The number of epizootics in amphibian populations caused by viruses of the genus is increasing worldwide. Yet, causes for pathogen emergence are poorly understood. Here, we confirmed that the (CMTV) and (FV3) are responsible for mass mortalities in Iberia since the late 1980s. Our results illustrate the Iberian Peninsula as a diversity hotspot for the highly virulent CMTV. Although this pattern of diversity in Europe is consistent with spread by natural dispersal, the exact origin of the emergence of CMTV remains uncertain. Nevertheless, our data allow hypothesizing that the Iberian Peninsula might harbor the ancestral population of CMTVs that could have spread into the rest of Europe. In addition, we found that climate warming could be triggering the CMTV outbreaks, supporting its endemic status in the Iberian Peninsula.
该属病毒引起的两栖动物种群 epizootics 的数量在全球范围内正在增加。然而，病原体出现的原因却知之甚少。在这里，我们证实了自 20 世纪 80 年代末以来，（CMTV）和（FV3）是伊比利亚大规模死亡事件的罪魁祸首。我们的结果表明伊比利亚半岛是高毒力 CMTV 的多样性热点地区。尽管欧洲这种多样性模式与自然扩散传播一致，但 CMTV 出现的确切起源仍不确定。然而，我们的数据使我们能够推测伊比利亚半岛可能蕴藏着 CMTV 的祖先种群，这些种群可能已经扩散到欧洲其他地区。此外，我们发现气候变暖可能正在引发 CMTV 疫情，这支持了其在伊比利亚半岛的地方病地位。 （注：原文中“epizootics”可能是一个特定的专业术语，在没有更多背景信息的情况下，暂时保留英文未翻译，你可根据实际情况进一步完善。）
