Transport and variability of fecal bacteria in carbonate conglomerate aquifers, , Goeppert N. , Goldscheider N.

Clastic sedimentary rocks are generally considered non-karstifiable and thus less vulnerable to pathogen contamination than karst aquifers. However, dissolution phenomena have been observed in clastic carbonate conglomerates of the Subalpine Molasse zone of the northern Alps and other regions of Europe, indicating karstification and high vulnerability, which is currently not considered for source protection zoning. Therefore, a research program was established at the Hochgrat site (Austria/Germany), as a demonstration that karst-like characteristics, flow behavior and high vulnerability to microbial contamination are possible in this type of aquifer. The study included geomorphologic mapping, comparative multi-tracer tests with fluorescent dyes and bacteria-sized fluorescent microspheres, and analyses of fecal indicator bacteria (FIB) in spring waters during different seasons. Results demonstrate that (i) flow velocities in carbonate conglomerates are similar as in typical karst aquifers, often exceeding 100 m/h; (ii) microbial contaminants are rapidly transported towards springs; and (iii) the magnitude and seasonal pattern of FIB variability depends on the land use in the spring catchment and its altitude. Different ground water protection strategies than currently applied are consequently required in regions formed by karstified carbonatic clastic rocks, taking into account their high degree of heterogeneity and vulnerability.

Duration of the molts and intermolts of adults and the life span of Stenasellus virei Dollfus (troglobe Asellote Crustacean)., 1971, Magniez Guy
The author's observations of numerous cases of molting in the hypogean asellid Stenasellus virei Dollfus, 1897 appear to show that the phenomenon occurs in two steps. The loss of the anterior exuvium is separated from that of the posterior exuvium by a period of 8 to 16 days in adults from cavernicolous populations of Stenasellus virei in the Pyrenees and Cantabrian Alps. The intermolts last from 9 to 18 months for the same individuals. One must allow, for this species, a minimun life span of 10 years. Values of the same order of magnitude are anticipated for the two other Pyrenees species, Stenasellus breuili Racovitza, 1924 and Stenasellus buili Remy, 1949. These observations agree with those previously made on other cavernicolous peracarid crustaceans, such as Caecosphaeroma burgundum Dollfus and Niphargus virei Chevreux, by Daum (1954), Husson (1959) and Ginet (1960).

A cavernicolous Japygidae Diplura from Corsica, Dipljapyx beroni n.sp., 1974, Pages Jean
Dipljapyx beroni n.sp. has been collected from two caves in Corsica. From its antennae with 31 articles, chaetotaxia of urites and subcoxal organs well-characterized, it appears to be an endemic Corsican species, situated between D. humberti Grassi found in the western Alps, and D. italicus Silv. peculiar to the Italian Peninsula. It is closely related to the first of those two species. There is no morphologic feature indicating it as a troglophilic species.

The adaptations to volvation of the external cephalic skeleton of Caecosphaeroma burgundum Dollfus, a subterranean waters Isopod., 1976, Marvillet Claude
The study of the cephalic capsule of Caecosphaeroma burgundum, a subterranean waters Isopod, demonstrates improved adaptations to volvation; these concern in a similar manner the other regions of the body, particularly the pleotelson. From a primitive aquatic Isopod structure, the head of this blind Spheromid has been completely fashioned by many mechanical factors: posterior margin of pleotelson providing support on the head, relation of anterior angles of the second pereionit and, above all, the mandibular palps and antennae which retract into two deep grooves of the face. The comparative study of the head of other volvational Isopods shows the importance of that "antennary factor", e.g. in Oniscoids, epigean Spheromids and some other subterranean waters Isopods (two Spheromids and one Cirolanid). This comparison shows that Caecosphaeroma burgundum is certainly the most specialized of all; it approaches perfection in volvation for it is the only one which rolls up into a hermetic sphere without outwards projections. Volvation seems to play a two-fold role. It is a mean of defence against predators used by single specimens and by copulating pairs, males and females being then associated in two concentric spheres. Furthermore, it is a very important way for passive dissemination allowing settlement of these Crustacea in distant subterranean waters.

