Decoupling glacier retreat and surface stabilization on the Snežnik Plateau (Slovenia), insights from in situ cosmogenic 36Cl exposure and depth‐profile ages

Journal of Quaternary Science, EarlyView.
ABSTRACT Glaciokarst landscapes pose distinctive challenges for cosmogenic dating because meltwater and runoff can be rapidly rerouted into ponors and conduit networks, weakening glacier–river coupling and promoting local sediment storage. We reconstruct glacier retreat and postglacial stabilization on the Snežnik Plateau (SW Slovenia) using in situ ...

Radiocarbon Ages of a Possible Titian’s Painting

Heritage
A radiocarbon study of a painting that might have been made by Titian or Tintoretto or by their workshops is presented. It could be the lost Titian self-portrait or, more convincingly, the sitter might be the Venetian Andrea Cappello, elected Procuratore de Supra in 1537 AD.

Holocene vegetation dynamics of Grande Terre (Kerguelen Islands) inferred from sedimentary ancient DNA

Journal of Quaternary Science, EarlyView.
ABSTRACT While the Antarctic region has experienced significant climatic changes over the Holocene, few high‐resolution records have examined their effects on the local biota. In order to understand past ecological shifts and forecast future changes, it is important to obtain high‐resolution palaeoecological records from this region.

Direct radiocarbon dating and stable isotopes of the neandertal femur from Les Rochers-de-Villeneuve (Lussac-les-Châteaux, Vienne)

Bulletins et Mémoires de la Société d’Anthropologie de Paris, 2006
Direct radiocarbon dating of the Neandertal femoral diaphysis from the Rochers-de-Villeneuve (Lussac-les-Châteaux, Vienne) has yielded an age of 45,200 ± 1,100 14C years B.P. (OxA-15257) [48,455 ± 1,878 cal. years B.P.], and stable isotope values of δ13C

AMS Radiocarbon Dating of Large Za Baobabs (Adansonia za) of Madagascar. [PDF]

PLoS ONE, 2016
The article reports the radiocarbon investigation of Anzapalivoro, the largest za baobab (Adansonia za) specimen of Madagascar and of another za, namely the Big cistern baobab. Several wood samples collected from the large inner cavity and from the outer

SYSTEMATIC ANALYSES OF RADIOCARBON AGES OF COEXISTING PLANKTONIC FORAMINIFERA

Radiocarbon, 2023
ABSTRACTWe compare radiocarbon (14C) ages of coexisting planktonic foraminifera species from sediment cores VM12-107 and KNR166-2-26JPC from the Equatorial Atlantic Ocean for three time periods (Holocene, Heinrich Stadial 1, last glacial maximum). We find a maximum inter-species difference of 120014C yr.

Marine radiocarbon reservoir age simulations for the past 50,000 years

, 2017
Radiocarbon (14C) dating calibration for the last glacial period largely relies on cross‐dated marine 14C records. However, marine reservoirs are isotopically depleted with respect to the atmosphere and therefore have to be corrected by the Marine ...

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 ...
