Abstract Plant nutrient stoichiometry is of critical importance to productivity and cycling in terrestrial ecosystems. The impacts tree species diversity on have been well studied at the stand level.

We randomly selected eight from a large‐scale biodiversity experiment with mixtures up 32 subtropical China assess effects richness, phylogenetic trait dissimilarities competition focal associated either arbuscular (AM) or ectomycorrhizal (EM) fungi. further investigated whether alter growth by regulating C:N:P stoichiometry. Neighbourhood richness had no significant C:N, N:P C:P for both AM EM trees. Increased dissimilarity significantly decreased but did not affect those species. Foliar increasing neighbour (specific leaf area, root diameter, wood density dissimilarity, total trait) dissimilarities, while increased remained unchanged. increase index resulted an C:N structural equation model analysis revealed that functional indirectly enhanced decreasing C:N. Conversely, neighbourhood‐specific length reduced N:P. Synthesis .

Abstract Soil enzymes are crucial in mediating ecosystems' responses to environmental drivers, so that the comprehension of their sensitivity drivers global change can help make predictions future scenarios and design tailored interventions biomanipulation. Drivers usually act combination two or more, indirect effects one driver acting through modification another often occur, yet most both manipulative meta‐analysis studies available tend focus on direct effect single activity specific soil enzymes. One biggest challenges is, therefore, represented by difficulty assessing interactions between different due complexity disentangling from combined ones. In this review, after elucidating general mechanisms enzyme production regulation, we display state‐of‐the‐art knowledge direct, main activities, identify gaps research, plus analyse how reverberate biomanipulation techniques for improvement ecosystem services. We conclude qualitative but not quantitative outcomes be predicted some such as warming + drought CO 2 , while other ones, results controversial: basic research will have center holistic approach.

Summary Bark serves crucial roles in safeguarding trees physically and chemically, while also contributing to nutrient cycling carbon sequestration. Despite its importance, the broader biogeographical patterns potential factors influencing bark C : N P stoichiometry forest ecosystems remain largely unknown. In this study, we compiled a comprehensive dataset comprising (C), nitrogen (N), phosphorus (P) concentrations with 1240 records from 550 diverse sites systematically analyze large‐scale controlling stoichiometry. The geometric means of C, N, were found be 493.17 ± 1.75, 3.91 0.09, 0.2 0.01 mg g −1 , respectively. Correspondingly, P, mass ratios 135.51 8.11, 3313.19 210.16, 19.16 0.6, exhibited conspicuous latitudinal trends, exception ratios. These primarily shaped by significant impacts climate, soil conditions, plant functional groups.

Abstract Global patterns of leaf nitrogen (N) and phosphorus (P) stoichiometry have been interpreted as reflecting phenotypic plasticity in response to the environment, or an overriding effect distribution species growing their biogeochemical niches.

In contrast, evergreen broadleaves conifers generally showed no significant trend.

ABSTRACT Human activities are altering terrestrial ecosystem biogeochemistry globally by augmenting the availability of multiple biologically essential nutrients, thereby potentially plant internal concentrations (i.e., stoichiometry) across a diverse array elements.

Abstract Screening species-rich communities for the variation in functional traits along environmental gradients may help understanding abiotic drivers of plant performance a mechanistic way. We investigated tree leaf trait an elevation gradient (1000–3000 m) highly diverse neotropical montane forests to test hypothesis that elevational change reflects trend toward more conservative resource use strategies at higher elevations, with interspecific decreasing and integration increasing due filtering. Analysis variance partitioning across 52 species revealed most dominant influence phylogeny, except SLA, thickness foliar Ca, where was influential.
