Current biosecurity efforts are failing to keep pace with globalization, revealing critical gaps in our understanding and response to invasions. Here, we identify four priority areas to advance invasion science in the face of rapid global environmental change. First, invasion science should strive to develop a more comprehensive framework for predicting how the behavior, abundance, and interspecific interactions of non-native species vary in relation to conditions in receiving environments and how these factors govern the ecological impacts of invasion. A second priority is to understand the potential synergistic effects of multiple co-occurring stressors— particularly involving climate change—on the establishment and impact of non-native species. Climate adaptation and mitigation strategies will need to consider the possible consequences of promoting non-native species, and appropriate management responses to non-native species will need to be developed. The third priority is to address the taxonomic impediment. The ability to detect and evaluate invasion risks is compromised by a growing deficit in taxonomic expertise, which cannot be adequately compensated by new molecular technologies alone. Management of biosecurity risks will become increasingly challenging unless academia, industry, and governments train and employ new personnel in taxonomy and systematics. Fourth, we recommend that internationally cooperative biosecurity strategies consider the bridgehead effects of global dispersal networks, in which organisms tend to invade new regions from locations where they have already established. Cooperation among countries to eradicate or control species established in bridgehead regions should yield greater benefit than independent attempts by individual countries to exclude these species from arriving and establishing.pp.119-141en© The Author(s) or their institution(s).biosecurityclimate changeecological impactinvasive speciesmanagementrisk assessmentJournal Article10.1139/er-2020-00881208-60532022-03-23ANZSRC::410202 Biosecurity science and invasive species ecologyANZSRC::410102 Ecological impacts of climate change and ecological adaptationANZSRC::310307 Population ecologyANZSRC::410404 Environmental managementANZSRC::4101 Climate change impacts and adaptationANZSRC::4104 Environmental managementANZSRC::4105 Pollution and contaminationhttps://creativecommons.org/licenses/by/4.0/Attribution
