Reconstructing the late Pleistocene glacial history of the Cairngorm Mountains, Scotland, using paired cosmogenic 10Be and 14C

Journal of Quaternary Science, Volume 40, Issue 6, Page 977-995, August 2025.
ABSTRACT Chronologic and geomorphic evidence of past glaciations is largely recorded in areas at relatively low elevation and/or landscapes defined by high glacial erosion. As a result, data from areas that did not experience significant glacial erosion and the highest elevation locations are lacking from reconstructions of past ice masses.

Historical dynamics of marginal populations at the leading edge of a temperate species in the boreal‐temperate ecotone

Ecosphere
Marginal populations of temperate species at the leading edge of their range will likely play a key role at the boreal‐temperate ecotone (BTE) in the face of climate changes.

Comparing the spatial patterns of climate change in the 9th and 5th millennia BP from TRACE-21 model simulations [PDF]

Climate of the Past, 2019
The spatial patterns of global temperature and precipitation changes, as well as corresponding large-scale circulation patterns during the latter part of the 9th and 5th millennia BP (4800–4500 versus 4500–4000 BP and 9200–8800 versus 8800 ...

Contrasting Effects of Road Dust and Atmospheric Dust on Carbon Accumulation in Eastern Canadian Ombrotrophic Peatlands

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 8, August 2025.
Abstract Limited research has been conducted on the role of atmospheric dust as a nutrient source for peatlands, and none has studied the effects of localized and intense road dust on peatland carbon (C) accumulation. To compare the effects of dust deposition from these two sources on peatlands, we examined three ombrotrophic peatlands adjacent to ...

Holocene Dynamics of Temperate Rainforests in West-Central Patagonia

Frontiers in Ecology and Evolution, 2018
Analyses of long-term ecosystem dynamics offer insights into the conditions that have led to stability vs. rapid change in the past and the importance of disturbance in regulating community composition.

Variaciones glaciales durante el Holoceno en Patagonia Central, Aisén, Chile: evidencias geomorfológicas Holocene glacial variations in Central Patagonia, Aisén, Chile: geomorphological evidences

Andean Geology, 2011
Durante el Holoceno, avances y retrocesos glaciares geomorfológicamente registrados caracterizan la Patagonia. Este artículo presenta la evolución geomorfológica y las evidencias de fluctuaciones glaciales holocénicas de una región patagónica, que ...

Weichselian–Holocene glacial history of the Sjuøyane archipelago, northern Svalbard

Boreas, Volume 54, Issue 3, Page 288-304, July 2025.
To reconstruct the glacial history of Sjuøyane, we describe coastal sedimentary sections in Quaternary sediments and constrain their chronology by radiocarbon and optically stimulated luminescence ages. The sedimentary sections largely consist of shallow (glacio‐)marine and/or littoral sediments deposited during high relative sea levels.

High rates of marine organic carbon burial on the southwest Greenland margin induced by Neoglacial advances

Communications Earth & Environment
Marine sediments in glacially-carved fjords at high latitudes feature high organic carbon (OC) burial rates, but there are fewer data on the role of glacial activity on high-latitude OC burial rates outside of fjords.

Volcanically induced glacier collapses in southern Jan Mayen (Sør‐Jan), Norway

Boreas, Volume 54, Issue 3, Page 395-413, July 2025.
A formerly unknown glacier totally covered with tephra was found in an area of Jan Mayen where no Holocene glaciation was known. This glacier and three others in the same area melted abruptly creating jökulhlaups due to volcanic activity impacting the glacier catchments at different times in the Holocene.

Increased aeolian activity linked to Neoglacial cooling and glacier advance in southern Greenland

Boreas, Volume 54, Issue 3, Page 382-394, July 2025.
Intense aeolian activity observed in the Igaliku Kujalleq records in S Greenland is not related to Norse activities. Instead, we suggest that changes in the North Atlantic atmospheric circulation pattern combined with Neoglacial glacier advances led to increased katabatic wind activity and triggered increased aeolian activity from large outwash plains.
