Depth-dependent propagation of precipitation deficits through the root zone and cropland exposure to soil-moisture drought across China

This study quantifies the depth-dependent propagation of precipitation deficits into soil moisture across China (2000–2022), revealing that while SPI-3 is the most effective meteorological predictor, precipitation indices alone fail to capture the spatially connected, persistent nature of root-zone droughts that disproportionately expose eastern croplands.

Nitrate accumulation in soil profile of different agricultural systems: Magnitude, drivers, and environmental implications

This global synthesis reveals that excessive nitrogen inputs in diverse agricultural systems drive substantial and persistent nitrate accumulation in deep soil profiles, with the magnitude and depth of this legacy strongly modulated by land use type, precipitation patterns, and non-linear thresholds of nitrogen application.

Diversity Evolution of Ordovician Conodonts in the Middle Yangtze Region, South China Block

This study reconstructs the diversity evolution and faunal shifts of Ordovician conodonts in the Middle Yangtze Region, revealing a pattern of gradual diversification peaking in the Ts.2c interval followed by a late Ordovician decline, driven primarily by sea-level fluctuations, climate, ocean chemistry, and tectonic activities.

Who gets to adapt? Climate disasters, state capacity, and unequal adaptive governance

This paper demonstrates that while climate disasters significantly spur national adaptation lawmaking in countries with high institutional capacity, they fail to generate such legislative responses in low-capacity nations, thereby reinforcing global inequalities in adaptive governance.

Unveiling of a trans-oceanic arc system diachronous initiation: Easternmost Neo-Tethyan intra-oceanic subduction record from Bornean peridotite

This study identifies geochemically distinct mantle suites in the Meratus Complex of southeastern Borneo as evidence for the easternmost, diachronous initiation of a trans-oceanic intra-oceanic subduction system in the Neo-Tethys, which evolved from an abyssal to a mature fore-arc setting and formed a >8,000-km arc system by the Late Cretaceous.

The Ground Beneath Changes: Representing Time-Varying Hydraulic Properties in Long-Term Groundwater Models

This study presents a practical framework for incorporating time-varying hydraulic properties into long-term groundwater models, demonstrating that accounting for dynamic changes during mine development, rehabilitation, and closure significantly improves the simulation of post-closure groundwater behavior compared to traditional static assumptions.

Wood Quality and Climatic drivers of Chestnut Tree Growth (Castanea sativa Mill.) and Canopy Stress in Central Italian Coppices

This study on a 37-year-old chestnut coppice in central Italy reveals that wood quality is compromised by basal decay and that radial growth is significantly limited by late-summer drought, highlighting the need for timely silvicultural interventions to mitigate the combined effects of climate stress, pathogens, and aging stands.
