Improving the anti-predator responses of native mammals

点击翻译按钮获取中文摘要

Predation by introduced cats and foxes causes extinction and decline in Australian mammals. Protecting threatened mammals inside fenced sanctuaries is effective but they can become overpopulated, inbred and more naive to predators over time. This leads to a dwindling hope of ever restoring them to their natural habitat. Previous research has shown that exposing threatened mammals to low levels of cat predation in large fenced paddocks improves their anti-predator behaviour, changes their physical appearance and improves survival. This grant seeks to understand the mechanisms (genetic/learning) behind these changes in order to harness and upscale our results and facilitate co-existence between native mammals and introduced predators.
