Long‐Term Increases in Ca2+, Mg2+, and SO42− Concentrations in the Kolyma River (1980–2022) Due To Yedoma Degradation

open access: yesGlobal Biogeochemical Cycles, Volume 40, Issue 2, February 2026.
Abstract Permafrost degradation under a warming climate has altered hydrological and biogeochemical processes across the Arctic. Although increasing fluxes of weathering‐derived ions (e.g., Ca2+, Mg2+, and SO42−) have been reported in Arctic rivers, the underlying mechanisms and hotspots within basins remain poorly understood due to limited analysis of

The North Penninic Bündnerschiefer and Flysch of the Prättigau (Swiss Alps) revisited

open access: yesSwiss Journal of Geosciences
During the re-mapping of the area for the Geological Atlas of Switzerland, a significant stratigraphic unconformity was discovered in the North Penninic (Valais) Bündnerschiefer and the Flysch series of the northern Prättigau.

Biostratigraphic constraints for a Lutetian age of the Harrersdorf Unit (Rhenodanubian Zone): Implication for basement structure of the northern Vienna Basin (Austria)

open access: yesGeologica Carpathica, 2019
The formations underlying the Neogene infill of the Vienna Basin are still poorly documented. Until now correlation of subsurface lithostratigraphic units with those of the Rhenodanubian nappe system and the Magura nappe system, outcropping at the basin ...

Mitigating light pollution impacts on arthropods based on light‐emitting diode properties

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
Abstract Light pollution from artificial light at night (ALAN) is a significant environmental problem with far‐reaching consequences for ecological systems. Recent innovations in light‐emitting diode (LED) technology may offer sustainable outdoor lighting solutions, but scientific evidence is lacking. We investigated the effects of various LED lighting

History and present state of the Slano Blato landslide [PDF]

open access: yes, 2005
The Slano Blato landslide is more than 1290 m long, 60 to 200 m wide and 3 to 11 m deep with a volume of about 700 000 m(3). It is located in the Eocene flysch region of western Slovenia with a limestone overthrust in the direct vicinity, above the ...

Towards the optimal Pixel size of dem for automatic mapping of landslide areas [PDF]

open access: yes, 2017
Determining appropriate spatial resolution of digital elevation model (DEM) is a key step for effective landslide analysis based on remote sensing data. Several studies demonstrated that choosing the finest DEM resolution is not always the best solution.

Traits and functions of alpine plant communities respond strongly but not always sufficiently to in situ climate change

open access: yesNew Phytologist, Volume 249, Issue 3, Page 1173-1187, February 2026.
Summary Increasing climate warming and summer droughts are known to affect mountain plant communities, their functional traits and life strategies. However, little is known about how strongly and efficiently communities respond to climate change, and how tightly plant responses are linked to responses of ecosystem functions.

Provenance of the Bosnian Flysch [PDF]

open access: yesSwiss Journal of Geosciences, 2008
Sandwiched between the Adriatic Carbonate Platform and the Dinaride Ophiolite Zone, the Bosnian Flysch forms a c. 3000 m thick, intensely folded stack of Upper Jurassic to Cretaceous mixed carbonate and siliciclastic sediments in the Dinarides. New petrographic, heavy mineral, zircon U/Pb and fission-track data as well as biostratigraphic evidence ...
