Behavioural variation and the success of invasive animals

点击翻译按钮获取中文摘要

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.
