“…The primary drivers of the EcM fungi community at different scales are not necessarily the same (Peay and Matheny, 2016). EcM fungi were strongly determined by the soil environment, and the edaphic factors are approved to be the major drivers of the EcM fungal community at a local scale (Miyamoto et al, 2015).…”

Pinus sylvestris var. mongolica (P. sylvestris) is a pioneer afforestation species for wind and sand fixation in northern China. However, most plantations have undergone unprecedented degradation since the early 1990s. Ectomycorrhizal (EcM) fungi are expected to be substantially related to the degradation of P. sylvestris plantations; however, the direct evidence for this remains unclear. For this purpose, we investigated variation among EcM fungal communities associated with P. sylvestris root samples of three age groups (half-mature, near-mature, and mature) in Mu Us Desert. Our results found a total of 72 EcM fungal operational taxonomic unit (OTU) belonging to Basidiomycota (63) and Ascomycota (9). The EcM fungal community is highly enriched in Rhizopogon, Tuber, Tomentella, and Inocybe, and the variations of their abundance mainly contribute to community differences. The diversity index and fungal species richness showed increasing trends toward the mature forest but did not reach a significant level (p > 0.05). The main factors that affected the dominant EcM fungal community were URE, INV, and SOC, but for the whole EcM fungal community, the effects of soil environments with plantation aging are not significant (p > 0.05). Understanding the effects of environmental factors on the structuring of the EcM fungal communities is critical to sustainable forest management in the future.

“…Linked climate-ECM community models suggest large-scale taxonomic and morphological variability at the regional and continental scale (Steidinger et al, 2018); plausibly, this variability suggests that widely distributed ECM communities may not be functionally equivalent (but see Talbot et al, 2014). Research spanning a variety of spatial scales is recommended to uncover the environmental constraints governing the distribution of ECM fungi (Peay & Matheny, 2016), and their ability to decay SOM and transfer N to their plant host. A possible by-product of such studies is the direct refinement of the role of ECM fungi in SOM dynamics across a range of scales and biomes.…”

Summary The extent to which ectomycorrhizal (ECM) fungi enable plants to access organic nitrogen (N) bound in soil organic matter (SOM) and transfer this growth‐limiting nutrient to their plant host, has important implications for our understanding of plant–fungal interactions, and the cycling and storage of carbon (C) and N in terrestrial ecosystems. Empirical evidence currently supports a range of perspectives, suggesting that ECM vary in their ability to provide their host with N bound in SOM, and that this capacity can both positively and negatively influence soil C storage. To help resolve the multiplicity of observations, we gathered a group of researchers to explore the role of ECM fungi in soil C dynamics, and propose new directions that hold promise to resolve competing hypotheses and contrasting observations. In this Viewpoint, we summarize these deliberations and identify areas of inquiry that hold promise for increasing our understanding of these fundamental and widespread plant symbionts and their role in ecosystem‐level biogeochemistry.

“…The fruiting bodies of these species, being small and adhering to the soil or the underside of woody debris, are likely to be inefficient for long distance dispersal, resulting in strong spatial patterns driven by dispersal limitation (Rosenthal et al, 2017). For Russulales, it has been shown that they could have a tropical origin (Hackel et al, 2022), which could result in many Russulales being more strongly structured along a climatic gradient and limited by low temperatures than other clades of ECM fungi that evolved mostly in temperate or boreal regions (Peay and Matheny, 2016). The absence of ecoregional structure for the other orders suggest, that species within these orders do not exhibit strong ecoregion preference.…”

Aim: Ecoregions and the distance decay in community similarity are fundamental concepts in biogeography and conservation biology that are well supported across plants and animals, but not fungi. Here we test the relevance of these concepts for ectomycorrhizal (ECM) fungi in temperate and boreal regions. Location: Europe. Time period: 2008 - 2015. Major taxa studied: Ectomycorrhizal fungi. Methods: We used a large dataset of ~ 24,000 ectomycorrhizas, assigned to 1,350 operational taxonomic units, collected from 129 forest plots via a standardised protocol. We investigated the relevance of ecoregion delimitations for ECM fungi through complementary methodological approaches based on distance decay models, multivariate analyses, and indicator species analyses. We then evaluated the effects of host tree and climate on the observed biogeographical distributions. Results: Ecoregions predict large-scale ECM fungal biodiversity patterns. This is partly explained by climate differences between ecoregions but independent from host tree distribution. Basidiomycetes in the orders Russulales and Atheliales and producing epigeous fruiting bodies, with potentially short-distance dispersal, show the best agreement with ecoregion boundaries. Host tree distribution and fungal abundance (as opposed to presence/absence only) are important to uncover biogeographical patterns in mycorrhizas. Main conclusions. Ecoregions are useful units to investigate eco-evolutionary processes in mycorrhizal fungal communities and for conservation decision-making that includes fungi.
