Cryptic speciation in the field vole: a multilocus approach confirms three highly divergent lineages in Eurasia
Species are generally described from morphological features, but there is growing recognition of sister forms that show substantial genetic differentiation without obvious morphological variation and may therefore be considered 'cryptic species'. Here, we investigate the field vole (Microtus agrestis), a Eurasian mammal with little apparent morphological differentiation but which, on...Pauperio, J ; Herman, Jeremy S ; Melo-Ferraira, J ; Jaarola, M ; Alves, P C …

Post-glacial partitioning of mitochondrial genetic variation in the field vole
Genetic markers are often used to examine population history. There is considerable debate about the behaviour of molecular clock rates around the population-species transition. Nevertheless, appropriate calibration is critical to any inference regarding the absolute timing and scale of demographic changes. Here, we use a mitochondrial cytochrome b gene genealogy,...Herman, Jeremy S ; Searle, Jeremy B
