Rural pharmacist and consumer perspectives of expanded pharmacy services to address inequity in accessing health services.

Australians living in rural and remote communities have inadequate access to health services, contributing to poorer health outcomes compared to their metropolitan counterparts. This study investigated consumers' and pharmacists' perspectives of expanded pharmacy services in rural and remote communities in Australia. It aims to identify the role of the pharmacist in addressing the inequity of access to healthcare through the provision of expanded services in rural and remote practice. A concurrent parallel mixed-methods study was undertaken in rural Western Queensland, Australia to include a survey of 167 consumers and in-depth interviews with 10 pharmacists. Quantitative data analysis employed descriptive statistics and chi-square tests, while qualitative data were analysed thematically against the constructs of the Diffusion of Innovations Theory. Consumers indicated that they would like to access weight management services (53%), whereas pharmacists thought it was important to offer respiratory clinics and services. Both pharmacists and consumers would like to see diabetes checks (30% and 56%, respectively) and vision, hearing, and ear checks (40% and 53%, respectively) implemented as services in community pharmacies. Most consumers (97%) believe pharmacists have the skills and knowledge to deliver expanded services and in doing so, they would improve the overall health of the community. Pharmacists reported staffing availability, workload and time constraints, cost, and jeopardizing inter-professional relationships as barriers to implementing expanded services. Consumers were supportive of pharmacists working to their full scope of practice to provide expanded services, whereas pharmacists, while open to the idea, highlighted that there were barriers to overcome.

Life cycle, host specificity and potential impact of a gall-inducing thrips Acaciothrips ebneri, a biological control agent for prickly acacia (Vachellia nilotica subsp. indica) in Australia

Prickly acacia (Vachellia nilotica subsp. indica (Benth.) Kyal. & Boatwr.; Fabales: Fabaceae) is a Weed of National Significance and a target for biological control in Australia. Currently there are no effective biological control agents for the weed in Australia. Based on genetic and climate matching, a gall thrips (Acaciothrips ebneri Karny; Thysanoptera: Phlaeothripidae) inducing rosette galls resulting in shoot tip dieback, was identified as a prospective biological control agent from Ethiopia. No-choice host-specificity tests were conducted on 59 test plant species in a high security quarantine in Brisbane, Australia. Acaciothrips ebneri is host-specific, inducing galls and reproducing only on prickly acacia. Acaciothrips ebneri, as predicted by the CLIMEX model, is suited to hot and arid western Queensland where major prickly acacia infestations occur. The Australian Government approved A. ebneri for field release in October 2022. This is the first time a true gall-inducing thrips has ever been approved as a weed biological control agent. Field releases commenced in January 2023 and are in progress. There are early signs of field establishment resulting in shoot tip die back in the field, and field release and monitoring will continue.

Density of a cryptic Australian small mammal: The threatened Julia Creek dunnart (Sminthopsis douglasi).

Globally, hundreds of mammal species face the threat of extinction in the coming decades, and in many cases, their ecology remains poorly understood. Fundamental ecological knowledge is crucial for effective conservation management of these species, but it is particularly lacking for small, cryptic mammals. The Julia Creek dunnart (Sminthopsis douglasi), a threatened, cryptic carnivorous marsupial that occurs in scattered populations in the central west of Queensland, Australia, was once so poorly studied that it was believed extinct. Sporadic research since its rediscovery in the early 1990s has revealed that S. douglasi is distributed across land at risk from many threats. Fundamental knowledge of S. douglasi population density is urgently required to inform conservation management at key sites, yet the species has historically proven hard to detect. Indeed, the status of the largest known population of S. douglasi, in Bladensburg National Park, is unknown. Here, we conducted a population study on S. douglasi at two sites within Bladensburg National Park via live mark-recapture surveys during 2022 and 2023. From likelihood-based spatially explicit capture-recapture (SECR) modelling we provide the first estimates of density and population size for S. douglasi. Live trapping resulted in captures of 49 individual S. douglasi (with 83 captures total, including recaptures). We estimated S. douglasi to occur at a density of 0.38 individuals ha-1 (0.25-0.58) at one site and 0.16 individuals ha-1 (0.09-0.27) at another site, with an estimated mean population size in suitable habitat at Bladensburg National Park of 1211 individuals (776-1646). Our S. douglasi density estimates were similar to that reported for other threatened small mammals in Australia. We also found evidence of extreme S. douglasi population fluctuations over time at Bladensburg National Park, which is of concern for its future conservation. Our study has provided the first estimate of density for S. douglasi, a threatened dasyurid species from the Mitchell Grass Downs of central western Queensland, Australia. Our research provides crucial population data to assist the management of this poorly studied species. We demonstrate a method that can be applied to species with low detection probability to ultimately help address the mammal extinction crisis faced by Australia and the rest of the world.

