在过去的二十年里，许多研究表明，外来捕食者导致了两栖动物种群的下降。实验研究和相关的实地调查都表明，外来鱼类、牛蛙和小龙虾是两栖动物种群下降的主要原因，在某些情况下甚至是当地灭绝的主要原因。其他研究表明，外来捕食者也造成了水生群落的长期变化。最近的研究探讨了移除外来捕食者的可行性，并提供了一些证据表明两栖动物种群可以恢复。如何将过去的研究成果应用于两栖动物种群的恢复将是未来研究的挑战。国际、国家和地方管制外来捕食者的政策应主要以文献中已有的大量科学证据为基础。科学家需要更多地参与决策者，以最有效地改变规范外星捕食者的法律。
Over the last two decades, numerous studies have shown that alien predators contributed to amphibian population declines. Both experimental studies and correlative field surveys implicated alien species of fish, bullfrogs and crayfish as major contributors to amphibian population decline, and in some instances local extinction. Additional studies have demonstrated that alien predators also caused long-term changes in aquatic communities. Recent studies have examined the feasibility of removing alien predators, and provide some evidence that amphibian populations can recover. Applying information gained from past studies to the recovery of amphibian populations will be the challenge of future studies. International, national and local policies that regulate alien predators should be based largely on the body of scientific evidence already in the literature. Scientists need to be more involved with policy-makers to most effectively change laws that regulate alien predators.
