Genetic variation in field voles (Microtus agrestis) from the British Isles: selective sweeps or population bottlenecks?
The Eurasian field vole (Microtus agrestis) comprises three evolutionarily significant units (ESUs). The northern ESU is found at higher latitudes across the western Palaearctic region and includes six, largely allopatric, mitochondrial DNA lineages that were derived from population bottlenecks. One of these lineages is found in southern Britain and nearby...Herman, Jeremy S ; Stojack, Joanna ; Paupério, Joana ; Jaarola, M ; Wojcik, J M …

Colonization of Ireland: revisiting ‘the pygmy shrew syndrome’ using mitochondrial, Y chromosomal and microsatellite markers
There is great uncertainty about how Ireland attained its current fauna and flora. Long-distance human-mediated colonization from southwestern Europe has been seen as a possible way that Ireland obtained many of its species; however, Britain has (surprisingly) been neglected as a source area for Ireland. The pygmy shrew has long...McDevitt, A D ; Vega, R ; Rambau, Ramugondo V ; Yannic, G ; Herman, Jeremy S …

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

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 …

Land-bridge calibration of molecular clocks and the post-glacial colonization of Scandinavia by the Eurasian field vole Microtus agrestis
Phylogeography interprets molecular genetic variation in a spatial and temporal context. Molecular clocks are frequently used to calibrate phylogeographic analyses, however there is mounting evidence that molecular rates decay over the relevant timescales. It is therefore essential that an appropriate rate is determined, consistent with the temporal scale of the...Herman, Jeremy S ; McDevitt, Allan D ; Kawalko, Agato ; Jaarolo, Maarit ; Wójcik, J M …

Land bridge calibration of rates of molecular evolution in a widespread rodent
There is mounting evidence that rates of molecular evolution decay over recent timescales. Care is needed, therefore, to apply appropriate rates whenever molecular variation is analysed within a temporal context. Given their focus on recent events, intraspecific phylogeographic and demographic studies are particularly vulnerable to erroneous application of rates appropriate...Herman, Jeremy S ; Paupério, J ; Alves, P C ; Searle, Jeremy B

Post-glacial colonization of eastern Europe by small mammals that survived in the Carpathian refugium: evidence from mitochondrial DNA of the common vole
There is now considerable evidence for the survival of temperate species within glacial refugia that were situated at relatively high latitudes, notably the Carpathian Basin and Dordogne region in Europe. However, the prevalence of fossil remains in such locations is rarely matched by molecular evidence for their contribution to subsequent...Stojak, Joanna ; McDevitt, Allan D ; Herman, Jeremy S ; Searle, Jeremy B ; Wójcik, Jan M

Osteoarthritis of the temporo-mandibular joint in free-living Soay sheep on St Kilda
Osteoarthritis (OA) is a common degenerative disease of synovial joints with the potential to cause pathology and welfare issues in both domestic and wild ruminants. Previous work has identified OA of the elbow joint in domestic sheep, but the prevalence of OA of the jaw and in particular the temporomandibular...Stojak, J ; McDevitt, A D ; Herman, Jeremy S ; Searle, Jeremy B ; Wojcik, J M

Post-glacial colonization of eastern Europe by the wood mouse, Apodemus sylvaticus: evidence of a northern refugium and dispersal with humans
The wood mouse Apodemus sylvaticus is an opportunistic rodent that is found throughout most of the European mainland. It is present on many islands around the margins of the continent and in northern Africa. The species has been the subject of previous phylogeographical studies, although these have focussed on the...
