Summary: Mixed forest stands exhibit greater drought resistance compared to single-species stands due to complementarity in root ecology and physiology. This study investigates whether differences in the drought resistance of soil microbiomes contribute to this phenomenon. The results indicate that changes in soil moisture primarily affect bacteria, particularly Rhizobiales, while fungi, including ectomycorrhizal fungi, are generally unaffected. The resistance of the soil microbiome is higher in spruce root zones compared to beech root zones, corresponding to the proportions of drought-tolerant and drought-sensitive bacterial taxa. Mixed-species root zones contain a hybrid microbiome associated with both beech and spruce. The relative abundances of soil bacteria closely track moisture gradients and are more predictive of soil water content than other environmental variables.

Summary: This study revealed that tree species composition and soil properties have significant impacts on soil fungi, with fungal communities being influenced by soil properties and tree species composition. Mixed forests generally exhibit higher fungal diversity compared to mono-specific forests, suggesting that the response of fungal guilds and taxa to forest types and soil properties can potentially influence nutrient fluxes.

Summary: The presence of auxins was found to stimulate native proteolytic activity, while cytokinins, ethephon, and chlorocholine chloride inhibited it. These negative phytohormonal effects may slow down organic matter decomposition rates and complicate plant nutrition. This study enhances understanding of the effects of rhizosphere exudates on soil microbial activity and the nitrogen cycle.

Summary: Climate change leads to habitat loss and biodiversity decline of conifer tree species. We developed a new approach that combines soil variables with climate niche model and considers interspecific competition to predict the impacts of climate change on tree species. Our study on the endangered conifer species - Chamaecyparis formosensis - showed that its suitable habitat will significantly decrease in the future with an additional threat from oak tree competition. Our approach and findings have important implications for conservation strategies, assessing climate change impacts, and refining ecological niche models.

Summary: This study found that different tree species in mixed beech forests have varying effects on soil functions. Some tree species can enhance soil microbial biomass carbon, while others accelerate litter decomposition and enhance biotic activities and carbon/nitrogen dynamics. In old-growth beech forests, Alnus subcordata, Carpinus betulus, and Fraxinus excelsior are the main drivers of microbial activities related to nutrient cycling.

Summary: Temperate forest soils act as sources of CO2 and sinks for CH4, the two main greenhouse gases responsible for climate change. The fluxes of CO2 and CH4 are influenced by tree species identity and diversity, with deciduous trees showing higher fluxes. Soil CO2 fluxes are more influenced by tree species than CH4 fluxes. Total litter inputs, temperature, soil carbon to nitrogen ratio, soil moisture, and organic horizon depth are important factors affecting soil carbon fluxes.

Summary: Soil aggregate stability is an important factor for soil structure, quality and erosion. This study focused on how the inclusion of broadleaf tree species affects soil aggregate stability in Chinese fir plantations. The results showed that mixed stands of Chinese fir with broadleaf trees had higher soil chemical properties and more stable soil structure, especially when mixed with Michelia macclurei and Mytilaria laosensis. Soil organic carbon and nitrogen contents were positively correlated with soil aggregate stability, while soil erodibility had a negative correlation.

Summary: There is a lack of studies on mixed-species forests during regeneration phases, especially for species like Pinus pinaster and Pinus halepensis in Mediterranean ecosystems. This study investigates the interactions of these species at different tree densities during the first years of establishment. Pinus halepensis showed higher survival rates and basal diameter increments, while Pinus pinaster's response to density and mixture needs further research. Competitive and facilitating seedling interactions were observed at higher densities, promoting seedling survival but decreasing early growth.

Summary: Quercus robur/Quercus petraea and Pinus sylvestris are economically important tree species in Europe, and their growth can be affected by climate, competition, and mixture. This study investigated the diameter growth of these species in monospecific and mixed stands along an ecological gradient. The final model explained 87% of the total variation in diameter increment, with significant effects of age, climate variables, local competition, mixture, and stand structure. The results showed that tree growth declined with age and local density, but increased with social position and mixture.

Summary: Forest stand and environmental factors both affect soil organic carbon (SOC) storage, with stand factors having a stronger impact on topsoil and environmental factors having a stronger impact on subsoil. Functional diversity improves SOC storage under certain environmental conditions, but the effects differ between topsoil and subsoil. These findings suggest that the relationship between forest composition, environmental factors, and SOC storage varies across different soil depths.

Summary: Healthy soils act as a significant carbon sink on Earth, with the potential to store carbon for long periods of time. This study focuses on assessing the carbon sequestration potential of mixed and pure stands of Scots pine and beech in forest soils. The findings indicate that the percentage of species mixture primarily impacts the forest floor, while the mineral soil is mainly affected by the total organic carbon. The microsite-level scale proves to be more appropriate in studying the effects of tree stand composition on soil organic matter.

Summary: The size-related functional attributes of seedlings in Mediterranean forest species are crucial for improving the survival and performance of seedlings in dryland reforestation projects. This study evaluated the effects of nursery light regimes and nitrogen fertilization on the survival and performance of Pinus pinaster seedlings under different watering conditions. The results showed that the nursery light regime and fertilization affected the initial seedling quality and transplant stress. Watering during the first summer after planting increased seedling survival probability. The full-sunlight regime in the nursery reduced the probability of seedling mortality after planting, while the low-light regime negatively affected plant traits and increased post-planting mortality probability.

Summary: Accurate estimation of biomass is crucial for the sustainable management of forest resources, especially in the face of climate change. For Quercus suber, a joint regional model would be more beneficial due to its distribution and the nature of its biomass. However, compatibility issues proved to be a major challenge. By using dummy variables and making compromises in biomass compartments, we successfully developed two joint models to estimate aboveground biomass in Portugal, Spain, and Tunisia. We also developed a separate model for roots. All coefficients were estimated using Seemingly Unrelated Regressions (SUR) and model fitting was ensured. This work demonstrates the possibility of establishing a biologically sound and efficient model for these three countries.

Summary: The use of mobile laser scanning allows for high-resolution, 3D description of forest ecosystems. This study tested a mobile Handheld Laser Scanning (HLS) system in a structurally complex Mediterranean forest in Spain to estimate tree attributes. The HLS approach achieved a high tree detection rate and accurate estimation of diameter at breast height (DBH) and tree height. The study demonstrates the feasibility and efficiency of HLS in mapping trees in mixed forests, with potential application in forest monitoring programs.

Summary: Many studies have found that mixed species stands have higher gross growth compared to monocultures, but little is known about mortality in mixed stands. By evaluating different plots of Scots pine and European beech across Europe, this study found that mixed stands have higher mortality rates and lower net growth compared to monocultures. The study also showed that the mixing proportion of Scots pine decreased over time, indicating a tendency towards demixing due to pine.

Summary: This study used tree-ring width data and different modelling approaches to build predictive growth models and compared them to process-based models. The results showed that although there were some differences between the models, the prediction errors were small, indicating that both process-based and empirical models are effective for predicting tree growth. Furthermore, it was found that while climate factors have low sensitivity to tree growth, other factors such as tree size and soil have a significant impact.
