Spatial and flight activity of the maternity colony of the Mediterranean horsheshoe bat Rhinolophus euryale in Slovak Karst
Jehličková, Veronika ; Benda, Petr (advisor) ; Kaňuch, Peter (referee)
In the pre-lacation, lactation and post-lactation periods in 2010 and 2011 and the pre-lactation period in 2012 we used radio-telemetry to determine changes in home range and habitat activity and preference of the maternity colony of the Mediterranean horseshoe bat (Rhinolophus euryale) in Slovak Karst. The colony roosted in the attic of the monastery in Jasov. This area represents the northern margin of the species distribution range. In total, we tagged 35 females that were radio-tracked for 31 nights. For the all pre- lactation periods 17 females were marked, in the lactation periods 12 females were marked, and 6 females were marked in the post-lactation periods. The females were marked with radiotags and the VHF telemetry (radio telemetry using very high frequencies) was used. We compared the spatial and habitat preferences in the above defined seasons of the annual reproductive cycle. The total number of recorded locations was 858 for all reported periods. We compared the varios aspects of activity of the females during the night in the particular periods. We have shown that the females left their roost in the pre-lactation periods as the most late. These were followed by the females in the lactation periods and as the most early after the sunsetthe roost was left by the females in the...
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...
Population genetics of Pipistrellus pipistrellus species complex hibernacula
Habalová, Kateřina ; Hulva, Pavel (advisor) ; Kaňuch, Peter (referee)
This thesis deals with two cryptic pipistrelle bat species, common pipistrelle (Pipistrellus pipistrellus) and soprano pipistrelle (Pipistrellus pygmaeus) living in sympatry in continental Europe. Although both species are abundant during summer in Europe, they spent winter in mass hibernacula and there is only limited knowledge about this period. In total, 233 individuals from four mass hibernacula were sampled in Central Europe and Romania. The species composition and population variability in winter hibernacula was examined by using the tools of population genetics (analysis of mitochondrial sequences and nuclear microsatellites). Two hibernacula with exclusive or partial mass representation of soprano pipistrelle were genetically confirmed for the first time. No cytonuclear conflict neither admixed nuclear genotype was detected, that means that early stage of hybridization between both species was not revealed. Similar genetic structure in both genetic markers indicate, that swarming and hibernating populations are substantially overlapping. Compared to the P. pygmaeus, higher genetic variability was found in P. pipistrellus populations, even though genetic variability is relatively low compared to other species. It can be caused by strong gene flow, in the case of P. pygmaeus it may be caused...
