Über Die Moose, Die Unter Dem Einfluβ Der Elektrischen Beleuchtung In Das Innere Der Höhlen In Ungarn Und In Der Tschechoslowakei Eindringen, A. Boros

International Journal of Speleology

The introduction of electrical illumination into different caves makes the intrusion of some mosses and ferns into such depths of the caves possible which at previous occasions (i. e. before the installation of electrical light) were found sterile of these plants. Investigations of two caves in Czechoslovakia and 4 caves in Hungary revealed the presence of mosses thriving deep inside of these caves making use of the artificial illumination.

Naissance De La Biospéologie, Constantin Motas

International Journal of Speleology

Modern biospeleology dates from May 15, 1907, with the publication of Racovitza’s “Essai sur les problèmes biospéologiques.” 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 …

Remarques Sur La Signification Des Expériences En Géodynamique Karstique, Ph. Renault

International Journal of Speleology

Distinction is made between the experiment which “demonstrates” having an argumentative value - and the experiment which “questions” nature by isolating one factor and by determining the mode of its action. The concept of experiment in geology and in geodynamics and the distinctions between geodynamics and geophysics are discussed. Karstic geodynamics considers the action of fluids - mainly liquids - on a soluble rock. It is a science bordering the different branches of geochemistry, hydrology, the mechanics of rocks, and geophysics. Researches in karstic geodynamics are based upon measurements obtained through field surveys, or upon the utilization of a subterranean …

Écologie De Fonticola Notadena De Beauchamp (Turbellarié, Triclade) Dans La Grotte De La Balme (Isère, France); Survie En Période De Sécheresse, René Ginet, Rodolphe Puglisi

International Journal of Speleology

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.

Detection Of Caves By Gravimetry, Raymundo J. Chico

International Journal of Speleology

For gravimetric investigations, a naturally occurring limestone cave may be compared with a buried empty sphere or cylinder, depending on its shape. The practical limit of detection for a subsurface void, utilizing available equipment (Worden gravity meter) and standard field procedure, is 0.1 milligal. Most corrections normally required by the gravimetric method may be neglected in cave detection, but the altitude control for the field traverse must have an accuracy of ± 0.1 foot. The detectability of a limestone cave, based on field work done at Luray Caverns, Virginia, and at other localities, is related to its shape, Radius (R), …

Die Bedeutung Der Pleistozänen Vogelfaunen Der Höhlen Im Ungarischen Mittelgebirge, Tibor Farkas

International Journal of Speleology

In the present study, the fossil bird fauna of the caves of the Hungarian Middle Mountains is examined for evidence in support of the hypothesis that the Carpathian Basin may have served as a faunal refugee during the last Quaternary glacial period. As an introduction, the reasons for the refugee hypothesis, including paleobotanical and glacial theoretical aspects, are discussed. Since the first bird fossils of the cave fauna considered in this paper belong to the Würm I-II, the faunistic conditions of the Riss glacial period are not discussed in detail, The known faunas up to the Würm II are interstadial, …

Processes Of Limestone Cave Development, Alan D. Howard

International Journal of Speleology

Three processes successively predominate in enlarging original fractures within limestone into cavern passages: (1) early dissolving by acid produced by oxidizing reactions within the groundwater as it flows through the limestone; (2) dissolving caused by the initial undersaturation with respect to calcite of the groundwater when it enters the limestone; and (3) increased dissolving which occurs at the transition from laminar to turbulent groundwater flow. Only those original fractures in limestone which are widest and which have a high hydraulic gradient acting across them will be enlarged into cavern passages. Until all available surface drainage has been diverted underground, cavern …

Essai Sur Une Étude Au Microscope Électronique De La Microflore Des Sédiments Argileux De Cavernes (A Preliminary Study Using An Electron Microscope, On The Microflora Of Cave Clay Sediments), V. Caumartin

International Journal of Speleology

Researches on the microflora of cave clay sediments were carried out. The study of these micro-organisms necessitates the use of an enlargement of the order of 5,000. For this purpose the organisms were separated from the clay sediments by the foam flotation technique, followed by cultivation. Morphologically they can be divided into 5 types but together they form a group sufficiently homogeneous to justify their provisional grouping as the “Microfusiformetum.” Experiments with enriched cultures from several sediments have shown that certain of the micro-organisms were indigenous, others were accidental inhabitants.

