Predators can strongly influence the microhabitat use and foraging behaviour of prey. In a large-scale replicated field experiment in East Gippsland, Australia, we tested the effects of reduced alien red fox (Vulpes vulpes) and alien wild dog (Canis lupus familiaris) abundance (treatment) on native bush rat (Rattus fuscipes) behaviour. Bush rats are exposed to two main guilds of predators, namely mammalian carnivores and birds of prey. Tracking rat movements using the spool-and-line technique… 
Fire affects microhabitat selection, movement patterns, and body condition of an Australian rodent (Rattus fuscipes)
The effects of fire on bush rat resource selection, movement, body condition, and abundance were likely driven by several linked factors including limited access to shelter and food due to the loss of understory vegetation and heightened levels of perceived predation risk.
Understory cover increases patch use in rodent Thrichomys fosteri
It is suggested that open areas may be dangerous to the predators of T. fosteri, making these habitats safer than the forests for this rodent, and that this tropical species adheres to global patterns, but only at microhabitat level.
Domestic cats and dogs create a landscape of fear for pest rodents around rural homesteads
It is found that the presence of cats and dogs at the same homestead significantly reduced activity and increased GUDs (i.e. increased perception of foraging cost) of pest rodent species.
Microhabitat selection by small mammals in response to fire
ABSTRACT Understanding how fire influences animal behaviour, such as movement and resource selection, is important for ecosystem management because it can improve our capacity to predict how species
nvasive rat space use on tropical islands : Implications for ait broadcast
Testing for active effects of habitat and season that may alter black rat (Rattus rattus) space use dynamics and inform rodent management n two tropical islands identifies winter as the recommended treatment eriod on both islands and discusses bait broadcast strategies.
The effect of rabbit-warren ripping on the consumption of native fauna by foxes in the arid zone of New South Wales
The diet of foxes in an arid zone site in western New South Wales was analysed from the contents of scats collected every three months from October 1986 to July 1989. Fox diet comprised 27%


Predation by introduced foxes on native bush rats in Australia: do foxes take the doomed surplus?

The results suggest that where predation pressure is low, not all predation mortality will be additive to prey populations even if it results from a predator introduced to the ecosystem, and indiscriminate control of introduced predators is unlikely to produce uniform benefits for all the species they prey upon.
The effects of owl predation on the foraging behavior of heteromyid rodents
The differences in morphology between pocket mice and kangaroo rats do appear to influence their behavioral responses to predatory risk, and this work provides direct experimental evidence on the role of predatory risk in affecting the foraging behavior of three species of heteromyid rodents.
Effects of predation and habitat structure on the population dynamics of house mice in large outdoor enclosures
This is the first study with mammals that confirms the importance of refuges from predators for prey populations, with mice having lower survival in low grassland pens than in high refuge pens.
Responses of Australian Bush Rats, Rattus fuscipes, to the Odor of Introduced Vulpes vulpes

Trapping success of wild bush rats was compared between clean traps and traps scented with fox odor, set along creeks in Namadgi National Park in southeastern Australia, and results showed no avoidance responses with similar numbers of captures in clean and fox-scented traps.
Do native Australian small mammals avoid faeces of domestic dogs? Responses of Rattus fuscipes and Antechinus stuartii
Bush Rats Rattus fuscipes, the most abundant species captured, showed no aversion to dog faecal odours across 20 sampled sites and entered control and dog-scented traps equally, and faeces from domestic dogs dropped in native habitats appear unlikely to deter small native fauna due to predation hazards.
Predation risk and habitat selection of Australian house mice , Mus domesticus, during an incipient plague: desperate behaviour due to food depletion
It is concluded that during high densities mice experience a strong trade-off between food and safety and take greater risks in all habitats and within each habitat at the microhabitat level.
Different microhabitat preferences of field and bank voles under manipulated predation risk from an alien predator
Responses of native voles to removal of analien predator, the American mink, on small islands in the outer archipelago of the Baltic Sea, SW Finland provide novel evidence for a microhabitat shift of native prey animals induced by an alien predator.
The influence of predation risk on foraging behaviour of brushtail possums in Australian woodlands
The results suggest that habitat at the stand-level was more important and the non-lethal effects of foxes in different habitats may need to be taken into account when developing conservation strategies for native marsupials.

It is suggested that grouping behaviour is risk sensitive and that some individuals accept higher risks of predation to mitigate other costs of group foraging, and that solitary behaviour increases rather than decreases predation risk.
