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

Journal 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.

Russian wheat aphid: a model for genomic plasticity and a challenge to breeders

Insect Science, EarlyView.
Invasive foundress finds suitable habitat and reproduces through pathogenesis. Wingless females produce life offspring quickly, which leads to high population densities. High population densities result in competition, which may induce epigenetic changes and wing development for dispersal.

Bridging the Late Antique Gap in Northwest Arabia: New Archaeological Evidence on the Occupation of Wādī al‐Qurā (al‐ʿUlā [AlUla], Saudi Arabia) Between the Third and Seventh Centuries CE

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.

Down with the roots. Phytoliths as biocultural traces in historical olive agroecosystems of Sicily

Frontiers in Ecology and Evolution
Within the multidisciplinary framework of historical ecology, in this study plant morphology, oral history, and soil analyses are combined with phytoliths to reconstruct shifts in management and environment of historical and living olive agroecosystems ...

Lithic analysis in African archaeology: Advances and key themes

Archaeometry, EarlyView.
Abstract Stone artifacts (lithics) preserve for extended periods; thus they are key evidence for probing the evolution of human technological behaviors. Africa boasts the oldest record of stone artifacts, spanning 3.3 Ma, rare instances of ethnographic stone tool‐making, and stone tool archives from diverse ecological settings, making it an anchor for ...

Oviposition Site Selection in Relation to Hatchling Feeding Performance in Two Sympatric Papilio Butterflies

Entomologia Experimentalis et Applicata, EarlyView.
We investigated oviposition site selection and hatchling feeding performance in two sympatric swallowtail butterflies, Papilio xuthus and Papilio memnon (Lepidoptera: Papilionidae), that utilize Citrus trees as host plants. Our study suggests that each species has unique relationships between maternal oviposition preferences and hatchling feeding ...

When biology meets materials science – Interdisciplinary applications of electron microscopy

Journal of Microscopy, EarlyView.
Abstract Research at the interface between biology and materials science creates challenges for electron microscopists. Everything from the sample preparation to the choice of imaging and analytical techniques and the interpretation of the resulting data refuses to sit comfortably within the domain of one discipline or the other.

Reconstructing Cenozoic grasslands in North America and western Eurasia: evidence for cold‐season grasses from 3D phytolith morphology

New Phytologist, EarlyView.
Pie charts illustrate the composition of fossil grass silica short‐cell phytolith (GSSCP) assemblages at investigated fossil sites in the United States and Türkiye and representative 3D meshes of classified phytoliths. Summary Pooideae, the largest grass subfamily, radiated in the Northern Hemisphere from the Paleocene onward and today dominates cold ...
