No Evidence of Reactive Avoidance of Baboons (Papio ursinus and Papio anubis) to the Presence of Predators

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
In this study, we took advantage of the largest camera trap‐based monitoring project in Africa, Snapshot Safari and analyzed 10,000 camera trap detections from three sites in South Africa and one site in Tanzania to test whether baboons exhibit species‐specific reactive avoidance in response to the presence of predators. ABSTRACT Predators exert strong

"Two tribes": Handaxe shape variation shows distinct regional cultural groups in southeastern Britain between 424 000 and 374 000 BP

open access: yesJournal of Quaternary Science, Volume 41, Issue 4, Page 602-621, May 2026.
ABSTRACT This paper examines regional and chronological variations in Acheulean handaxe morphology during Marine Isotope Stage 11 (c. 425–365 ka BP) in Britain. Using a data set of 737 handaxes from 13 securely dated sites in East Anglia and the Thames Valley, we apply three‐dimensional geometric morphometric analysis to examine morphological ...

Comparing non‐staining methods with Mutvei's solution to visualize growth increments in short‐lived intertidal marine gastropod shells

open access: yesLimnology and Oceanography: Methods, Volume 24, Issue 5, May 2026.
Abstract Mutvei's solution is a widely utilized standard staining method for revealing growth increments in biogenic carbonates; however, it is a slightly toxic, destructive approach with varying success across species groups. Therefore, there has been growing interest in finding non‐toxic, less destructive, and straightforward alternative techniques ...
