Intraspecific variability of populations of two cryptic bat species of genus Pipistrellus in Central Europe

GAČR 206/02/0961

The submitted project is a follow-up on the previous project funded by a grant of GAČR (No. 206/02/0961) which focused on interspecific differences in the distribution of two cryptic species – Pipistrellus pipistrellus and P. pygmaeus – within the Czech Republic. Achieved results suggest intraspecific variability of genetic characters as well as echolocation parameters and ecological requierements. Hitherto, this variability has not been studied in the cryptic species of the genus Pipistrellus. The aim of the proposed project is to get an understanding of the life history of both cryptic pipistrelle species including the mechanisms of development of ecological and behavioural adaptations. Based on intraspecific variability the probability of character displacement will be studied within sympatric populations in the area of the Czech and Slovak Republics. Methods of molecular ecology (microsatellites, mtDNA gene ”cyt b”) as well as analyses of echolocation signals and ecological requierements will be used.
