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 ...

Holocene vegetation change and fire–plant diversity shifts in Mediterranean France

Journal of Quaternary Science, EarlyView.
ABSTRACT Changes in fire activity are recognized as a major threat to biodiversity and vegetation communities across the Mediterranean Basin. However, long‐term fire–vegetation interactions remain poorly investigated. Here, we combine a high‐resolution charcoal record with pollen data from the “Étang des Aulnes” lake (southern France) to reconstruct ...

Stable isotope analysis of freshwater gastropod carbonates from Swanscombe: Insights into climate stability and seasonality during MIS 11c

Journal of Quaternary Science, EarlyView.
ABSTRACT Stable isotope analyses of freshwater mollusc carbonate can record environmental conditions at the time of mineralisation, yet this technique remains underused in British Middle Pleistocene fluvial sequences, despite the abundance of fossil shell material in these deposits.

Dental enamel hypoplasia and intra‐tooth isotope records as indicators of physiological stress and environmental variability in Early Pleistocene hippopotamids from Melka Kunture (Upper Awash, Ethiopia)

Journal of Quaternary Science, EarlyView.
ABSTRACT Enamel hypoplasia results from temporary disruptions of enamel deposition during tooth development. It is widely used as an indicator of physiological stress in archeological and paleontological contexts; yet, its relationship with environmental conditions during tooth formation remains poorly constrained.

New Schmidt hammer exposure‐age dating calibrations for the Last Glacial Termination in NW Scotland: Development and application to undated Torridon Group sandstone surfaces in Wester Ross

Journal of Quaternary Science, EarlyView.
ABSTRACT An understanding of the terrestrial extent, retreat dynamics and climate–glacier coupling of ice masses during the Last Glacial Termination (LGT, ~18–11 ka) is often limited by a fragmentary geomorphological record and is dependent on precise, accurate and robust dating frameworks.
