Unexpected consequences of control: competitive vs. predator release in a four-species assemblage of invasive mammals.
Invasive species are frequently the target of eradication or control programmes to mitigate their impacts. However, manipulating single species in isolation can lead to unexpected consequences forExpand

Chew-track-cards: a multiple-species small mammal detection device
Detecting the presence of invasive mammalian pests is expensive, particularly where multiple species of interest are sympatric, yet is key to determining when, where and how much control to do, andExpand

Ship rat demography and diet following possum control in a mixed podocarp-hardwood forest.
Control of one pest species may permit increases in abundance of other pests, thereby reducing the overall net benefit from pest control. We provide evidence that control of introduced possumsExpand

Effects of spatially extensive control of invasive rats on abundance of native invertebrates in mainland New Zealand forests.
Predation on native fauna by non-native invasive mammals is widely documented, but effects of predation at the population level are rarely measured. Eradication of invasive mammals from islands hasExpand

Effect of prefeeding, sowing rate and sowing pattern on efficacy of aerial 1080 poisoning of small-mammal pests in New Zealand
Context Aerial poisoning using sodium fluoroacetate (1080) is an important but controversial technique used for large-scale control of brushtail possums (Trichosurus vulpecula) and other pests in NewExpand
