Speleothems and paleoglaciers, , Spotl Christoph, Mangini Augusto,
Ice and speleothems are widely regarded as mutually exclusive as the presence of liquid water is a fundamental prerequisite for speleothem deposition. Here we show that speleothems may form in caves overlain by a glacier, as long as the temperature in the cave is above freezing and the conduits are not completely flooded by melt water. Carbonate dissolution is accomplished via sulfide oxidation and the resultant speleothems show high [delta]13C values approaching and locally exceeding those of the parent host rock (lack of soil-derived biogenic C). The [delta]18O values reflect the isotopic composition of the melt water percolating into the karst fissure network and carry an atmospheric (temperature) signal, which is distinctly lower than those of speleothems formed during periods when soil and vegetation were present above the cave. These `subglacial' speleothems provide a means of identifying and dating the former presence of warm-based paleoglaciers and allow us to place some constraints on paleotemperature changes

Recharge of Phreatic Aquifers in (Semi-)Arid Areas, ,
Groundwater use is of fundamental importance to meet the rapidly expanding urban, industrial and agricultural water requirements in (semi) arid areas. Quantifying the current rate of groundwater recharge and define its variability in space and time are thus prerequesites for efficient groundwater resource managment in these regions, where such resources are often the key to economic development. Attention focuses on recharge of phreatic aquifers, often the most readily-available and affordable source of water in (semi) arid regions. These aquifers are also the most susceptible to contamination, with the recharge rate determining their level of vulnerability. (Semi) arid zone recharge can be highly variable, the greater the aridity, the smaller and potentially more variable the natural flux. Its determination is an iterative process, involving progressive data collection and resource evaluation; there is also a need to use more than one technique to verify results. Direct, localised and indirect recharge mechanisms from a spectrum of known sources are addressed in the framework of recharge from precipitation, intermittant flow and permanent water bodies. The approach taken for each of these reflects the nature and current understanding of the processes involved. The volume also reviews current recharge estimation challenges, outlines recent developments and offers guidance for potential solutions.

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.

A Hypothesis for the Formation of Rimstone Dames and Gours, 1965, Varnedoe, Jr. , William W.

The ecological classification of cave and fissure water in the underground water habitats., 1967, Husmann Siegfried
Bodies of waters in caves and in crevices of rocks are distinguished from the other subsoil water ecosystems ("eustygon", "stygorhithron", "stygopotamon") under the names "troglostygon" and "petrostygon". The colonisation of subsoil water biotopes involves a fundamental principle which controls the development of the main biotopes for the stygobiont undergroundwater organisms. According to this ecological rule, which is described in detail and formulated, the several interstitial biotopes (for example "eustygopsammal," "rhithrostygopsammal," "potamostygopsephal") are to be considered as the real biotopes of the stygobiont subsoil water organisms; waters in caves, on the contrary, are secondary biotopes of these animals. Caves which contain marine water are described as ecostystem "Thalassotroglon" in their relation to "limnotroglon" (= "stygotroglon"). In this why the contact between "limnospeology" and "thalassospeology" is established, and the limnic and marine microcavernal biotopes; "thalassopsammal" and "thalassopsephal"; are also taken in consideration. "Limnospeology" and "thalassospeology" as limnological and thalassological investigations of subsoil water are characterized as biological fields of work, which serve for the investigation of an ecological unit.

Alignment of dolines north-west of Lake Constance, Germany, 1968, Matschinski M. ,
An account is given of the karst features of a given area, and ways of finding some order in their apparently chaotic arrangement. The simplest characteristic to study is the alignments of the karst features. These can be determined either subjectively (following the simple overall impression given by the area), or objectively (on the basis of various mathematical or graphical operations). A distinction between 'local' and 'general' alignment by an elementary statistical-graphical method is proposed. This method is applied to the Lake Constance area, and the results are interpretated in relation to the geological features of the area. It is concluded that (a) the structural features of an area have a strong influence on the karst phenomena, and (b) there is a possibility of revealing, and even making geometrical determinations of, some geologically fundamental directions, e.g. tectonic--from an analysis of the distribution of such relatively superficial phenomena as karst features

The Origin and Development of Mullamullang Cave N37, Nullarbor Plain, Western Australia, 1970, Hunt, G. S.

Mullamullang Cave N37 is the longest and most complex cave on the Nullarbor Plain, Southern Australia. Unlike the other caves, it possesses extensive levels of phreatic solution tube passages which permit stronger inferences to be made on the development of the collapse passages constituting the bulk of Mullamullang Cave and other deep Nullarbor caves. These passages have been formed by collapse through overlying belts of solution tube networks along an elongated zone of cavitation in the limestone. Massive breakdown was probably initiated at depth within the zone, at least 50 feet below the present watertable level. Upward stoping of the collapse would have been facilitated by the higher network levels in the zone, such as the Ezam and Easter Extension. Channelling of groundwater flow under the Plain is suggested by the belt-like nature of the networks. An epiphreatic origin is proposed for the network levels though convincing morphological evidence is wanting. Eustatic changes in sea level have been of fundamental importance in the development of the multiple levels. Wetter periods in the past were probably important as little development is taking place under present-day dry conditions. Correlation of wetter periods with Pleistocene glacials would help explain the development of huge collapse passages, but such correlatien cannot be assumed on present evidence. Massive collapse and doline formation were followed by subaerial weathering and vadose activity which modified the cave - especially near the entrance. Correlation of levels in Mullamullang with those in other Nullarbor deep caves is attempted. However, Mullamullang Cave is unique probably due to the lithology of the Abrakurrie Limestone in which it is developed.


Four new Bathynella (Crustacea, Syncarida) of Romania; again on the ''Dilemma Bathunella natans Vejd''., 1971, Serban Eugne
The paper presents the diagnosis of 4 new Bathynella species found in Romania: B. paranatans nov. sp., B. boteai nov. sp., B. motrensis nov. sp. and B. plesai nov. sp.; a discussion on B. cf. scythica Botosneanu et Damian is also given. The morphological features which were used are the general and the fine structure of the genital pereiopode of the male (Pl. 58), the chaetotaxy of the maxillula, maxilla, thoracic appendages, uropods and furca. The presence of the distal (coxal) epipodite on the first pereiopod in E. paranatans nov. sp., distinguishes this species from the others (Pl. 14). The true taxonomical value of the VIIIth pereiopod of the male is pointed out, which; at least in the case of these species; shows, by its general structure, the relationships, the heterogeneous morphology of the anterior plate (PI. 5- 8, a), marking the speciation.
