Ecology of Fonticola notadena de Beauchamp (Turbellaria, Triclade) in the La Balme cave (Isre, France); suvival in a dry period., 1964, Ginet Rene, Puglisi Rodolphe
During many months a year the acquatic Planaria (F. notadena) living in a small pool in the La Balme cave are subjected to a drought with the complete drying out of their biotope; they support in situ this lack of water and, living in a latent way inside the clayey matrix. Thanks to the great hygroscopy of the clay, enough humidity stays around the Planarians to enable them to survive. During this period the Planaria may undergo spontaneous divisions resulting in their asexual multiplication.

Remarks on the species Asellus cavaticus Leydig (Hypogean Isopod Crustacea) and description of new sebspecies., 1966, Henry Jean Paul
In Europe, Asellus cavaticus Leydig until 1963 was the only species known of a phyletic line that extended from Britain to Austria. Until the works of Racovitza in 1919 all the Asellus of the underground world were reported to this species, first known subterranean Asellus. The taxonomic criteria of Racovitza allowed to determine many subspecies. Later on Chappuis refuses to give names to the different encountered forms. Taking as type forms the individuals of the grotte de Sainte-Reine (Meurthe-et-Moselle), considered very similar to the original type forms, we think to be able to define a new subspecies puteanus for the Asellus of a well in Beaujolais. This form differs from cavaticus f. typ. for the form of the male copulation organ, the male pleopod and the number of spines on the dactlya and pereiopodes. A more detailed description of the subspecies valdensis Chappuis is given based on specimens from a cave of the Plateau of Crmieu (Isre).

Le systme souterrain du Sornin (Berger-Fromagre, Vercors, Isre), 1983, Delannoy, J. J.
THE UNDERGROUND SYSTEM OF PLATEAU DU SORNIN (VERCORS, FRANCE): THE GOUFFRE BERGER AND THE SCIALET DE LA FROMAGERE - Gouffre Berger (-1198m) and Scialet de La Fromagre (-902m) are the two main drains of an important underground complex, which develops 26 km inside Sornin table-land, massif du Vercors, Isre. The glaciers have left deep prints in the surface morphology (Schichttreppenkarst) and have played an important role in the genesis of the underground complex of Sornin. Most of morphological elements and dated witnesses (speleothems) testify to the primacy of this morphoclimatic term. Under present bioclimatic conditions (discontinuous forest - Raw weather climate, T? = 4?C, P = 1700mm), the specific dissolution is estimated to 120mm/ky. This dissolution is important in winter (2,5 times more than in summer). Sornin plateau belongs to an intermediary case between forests mountainous karsts and high karsts regarding the spatial distribution of the dissolution.

Le systme souterrain de la Dent de Crolles, Isre, 1985, Marchand, Th.
THE UNDERGROUND SYSTEM OF DENT DE CROLLES (ISERE, FRANCE) - The Dent de Crolles plateau (highest point: 2062m asl.) is the southermost part of the great syncline of the eastern Chartreuse. This syncline stretches from Grenoble to Mont Granier, above Chambery. The karst of Dent de Crolles develops in urgonian limestone, and in spite of little surface (2km2), it contains the most important underground system of the French Alps (about 52km). In spite of important oceanic rainfall, underground flows only drain some small galleries. Karst genesis is related to the glaciers.

Le karst du massif Moucherotte / Pic Saint-Michel (Isre, Vercors), 1991, Audra, Ph.
The karst of Moucherotte/Pic Saint-Michel (Vercors, Isre, France) - The massif of Moucherotte-Pic Saint Michel is located in the northeastern corner of the Vercors, in the area of Lans-en-Vercors and Saint-Nizier-du-Moucherotte. As anywhere in Vercors, this area is strongly marked by a dense karst relief. It harbours underground systems. Recent dye tracings (respectively from Sierre shaft, Choucas shaft, and Ira's Hole) allowed to determinate precisely the boundary of the catchment of the source called Bruyant. This basin spreads out from the Moucherotte to the Pic Saint-Michel, thus including a surface of 12km2. This is confirmed through the water balance. Of the 1600mm of yearly rainfall, 70% is infiltrated toward the source of the Bruyant. The water is conveyed through a main drain, probably mostly vadose, at the base of the recumbent fold. The landscape is due to the Quaternary processes. The two great landslides of "col de l'Arc" and of "Peuil" date back to this time. The glaciers have sculptured huge "combes" where many caves open, ancient places where sub-glacial waters were swallowing. These sub-vertical caves (which can measure up to 300m deep) with shafts and meanders, flow through large horizontal galleries older than the Quaternary (Combe Oursire shaft, Vallier cave). These galleries, hidden away in this huge limestone mass, are the witnesses of an earlier and very elaborate subterranean drainage. This system is entirely different from our present drainage system.

Mesure de la propagation dune perturbation de pression au Trou qui Souffle (Maudre, Isre), 1993, Lismonde, B.
The Trou qui Souffle (Breathing Pot) is a cave in Vercors. There are three entrances, two of which are known and are situated 2 km apart. With one entrance rapidly obstructed, the effect upon the velocity of wind was measured at the other. The findings were a speed of about 100 m/s

Les apports de lendokarst dans la reconstitution morphognique dun karst ; exemple de lAntre de Vnus (Vercors, France), 1998, Delannoy Jeanjacques, Caillault Serge
The whole of the informations which can be found in the endokarst gives a better knowledge of the hydrogeologic, geomorphologic, tectonic and climatic evolution of a calcareous mountain mass. However, the study of the cavities is not yet developed or integrated in the karst studies. The objective of the present work is to show the interest of such a proceeding by the study of a cavity in the northern Vercors : "Antre de Vnus". From the simple observation of the shapes, the deposits and their relation, a speleogenic reconstitution of this cavity and, mainly, of the environment, is proposed.

Quelques aspects des conditions de circulation des eaux souterraines dans les karsts du gypse des Alpes internes, 1999, Couturier Bernard, Fourneaux Jeanclaude, Sommeria Laure
The Triassic gypsum outcrops are widespread, in the French Inner Alps. They are often found in large heaps between two structural units. Karstic landforms with sinkholes and collapse zones are visible even when they are covered with glacial deposits or fallen rocks. There is also much evidence of underground flows, but the springs do not have any karstic characteristics. The water tracings (two examples) show that the local tectonics have a great influence in the subterranean circulation conditions. At "La Norma" in the Arc valley (Maurienne) the water infiltrated in a large sinkhole supplies several small springs after transit in a fissured aquifer. The spring flow is well regulated. At "Le Clou" in the upper Isre valley (Tarentaise) several sinkholes with loss of ephemeral streams during melting snow supply a large fissured aquifer. There is no spring with karstic features either. The water infiltrated in a sinkhole has been found in several springs during a very long period of time. Whereas the upper part of these aquifers are really like a karstic aquifer, with large stream channels, on the contrary the deeper part is like a fissured aquifer with large water dispersion and low velocity. The fissured and porous aquifer has a throttling action and explains the absence of true resurgence. The underground water flow is unbroken between the different aquifers but permeability decreases according to the depth. These phenomenon are in connection with tectonic activity and the interpenetration of the different geological formations at the bottom of the gypsum layer.
