Summary: The input of organic matter into stream channels is an important energy source for headwater ecosystems and plays a crucial role in the global carbon cycle. The study focuses on quantifying the mobilization, transport, and storage of organic-rich fine sediment in a Strahler fourth-order stream during intermediate-sized storm events. It is found that the channel bed is consistently a source of suspended load to the channel margins, and the trapping of suspended load by riparian margins limits sediment transport distance and decouples the channel from local terrestrial organic matter exchange.

Summary: To evaluate the impact of Longyangxia Reservoir construction on the relationship between runoff and sediment load (RRSL) in the upper reaches of the Yellow River, monitoring data of runoff and sediment load are analyzed using the sliding correlation coefficient method and Copula function. The results show that the reservoir construction has a significant impact on RRSL, with a variation point in 1987. Before variation, the correlation between runoff and sediment load is better, but it tends to decrease after variation. This study provides valuable insights into the effects of reservoir construction on runoff and sediment load, and can guide flood control and sediment load-discharge schemes.

Summary: By studying soil samples from different slope directions along an elevational gradient in a mountain ecosystem, we found that soil bacterial diversity and microbial functions exhibit distinct elevational patterns, which are consistent across slope directions. The bacterial diversity shows a hump-shaped pattern, while microbial functions exhibit a linear increasing trend. Additionally, the beta diversity pattern of soil bacteria is significantly influenced by elevational distance decay relationships. Soil bacterial diversity patterns are determined by transitions in community assembly processes, whereas microbial functions are mainly influenced by bacterial community composition.

Summary: Soil respiration plays a crucial role in the global carbon cycle in arid and semi-arid regions, and is regulated by hydrothermal factors. This study examined the seasonal and diurnal dynamics of soil respiration in two typical ecosystems in northern China, and investigated their responses to precipitation, temperature, and drought. The results showed that soil respiration varied seasonally and diurnally, and its response to environmental factors depended on the ecosystem type and soil moisture status. Incorporating multiple factors into carbon cycle models can improve the simulation and prediction of carbon emissions in arid and semi-arid regions.

Summary: Lake drawdown areas, where sediment is exposed due to water level fluctuations, have a significant impact on the carbon cycle. This study examined microbial necromass carbon (MNC) content and its contribution to soil organic carbon (SOC) in different habitats within the drawdown area of Dongting Lake. The results showed that MNC content varied among habitats and was primarily influenced by carbon and nitrogen availability, plant biomass, clay content, and soil moisture. External factors, such as plant and soil properties, played a more crucial role in the long-term accumulation of MNC. These findings enhance our understanding of MNC stability in drawdown areas.
