Population dynamics and prey selection of native and introduced predators during a rodent outbreak in arid Australia
There is considerable potential for food-based competition between the kite and introduced mammalian predators, particularly the red fox and house cat, in arid Australia.
The ecological effects of providing resource subsidies to predators
The extent to which human-provided foods are utilised by terrestrial mammalian predators across the globe is reviewed and whether these resources have a direct impact on the ecology and behaviour of predators and an indirect impact on other co-occurring species is assessed.
Bird assemblages of arid Australia: Vegetation patterns have a greater effect than disturbance and resource pulses
The influence of size differntial on agonistic behaviour in the freshwater crayfish, Cherax cuspidatus (Decapoda: Parastacidae)
The agonistic behaviour of juvenile pairs of intermoult freshwater crayfish Cherax cuspidatus, interacting over space in experimental containers, was examined and the influence of prior experience as dominants or subordinates on the behaviour of contestants during these encounters appeared the most likely explanation.
Effects of avian mobbing on roost use and diet of powerful owls, Ninox strenua
The species in this study took a high risk by mobbing a very large predator, but benefited by greatly reducing their chances of predation, thus reducing the chances of an owl being detected by potential mobbers.
Dietary overlap between the nocturnal letter-winged kite Elanus scriptus and barn owl Tyto alba during a rodent outbreak in arid Australia
TEMPORAL PATTERNS OF BATS IN THE TOP END OF THE NORTHERN TERRITORY, AUSTRALIA
Abstract Temporal activity patterns of microchiropteran bats were assessed at 4 scales (hourly, nightly, monthly, and yearly) in the Top End of the Northern Territory, Australia, in relation to…
Spatial ecology of the mulgara in arid Australia: impact of fire history on home range size and burrow use
It is concluded that mulgaras do not select the dense cover of mature spinifex habitat, and might be subjected to increased risk from introduced predators, especially following fire.

Abstract Patterns in the composition of assemblages of microbat species sampled during the late dry season (the ‘build‐up’) in north Australian savannas were assessed against a range of…
Changes in richness and abundance of rodents and native predators in response to extreme rainfall in arid Australia
The dramatic spatial and temporal variation in rainfall and the resource pulses which these trigger provide a challenge for predicting consumer-primary productivity dynamics especially in arid…
