Species Limits and Hybridization in Andean Leaf‐Eared Mice (Phyllotis)

Ecology and Evolution, Volume 15, Issue 7, July 2025.
Diversification of Phyllotis coincided with mid‐ to late‐Pleistocene climate change. Species delimitation revealed cryptic diversity within several nominal forms. Genomic analyses revealed evidence for introgressive hybridization. ABSTRACT Leaf‐eared mice (genus Phyllotis) are among the most widespread and abundant small mammals in the Andean Altiplano,

Physical analysis and inverse methods applied to archaeological FIRE replications on ATACAMA desert soils, northern Chile

Archaeometry, Volume 67, Issue 3, Page 625-641, June 2025.
Abstract Physical analysis of in situ fire experiments on soils are useful for the estimation of subsurface thermal diffusivity, which is affected by factors such as water, heterogeneity and heating conditions. To address the uncertainties due to these factors, a new data‐processing procedure based on inverse methods was developed and experimentally ...
