Abstract

The relationship between aquatic environmental DNA (eDNA) assemblages in rivers and the surrounding terrestrial fungal communities has been poorly investigated. Here, we focused on fungi that form soft sporocarps (soft fungi). Two years of sporocarp and aquatic eDNA sampling were conducted at a fragmented forest site, and the soft-fungal assemblages and their temporal dynamics were compared between these two sample types. Aquatic eDNA yielded approximately 1.5 times the operational taxonomic units (OTUs) compared to sporocarps and covered approximately half of the OTUs from sporocarp samples. Lineages that seldom form sporocarps or form inconspicuous sporocarps were successfully detected from aquatic eDNA. Although the OTU composition differed between sporocarp and aquatic eDNA, their temporal dynamics were similar, with both showing a 1-year periodicity. Aquatic eDNA provides insights into fungal diversity and temporal dynamics, but does not fully reflect terrestrial fungi diversity.

水生真菌环境DNA组合是否反映了周围陆生孢子体群落?

河流中水生环境DNA (eDNA)组合与周围陆生真菌群落之间的关系研究甚少。在这里，我们关注的是形成软孢子囊的真菌(软真菌)。在一个破碎的森林样地进行了两年的孢子皮和水生eDNA采样，比较了这两种样品类型的软真菌组合及其时间动态。水生eDNA产生的操作分类单位(OTUs)约为孢子皮的1.5倍，约占孢子皮样品中OTUs的一半。从水生生物的eDNA中成功地检测到很少形成子果皮或形成不明显的子果皮的谱系。尽管子皮和水生eDNA的OTU组成不同，但它们的时间动态相似，都表现出1年的周期性。水生eDNA提供了真菌多样性和时间动态的见解，但不能完全反映陆生真菌的多样性。

期刊介绍： Fungal Ecology publishes investigations into all aspects of fungal ecology, including the following (not exclusive): population dynamics; adaptation; evolution; role in ecosystem functioning, nutrient cycling, decomposition, carbon allocation; ecophysiology; intra- and inter-specific mycelial interactions, fungus-plant (pathogens, mycorrhizas, lichens, endophytes), fungus-invertebrate and fungus-microbe interaction; genomics and (evolutionary) genetics; conservation and biodiversity; remote sensing; bioremediation and biodegradation; quantitative and computational aspects - modelling, indicators, complexity, informatics. The usual prerequisites for publication will be originality, clarity, and significance as relevant to a better understanding of the ecology of fungi.
