Preliminary data on bat species hibernating in Cupcini and Hordinesti stone quarries in Hordinesti quarries. Immediately after the entry into quarries, at about 3-5 m, the first specimens of bats were found. The individuals were found solitarily or in groups in cracks, niches, on the edges of ceiling, in the corners and just hanging from the ceiling. Only two species formed groups: M. blythii was observed in groups of 2 to about 30 individuals (fig. 1) and M. daubentonii was found in small groups of 2—4 individuals. Other species were found exclusively solitarily. Near the entrances in quarries, at 3-4 m, were observed the first individuals of M. blythii and of Plecotus genus species. The Plecotus species prefer to hibernate near the entrances of underground roosts, it was found between the distance of 3 up to 12 m, while the lesser mouse-eared bat was found near the entrances, as well as deeper in the underground up to 100-120 m. The community structure and species dominance was different in the studied mines (fig. 2). Thus, in Cupcini mines the most numerous were M. blythii with 86.33%, followed by M. daubentonii with 12.58% and M. mystacinus with 1.09%. In Hordinesti quarries the most numerous were M. daubentoni with 84.62%, followed by M. blythii (11.92%), while the rest of species were registered in low number (Rh. hipposideros — 0.77%, P austriacus— 1.54%, P auritus - 1.15%). The dominance index (Naughton-Wolf) of M. blythii in Cupcini mines was of 0.99 and of M. daubentoni in Hordinesti mines was of 0.96 that shows the absolute dominance of the respective species in hibernating bat communities from the studied quarries. Fig. 2: Community structure of bats hibernating in Cupcini (A) and Hordinesti (B) underground roosts According to the Zoogeographie origin all registered bat species belong to different areas of Palearctic zone (tab. 1). After the criteria of rarity all the species found in both locations are included in Annex II of Bern Convention, in EURO BATS agreement, in the Red Book of Moldova, 3rd edition, and in the Red Book of Vertebrates from Romania with various category of rarity - vulnerable, endangered or critically endangered (tab. 1).