Factors associated with unintended pregnancy and contraceptive practices in justice-involved adolescent girls in Australia.

Despite a decline in unintended teenage pregnancy in Australia, rates remain higher amongst justice-involved adolescent girls, who are more likely to be from disadvantaged socio-economic backgrounds, have histories of abuse, substance use and/or mental health issues. Furthermore, exposure to the criminal justice system may alter access to education and employment and opportunities, potentially resulting in distinct risk-factor profiles. We examine factors associated with unintended pregnancy, non-contraceptive use and Long-Acting Reversible Contraception (LARC) in a sample of sexually active, justice-involved adolescent girls from Western Australia and Queensland. Data from the Mental Health, Sexual Health and Reproductive Health of Young People in Contact with the Criminal Justice System (MeH-JOSH) Study was analysed on 118 sexually active adolescent girls. Participants were aged between 14 and 17 years, purposefully sampled based on justice-system involvement and completed an anonymous telephone survey. We constructed two multivariate models taking reproductive outcomes as the dependent variables. Over one quarter (26%, 30/118) reported a past unintended pregnancy, 54 did not use any contraception at their last sexual encounter, and 17 reported LARC use. Following adjustments in the multivariate analysis, lifetime ecstasy use was associated with both unintended pregnancy (aOR 3.795, p = 0.022) and non-contraception use (aOR 4.562, p = 0.004). A history of physical abuse was also associated with both any contraception (aOR 3.024, p = 0.041) and LARC use (aOR 4.892, p = 0.050). Identifying as Aboriginal & Torres Strait Islander, education/employment status and geographic location appeared to have no association. Our findings suggest that justice-involved adolescent girls have distinct risk factors associated with unplanned pregnancy and contraception use compared to the general population, but more research is required to understand the mechanisms and contexts underlying these risk factors. How exposure to physical violence may encourage contraception and LARC use, in particular, warrants further attention as does the association with ecstasy use.

Crustal architecture and tectonic development of western Queensland, Australia, based on deep seismic reflection profiling: Implications for Proterozoic continental assembly and dispersal

Interpretation of 2014–2015 deep crustal seismic reflection and magnetotelluric data has revised the architecture and geodynamic framework of western Queensland, with implications for the assembly and dispersal of the supercontinents Nuna, Rodinia and Gondwana. In the Mount Isa Province, crustal-scale boundaries of the Leichhardt River Domain, Kalkadoon-Leichhardt Domain and Eastern Subprovince are mapped in the third dimension. The Leichhardt River and Kalkadoon-Leichhardt domains have similar Nd isotopic T2DM model ages to provinces to the west, indicating they were part of ancestral North Australian Craton (NAC); the Eastern Subprovince is a separate terrane, with the Pilgrim Fault a collisional suture. The Gidyea Suture Zone separates the Mount Isa Province from the subsurface Numil Seismic Province. To the east, the west-dipping Yappar Fault separates east-dipping structures in the west from west-dipping structures in the east, forming a classic doubly vergent orogen within the upper plate of a convergent margin. The northwestern boundary of the Bernfels Seismic Province, the Kynuna Fault, truncates the Gidyea Suture Zone, implying this seismic province was welded to the NAC prior to initial deposition of the Etheridge Province. The Cork Fault truncates the north-south grain of the Mount Isa Province; the easternmost part of the NAC has been excised, presumably during breakup of Nuna. The subsurface Brighton Downs Seismic Province, formerly part of the northern Thomson Orogen, is a discrete seismic province, located between the NAC and the Thomson Orogen, and welded to the NAC during the accretion of Rodinia. Basement to the Thomson Orogen is a collage of microplates, accreted to the Brighton Downs Seismic Province during the assembly of Gondwana. By 530 Ma, eastern Australia faced an open Pacific Ocean, with the Thomson Orogen in a backarc setting. Thus, northeastern Australia contains a record of repeated continental accretion and breakup over at least three supercontinent cycles.

