Exploring species diversity along elevational gradients is important for understanding the underlying mechanisms. Our study focused on analyzing the species diversity of fungal communities and their subcommunities at different trophic and taxonomic levels across three high mountains of the Korean Peninsula, each situated in a different climatic zone. Using high-throughput sequencing, we aimed to assess fungal diversity patterns and investigate the primary environmental factors influencing fungal diversity. Our results indicate that soil fungal diversity exhibits different elevational distribution patterns on different mountains, highlighting the combined effects of climate, soil properties, and geographic topology. Notably, the total and available phosphorus contents in the soil emerged as key determinants in explaining the differences in diversity attributed to soil properties. Despite the varied responses of fungal diversity to elevational gradients among different trophic guilds and taxonomic levels, their primary environmental determinants remained remarkably consistent. In particular, total and available phosphorus contents showed significant correlations with the diversity of the majority of the trophic guilds and taxonomic levels. Our study reveals the absence of a uniform diversity pattern along elevational gradients, underscoring the general sensitivity of fungi to soil conditions. By enriching our understanding of fungal diversity dynamics, this research enhances our comprehension of the formation and maintenance of elevational fungal diversity and the response of microbial communities in mountain ecosystems to climate change. This study provides valuable insights for future ecological studies of similar biotic communities.
探索沿海拔梯度的物种多样性对于理解其潜在机制至关重要。我们的研究聚焦于分析朝鲜半岛三座位于不同气候区的高山上不同营养级和分类水平的真菌群落及其子群落的物种多样性。通过高通量测序，我们旨在评估真菌多样性模式并调查影响真菌多样性的主要环境因素。我们的结果表明，土壤真菌多样性在不同的山上呈现出不同的海拔分布模式，突出了气候、土壤性质和地理拓扑结构的综合影响。值得注意的是，土壤中的总磷和有效磷含量成为解释因土壤性质导致的多样性差异的关键决定因素。尽管不同营养类群和分类水平的真菌多样性对海拔梯度的响应各不相同，但其主要环境决定因素却显著一致。特别是，总磷和有效磷含量与大多数营养类群和分类水平的多样性呈现出显著相关性。我们的研究揭示了沿海拔梯度不存在统一的多样性模式，强调了真菌对土壤条件的普遍敏感性。通过丰富我们对真菌多样性动态的理解，这项研究增进了我们对海拔真菌多样性的形成和维持以及山区生态系统中微生物群落对气候变化的响应的理解。这项研究为未来类似生物群落的生态学研究提供了有价值的见解。
