如何保护地球上迅速消失的生物多样性是我们这一代人面临的最大挑战之一。在陆生脊椎动物分类群中，两栖动物面临的风险最大，所有已知物种中有41%的物种面临人口下降，三分之一面临灭绝的威胁。尽管许多机构已经做出回应，为几种极度濒危的两栖动物建立了圈养保证群，但如果没有多管齐下的方法，这些保护组织提供的资源将不足以拯救所有“处于危险中”的物种。在世界各地，动物园、水族馆、政府和保护非政府组织都开始建立两栖动物基因库，以永久保护这些极度濒危物种的剩余遗传多样性。一套生物材料已被作为冷冻保存的目标，包括血液、细胞培养物、组织、精子、卵子和胚胎。2010年至2012年期间，举办了几次关于两栖动物基因库和辅助生殖技术的国际研讨会，汇集了两栖动物生态学、生理学和低温生物学领域的顶尖专家，以综合两栖动物遗传资源生物库的新趋势，提供合作机会，并讨论未来的研究方向。下面的审查文件和摘要将提供这些国际研讨会的概要，特别是希望，现实和当前的挑战固有的这一应用研究领域。(C)2013爱思唯尔有限公司保留所有权利。
How to conserve our planet's rapidly disappearing biodiversity is one of the greatest challenges of our generation. Among terrestrial vertebrate taxa, amphibians are most at risk with 41% of all known species experiencing population declines and one-third threatened with extinction. Although many institutions have responded by establishing captive assurance colonies for several critically endangered amphibians, the resources provided by these conservation organizations will not be enough to save all species 'at risk' without a multi-pronged approach. Around the world, zoos, aquariums, governments, and conservation NGOs are beginning to establish amphibian gene banks to conserve, in perpetuity, the remaining extant genetic diversity for many of these critically endangered species. A suite of biomaterials has been targeted for cryoconservation including blood, cell cultures, tissues, spermatozoa, eggs, and embryos. Several international workshops on amphibian gene banking and assisted reproductive technologies have been held between 2010 and 2012, bringing together leading experts in the fields of amphibian ecology, physiology, and cryobiology to synthesize emerging trends for biobanking amphibian genetic resources, provide opportunities for collaboration, and discuss future research directions. The following review paper and summary will provide a synopsis of these international workshops, in particular the hopes, realities, and current challenges inherent to this applied research field.