A Nineteenth Century Rural Crime in Western Queensland?

In August 1895, Andrew Barton “Banjo” Paterson was visiting his fiancée at Dagworth Station near Winton in western Queensland, Australia, when he was moved to write a bush ballad that became more prominent than even he might have expected. The question arises as to what was or were the circumstances or events that stimulated the creative mind of Paterson to write such a spirited ballad. A rural crime was certainly committed down by the billabong in the ballad, but there were real events playing out throughout the western sheep grazing country of Queensland at that time and had been for some years. This research note argues that, in identifying crimes, we can observe a dichotomy of opposites with some boundaries being contained, while others are large and fluid. Each have a particular fragility as well as a strength. Contained boundaries have a placement that has strength, but vulnerability to encroachment by powerful forces: the need to protect is ever present. It is also argued that this ballad, which contextualises a rural crime, serves as an allegory symbolising a sense of injustice, of resistance against injustice and excessive use of power.

The Importance of Context in a Global World

Global education is often framed in terms of standardised testing that makes comparisons across nations. This is particularly evident with international measures like the Programme for International Student Assessment (PISA), which tests 15-year-olds in member countries. Images on the PISA website provide representations of education that seem to clash with some of the contexts where we have conducted research. This prompted an investigation into educators’ talk about local contextual realities, and how—or whether—they were impacted by global calls for quality education. The study focused on three different educational programs: education for adolescent girls in a refugee camp in the Kurdistan Region of Iraq, school education in a western Queensland rural/remote town in Australia, and the Migrant Education Program in rural Illinois in the United States. The data were collected through semi-structured interviews and field observations. Following data analysis, three case study narratives were constructed. A final step of analysis identified four shared pillars that made learning in rural and remote areas impactful and effective: context relevance, educators’ openness to learning, flexibility of teaching/learning approaches, and responsiveness to learners’ needs. The data demonstrated that the educators had a broader picture—national or global—in mind, but their main aim was to provide learning opportunities that were responsive, flexible and contextually appropriate to their location.

Unrecognised Ant Megadiversity in the Australian Monsoonal Tropics III: The Meranoplus ajax Forel Complex

Australia’s monsoonal (seasonal) tropics are a global centre of ant diversity, but are largely unrecognised as such because the vast majority of its species are undescribed. Here we document another case of undescribed hyper-diversity within a taxon that is formally recognised as a single, widespread species, Meranoplus ajax Forel. We recognise 50 species among 125 specimens of M. ‘ajax’ that we CO1-barcoded, integrating CO1 clustering and divergence, morphological differentiation and geographic distribution. A large proportion (44%) of these species are represented by single records, indicating that very many additional species are yet to be collected in this extremely remote and sparsely populated region. Sampling has been concentrated in the Northern Territory, where 27 of the 50 species occur. If diversity in Western Australia and Queensland were similar to that in the Northern Territory, as appears likely, then the M. ajax complex would comprise >100 species. In 2000, when Australia’s monsoonal ant fauna was estimated to contain 1500 species, Meranoplus ajax was considered to represent a single species. Our previous analyses of a range of other taxa have shown that their diversity has been similarly under-appreciated in this estimate. Our findings suggest that the total number of ant species in monsoonal Australia is several thousand, which would make the region by far the world’s richest known.

