Abstract Trees interact with a multitude of microbes through their roots and root symbionts such as mycorrhizal fungi endophytes. Here, we explore the role fungal predictors soil root-associated microbiomes widespread broad-leaved trees across European latitudinal gradient. Our results suggest that, alongside factors climate, soil, vegetation properties, colonization by ectomycorrhizal, arbuscular mycorrhizal, dark septate endophytic also shapes tree-associated microbiomes. Notably, structure our sites is more strongly consistently associated endophyte than many abiotic factors. Root endophytes has consistent negative association relative abundance diversity nutrient cycling genes. study not only indicates that root-symbiotic interactions are an important factor structuring communities functions in forest ecosystems, but hitherto less studied likely to be central players these interactions.

Forests have a key role in mitigating both non-biological and biological ecological disturbances. However, major disturbances (soil pollution, shift from native forest species to exoticones, forested watersheds climate changes) can different impacts on forest’s soil microbiome. Because the microbial community of forests has variety ecosystem services that promote health, this review tries answer following questions: (i) Which are main drive responses microbiome? (ii) How we measure these changes? For aim, summarizes details tree vegetation type, communities ecosystems, mutual influence between plants, soil, microbiomes. Microbial shaped by factors such as type composition, plant types, nutrient levels fertility, disturbance patterns, symbiotic associations, biotic interactions, progression succession. Anthropogenic activities produce rapid response communities, leading short- long-term alterations. Harvesting processes reduce drastically microbiome diversity, forcing specialized more generalist microorganisms. Restoration scenarios indicate re-establishment level similar forest, but with high percentage replaced This emphasizes is range environmental, ecological, factors. The primary drivers ecosystems discussed include composition availability, structure, interactions within disturbances, succession, temporal dynamics.

Distinct effects of host and neighbour tree identity on arbuscular and ectomycorrhizal fungi along a tree diversity gradient

ISME Communications, Journal Year: 2021, Volume and Issue: 1(1)

Published: Aug. 20, 2021

Plant diversity and plant-related ecosystem functions have been important in biodiversity-ecosystem functioning studies. However, biotic interactions with mycorrhizal fungi understudied although they are crucial for plant-resource acquisition. Here, we investigated the effects of tree species richness type on arbuscular (AMF) ectomycorrhizal fungal (EMF) communities. We aimed to understand how dissimilarities taxa composition beta-diversity related target trees neighbours same or different type. sampled a experiment saplings (~7 years old), where (monocultures, 2-species, 4-species mixtures) were manipulated. AMF EMF significantly increased increasing richness. mixture plots resembled that sum respective monocultures, whereas was lower compared monocultures.

Abiotic and biotic drivers of tree trait effects on soil microbial biomass and soil carbon concentration

Ecological Monographs, Journal Year: 2022, Volume and Issue: 93(2)

Abstract Forests are ecosystems critical to understanding the global carbon budget, due their sequestration potential in both aboveground and belowground compartments, especially species‐rich forests. Soil is strongly linked soil microbial communities, this link mediated by tree community, likely modifications of microenvironmental conditions (i.e., biotic conditions, properties, microclimate). We studied concentration biomass 180 local neighborhoods along a gradient species richness ranging from 1 16 per plot Chinese subtropical forest experiment (BEF‐China). Tree productivity different functional traits were measured at neighborhood level. tested effects productivity, trait identity, dissimilarity on concentrations, mediation conditions. Our analyses showed strong positive correlation between concentrations. In addition, increased with root diameter, while it decreased litterfall C:N content.

Understanding the complex interactions between trees and fungi is crucial for forest ecosystem management, yet influence of tree mycorrhizal types, species identity, diversity on tree-tree their root-associated fungal communities remains poorly understood. Our study addresses this gap by investigating different arbuscular (AM) ectomycorrhizal (EcM) pairs (TSPs) in a subtropical experiment, spanning monospecific, two-species, multi-species mixtures, utilizing Illumina sequencing ITS2 region. The reveals that type significantly impacts alpha monospecific stands. Meanwhile, identity's modulated overall diversity. Tree-related variables spatial distance emerged as major drivers variations community composition. Notably, compositional differences root AM EcM diminish, indicating convergence irrespective type. Interestingly, dual were observed these mixtures.
