The public's knowledge of and support for conservation of Australia's Tree-Kangaroos

After providing some brief background on Dendrolagus species in Australia, two consecutive surveys of Brisbane’s residents are used to assess public knowledge of tree-kangaroos and the stated degree of support for their conservation in Australia. The responses of participants in Survey I are based on their pre-survey knowledge of wildlife. The same additional set of participants completed Survey II after being provided with information on all the wildlife species mentioned in Survey I. Changes in the attitudes of respondents and their degree of support for the protection and conservation of Australia’s tree-kangaroos are measured, including changes in their contingent valuations and stated willingness to provide financial support for such conservation. Reasons for wanting to protect tree-kangaroos are specified and analyzed. Furthermore, changes that occur in the relative importance of these reasons with increased knowledge are also examined. Support for the conservation of tree-kangaroos is found to increase with the additional knowledge supplied. Furthermore, support for the conservation of Australia’s less well-known tropical mammals is shown to increase relative to better known mammals (icons) present in temperate areas, such as koalas and red kangaroos with this increased knowledge. Possible implications of the results for government conservation policies in Australia are examined.

Drosophilidae (Diptera) of Australia's Northern Territory: Ecology and biogeography

The drosophilid fauna is well documented in eastern Australia but is poorly known in other parts of the continent. This paper summarises what is known of this fauna in the Northern Territory (NT), and includes results from banana trapping in the humid and arid zones. The 42 recorded species include species that breed in fruit, fungi and/or flowers, and a larval predator of scale insects. Drosophilids occur in all three major climate zones (humid, semiarid and arid) but predominate in the humid zone. Banana-attracted species in the humid zone (wet-dry tropics) were common in all sampled habitats: urban, rainforest and open woodland. They included predominantly urban and/or rainforest species. Of the species collected in open woodland, some are likely to be breeding there, whereas others may have been intercepted during movement across the area. The semiarid fauna is a depauperate version of that found in the humid region. Only three species have been recorded in the arid region: an endemic arid specialist, and two cosmopolitan species (D. simulans and D. melanogaster ) in urban Alice Springs. Overall, the NT drosophilid fauna represents a depauperate version of that found in eastern Australia, probably because of climatic factors and natural barriers to range expansion. There is little evidence of regional endemism, with probably only one (and at most three) species endemic to the NT, and no evidence of independent, natural dispersion from nearby Indonesia.

Commonwealth of Australia: July to December 2001

The six-month period from July to December 2001 was an extraordinary phase in Australia’s political history. Until 26 August, when 460 asylum seekers were rescued from their sinking vessel off the Western Australian coast, there was nothing to suggest that politics in Australia would be any different from the usual round of policy pronouncements, routine attacks by the opposition, and the occasional headlinegrabbing scandal. It seemed, as the Australian’s international editor Paul Kelly wrote, that tax would dominate the 2001 federal election campaign (21-22 July 2001). Once the asylum seekers had been rescued by the Norwegian freighter Tampa and refused entry to Australia, however, tax declined in significance. The ramifications of the Tampa incident and its aftermath were still engaging the Australian polity when, on 11 September, terrorists hijacked four passenger jets in the United States and flew two of them into the World Trade Centre in New York, one into the Pentagon, and crashed another in Pennsylvania, killing, it was estimated, more than 6000 people. Both incidents changed Australian politics. The extent and significance of the changes remain to be fully seen, but one short-term effect was to boost significantly the government’s chances of re-election.

Spondylostrobus F. Mueller: operculate fruits of an extinct dicotyledon from the mid-Tertiary of Australia

Spondylostrobus F. Mueller, which accommodates operculate fruit-stones reported only from the mid-Tertiary of Australia, is redefined on the basis of type and other specimens of the type species, S. smythii F. Mueller, and of specimens included in S. rozefeldsii sp. nov. The globose to ellipsoidal fruits have 3-6 locules symmetrically disposed around a massive fibrous axis. Each locule has a single anatropous ovule, axile placentation, and a dorsal germination operculum that extends from near the base to the apex. In possessing these characters Spondylostrobus more closely resembles operculate fruits within the tribe Spondiadeae (Anacardiaceae) than operculate fruits of other dicotyledonous families. Spondylostrobus has widespread distribution in Oligocene-Miocene sediments of eastern Australia. At many localities it is associated with fruit-stones having affinities with extant taxa that now occur in rainforests, monsoonal forests, and fringing communities of northern Australia.