The Equity of Class Ability Grouping Practices in Australian Education: Findings from a Survey in Western Australia and Queensland

Grouping students into separate classes according to their ‘ability’ is an inequitable practice that does not, overall, improve academic outcomes. Research has continued to show that class ability grouping widens the educational gap between students from disadvantaged and privileged backgrounds. PISA data analysis suggests that class ability grouping continues to be used in Australian schools, at least in Year 10. However, no research has characterized the existing class ability grouping practices being used in secondary schools from Years 7 to 9. The findings reported in this paper add quantitative evidence to the literature, showing that students are experiencing different class ability grouping practices according to their year group, subjects, and locations. An across-state survey about class ability grouping was conducted with respondents from 143 schools providing data about the schools’ class ability grouping practices. The findings reveal variations in how class grouping practices are used by schools in Australia that have been not captured in other research: Class ability grouping was activated differently in different schools, increased as students’ year levels increased, was most prevalent in Maths and English, and was used more extensively in Western Australia than in Queensland. The findings use descriptive statistics to show that students in Australia are experiencing different grouping practices, with discussion of how some practices are more inequitable than others. This raises questions about how the varied forms of class ability grouping that are being employed are contributing to educational inequalities in Australia and how future research can address this problem.

Governance for health system collaboration: The case of the South-West Queensland Primary Care Alliance, Queensland, Australia.

Background: Internationally, as countries orientate health systems to embrace an integrated, person-centered approach it demands a fundamental shift in the way health services are funded, managed and delivered. Requisite to meeting these challenges given the involvement of multiple organisations, and therefore varying governance arrangements, is strengthening of shared governance with clear and transparent accountability mechanisms, across the health system where initiatives to better integrate care are being implemented. Governance models to achieve this have been attempted in several countries. The best fit for the Australian system is likely to be the Alliance contracting approach.
 The Alliancing concept was derived from the construction industry, where different organisations work collaboratively to ensure achievement of common goal, to complete a project successfully, on time and within budget. They help one another and, where relevant, share resources. Alliance governance is the set of rules which govern an Alliance. At their core, they are centered around governance that ensures the building of collaboration and a ‘whole of system’ approach to service planning and delivery. This is different and challenging and calls on members to focus primarily on their community rather their individual circumstances / organisations.
 Target audience: Policy makers, health system executives, funders, researchers.
 Alliance Partners: Western Queensland Primary Health Network, South West Hospital & Health Services, Health Workforce Queensland, Charleville & Western Areas Aboriginal & Torres Strait Islander Community Health, Royal Flying Doctor Service, private general practices, and CheckUP.
 What we did: Thematic analysis of a previous SW partnership project, against evidence-based health governance elements for integrated care, to distil learning for the SW Primary Care 5-year plan and conducted a rapid review to identify further evidence base for the alliance governance model in health. This evidence was incorporated into a stakeholder workshop to advise implementation.
 Results/impact: Using an evidence-based governance framework for integrated care, the South-West Primary Care Alliance was developed. An Alliance Charter, outlining the rules of engagement and commitments, has been passed. A governance framework agreed and an implementation plan adopted.
 Learning for international audience: More recent Australian reform documents identify the importance of a regional approach in bringing together all sources of health funding into one coordinated local service delivery approach. In particular, the ongoing difficulty in aligning Australia’s fragmented Commonwealth and State health systems, mean that for our health system this is the most critical reform step. This is more ambitious than co-commissioning or bilateral project-focused funding. It includes all relevant service delivery organisations making formal governance commitments to work together over time in addressing key areas of service gap or duplication.
 Next steps: Three work programs have been identified by the Alliance Leadership Team for implementation 2023-2025. The first of these, workforce, has an implementation plan set for 2023. As part of the implementation the barriers and critical success factors to implementing and sustaining this model of care will be investigated.

