The predatory behavior of ants: an impressive panoply of morphological adaptations

Insect Science, EarlyView.
This review focuses on predation in ants, showing the wide diversity of cases from solitary foraging to group hunting tactics, as well as the evolution of mandible shape frequently adapted to capture specific prey. Although most ants are generalist feeders, finding their sugary substances directly on plants or indirectly via sap‐sucking insects, some ...

Inferring bird migration from bone isotopes and histology: A fossil‐friendly methodological framework

Methods in Ecology and Evolution, EarlyView.
Abstract Bird seasonal migration is a remarkable biogeographic phenomenon, yet its deep‐time origin(s) and evolutionary history remain poorly understood, with the bird fossil record largely overlooked. This study explores the predictability of bird migratory behaviour from the oxygen isotope composition of their bone apatite phosphate (δ18Op), a ...

Late Cretaceous

Abstract The Upper Cretaceous is one of the rare stratigraphic intervals in the Netherlands that can be studied in outcrop. The quarrying of chalky limestone and interbedded chert nodules in South Limburg has contributed to the study of these rocks and their notable fossil content. During the Late Cretaceous, a transgression which had

Relationship and Source of Whitings Used as a Painting Ground in Icons From Polish Museum Collections Based on Their Calcareous Nannofossil Content

Archaeometry, EarlyView.
ABSTRACT In icon painting, chalk whiting is key to creating a gesso ground, providing a smooth, absorbent surface for paint. Calcareous nannofossils, tiny marine skeletons found in chalk, are an ideal tool for analyzing the origin of an icon's chalk ground, often the only reliable information about where the icon came from.

Assessing Mobility Among Inferred Elites Interred in Crypts 1–3 on Kom H at Tungul (Old Dongola), Sudan

Archaeometry, EarlyView.
ABSTRACT As the capital of Makuria, Tungul was a major sociopolitical center within medieval Nubia, being the seat of a bishopric and a monastic community. During the excavation of the Kom H monastery, three burial crypts (Crypts 1–3) were uncovered.

Palaeoenvironmental changes recorded at the Velika Vrbica loess‐palaeosol sequence, Wallachian Basin, during MIS 3–MIS 1

Boreas, EarlyView.
This study presents a detailed investigation of the Velika Vrbica loess‐palaeosol sequence, situated in the Wallachian Basin of northeastern Serbia, with the aim to reconstruct palaeoenvironmental changes spanning Marine Isotope Stages (MIS) 3 to 1. Using optically stimulated luminescence (OSL) dating, low field magnetic susceptibility (χlf), and mass ...
