The Anatolian glacial refugium and human-mediated colonization: a phylogeographical study of the stone marten (Martes foina) in Turkey
The Anatolian Peninsula, comprising most of modern Turkey, is situated at the junction of Europe, the Middle East and Asia. Together with its complex geomorphological and climatic history, this has given rise to a rich fauna and flora, which exhibits a wide range of historical biogeographical patterns. The stone marten...Arslan, Yağmur ; Demi̇rtaş, Sadik ; Herman, Jeremy S ; Pustilnik, Jeremy D ; Searle, Jeremy B …

Glacial cycles drive rapid divergence of cryptic field vole species
Understanding the factors that contribute to the generation of reproductively isolated forms is a fundamental goal of evolutionary biology. Cryptic species are an especially interesting challenge to study in this context since they lack obvious morphological differentiation that provides clues to adaptive divergence that may drive reproductive isolation. Geographical isolation... -

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 …

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

Of mice and (Viking?) men: phylogeography of British and Irish house mice
The west European subspecies of house mouse (Mus musculus domesticus) has gained much of its current widespread distribution through commensalism with humans. This means that the phylogeography of M. m. domesticus should reflect patterns of human movements. We studied restriction fragment length polymorphism (RFLP) and DNA sequence variations in mouse... -

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 …

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 …

The Celtic fringe of Britain: insights from small mammal phylogeography.
Recent genetic studies have challenged the traditional view that the ancestors of British Celtic people spread from central Europe during the Iron Age and have suggested a much earlier origin for them as part of the human recolonization of Britain at the end of the last glaciation. Here we propose...Searle, Jeremy B ; Kotlik, Petr ; Rambau, Ramugondo V ; Markova, Silvia ; Herman, Jeremy S …

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

Endemic species may have complex histories: within-refugium phylogeography of an endangered Iberian vole
Glacial refugia protected and promoted biodiversity during the Pleistocene, not only at a broader scale, but also for many endemics that contracted and expanded their ranges within refugial areas. Understanding the evolutionary history of refugial endemics is especially important in the case of endangered species to recognize the origins of...Barbosa, S ; Paupério, J ; Herman, Jeremy S ; Ferreira, C M ; Pita, R …
