Identifying glacio–isostatic rebound processes using testate amoeba as palaeohydrological proxies; a case study from subarctic Québec, Canada

Revista de Geomorfologie, 2018
Glacio–isostatic rebound is one of the most important landscape processes affecting the northern and  northeastern coast of Canada and, therefore, reconstruction of postglacial rebound rates is critical for a better understanding of landscape evolution ...

Assessing the intensity of Late Quaternary humid phases in the Nefud Desert, northern Arabia

Journal of Quaternary Science, EarlyView.
ABSTRACT The climate history of the major dryland zones of the world, such as the Saharo–Arabian Desert belt, plays a key role in the dispersal of early humans through these intermittently inhospitable regions. Here, we assess the relative intensity of Late Quaternary humid phases in northern Arabia through lithological, geochemical, palaeoecological ...

The Diffusion of Humans and Cultures in the Course of the Spread of Farming

, 2017
The most profound change in the relationship between humans and their environment was the introduction of agriculture and pastoralism. [....] For an understanding of the expansion process, it appears appropriate to apply a diffusive model. Broadly, these

Revealing growth increments in fossil and modern otoliths with backscattered electron imaging

Limnology and Oceanography: Methods, EarlyView.
Abstract Otoliths, the functional earstones of teleost fishes, record growth in the form of microscopic increments, making them key archives of individual life histories. While increment analysis is commonly applied to modern otoliths, studies of fossil (Holocene) otoliths remain limited.

Seasonal Exploitation of Migratory Waterfowl at Natufian el‐Wad Terrace, Mount Carmel, Israel

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT Increased avian exploitation is a hallmark of broad‐spectrum subsistence strategies in the Levantine Natufian culture (15,000–11,700 cal. BP). However, detailed publications of bird remains from the Natufian are scant, especially regarding the Early Natufian, and the available evidence shows high inter‐site variability that begs explanation ...

Improving the 14c dating of marine shells from the Canary Islands for constructing more reliable and accurate chronologies [PDF]

, 2012
Radiocarbon dating of closely associated marine mollusk shells and terrestrial material (charred wood or bone) collected from archaeological contexts on Tenerife and Fuerteventura islands allowed us to quantify the marine C-14 reservoir effect (Delta R ...