The Queensland Virtual Integrated Practice (VIP) partnership program pilot study: an Australian-first model of care to support rural general practice

BackgroundThere is a critical lack of medical workforce internationally, and this is particularly notable in rural and remote Australia where strategies to address workforce shortages are urgently required. This pilot study aimed to implement and evaluate a Virtual Integrated Practice (VIP) Program in the Australian rural primary care setting.MethodsThe VIP model was developed using co-creation methodology and involves an urban GP joining a rural general practice team to provide ongoing care to patients remotely via secure telehealth. The pilot study was conducted in two western Queensland general practices, commencing in October 2021 with one rural practice and extending to an additional rural practice from November 2022. Evaluation included a retrospective review of service, billing and cost data, and an online survey for patients. Ethical approval was obtained from the University of Queensland Human Research Ethics Committee (Project number: 2021/HE002434).ResultsThere were 1468 services provided through to December 2022, including general consults (n = 1197), therapeutic procedures (n = 68), mental health treatment plans (n = 68) and chronic disease management plans (n = 59). Patients were predominantly female (73.1%) and did not have their appointment at the practice (57.8%). Among 1282 occasions of service, less than 20% of consultations (n = 224) required support from staff (e.g., a nurse), and more than half were repeat patient encounters (53.0%). Survey respondents (n = 45) indicated that they were satisfied (9.3%) or highly satisfied (90.7%) with the care provided, and importantly, 95.5% of respondents reported that the service improved their access to the GP. More than 20% of respondents indicated that they would attend the Emergency Department if virtual care was not available.ConclusionsData from this pilot study has informed translation to an additional 20 vulnerable rural general practices in three further rural regions in Queensland in 2023 and evaluation is ongoing. This pilot study demonstrates the feasibility and acceptability of an innovative, digitally supported community-focussed, healthcare initiative to arrest the decline in rural general practice workforce, improve patient care access and support rural practice viability.

A revised Proterozoic tectono-stratigraphy of the South Nicholson region, Northern Territory, Australia—insights from SHRIMP U–Pb detrital zircon geochronology

New SHRIMP U–Pb detrital zircon geochronology on Mesoproterozoic and Paleoproterozoic siliciclastic rocks from the South Nicholson region, in concert with recently acquired complementary regional geophysical datasets, have enabled comprehensive revision of the regional Proterozoic tectono-stratigraphy. The identification of analogous detrital zircon spectra of units deposited in half-graben hanging walls of major east-northeast-trending extensional faults, offers compelling evidence for regional tectono-stratigraphic correlation. This study sampled units from the hanging walls of the Benmara, Bauhinia, and Maloney-Mitchiebo (east-northeast-trending) faults, which identified immature proximal lithofacies hosting a small yet persistent population of ca 1660–1640 Ma aged zircon and lack Mesoproterozoic detritus. The timing of this event is consistent with deposition coincident with crustal extension during the extensional River Event at ca 1640 Ma, an event previously identified from the Lawn Hill Platform in western Queensland. This finding suggests the hanging wall sequences are chrono-stratigraphically equivalent to the highly prospective sedimentary rocks of the Isa Superbasin, host to world-class sediment-hosted base metals deposits across western Queensland and northeastern Northern Territory. Subsequent inversion of the extensional faults resulted in development of south-verging thrusts, and exhumation of late Paleoproterozoic hanging wall siliciclastic rocks through overlying Mesoproterozoic South Nicholson Group rocks as fault propagated roll-over anticlines. These geochronology data and interpretations necessitate revision of the existing stratigraphy and the renaming of a number of stratigraphic units in the South Nicholson region. Accordingly, the distribution of the highly prospective late Paleoproterozoic units of the McArthur Basin, Lawn Hill Platform and Mount Isa Province is greatly expanded across the South Nicholson region. These findings imply that the underexplored South Nicholson region is a highly prospective greenfield area for energy and mineral resources. KEY POINTS SHRIMP U–Pb detrital zircon geochronology provides a basis for revision of the Proterozoic stratigraphy in the South Nicholson region. Correlation of sedimentary units across the region is based on closely matching zircon age spectra, lithofacies and tectono-sedimentary setting. Revision of the Proterozoic stratigraphy increases the prospectivity for sediment-hosted base metal resources across the South Nicholson region.

