摘要
背景：捕食者与被捕食者之间的相互作用及其动态变化为病毒在生物体内传播提供了频繁的机会，从而影响了生物体内的病毒多样性。然而，人们很少研究捕食者的食物多样性与病毒多样性之间的联系。食肉蝙蝠（Ia io）的食物多样性表现出一种季节性模式。虽然它们中的大多数在夏季主要捕食昆虫，但在春季和秋季主要捕食夜间迁徙的鸟类：结果：本研究利用病毒元转录组测序对中国西南地区夏秋季三个虹鳉种群的 RNA 病毒组进行了表征。我们还在虹鳟种群水平上整合了 DNA 代谢编码和病毒元转录组测序技术，研究了食性多样性与 RNA 病毒多样性之间的关系。我们发现了属于 35 个已知 RNA 病毒科的 55 个已知属。除了发现人们通常关注的哺乳动物相关病毒外，我们还发现了大量昆虫相关病毒和一些鸟类相关病毒。我们发现，与昆虫相关的病毒在夏季较多，而与鸟类相关的病毒则主要在秋季被发现，这可能是由于 I. io 对猎物选择的季节性差异造成的。此外，我们还发现猎物多样性与病毒总多样性之间存在明显的正相关。猎物组成越相似，病毒总组成越相似，潜在新病毒的数量也越高。我们还发现，Picornaviridae的相对丰度随着猎物多样性和体重的增加而增加：结论：本研究发现，RNA病毒多样性与鳌虾的食性多样性之间存在重要联系。结果表明，捕食者与猎物之间相互作用的动态变化可能会促进病毒在生物体内频繁传播。视频摘要
The links between dietary diversity and RNA virus diversity harbored by the great evening bat (Ia io).
Background: Predator‒prey interactions and their dynamic changes provide frequent opportunities for viruses to spread among organisms and thus affect their virus diversity. However, the connections between dietary diversity and virus diversity in predators have seldom been studied. The avivorous bats, Ia io, show a seasonal pattern of dietary diversity. Although most of them primarily prey on insects in summer, they mainly prey on nocturnally migrating birds in spring and autumn.
Results: In this study, we characterized the RNA virome of three populations of I. io in Southwest China during summer and autumn using viral metatranscriptomic sequencing. We also investigated the relationships between dietary diversity and RNA virus diversity by integrating DNA metabarcoding and viral metatranscriptomic sequencing techniques at the population level of I. io. We found 55 known genera belonging to 35 known families of RNA viruses. Besides detecting mammal-related viruses, which are the usual concern, we also found a high abundance of insect-related viruses and some bird-related viruses. We found that insect-related viruses were more abundant in summer, while the bird-related viruses were predominantly detected in autumn, which might be caused by the seasonal differences in prey selection by I. io. Additionally, a significant positive correlation was identified between prey diversity and total virus diversity. The more similar the prey composition, the more similar the total virus composition and the higher the count of potential new viruses. We also found that the relative abundance of Picornaviridae increased with increasing prey diversity and body mass.
Conclusions: In this study, significant links were found between RNA virus diversity and dietary diversity of I. io. The results implied that dynamic changes in predator-prey interactions may facilitate frequent opportunities for viruses to spread among organisms. Video Abstract.
期刊介绍：
Microbiome is a journal that focuses on studies of microbiomes in humans, animals, plants, and the environment. It covers both natural and manipulated microbiomes, such as those in agriculture. The journal is interested in research that uses meta-omics approaches or novel bioinformatics tools and emphasizes the community/host interaction and structure-function relationship within the microbiome. Studies that go beyond descriptive omics surveys and include experimental or theoretical approaches will be considered for publication. The journal also encourages research that establishes cause and effect relationships and supports proposed microbiome functions. However, studies of individual microbial isolates/species without exploring their impact on the host or the complex microbiome structures and functions will not be considered for publication. Microbiome is indexed in BIOSIS, Current Contents, DOAJ, Embase, MEDLINE, PubMed, PubMed Central, and Science Citations Index Expanded.
