Transboundary ecological network identification for addressing conservation priorities and landscape ecological risks: Insights from the Altai Mountains

Ecological Indicators, 2023
Insufficient conservation measures and intense human disturbances gave rise to severe landscape ecological risks (LERs) in transboundary areas, highlighting the significance of transboundary ecological networks to maintain ecological functions and ...

New data on spiders (Arachnida, Aranei) from the caves of Southwestern Siberia (Russia) [PDF]

Acta Biologica Sibirica, 2020
The paper reports six species of spiders from five families found in three caves located in the Altai Krai, Novosibirsk Oblast and Kemerovo Oblast of Russia. One troglophilic species, Improphantes improbulus (Simon, 1929) is recorded from Siberia and the

Hot and cold deserts as eco‐evolutionary arenas for understanding plant resistance to multiple abiotic stressors

Biological Reviews, EarlyView.
ABSTRACT During their long evolutionary history, land plants have evolved a range of adaptations to different abiotic stressors. These help explain present‐day diversity and distribution patterns, as well as the potential resilience of natural and agricultural systems to a changing climate. Most previous research has focused on adaptation to individual

Saussurea × media (Asteraceae), a new natural hybrid between S. parviflora and S. controversa

Nordic Journal of Botany, EarlyView.
Saussurea × media Yusupovsky and E.Pjak (Asteraceae), a new nothospecies from the Altai‐Sayan Mountains, is described and illustrated. In this study, we sequenced the internal transcribed spacer of nuclear ribosomal DNA and the chloroplast intergenic spacers rsp16‐trnQ and ycf4‐cemA to verify the hypothesis of hybridization between Saussurea parviflora

Geomorphometric delineation and subdivision of the Altai mountains using DEM-based analysis

Proceedings of the Mongolian Academy of Sciences
This study redefines the borders, extent, and internal subdivisions of the Altai Mountains - one of the principal mountain systems in western Mongolia - by addressing longstanding inconsistencies in previous geographical and geological interpretations. A

Single‐grain K‐feldspar luminescence dating on primary and re‐deposited aeolian sediments in Mongolia

Boreas, EarlyView.
Owing to its location in the semi‐arid region of northern Central Asia, Mongolia is highly sensitive to climate change and therefore provides an excellent setting for palaeoenvironmental research. Proxy data from different sediment types are crucial for interpreting past climate changes and landscape evolution, while burial ages provide chronological ...

Geomorphological study of the origin of Mongolian Altai Mountains Lake depressions: implications for the relationships between tectonic and glacial processes

Mongolian Geoscientist
The lake depressions in the Mongolian Altai Mountains, and the issues related to their formation have yet to be thoroughly examined in previous research. Previous studies primarily focused on the paleogeographical evolution and glaciation dynamics of the

3D Architecture of Kodiak Butte as Evidence of Fluvial or Shoal‐Water Environments in Jezero Crater, Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract The Mars 2020 mission has explored depositional environments recorded in a fan‐shaped deposit on the western side of Jezero crater. Kodiak butte is an isolated outcrop of sedimentary rock ∼1 km south of the western fan scarp and may be an erosional remnant of said fan.

Long‐term trends in greenness in the alpine zone of northeastern North America from remote sensing

Ecosphere, Volume 17, Issue 9, September 2026.
Abstract Alpine zones above treeline in the Appalachian Mountains and adjacent ranges of northeastern North America support distinctive ecological communities that thrive where conditions are too harsh for trees to grow. These communities differ from alpine zones elsewhere on the continent and are a regionally important source of floristic biodiversity,
