Despite the global declines in the rate of amphibians, evaluation of public understanding of the crisis has not yet been carried out. We surveyed visitors (n = 1,293) at 15 zoos in Brazil, New Zealand, and the United Kingdom, using a certainty-based assessment method to compare visitor knowledge of the global amphibian crisis. We further analyzed zoo educational material about amphibians to explore its potential to raise awareness through amphibian-focused environmental education. Visitors in the three countries had relatively little understanding of amphibians and the global amphibian crisis. When the degree of confidence in answering the questions (high, medium, and low) is accounted for, correct answers varied between 28% and 39%. This compared to scores of between 58% and 73% when the degree of confidence in responding was not accounted for. However, specific areas of knowledge (e.g., biology, conservation, biogeography, and conceptual ideas) varied significantly across the countries. Visitors had a weaker grasp of biogeographical and conservation issues than general amphibian biology. Zoo visitors in Brazil knew less about amphibian conservation than those in New Zealand or the United Kingdom. There was less amphibian-focused content in educational materials in zoos in Brazil than there was in the United Kingdom. Improving information about the global amphibian crisis may increase support for future conservation actions. Outreach education is one of the most important approaches in any strategic planning for conservation of species. Amphibian-focused environmental education at institutions such as zoos and aquaria can be a crucial intervention to support amphibian conservation worldwide.

三个国家动物园游客对两栖动物危机的理解比较

尽管全球两栖动物的数量下降，但尚未对公众对危机的理解进行评估。我们调查了巴西、新西兰和英国 15 个动物园的游客（n = 1,293），使用基于确定性的评估方法来比较游客对全球两栖动物危机的了解。我们进一步分析了有关两栖动物的动物园教育材料，以探索其通过以两栖动物为重点的环境教育提高认识的潜力。这三个国家的游客对两栖动物和全球两栖动物危机的了解相对较少。当考虑到回答问题（高、中、低）的置信度时，正确答案在 28% 到 39% 之间变化。相比之下，当不考虑响应的置信度时，得分介于 58% 和 73% 之间。然而，不同国家的特定知识领域（例如生物学、保护、生物地理学和概念思想）差异很大。与一般的两栖动物生物学相比，游客对生物地理和保护问题的了解较弱。与新西兰或英国的游客相比，巴西的动物园游客对两栖动物保护的了解较少。巴西动物园的教育材料中以两栖动物为重点的内容少于英国。改善有关全球两栖动物危机的信息可能会增加对未来保护行动的支持。外展教育是任何物种保护战略规划中最重要的方法之一。
