ABSTRACT
Our ability to predict the identity of future invasive alien species is largely based upon knowledge of prior invasion history. Emerging alien species - those never encountered as aliens before - therefore pose a significant challenge to biosecurity interventions worldwide. Understanding their temporal trends, origins, and the drivers of their spread is pivotal to improving prevention and risk assessment tools. Here, we use a database of 45,984 first records of 16,019 established alien species to investigate the temporal dynamics of occurrences of emerging alien species worldwide.
