我们调查了东南亚蝙蝠中的寄生虫和病毒丰富度。我们使用系统发育比较分析测试寄生虫丰富度的决定因素。蝙蝠的区域分布形状解释了病毒和寄生虫的丰富度。蝙蝠分布的未来变化可能会改变它们的病毒和寄生虫丰富度。在过去的十年里，人们对蝙蝠传播的疾病和寄生虫的兴趣超过了对人类健康的关注。然而，蝙蝠宿主物种中寄生虫多样性的驱动因素以及寄生虫丰富度和新出现的风险之间的联系都没有得到充分研究。因此，我们的目的是探索因素，解释宏观和微观寄生虫物种丰富的蝙蝠从东南亚，一个热点的新兴传染病。首先，我们确定了蝙蝠物种，需要增加采样工作的病原体发现。我们的方法突出了病原体调查的差异物种在同一属，如菊头蝠和狐蝠。其次，使用独立对比方法进行比较分析，可以确定解释蝙蝠寄生虫和病毒多样性的可能因素。我们的研究结果表明，蝙蝠分布的形状，蝙蝠分布的碎片化指数，寄生虫多样性的关键作用，与病毒和内寄生虫物种丰富度的下降。我们讨论了我们的研究如何有助于更好地了解寄生虫物种丰富度和出现之间的联系。
We investigated the parasite and viral richness in bats from Southeast Asia. We tested determinants of parasite richness using phylogenetic comparative analyses. Viral and parasite richness were explained by area distribution shape of bats. Future changes in bat distribution may alter their viral and parasite richness. Interest in bat-borne diseases and parasites has grown in the past decade over concerns for human health. However, the drivers of parasite diversity among bat host species are understudied as are the links between parasite richness and emerging risks. Thus, we aimed at exploring factors that explain macro and microparasite species richness in bats from Southeast Asia, a hotspot of emerging infectious diseases. First, we identified bat species that need increased sampling effort for pathogen discovery. Our approach highlights pathogen investigation disparities among species within the same genus, such as Rhinolophus and Pteropus. Secondly, comparative analysis using independent contrasts method allowed the identification of likely factors explaining parasite and viral diversity of bats. Our results showed a key role of bat distribution shape, an index of the fragmentation of bat distribution, on parasite diversity, linked to a decrease for both viral and endoparasite species richness. We discuss how our study may contribute to a better understanding of the link between parasite species richness and emergence.
