Summary: This study analyzed the stoichiometric characteristics of C, N, and P in a karst primary forest plant community in China. The results showed that N and P content in leaves was higher than that in branches, while C content in branches was higher than in leaves. Leaf stoichiometry was strongly influenced by species diversity, while branch stoichiometry was mainly influenced by leaf and species diversity, as well as environmental factors such as altitude, soil pH, and total soil P.

Summary: Understanding the contents and stoichiometry of carbon, nitrogen, and phosphorus in a forest ecosystem is crucial for evaluating its function and processes. This study investigated the spatial and temporal distribution of C, N, and P contents and their stoichiometry in Shennongjia Forest. The results showed that TOC and TN contents decreased with soil depth, while TP contents remained relatively stable. The C:P, C:N, and N:P ratios varied among different components of the ecosystem. Altitude had a significant effect on the contents of TOC, TN, and TP in soil, but not in litterfall and humus. Moisture content, vegetation pattern, bulk density, tMn, tFe, and clay content were identified as important driving factors for the contents of TOC, TN, and TP in soil. This study provides valuable data for forest management and ecosystem optimization.

Summary: Diazotrophs play a key role in nitrogen cycling in tropical/subtropical forests, but little is known about the dynamics of diazotroph communities during forest succession. The study found that diazotrophic diversity increased with forest succession in one chronosequence, while relative abundance of the dominant genus Bradyrhizobium was influenced by soil phosphorus concentration. Soil phosphorus availability was identified as a crucial factor in mediating diazotroph community composition during forest succession in subtropical forests.

Summary: This study conducted a field experiment to investigate the effects of over-canopy and understory nitrogen addition on nitrogen budgets in a lower subtropical monsoon evergreen broadleaved forest. The results showed that the forest was not saturated with nitrogen after receiving additional nitrogen for 6 years. Plants were able to absorb the added nitrogen by increasing the nitrogen concentrations in their organs. The study also highlighted that understory nitrogen addition may underestimate the effects of nitrogen deposition in forests.

Summary: The study found that nitrogen addition significantly increased soil N2O emissions due to elevated NH4+-N content, while phosphorus addition had a minor impact on N2O emissions. Interactive N and P additions slightly stimulated N2O emissions. High-dose phosphorus addition significantly increased soil CH4 uptake, while nitrogen and low phosphorus additions did not have a significant effect on CH4 uptake.

Summary: Changes in altitude have significant effects on mountain forest ecosystems. This study investigated the changes in soil carbon, nitrogen, and phosphorus contents along an altitudinal gradient in subtropical karst mountain forests in Southwest China. The results showed that the contents of organic carbon, total nitrogen, and available nitrogen in soil initially increased and then decreased with altitude, while the contents of total phosphorus and available phosphorus showed no significant trend. Various factors, such as total glomalin-related soil protein and soil moisture content, influenced the soil nutrient contents at different soil depths. These findings have implications for the sustainable management of subtropical mountain forests.

Summary: This study measured leaf nitrogen content of 1,844 plant species from 22 natural communities and investigated the effect of different scaling-up methods on the spatial variation of leaf nitrogen in plant communities. The results showed that different scaling-up methods influenced the spatial variation of leaf nitrogen, with N-SAM and N-CWM decreasing with increasing precipitation, and NPLA-CWM showing the opposite trend. Additionally, N-SAM overestimated leaf nitrogen in dry or cold environments and underestimated it in wet or warm environments compared to N-CWM.

Summary: This study explored the strategies of arbuscular mycorrhizal (AM) and ectomycorrhizal (EM) tree species in acquiring phosphorus (P) nutrients in subtropical forests. The results showed that AM trees absorbed more P from the soil while EM trees resorbed more aboveground P. Structural equation modeling revealed that AM trees were dominated by bacteria, resulting in lower pH, while EM trees were dominated by ectomycorrhizal and saprophytic fungi that secreted acid phosphomonoesterase to mine P in the rhizosphere soil. AM trees had higher mycorrhizal colonisation rates while EM trees had higher specific root lengths, indicating different dependence on mycorrhizae and roots in scavenging P from the soil.

Summary: Water availability has a significant impact on climate-vegetation interactions in drylands. Precipitation has a larger influence on vegetation dynamics than temperature, with stronger associations in the Southern Hemisphere than the Northern Hemisphere. Moderate soil moisture enhances the associations between precipitation and vegetation dynamics, but not for temperature-vegetation associations. Over the past three decades, increased soil moisture has led to a decrease in precipitation-vegetation associations, indicating a consistent pattern in water-limited ecosystems.

Summary: With the rapid accumulation of plant trait data, there are major opportunities to integrate these data into predicting ecosystem primary productivity across different spatial extents. However, scaling up to the ecosystem scale has remained challenging. This study demonstrates the need to combine community-level traits and environmental factors to predict ecosystem productivity at landscape or biogeographic scales, and highlights the potential for integrating traits into ecological models to estimate productivity-related ecosystem functions and anticipate the response of terrestrial ecosystems to global change.

Summary: Home-field advantage (HFA) refers to the faster decomposition of litter in home soil compared to away soil due to the specialization of decomposer organisms. Previous research on HFA has mainly focused on aboveground litter, neglecting the role of roots. Labile carbon input from root exudates can enhance microbial activity, leading to the breakdown of older root litter. However, the effects of fresh root-derived inputs on HFA and the decomposition of different types of roots remain unclear.

Summary: Plants allocate nutrients to new leaves by balancing the absorption in the roots with resorption in the leaves. This trade-off may also affect leaf litter decomposition. The study provides empirical evidence for a continuum of nutrient-associated processes, which is linked to the leaf economics spectrum and mycorrhizal association.

Summary: The Grain-for-Green Program in China aims to restore severely degraded sloping karst cropland to secondary forest. This study investigated the responses of carbon release from soils (heterotrophic respiration, Rh) during the natural vegetative recovery process. The results showed that vegetation restoration significantly increased Rh rates, but reduced in the later stages of recovery and primary forest. Soil physicochemical properties and microbial properties explained a portion of the variations in Rh, with nitrogen to phosphorus stoichiometry having the most direct and positive effects. Managing soil nutrient status and microbial biomass are important for regulating carbon decomposition in karst soils.

Summary: This study explored the responses of leaves and absorptive roots to nutrient deposition in Pinus massoniana and Schima superba forests in subtropical China. It found that nitrogen deposition had persistent negative effects on root decomposition, phosphorus deposition had a positive effect on leaf decomposition, and nitrogen-phosphorus deposition had a positive effect on leaf decomposition in the late stage. The study also found that the decomposition rates were correlated with acid phosphatase activity, indicating a microbial mechanism.
