Bats of the genus Plecotus in the fossil record of central and SE Europe.
Balážová, Alena ; Horáček, Ivan (advisor) ; Hanák, Vladimír (referee)
In this thesis a review and detailed morphometric analysis of fossil material of genus Plecotus Geoffroy, 1818 (Microchiroptera) from central Europe from miocene till recent was done. Both metric and phenetic features of skull ant teeth were compared with recent european species of this genus. The most detailed attention was focused on fossil species Plecotus abeli Wettstein-Westersheim 1923, which is most likely only an extreme phenotypic variety of Plecotus auritus group. Fossil record from Karlukovo (Bulgaria) was studied too. The first record of Plecotus macrobullaris Kuzjakin, 1965 was found there.

Population and geographic variation in long-winged bats (Miniopterus) in the western Palaearctic
Šrámek, Jan ; Benda, Petr (advisor) ; Hanák, Vladimír (referee)
In this study the sexual and geographical variations in the genus Miniopterus were deeply investigated, using multidisciplinary analysis (morphometric cranial, dental, fenetic and shape analysis; molecular analysis of mt gene ND2). Different populations from western Palearctic and adjacent regions were analysed: Miniopterus schreibersii (Morocco, West Europe, Pannonia, Balkans, Crete, Near East, Middle East), Miniopterus natalensis (Yemen, Ethiopia) a Miniopterus inflatus (Ethiopia). Extensove samples of Miniopterus schreibersii were tested and existence of sexual dimorphism in cranial constitution was showed: males had generally bigger and relatively higher, shorter and narrower skulls than females; female mandibles were generally bigger than the male ones, females showed also more robust and larger teeth than males. On the other hand, males had markedly bigger canines and relatively higher P4 (in relation to other premolares). The sexes also deiffered in shape of P4 and upper molars. According to the interpopulation variation found, Miniopterus schreibersii samples from West Europe, Pannonia, Balkans, Crete, Sicily, Georgia, coastal Turkish and Moroccan areas belong most probably to the subspecies M. s. schreibersii (Kuhl, 1817). The samples from Afganistan, Iran, Azerbaijan, and from localities...
