Abstract Trait-based frameworks are promising tools to understand the functional consequences of community shifts in response environmental change. The applicability these soil microbes is limited by a lack trait data and focus on categorical traits. To address this gap for an important group microorganisms, we identify trade-offs underlying fungal economics spectrum based large collection 28 saprobic isolates, derived from common grassland grown culture plates. In dataset, ecologically relevant variation best captured three-dimensional space. primary explanatory axis represents dense-fast continuum, resembling dominant life-history other taxa. A second significant reflects mycelial flexibility, third one carbon acquisition All three axes correlate with traits involved cycling. Since stress tolerance fundamental niche gradients primarily related 2nd (carbon-use efficiency) especially 3rd (decomposition) orthogonal independent tested stressors. These findings suggest space which can now be at broader scales.

Agricultural practices significantly impact soil properties and ecological functions, highlighting the importance of comprehensive health assessments. Traditionally, these assessments have focused on physical chemical indicators, often neglecting microbiological properties. This review explores potential indicators in evaluating effects agricultural emphasizing their significance addressing challenges associated with application. A key advantage is high sensitivity rapid response to environmental changes. These can be grouped into three categories: microbial biomass abundance, taxonomic composition diversity, activity. Among these, carbon, basal respiration, decomposition rates are considered most reliable interpretable indicators. Microbial diversity remain limited diagnostic predictive capabilities due interpretation. Integrating offers a more holistic understanding interactions between health, enhancing our ability monitor, manage, preserve ecosystems. To facilitate adoption production land management, further efforts needed improve interpretability establish standardized criteria for assessment.

The interactions between sugar maple (Acer saccharum, Marshall) and its microbial communities are important for tree fitness, growth, establishment. Despite recent progress in our understanding of the rhizosphere phyllosphere maple, many outstanding knowledge gaps remain. This review delves into relationships microbes, as climate change alters plant species distributions. It highlights multifaceted roles key such arbuscular mycorrhizal (AM) fungi pathogens, affecting distribution establishment novel habitats. Furthermore, this examines how different compartments contribute to fitness. Finally, it explores dispersal altered under changing environmental conditions can affect maple's ability migrate beyond current range, emphasizing scenarios associated with shifts. In rhizosphere, AM known their nutrient acquisition improving stress tolerance. Yet, questions remain about these interact other soil chemistry alter interactions, presence beneficial microbes influences Additionally, role dark septate endophytes (DSE) fitness remains underexplored, need more research on diversity functions. phyllosphere, subject shifts due rising global change, potential impacts These changes may influence tree's resistance tolerance stress, overall health. relies mostly short-read sequencing methods targeting marker genes (e.g., 16S, ITS, 18S), which often fail identify at level. Limitations molecular techniques poor reference databases hinder fully characterize tree-associated Future should thus prioritize advanced tools shotgun, hybrid, or long-read sequencing. Controlled experiments also needed establish causal links communities, study whether throughout lifespan.
