Spatial Distribution and Ecological Assessment of Vegetation–Climate Zone Ecotones in the Temperate Forests of South Korea

Ecology and Evolution, Volume 16, Issue 9, September 2026.
Using a national 800‐grid framework, we classified vegetation–climate zones in South Korea into ecotone and core areas based on threshold values derived from zonal statistics. We then integrated species occurrence, climate, topography, and ecosystem service variables to compare biodiversity and ecological characteristics among these zones.

A quantitative procedure for building physiographic units supporting a global SOTER database

Hungarian Geographical Bulletin, 2010
Until recently, manual methods were used for delineating SOILSCAPE. The use of digital data sources, such as digital elevation models (DEM) and satellite data can speed up the completion of digital soil databases and improve the overall quality ...

Climatic niche divergence and high‐elevation adaptation promoted rapid diversification of Pimoa spiders in Pan‐Himalaya

Ecography, Volume 2026, Issue 9, September 2026.
The Pan‐Himalayan region harbors exceptional biodiversity, yet the origins and underlying mechanisms driving this remarkable diversity remain poorly understood, especially among species‐rich invertebrates. Pimoa spiders exhibit an intercontinental disjunct distribution across three major mountain regions: the Rockies, the Alps, and the Pan‐Himalaya ...

Optimizing Regional Flood Frequency Analysis for Floodplain Mapping and Risk Reduction

Engineering Reports, Volume 8, Issue 9, September 2026.
The estimation of flood hazards in river basins under monsoon conditions and data‐scarce situations is a challenging task due to the scarcity of the streamflow measurements and the high variability of the distribution of the rainfall. This paper provides a detailed framework for flood modeling and inundation mapping for a specific sub‐catchment of the ...

Predicting Seismic Intensity Using Machine Learning With Ancillary Data: Evidence From Destructive Earthquakes in China

Engineering Reports, Volume 8, Issue 9, September 2026.
A machine learning framework integrating multisource seismic, social, and geographic data accurately predicts kilometer‐scale seismic intensity, enabling rapid postearthquake damage assessment during data‐scarce “black‐box” periods. ABSTRACT Accurate and rapid assessment of seismic intensity is crucial for postearthquake emergency response.

Morphological Changes and Alterations in Erosion–Accretion Patterns in a Semiarid Brazilian River

Earth Surface Processes and Landforms, Volume 51, Issue 9, September 2026.
Flow regulation by the Castanhão Dam significantly altered discharge dynamics and reduced sediment transport in the Jaguaribe River. Long‐term analysis (1958–2025) reveals attenuated flood peaks, decreased channel migration and progressive downstream stabilisation, highlighting persistent geomorphic adjustments in a regulated semiarid fluvial system ...
