Refinement of the Quaternary seismic stratigraphy and analysis of buried glacial channels on the Labrador Shelf

Journal of Quaternary Science, EarlyView.
ABSTRACT The Laurentide Ice Sheet covered vast areas of North America during the Wisconsinan, including the Labrador Shelf, off the coast of eastern Canada. The shelf is characterized by glacial cross‐shelf troughs, which have been considered as predominantly eroded by the last ice advance.

Can DNA from wet, temperate soils be used for palaeoecological reconstruction?

Journal of Quaternary Science, EarlyView.
ABSTRACT Sedimentary ancient DNA in well‐dated contexts (sedaDNA) has great potential as a palaeoecological proxy. A few studies have attempted palaeoecological reconstructions using sedaDNA from soil; these studies have been mainly restricted to cold and/or dry soils.

Insect communities of late Pleistocene steppe–tundra and Holocene boreal forest ecosystems in central Yukon Territory, Canada

Journal of Quaternary Science, EarlyView.
ABSTRACT Subfossil insect communities from the Quartz Creek site provide a detailed record of both Late Pleistocene steppe–tundra and Holocene boreal forest ecosystems in central Yukon Territory, Canada. Fifteen Pleistocene assemblages (marine isotope stages [MIS] 4 to 2) are dominated by steppe–tundra and dry‐tundra taxa, particularly the weevils ...

New geochronological constraints on Late Pleistocene glaciation in the southern Cadí Massif, SE Pyrenees

Journal of Quaternary Science, EarlyView.
ABSTRACT The Cadí Massif (42°17′09″ N, 1°38′11″ E; 2649 m a.s.l.) in the southeastern Pyrenees preserves clear evidence of Late Pleistocene glaciation, although previous research has focused almost exclusively on its northern slope. By contrast, the southern slope has remained largely unexplored.

A talus rock glacier in Nantlle Valley, North Wales

Journal of Quaternary Science, EarlyView.
ABSTRACT Landforms comprising mixtures of fine and coarse sediment and deposited during late glacial times are ubiquitous in the British mountains. In many cases, their interpretation has often proved contentious; as a result, the non‐generic term discrete debris accumulations (DDA) has been used to describe them and, over the last 50 years, some have ...
