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.

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

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.

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.

Attention Deficit Hyperactivity Disorders

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.

Growing Region

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.

Fit For Purpose

Abstract Telephone surveys have become much maligned in the past few years, considering recent failures to correctly predict elections worldwide, response rates declining into the single digits, and the rise of low-cost, nonprobabilistic alternatives. Yet there is no study assessing the degree to which data attained via modern-day telephone interviewing has or has not significantly declined in terms of data quality. Utilizing an elemental approach, we evaluate the bias of various cross-tabulations of core demographics from a collection of surveys collected over the past two decades. Results indicate that (1) there has been a modest increase in bias over the past two decades but a downward trend in the past five years; (2) the share of cell phone interviews in samples has a significant impact on the bias; (3) traditional weighting largely mitigates the linear trend in bias; and (4), once weighted, telephone samples are nearly on par in data quality to higher response rate unweighted in-person data. Implications for the “fit for purpose” of telephone data and its general role in the future of survey research are discussed given our findings.

Little is known of the area of occupancy, extent of occurrence, abundance, density or habitat use of the greater bilby (Macrotis lagotis) in the north of Western Australia. To seek broad collaborative agreement on a research agenda, the Western Australian Department of Parks and Wildlife hosted a workshop where research priorities were identified through a facilitated process. Five key areas for future research effort were identified: (1) refine survey methods, (2) improve understanding of habitat use, (3) improve understanding of the genetic structure of (meta)populations, (4) improve understanding of the threat posed by introduced predators and herbivores, and (5) improve understanding of how fire regimes affect bilby conservation. A conceptual model describing the main landscape components thought to be influencing distribution is used to reconcile existing knowledge, link research priorities for the bilby in the north of Western Australia, and guide the development of an integrated program of research. The broad nature of the priorities reflects the limited knowledge of bilbies in the north of the state; however, this research program provides an opportunity to increase knowledge to enact both species- and ecosystem-focused approaches to conservation, and potentially contributes towards the implementation of more dynamic conservation approaches for mobile species.

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.
