Holocene Deformations at the Po Plain–Southern Alps Transition (Lake Maggiore, Italy): Inferences on Glacially vs. Tectonic-Induced Origin

open access: yesGeosciences, 2023
The investigation of deformations in Quaternary deposits holds primary importance in understanding recent geological history and natural hazards in highly populated areas, such as the Po Plain.

North–South Differentiation of Black Flies in the Western Cordillera of North America: A New Species of Prosimulium (Diptera: Simuliidae)

open access: yesDiversity, 2023
Glaciation has been a powerful determiner of species distributions and the genetic structure of populations. Contemporary distributions of many organisms in North America’s Western Cordillera reflect the influence of Pleistocene glaciation. We identified

Palaeoclimate Reconstruction of the Central Gangdise Mountains, Southern Tibetan Plateau, Based on Glacier Modelling

open access: yesLand, 2022
Palaeoglacier modelling is an important approach for reconstructing the palaeoclimate. The timing of glaciations in the central part of the Gangdise Mountains has been constrained previously, but the palaeoclimate remains unclear.

Quaternary chronostratigraphy - a review [PDF]

open access: yesBulletin of the Geological Society of Finland, 1992
Quaternary development is characterized by strong climatic fluctuations associated with repeated glacier expansions. Consequently the Quaternary chronostratigraphy is largely based on the dating of climatic fluctuations which have led to large-scale ...

Late Pleistocene glaciation and retreat of ice sheet on the shelf of the South Orkney Plateau, West Antarctica

open access: yesЛëд и снег, 2021
The research aims to provide insight into reconstruction of the Late Pleistocene glaciations and ice retreat that followed the Last Glacial Maximum. The study is based on multi-channel seismic profiling and multibeam survey conducted on the shelf during ...

Mountains as Evolutionary Arenas: Patterns, Emerging Approaches, Paradigm Shifts, and Their Implications for Plant Phylogeographic Research in the Tibeto-Himalayan Region

open access: yesFrontiers in Plant Science, 2019
Recently, the “mountain-geobiodiversity hypothesis” (MGH) was proposed as a key concept for explaining the high levels of biodiversity found in mountain systems of the Tibeto-Himalayan region (THR), which comprises the Qinghai–Tibetan Plateau, the ...

Changes and representativeness of mountain glaciation parameters

open access: yesЛëд и снег, 2020
The study was aimed at analysis of changes in the area Fgl, the number Ngl and statistical parameters of distribution for different aggregates of glaciers over two periods: 1946–1975 and 1976–2005.
