Modeling polar glaciation [PDF]

, 1997
A key measure of our understanding of polar glaciation is the ability to model the initiation, maintenance, and elimination of glaciation over Antarctica and high-latitude land masses in the Northern Hemisphere. Studies that address questions of Cenozoic

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

Frontiers 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 ...

Northern Hemisphere Glaciation during the Globally Warm Early Late Pliocene [PDF]

, 2013
The early Late Pliocene (3.6 to ∼3.0 million years ago) is the last extended interval in Earth's history when atmospheric CO₂ concentrations were comparable to today's and global climate was warmer.

Changes and representativeness of mountain glaciation parameters

Лëд 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.

Routes to global glaciation [PDF]

, 2021
Theory and observation suggest that Earth and Earth-like planets can undergo runaway low-latitude glaciation when changes in solar heating or in the carbon cycle exceed a critical threshold.

Predictive Mapping of Glacial and Fluvioglacial Landforms in the Nadym River Basin (North of West Siberia) With TanDEM-X DEM

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
Remote mapping of glacier and fluvioglacial landforms has been extensively used globally. It is supported by a range of mid-scale spatial datasets (space imaging and digital terrain models) available to the research community.

Mountain uplift and the glaciation of North America – a sensitivity study [PDF]

, 2010
The Miocene (24 to 5 million years ago) wasa period of relative global warmth compared to the Quaternary(2 million years ago to present; e.g. Zachos et al.,2001) and was characterised by the intermittent glaciationof Antarctica only.

Demographic history and gene flow in the peatmosses Sphagnum recurvum and Sphagnum flexuosum (Bryophyta: Sphagnaceae)

Ecology and Evolution, 2022
Population size changes and gene flow are processes that can have significant impacts on evolution. The aim of this study was to investigate the relationship of geography to patterns of gene flow and population size changes in a pair of closely related ...
