The climatic study of caves with single entrance: temperatures, humidity, thermal exchanges

A vast scientific literature describes the ventilation mechanisms of these caves and the consequent thermal variations. Conversely, the lack of appreciable air circulation is considered by cavers as a clue to not extended cave, i.e. not interesting. However, from the biological point of view, in NW Italy the caves with single entrance are the most interesting: their more protected environment host many more endemic species. This work presents the dynamics and the study method of several cave with single-entrance of NW Italy
