Emil G. Racovitza: Founder of Biospeology, 1962, Motas, C.

The birth of Biospeleology., 1964, Motas Constantin
Modern biospeleology dates from May 15, 1907, with the publication of Racovitza's "Essai sur les problmes biospologiques." In this paper he posed; if he did not answer; every question raised by life in the subterranean world. He outlined a program of biospeological research, made an analysis of the conditions of existence in the subterranean domain and their influence upon cavernicoles, discussed the evolution of subterranean biota, their geographical distribution, etc. Racovitza modified Schiner's (1854) classification, dividing cavernicoles into troglobites, troglophiles and trogloxenes, terms later adopted by a great number of biospeologists. The "Essai", called "Racovitza's famous manifest" by Vandel, was considered the birth certificate of biospeology by Antipa (1927) and by Jeannel (1948), its fundamental statute. Jeannel also made major contributions to the young science through his extensive and detailed studies. The names of Racovitza and Jeannel will always be linked as the uncontested masters of biospeology, the founders of Biospeologica, and the authors of Enumration des grottes visites. Apart from Schiner, whose ecological classification of cavernicoles was utilized and modified by Racovitza, they had another forerunner in Vir, a passionate speleologist who often accompanied Martel in his subterranean explorations, once meeting with a serious accident in which he was on the brink of death. Vir (1897, 1899) studied subterranean faunas, establishing the world's first underground laboratory, where he carried on unsuccessful or ill-interpreted experiments. We consider Racovitza and Jeannel's criticism of him too severe. Let us be more lenient with our forerunners, since their mistakes have also contributed to the progress of science, as well as exempting us from repeating them.

Le peuplement animal des karsts de France (lments de biogographie souterraine pour les invertbrs, premire partie : la faune aquatique), 1987, Ginet R. , Juberthie C.
THE BIOGEOGRAPHICAL DISTRIBUTION OF INVERTEBRATE ANIMALS IN FRENCH KARSTS (FIRST PART: THE AQUATIC FAUNA) - This text analyses the bibliographic data in order to draw up a schematic representation of the biogeographical distribution of Invertebrate animals found in French karsts up to 1985. The animal population of these karsts is very varied, especially in the South of France. For many groups, there are obvious links with geological history and paleo-ecology. This text first lists the aquatic groups (from Porifera to Crustacea; the latter is the most varied and numerous in karstic water). It puts forward possible solutions to the problems posed by the ways followed by the ancestors of present-day groups, either of superficial fresh-water origin, or of marine origin during the Tertiary, and whose areas were later modified by the impact of Quaternary glaciations. For the terrestrial groups (cf. Karstologia n 11), subterranean penetration followed different pathways, among which the Superficial Hypogean Compartment (MSS = Milieu Souterrain Superficiel) plays an obvious role; this shows that many troglobites are not limited, in the underground environment, to just caves and the karst. The Arthropods, and among them the Insects, are of course the most varied and the best known. Their biogeographical distribution reflects the problems of speciation, ecology and endemism, which are discussed in the text.

Laquifre de la source du Lez : un rservoir deau et de biodiversit, 1997, Malard Florian, Gibert Janine, Laurent Roger
The Lez spring is the main source of drinking water for the inhabitants of the city of Montpellier. This spring has been exploited since the eighteenth century but the amount of groundwater pumped has markedly increased over the last 30 years. This karst harbours an extremely diversified community of groundwater species (at least 37 species) that is a several Million-year-old heritage. Overpumping induces a loss of habitats by lowering the water table during periods of low groundwater recharge. It also results in an artificial fragmentation of mesohabitats by increasing the hydraulic disconnection of different regions in the saturated zone. Thus, overpumping may strongly affect the groundwater fauna but few data are available yet to evaluate the potential loss of biodiversity. There is clearly a need to integrate studies of groundwater fauna within the framework of interdisciplinary groundwater monitoring, management and/or protection programmes.

Les mollusques souterrains du rseau karstique de Padirac (Lot, France) et micro-rpartition de Bythinella padiraci Locard, 1903 (Mollusca, Caenogastropoda, Rissooidea), 2004, Bichain Jeanmichel, Boudsocq Christian, Pri Vincent
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 Dversoir 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.
