Comparison the Brown bear (Ursus arctos L.) population genetic characteristics based on the microsatellite markers - ‘DNA fingerprints’ around the world and their application for biotracking
AbstractThe evaluation of selected Brown bear population genetic attributes based on microsatellites is reviewed in this article. In order to design a study comparative population genetics a group of markers which comparable to other bear studies had to be selected. Different projects around the world offer a selection of the most frequently used microsatellite loci and their properties. Microsatellite variability can be explored in different terms. Differences in genetic characteristics between populations can be reflected via expected and observed heterozygosity, polymorphic information or coefficient of inbreeding. The question of how many microsatellites markers are necessary for discerning individuals had to be answered. Degree of the allelic variability can reflect the gene flow between populations and genetic drift or mutation rates. Acquired microsatellites data evaluation and in particular in finding answers to the question of individuals distribution on the site led them to propose procedures for comparation of microsatellite data was processed using our original Java script software methods. A global overview of microsatellite loci tested in different areas in the Europe, Asia or America is also presented in the summary table with the collection of all applied loci.
