Methods in Ecology and Evolution, EarlyView.Abstract Detecting environmental DNA (eDNA) from rare or low‐abundance aquatic species remains a major challenge, particularly when it is highly degraded, present at low concentrations, and dominated by DNA from non‐target taxa. These challenges are further amplified in sedimentary ancient DNA (sedaDNA) studies, where thousands of years can degrade ...

Geochronology of the Upper Ice Complex (Yedoma) exposed in the Batagay Megaslump, East Siberia
Arctic, Antarctic, and Alpine ResearchThe Batagay Megaslump in eastern Siberia exposes one of the oldest permafrost archives and provides insights into Beringian paleoenvironments. However, its geochronology calls for improvement given known difficulties with permafrost dating and current ...

RADIOCARBON DATING: PAST, PRESENT-DAY AND FUTURE - DEVELOPMENT OF I.P. GERASIMOV IDEAS
Бюллетень Почвенного института им. В.В. Докучаева, 2015 The ideas of I.P. Gerasimov on the radiocarbon soil age are outlined; the notions of absolute and relative soil age introduced by him are defined. Current trends in organic matter dating are discussed.

Arabian Archaeology and Epigraphy, EarlyView.ABSTRACT In 2019, the Dadan Archaeological Project (CNRS/RCU/AFALULA) identified a Late Antique village 1 km south of ancient Dadan in the al‐ʿUlā valley (northwest Saudi Arabia). Three excavation seasons at this site (2021–2023) have uncovered a massive building constructed in the late third or early fourth cent.

Archaeometry, EarlyView.Abstract Soils that contain swelling clay minerals (e.g., montmorillonite) expand and contract during wetting and drying, causing movement within the soil profile. This process, known as argilliturbation, can alter artefact distributions, destroy stratigraphy and complicate the interpretation of archaeological deposits.

Radiocarbon Dates Documenting the Neolithic-Bronze Age Transition in Korea
, 2010 We report radiocarbon dates for ~150 archaeological sites in Korea belonging to the Neolithic-Bronze Age transition period. From the present compilation, we find that the Neolithic-Bronze Age transition in Korea started as early as ~2300 BC and continued

Archaeometry, EarlyView.ABSTRACT Lake sediments are natural archives of past environmental dynamics and how these systems have responded to past climate variability. Sediment geochemistry, governed by local geology and climate processes, is unique to each lake‐catchment and geochemical proxies must be validated for each study site.

Archaeometry, EarlyView.ABSTRACT Human skeletal remains constitute critical archaeological evidence for reconstructing past societies, yet their investigation requires careful ethical, cultural, and legislative consideration. This paper reports on the discovery, recovery and analysis of a set of skeletal remains encountered during a cultural heritage management (CHM ...
