The role of the Eastern Mediterranean in human evolution: recent results from Greece Le rôle du Bassin méditerranéen oriental dans l’évolution humaine : résultats récents en Grèce

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
The Eastern Mediterranean lies directly on the principal migration route for human groups dispersing across Africa, Europe, and Asia. It also encompasses the Balkans, where fauna and flora, as well as hominin populations, are thought to have persisted through glacial periods.

Holocene Carbon Burial in Lakes of the Uinta Mountains, Utah, USA

open access: yesQuaternary, 2019
Recent research suggests that organic matter sequestered in lake sediment comprises a larger component of the global carbon cycle than once thought, yet little is known about carbon storage in mountain lakes.

The Earliest Feathers from the Lower Cretaceous Dabeigou Formation of North Hebei: Implications for the Early Evolution of the Jehol Biota

open access: yesIntegrative Zoology, EarlyView.
This study reports two isolated feather fossils from the Lower Cretaceous Dabeigou Formation in northeastern China. Morphological analyses identified them as the earliest known feathered theropods (potentially including avian) in the Jehol Biota. This finding reveals a complex ecosystem at the dawn of the Jehol Biota, bridging the temporal and faunal ...

Seasonal lake‐to‐air temperature transfer functions derived from an analysis of 1395 modern lakes: A tool for reconstructing air temperature from proxy‐derived lake water temperature

open access: yesThe Depositional Record
Lacustrine palaeotemperature reconstructions are important for characterising past temperature and hydroclimate change, validating multi‐proxy reconstructions and evaluating global climate models.

Osteological, Biological, and Genetic Consequences of Colonization of Fresh Waters by Marine Cottoid Fishes (Cottidae)

open access: yesIntegrative Zoology, EarlyView.
Lacustrine forms of Triglopsis from North American and European lakes are at different stages of evolution, making them a suitable model for testing hypotheses about evolutionary patterns and rates. An integrative analysis of morphological, genetic, and biological adaptations occurring in lacustrine forms of the genus Triglopsis was carried out.

Uncoupled Histories in the Largest Continental Arc of North America: Goodeid Fishes and Their Gyrodactylid Parasites Influenced Differently by the Trans‐Mexican Volcanic Belt

open access: yesIntegrative Zoology, EarlyView.
• The Trans‐Mexican Volcanic Belt (TMVB) separates the Nearctic from the Neotropics. • TMVB's geology influenced diversification and distribution of endemic goodeid fishes. • Six neartic Gyrodactylus species infect goodeids within and north of the TMVB.

Biometric Analysis of Giant and Large Murid Remains From Matja Kuru 2, Timor‐Leste

open access: yesArchaeometry, EarlyView.
ABSTRACT Published research on Matja Kuru 2 (MK2) demonstrates its significance for understanding human lifestyle during the terminal Pleistocene and Holocene. Murids represent the most commonly identified taxa in the site, with specimens preliminarily classified as small, large and giant based on size comparisons.

Improving the Accuracy of Flow Cytometric Quantification of Microbial Populations in Sediments: Importance of Cell Staining Procedures

open access: yesFrontiers in Microbiology, 2019
The accuracy of flow cytometric (FCM) quantifications of microbial populations in sediments varies with FCM settings, cell extraction and staining protocols, as well as sample types.

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.

Technologies of Transition: Pottery Production and Specialization in Early Rome and Its Neighbors. Neutron Activation Analysis of Regional Assemblages and a Mineralogical‐Petrographic Study of Impasto Chiaro‐Sabbioso

open access: yesArchaeometry, EarlyView.
ABSTRACT The following paper investigates ceramic production and signs of specialization in Rome and the wider region during the early first millennium bce, through an archaeometric approach using Instrumental Neutron Activation Analysis (NAA), and complementary techniques.
