Abstract

The climate usually changes with the change of altitude. That change affects all living organisms, including bats. With this research we wanted to see if there is a change in species composition and sex ratio within the species with gradual altitude change from 0 to 680 m above sea level and if there are any alterations as the season changes. We also wanted to get data for bat activity at different altitudes and its connection with microclimatic conditions. Species richness didn’t decline with the increase of altitude, but there was a difference in species composition caused by different habitats, although the biggest number of caught bats was in the middle of the altitudinal range. Bats were most active in a period when the temperature wasn’t at its highest, so it wasn’t a limiting factor. Overall, the number of caught bats was smaller than during all of the previous researches, which was probably caused by an unusually cold and rainy season.
