This project aims to investigate the spread of cane toads through southern Australia, an invasion front that has attracted far less research than the same species’ expansion through tropical regions, even though toads severely impact native wildlife in both areas. This project expects to generate new knowledge to determine why the rate of toad invasion is so much slower in New South Wales than in the tropics, and how best to modify newly-developed approaches to toad control to the conditions in southern Australia. Expected outcomes include predicting future trajectories of expansion, and identifying optimal approaches to toad control and impact mitigation. This should provide significant benefits for biodiversity conservation.

该项目旨在调查甘蔗蟾蜍在澳大利亚南部的传播，这一入侵前沿吸引的研究远远少于同一物种在热带地区的扩张，尽管蟾蜍严重影响了这两个地区的本地野生动物。该项目预计将产生新的知识，以确定为什么新南威尔士州的蟾蜍入侵速度比热带地区慢得多，以及如何最好地修改新开发的蟾蜍控制方法，以适应澳大利亚南部的条件。预期成果包括预测未来的扩张轨迹，并确定控制蟾蜍和减轻影响的最佳方法。这将为保护生物多样性带来巨大的好处。
