Severe Disturbance

The present-day vegetation of a cemetery at Gingin, Western Australia, is described by means of normal and inverse information analysis. In spite of severe disturbance during the past 10 years through annual burning and slashing, a well-defined floristic pattern is identifiable, even in the absence from the analysis of the two most characteristic species, Anigozanthos manglesii and A. humilis. It is suggested that whereas, in the past, parts of the cemetery were ecologically distinct and characterized by different groups of species, regular disturbance is altering these ecological conditions and causing changes in the distribution and behaviour of the species present. This changing ecology appears to be most sensitively demonstrated by the behaviour of A. manglesii and A. humilis.

Over the past 30 years in Western Australia (WA), there has been heated debate about the future use of the remaining karri and jarrah forests in the south-west of the State. This debate revolves around policy proposals from two social movements: one wants to preserve as much of the remaining old-growth forests as possible, and an opposing movement supports a continued

Over the past decade much progress has been made in an effort to determine which fungi are mycorrhizal symbionts. It is now apparent that one ectomycorrhizal or ectendomycorrhizal host is often able to form mycorrhizae with a wide variety of higher fungi. Evidence is presented which supports the hypothesis that fungal succession occurs as the host matures. In addition, fungi which are normally ectomycorrhizal may sometimes form endomycorrhizae on different hosts or under altered ecological conditions. There has also been much evolution in fruiting-body form and mode of spore discharge especially under severe montane or desert conditions. As a result patterns are emerging in the Homobasidiomycetes at the order, family, and generic level in the evolution of the mycorrhizal habit. Spore morphology, habitat, and distribution are listed and discussed in relation to the biological role of the fungi.

Mrsa Strains

Methicillin-resistant Staphylococcus aureus (MRSA) is one of the most complicated problems in infection control and disease prevention. Imported strains or group of similar strains called clones were introduced from other states within Australia and also from other countries. Western Australia (WA) MRSA clones known to be the most predominant clones circulating in Western Australia (WA). However, MRSA strains originally from other states and countries outside Australia (imported) have increased in number in the last decades. The aim of this study was to examine the epidemiology of CA MRSA clones in Western Australia for the past 11 year’s period (2003-2013). There were 10 predominant clones of CA-MRSA circulating in WA with WA MRSA-1 (32,82%), Queensland (22,67 %) and WA MRSA-2 (22,67 %) clones as the top three predominant clones. The percentage of PVL positive CA-MRSA clones such as Queensland (Qld) clone has been increasing significantly (R2=0,67) from 2,38 % in 2002 to 25,69% in 2013. In contrast, the percentages of two major PVL negative clones, WA MRSA-1 and WA MRSA 2, have been decreasing nearly by half from 52,38 % to 27,71 % and 30,95 % to 16,59 % respectively in the last 11 years. PVL positive clones have been introduced in WA from other states and overseas in the last eleven years. Due to the virulence factor of PVL toxin, the emergence of PVL positive CA-MRSA should be considered as public health concerns.

AbstractThe State Child Development Centre (SCDC) of Western Australia has been involved in the assessment and management of children with attention deficit hyperactivity disorders over the past twenty years. It is a Centre committed to the multimodal interdisciplinary approach to this and related developmental problems. Incorporated in this approach is the recognition that medication is likely to be an essential component in order to facilitate other measures being effective for a majority of children with well established attentional disorders. However, the Centre recognises that the concept of ADHD is not adequate to explain all the developmental problems of children, An alternative conceptualisation of ADHD as multiple stimuli disorganisation syndrome (MSDS) is proposed.

