La thèse de Paul DEMANGEON un demi-siècle après : une relecture actualisée dans le bassin de l'Orb (Languedoc, France)

open access: yesPhysio-Géo, 2008
A half-century after the P. DEMANGEON thesis (1959) and despite numerous researches concerning the southern Central Massif, there are no certitudes about the chronology of the erosion surfaces and the uplift stages of the Massif Central.

A new piece in the puzzle: The palaeoecological significance of bryozoans over 7000 years in Daidokutsu Cave (Okinawa, Japan)

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Submarine caves are cryptic, climatically sensitive habitats with long‐term ecological dynamics that are poorly understood. We present the first palaeoecological analysis of bryozoans from Daidokutsu Cave (Okinawa, Japan), based on a sediment core spanning approximately the last 7000 years.

Un littoral sableux en progradation : le lido entre Leucate et Port-la-Nouvelle (Aude, Golfe du Lion, France)

open access: yesPhysio-Géo, 2009
A kinematic study of vertical aerial photos taken between 1952 and 2008 reveals that the Leucate-Port-la-Nouvelle lido (Aude) has prograded of about 15 % in width.

Body Size Regulates Niche Overlap Asymmetry in the Subtropical Andes Rain Shadow: Isotopic Paleoecology of Oligocene South American Ungulates

open access: yesIntegrative Zoology, EarlyView.
This study provides the first isotopic analysis of Oligocene mammals from Quebrada Fiera, Mendoza, Argentina, filling a major gap in South American paleontology. It reveals a latitudinal gradient in aridity due to the Andean rain shadow and highlights the role of (semi)permanent water bodies in sustaining diverse herbivore communities. Additionally, it

The First Quantitative Evidence of Ontogenetic Growth in the Early Cambrian Ecdysozoan Worm Cricocosmia jinningensis Reveals the Earliest Energy Reallocation

open access: yesIntegrative Zoology, EarlyView.
We report the first ontogenetic information for the compression‐preserved Cambrian ecdysozoan worm Cricocosmia jinningensis. Its mosaic growth strategy unifies panarthropod and priapulid developmental patterns. Sclerite allometry reverses at the juvenile‐to‐adult transition, providing the earliest evidence of developmental resource allocation ...

Soil wetting and drying processes influence stone artefact distribution in clay‐rich soils: A case study from Middle Gidley Island in Murujuga, northwest Western Australia

open access: yesArchaeometry, 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.

Development of Nitrogen and Organic Carbon Reference Materials for China Offshore Marine Sediments

open access: yesYankuang ceshi, 2014
The study of marine sediments in China has developed rapidly in recent years, but the standard materials with certified values for nitrogen organic and carbon are relatively lacking.

Response of Remote Tropical West Pacific Islands to Climate Variability: A Multiproxy Record From T‐Lake, Palau, Spanning the Early Holocene to Present

open access: yesArchaeometry, 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.
