Overview, Critical Assessment, and Conservation Implications of Koala Distribution and Abundance
Regional and national surveys provide a broadscale description of the koala's present distribution in Australia. A detailed understanding of its distribution is precluded, however, by past andExpand
Dispersal patterns in a regional koala population in south-east Queensland
Koala dispersal was investigated as part of a detailed ecological study of a nationally significant koala population located 20 km south-east of Brisbane, Queensland, and it is likely that the social behaviour and mating systems of koala populations provide mechanisms for young koalas to disperse.

Temporal expression of G-protein-coupled receptor 54 (GPR54), gonadotropin-releasing hormones (GnRH), and dopamine receptor D2 (drd2) in pubertal female grey mullet, Mugil cephalus.
QPCR results showed that the early stage of puberty in grey mullet is characterized by significantly high levels of expression of GPR54, GnRH and drd2 in the brain relative to the intermediate and advanced stages, except for GnRH1 that increased at the advanced stage ofuberty. Expand
Tree use, diet and home range of the koala (Phascolarctos cinereus) at Blair Athol, central Queensland
Free-ranging koalas (Phascolarctos cinereus) were monitored by means of radio-relocation in the area of Blair Athol Coal Mine and surrounding properties, and patterns of daytime tree use and diet selection varied between individuals inhabiting adjacent communities within the site. Expand
Phylogeographic differentiation in the mitochondrial control region in the koala, Phascolarctos cinereus (Goldfuss 1817)
It is concluded that the appropriate short‐term management unit (MU) for koalas is the local population, and significant differentiation in mtDNA‐haplotype frequencies between localities suggested that little gene flow currently exists among populations. Expand
Genetic variation and structuring in the threatened koala populations of Southeast Queensland
It is likely, therefore, that more recent reductions in population size and restricted gene flow through urbanisation have contributed to the genetic differentiation of koalas in the Koala Coast region. Expand
Food of the platypus (Ornithorhynchus anatinus) with notes on the food of brown trout (Salmo trutta) in the Shoalhaven River, N.S.W
Feeding in the platypus Ornithorhynchus anatinus was investigated by identifying material found in the cheek pouches of animals trapped in nets in a study area on the upper Shoalhaven River, N.S.W.Expand
Low genetic diversity and inbreeding depression in Queensland koalas
The hypothesis that koalas have a history of small population size, resulting in reduced susceptibility to inbreeding depression is suggested, because of the limited data it would be premature to conclude thatKoalas are relatively resistant to the effects of inbreeding. Expand
Breeding dynamics of koalas in open woodlands
The conclusion from this study is that ‘resident’ status among males does not confer any advantage for parentage, and the population at Blair Athol comprise a population in genetic equilibrium. Expand
Spermatogenesis in some Australian marsupials.
From the number of cells labelled in tubular cross-sections at different stages of spermatogenesis 1 hr after an intra-arterial injection of [3H]thymidine, it was concluded that at least four synchronized peaks of mitosis occurred in the sperMatogonia of M. rufogriseus. Expand
