两栖动物在全球范围内正以前所未有的速度减少。为了指导保护工作，正在进行全球两栖动物评估，以确定物种之间的生物多样性和进化关系，以及两栖动物种群和物种健康。现代分子方法正在促进这种表征，我们重点介绍了快速增加数据可用性以进行分类区分的技术。当确定了多样性的特征，并确定了种群和最容易受到衰退或灭绝影响的物种时，就必须了解导致衰退的因素，以制定缓解战略。我们讨论了分子方法及其应用，以解决一些两栖动物衰退的主要假说，包括栖息地丧失、新出现的传染病、化学污染物和全球气候变化。
Amphibians are declining globally at unprecedented rates. To direct conservation efforts, global amphibian assessments are being conducted to characterize biodiversity and evolutionary relationships among species, as well as amphibian population and species' health. Modern molecular methods are facilitating such characterization, and we highlight techniques for rapidly increasing the availability of data for making taxonomic distinctions. When diversity is characterized, and populations and the species most vulnerable to declines or extinctions are identified, it is then critical to understand factors causing declines to develop mitigation strategies. We discuss molecular approaches and their applications for addressing some of the leading hypotheses for amphibian declines, including habitat loss, emerging infections diseases, chemical contaminants, and global climate change.
