Article Abstract
The nutrient ecological stoichiometry of plants and soil is important for the growth and dynamics of species, but the stoichiometric relationships among leaf, litter, and soil remain poorly understood. We analyzed the carbon (C), nitrogen (N), and phosphorus (P) stoichiometry of the leaves, litter, and soil for 31 species at 140 sites in warm temperate forests in northwestern China to document the patterns of nutrient traits and their relationships with climatic factors. The average concentrations of C, N, and P in the combined forests were 462.97, 18.04, and 1.32 g kg for leaves, 365.12, 12.34, and 0.87 g kg for litter, and 15.72, 1.29, and 0.54 g kg for soil, respectively. The concentrations differed significantly among the leaves, litter, and soil. Leaf and soil nutrients were not significantly correlated, whereas leaf and litter nutrients and litter and soil nutrients were significantly correlated, indicating that litter provided a link between leaves and soil and demonstrating the nutrient associations among leaves, litter, and soil. Soil nutrients were strongly correlated with climatic factors, and precipitation had a larger impact than temperature on the plants and soil. This study will help to predict the growth and dynamics of species under environmental changes.

Beech leaf disease (BLD) poses a serious threat to the health of beech forests throughout the northeastern USA and Canada. Caused by invasive nematodes, BLD first appeared in 2012 in Ohio and has rapidly spread eastward. We investigated the effects of BLD on leaf and litter chemistry and leaf litter decomposition rate from four infected beech stands in Falmouth, Massachusetts.

Introduction: Peatlands store up to a third of global soil carbon, and in high latitudes their litter inputs are increasing and changing in composition under climate change. Although litter significantly influences peatland carbon and nutrient dynamics by changing the overall lability of peatland organic matter, the physicochemical mechanisms of this impact-and thus its full scope-remain poorly understood.
Methods: We applied multimodal metabolomics (UPLC-HRMS, H NMR) paired with C Stable Isotope-Assisted Metabolomics (SIAM) to track litter carbon and its potential priming effects on both existing soil organic matter and carbon gas emissions.

Thinning is a crucial silvicultural practice in forest management, the rational intensity of which plays an important role in increasing carbon sequestration capacity of forest ecosystems. However, it is not clear how different thinning intensities affect forest ecosystem carbon stocks and their fractions. We investigated plantations in the mountainous regions of eastern Liaoning Province, analyzed changes in carbon stocks and fractions with different thinning intensities (0, 10%-30%, 30%-50% and 50%-70%), and explored key factors influencing stand productivity and soil organic carbon dynamics.

Soils are a major reservoir for organic carbon (C), with subsoils (> 20-30 cm soil depth) storing most of this C. Predicting the response of deep-soil C to global change remains a critical research priority; yet long-term field observations for forests are scarce. In this study, we assessed decadal C dynamics in mineral soils to 90 cm depth of 62 temperate mature stands of European beech (Fagus sylvatica) in Austria using data from sampling campaigns in 1984, 2012, and 2022.

Phosphorus components in the soil aggregates of different particle sizes is critical for improving phosphorus availability in north subtropical regions. We investigated two representative stand types, pure stands and the mixed stands of and in Lishui District, Nanjing. We measured soil aggregates from two soil layers (0-20 cm and 20-40 cm) to determine the stability of soil aggregates, labile phosphorus fraction content and the acid phosphatase activity of each particle size, as well as litter biomass and fine root biomass, to analyze the differences of active phosphorus fractions of soil aggregates between different stand types.
