Insights into Red Deer Ecology during the Late Epigravettian: New isotopic evidence from Riparo Tagliente (Italian Prealps)

Journal of Quaternary Science, EarlyView.
Abstract The transition from the Last Glacial Maximum to the Late Glacial marked a shift from the cold conditions of Greenland Stadial‐2 (GS‐2) to the warmer phases of Greenland Interstadial‐1 (GI‐1), enabling the reoccupation of Alpine regions by Late Palaeolithic hunter‐gatherers.

Floral biology and propagation of blue-flowered Conospermum spp

, 2003
Blue-flowered Conospermum are endemic to Western Australia, and show great potential as cut flowers. Propagation from cuttings or seed proved difficult, and root initiation in vitro is problematic. This thesis examines the floral biology of the species

Late Quaternary climatic variability in the Eastern Mediterranean recorded in Hermes Cave, Corinth Rift, Greece

Journal of Quaternary Science, EarlyView.
ABSTRACT The Greek peninsula lies at the intersection of major atmospheric circulation systems, making it a key location for reconstructing past climate variability in the Eastern Mediterranean. In this study, we present a new high‐resolution multi‐proxy speleothem record from Hermes Cave, located on the shoulder of the Corinth Rift in southern Greece.

A new, ~4500‐year varve record and high‐resolution tephrochronology from lake Hämälänlampi, eastern Finland, provides age constraints for the Furnas C and the Glen Garry/Askja A‐2000 eruptions

Journal of Quaternary Science, EarlyView.
ABSTRACT The northern European distal cryptotephra framework is constantly developing both in terms of identification of new tephra horizons and improved age constraints for the already well‐established tephra marker horizons. However, many prehistoric tephra layers have only been dated by the radiocarbon method, with its inherent problems.

Marine Isotope Stage 4 glaciation in northern England, UK: Evidence from Victoria Cave, North Yorkshire

Journal of Quaternary Science, EarlyView.
ABSTRACT Victoria Cave, north Yorkshire, England, contains a long sequence of Pleistocene clastic sediments and calcite flowstones. Earlier work, using U–Th dating, established that the flowstone units formed in interglacial stages corresponding to Marine Isotope Stages (MIS) 13, 11, 9, 7 and 5.