A study on Rhachomyces species (Ascomycetes, Laboulbeniales), parasitic on Italian Duvalius (Coleoptera, Carabidae, Trechini)., 1978, Rossi Walter
The systematic position, variability and distribution of the two species of Rhachomvces parasitic on Italian Duvalius are defined on the basis of several new findings. Rhachomyces stipitatus Thaxter was found in Liguria, central Italv, Sicilv and Sardinia; its synonyrny with R. capucinus Thaxter is confirmed and the ssp. pallidus Maire is considered of no systematic relevance. R. maublancii, whose position is regularized by a Latin validating diagnosis, was only found on the Alps and previous records in other countries are questioned.

Hydrologie du lac de Lessy (Haute--Savoie), 1983, Sesiano J. , Muller A.
SOME HYDROGEOLOGICAL OBSERVA-TIONS IN LAC DE LESSY (Haute-Savoie, France) - Located in the French Prealps near Annecy, lake Lessy is a 70,000m3 body of water, at an altitude of 1800m. a.s.l., in a karstic area. It has no visible outlet. A dye tracing was made during september, 1981, in order to identify which spring in the valley is fed by the lake. The experiment was successful: a strait distance of 3.5 km was covered underground in about 15 hours. It also appeared that the major part of the water flowing from this spring does not come from the lake, but from the surrounding plateaus

Hydrogologie karstique des Alpes-Maritimes, 1984, Baissas, P.
Karst hydrogeology in the Alpes-Maritimes - In the Marguareis, the systems penetrate very quickly by transverse faults, to reach the impermeable basement and then follow the dip. All the waters, even those on the French side, belong to the P basin. In the Roya arc, underflows are to be found going round the base of the Argentera-Mercantour. In the Nice arc, the karstification depends principally on tectonic factors and according to the places, the water follows either the overlaps or transverse faults. In the Grasse plateaus, the galleries follow at the outset the slopes and the dips of the synclinal hinges; the tectonic factors determine the location of the resurgences ; at depth, the karst is always phreatic, with relations between tectonic compartments during floods. In the cover of the Tanneron-Esterel basement and Barrot Dome, lithological factors determine flow.

Le rle des hritages quaternaires dans les karsts alpins : le cas des Alpes du Nord, 1984, Chardon, M.
THE PART OF THE QUATERNARY INHERITED FEATURES IN THE ALPINE KARSTS: THE EXAMPLE OF THE NORTHERN ALPS - In the western part of the Alps, limestone mountains have been built mainly during Miocene and Pliocene. The relicts of pre-quaternary alterations or karstifications are scarce and difficult to identify. The most part of the morphological features can be related to the quaternary glacial stages. The main landforms of the high and low alpine mountains are described. The glaciers and their melting waters have excavated deep gorges-valley and caves.

Le Vercors : un massif de la moyenne montagne alpine, 1984, Delannoy, J. J.
THE VERCORS: A MASSIF OF MIDDLE ALPINE MOUNTAIN - The Vercors is a forested massif of middle mountain, in the French Northern Prealps. The characteristic of the Vercors massif is the thick and massif urgonian limestones, which underlines a folded structure. The Vercors quickly hold the attention of speleologists, who had put forward the density and diversity of karstic aspects since the beginning of the century. Landforms display glacial karstic landscapes more or less damaged in terms of bio-climatic levels of mounts and depressions landscapes and of deep water gaps, which main flows of the massif are flowing in. The notion of the morphoclimatic heritage applies to the underground karst for which glacial quaternary episodes have been determinant in the large systems genesis (gouffre Berger - Scialet de la Fromagre, Antre des Damns, Combe de Fer...). The study of underground deposits allows to bring up-to-date various period of karst development; a preglacial stage (e.g. upper levels of Cuves de Sassenage, Gournier, Coufin-Chevaline...). The study of the current dynamic shows that the Vercors as an important karstic ablation, between 120 to 170mm/ky. The karstic dynamic exerts mainly on the superficial slab of the massif (from 80 to 50% of the whole ablation). The Vercors can be considered as the best example of calcareous massif in temperate middle mountains, thanks to the combination of various favourable parameters: pure karst rocks, morpho-climatic episodes not constraining, and a high karstic dynamic.

