Special Issue Information

Dear Colleagues,

Soil microbial communities play a crucial role in forest ecosystems. In temperate and boreal forests, ectomycorrhizal symbiosis with Ascomycota and Basidiomycota fungi is an overriding symbiosis of trees. In the tropical and subtropical zones, symbioses between trees and arbuscular mycorrhizal fungi is more common. Some tree species form symbiosis with different groups of symbiotic organisms. Among them, dual mycorrhizal symbiosis between trees and both arbuscular and ectomycorrhizal fungi and tripartite symbiosis between trees, mycorrhizal fungi, and nitrogen-fixing bacteria belong to the most substantial and influential effects on the survival and growth of trees. Symbiosis with soil microorganisms is a key element of the survival of indigenous trees but also alien tree species, especially invasive ones, which generate substantial financial losses. Therefore, the ecology of symbiotic soil microbial communities in forest ecosystems is a substantial and prospective field of knowledge. This Special Issue is aimed at providing an interdisciplinary approach to soil microbial communities in forest ecosystems, with special consideration to the dual mycorrhizal symbiosis and tripartite symbiosis of trees. Potential topics include, but are not limited to:

  • Ectomycorrhizal fungal communities in forest and urban ecosystems;
  • Arbuscular symbiosis of forest tree species;
  • Functional diversity of soil microbial communities;
  • Tripartite symbiosis between plants, mycorrhizal fungi, and nitrogen-fixing bacteria;
  • Influence of alien species on the symbiotic microbiome of indigenous tree species.

Soil fungal communities play a critical role in the promotion of nutrient cycling and the stabilization of ecosystem functions in subtropical forests. Yet, clarifying the relationships between soil fungal diversity and microclimate variability along an elevational gradient, as well as understanding the driving mechanisms of their variations in subtropical forests, remains insufficiently understood. In this study, we recorded the composition and soil fungal diversity along an elevational gradient in Daiyun Mountain of China, aiming to elucidate the primary factors influencing the structure of the dominant soil fungal along an elevational gradient in subtropical forests. The results showed that (1) the dominant phylum of soil fungi at different elevations were Basidiomycota, Ascomycota (relative abundance > 10%) and Zygomycota (relative abundance > 1%). The Simpson index of soil fungi showed a clear upward trend along the elevational gradient, while no significant difference was observed in the other indices, and both overall reached their maximum value at the elevation of 1200 m. (2) The mean annual soil temperature and moisture, soil pH and available phosphorus were the main factors driving the dominant soil fungal along the elevational gradient. (3) Co–occurrence network analyses revealed a distinct modular structure of dominant soil fungal communities at different elevations, with Ascomycetes identified as the key taxa in fungi network relationships. Our research holds ecological significance in understanding the pivotal role of soil environmental factors in shaping the complex composition and interactions within soil fungal communities.
