This project aims to test how behavioural variation affects invasion success. Invasive species can cause economic and ecological damage. Focused preventive measures are difficult unless we know what makes invasions succeed. The role of behaviour is not yet clear – especially inter-individual behavioural variation within species. Using a known invasive reptile model, this project will determine which relevant behaviours are heritable, and therefore subject to evolutionary selection during introduction, establishment, and spread into new locations. Understanding why some invasive species repeatedly succeed while others fail could improve efforts to limit or prevent the harmful effects of invasion.

该项目旨在测试行为变化如何影响入侵成功。入侵物种会造成经济和生态破坏。除非我们知道是什么使入侵成功，否则很难采取集中的预防措施。行为的作用还不清楚，尤其是物种内个体间的行为变异。利用一种已知的入侵爬行动物模型，该项目将确定哪些相关行为是可遗传的，因此在引入、建立和传播到新地点的过程中，它们受到进化选择的影响。了解为什么一些入侵物种反复成功而另一些却失败了，可以改善限制或防止入侵有害影响的努力。
