Plant migration and ice age

Plant migration and ice age

Objective

Major climatic changes during the Pleistocene and early Holocene influenced the contemporary plant diversity in Europe the most. In that time of advancement and retreat of glaciers, many types of new habitats appeared and disappeared accompanied by massive migration, fragmentation and extinction of populations. The southerly situated European regions are supposed to be glacial refugia of many arcto-alpine plant taxa during glaciations and after the last retreat of glaciers served as genetic pool for northwa rds migration. At the same time, Pleistocene refugia are regarded as places with higher inter-specific diversity, but also by intraspecific diversity or hot spots of biodiversity. European arcto-alpine flora is distributed in two major and during the last Holocene isolated arelas: the northern parts of Fennoscandinavia and adjacent parts of northern hemisphere; and the high mountain ranges of continental Europe. Thus, the species with the disjunctive range of distribution may serve as an interesting model f or study of genetic diversity and historical biogeography. Our specific objective is to search for phylogeographic patterns of perennial arcto-alpine species Hieracium alpinum L. (Asteraceae) in a whole part of its range, covering Alps, Carpathians, Sudete n, Harz, Vosges, Fennoscandinavia, Scotland, Island, Greenland and Murmansk Region. Special attention will be paid to the determination of putative glacial refugia and to the migration routes. In order to accomplish our aim, we will use the single nucleoti d polymorphism (SNP) of non-coding regions of chloroplast DNA and amplified fragment length polymorphism (AFLP) as tools for measurement of genetic diversity. The proposed molecular project will be among the first to investigate general biogeographic patte rns of arcto-alpine plants and provide population genetic data from ca 100 populations on the large geographic scale of Europe covering a whole range of species.
