New craniodental remains of Wakaleo alcootaensis (Diprotodontia: Thylacoleonidae) a carnivorous marsupial from the late Miocene Alcoota Local Fauna of the Northern Territory, Australia.

ABSTRACT: New jaws and teeth referable to the rare thylacoleonid marsupial Wakaleo alcootaensis are figured and described. The species is the geologically youngest known member of the genus and is only known from the late Miocene Alcoota Local Fauna of the Northern Territory, Australia. A revised diagnosis of the species is presented which is found to be morphologically distinct from its congeners. W. alcootaensis can be distinguished from other species of Wakaleo by its greater size, deeply recessed masseteric fossa, more steeply angled I1, loss of P2, greater P3 to M1 ratio and loss of M3. Several characters of W. alcootaensis, including the increase in size, steeply angled I1, increase of the relative size of P3, and reduction of the molar row are present in at least some species of Thylacoleo. Phylogenetic analysis suggests that these character states are convergences and that there was parallel evolution in these two thylacoleonid lineages.

Project description:Introduction:Originally piloted as a multi-departmental project within the Government of South Australia, SA NT DataLink is now the key provider of data linkage services in South Australia, the Northern Territory of Australia and the Commonwealth of Australia, enabling academics and policy makers to undertake research, policy, planning and evaluation. Approach:Uniquely governed by a broad range of consortium partners, SA NT DataLink's business model operates with flexibility to adapt to researcher priorities and government requirements. Its Data Linkage Unit routinely links data from over 50 sources with more than 57 million records on approximately 2.9 million individuals. It arguably provides the broadest range of linked data sources in Australia, focusing on administrative datasets and clinical registries from various health and human services domains. Operating in strict adherence with the separation principal, SA NT DataLink's Data Integration Unit separately manages anonymised clinical and service use data in collaboration with the respective data custodians through the Custodian Controlled Data Repository, allowing approved analysts to efficiently access high quality linked anonymised data. To protect individual privacy throughout the process of data linkage and data provision, SA NT DataLink's processes align with state, territory and federal privacy legislations. Operating consistently with National Health and Medical Research Council guidelines, linkage projects are subject to approvals by the relevant data custodians and approved Human Research Ethics Committees. Noteworthy Outputs:SA NT DataLink has provided linkage services to over 160 data linkage projects, informing nationally significant research and policy initiatives, including initiatives to improve indigenous children's hearing and child development. Conclusion:To respond to a changing data linkage landscape, SA NT DataLink is continuously reviewing and improving its systems, linkage processes and governance, addressing administrative, funding, data access, social licence and data linkage challenges and opportunities to meet increasing demand and new business developments.

Project description:BackgroundAustralian surveillance data document higher rates of sexually transmissible infections (STIs) among young Aboriginal people (15-29 years) in remote settings than non-Aboriginal young people. Epidemiological data indicate a substantial number of young Aboriginal people do not test for STIs. Rigorous qualitative research can enhance understanding of these findings. This paper documents socio-ecological factors influencing young Aboriginal people's engagement with clinic-based STI testing in two remote settings in the Northern Territory, Australia.MethodsIn-depth interviews with 35 young Aboriginal men and women aged 16-21 years; thematic analysis examining their perceptions and personal experiences of access to clinic-based STI testing.ResultsFindings reveal individual, social and health service level influences on willingness to undertake clinic-based STI testing. Individual level barriers included limited knowledge about asymptomatic STIs, attitudinal barriers against testing for symptomatic STIs, and lack of skills to communicate about STIs with health service staff. Social influences both promoted and inhibited STI testing. In setting 1, local social networks enabled intergenerational learning about sexual health and facilitated accompanied visits to health clinics for young women. In setting 2, however, social connectedness inhibited access to STI testing services. Being seen at clinics was perceived to lead to stigmatisation among peers and fear of reputational damage due to STI-related rumours. Modalities of health service provision both enhanced and inhibited STI testing. In setting 1, outreach strategies by male health workers provided young Aboriginal men with opportunities to learn about sexual health, initiate trusting relationships with clinic staff, and gain access to clinics. In setting 2, barriers were created by the location and visibility of the clinic, appointment procedures, waiting rooms and waiting times. Where inhibitive factors at the individual, social and health service levels exist, young Aboriginal people reported more limited access to STI testing.ConclusionsThis is the first socio-ecological analysis of factors influencing young Aboriginal people's willingness to undertake testing for STIs within clinics in Australia. Strategies to improve uptake of STI testing must tackle the overlapping social and health service factors that discourage young people from seeking sexual health support. Much can be learned from young people's lived sexual health experiences and family- and community-based health promotion practices.
