Modelling of hydrological response to climate change in glacierized Central Asian catchments [PDF]

open access: yes, 2007
The arid lowlands of Central Asia are highly dependent on the water supplied by the Tien Shan mountains. Snow and ice storage make large contributions to current runoff, particularly in summer.

Neotropical Bird Migration During The Ice Ages: Orientation And Ecology [PDF]

open access: yes, 1996
Reconstruction of breeding habitat of North American Neotropical migrants 18,000 years ago and 9,000 years ago indicated major shifts in both location and composition of plant communities relative to present conditions.

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

open access: yesIEEE 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.

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

open access: yes, 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 in shelf phosphorus burial during the Hirnantian glaciation and its implications [PDF]

open access: yesEstonian Journal of Earth Sciences, 2023
The Late Ordovician mass extinction occurred during an icehouse interval, accompanied by the glaciation of the supercontinent Gondwana, which was located at the South Pole at that time.

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

open access: yesEcology 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 ...

Fluctuations of the Vestfonna ice margin at Brageneset, Nordaustlandet, Svalbard, after the last glacial maximum [PDF]

open access: yesBulletin of the Geological Society of Finland, 1995
Four radiocarbon datings of shells of Mya truncata and Saxicava arctica from the till of the end-moraine of the advance of Vestfonna against Brageneset, Nordaustlandet, between AD 1861 and 1899, gave ages between 8300 BP and 8700 BP.

The Glacier Complexes of the Mountain Massifs of the North-West of Inner Asia and their Dynamics [PDF]

open access: yes, 2011
The subject of this paper is the glaciation of the mountain massifs Mongun-Taiga, Tavan-Boghd-Ola, Turgeni- Nuru, and Harhira-Nuru. The glaciation is represented mostly by small forms that sometimes form a single complex of domeshaped peaks ...

Late Quaternary evolution of the sedimentary environment in Modrejce near Most na Soči (Soča Valley, Julian Alps)

open access: yesGeologija, 2020
Geomorphological and geological mapping have long been used to study the glacial history of the Slovenian Alps, but many uncertainties remain regarding the time and extent of Pleistocene glaciations there.
