Abstract:
Subterranean molluscs of the karstic network of Padirac (France, Lot) and micro-distribution of Bythinella padiraci Locard, 1903 (Mollusca, Caenogastropoda, Rissooidea) - During a Padirac expedition in November 2003, about ten biological samplings were carried out in the deep karstic network. The first aim of this biospeological mission was to update the data on stygobites molluscs in this subterranean ecosystem. The results show that Bythinella padiraci Locard, 1903, species listed as vulnerable in the 2004 IUCN world Red List of threatened animals, although absent in the upstream part of the Padirac subterranean river, is present in its downstream part after the Déversoir and in the De Joly affluent. An hydrobioid belonging to the genus Islamia was recorded as a component of the stygobiontic biocenose of Padirac as well as Moitessieria rolandiana Bourguignat, 1863. In addition, 3 epigean freshwaters molluscs were observed alive in the deep network, Potamopyrgus antipodarum, Ancylus fluviatilis, Pisidium sp. as well as a terrestrial mollusc, Discus rotundatus.
