| Popis | The dispersion and mating system significantly affect the genetic structure of the population. Boreal owl (Aegolius funereus) nesting biology has been studied since 1999 in the Krušné Hory Mts where the birds nest in nesting boxes. To investigate the mating system and the population genetic structure of the boreal owl population, blood samples have been collected there since 2006. We collected 241 samples from family members in 3 years period from 3 different areas - Krušné hory Mts, Jizerské Hory Mts and Žďárské Vrchy Mts. These samples were genotyped at 7 microsatellite loci. We found no evidence of EPF in any of them; only two nestlings had genotypes that were incompatible with those of their parents. In both cases, however, the genotypes of the chicks were inconsistent at only one locus. The results indicate decrease in the genetic diversity of population from the Krušné Hory Mts, which is probably the effect of relatively high rate of resident individuals in the area of study, including females. The FST values and the output of the Structure program indicate genetic differentiation among all three localities. That could be caused by the limited gene flow between the mountain range or by the number of samples. |
