Summary: The global increase in nitrogen deposition onto forests, primarily due to fertilizer production and fossil fuel burning, is expected to double by 2050. This study focused on the influence of increased nitrogen deposition on leaf-associated fungal and bacterial communities in a temperate forest, highlighting changes in diversity without affecting leaf nutrient contents. The results suggest a specific response to altered nitrogen inputs in the bacterial and fungal communities, with an increase in symbiotrophic fungi in nitrogen-treated samples.

Summary: This study investigates the factors affecting the fine-root decomposition rate of tree species with different mycorrhizal associations and finds that arbuscular mycorrhizal (AM) trees have faster decomposition rates than ectomycorrhizal (ECM) trees in temperate forests, while there is no significant difference in (sub)tropical forests. Additionally, root chemistry and climate play important roles in determining the fine-root decomposition rate.

Summary: This study found that root exudates from purple moor grass significantly inhibited the growth of sessile oak, while the oak root exudates favored oak growth without affecting the moor grass. Resource exploitation had a greater impact on oak growth than allelopathy, with both processes leading to a 50% decrease in oak biomass.

Summary: The Janzen-Connell hypothesis has been studied by many ecologists in various forests, with research suggesting that mycorrhizal type and fungal composition may impact conspecific negative density dependence among tree species. This study found that AM tree species experienced stronger CNDD compared to EM tree species, and that trees with higher mutualistic fungi and lower pathogenic fungi may suffer lower CNDD. The findings highlight the important role of mycorrhizal association in mediating the strength of CNDD on tree survival in temperate forests.

Summary: Our study investigates how different mycorrhizal associations of temperate hardwood trees (i.e., arbuscular (AM) versus ectomycorrhizal (ECM) associations) influence soil fungal communities by altering the diversity and abundance of saprotrophic and plant-pathogenic fungi along natural gradients of mycorrhizal dominance. As temperate hardwood forests are predicted to become more AM dominant with climate change, examining soil communities along mycorrhizal gradients is crucial to understand how these global changes may affect future soil fungal communities and their functional potential. Our study, along with recent research, identifies possible global trends in the frequency of specific fungal functional groups responsible for nutrient cycling and plant-soil interactions in relation to mycorrhizal associations.

Summary: The oak species in eastern North America are declining in abundance, and whether or not they are drought tolerant depends on the metric of success. While oak trees sometimes have an advantage in gas exchange and growth, their vulnerability to hydraulic failure makes them just as or more likely to perish during drought than neighboring species.

Summary: This study investigated how soil acidity mediates nutrient cycling in forests dominated by arbuscular mycorrhizal (AM) trees and ectomycorrhizal (ECM) trees. The results showed that ECM-dominated forests were associated with greater soil acidity, reflecting differences in soil acid-base chemistry induced by mycorrhizal associations. These findings suggest that feedbacks between plant nutrient-use strategies and soil properties can impact forest community assembly and ecosystem processes on a global scale.

Summary: First principles predict that there is a relationship between plant and mycorrhizal fungal diversity, but this relationship is inconsistent on larger scales, likely due to different relationships between different mycorrhizal fungal guilds and plant diversity, scale dependency, and lack of coordinated sampling efforts. Understanding the coupling between plant and mycorrhizal fungal diversity across scales is important for predicting the ecosystem consequences of species gains and losses.

Summary: Most Earth system models do not consider the carbon costs of plant nutrient acquisition, leading to uncertainty in predicting land carbon sinks. This study integrates a model that simulates nitrogen and phosphorus acquisition by plants, showing that 80% of land is co-limited by nitrogen and phosphorus. The new model predicts that plants globally invest significant carbon to acquire nitrogen and phosphorus, resulting in a decrease in global net primary production.

Summary: Past industrial activities have caused soil contamination and volatilization of Mercury (Hg). Current phytomanagement techniques aim to stabilize Hg in soil, but the interaction between dead fungal residues and soil Hg is not well understood. This study found that fungal necromass can passively accumulate substantial amounts of Hg in soil and lipid compounds play a role in Hg biosorption. These findings suggest that fungal necromass may be an important factor in immobilizing Hg in soil.

Summary: With the global decline of old trees and reforestation efforts, younger trees are becoming increasingly important for carbon sequestration and forest ecosystem functioning. This study finds that younger trees in the upper canopy layer are more sensitive to drought and experience larger growth reductions. However, they also recover more quickly from drought, suggesting a potential positive impact on carbon stocks over time.

Summary: Dominant tree mycorrhizal associations with the environment play a significant role in shaping belowground microbial communities and nutrient cycling. The interaction between mycorrhizal types and site location explains more variation in fungal community composition, richness, and function than specific soil properties. The relative abundance of plant pathogens is particularly responsive to tree mycorrhizal dominance, with increased presence around arbuscular mycorrhizal (AM) trees compared to ectomycorrhizal (ECM) trees.

Summary: This study provides a unique investigation of NOy fluxes on a landscape scale, considering land-use types, human influence, and seasonality, to determine large-scale heterogeneity and provide a basis for future modeling and hypothesis generation. The study finds significant differences in functional potential and activity of nitrifying and denitrifying soil microbes linked to NOy emissions, and suggests that human influence is a more significant effector of soil NOy emissions than land-use type.
