Summary: This study used high-throughput sequencing to investigate the impacts of warming and nitrogen addition on soil nematode communities in a desert steppe. The results showed that warming primarily affected deep soil nematode diversity and community stability, while nitrogen addition mainly influenced surface soil nematode community. Furthermore, the interaction between warming and nitrogen addition exacerbated the negative effects on nematode richness and diversity. Soil pH was negatively correlated with NH4+ and NO3- content, and all three physicochemical parameters were significantly correlated with desert steppe soil nematode community structure. Paratylenchus, Cervidellus, and Acrobeloides were identified as the major hub soil nematode genera responding to soil warming and nitrogen addition in a desert steppe.

Summary: Anthropogenic nitrogen loading affects the abundance of soil ammonia-oxidizing archaea and bacteria, leading to changes in soil nitrification. Climate is the most important factor determining the response of the ammonia-oxidizing community to nitrogen loading, and it affects nitrification indirectly through its influence on the ammonia-oxidizing community.

Summary: The study observed the flowering phenology of a plant species in a desert steppe and found that increasing temperature was an important factor in advancing the flowering phenology. However, when high temperatures exceeded the physiological thresholds of the plants, there was a temporary delay in flowering. Additionally, the study found that the reproductive phenology was delayed from 2015 to 2018, but continued to advance after that. These findings are significant for understanding how plant species adapt to climate warming and the response mechanism of desert steppe ecosystems to climate change.

Summary: In this study, the impacts of different grazing intensity on soil microbial community diversity and composition in a long-term enclosed grazing desert steppe were examined. The results showed that 15 years of grazing significantly increased the soil organic carbon content. Microbial communities were influenced by grazing intensity and aggregate fractions, with proper grazing being identified as a key factor for maintaining the long-term sustainability of the desert steppe ecosystem.

Summary: A field experiment was conducted in the northeastern Qinghai-Tibetan Plateau to investigate the responses of soil bacterial communities in alpine steppes to nitrogen application and warming. The study found that soil bacterial diversity and community structure remained relatively stable in the short term, with warming having a significant impact on bacterial composition and rare species. The interaction between nitrogen application and warming also affected community beta-diversity, while above-ground plant variables were highly correlated with bacterial community characteristics.

Summary: In this study, nematode diversity in forest soils was found to be mainly influenced by soil organic carbon content, but climatic factors such as temperature, soil phosphorus content, soil pH, and precipitation also played significant roles. Furthermore, there were differences in nematode diversity between different climatic zones. Therefore, high-resolution studies are necessary to accurately predict the response of soil functions when climate conditions exceed the coping range of soil organisms.

Summary: Abnormally altered precipitation patterns induced by climate change have profound global effects on crop production. Plant functional responses to various precipitation regimes were investigated and it was found that drought and flooding can hinder photosynthetic capacity. However, photosynthetic traits can recover after rewatering, with possible regulative trade-offs in response to episodic drought and subsequent rewatering, enhancing drought resistance and resilience in plants.

Summary: Within a maize canopy, carbon and water fluxes are primarily contributed by the top and middle leaf layers during vegetative growth, while gas exchange processes are mainly carried out in the middle leaves near the ears during the grain-filling stage. Significant relationships were observed between leaf gas exchange rates and ecosystem-level evapotranspiration rates.

Summary: The research shows that under climatic warming, aboveground net primary production of plant community significantly decreases, mainly due to reduced soil moisture induced by climatic warming. Climatic warming also decreases the temporal stability of the plant community by weakening plant species asynchrony and shifting key functional groups.

Summary: This study investigated the ecophysiological responses of three dominant plant species in a desert steppe to precipitation changes and N deposition. The results showed that increased precipitation promoted the leaf photosynthesis rate and N use efficiency of C-3 grasses, and the forbs were more sensitive to water availability, leading to a significant shift in plant community structure and composition.

Summary: The study conducted in a desert steppe over 4 years revealed that precipitation fluctuations significantly affected plant community structure and function, while nitrogen deposition played a role as well. Increased precipitation under high nitrogen levels led to higher aboveground net primary production, but this effect was reversed when the precipitation regime was reversed in the final year. Soil microbial carbon and nitrogen content increased with precipitation, but the reversal of precipitation regime partly eliminated these microbial effects from previous precipitation alterations.

Summary: Vegetation production in temperate and alpine grasslands has not been well studied, and the underlying mechanisms are not fully understood. This study conducted surveys in Inner Mongolia and Tibet, China, to compare temperate grassland (TG) and alpine grassland (AG). The results showed that climatic factors have a greater influence on biomass and precipitation use efficiency than soil and biological factors. Increased precipitation consistently increased above-and belowground biomass, while increased temperature had different effects in TG and AG. The study highlights the divergent mechanisms of biomass production and precipitation use efficiency between temperate and alpine grasslands.

Summary: Climatic change significantly impacts soil microbial communities in arid ecosystems, but the effects of precipitation patterns and underlying mechanisms are unclear. This study conducted a field experiment to examine soil microbial responses to precipitation changes with nitrogen addition. Key findings revealed that increasing precipitation increased soil microbial biomass, while reversing the precipitation treatments reversed these responses. Nitrogen addition reduced the response rates of most microbial groups, and antecedent soil features played a role in distinguishing microbial responses. Precipitation patterns can regulate soil microbial community responses to climatic change through nitrogen deposition and soil chemical and biological mediation.

They observed contrasting and/or consistent relationships between leaf functional traits in the two climate regions. The habitat specificity for these relationships could be a critical determinant of local plant communities and provide insights into plant ecological adaptation and evolutionary strategies.

Summary: Forest soil respiration (Rs) is crucial for the carbon balance of terrestrial ecosystems, but uncertainties exist in its evaluation in China due to the lack of integrated observation data and appropriate upscaling methodologies. This study used a machine learning technique (Random Forest) to re-evaluate the total forest soil carbon effluxes in China, providing reliable estimates and insights into soil CO2 emissions in China's forest ecosystems. The average annual Rs was 776.9 g C m(-2) yr(-1), with a total of 1.17 Pg C yr(-1).
