Summary: In this study, the provenance of terra rossa soils in two different regions is investigated based on heavy mineral assemblages. Results show that the allochthonous soil components originated from the submerged alluvial plain and Eocene flysch mainly from alpine material. The degree of mineral weathering indicates that the allochthonous component is a parent material of the terra rossa soils, emphasizing the recurring process of terra rossa formation in the northern Adriatic region.

Summary: The sediments of core SCS18-1 from the Beipo seamount in the northern South China Sea mainly originate from fluvial input with some contribution from eolian material. The clay mineral assemblages are stable and mainly come from Taiwan, with the Pearl River and Luzon Islands as secondary sources. The relative content of end-members EM1+EM2 represents the variation of East Asia summer monsoon strength, while the relative content of EM3 reflects the East Asian winter monsoon change. The material supply of core SCS18-1 is mainly controlled by solar radiation in the Northern Hemisphere.

Summary: The heavy mineral assemblages in the sediments of the southern Okinawa Trough were found to be very similar to those from the East China Sea shelf/Yangtze River, mainly composed of mica, chlorite, dolomite, actinolite, and hematite/magnetite. Actinolite and hornblende can indicate the supply of sediments from the East China Sea shelf/Yangtze River to the southern Okinawa Trough. Due to the complex sources, pyrite, epidote, and hematite/magnetite are not adequate indicators for distinguishing between different provenance areas.

Summary: Chemical weathering is a crucial process for the evolution of Earth's surface, but different chemical weathering indices may not always accurately reflect its intensity due to factors like source rocks and grain size. However, variations in the WIP values of fine fraction samples can be used to reflect the intensity of chemical weathering, especially when considering the significant differences in mean annual precipitation between deserts.

Summary: The study found that the REE compositions in eolian sands are influenced by sedimentary sorting and provenance rather than chemical weathering. Among the REE proxies considered, (La/Yb) N and Y/REE values may be affected by sedimentary sorting, while dCe, (La/Sm)N, (La/Gd)N, Y/Tb, Y/Er, and Ce/Nd ratios are more reliable indicators of provenance. Additionally, (La/Sm) N and (La/Gd) N were used as provenance proxies to determine that hinterland lacustrine sediments are significant sources in the eolian sands of the BJD.

Summary: This study analyzed the Mg/Ca ratio and phytolith assemblages of Holocene calcareous root tube samples to reconstruct changes in effective moisture and mean annual precipitation in the Badain Jaran Desert of northwestern China. The results showed that the effective moisture and mean annual precipitation were higher during the 7000-5000 cal yr BP period compared to the 5000-2000 cal yr BP period. The expansion of the lakes in the Early Holocene can be attributed to groundwater input from meltwater, while high lake levels in the Middle Holocene were a result of increased monsoonal precipitation and groundwater recharge. The decline in lake levels in the Late Holocene indicated a relatively arid climate with decreased monsoonal precipitation and groundwater recharge.

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.
