节肢动物拥有复杂的微生物群,在宿主健康中起着关键作用。虽然多重因素,比如宿主物种和饮食,塑造节肢动物的微生物群,它们对野生昆虫群落聚集的影响在很大程度上仍然未知。在这项研究中,我们调查了9种具有共同柑橘类水果饮食的同胞野生昆虫的细菌和真菌群落组装。来源追踪分析表明,这些昆虫不同程度地从柑橘果实中获取了一些细菌和真菌。尽管共享共同的饮食会导致微生物群趋同,多样性,composition,在接受调查的昆虫群体中,细菌和真菌群落的网络差异很大。零模型分析表明,随机过程,特别是扩散限制和漂移,是构建昆虫细菌和真菌群落的主要驱动因素。重要的是,每个群落聚集过程的影响因宿主物种而异。因此,我们提出了一个推测性的观点,即微生物组和分枝杆菌组组装的宿主特异性在野生昆虫中普遍存在,尽管它们共享相同的区域物种库。总的来说,这项研究巩固了宿主物种在塑造微生物群和分枝杆菌群中的重要性,为它们在野生昆虫中的组装机制提供了新的见解。
目的:由于微生物组已被证明会影响昆虫的适应性,对社区组装的机械理解具有潜在的重要应用,但在很大程度上仍未探索。在本文中,我们调查了9种具有共同饮食的同伴野生昆虫的细菌和真菌群落组装。主要发现表明,随机过程驱动了9种同胞野生昆虫物种中微生物群和真菌群的分化。这些发现为野生昆虫中微生物组和分枝杆菌的组装机制提供了新的见解。
Arthropods harbor complex microbiota that play a pivotal role in host fitness. While multiple factors, like host species and diet, shape microbiota in arthropods, their impact on community assembly in wild insects remains largely unknown. In this study, we surveyed bacterial and fungal community assembly in nine sympatric wild
insect species that share a common citrus fruit diet. Source tracking analysis suggested that these insects acquire some bacteria and fungi from the citrus fruit with varying degrees. Although sharing a common diet led to microbiota convergence, the diversity, composition, and network of both bacterial and fungal communities varied significantly among surveyed
insect groups. Null model analysis indicated that stochastic processes, particularly dispersal limitation and drift, are primary drivers of structuring
insect bacterial and fungal communities. Importantly, the influence of each community assembly process varied strongly depending on the host species. Thus, we proposed a speculative view that the host specificity of the microbiome and mycobiome assembly is widespread in wild insects despite sharing the same regional species pool. Overall, this research solidifies the importance of host species in shaping microbiomes and mycobiomes, providing novel insights into their assembly mechanisms in wild insects.
OBJECTIVE: Since the microbiome has been shown to impact insect fitness, a mechanistic understanding of community assembly has potentially significant applications but remains largely unexplored. In this paper, we investigate bacterial and fungal community assembly in nine sympatric wild
insect species that share a common diet. The main findings indicate that stochastic processes drive the divergence of microbiomes and mycobiomes in nine sympatric wild
insect species. These findings offer novel insights into the assembly mechanisms of microbiomes and mycobiomes in wild insects.
