Open AccessInvasion syndromes: a systematic approach for predicting biological invasions and facilitating effective management
Our ability to predict invasions has been hindered by the seemingly idiosyncratic context-dependency of individual invasions. However, we argue that robust and useful generalisations in invasion science can be...
