Soil Organic Matter Reduces Persistent Nighttime Surface Warm Bias in Convection‐Permitting U.S. Simulations

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Convection‐permitting modeling has become a cornerstone for improving representation of land‐atmosphere processes, predicting weather extremes, and creating long‐term hydrometeorological data sets. The convection‐permitting Weather Research and Forecasting (WRF) modeling with the NoahMP land‐surface scheme is widely used for kilometer‐scale ...

Study of hydrothermal processes in ice-layers subgrade under constant temperature and dynamic loading

Scientific Reports
The presence of ice-layers in the subgrade soils makes the hydrothermal state of road subgrade built in island permafrost regions more susceptible to external environmental influences.

Vegetation on the move: elevational shifts and greening dynamics across the Himalayan alpine zone

Ecography, Volume 2026, Issue 6, June 2026.
This study investigates alpine ‘vegetation line' (the upper limit of continuous plant community) dynamics in the Himalayan alpine zone (HAZ) over a 24‐year timescale (1999–2022) using maximum NDVI products derived from Landsat series datasets, adjusted for sampling bias using phenological modelling.

Glacial refugia, postglacial dynamics, and hybrid zones of Pinaceae in Eurasia captured from sedimentary ancient DNA

Ecosphere, Volume 17, Issue 6, June 2026.
Abstract Boreal forests cover nearly one‐third of global forest area. Glacial cycles have shaped the distribution and connectivity of modern Pinaceae genera, yet species‐level refugia, postglacial migrations, and hybridization patterns remain unclear due to limited high‐resolution taxonomic and temporal data. We applied a hybridization capture approach

The seed bank created by the dung of large herbivores drives seed circulation in an alpine meadow

Ecosphere, Volume 17, Issue 6, June 2026.
Abstract Seed circulation (i.e., sexual reproduction) is vital for the regeneration of aboveground grassland vegetation (AGV). It occurs in several steps: seed production (seed rain, SR), dispersal (endozoochory, i.e., dung seed bank, DSB), formation of the soil seed bank (SSB), germination, seedling growth, and establishment of adult plants.

Jet Flow Field Analysis of Convergent‐Divergent Nozzle for Hydraulic Perforation for Natural Gas Hydrates

Energy Science &Engineering, Volume 14, Issue 6, Page 3042-3055, June 2026.
Combining the nozzle structure and wellbore size of the second natural gas hydrate trial production, the CFD is employed to analyze the internal and external flow fields of convergent–divergent cavitation nozzle. Analyzing the influence of various structural parameters of the nozzle on its jet performance, and the nozzle configuration with optimal jet ...
