Academic literature on the topic 'Earthquakes Northern Territory Tennant Creek Region'

A series of vegetation sites was established in Australia's Northern Territory between Darwin and Tennant Creek, a distance of approximately 1000 km and 7° latitude (12°30'–19°30'S). This region encompasses a strong environmental gradient in mean annual moisture availability (450–1600 mm) whilst remaining within a predominantly summer monsoonal rainfall regime. All sites are within eucalypt-savanna habitats on lighter textured soils (sands–loams). Major changes in family and species representation occur at approximately 16–17° latitude, supporting findings of other workers. Within these eucalypt-savanna communities, the percentage of annual species is consistently around 30% regardless of latitude. However, the distribution of resource allocation strategies used by perennial plants exhibits distinct latitudinal trends. The proportion of deciduous and seasonally perennial species declines with latitude whilst suffrutescent shrub species become increasingly abundant. Species possessing root structures adapted for storage purposes appear to be limited to latitudes north of 15°S.

Five new species of small grass cicadas belonging to the genus Graminitigrina Ewart and Marques are described, together with detailed analyses of their calling songs. Four species occur in Queensland, G. aurora n. sp. from eastern central Queensland near Fairbairn Dam; G. flindensis n. sp. from central Queensland between Hughenden northwards for at least 108 km; G. einasleighi n. sp. from near The Lynd, Einasleigh River, northeastern Queensland; G. selwynensis n. sp. from the Selwyn Range, northwestern Queensland, at locations about 40 km east of Mount Isa and 25 km southwest of Cloncurry, this latter here transferred from G. bowensis Ewart and Marques; G. uluruensis n. sp. from Uluru and the Olgas in southwestern Northern Territory, extending northwards through Tennant Creek and apparently further north to near Larrimah, a linear distance of approximately 1190 km. These new species bring the known Graminitigrina species to ten, all superficially similar in colour and morphology. A key to male specimens is provided for the 10 species. Additional distribution records and additional aural song recordings are presented for G. bowensis, these requiring the transfer of populations previously identified as G. bowensis from Croydon and Georgetown, northern Gulf region, to G. karumbae Ewart and Marques. Detailed comparative analyses, including NMDS analyses, of the songs of all 10 species are provided, which show that the song parameters are appropriate to distinguish the species, although some partial overlap is noted in the waveform plots between the songs of G. uluruensis n. sp. and G. flindensis n. sp. Regional variations of song parameters are noted in the calling songs of most of the species described.

Sufficient, well-maintained housing infrastructure can support healthy living practices for hygiene, safety and nutrition. This article focuses on the relationship between housing and health through a case study in the remote Barkly region in the Northern Territory, Australia. A research partnership between Anyinginyi Health Aboriginal Corporation and academic researchers employed a mixed methodological approach, involving interviews with residents, clinical and outreach staff, and clinical database analysis. The results revealed much higher levels of crowding in remote communities and in Tennant Creek than officially recorded, with up to 22 residents in surveyed households. Interviews with clinicians and public health staff highlighted the impact of crowding on infection transmission, poor sleep and reduced personal safety, and damage to health hardware. The database analysis detailed the types of preventable, hygiene-related infectious diseases that dominated, with over half of the total infectious disease diagnoses being skin, respiratory and ear, nose and throat infections. Repeated infection likely contributes to increased rates of chronic kidney and rheumatic heart diseases. The combined overall findings highlight the parallel conditions of the prevalence of hygiene-related infectious diseases, crowding and environmental health issues (including health hardware). No objective evidence of direct causal relationships was obtained due to the small scale and methodological limitations of the study. More complex future research is outlined in order to understand how to further investigate the burden of disease that the affects morbidity and mortality of Aboriginal Australians, and underlies the urgency for housing policy reform and funding to upgrade housing.<br/><br />Key messages<br/>Housing is an ongoing, unresolved challenge for many remote-living Aboriginal Australians.<br/><br/>Case-study respondents reported waiting seven years for housing and long delays for maintenance.<br/><br/>Non-functioning ‘health hardware’ and crowding increase the risk of transmission of infectious diseases.<br/><br/>Preventable infections are present in many remote Aboriginal households and can contribute to later chronic heart and kidney conditions.
