Intensification of Flash and Long‐Term Droughts in the Danube River Basin: A Multi‐Scale Analysis Using Satellite‐Derived Evaporative Stress Index and Soil Water Index

open access: yesInternational Journal of Climatology, Volume 46, Issue 3, 15 March 2026.
Analysed drought intensification in the Danube using Evaporative Stress Index (ESI) and Soil Water Index (SWI). Flesh drought detection: developed thresholds for rapid drought detection using ESI‐4Wk and SWI‐40. Multi‐layer analysis: combined atmospheric stress and soil moisture to assess drought impacts.

Uppermost Jurassic to Lower Cretaceous benthic foraminiferal biostratigraphy at ODP Site 765 on the Argo Abyssal Plain. [PDF]

open access: yes, 1992
Benthic foraminifers were studied in 99 samples collected from the lower 200 m of Hole 765C. The studied section ranges from the Tithonian to Aptian, and benthic foraminifers can be subdivided into five assemblages on the basis of faunal diversity and ...

Multi-aged micro-neighborhood patches challenge the forest cycle model in primeval European beech

open access: yesiForest - Biogeosciences and Forestry, 2020
As currently framed, the forest cycle model that underlies close-to-nature management in temperate beech forests throughout the globe specifies an orderly sequence of temporal development within even-aged patches comprising the forest mosaic.

Stratigraphy, facies and geodynamic settings of Jurassic formations in the Bükk Mountains, North Hungary: its relations with the other areas of the Neotethyan realm. [PDF]

open access: yes, 2013
Jurassic mélange complexes related to the subduction of the Neotethys Ocean occur in the Bükk Mountains, North Hungary. This paper characterizes the sedimentary sequence of basin and slope facies that occur in the southwestern part of the Bükk ...

Veronica paczoskiana is no more than a pine forest ecotype of V. spicata that evolved independently in forest‐steppes of Ukraine and the Altai region

open access: yesNordic Journal of Botany, Volume 2026, Issue 3, March 2026.
The Eurasian steppe area has been a dynamic vegetation biome during the Pleistocene with its repeated cycles of forest advances and retreats. Such a scenario allows the evolution of ecotypes at the ecotone with the potential for parallel evolution in different parts of the distribution area.

Long‐term protection in grasslands enhances soil carbon storage through reduced disturbance and community trait diversity–environment adaptations

open access: yesFunctional Ecology, Volume 40, Issue 3, Page 679-691, March 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Understanding how ecological disturbance and plant community traits regulate soil carbon storage is critical for predicting ecosystem feedbacks to global change and designing sustainable land‐use strategies.

A revision of the Lower Cretaceous foraminiferal genus Falsogaudryinella from northwest Europe and Romania, and its relationship to Uvigerinammina [PDF]

open access: yes, 1995
We emend the definition of the foraminiferal genus Falsogaudryinella Bartenstein, 1977 based on observations of the type species, F. tealbyensis from the Barremian Lower Tealby Clay of Lincolnshire, U.K.

Century‐long trends in plant diversity of temperate mountain vegetation are modulated along elevation gradient

open access: yesJournal of Ecology, Volume 114, Issue 3, March 2026.
Resurvey studies in mountain forests of the Tatra Mountains (Central Europe) show that plant diversity has increased over the past century, particularly at lower elevations. These shifts were associated more with increased nitrogen deposition and reduced grazing pressure than with direct climate warming.

The antioxidant role of low molecular metabolites and polyphenol oxidase of bryophytes in post-technogenic territories

open access: yesБіологічні студії
Background. The antioxidant system (AOS), which includes both high-molecular and low-molecular antioxidants, plays an important role in protecting plants from oxidative stress.

The role of catastrophic floods in shaping the morphology of river beds in small mountain catchment areas

open access: yesLeśne Prace Badawcze, 2017
Mountain streams are subjected to the continuous reshaping of their river beds during floods, with the greatest changes occurring during extreme floods caused by sudden and heavy rainfall.
