Predicting Effects of Predation on Conservation of Endangered Prey
The observed predation curves conformed to the predictions of predator-prey theory and suggest a protocol for an experimental management program for the conservation of sensitive prey species.
Extreme climatic events shape arid and semiarid ecosystems
6 Climatic changes associated with the El Nino Southern Oscillation (ENSO) can have a dramatic impact on ter- restrial ecosystems worldwide, but especially on arid and semiarid systems, where
Keystone effects of an alien top-predator stem extinctions of native mammals
This study provides evidence that an alien top predator can assume a keystone role and be beneficial for biodiversity conservation, and also that mammalian carnivores more generally can generate strong trophic cascades in terrestrial ecosystems.
Evaluating the role of the dingo as a trophic regulator in Australian ecosystems
Three broad questions are proposed to clarify not only the impacts of dingoes at all trophic levels, but also the mechanisms by which these impacts occur; the design of appropriate experiments is discussed, using principles that may also be applied to investigate species interactions on other continents.
Impact of exotic generalist predators on the native fauna of Australia

It is concluded that feral cats and especially foxes have major negative impacts on certain small and medium-sized native vertebrates in Australia, whereas dingoes could have positive effects on smaller native species if they significantly suppress populations of foxes and cats.
Analysis of factors implicated in the recent decline of Australia's mammal fauna
To assess whether eight factors thought to be involved in the extinction process can explain the pattern of recent decline in Australia's mammal fauna, a large number of them related to climate change are considered.
Habitat fragmentation and vertebrate species richness in an urban environment
Mammalian species richness within patches decreased with increasing percentage of barren ground per patch, with proximity to buildings, and with patchiness in the total vegetation cover, but increased with increasing density of vegetation in the layer 21-50 cm above ground.