The distribution, chronology and significance of late Holocene aged stone-based structures on Pitta Pitta Country, western Queensland

There is considerable discourse around the timing of Australia’s interior colonisation and whether environmental or technological impacts pushed people into occupying more arid environments. However, the general scarcity of rockshelter sites and the limited amount of research undertaken to date in central western Queensland has meant this region has only been peripherally considered in such debates. It is well recognised that, by the time Europeans began documenting lifeways in the region in the late 1870s, central western Queensland had given rise to complex and thriving Aboriginal societies, despite the boom-or-bust nature of its seasonal cycles. One of these is the Pitta Pitta people, who had a pivotal role in a vast trade network that traversed the Lake Eyre Basin, extending north to the Gulf of Carpentaria. The Pitta Pitta are also seemingly unique in that, as far as available data suggest, they are the only group in western Queensland to have used stone in their construction of gunyahs (huts), despite similar environmental and geographic conditions in adjacent areas to the east (Diamantina National Park) and south (Mithaka Country). Here we describe 70 stone-based huts spread across four site complexes on Marion Downs Station and use these to underpin discussions about Pitta Pitta lifeways in the late Holocene.

Taxonomic revision of Australian <i>Erythrophleum</i> (Fabaceae: Caesalpinioideae) including description of two new species

The genus <i>Erythrophleum</i> Afzel ex R.Br. is revised for Australia and three species are recognised, all previously included in <i>E. chlorostachys</i> (F.Muell.) Baill. <i>Erythrophleum arenarium</i> R.L.Barrett & M.D.Barrett is described as a new species to accommodate populations from desert sands of the Great Sandy Desert and Dampier Botanical Districts in north-western Australia, parapatric to the remaining species. <i>Erythrophleum pubescens</i> R.L.Barrett & M.D.Barrett is described as a new species spanning tropical Australia, and is sympatric with <i>E. chlorostachys sensu stricto</i> in the Northern Territory and adjacent areas of Western Australia and Queensland. Morphological examination has shown these three taxa to be consistently distinct across their respective ranges. Analyses of the nuclear ribosomal <i>ITS1</i> region recovered three well-supported clades corresponding to the three morphologically defined species, and <i>ITS1</i> has utility as a marker to separate sterile specimens. <i>Erythrophleum pubescens</i> is widespread in the Australian Monsoon Tropics, from the coast of Western Australia, near Derby, to Cape York Peninsula in northern Queensland. <i>Erythrophleum chlorostachys</i> is also widespread, from the eastern Kimberley Region, in Western Australia, to the Gulf of Carpentaria, in northern Queensland. A lectotype is chosen for <i>Laboucheria chlorostachya</i> F.Muell. Full descriptions, illustrations of key features and identification keys are provided for the three Australian species. A summary of the significant utilisation of <i>Erythrophleum</i> species is presented.

Delineating spatial use combined with threat assessment to aid critical recovery of northeast Australia’s endangered hawksbill turtle, one of western Pacific's last strongholds

The current rate of decline in the globally significant western Pacific hawksbill turtle nesting population on Milman Island on the northern Great Barrier Reef (neQLD) suggests that it could be functionally extinct within a decade. Yet a poor understanding of the relative importance and spatial distribution of threats to this population has been a major impediment to recovery actions. For the first time, we assess all threats to the neQLD stock using a combination of a post-hatchling dispersal model, new satellite tracking of post-nesting migrations and a comprehensive review of existing data. We overlay migration routes and foraging areas from the satellite tracking data with spatially referenced threat layers to analyse threat exposure. We found all tracked hawksbills remained in Australian waters, with migration to foraging areas in Queensland including western Cape York to western Torres Strait (n = 8), and eastern Cape York to eastern Torres Strait (n = 5). These results underscore the critical importance of foraging habitats in Queensland (particularly western Queensland) to the Millman Island nesting population. In contrast, the Lagrangian post-hatchling dispersal model predicted a concentration of turtles in the Torres Strait to Gulf of Papua region, with most final positions in Australian waters (63%), followed by Papua New Guinea (31%), Solomon Islands (3%), Indonesia (2%), Vanuatu (0.49%), New Caledonia (1%). Even though 37% of post-hatchling turtles were predicted to recruit to foraging areas outside of the Australian Exclusive Economic Zone (EEZ), none of the 25 turtles tracked left the Australian EEZ (13 in this study and 12 previously). This suggests that survival to breeding is low for turtles outside of the Australian EEZ, but other explanations are discussed. No single pervasive threat was identified in the threat risk assessment however, fisheries (bycatch/ghost gear) interactions, direct harvesting and climate change were considered to have the potential to impede recovery or result in further decline in the population. Fisheries and harvesting should be the priorities for immediate management actions. The lack of spatial protection in foraging habitats in western Queensland was identified as a major policy gap requiring immediate attention if this population’s trajectory is to be reversed and remain one of western Pacific’s strongholds.

