Correlation between vegetation pattern and microtopography in periglacial areas of the Central Alps

Pirineos: Revista de Ecología de Montaña, 1990
[es] Se han analizado los modelos de distribución de especies vegetales en microformas periglaciares pertenecientes al tipo de suelos estructurales en el Ortles-Cevedale (Lombardía, Italia).

10Be in the Akademii Nauk ice core – first results for CE 1590–1950 and implications for future chronology validation

Journal of Glaciology, 2017
Temporal variations of the radionuclide 10Be are broadly synchronous across the globe and thus provide a powerful tool to synchronize ice core chronologies from different locations.

Quaternary periglacial silicifications in the Paris Basin

BSGF - Earth Sciences Bulletin
In this paper, and in previous works, quartzites within the Sable de Fontainebleau are clearly shown to occur only near outcrops in Plio-Pleistocene plateau landscapes and are related to groundwater flows.

Characteristics and Climatic Indications of Ice-Related Landforms at Low Latitudes (0°–±30°) on Mars

Remote Sensing
The deposition and evolution of ice-rich materials on Martian surfaces offer valuable insights into climatic evolution and the potential driving forces behind global climate change.

Global threats, local opportunities: ice‐related landforms provide refugia for high‐elevation plants and arthropods

Ecography, EarlyView.
Ice‐related landforms in mountain areas have been hypothesized to play a key role in the survival of cold‐adapted species threatened by climate change. However, our understanding of such landforms acting as refugia remains speculative. Here we analyse occurrence data, collected through a standardized sampling at 471 sampling points across the European ...

The lower altitudinal limit of the periglacial climazonal belt on Kopaonik Mountain (Serbia) [PDF]

Glasnik Srpskog Geografskog Društva, 2019
The morphostructural relief of the highest parts of the central Kopaonik Mt was altered by exogenous agents, by denudation as a primary and periglacial processes as a secondary agent.

Disposition Model for Permafrost Degradation in Mountainous Regions

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Permafrost is a widespread thermal phenomenon in Arctic and high mountain regions that, in combination with steep terrain, exerts a key control on slope stability. Its degradation in response to climatic warming can modify the likelihood and timing of rockfall, debris flow and related mass movements. Robust information on the current state and

The water level regime of periglacial lakes during the growth stage (the lakes of the Tavan-Bogdo-Ola mountain massif, South-Eastern Altai)

Лëд и снег, 2022
Assessment of the dynamics of high-altitude glacial lakes is becoming increasingly important in the context of modern climate instability. The formation of new periglacial lakes and the growth of existing lakes as a result of the reduction of glaciers ...

Evaluating Testability of Permafrost Models Through Physical and Thermal Testing in Complex Mountain Terrain, Yukon, Canada

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Due to its subsurface nature, permafrost cannot be directly observed with the naked eye or optical remote sensing. Consequently, accurately describing its distribution and thermal state is challenging. This is especially true in vast, remote environments, where obtaining comprehensive field data is demanding or improbable.

Uludağ’da Girland ve Çember Oluşumları

Coğrafi Bilimler Dergisi, 2011
Alpine zone of the Uludağ is under the influence of periglacial processes and landforms. As a result of this processes, garlands and circles have appeared to be dominant landforms. Because of the general direction of the Uludağ massif, the summit portion
