V originále
In Central Europe, greater mouse-eared bats (Myotis myotis) are simultaneously reliant on man (for maternity roosts) and adversely affected by him (landscape destruction) in particular, is often seen as the cause of the decline of many populations. Since most of the endangered bat species of our fauna are synanthropic bats and these are concentrated in periodically monitored roosts (monitoring program of the ANCLP CR and CBCT), we are carrying out a study aimed at the identification of the most important foraging areas around one of the biggest nursery colony in Czech Republic. The investigated nursery usually occupies the attic of the foresters lodge of Ledce (Mladá Boleslav, Czech Republic) from April through September. Numbers have increased from 1700 (adult females) to more than 3200 (with young). Three adults and three juvenile bats were fitted with a transmitter and tracked during July 2007. The transmitters worked from 5 to 12 nights. Fixes were made with two Yagi antennas and receivers. The locations of the tagged bats were recorded throughout the night by two methods (1) triangulation when two mobile workers co-ordinated their movements by hand-held FM radios, and (2) homing-in on a bat. Presence of bats was checked also using a five meters long Yagi antenna on the car roof and a scanning receiver. In case of contact, bearings were taken with the Yagi antenna and a compass. Additionally, every 5 6 km, at vantage points (chosen for their topographical suitability), the car was stopped and fixes were taken. The followed individuals repeatedly returned to the same feeding areas, which can indicate some individual fidelity to these areas. The median distance between feeding areas and the roost was 9 km, being the highest distance recorded 13 km. Young foraged over the field (harvested grain, alfalfa and colza field) and in oak forest more often than adults. Increase in intraspecific competition in deciduous forests, when adult females can use foraging sites in habitats with lower availability of prey and/or distant from their colony roost and relinquish the trophic sites close to the roost to early fledged young. One adult female changed day roost and was even found in other colony, 25 km away from Ledce (Bělá p. B.). Night roosts were visited 1 2 times per night and were found in trees or buildings
