The evolution of faunal composition in a subterranean cavity of simple structure (Trou des Nutons, Chaudfontaine, Belgium) has been studied. Quantitative comparisons have been carried on in the two most important parts of the cave - the external zone and the deep zone - using diversity and similarity coefficients. It has been found that the external zone presents a great redistribution of the fauna while the deep zone is more stable. However, the whole cave community stays relatively constant during time.
