Mercury cycling during the last glacial period in Arctic Lake El'gygytgyn, NE Russia
Journal of Quaternary Science, EarlyView.ABSTRACT Tectonic processes play a key role in the global mercury (Hg) cycle on geological timescales, by mobilising Hg from deep Earth reservoirs to the surface. These natural fluxes also introduce a dynamic component to the terrestrial Hg cycle that can interact with other environmental signals and influence Hg delivery to sedimentary records.

Geophysical Monograph Series, Page 1-26., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Geographical features and management strategies for microplastic loads in freshwater lakes
npj Clean WaterIn recent years, microplastic contamination in freshwater lakes has become a significant environmental concern. Despite this, there remains a lack of comprehensive understanding of the distribution patterns and regional characteristics of microplastic ...

Land Degradation &Development, EarlyView.ABSTRACT Grazing exclusion is a critical restoration measure for degraded alpine steppe ecosystems. However, research remains limited on the key factors influencing soil aggregates that affect plant productivity and the mechanisms influencing nutrient distribution across aggregates of different size fractions during long‐term grazing exclusion.

Land Degradation &Development, EarlyView.ABSTRACT Urban expansion can substantially reshape ecosystem structure and functioning, especially in ecologically fragile Karst landscapes. Clarifying how ecosystem health (EH) responds to urbanization and identifying the factors that drive spatial variation in EH are important for regional sustainability.

Identifying thermokarst lakes using deep learning and high-resolution satellite images
Science of Remote SensingThermokarst lakes play a critical role in hydrologic connectivity, permafrost stability, and carbon exchange from local to regional scales. Due to the typically small sizes and highly dynamic nature of thermokarst lakes, their identification in large ...

Land Degradation &Development, EarlyView.ABSTRACT Alpine sandy land on the Tibetan Plateau is fragile, with poorly developed soils, low nutrient availability, and weak biological resilience. Vegetation restoration is widely used to improve soil functioning, yet how microbial nutrient limitation and life‐history strategies vary among restoration modes remains unclear.
