According to Krizler Tanalgo, "DarkCideS 1.0" is by far the largest database for cave-dwelling bats. "It contains various datasets for at least 679 bat species around the world. The database currently contains 6746 georeferenced occurrences for 402 cave-dwelling bat species from 2002 cave sites in 46 countries and 12 terrestrial biomes." The database has been developed to be collaborative and open-access, allowing continuous data-sharing among the community of bat researchers and conservation biologists to advance bat research and comparative monitoring and prioritisation for conservation.
The database can be accessed on this website:
The results are published in Nature's Scientific Data:
