Opposing Trends in Wintertime Convective Initiation Environments of East China Driven by Anthropogenic Aerosols and Greenhouse Gases

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract Winter convection can trigger severe disasters due to low temperature, yet the drivers and mechanisms of regional long‐term trends in winter convective initiation remain unclear. Using homogenized radiosonde data, we reveal the spatially divergent trends in wintertime atmospheric unstable conditions, with a significant decrease in the northern

Adelphomyia crane flies (Diptera, Limoniidae) of Korea with identification key for all Palaearctic species [PDF]

open access: yesZooKeys
Limnophilinae crane flies belonging to the genus Adelphomyia Bergroth, 1891 of the Korean Peninsula were studied starting from 1937, but only one species A. macrotrichiata (Alexander, 1923) has been recorded from North Korea so far. The genus was unknown

Upper Mantle Heterogeneity and Weak Subduction Boundaries Control Crustal Stress in the Korean Peninsula

open access: yesGeophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Most earthquakes occur at plate boundaries, but some also strike within stable continental interiors. Although dominant causes of such intraplate earthquakes remain elusive, a prevailing hypothesis attributes intraplate stress and seismicity to variations in lithospheric thickness.

Genomic Insights and Matrilineal Evolution Reveal Potential Dispersal Patterns of Chitala Species (Osteoglossomorpha: Notopteridae) in the Sundaland Biodiversity Hotspot

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
This study reports the first complete mitochondrial genome of Chitala borneensis and the re‐sequencing of Chitala lopis from Sundaland. Analyses of genetic structure, matrilineal phylogenies, and TimeTree‐based divergence estimates elucidate the evolutionary history and dispersal dynamics of extant Chitala species.

Phylogeny and Biogeography of Calanthe Shed New Light on Alpine Origin and Radiation History of Calanthe Alliance

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
Using nrITS, plastome, and single‐copy SNP data, we resolved the phylogeny of the Calanthe alliance, which originated in the late Oligocene. Its diversification process followed a two‐step pattern: first the warmest Cenozoic interval and Himalayan uplift drove the formation of three major lineages, then sustained Miocene cooling shaped further ...

Spatial Resolution Impact Assessment for Long‐Term Population Monitoring of Adélie Penguin Guano

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
Adélie penguins (Pygoscelis adeliae) are key indicators of the Antarctic ecosystem, and remotely sensed guano stains offer an efficient means of estimating breeding abundance. Landsat medium‐resolution (MR) imagery enables long‐term monitoring through its archive.

Characterization and Identification of Pulsatilla koreana and Pulsatilla tongkangensis Seedlings Based on Morphology, Colorimetric Data, and Molecular Markers

open access: yesNew Zealand Journal of Crop and Horticultural Science, Volume 54, Issue 1, March 2026.
Pulsatilla tongkangensis, an endemic species growing in the limited areas in Korea, is considered endangered species, and is growing in sympatric with P. koreana enabling natural hybridization. To characterize the true to the type of P. tongkangensis, we integrated morphological traits and molecular analyses of the nuclear ribosomal ITS (nrITS) and the

Glacial Meltwater Promotes Biological Productivity and Subsequent Dissolved Organic Carbon Accumulation in the Eastern Ross Sea: Evidence From the Austral Summer of 2023

open access: yesGlobal Biogeochemical Cycles, Volume 40, Issue 3, March 2026.
Abstract The Ross Sea, a critical region for global carbon cycling, receives increasing glacial meltwater from West Antarctica, yet the impact on regional carbon cycling remains poorly understood. A key uncertainty is how this meltwater influences dissolved organic matter (DOM), particularly in the historically inaccessible eastern Ross Sea. This study

Crustal Stress and Strain Energy Density Rates in South Korea Deduced from GPS Observations

open access: yesTerrestrial, Atmospheric and Oceanic Sciences, 2006
An accurate measurement and understanding of horizontal stress rates within the earth¡¦s crust is important for providing fundamental insights into the mechanisms driving plate motion and intraplate tectonic activity.

Winter‐to‐Winter Sea Surface Temperature Anomaly Reemergence in the Yellow Sea

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract The reemergence of winter sea surface temperature anomalies (SSTAs) serves as an effective oceanic memory mechanism, linking winter SSTs across consecutive years in mid‐latitude deep oceans. However, its existence and potential role in modulating SSTA variability in continental shelf seas have remained largely unexplored.
