Results of Research on the Bat Fauna of the Vârghiş Gorge (Eastern Carpathians, Romania)
2007
During the period between 2000 to 2004 in the Vârghiş Gorge (Eastern Carpathians, Romania) 23 caves were checked in order to collect chiropterological data. In 16 of them bats or bone materialwere found. Check-up of caves, netting and detectoring were used as methods and the collected bone material was also determined. 17 bat species were identified. The results suggest that
Distribution and conservation status of cave-dwelling bats in the Romanian Western Carpathians
The limestone regions of the Pădurea Craiului, Bihor and Trascău Mountains are home to the largest and most important bat aggregations in Romania. In the last few decades only sporadic information on cave-dwelling bat fauna of the regions was published, with no large-scale studies undertaken. The present study is meant to fill this information gap. Between 2010 and 2012 we visited 60 caves, located in the territory or in the close proximity of six Natura 2000 sites. Data collection was done during the summer and winter periods, with the identification of resident bat species, and estimation or counting of large aggregations. In the study area we found two thirds of the 31 species of the Romanian bat fauna.
Bats hibernating in the natural caves in the Polish part of the Sudetes
Przyroda Sudetów Zachodnich, Suplement, 2002
In three winter seasons (1999/2000, 2000/2001, 2001/2002) 26 caves in the Polish part of the Sudetes were investigated and 13 bat species were found: Myotis myotis, M. bechsteinii, M. nattereri, M. emarginatus, M. mystacinus, M. brandtii, M. dasycneme, M. daubentonii, Eptesicus nilssonii, E. serotinus, Plecotus auritus, Barbastella barbastellus and Rhinolophus hipposideros. M. myotis and M. mystacinus/brandtii were the dominant species (27.3% and 24.4% of all identified bats, respectively). M. daubentonii (18.9%) and M. nattereri (10.7%) were relatively abundant. B. barbastellus and P. auritus represented 8.3% and 8.6% of all bats. The largest hibernacula were Niedzwiedzia Cave near Kletno (with max. 251 individuals in 2002) and Szczelina Wojcieszowska Cave in Polom near Wojcieszów (max. 194 ind. in 2001). They seem to be the most important winter localities in the Polish part of the Sudetes for M. mystacinus/brandtii (max. 132 ind.), M. myotis (102 individuals), M. daubentonii (max. 59 ind.), P. auritus (max. 33 ind.) and M. emarginatus (max. 7 ind.). Single individuals of M. dasycneme were found in caves in Polom. In Na Scianie and Nad Ladkiem caves Rh. hipposideros were recorded for the first time in the winter of 2002. The caves are very important hibernating places for bats, but more winter localities in the Sudetes are located in old mines. The number of bats hibernating in the Polish part of the mountains is lower than in hibernacula in the Czech part, where there are several localities with nearly 300-1300 individuals and a greater number of rare species.

Optimum climatic conditions from the Gura Ponicovei Cave allowed the temporary sheltering of 15 bat species, only in hibernation colonies, or only in nursery colonies, or in both of them succesively: 4 rhinolophids and 11 vespertilionids.

Bat fauna and conservation assessment of Kurdistan caves, Iran
Subterranean Biology, 2022
The populations of cave-dwelling bat species are encountering a remarkable decline all over the world. To plan effective conservation projects for bats and their cave roosts, collecting data on their distribution in a particular region is essential. Furthermore, developing an applicable index that incorporates both biotic and abiotic parameters relevant to caves is useful to prioritize caves for conservation management. Recently, there has been a growing interest in studying bat fauna of Iran. The Kurdistan province in west of the country is entirely mountainous, having a suitable geological substratum for formation of caves. Previously, five bat species were reported from Kurdistan. The current study has improved the data by doubling the number of cave-dwelling bat species of the province. A total number of 61 records of 10 species were documented. Overall, of 28 caves studied, 26 caves were used by bats. Each cave hosted one to six bat species. To prioritize Kurdistan caves for co...

Cave Dwelling Bat Species and their Cave Preferences in Northwest of Central Anatolia
Cave Dwelling Bat Species and their Cave Preferences in Northwest of Central Anatolia, 2019
Many of the cave-dwelling bat species are under threat, because of destruction of caves such as filling or converting for other uses, human disturbance and loss of foraging habitats. In this study, cave-dwelling bat species and habitat preferences were investigated in Northwest of Central Anatolia in spring, summer and winter. Investigations were performed in 26 caves hosting (15) and not hosting (11) bats. Temperature, humidity, length of caves, distance to nearest settlement, paved road, water source, agricultural area; height, width and orientation of cave entrance and activity of cave values were determined. Seven out of 10 recorded bat species were evaluated as new records for the area. There was a significant preference for caves which were situated at lower altitude, far from paved road and close to water source. Bats were mostly found in longer caves. Caves with entrance oriented to northwest and southeast were preferred by bats. Undertaking effective conservation measures to maintain especially eight threatened bat species which were found in the region should be a priority for conservation management plans.
