Rare And Endangered

We report the rediscovery of the rare and endangered native rodent, the plains mouse (Pseudomys australis) in New South Wales (NSW). Two plains mice were trapped in the far west of the state at Fowlers Gap Arid Zone Research Station and another in the NSW section of the Strzelecki Desert. Until these captures, the plains mouse was thought to have been extinct in NSW. Subfossil records indicate that these observations are within the pre-European settlement range of the species. It is uncertain whether these captures represent a range expansion from known populations in northern South Australia or reflect a local refuge population. Ensuring the conservation of P. australis in NSW requires further study to determine its distribution and the factors influencing its abundance.

This book provides readers with a unique understanding of the ways in which Aboriginal people interacted with their environment in the past at one particular location in western New South Wales. It also provides a statement showing how geoarchaeology should be conducted in a wide range of locations throughout Australia. One of the key difficulties faced by all those interested in the interaction between humans and their environment in the past is the complex array of processes acting over different spatial and temporal scales. The authors take account of this complexity by integrating three key areas of study – geomorphology, geochronology and archaeology – applied at a landscape scale, with the intention of understanding the record of how Australian Aboriginal people interacted with the environment through time and across space. This analysis is based on the results of archaeological research conducted at the University of New South Wales Fowlers Gap Arid Zone Research Station between 1999 and 2002 as part of the Western New South Wales Archaeology Program. The interdisciplinary geoarchaeological program was targeted at expanding the potential offered by archaeological deposits in western New South Wales, Australia. The book contains six chapters: the first two introduce the study area, then three data analysis chapters deal in turn with the geomorphology, geochronology and archaeology of Fowlers Gap Station. A final chapter considers the results in relation to the history of Aboriginal occupation of Fowlers Gap Station, as well as the insights they provide into Aboriginal ways of life more generally. Analyses are well illustrated through the tabulation of results and the use of figures created through Geographic Information System software.

Petrogale xanthopus still occurs over most of its former range in South Australia. It is widespread in the Flinders Ranges, where almost 200 colonies are now known, and is locally common in areas of both the Rinders Ranges and Olary Hills. Six colonies are currently known in the western Gawler Ranges with an outlying population on Carriewerloo Station only 50 km west of Port Augusta. Seven colonies have been found in the Olary Hills, to the north and north-west of Olary. The species has suffered a major decline in abundance since European settlement, having become extinct locally throughout this range. Hunting for skins, competition with introduced herbivores for food and shelter, and predation by foxes seem to be the main reasons for this decline. However, it is still not possible to say whether the species currently has a decreasing population and is at risk, is in equilibrium, or is increasing. Information published in this paper and current studies in South Australia and New South Wales should soon determine this.

Tachyglossus Aculeatus

ABSTRACTEchidnas (Tachyglossus aculeatus) are found Australian-wide and appear to be remarkably well-adapted to arid zones, yet, nearly all echidna research has been conducted in temperate, tropical and alpine zones. This study investigated the home range and movement of echidnas in western New South Wales. Radio telemetry tracking was used to locate the echidnas daily during the study period (March-May 2019 and August 2019); the home range was 1.47± 1.21 km2. This is over twice the reported home range of temperate environments (>0.65 km2) suggesting that echidnas exhibit larger home ranges in arid zones. This study provides insight into the movement and home range of echidnas in arid zones, revealing that desert echidnas have large home ranges, dependent on the availability of resources.

Abundant Population

We conducted a search of the historical records for any mention of hairy-nosed wombats in order to establish their likely distribution at the time of European settlement. The evidence suggests that there were two main groups of southern hairy-nosed wombats (Lasiorhinus latifrons) that were separated by Spencer Gulf in South Australia. The western group extended to Balladonia in Western Australia, while the eastern group extended along the Murray River to Euston in New South Wales. The Queensland population of northern hairy-nosed wombats (Lasiorhinus krefftii) was geographically large but highly patchy, and there was an abundant population in the New South Wales Riverina. Both species experienced a population decline between 1870 and 1920, with the main influences thought to be competition from rabbits and control actions by landholders. Our findings suggest that the ongoing control of rabbits via methods that do not harm wombats is critical for wombat conservation today. We also suggest that hairy-nosed wombats may be sensitive to climate change, and recommend more research on this topic.

