Population dynamics, diet and aspects of the biology of feral cats and foxes in arid South Australia

Average cat and fox densities at Roxby Downs, in northern South Australia, of 0.8 and 0.6 km–2 respectively, determined through spotlight counts over a 10-year period, probably considerably underestimate true densities. Peak rabbit populations coincided with high fox numbers, which probably suppressed cat densities. Cat abundance peaked when fox numbers were low but rabbit numbers […]

Impact of rabbit haemorrhagic disease on introduced predators in the Flinders Ranges, South Australia

The impact of rabbit haemorrhagic disease (RHD) on the population dynamics and diet of foxes and feral cats was studied in the Flinders Ranges, South Australia. Populations of both foxes and cats decreased substantially some 6–10 months after the advent of RHD, when rabbit numbers were reduced by 85%. The diet of foxes changed as […]

Feeding ecology and population dynamics of the feral cat (Felis catus) in relation to the availability of prey in central-eastern New South Wales

The diet of feral cats (Felis catus) was studied at Lake Burrendong, central-eastern New South Wales, from July 1994 to June 1997. Mammals were the major prey in 499 scats that were analysed. Rabbits (Oryctolagus cuniculus) were the staple prey, while carrion was an important secondary food. Invertebrates, other mammalian prey, vegetation, birds and reptiles […]

Population dynamics of three species of dasyurid marsupials in arid central Australia: a 10-year study

This study investigated the population dynamics of three species of dasyurid marsupials in sand ridge habitat of the Simpson Desert, western Queensland, over a 10-year period between March 1990 and December 1999. The lesser hairy-footed dunnart (Sminthopsis youngsoni), was captured most consistently over the period of study, followed by the wongai ningaui (Ningaui ridei), and […]

Variation in the ecology of Trichosurus: its adaptive significance

Although the common brushtail possum (Trichosurus vulpecula) was introduced to New Zealand over 100 years ago to establish a fur industry, its subsequent abundance, especially in indigenous broadleaf/podocarp forests, has had detrimental consequences. This review outlines the damage caused by possums and the development of a control-oriented management policy. Research on population dynamics, behaviour, and […]
