Group Species

Amongst Australian non-baitable Dvosophila species, the inornata group of the subgenus Scaptodrosophila dominates in southern Australia. Distribution patterns correspond to the temperate zone flora so that, with one exception, the northerly limit of the group occurs in the southern Queensland upland forests. Amongst non-baitables only inornata-group species occur in south-west Western Australia and South Australia, while the species-group dominates in Victoria and Tasmania. In eastern Victoria and New South Wales other Scaptodrosophila species occur in increasing numbers towards the north, although the inornata group remains dominant. Two species occur exclusively in south-west Western Australia, while one desiccation-resistant species is common on both sides of the Nullabor. Distribution and speciation patterns are discussed in relation to past climates.

Historical Accounts

The numbat (Myrmecobius fasciatus ) was formerly widespread across most of southern Western Australia, South Australia and western New South Wales. It delined in the early 1900's, possibly due to foxes, cats, or an epizootic. Protection through control of foxes and cats, and translocation, has resulted in several populations being re-established at sites of historical distribution.

The genus Amperea Adr. Juss. contains eight species, six of which are confined to the south-west of Western Australia. The seventh occurs only in central Australia while the eighth ranges from central Queensland to Tasmania and extends to the south-east of South Australia. A. simulans, from Western Australia, is described as new, and A. xiphoclada var. papillata and A. xiphoclada var. pedicellata from New South Wales are recognised as new varieties; A. xiphoclada var. pedicellata is probably now extinct. Lectotypes are chosen for A. micrantha and A. volubilis. All species are described in detail and a key to identify them is provided. The diagnostic relevance of a range of attributes of the genus is reviewed as is its classificatory history.* The first of a projected series of revisions of genera traditionally included in Stenolobeae Benth., and others related to them, which are intended to form the basis of future Flora of Australia accounts.

Constitutional systems of Westminster heritage are increasingly moving towards fixed-term parliaments to, amongst other things, prevent the Premier or Prime Minister opportunistically calling a ‘snap election’. Amongst the Australian states, qualified fixed-term parliaments currently exist in New South Wales, South Australia and Victoria. Queensland, Tasmania and Western Australia have also deliberated over whether to establish similar fixed-term parliaments. However, manner and form provisions in those states' constitutions entrench the Parliament's duration, Governor's Office and dissolution power. In Western Australia and Queensland, unlike Tasmania, such provisions are doubly entrenched. This article considers whether these entrenching provisions present legal obstacles to constitutional amendments establishing fixed-term parliaments in those two states. This involves examining whether laws fixing parliamentary terms fall within section 6 of the Australia Acts 1986 (Cth) & (UK). The article concludes by examining recent amendments to the Electoral Act 1907 (WA) designed to enable fixed election dates in Western Australia without requiring a successful referendum.

Molecular systematics, morphological analysis, and hybrid crossing identify a third taxon, Aedes (Halaedes) wardangensis sp.nov., of the Aedes (Halaedes) australis species-group (Diptera: Culicidae)

Phylogenetic and morphological analyses, male morphology, and hybrid crossing indicate that a population from Wardang Island, South Australia, is distinct from the monophyletic series of populations of Aedes (Halaedes) australis (Erichson) 1842 from Victoria, Tasmania, New South Wales, and New Zealand. The name Aedes (Halaedes) wardangensis has been assigned to the new species. Phylogenetic analysis of DNA sequences from the cytochrome oxidase II and internal transcribed spacer loci support the resurrection of Aedes (Halaedes) ashworthi Edwards, 1921 (Brust and Mahon, 1997). Aedes ashworthi is known only from Western Australia and was found to be infertile when crossed with Ae. wardangensis from South Australia and Ae. australis from New Zealand. The hybrid of Ae. australis from New South Wales × Ae. australis from New Zealand was fertile for three generations, documenting these as conspecific.

Differential Cultivars

In 1995–96, a survey of soil samples from subterranean clover (Trifolium subterraneum L.) paddocks was conducted across Victoria, South Australia, New South Wales and Western Australia, to determine the distribution and the prevalence of races of Phytophthora clandestina (as determined by the development of root rot on differential cultivars), and the association of its occurrence with paddock variables. In all states, there was a weak but significant association between P. clandestina detected in soil samples and subsequent root rot susceptibility of differential cultivars grown in these soil samples. Phytophthora clandestina was found in 38% of the sampled sites, with a significantly lower prevalence in South Australia (27%). There were significant positive associations between P. clandestina detection and increased soil salinity (Western Australia), early growth stages of subterranean clover (Victoria), mature subterranean clover (South Australia), recently sown subterranean clover (South Australia), paddocks with higher subterranean clover content (Victoria), where herbicides were not applied (South Australia), irrigation (New South Wales and Victoria), cattle grazing (South Australia and Victoria), early sampling dates (Victoria and New South Wales), sampling shortly after the autumn break or first irrigation (Victoria), shorter soil storage time (Victoria) and farmer’s perception of root rot being present (Victoria and New South Wales). Only 29% of P. clandestina isolates could be classified under the 5 known races. Some of the unknown races were virulent on cv. Seaton Park LF (most resistant) and others were avirulent on cv. Woogenellup (most susceptible). Race 1 was significantly less prevalent in South Australia than Victoria and race 0 was significantly less prevalent in New South Wales than in South Australia and Western Australia. This study revealed extremely wide variation in the virulence of P. clandestina. The potential importance of the results on programs to breed for resistance to root rot are discussed. in South Australia.
