Summary: The study highlighted the importance of accurately quantifying the contributions of climate change and human activities on grassland dynamics for controlling grassland degradation. It found that during the period of 1982-1999, the increase in grassland ANPP was mainly driven by climate factors, while from 2000-2016, the decrease in grassland ANPP was primarily attributed to human activities.

Summary: Grassland is a crucial land resource for human survival and development, but the extent of its global degradation remains uncertain. This study quantitatively explored global grassland degradation trends from 2000 to 2020 and analyzed the driving factors, especially in hotspots. The results showed significant improvement in global grassland since 2000, with Africa and Asia leading in degradation and improvement, respectively. Climate change and human activities were identified as the main driving factors, accounting for a large percentage of grassland degradation and improvement.

Summary: The study found that the CUE of terrestrial ecosystems in the desert/grassland biome transition zone is higher than 0.5 but can vary based on ecosystem type and land use changes. There is a decreasing trend in annual CUE from 2001 to 2017, with most pixels expected to continue decreasing, potentially due to land use changes. Water stress and heat stress were identified as factors that could increase CUE, while the impact of temperature varied across different ecosystems.

Summary: This study explores the dynamics of net primary productivity (NPP) and its influencing factors in the regions near the Tropic of Cancer. The results show that NPP has increased over the past 20 years, with both natural factors and human activities positively contributing to the changes, especially in the eastern region. Vegetation cover is the dominant factor affecting the spatial distribution of NPP. The study emphasizes the importance of human activity-led ecological restoration and protection measures in regional carbon sequestration and balance.

Summary: O-3 pollution in China has been increasing, but its impact on net primary productivity (NPP) of terrestrial ecosystems is unclear. This study uses remote sensing and ground observation data to assess the impact of O-3 on China's NPP. The findings show a significant negative correlation between NPP and O-3 concentration in farmland and grassland ecosystems. The estimated percentage of O-3-induced NPP decline ranges from 5% to 35%, with the highest declines in farmland ecosystems.

Summary: Ongoing climate warming affects biodiversity and ecosystem functions and services. This study conducted a field experiment in Inner Mongolia, China to investigate the effects of warming on grassland stability. The results showed that warming regulated the species diversity-stability relationship, with warming conditions negatively impacting species richness on community variability. Warming also increased species synchrony, species variability, and dominant species variability, leading to increases in temporal variability of community productivity. The size of warming effects on community variability via biotic mechanisms grew with increasing aridity.

Summary: Global warming has had widespread impacts on the terrestrial ecosystem, particularly on vegetation's net primary productivity (NPP). However, the effect of climate variation on the spatial pattern of NPP has remained unclear. This study analyzed the spatiotemporal patterns and trends of MODIS NPP and environmental factors, revealing that NPP increases with elevation in approximately 60% of the global area. Soil moisture exhibits the largest uncertainty, while temperature has the smallest uncertainty among the environmental factors. The dominance of temperature in shaping the elevation distribution of NPP is highlighted.

Summary: Livestock overgrazing and climate change are the main causes of grassland degeneration and biodiversity decline, but the underlying mechanism is still unclear. A meta-analysis of 91 field studies in 26 countries was conducted to analyze the effects of grazing intensity, grazing history, grazing animal type, productivity, and climate on grassland biodiversity. The results showed that the effects of these factors varied across different components of the biome and measurements of diversity, indicating the complex nature of the relationship between livestock grazing and grassland biodiversity.

Summary: This study analyzed the characteristics of vegetation productivity and the effects of climate and human factors in Northeast China. The results showed that climate change played a leading role in promoting the increase of ANPP in most areas, while human activities led to a decrease in ANPP in certain regions. The impact of climate change and human activities varied significantly under different topography and altitudes, with different percentages of ANPP increase attributed to each factor.

Summary: Currently, grassland ecosystems face challenges from climate variability and increased extreme droughts. Ponds in grasslands can play a key role in mitigating climate change pressure and improving grassland resilience. However, their conservation is hindered by difficulties in auditing these small and dynamic features. Understanding the dynamics of pond-grassland interactions with climate change is a priority for assessing future impacts on managed-land systems.

Summary: The impact of land use and land cover change (LULCC) on soil organic carbon (SOC) stock is uncertain and largely unknown due to the choice of land use datasets. Using a process-based model, this study investigated the global SOC changes driven by six LULCC datasets and found significant differences in SOC loss estimates. These differences were mainly attributed to changes in vegetation net primary production in boreal and temperate forests and were more pronounced in low latitude regions. The accuracy of LULCC data is crucial for determining the global carbon budget, highlighting the need for harmonizing satellite observations and inventory data.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Summary: This study investigated the presence of aluminum in human colon cancer samples and its potential association with biological processes involved in cancer progression. Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
