Summary: Discrete extreme heat events have a significant impact on grassland ecosystems, with heat fluxes and CO2 fluxes showing different responses. Latent heat flux increased significantly during periods of dry and hot weather. Changes in heat flux were determined by changes in solar radiation, while CO2 fluxes were more strongly influenced by exceptional heat during extreme wet or dry events.

Summary: Terrestrial vegetation plays a crucial role in mitigating climate change by acting as a carbon sink. The state of California aims to achieve carbon neutrality by 2045 through managing its terrestrial ecosystems. This study examines the drivers of net primary productivity (NPP) variation and response to water availability extremes in California's grasslands, shrublands, and woodlands. Results show that climate seasonality and water availability extremes influence NPP, but the effects differ across vegetation types.

Summary: This study investigates the responses of temperate grassland (TG) and alpine grassland (AG) to climate change by studying carbon (C) fluxes across different regions in China. The results reveal that water factors consistently increase C fluxes, while temperature factors have opposite effects on TG and AG. The study enhances our understanding of C sinks and grassland sensitivity to climate change.

Summary: Climatic variables have the largest unique contribution to the variance in NEE for forests, while soil properties play a greater role in grasslands. Plant traits have a smaller unique contribution to NEE, and the majority of spatial variance in GPP and RE is attributed to the common contribution of climate, soil, and plant traits. Factors with minor influences on GPP and RE can have significant contributions to the spatial variability in NEE.

Summary: This study analyzed the variations in end date of vegetation growing season (EOS) in temperate grasslands of China and their relationships with climate variations. The results showed that EOS was delayed by 1.62 days/decade. Increasing summer precipitation and autumn temperatures were crucial for delaying EOS. The study also found asymmetric influences of nighttime and daytime warming on EOS.

Summary: Grasslands globally store significant amounts of carbon, providing valuable ecosystem services. However, the impact of livestock grazing on grassland carbon storage remains uncertain. A study in Alberta, Canada found that while grazing reduced litter mass, total ecosystem carbon was 8.5% higher in grazed grasslands compared to non-grazed grasslands, primarily due to increases in soil organic carbon (SOC) and roots. SOC increased consistently in the 0-15 cm soil layer across all climate conditions, with changes in the 15-30 cm layer related to aridity. The increase in SOC under grazing was indirectly attributed to elevated eudicot biomass and improved graminoid quality, leading to enhanced litter and mulch carbon and ultimately higher SOC densities.

Summary: The study reveals that the relationships between climate and carbon and water fluxes in boreal forests are influenced by temperature and water availability. However, the temperature sensitivity and phenological controls have changed over the study period, possibly due to forest structure aging and increased tree mortality following severe drought.

Summary: The study reveals that precipitation, temperature, and evapotranspiration play vital roles in shaping the patterns of aboveground NPP and its partitioning to belowground, with belowground NPP patterns not mirroring those of the aboveground NPP. Despite positive correlations of aboveground NPP and total NPP with mean annual temperature, the fraction of belowground NPP is negatively correlated with it. The relationship between belowground NPP and climatic factors is considerably weak, indicating relative stability regardless of climate conditions.

Summary: The study reveals that functional and taxonomic richness of European grassland communities vary considerably over temperature and precipitation gradients. Overall, they follow similar patterns along climate gradients, except for at high minimum temperatures and wide temperature ranges, where functional richness increases and taxonomic richness decreases. This contrasting pattern may trigger new ideas for studies focused on community assembly processes.

Summary: This study examines the differences and spatial variations in evapotranspiration between forests and grasslands in China. The results show that forests have significantly higher evapotranspiration than grasslands, but the difference becomes non-significant after controlling for precipitation. The effects of latitude and temperature on spatial variations differ between forests and grasslands, with precipitation being the dominant factor. This research contributes to the understanding of evapotranspiration spatial variations in terrestrial ecosystems in China or globally.

Summary: This study investigated the temporal and spatial dynamics of carbon storage in the grasslands of Qinghai, China, using the Biome-BGCMuSo model. The results showed that vegetation carbon density has been increasing since 2000, mainly in the eastern and southeastern regions. Soil organic carbon density also showed a consistent increasing trend, mainly in the southeast and northeast parts of Qinghai.

Summary: Success in conserving biodiversity in rangelands depends on effectively managing the systems to achieve positive economic outcomes while preserving biodiversity. This study found that managing grass height can increase forage mass without replacing native vegetation. However, the impact on grassland bird populations remains unclear. The findings suggest that maintaining grassland bird specialists and potentially increasing livestock production is feasible, but longer time frames may be needed to support endangered tall grass specialists.

Summary: This study aimed to analyze the impact of Turkmen pastoralists' participation in rangeland restoration practices in Aqqala County. The results showed that pastoralists' age, annual income, number of animals, and animal husbandry experience had positive relationships with participatory behavior. Pastoralists who were members of rangeland management cooperatives and participated in training courses performed better in implementation. By identifying the consequences of participatory behavior, barriers to participation in restoration practices can be overcome.

Summary: The distribution of Wyoming big sagebrush has decreased due to its interaction with invasive annual grasses and increased wildfire frequency. Traditional seeding methods have low success rates, while transplanting sagebrush has a higher success rate. Planting younger transplants and controlling invasive annual grasses before planting can increase transplant survival and canopy volume.
