Naissance De La Biospéologie, Constantin Motas Jan 1964

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 Les Japygidae (Insecta, Diplura) Signalés Dans Le Domaine Souterrain, Jean Pagés Jan 1964

Remarques Sur Les Japygidae (Insecta, Diplura) Signalés Dans Le Domaine Souterrain, Jean Pagés

International Journal of Speleology

About 50 japygids, belonging to 29 distinct forms of which 23 are recognizable, have been collected since 1874 in caves all over the world. A list is given, by continent and by countries. Ten species found both in the soil and in caves are called troglophiles to emphasize the sorting which seems to occur among endogenous species. Of the remaining 13 species, all considered troglobites, only 3 show morphological peculiarities which can be ascribed to adaptation to cavernicolous life: (1) Metajapyx moroderi ssp. patrizianus Pagés from Sardinia shows a slightly longer 10th urite and cerci than the f. typ.; (2) …


Remarques Sur La Signification Des Expériences En Géodynamique Karstique, Ph. Renault Jan 1964

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 …


Die Bedeutung Der Pleistozänen Vogelfaunen Der Höhlen Im Ungarischen Mittelgebirge, Tibor Farkas Jan 1964

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, …

Origin Of Some Recent Tractional Sedimentary Structures In The Rio Puerco Near Bernardo, Socorro County, New Mexico, Lawrence H. Wagner May 1963

Origin Of Some Recent Tractional Sedimentary Structures In The Rio Puerco Near Bernardo, Socorro County, New Mexico, Lawrence H. Wagner

Earth and Planetary Sciences ETDs

The Rio Puerco, in the area of study, occupies a valley eroded in the Santa Fe formation. The silty alluvium is incised by the present channel of the Rio Puerco to a depth of 10 to 25 feet. The depth of the alluvial fill in the area is not known. The channel is 50 to 300 feet wide with braod meanders interspersed with straight reaches. The Rio Puerco is ephemeral in the lower reaches with flow produced by local rains on the watershed.


Petrography Of The Olalla Stock, Okanagan Mountains, British Columbia, James Anton Sturdevant May 1963

Petrography Of The Olalla Stock, Okanagan Mountains, British Columbia, James Anton Sturdevant

Earth and Planetary Sciences ETDs

The Olalla stock is located in the Okanagan Mountains of south-central British Columbia, about 20 miles north of the international boundary. It occupies approximately 6 square miles and consists of late Mesozoic mafic and ultramafic rocks and subordinate alkalic rocks, which have intruded previously folded and metamorphosed sediments of the Triassic (?) Shoemaker Foundation.

The rocks of the stock may be broadly grouped into two major categories: (1) those formed from the differentiation of a crystallizing magma that probably entered during the Nevadan orogeny, and (2) those formed by metasomatic replacement of pyroxenite. The rocks of the first category are, …


The Geology Of The South Mountain Area, Bernalillo, Sandoval, And Santa Fe Counties, New Mexico, Tommy B. Thompson May 1963

The Geology Of The South Mountain Area, Bernalillo, Sandoval, And Santa Fe Counties, New Mexico, Tommy B. Thompson

Earth and Planetary Sciences ETDs

South Mountain is approximately 30 miles northeast of Albuquerque in the southern end of the San Pedro-Ortiz porphyry belt. It is a Tertiary monzonite laccolith that intrudes the Permian Abo and Yeso Formations and, in places, the Permian Glori eta Sandstone. The base of the lac­eolith lies on the Abo except in the southeastern part where it overlies the Mes eta Blanca Member of the Yeso. The incompetence of the Yeso appears to nave allowed the monzonitic magma to spread laterally throughout the stratigraphic interval up to the Glorieta Sandstone which was more resistant and broken only locally by the …

Lithostratigraphy And Correlation Of The Mississippian System In Nebraska, Marvin P. Carlson May 1963

Lithostratigraphy And Correlation Of The Mississippian System In Nebraska, Marvin P. Carlson

Conservation and Survey Division: Faculty and Staff Publications

The purpose of this study is to describe and correlate rocks of Mississippian age within the state of Nebraska. Shales, generally classified as "Chattanooga" and commonly referred to as Devonian or Mississippian in the northern Mid-Continent, have been included in this study, although these shales are more generally believed to be Devonian and not Mississippian by most stratigraphers and paleontologists at the present time. Since rocks of Mississippian age are present only in the subsurface of Nebraska, the basic information for this report is derived from the microscopic study of cuttings and cores from test wells drilled within the state.


Differentiation Between The Ph Effect And The Bicarbonate Ion Effect In Causing Lime-Induced Chlorosis, Hyrum Del Var Petersen May 1963

Differentiation Between The Ph Effect And The Bicarbonate Ion Effect In Causing Lime-Induced Chlorosis, Hyrum Del Var Petersen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Lime-induced chlorosis has been recognized for many years as a problem where plants are grown on calcareous soils. There are many factors associated with and influencing this form of iron chlorosis and because of this it has been very difficult to determine the relationship between the factors and chlorosis.


Salt Effect On Water Requirements Of Plants, Abdel-Wahhab M. H. Sallam May 1963

Salt Effect On Water Requirements Of Plants, Abdel-Wahhab M. H. Sallam

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Water requirement was defined by Briggs and Shantz in 1911 as the ratio of the weight of water absorbed by a plant during its growth to the weight of dry matter produced. Ballard (1933) and Williams (1935) defined water requirement as the ratio of the amount of water transpired to the amount of dry matter produced. Ballard (1933) and Williams (1935) defined water requirement as the ratio of the amount of water transpired to the amount of dry matter formed during the whole or any part of the life cycle of the plant. Miller (1938) and Kramer (1959) postulated that …