Les grandes cavits alpines, 1984, Delannoy J. J. , Maire R.
THE LARGE ALPINE CAVES: DISTRIBUTION AND HYDROGEOLOGICAL CONTEXT - Western Alps possess about 40 caves deeper than 500m. The large karstic systems are situated principally in the external alpine zone (subalpine ranges) and secondly in the internals alpine zone (Marguareis). These caves develop in different structural patterns (perched syncline, anticline...). The vadose zone is characterised by a vadose circulation, the phreatic zone has a diverse importance, depending on geological structure.

Les palokarsts des Alpes occidentales du Trias l'Eocne, 1984, Guendon, J. L.
WESTERN ALPS PALEOKARSTS FROM TRIASSIC TO EOCENE - In western Alps, before complete emersion during the Oligocene and Miocene, the marine sedimentation has been locally interrupted by three important continental phases: 1/ during Early Jurassic, in "brianonnais" domain; 2/during middle Cretaceous, in Provence area; 3/ during early Tertiary, in subalpine range and Jura. These locally and temporary regression are the consequence of tectonic activities in relation to the movements of eurasiatic and italo-african plates, which are at the edge of the alpine oceanic basin (Tethys). After an abstract on the tectonic and sedimentological history of western Alps, a description is given of continental formations (bauxites, fire-clay, clay with flints, siderolitic formations, white and ochrous sands, siliceous and ferruginous crusts) and karst phenomena elaborated during these regressions.

Le rle des hritages quaternaires dans les karsts alpins : le cas des Alpes du Sud, 1984, Julian, M.
THE PART OF THE QUATERNARY INHERITED FEATURES IN THE ALPINE KARSTS: THE EXAMPLE OF THE SOUTHERN ALPS - The periglacial past-processes influenced karst landforms. 1) the paleoclimatical change (Wrm) related to the present climatical parameters; 2) the impact of periglacial processes on the superficial karst; 3) the internal evolution of the karst during the cold phases.

Karsts alpins et notectonique, 1984, Julian, M.
ALPINE KARSTS AND NEOTECTONIC: A BRIEF OVERVIEW - Several problems are studied at the light of new investigations: 1) the deepening of the karstic network related to orogenic uplifts and the corresponding levels of the caves; 2) the tectonic deformations (faults) described upon some karstic surfaces or into some caves; 3) the pseudo-tectonic deformations like toppling failures and other tension-cracks parallel to the vertical cliff faces.

Un karst subalpin mditerranen : la rgion Audibergue-Mons (Alpes-Maritimes et Var), 1984, Julian M. , Nicod J.
THE KARSTIC AREA AUDIBERGUE-MONS (Prealps of Grasse, Maritime Alps and Var departments) - This area, very important for the karstic superficial features and the caves, is formed by the proximity of plateaus belonging to the structural system of Provence and the higher main subalpine unit of Audibergue. Three fields of sinkholes are especially characteristic: 1/ central Audibergue, controlled by shear fractures and under the influence of nival phenomena; 2/ Fort d'Esclapon, with more various forms and perhaps an older karstic evolution that explains the large inheritance of terra rossa; 3/ Biron that shows deep furrows and sinkholes. The study of the poljes, fluvio-karstic (Caille) or half-opened (Canaux), introduces the problem of the underground karstic hydrology. The dynamics of neotectonics and morphoclimatic systems, specially the old periglacial processes, is considered with reference to the main forms and deposits shown on the map.