Observations Sur L'Évolution Des Grottes, Albert Cavaillé

International Journal of Speleology

In this note, which results from a paper published in France, the author defines the “karst system” formed by several successive levels, at the heart of a limestone mass: joints of surface feeding, vertical chimneys, galleries which are alternatively dry and full of water according to the season, a network of continually drowned clefts. He then studies modifications in this system resulting from internal causes, corrosion, filling and sedimentation, concretion. Then he shows how this evolution of the karst system may be modified by general conditions: geology, tectonics, geography with the losses, resurgences and the role of surface formations. The …

Set Stocking Has A Place In Soil Conservation Farming, J E. Watson

Journal of the Department of Agriculture, Western Australia, Series 4

Set stocking of sheep at increased stocking rates is rapidly becoming popular with farmers in the agricultural areas of Western Australia.

But will set stocking increase soil erosion hazards? It should do just the reverse, according to Soil Conservation Adviser J. E. Watson, B.Sc, who claims that set stocking has a place in soil conservation farming.

Planning New Farm Dams : Excavated Earth Tanks, J E. Watson, J. C. Grasby

Journal of the Department of Agriculture, Western Australia, Series 4

A GOOD farm dam is a valuable asset, and well worth its cost, but there are many aspects to consider when a new dam is required. Careful planning with adequate testing and checking will help to get the best value for money and reduce the chance of costly failures.

This article discusses these aspects in relation to the excavated earth tank type of dam.

Über Die Algenwelt Der Höhlen In Ungarn, P. Palik

International Journal of Speleology

An account of the researches carried out on the algae living in the caves of Hungary is given. The results of the investigations concerning the algal flora of the Baradla, Peace, Abaliget, Pàlvòlgy, Kòlyuk caves are enumerated. Theories about the possible energy source utilized by these algae living in the complete darkness of caves such as radiation, symbiosis, chemosynthesis or auxothrophy are discussed. The question of the settling of algae into the caves is debated.

Corrosion Par Mélange Des Eaux, Alfred Bogli

International Journal of Speleology

Karst caves are prior to all due to corrosion. According to the well-known formula a CO₂ supply is always needed. This type of dissolution explains only the corrosion in free circulation and, under reserve, the one in pressure conducts in the vadose zone. All corrosion in the phreatic domain is excluded, except for some rare cases in the upper levels. The corrosion by mixing of waters of different content in bicarbonates is effective in the entire karst, from the lowermost to the uppermost parts. Also the corrosion due to the lowering of temperature and by mixing of waters at …

Land Preparation For Border Irrigation, B Swan

Journal of the Department of Agriculture, Western Australia, Series 4

LARGE amounts of water may be lost through excess run-off and deep percolation.

Proper preparation of irrigation land can help to minimise these losses.

This preparation is done by grading or levelling so that the original ground surface is shaped to allow for a more uniform distribution of water.

Progress In The Control Of Cotton Fireweed, Geoffrey A. Pearce

Journal of the Department of Agriculture, Western Australia, Series 4

Cotton Fireweed (Erechtites quadridentata) is native to Western Australia and was first collected by Drummond before 1850. In its natural habitat it is quite insignificant and passes unnoticed.

Cotton fireweed, a native perennial plant, has become a serious weed in the south coastal districts and is now one of the most widespread weeds in the State.

Swing Fence Flood Crossing For Creeks In The Kimberleys, A L. Payne

Journal of the Department of Agriculture, Western Australia, Series 4

FENCING is the basis of the regeneration programme on the eroded Ord River catchment area, and the fences constructed must cross numerous creeks.

But heavy downpours of short duration characterise the wet season experienced in this area.

Because the rain falls on to bare, compacted ground, run-off is intense and gullies and creeks rise rapidly, causing serious damage to conventional fences and flood gates across watercourses.

Profitable Returns From Saltland, C V. Malcolm

Journal of the Department of Agriculture, Western Australia, Series 4

The recent saltland survey disclosed that about 305,000 acres of land previously cleared and sown had become salt affected.

This represents a serious loss in production but is offset by the fact that much of the land is capable of producing high yields of good quality fodder.
