Has hydrological alteration driven ecosystem service risks in large floodplain lakes? A novel framework for spatiotemporal assessment and hydrological thresholds identification

Study region Poyang Lake, China’s largest freshwater lake, is a critical ecological hub. Study focus Hydrological alteration strongly affects floodplain ecosystem services (ES), yet their spatiotemporal risks and hydrological controls remain poorly understood. We developed an int...

Spatial distribution of soil macronutrients and nutrient index for sustainable agriculture in the Khulna region of Bangladesh

Abstract Purpose Evaluation of soil fertility is essential for sustainable agriculture; yet studies on nutrient distribution indices, particularly in Bangladesh, remain limited despite increasing research. The purpose of this study is to identify nutrient indices and create spati...

Three Gorges Dam-driven redistribution, sediment-water partitioning, and health risks of heavy metals in the Yangtze River

The Three Gorges Dam (TGD), the largest hydraulic project on the Yangtze River mainstream, has altered hydrodynamic regimes and sediment transport. However, how its interplay with basin-scale pollution control policies regulates heavy metal behavior remains poorly understood. The...

Runoff Simulation and Analysis in the Upper Yellow River Basin Using a Budyko–XGBoost Coupled Model

The Upper Yellow River (UYR) basin is the predominant runoff-yielding area of the entire watershed. Accurately simulating annual runoff is crucial for water resources management. While the Budyko framework effectively captures long-term hydro-thermal equilibrium, it struggles to...

The Zooplankton International Geospatial dataset: A global repository of spatiotemporal freshwater zooplankton community composition data from lakes and reservoirs to support ecological research

Abstract Zooplankton transfer substantial energy in aquatic food webs and are used as indicators of environmental change. Syntheses of zooplankton community dynamics globally require datasets that span a wide range of environmental gradients; however, these datasets are limited d...

Engineering and land use intensified climate-driven Yangtze River flood hazards since the Little Ice Age

Understanding the interplay between climate variability and human activities is essential for assessing long-term river flood hazards. Yet, the relative contributions of natural and anthropogenic drivers to flood magnitude remain poorly constrained due to limited multicentury rec...
