Phylogeography of the Tibetan hamster Cricetulus kamensis in response to uplift and environmental change in the Qinghai–Tibet Plateau

open access: yesEcology and Evolution, Volume 9, Issue 12, Page 7291-7306, June 2019., 2019
Major genetic differentiations of Cricetulus kamensis occurred in the late Pliocene. Cricetulus kamensis populations were restricted into two major clades due to tectonic movement of QTP and the Last Glacial Maximum. Abstract Aim The evolutionary process of an organism provides valuable data toward an understanding of the Earth evolution history.

The local paleoenvironment of Kalavan‐2 based on small‐vertebrate remains and its implications for human‐environment‐dynamics between 60 and 35 ka in the Armenian Highlands

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Kalavan‐2, a high‐altitude (∼1640 m a.s.l.) open‐air site in Armenia, preserves stratified Middle Paleolithic occupations with a rich small‐vertebrate record. Luminescence dating has placed site formation between ~60 and 45 ka, but without independent chronological control of the microvertebrate accumulation.
