Summary: By studying geological records of organic carbon isotopes, charcoal abundance, and mercury content from a peatland deposit in southwestern China, the detailed history of terrestrial ecosystem collapse during the Permian-Triassic (P-Tr) boundary was reconstructed. The study identified three stages of collapse, which closely followed temperature records and suggested that global warming can trigger deforestation and reduce terrestrial carbon storage, with implications for present-day climate change.

Summary: The use of rice husk biochar at different production temperatures and particle sizes can effectively reduce runoff and soil erosion on mercury-contaminated soil, decreasing the concentration of mercury in runoff and soil. Higher pyrolysis temperature of the biochar results in less runoff, more infiltration, and better erosion prevention, while the effect of biochar particle size is less significant.

Summary: This study investigates the source and degradation of soil organic matter on China's Zoige Plateau, identifying lignin as the main source and tracing its distribution and turnover. Lignin primarily comes from non-woody angiosperm tissues, with litter and roots contributing to topsoil and vertical migration to deep soil. Meadow soil exhibits faster organic matter degradation compared to bog soil.

Summary: C, N, and P in lake sediment play a fundamental role in material and energy cycles. However, research on the impact of lake eutrophication on carbon storage and the influence of river-lake connectivity on nutrient diffusion is still insufficient. This study investigated the accumulation, distribution, correlations, and stoichiometric ratios of C, N, and P in 82 lakes in Eastern China. The findings provide insights into nutrient limitation, sediment carbon sink, and the relationship between eutrophication and sediment carbon storage.

Summary: Plant species diversity (PSD) has beneficial effects on soil organic carbon (SOC) accumulation, and this study explores the mechanisms underlying the stimulative effects of PSD on SOC pools in a subtropical forest. The study finds that PSD enhances soil lignin accumulation through three mechanisms: stimulating plant detritus inputs, increasing reactive minerals for enhanced lignin protection, and lowering microbial C limitation for reduced lignin degradation. These findings provide valuable insights into SOC dynamics under PSD alteration and can be integrated into Earth system models for more accurate predictions.

Summary: Soil erosion is a serious environmental problem in the red soil region of southern China. Through the study of sediments in Huguangyan Maar Lake, it was found that the sediments mainly came from the erosional input of weathering products of wall rocks through catchment runoff. The study reconstructed the soil erosion processes in the Huguangyan Maar Lake catchment over the past 1400 years and explored the potential drivers of soil erosion.

Summary: Urmia Lake, the second hypersaline lake in the world, has experienced an increase in susceptible areas to wind erosion due to decreasing water input caused by human activities. The study found that wind erosion on the edge of Urmia Lake was influenced by the water level of the lake and conservation practices, resulting in a decreasing trend in wind erosion rate from 2017 to 2019.

Summary: This study investigated the accumulation, risk, distribution, and sources of heavy metals in 62 lakes along the Yangtze River. It found that most lakes were contaminated with Cd, with higher ecological risk in the middle reach and southern bank of the Yangtze River. The study also revealed that Cr originated from the natural environment, while Zn, Cu, Pb, Cd and As were affected by human activities.

Summary: This study used pollen and other multi-proxy analyses to reconstruct the history of land use and ecosystem dynamics in central Yunnan Plateau. The results showed that human land use has impacted regional vegetation and landscape since 50 CE, while climate change has mainly influenced vegetation changes.

Summary: This study quantitatively reconstructs soil erosion rates based on lake sediment records from 35 lakes in China and identifies the drivers of soil erosion in different sub-regions of China. The findings show that the evolution of different monsoon systems and regional environments significantly influenced soil erosion processes in China, and human activity played a more important role in soil erosion throughout the Holocene. This study contributes to our understanding of the evolution of soil erosion under different climate systems in China.

Summary: Soil erosion has significant implications for nutrient cycling, land productivity, livelihoods, and ecosystem services. This study presents a spatio-temporal assessment of soil erosion risk in the Winam Gulf, Kenya using the Revised Universal Soil Loss Equation. The results show that soil erosion rates are influenced by rainfall intensity and land cover management, with different levels of susceptibility in different months.

Summary: The use of glyphosate-based herbicides (GBHs) in industrial agriculture is causing a growing concern about the occurrence and spatial distribution of glyphosate and its principal metabolite, aminomethylphosphonic acid (AMPA), in the environment. A study conducted in Quebec, Canada found that 91% of soil samples contained detectable amounts of either glyphosate or AMPA, highlighting the potential spreading and persistence of these compounds in the environment. Glyphosate content was found to be significantly higher in clay soils rich in exchangeable cations.

Summary: During Arctic springtime, atmospheric elemental mercury is oxidized and deposited to the cryosphere by halogen radicals. This is followed by a summertime peak in atmospheric mercury, which is primarily attributed to terrestrial mercury inputs to the Arctic Ocean. The isotope signatures of mercury in the Arctic atmosphere, marine environment, and terrestrial sources reflect the re-emission of mercury deposited during spring. The study suggests that terrestrial mercury inputs remain in the marine ecosystem without substantial loss to the global atmosphere, but may have effects on food webs. The thawing of permafrost due to Arctic warming leads to increased transport of soil mercury to the Arctic Ocean, where it is buried in marine sediment rather than emitted to the global atmosphere.
