crevice-type caves, bats, microclimate of caves

Microclimate of crevice-type caves (CRCs) of the Moravskoslezské Beskydy Mts predisposed to wintering of bats. Long-term temperature and humidity observations demonstrate habitat conditions suitability to bats occurrence. Dynamic thermal regime is observed in parts related close to the outside e.g. by narrow crevices or close to the entrance. Temperature in these parts is influenced by outside conditions.
