Islands support the greatest numbers of endemic species but are highly vulnerable to human activities. In particular, the introduction of invasive, predatory mammals (e.g., rodents) has resulted in sharp declines of island fauna due to a lack of evolved behavioral capacities to avoid depredation. Because of this, invasive species are considered to be one of the most detrimental impacts to biodiversity. To combat this biodiversity loss, the eradication of invasive mammals is now a primary conservation tool, with > 700 attempts globally. However, mammal eradications are predicated on the assumption that islands will naturally return to their pre-invaded condition. Yet many …
