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 […]

The numerical response: rate of increase and food limitation in herbivores and predators

Two types of numerical response function have evolved since Solomon first introduced the term to generalize features of Lotka-Volterra predator-prey models: (i) the demographic numerical response, which links change in […]

Heterogeneity in vertebrate and invertebrate herbivory and its consequences for New Zealand mistletoes

Vertebrate herbivores generally have greater effects than invertebrates on plants. However, few studies have investigated the effects of both invertebrate and vertebrate herbivores on a single plant species. In New […]

Exploitation of brushtail possum populations in theory and practice

Recent trends in the New Zealand fur industry, based on introduced brushtail possums (), include an increasing proportion of small skins and some evidence of declining catch per unit effort, […]

Effects of intensive trapping on breeding and age structure of brushtail possums, Trichosurus vulpecula, on Kapiti Island, New Zealand

Between 1980 and 1986, introduced Australian brushtail possums (Trichosurus vulpecula) were eradicated from Kapiti Island, a 1965 ha nature reserve. The possum population was monitored by live- and kill-trapping, before […]

Control of the possum (Trichosurus vulpecula) in New Zealand

The Australian brushtail possum continues to be a major pest in New Zealand, despite the substantial export of possum pelts. Possums cause widespread mortality of major food species in podocarp/mixed […]
