Populační a ochranářská genetika rysa ostrovida na okraji Západních Karpat
 Stehlíková, Monika
The diploma thesis deals with the population and conservation genetics of the Eurasian lynx on the edge of the Western Carpathians, including the territory of the Beskydy Protected Landscape Area on the Czech side and the Kysuce Protected Landscape Area on the Slovak side (total ?1500 km2). The aim of the study was to evaluate using non-invasive genetic samples the temporal changes of the genetic diversity and abundance of this marginal lynx subpopulation inhabiting the Moravskoslezské Beskydy Mountains, Vsetínské Beskydy Mountains and Javorníky Mountains during the last five seasons from 2016/17 to 2020/21. Relatedness and spatial activity of selected individuals were also evaluated. The obtained genotypes were supplemented with previously genotyped individuals. In total, 37 individuals (12 females and 25 males) were detected over the period of five seasons. The estimated mean population size was 14 individuals and the effective population size varied between 3.7–7 individuals. The obtained results demonstrate the gradually decreasing genetic diversity of this subpopulation and increasing inbreeding; the inbreeding coefficient in the last season of 2020/21 recorded the highest value of FIS= 0.169. The results also showed that individuals actively reproduced there, at least 15 offspring were identified during this period, some of them settled and reproduced in the area. The spatial activity of the lynx confirmed the interconnectedness of the mountain ranges and the connection of this subpopulation to the West-Carpathian population, which is confirmed by the arrival of several unrelated individuals. In the monitored period, four individuals were also recorded to disperse westwards outside the study area, but all except of one died due to a collision with a vehicle.
