The management of landscapes for biological conservation and ecologically sustainable natural resource use are crucial global issues. Research for over two decades has resulted in a large literature, yet there is little consensus on the applicability or even the existence of general principles or broad considerations that could guide landscape conservation.(More)
Biodiversity continues to decline in the face of increasing anthropogenic pressures such as habitat destruction, exploitation, pollution and introduction of alien species. Existing global databases of species' threat status or population time series are dominated by charismatic species. The collation of datasets with broad taxonomic and biogeographic(More)
The highly distinctive and mostly endemic Australian land mammal fauna has suffered an extraordinary rate of extinction (>10% of the 273 endemic terrestrial species) over the last ∼200 y: in comparison, only one native land mammal from continental North America became extinct since European settlement. A further 21% of Australian endemic land mammal species(More)
How effective are large, well-resourced protected areas at achieving biodiversity conservation goals? In this study we critically review biodiversity research and management practice in two of the world’s premier savanna reserves (Kruger National Park, South Africa and Kakadu National Park, Australia) by exploring management approaches to three shared(More)
In recent analysis of factors related to nomadism in birds of semi-arid southern Australia, Allen and Saunders concluded that nomadism was related particularly to proximity to natural breaks in an ordered sequence of body weights across species, with less important relationships with weight per se and diet. That analysis is flawed by incorrect dietary(More)
Sixty-two percent of 26 wild caught Gouldian finches (Erythrura gouldiae) were infected with Sternostoma tracheacolum, a parasitic rhinonyssid mite. The intensity of infection was higher in adult finches than juveniles, and higher in juvenile females than juvenile males. Histopathological investigation of wild Gouldian Finches revealed bronchopneumonia and(More)
Fire is an integral part of savanna ecology and changes in fire patterns are linked to biodiversity loss in savannas worldwide. In Australia, changed fire regimes are implicated in the contemporary declines of small mammals, riparian species, obligate-seeding plants and grass seed-eating birds. Translating this knowledge into management to recover(More)
A case of herpes simplex genitalis producing radiculomyelopathy with urinary retention is reported. The patient was treated with adenosine arabinoside intravenously and made a complete recovery over 4 weeks. Although herpes simplex genitalis is common, neurological sequelae, particularly cord involvement, are distinctly rare. It should, nevertheless, be(More)
Extinctions typically have ecological drivers, such as habitat loss. However, extinction events are also influenced by policy and management settings that may be antithetical to biodiversity conservation, inadequate to prevent extinction, insufficiently resourced, or poorly implemented. Three endemic Australian vertebrate species-the Christmas Island(More)
