Body Size, Dental Pathology, and Maternal Genetic Diversity of Ancient Horses in the Eastern Baltic Sea Region and Western Russia

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT The early evolutionary history of modern domestic horses (Equus caballus/Equus ferus caballus), known as the DOM2 lineage, is well documented due to numerous archaeological and ancient DNA (aDNA) studies. Although many uncertainties remain in the domestication timeline, current evidence suggests that the domestication of modern horses began in

Attribution of subseasonal cold‐spell forecasts to remote drivers using nudging experiments

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Nudging experiments with the European Centre for Medium‐Range Weather Forecasts (ECMWF) model show that Northern European cold spells can arise from different drivers. Some events are predominantly influenced by stratospheric dynamics, while others also involve important tropospheric processes.

Environmental Drivers of Geographic Isolation in Three Pika Species in Northeast Asia

Integrative Zoology, EarlyView.
Using bias‐corrected species distribution models, we found that geographic isolation among three northeastern Asian pika species (Ochotona coreana, Ochotona mantchurica, and Ochotona hyperborea) reflects both divergent environmental preferences and potential competitive interactions. O.

Variation in measuring and ophthalmic factors correlating with central corneal thickness in the Northern Finland birth cohort eye study

Acta Ophthalmologica, EarlyView.
Abstract Purpose To assess the correlation between optical coherence tomography (OCT) and ultrasound pachymetry (USP) as methods for analysing central corneal thickness (CCT) and to evaluate ophthalmic factors affecting CCT. Methods The eyes of 3070 subjects of the Northern Finland Birth Cohort (NFBC) were examined at the age of 45–49 years.