Adaptations to scale-up an early childhood education and care physical activity intervention for real-world availability — Play Active

BackgroundAdaptations for scale-up are ubiquitous but are rarely described in detail. Adaptations may be a key reason for the “scale-up penalty” which is when there is a reduction in intervention effect size following scale-up. The Play Active intervention consists of a physical activity policy for early childhood education and care (ECEC) services, with accompanying implementation support strategies. It was first implemented with 81 ECEC services in Perth, Western Australia, in 2021 — with significant positive changes in physical activity practice uptake. The aim of this paper is to describe the extent, type, fidelity consistency, goals, size, scope, and proposed impact of proposed adaptations to the implementation support strategies for scaling-up Play Active.MethodsProposed adaptations were defined as planned changes, made prior to making the intervention available. The authors created a list of adaptations from a comparison of the Play Active implementation support strategies, before and after adaptation for proposed statewide availability across Western Australia, Queensland and South Australia, Australia. We used the Framework for Reporting Adaptations and Modifications-Enhanced Implementation Strategies (FRAME-IS) to code adaptations to implementation support strategies. Three authors coded each adaptation and rated their size, scope and proposed impact.ResultsFifty-three adaptations to Play Active were identified. Most (68%) were proposed for the ‘content’ of implementation strategies, including aspects of their delivery. In practice, this involved changing the delivery mode of implementation support strategies from phone call and email support, to website-based delivery. More than half (56%) of adaptations involved ‘adding elements’ for scale-up. Most adaptations were ‘fidelity consistent’ (95%). The main goals for adaptations were related to ‘increasing the acceptability, appropriateness, or feasibility’ (45%), ‘decreasing the costs’ (19%) and ‘increasing adoption of the evidence-based practice’ (19%). Adaptations were small to medium in size, with most proposed to have a positive (87%) or neutral (8%) effect on the effectiveness of the intervention, rather than negative (4%).ConclusionsA large number of small, fidelity-consistent, adaptations were proposed for Play Active scale-up. Overall, the process of reporting adaptations was found to be feasible. To understand the impact of these adaptations, it will be important to re-evaluate implementation, effectiveness and process outcomes, at-scale.

Lime stabilised road batters: A laboratory simulation of site flood conditions using a customised erosion apparatus and sample digitisation

The structural benefits of lime stabilisation on clayey soil are widely appreciated. However, its potential in surface erosion contexts, particularly for road batters, has had less consideration. Compared to conventional concrete or vegetative batter protection, lime stabilisation could be a cost-efficient option in Western Queensland; where large road distances experience severe and variable flooding, funding is limited, vegetation is seasonal, and clayey soils are prevalent. The present study assesses the feasibility of trialling 6.7 km of lime stabilised road batters in the Flinders Highway in Western Queensland. Soils sampled from the site were treated with varying percentages of Quicklime and tested in a customised erosion apparatus, labelled the Surface Erosion Apparatus (SEA). With the aid of an ANSYS model, the SEA was designed to simulate shear stress acting along the batter during the 1 % Annual Exceedance Probability (AEP) flood at the project location (as estimated with a TULOW model). The SEA preserves the eroded surface, which facilitated a time-lapse observation of erosion and a post-erosion sample digitisation method to plot the Erosion Function. All levels of lime stabilisation recorded approximately ten times less erosion than untreated samples under 1 % AEP conditions, with an estimated Erosion Category of Low or Very Low Erodibility. Conclusive trends from the laboratory simulation suggested that lime stabilised road batters would be suitable for the trial project.

