Teza

The studies were conducted from August 2014 to April 2015 in abandoned stone quarries of Cricova town, in order to determine the species diversity of bats. The mines represent a limestone complex of hand and machine processing. The microclimate formed in the quarry is favorable for the development of many bat species. The depth of mines is of 200-300 meters and the total length of the galleries reaches two kilometers. Temperature throughout the year oscilates aroud 8oC and the humidity is of 45%. During the study of the quarry species studiy was carried out by collection and examination of animals and their identification according to the field guide, also using ultrasonic detectors that register echolocation signals. The number of bats in this quarry is small and the distribution is uneven throughout the year. Most of bat individuals were found in the period from November to March, while during the summer months have been found just a few individuals (fig.1). Figure 1. The number of bats in the Cricova stone quarries (August 2015 - April 2016) The maximum number of bats for the entire period of observation found in the period from January to February was of 51 individuals. To determine the preferred temperature, humidity and air flow circulating in a quarry, on the map were marked the places, where the object of study was recorded (fig. 2). Rhinolophus hipposideros – red dots Myotis mystacinus – yellow dots Myotis bechteinii – blue dots Myotis daubentonii – dark blue dots Myotis dasycneme – green dots Figure 2. Zone of evaluation and determination of bats’ location in Cricova stone quarries Therefore, the lesser horseshoe bat (Rhinolophus hipposideros) prefer quiet places, withour air flow and temperature fluctuations and with the warm and stable conditions, while some species were found at the entrance to the mines. In general, the dominant species in the mines is Daubenton’s bat (Myotis daubentonii), followed by the pond bat (M. dasycneme), lesser horseshoe bat (Rh. hipposideros), bechstein’s bat (M. bechsteinii) and the whiskered bat (M. mystacinus). Such species composition can be explained by the close proximity of water resources, which is the main factor for the life of these species. Brown long-eared bat (Plecotus auritus), Grey long-eared bat (P. austriacus) and serotine bat (Eptesicus serotinus) were detected extremely rare. The uneven distribution of bats suggests favorable conditions for the winter, but in the warm season, bats are moving into places richer in food resources. Thus, in Cricova mines the number of bats is low and for the most part these are solitary individuals but, despite this, here can be found a great diversity of chiropteran species in the central zone of the Republic of Moldova. The work was performed within the fundamental project 15.187.0211F at the Institute of Zoology of A.S.M.
