“…Changes in vegetation types with altitude lead to significant changes in soil fungal community composition, as this is coupled tightly with vegetation properties through host specificity and the production of different organic substrates [ 11 ]. Soil fungal community composition varies significantly along altitude gradients [ 12 , 13 , 14 ]. Since the dominant taxa in soil fungi (taxonomic and trophic mode) exhibit different life strategies, determining the effect of altitude gradients on the dominant taxa may be important for interpreting the altitude patterns of fungal diversity and understanding ecosystem function [ 15 ].…”

Soil fungi play an integral and essential role in maintaining soil ecosystem functions. The understanding of altitude variations and their drivers of soil fungal community composition and diversity remains relatively unclear. Mountains provide an open, natural platform for studying how the soil fungal community responds to climatic variability at a short altitude distance. Using the Illumina MiSeq high-throughput sequencing technique, we examined soil fungal community composition and diversity among seven vegetation types (dry valley shrub, valley-mountain ecotone broadleaved mixed forest, subalpine broadleaved mixed forest, subalpine coniferous-broadleaved mixed forest, subalpine coniferous forest, alpine shrub meadow, alpine meadow) along a 2582 m altitude gradient in the alpine–gorge region on the eastern Qinghai–Tibetan Plateau. Ascomycota (47.72%), Basidiomycota (36.58%), and Mortierellomycota (12.14%) were the top three soil fungal dominant phyla in all samples. Soil fungal community composition differed significantly among the seven vegetation types along altitude gradients. The α-diversity of soil total fungi and symbiotic fungi had a distinct hollow pattern, while saprophytic fungi and pathogenic fungi showed no obvious pattern along altitude gradients. The β-diversity of soil total fungi, symbiotic fungi, saprophytic fungi, and pathogenic fungi was derived mainly from species turnover processes and exhibited a significant altitude distance-decay pattern. Soil properties explained 31.27−34.91% of variation in soil fungal (total and trophic modes) community composition along altitude gradients, and the effects of soil nutrients on fungal community composition varied by trophic modes. Soil pH was the main factor affecting α-diversity of soil fungi along altitude gradients. The β-diversity and turnover components of soil total fungi and saprophytic fungi were affected by soil properties and geographic distance, while those of symbiotic fungi and pathogenic fungi were affected only by soil properties. This study deepens our knowledge regarding altitude variations and their drivers of soil fungal community composition and diversity, and confirms that the effects of soil properties on soil fungal community composition and diversity vary by trophic modes along altitude gradients in the alpine–gorge region.

“…Knowledge of the drivers of fungal community composition and its spatial variation is important given their pronounced effects on various ecosystem processes (Baldrian, 2017; Crowther et al., 2019; Jacoby et al., 2017). Some studies have shown that fungal communities can vary markedly in space, at least for some taxa and guilds, as a function of dispersal limitation, vegetation, soil chemistry and climate (Odriozola et al., 2021; Peay et al., 2007, 2012; Peguero et al., 2021; Talbot et al., 2014; van der Linde et al., 2018; Větrovský et al., 2019). However, it has yet to be determined whether these effects show spatial scale dependence and what such dependence might look like (e.g., compared to that of macroorganisms and other microorganisms, such as bacteria), especially for fungal groups from different ecological guilds and microhabitats.…”

“…In contrast, yeasts are unicellular organisms that share several ecological characteristics with bacteria (Mašínová et al., 2017). These physiological differences between guilds presumably lead to differences in their dispersal capacity and their responses to environmental conditions, which, in turn, lead to different spatial patterns and drivers of community composition (Liang et al., 2023; Odriozola et al., 2020, 2021; Peguero et al., 2021; Soininen et al., 2007; Zinger et al., 2019). Several studies have demonstrated that ECM fungi may show biogeographic patterns similar to those of macroorganisms (Bahram et al., 2012; Peay et al., 2007, 2012), and their geographic distributions can be limited by dispersal (Bahram et al., 2013; Talbot et al., 2014).…”

“…Last, many studies have shown strong covariation between the spatial distribution of ECM fungi and plant community composition, which has been attributed to their plant‐associated lifestyle (Bahram et al., 2013; Liang et al., 2023; Odriozola et al., 2020; Peay et al., 2013; van der Linde et al., 2018). Yet, yeasts and saprotrophs sometimes also show associations with tree identity and plant community composition, even though they are free‐living organisms not directly dependent on the association with a host plant (Mašínová et al., 2017; Odriozola et al., 2021; Urbanová et al., 2015).…”

AimHow community composition varies in space and what governs the variation has been extensively investigated in macroorganisms. However, we have only limited knowledge of microorganisms, especially fungi, despite their ecological and economic significance. Based on previous research, we define and test a series of hypotheses regarding the composition of fungal communities, their most influential drivers and their spatial scale dependence.LocationCzech Republic.Time periodPresent.Taxa studiedFungi.MethodsWe analysed the distance decay relationships, community composition and its drivers (physical distance, litter and soil chemistry, tree composition and climate) in fungi using multivariate analyses. We compared the results across three fungal ecological guilds (ectomycorrhizal fungi, saprotrophs and yeasts), two forest microhabitats (litter and bulk soil) and six spatial scales (from 5 m to 80 km) that comprehensively cover the Czech Republic.ResultsWe found that, similar to macroorganisms, the ectomycorrhizal fungi and saprotrophs showed marked distance–decay relationships, and their community composition was driven mainly by vegetation and dispersal at local scales but, at regional scales, by environmental effects. In contrast, the third fungal guild, the unicellular yeasts, showed little distance decay, suggesting extraordinary spatial homogeneity, as often seen in microorganisms, such as bacteria.Main conclusionsOur results underscore the remarkable variation in the community ecology of fungi, which seems to range well‐known patterns both from the macro‐ and the microworld. Knowledge of these patterns advances our understanding of the ecology of fungi, rather understudied organisms of significant ecological and economic importance, which our findings identify as a potentially suitable model for bridging the gaps between the biogeography of micro‐ and macroorganisms.

“…There appears to be a general consensus that N deposition increases soil C sequestration due to the decline in SOM decomposition via the reduction of fungal abundance and decomposer activity in many different soil environments, including temperate and boreal forests ( Frey et al 2014 , Maaroufi et al 2015 ). Since, similar to plants, many fungi respond to P availability in soil and it is an important driver of fungal abundance in soils without N limitations ( Odriozola et al 2021 ), increased N content may act on fungal productivity and community composition indirectly through P limitation ( Fig. 1 ).…”

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.
