Abstract

Soil fungi play indispensable roles in all ecosystems including the recycling of organic matter and interactions with plants, both as symbionts and pathogens. Past observations and experimental manipulations indicate that projected global change effects, including the increase of CO2 concentration, temperature, change of precipitation and nitrogen (N) deposition, affect fungal species and communities in soils. Although the observed effects depend on the size and duration of change and reflect local conditions, increased N deposition seems to have the most profound effect on fungal communities. The plant-mutualistic fungal guilds - ectomycorrhizal fungi and arbuscular mycorrhizal fungi - appear to be especially responsive to global change factors with N deposition and warming seemingly having the strongest adverse effects. While global change effects on fungal biodiversity seem to be limited, multiple studies demonstrate increases in abundance and dispersal of plant pathogenic fungi. Additionally, ecosystems weakened by global change-induced phenomena, such as drought, are more vulnerable to pathogen outbreaks. The shift from mutualistic fungi to plant pathogens is likely the largest potential threat for the future functioning of natural and managed ecosystems. However, our ability to predict global change effects on fungi is still insufficient and requires further experimental work and long-term observations.

全球变化下土壤中的真菌群落。
土壤真菌在所有生态系统中发挥着不可或缺的作用,包括有机物质的循环和与植物的相互作用,无论是作为共生体还是病原体。过去的观测和实验操作表明,预估的全球变化效应,包括CO2浓度的增加、温度的升高、降水和氮沉降的变化,会影响土壤中的真菌物种和群落。虽然观察到的影响取决于变化的大小和持续时间,并反映了当地的条件,但氮沉降的增加似乎对真菌群落的影响最为深远。植物共生真菌群落——外生菌根真菌和丛枝菌根真菌对全球变化因子的响应尤其明显,其中氮沉降和气候变暖的不利影响似乎最大。虽然全球变化对真菌生物多样性的影响似乎有限,但多项研究表明,植物病原真菌的丰度和扩散都在增加。此外,因干旱等全球变化引起的现象而削弱的生态系统更容易受到病原体爆发的影响。从共生真菌到植物病原体的转变可能是对自然和管理生态系统未来功能的最大潜在威胁。然而,我们预测全球变化对真菌影响的能力仍然不足,需要进一步的实验工作和长期观察。引用本文:Baldrian P, Bell-Dereske L, Lepinay C, Větrovský T, Kohout P(2022)。全球变化下土壤中的真菌群落。真菌学研究103:1-24。doi: 10.3114 / sim.2022.103.01。

期刊介绍: The international journal Studies in Mycology focuses on advancing the understanding of filamentous fungi, yeasts, and various aspects of mycology. It publishes comprehensive systematic monographs as well as topical issues covering a wide range of subjects including biotechnology, ecology, molecular biology, pathology, and systematics. This Open-Access journal offers unrestricted access to its content. Each issue of Studies in Mycology consists of around 5 to 6 papers, either in the form of monographs or special focused topics. Unlike traditional length restrictions, the journal encourages submissions of manuscripts with a minimum of 50 A4 pages in print. This ensures a thorough exploration and presentation of the research findings, maximizing the depth of the published work.
