Summary: Canopies play a crucial role in redistributing nitrogen in forest ecosystems, and not considering their influence can lead to biased estimates of the ecological consequences of human-induced nitrogen deposition. This study investigated the effects of different approaches and levels of nitrogen addition on microbial residual carbon (MRC) accumulation in a tropical forest. Results showed that the response of MRC to nitrogen addition varied with soil depth, with contrasting effects in the topsoil and subsoil. Understory nitrogen addition had greater effects on MRC accumulation compared to canopy nitrogen addition. These findings highlight the important role of canopies in mitigating the impacts of nitrogen deposition on soil carbon cycling in tropical forests and the need for further research on depth-dependent response mechanisms.

Summary: Nitrogen is an important element for plant growth and is often considered as a limiting factor in forest ecosystems. Increased nitrogen deposition has been reported to affect tree growth, but the effects are still controversial. This study investigated the effects of canopy and understory nitrogen addition on tree-ring growth and vessel traits. The results showed that both canopy and understory nitrogen addition negatively impacted tree-ring growth, with the effect of understory treatment being significant. The effects on vessel traits were inconsistent. Furthermore, nitrogen addition also affected the hydraulic architecture of the trees.

Summary: This study found that soil bacterial and fungal communities in the organic layer of a temperate forest responded differently to canopy and understory nitrogen (N) addition. Soil pH mainly regulated the response of bacterial diversity and community composition to N addition, while soil moisture and nutrient availability controlled fungal diversity and community composition. Understory N addition had a strong effect on soil bacterial Shannon diversity and community composition, but a weaker effect on soil bacterial richness in the organic soil layer.

Summary: Deposition of atmospheric nitrogen increases soil nitrous oxide emissions, and the commonly used understory nitrogen application methods underestimate the actual impacts due to overlooking nitrogen interception by forest canopies. Our study compared different nitrogen deposition simulation approaches and forms of nitrogen in a Moso bamboo forest, and found that the cumulative nitrous oxide emissions were higher in understory nitrogen application treatments compared to canopy treatments, with greater emissions under inorganic nitrogen application. Considering canopy processes is important for future studies on nitrogen deposition and soil nitrous oxide emissions.

Summary: Grasslands are experiencing increasing nitrogen fertilization, leading to changes in carbon and water cycling. Mowing has been shown to mitigate the negative impacts of nitrogen availability on species richness. However, the effects of nitrogen addition and mowing on ecosystem-level carbon fluxes and water use efficiency are still poorly understood. This study found that both nitrogen addition and mowing increased net ecosystem CO2 exchange and water use efficiency. Mowing also enhanced the positive effects of nitrogen addition on carbon fluxes and water use efficiency. Proper grassland management practices are important for improving carbon sequestration, water use efficiency, and mitigating declines in species diversity due to ecosystem eutrophication.

Summary: The increase in CO2 concentration in the atmosphere is causing metabolic and physiological changes in living beings, especially plants. This can impact crop productivity by limiting nitrogen and water uptake. The symbiosis between legumes and rhizobia can increase the biological nitrogen reserve. Elevated CO2 levels enhance nitrogen fixation primarily by increasing biomass. In this study using bean plants, inoculation with rhizobia improved nitrogen fixation and reduced oxidative stress, providing a more environmentally friendly alternative to chemical fertilization. However, further optimization of symbiotic activities is needed to improve legume yields under future climate change scenarios.

Summary: The high uncertainty associated with the response of terrestrial carbon (C) cycle to climate is dominated by the ecosystem C turnover time. The differences in climate sensitivities of turnover time in major biomass and soil pools are poorly understood, and their effects on vegetation and soil C sequestration under climate change remain unclear. This study conducted observations and model-data fusion in Chinese forests to explore the relationship between climate and turnover time. It was found that both vegetation and soil turnover time decreased with increasing temperature and precipitation, and soil turnover time was more sensitive than vegetation turnover time. The smaller balance between soil C input and exit rate under warm and humid conditions suggests a relatively lower contribution from soil C sequestration.
