Spatial molecular ecology of the brown bear in Western Carpathians
Šrutová, Jana ; Hulva, Pavel (advisor) ; Hájková, Petra (referee)
In the current human-dominated landscape, wildlife populations are more often exposed to the island effect, loss of genetic variation and the associated risk of extinction vortex. Landscape genetics studies microevolutionary processes in populations and their relationships to landscape features. Integration of the results of genetic analyses and the results of habitat modeling of the species under study helps to identify transition zones between suitable habitats or anthropogenic barriers to gene flow in the landscape. Analysis of the spatial population structure of wildlife populations is an important tool for the conservation and management of populations. Between 2019-2021, 2172 mostly non-invasive brown bear (Ursus arctos) samples were collected in Slovakia, mostly collected in the Western Carpathian region. Using a microsatellite panel containing 10 polymorphic loci and the SRY gene for sex determination, a total of 1036 genotypes were identified, including 632 unique genotypes. The population seems to be relatively diversified and the observed heterozygosity is comparable to other demographically stable bear populations in Europe. Using STRUCTURE, a Bayesian clustering analysis was performed, which divided the population into three or four subpopulations according to the selected method. The...

Development of populations of brown bears (Ursus arctos) in Slovakia hľadať
LICHÝ, Radoslav
The intention was on the basis of available statistical data and field investigations to assess the development status of the population size of brown bears in Slovakia. To evaluate changes in brown bear habitat and to propose realistic recommendations for additional protection and possible management. On the basis of sociological investigations, we found the position of nature protection, senior management of nature conservation and hunting organizations to the current issue. Through media monitoring, we found the level of public awareness on the issue of brown bear in Slovakia. hľadať
