Abstract Three male and two female ship rats (Rattus rattus) were radio‐tagged and tracked in beech (Nothofagus) forest in the Eglinton Valley, Fiordland, New Zealand over two field periods in 1996 and 2000. The home range of each animal was calculated using the minimum convex polygon method. Ranges of three male rats were 7.5, 9.1, and 11.4 ha whereas those of the female rats were 0.89 and 0.27 ha. The home ranges recorded for male rats were considerably larger than those reported from other… 
Home range and population density of black rats (Rattus rattus) on a seabird island: a case for a marine subsidised effect?
Comparisons with other New Zealand islands and mainland sites did not clearly support nor negate the ‘island syndrome’ in ship rats in New Zealand, although large increases in population densities on Big South Cape Island/Taukihepa did not influence home range sizes.
Denning behaviour of ship rats (Rattus rattus) on Taukihepa, a seabird breeding island
Den sites of 14 ship rats were located daily during the rat breeding season on Taukihepa (Big South Cape), a seabird island southwest of Rakiura (Stewart Island), in contrast to other New Zealand studies, no arboreal dens were found.
Home Range and Movements of Roof Rats (Rattus rattus) in an Old-growth Riparian Forest, California
Abstract Information on the spatial ecology of nonnative roof rats (Rattus rattus) is important for developing management strategies to reduce their impacts on native wildlife in riparian habitats.
Effect of grazing on ship rat density in forest fragments of lowland Waikato, New Zealand
An uncalibrated, rapid (one-night) index of ship rat density, using baited tracking tunnels set in a 50 × 50 m grid, showed a promising relationship with the number of rats killed per hectare over the first six nights, up to tracking index values of c.
How elevation affects ship rat (Rattus rattus) capture patterns, Mt Misery, New Zealand
In this study, ship rats were captured in traps set along a 2 km elevational transect in beech forest and adjacent alpine tussock at Mt Misery from 1974 to 1993, providing an important insight into the drivers of ship rat elevational distribution.
The ecology of ship rats (Rattus rattus) on Ponui Island: implications for North Island brown kiwi (Apteryx mantelli)
Investigation into the population dynamics and habitat use of a ship rat population on Ponui Island found population density was higher than estimates made in the same area seven months previously, and ship rats were highly arboreal in December.
Using passive detection devices to monitor occupancy of ship rats (Rattus rattus) in New Zealand temperate rainforest
Given the linear relationship between ship rat tracking and trapping rates, the reported trends in occupancy are realistic, and more accurate than tracking rate estimates, and the current monitoring methods should be improved.
Home ranges of introduced rats on Christmas Island: a pilot study.
Home ranges of male rats were significantly larger compared with their female counterparts, with male rats maintaining larger home ranges in urban areas compared with seabird colonies, and a possible correlation between the spatial distribution of food resources and home range size is suggested.
Spatial Ecology of Invasive Black Rats (Rattus rattus) On San Clemente Island, California
Better understanding of black rat spatial ecology will allow for improved rat-control efforts to facilitate ESA-listed taxa conservation efforts on SCI.
Distribution of small mammals in five New Zealand forest habitats
It is suggested that in most cases the density index is not a rigorous measure of small mammal populations, despite being often used in small mammal studies.


Ranging behaviour of forest-dwelling ship rats, Rattus rattus, and effects of poisoning with brodifacoum.
Radio‐tracking of rats in primary forest at Rotoehu, North Island detected no significant change in home range area or utilisation, arboreality, or movements, and further research is required to determine if rats prey on other fauna while fatally intoxicated or cause secondary poisoning after being eaten by other predators.
There have been few attempts to study home range size and habitat use by ship rats in New Zealand forests and their impact was emphatically demonstrated more recently when they invaded the Big South Cape Islands.
Spread of the ship rat (Rattus r. rattus L.) III New Zealand
Abstract It has usually been assumed that both ship rats (R. rattus) and Norway rats (R. norvegicus) reached New Zealand at the time of Cook's voyages or soon afterwards and had become generally
Successful recovery of North Island kokako Callaeas cinerea wilsoni populations, by adaptive management
Reduction of pests, especially brushtail possums Trichosurus vulpecula and ship rats Rattus rattus, to very low levels resulted in significant increases in kokako chick output and adult density in all three study populations.
Large scale stoat control to protect mohua (Mohoua ochrocephala) and kaka (Nestor meridionalis) in the Eglinton Valley, Fiordland, New Zealand.
To enhance the breeding success and survival of kaka (Nestor meridionalis) and mohua (Mohoua ochrocephala), we initiated stoat (Mustela erminea) control in the Eglinton Valley (13 000 ha), Fiordland,
Home‐range analysis using radio‐tracking data–a review of problems and techniques particularly as applied to the study of mammals
The review showed that even 25 years after the first radio-tracking studies, in the majority of papers there was still insufficient attention given to accurate and sufficient data collection, and to using appropriate and sophisticated analytical techniques to assess home-range size and configuration.
Techniques for trapping and tracking stoats (Mustela erminea); a review, and a new system
Two new kinds of traps and a footprint recording system are described; these techniques can provide useful information on the population structure, feeding habits, and natural movements of stoats.
