Conservation genetics of Eurasian lynx in the Western Carpathians
Ungrová, Lenka ; Hulva, Pavel (advisor) ; Kaňuch, Peter (referee)
Robust monitoring combined with genetic analyses are important approaches to protect and manage large carnivore populations successfully. The aim of this master thesis is to analyse Eurasian lynx (Lynx lynx) population within whole Slovakia for the first time using 15 microsatellite loci. Noninvasive genetics is an effective tool for monitoring animal species with large home ranges and low population densities. Noninvasive samples including feces, hair, urine and buccal swabs were collected together with tissue samples from dead (mostly roadkill) individuals. 187 samples were collected between 2017-2019, resulting in 59 successful genotypes. Two samples were incorrectly determined in the field and excluded from further analyses since they were wildcat samples. For population genetics analyses and demography, the dataset from the "Veľké šelmy 2" project was extended with 98 genotypes in collaboration with the Institute of Vertebrate Biology CAS. Overall, 68 lynx individuals were detected in the dataset of 155 genotypes. Relatedness analysis resulted in 67 significant relationships of the first degree and 9 significant relationships of the second degree. These results suggest a high relatedness among the whole population. According to the present thesis, Slovakian lynx population has the third lowest...
Evolution of a dog domestication and genetic diversity of the recent breeds.
Ungrová, Lenka ; Černá Bolfíková, Barbora (advisor) ; Vinkler, Michal (referee)
The origin, timing and the developement of the first stages of domestication are the most frequently studied topics within the evolutionary domestication. Even there are a lot of studies, there are also a lot question that have not been answered. Consequent processes are not less interesting. It is known that the first prototypes of dog breeds were formed much earlier before the first breeding clubs were established. We can say, that the first selection was for the type of work which should be carried by the dog, besides the selection for tameness. The next step of selection included selection for the specific phenotypic traits and often involved targeted hybridization between emerging breeds. Over the past 200 years, more than 400 breeds with a unique combination of traits were recognized. This thesis aims to map the emergence of modern breeds from a genetic point of view. Thesis also summarizes the effect of evolution and domestication on specific traits and genes and how they affected the genetic diversity of dog breeds.
