give some useful information. The dominant vegetation is a mid-high forest of Acacia shirleyi (lancewood) with a ground cover of Triodia pungens (gummy spinifex) and Themeda triandra (kangaroo grass). It is not unusual to find an occasional Eucalyptus similis (yellowjacket) or Corymbia leichhardtii (rustyjacket) on pockets of deep red sands, which are remnants of the huge sandsheet to the east (Wishaw (WW) land system) and south east (Desert (DT) land system). Regional ecosystem 10.7.3 is predominant.