For 3 years numbers and species of blowflies breeding in carcasses and on live merino sheep were studied at the University of New South Wales Arid Zone Research Station at Fowlers Gap, to determine which species initiated blowfly strike on sheep and how Lucilia cuprina (Wiedemann) maintained its population throughout the year; particularly whether it could complete its life cycle on carcasses. Larvae taken from struck sheep showed L. cuprina to be the dominant species in >87% of strikes. Native calliphorids, Calliphora nociva Hardy, Calliphora augur (Fabr.), and Calliphora stygia (Fabr.) were present in about 7% of strikes sampled, usually in association with L. cuprina. In a regularly inspected small mob (c. 70) of sheep, incidence of covert strike was higher than incidence of overt strike, supporting the view that a grazier's estimate of flystrike in the flock would almost always be an underestimate. On carcasses, the secondary strike native blowfly, Chrysomys rufijacies (Macquart), was produced in very large numbers. Some native primary strike Calliphora spp. were produced from some carcasses in the colder months, but no L. cuprina was produced from either small or large carcasses (sheep, kangaroos, rabbits) at any time. However, larvae of L. cuprina were recovered from live sheep at all times of the year, indicating that L. cuprina is an obligate parasite of live sheep in the arid zone.

Constitutional systems of Westminster heritage are increasingly moving towards fixed-term parliaments to, amongst other things, prevent the Premier or Prime Minister opportunistically calling a ‘snap election’. Amongst the Australian states, qualified fixed-term parliaments currently exist in New South Wales, South Australia and Victoria. Queensland, Tasmania and Western Australia have also deliberated over whether to establish similar fixed-term parliaments. However, manner and form provisions in those states' constitutions entrench the Parliament's duration, Governor's Office and dissolution power. In Western Australia and Queensland, unlike Tasmania, such provisions are doubly entrenched. This article considers whether these entrenching provisions present legal obstacles to constitutional amendments establishing fixed-term parliaments in those two states. This involves examining whether laws fixing parliamentary terms fall within section 6 of the Australia Acts 1986 (Cth) & (UK). The article concludes by examining recent amendments to the Electoral Act 1907 (WA) designed to enable fixed election dates in Western Australia without requiring a successful referendum.

The Relation Between the Food of the Australian Barracouta, Thyrsites atun (Euphrasen), and Recent Fluctuations in the Fisheries

The diet of surface-swimming Australian barracouta was studied from over 10,000 stomachs. The principal prey organisms in Bass Strait are the euphausiid Nyctiphanes australis Sars, the anchovy Engraulis australis (White), and young barracouta, in that order; and in eastern Tasmania Nyctiphanes, Engraulis, and the sprat Clupea bassensis McCulloch, in that order. The pilchard Sardinops neopilchardus (Steindachner) is not an important item of the diet in these regions although it is so in New South Wales, South Australia, and Western Australia. The jack mackerel Trachurus declivis Jenyns is a significant item in eastern Tasmania and New South Wales but not in Bass Strait. These and other features of the fish diet of the barracouta reflect actual availability of the various small fish species in the waters. Barracouta eat Nyctiphanes by herding them into dense masses (or finding them already concentrated) and swallowing them. The movements of the anchovy make it unavailable to Bass Strait and eastern Tasmanian barracouta for much of the summer and autumn period, when the barracouta are thus dependent upon Nyctiphanes for the bulk of their food. A close positive relationship between the availability of barracouta and Nyctiphanes might therefore be expected at those seasons. There is evidence of such a relationship between mean availability (catch per boat-month) of barracouta and mean percentage of barracouta stomachs containing Nyctiphanes, at those seasons, from year to year. For southern Victorian coastal waters both show a downward trend from 1948-49 to 1950-51 and then an upward trend to 1953-54; for eastern Tasmania both show a downward trend (for autumn only) from 1949-50 through 1952-53. The records of catch per boat-month furnish independent evidence that the main variations in this index were effects of availability (population distribution or behaviour) rather than abundance (population size), at least for southern Victoria. It is therefore considered that when scarcity of barracouta occurs in summer and autumn in the coastal fishing areas it may be due to scarcity of Nyctiphanes, forcing the fish to go offshore for this food which is known to be available there. This would take the fish out of range of the fishermen.