Three separate surveys were carried out in commercial lupin crops in the major lupin growing region of Western Australia in 1986, 1990, and 2004–05. In total, 333 sites were sampled and plants assessed for the incidence and cause of root and hypocotyl rots. Measurements were made of plant density and sowing depth at all sites. In all surveys, root rot was more common than hypocotyl rot. Root rot occurred in more than 95% of sites in each survey; however, a greater proportion of sites had high levels of root rot in early surveys. The incidence of root rot within sites decreased from an average of 34.9% in 1986 to 10.2% in 2004–05. Hypocotyl rot incidence varied among surveys, incidence of infected paddocks, and within-paddock incidence was greatest in the 1990 survey. Hypocotyl rot incidence was lowest in the 2004–05 survey. Rhizoctonia solani and Pleiochaeta setosa were commonly isolated from root lesions and R. solani was the predominant pathogen isolated from hypocotyl lesions. Analysis of the R. solani isolates by pectic zymogram showed that the ZG3 strain was most regularly isolated from roots and hypocotyls. This series of surveys indicates that the incidence of root rots in commercial lupin paddocks in Western Australia has decreased dramatically over the past 20 years; however, root rot still occurs in most paddocks regardless of soil type, location, crop rotation, and management systems.

The Noongar Aboriginal people are the traditional owners of the southwest of Western Australia, including the land on which the city of Perth is located. Their recent history has been dominated by brutal and racist government policies that have created a diverse and complex community working to rediscover and preserve Noongar culture. Community media can be an effective and empowering tool for preserving culture, shaping a contemporary Noongar identity and creating a dialogue between the Indigenous and non-Indigenous urban community of Perth. This article discusses issues of Noongar identity in Perth, and looks at how lessons from the past are shaping new Noongar media initiatives and the establishment of Noongar radio.

The black-footed rock-wallaby (Petrogale lateralis) was once widespread and abundant in rock-piles and ranges in the Warburton region of Western Australia. However, by the 1970s a major decline in its distribution and abundance was apparent. Ranges and rock outcrops were searched with local Aboriginal people to document the past and present distribution and abundance of the species and Aboriginal knowledge of its ecology. The journals of explorers, prospectors and surveyors were examined for records of rock-wallabies. Geologists, dingo trappers and other people who had worked in the region since 1930 were interviewed to document more recent sightings. Extant, small populations of rock-wallabies were located in six ranges, where they were inhabiting extensive gabbro rock-piles and rugged quartzite gullies, often in close proximity to permanent water. None of the granite outcrops visited had extant populations. Continuing local extinctions suggest that surviving populations are under threat and management intervention is required for their long term conservation.

Colour Morphs

In the wild, Coni/urus penicillatus has two tail colour morphs, one entirely black and the other with a white distal brush of variable length. These colour morphs have been used in the past for taxonomic purposes. A small proportion (4'6%) of laboratory-reared animals have a white interstitial section. Pedigree data were collected from a laboratory colony (n = 173) established using seven wild-caught animals from the north Kimberley region, Western Australia. The hypothesis tested was that black tail is inherited as a Mendelian character recessive to white tip. Matings between black-tailed individuals always gave black offspring. Crosses between other colour morphs also supported this hypothesis.

The article, based on the statistical information analysis, describes the water economy of Karelia (water consumption and water disposal), their current state and dynamics for the period from 1970 to 2015 in conjunction with the socio-economic conditions of the Republic development. The volumes of water use for different water consumers (industry, household, fishery and agriculture) are estimated and the specifics of their variations are found. It is shown that the industry continues to be the main water consumer in the region. We have established that the share of household consumption in the overall structure of water consumption has been constantly increasing over the past 30 years, and agricultural water consumption has been continuously decreasing and tending to zero. We specified annual increase in the use of water for fisheries (store-pond trout farming). Some problems of quantitative accounting of water resources use and generalization of primary information have been discussed.

The tolerance of the three species of Bettongia to fluoroacetate has been determined. B. gaimardi is comparable with most species of herbivorous mammals, B. lesueur is highly tolerant and B. penicillata has an exceptionally high tolerance. These differences reflect the past distribution of these species in relation to plants containing fluoroacetate. The relevance of these tolerance levels in the management of Bettongia populations (by the control of introduced predators) is discussed. A more general role for 1080 in the conservation of threatened fauna in Western Australia is suggested.