Untangling two complementary camera trapping data sets to identify patterns in feral cat activity around a known night parrot population in western Queensland

Feral cats (Felis catus) are a significant predator of native birds in Australia, and a recognised predator for the endangered night parrot (Pezoporus occidentalis). We examined camera trapping data from 2014 to 2020 collected at the Pullen Pullen (night parrot) reserve in south-western Queensland to investigate the spatial and temporal patterns of feral cat activity. These data were collected from two discrete periods, with slightly different foci, and we undertook careful data exploration and refinement to identify a consistent data set. We modelled the relationship between the camera detections and a range of environmental, spatial, and temporal parameters, using logistic regression and two selection criteria (Akaike’s and Bayesian). The final parsimonious model identified that feral cat detection probability decreased with increasing ruggedness and increased as distance to creek lines decreased. Feral cat detection probability also declined over time from camera deployment. In each model the variance component estimates suggested that some influences on cat detection probability remain unexplained. Regardless, our results provide further data on feral cat activity, and therefore information to focus and improve the management of this threat to the night parrot and other significant species on this conservation reserve.

Avian assemblages are maintained after aerial applications of ULV fenitrothion for control of the Australian plague locust (Chortoicetes terminifera (Walker)) in arid and semiarid agroecosystems

Context Risk assessments currently undertaken to approve pesticides for use against locusts in Australia are predominated by laboratory-generated data, often collected from non-endemic species. Very little information exists concerning the potential ecological effects of insecticides used for locust control. Aim To determine the effect of aerial ultra-low volume (ULV) applications of the organophosphorous insecticide, fenitrothion (used for locust control), on avian assemblages in arid and semiarid agro-ecosystems. Methods Avian abundance was surveyed in pesticide-exposed and unexposed locations during standard locust control operations, using fenitrothion, in western New South Wales and Queensland in the spring and summer of 1996, 1997 and 2000, using a transect-point method. Temporal changes in assemblages were analysed using multi-dimensional ordination (MDS) and permutational analysis of variance (PERMANOVA) with PRIMER (V7). Key results Avian assemblages varied over time, independent of pesticide application, reflecting significant redistribution and mobility of birds across a highly disturbed agricultural landscape, irrespective of pesticide exposure. Additionally, pesticide exposure did not affect species abundance or diversity. Conclusions There was no evidence that ultra-low volume (ULV) applications of fenitrothion, currently used in locust control, are impacting avian assemblages, despite previous research indicating that individual birds co-occurring with spray operations suffer suppressions in the enzymatic biomarker for OP exposure, plasma acetylcholinesterase (AChE). Implications Although the risk to avian assemblages associated with the aerial application of locusticides is reduced by the small proportion of the landscape where locust control activities are focused, any change in spray application parameters would necessitate a re-evaluation of the risks associated with insecticide exposure.

Plio–Pleistocene vicariance across arid Australia in the ‘Spiny Knob-tailed Geckos’ (

Across Australia’s monsoon tropics and vast arid zone isolated regions or ‘islands’ of upland or rocky habitat are home to disjunct populations of many taxa of plants and animals. Comparative analyses of lineages that occur across these habitat islands provide opportunities to understand when and how environmental change drove isolation and diversification across arid Australia. Here we present an analysis of mitochondrial genetic diversity across disjunct populations of geckos in the Nephrurus asper group. Dating analyses suggest that disjunct and genetically divergent populations spanning the northern half of Australia diverged through the Plio–Pleistocene. Based on the timing of divergence and current habitat associations we hypothesise that species in this lineage were isolated by the expansion of unsuitable arid-zone habitats from the late Pliocene onwards. Across most areas, these barriers appear to be sandy or stony deserts. However, in eastern Australia genetically divergent populations are separated by grassland on flat vertisol-dominated soils (‘blacksoils’), suggesting that these habitats also expanded during the late Pliocene aridification. Finally, we show that western Queensland populations formerly referred to N. asper are genetically divergent and diagnosable on the basis of colour pattern and, herein, recognise these populations as a distinct species. https://zoobank.org/urn:lsid:zoobank.org:pub:9508CAAA-D014-452D-A3DA-325851615FA7
