Summary: This study found that host identity is a key factor in determining the composition of ectomycorrhizal (ECM) fungal communities in exotic pine trees during early establishment, with native pines associating with Rhizopogon while exotic pines primarily associated with ECM generalists. However, after 6 months, both native and exotic pine trees exhibited ECM fungal communities dominated by Rhizopogon species. The selection of pioneer ECM fungi shared by both native and exotic pines may facilitate the establishment of exotic pine trees.

Summary: As nitrogen deposition increases, forest soils dominated by trees that associate with ectomycorrhizal fungi store more carbon compared to those dominated by trees associating with arbuscular mycorrhizae. This difference is likely due to unique nutrient cycling responses to nitrogen between the two types of mycorrhizal soils.

Summary: This study investigated the ectomycorrhizal fungal communities associated with five common pine plants in Inner Mongolia using high-throughput sequencing, revealing significant impacts of host plant phylogeny, soil, climate, and spatial distance on fungal diversity and community composition. Stochastic processes were found to predominantly determine the community assembly of ectomycorrhizal fungi, with strong preferences observed between plant species and fungal operational taxonomic units.

Summary: This study aimed to explore successful establishment methods for introducing exotic Pinus radiata trees. The results showed that P. radiata could establish in a new habitat either with or without the co-introduced Lactarius deliciosus. The co-introduced L. deliciosus may become naturalized in the new area. The introduction of L. deliciosus significantly altered the fungal community composition and had a positive correlation with nutrient acquisition of P. radiata. Host identity had no significant effect on fungal composition.

Summary: This study found that feces of non-native wild boar, brown hare, and native pampa fox could effectively inoculate ectomycorrhizal pine seedlings. Molecular analyses revealed that the exotic ectomycorrhizal fungi consumed by non-native wild boar and brown hare, Suillus granulatus and Rhizopogon pseudoroseolus, were successfully forming ectomycorrhizas with pine roots. This provides novel evidence for the long-distance dispersal of exotic ectomycorrhizal fungi by non-native and native animal vectors.

Summary: This study reveals the relationship between Pinus cembra and ectomycorrhizal fungal communities under natural conditions, and finds that geographic region and slope exposure play a significant role in the composition of ectomycorrhizal fungal communities.

Summary: The study found that the nitrogen uptake patterns of understory trees vary between different overstory trees, possibly due to differences in soil mycorrhizal community and nitrogen availability. Understory trees beneath non-ECM overstory trees primarily absorbed nitrogen as nitrate, while those beneath ECM overstory trees relied on mycorrhizal fungi for nitrogen acquisition. Leaf nitrogen concentrations were lower in understory trees beneath ECM compared to non-ECM overstory trees.

Summary: This study aimed to investigate the impact of climate on the community composition and structure of ectomycorrhizal (EM) fungi in Mongolian pine plantations at different stand ages. It was found that the richness and community composition of EM fungi were not significantly different with stand aging. However, the growing stage had a greater influence on the beta diversity of the EM fungal community, which was closely related to seasonal climate, particularly precipitation.

Summary: This study investigated the effects of climate and host phenology on the community composition and structure of ectomycorrhizal (EM) fungi in Mongolian pine plantations. The results showed that seasonal climate, particularly precipitation, had a greater impact on the beta diversity of the EM fungal community than stand age. This information can be used as a theoretical basis for the reforestation and rehabilitation of Mongolian pine plantations using mycorrhizal techniques.

Summary: Cenococcum geophilum shows a high tolerance to fenitrothion, which may explain its dominance over other ectomycorrhizal species in coastal forests in Japan where the insecticide is routinely sprayed. The growth of all three ectomycorrhizal fungi, including C. geophilum, Rhizopogon roseolus, and Pisolithus arhizus, decreased significantly with increasing fenitrothion dosage.

Summary: Positive interactions between non-native species can accelerate invasion rate and exacerbate impacts. Contrary to expectations, invasive ectomycorrhizal fungi (EMF) were found even in sites without invasive mammals. Alternative mechanisms, such as saltation, bird dispersal, or human dispersal, may contribute to the arrival of EMF in native stands.

Summary: This study characterized the ectomycorrhizal fungi (ECMF) associated with whitebark pine (WBP) in the Columbia Mountains of Interior British Columbia, Canada. The results identified several ECMF species and genera and revealed their correlation with tree health and seedling survival. The findings highlight the importance of understanding the ecology of WBP ECMF and their impact on tree performance in WBP recovery efforts.

Summary: The study revealed that the composition of ectomycorrhizal fungal communities varies within Scotland at both large and small scales, but genetic variation in constitutive defensive compounds does not determine the composition of ectomycorrhizal communities among closely cohabiting pine seedlings. Patchy distributions of ectomycorrhizal fungi at small scales may prevent genetic variation in associations with different species from being realized under field conditions. The case for selection on traits mediating associations with specific fungal species may be overstated, at least in seedlings.

Summary: This study investigated the relationship between Pinus massoniana genotype and ectomycorrhizal (ECM) fungal communities by examining ECM fungal communities, soil nutrients, extracellular enzyme activity, and leaf nutrient concentrations in families with different growth levels. The results showed that the high-growth (HG) family had more diverse ECM fungal communities compared to the medium-growth (MG) and low-growth (LG) families. Amphinema was the main contributor to the differences among the families and positively affected the growth of the HG family and the accumulation of soil organic carbon.

Summary: The study revealed that high-severity wildfires led to lower ectomycorrhizal and saprobic fungal richness, significantly altering fungal communities in fire-adapted ecosystems by selecting resilient species and initiating post-fire succession. Fire-driven changes in soil environment influenced fungal richness and community composition, indicating long-term impacts of wildfires on soil fungal dynamics.
