Globalization has driven a rise in the frequency of invasive species, with negative consequences for biodiversity, food production, and human health. In many cases, climate change has also contributed to the spread of introduced species by expanding their geographical ranges. Understanding the population structure and phylogenetic history of invasive populations is crucial for reconstructing their initial introduction and subsequent spread. Meanwhile, genetic monitoring of established populations can help detect new introduction events. Genetic tools can also be used to control invasive species, for example through gene drive or the release of sterile individuals.
This Collection will feature articles on the genetics of invasive species, including research using molecular tools to illuminate their invasion histories, track their population trajectories, and combat their spread.
