Call Out and Listen In: A New Way to Detect and Control Invasive Species

本项目旨在利用新颖的声学技术探测和捕获入侵蛙种，以保护本地物种。入侵青蛙在世界范围内是一个不受重视但严重的生态问题，因为它们是贪婪的捕食者，对本地物种通常是有毒的。雄性青蛙通过鸣叫来吸引配偶，并回应它们听到的叫声。利用新的声学技术，这些行为可以用来探测物种并吸引怀孕的雌性进行移除。该项目旨在将预警系统（电子监听）和陷阱（呼叫和捕捉）结合起来，这可以针对任何入侵的青蛙进行定制，并使用它来检测和清除甘蔗蟾蜍，特别是在低密度种群中。

This project aims to use novel acoustic techniques to detect and capture invasive frog species to protect native species. Invasive frogs are an under-appreciated but serious ecological problem worldwide, because they are voracious predators and are often toxic to native species. Male frogs call to attract mates, and answer calls they hear. Using new acoustic technologies, these behaviours can be exploited to detect species and attract gravid females for removal. This project aims to combine an early warning system (electronic listening) and trap (calling and catching), which can be customised to any invasive frog, and use it to detect and remove cane toads, especially in low density populations.
