Hájková, H. Hauffe (Centre for Alpine Ecology, Trento, Italy), A. Dominguez (Universidad de Oviedo, Spain), S. Hammer (University of Veterinary Medicine, Vienna, Austria) The chamois provides an excellent model for exploring the effect of historical and evolutionary events on diversification. Genetic differentiation and geographical distribution of the divergent lineages show the effects of patchy distribution of populations, limited latitudinal range expansions, contractions and hybridizations.Articles:Rodríguez F., Hammer S., Pérez T., Suchentrunk F., Lorenzini R., Michallet J., Martínková N., Albornoz J., Domínguez A. 2009: Cytochrome b Phylogeography of chamois (Rupicapra spp.).

Heredity 100: 691-708Post-glacial life history of stoatsNatália Martínková, collaboration with JB Searle (University of York, UK)The current Irish biota has controversial origins. Ireland was largely covered by ice at the Last Glacial Maximum (LGM) and may not have had land connections to continental Europe and Britain thereafter. Given the potential difficulty for terrestrial species to colonize Ireland except by human introduction, we investigated the stoat (Mustela erminea) as a possible cold-tolerant model species for natural colonization of Ireland at the LGM itself. Our data suggested an LGM colonization of Ireland and later colonisation of Britain. This later colonization probably reflects a replacement event. The molecular data strongly indicate that stoats colonized Ireland naturally and that their genetic variability reflects accumulation of mutations during a population expansion on the island.Articles:Martínková, N., McDonald, R.

Žiak (Comenius University, Slovakia) The Tatra vole is an evasive, endangered rodent endemic to the Carpathians. Its distribution is probably fragmented, and it is believed to live in social groups. The aim of this project is to test these hypotheses using population genetic tools.Articles:Rudá M., Žiak D., Kocian Ľ., Martínková N. 2010.
