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

open access: yesEcology 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,
