Abstract

Phyllosphere fungi form close ecological ties with their hosts and participate in multiple ecosystem processes. This research investigated simulated climate change effects of warming and precipitation manipulationon the Aster tataricus fungal community in a Qinghai-Tibetan Plateau alpine meadow. Increased precipitation increased the fungal community diversity and richness indices, but warming had the opposite effect. Warming and precipitation adjustment in combination reduced the fungal community diversity. FUNGuild functional analysis of differences in the leaf fungal community in our study, and linked statistical analysis, determined that increasing precipitation significantly reduced relative abundance of pathogenic fungi and incidence of plant diseases, while warming and decreased precipitation did the opposite. Differences in the leaf fungal community in our study under warming and decreased precipitation would be predicted to increase incidence of plant diseases. These climate change simulations improve awareness of future plant disease risks in natural plant communities and provide opportunities to develop responses.

青藏高原高寒草甸紫檀叶层真菌组成、多样性和功能对人工增温和降水调节的响应

叶层真菌与寄主形成密切的生态联系，参与多种生态系统过程。本研究模拟了青藏高原高寒草甸气候变暖和降水对紫檀真菌群落的影响。降水量的增加增加了真菌群落的多样性和丰富度指数，但气候变暖却产生了相反的影响。温暖和降水调节相结合降低了真菌群落的多样性。FUNGGuild函数分析了我们研究中叶片真菌群落的差异，并进行了关联统计分析，确定增加降水量显著降低了病原真菌的相对丰度和植物病害的发生率，而变暖和减少降水量则相反。在我们的研究中，在变暖和降水减少的情况下，叶真菌群落的差异将增加植物疾病的发生率。这些气候变化模拟提高了自然植物群落对未来植物疾病风险的认识，并为制定应对措施提供了机会。

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.
