A Pre- And Post-Improvement Study On Six Southeast Kansas Strip-Mine Lakes, William Thomas Waller

Electronic Theses & Dissertations

During the last sixty years extensive experimental research has been conducted in an attempt to establish methods of controlling the acid conditions resulting from coal mine operations.

It was the purpose of this research to determine the feasibility of reclaiming acid strip-mine lakes for use as potential fisheries management areas. To accomplish the objectives outlined above a two-phase program was initiated. The first phase involved the physical alteration of the drainage areas of the experimental lakes included in this study in an attempt to divert all visible signs of acid drainage to areas other than those incorporated into the drainage …

Panthera Atrox (Mammalia: Felidae) From Central Alaska, Frank C. Whitmore Jr., Helen L. Foster

United States Geological Survey: Staff Publications

A lower jaw of the large Pleistocene cat Panthera atrox (Leidy) was found on an alluvial flat near the mouth of Lost Chicken Creek, about 180 miles northeast of Fairbanks, Alaska. It was probably washed out of carbonaceous silt deposits which, in the adjacent area, have also yielded bones of Equus, Bison, Rangifer, Cervus, and Elephantidae. The Panthera jaw falls within the size range of the series from Rancho La Brea, California, and differs from Rancho La Brea specimens only in a few characteristics. P. atrox appears to have been significantly larger than extinct or …

Sur La Faculté D'Absorption De Substances Colorées Par La Cuticule De Caecosphaeroma Burgundum Dollfus, Crustacé Isopode Des Eaux Souterraines, François Graf, Claude Marvillet

International Journal of Speleology

The discovery, in certain subterranean waters, of “pigmented,” brown or black Caecosphaeroma burgundum, led to the systematic study of the action of pigmented substances on these crustaceans. The results of these experiments demonstrate that the colorations thus obtained or observed in nature are due to the agglutination of coloured substances on the surface of the carapace and, in certain cases, to an impregnation of the cuticle itself.

Documents Pour Servir À La Connaissance De La Laune De Mammifères Des Grottes Du Banat (Roumanie), Alexandrina Negrea, Lazare Botosaneanu, Stefan Negrea

International Journal of Speleology

The authors assembled from about 70 caves a rich collection of osteological material and specimens of living or fossil mammals. A list of the caves is given with an enumeration of the identified species for each cave. Under each species the caves which supplied the material are listed. This is followed by an inventory of the osteological material and by observations on the living animals (especially bats). Fifty-three mammal species (fossil and living) were accurately determined (14 carnivores, 6 artiodactyls, 1 lagomorph, 10 rodents, 3 insectivores, and 19 bats).

A Psychrophilic Yeast From Mammoth Cave, Kentucky, David Brashear, Ralph F. Wiseman, Thomas C. Barr Jr.

International Journal of Speleology

Samples collected in Mammoth Cave, Kentucky, revealed the presence of a psychrophilic yeast, tentatively identified as a strain of Candida albicans. The yeast is saprophytic on dead animal tissues and exhibits a pale yellow colour when growing in the cave. In vitro, the yeast grows poorly at 37°C. and well at 130 and 200, but loses its pigmentation. It is non-pathogenic in rabbits but appears to show low-grade parasitism in frogs.

Some physical data collected over a period of a year in seven locations of the Ogof Ffynnon Ddu cave system in South Wales are reported, including humidity, air and water temperature, pH of the water, as well as the organic oxygen demand of the water. It is shown that seasonal variations in the physical constant in this particular cave system are not well marked. Algae and bacteria were isolated from the soil samples and from calcareous deposits. A total of 30 algal species, of which 13 belong to the Cyanophyta, 22 to the Chlorophyta, and 7 to the …

Die Ökologische Stellung Der Höhlen-Und Spaltengewässer Innerhalb Der Subterranaquatilen Lebensbereiche, Siegfried Husmann

International Journal of Speleology

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 …

The results of an investigation into the bacterial and botanical flora of South Welsh caves are presented in tabular form. Bacterial counts and species isolated from the caves both from soil and water samples as well as from the air, also the macroscopic plants found in the photic zone are enumerated.

Mise En Evidence De Substances Fluorescentes Dans Les Organes Jaunes De Caccosphaeroma Burgundum Dollfus, Crustacé Isopode Des Eaux Souterraines, H. Descimon, C. Marvillet

International Journal of Speleology

Chromatographic analysis of the yellow organs of the fresh-water Isopod Crustacean Caecosphaeroma burgundum Dollfus revealed, through observation of the chromatograms in ultraviolet light, the occurrence of both absorbing and fluorescent substances. Among the latter, only isoxanthopterin has been identified. The yellow pigment, which probably has a pteridine nucleus, could not be identified as a known compound and will be the object of later investigations.

The Course Or Behavior Of Applied Zinc To Soil Containing Different Levels Of Freshly Applied Organic Matter, Artnel Samuel Henry

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Soil organic matter consists of a heterogenous mixture of plant, animal, and microbial material in various stages of decomposition. It possesses characteristics which at present are not very well known. Careful studies have been directed towards the behavior of organic matter as it affects plants directly and man indirectly. Consequently, much tire is devoted to its study from the point of metal inactivation and chelation, the earlier investigations failed to produce results worthy of the efforts expended, so a loss of interest in the continued pursuit of knowledge resulted, about two decades ago when it was learned that many polyvalent …

The Influence Of Organic Matter And Ph On Transformations Of Nitrites To Elemental Nitrogen, Mohammad A. Rashid

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Nitrogen occupies an important and prominent place in plant and animal nutrition. Large quantities are required by plants and must be available in the soil. Recently the use of nitrogenous fertilizers has increased manyfold. In view of the importance of this element in crop production, even greater use is anticipated in the coming years. In order to make full use of the applied nitrogen, continued investigations of soil-nitrogen relationship are imperative; however, this element presents many complex and challenging problems to investigators.

Simultaneous Flow Of Heat And Water In Plant Tissue, Gaylon Sanford Campbell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Although biological phenomena may be partially described in a general way without the use of mathematics and physics, the experimental results may be more meaningful if they are analyzed on the basis of physical and mathematical laws. The complexity of biological systems has made the application to them of mathematics and physics rather difficult, and only recently has much progress been made. Although it has yet been possible to describe only a few simple biological systems by actual equations, a great deal of qualitative information may be obtained by applying physics and mathematics. Russell (1960, p. 439) said

Movement Of Phosphorus In Soils As Influenced By Chelates And Soil Types, Abd-Elmonem Sayed-Ahmad Mostafa

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The problems of phosphate fertilization have attracted the attention of agronomists, nutritionists, and other biological scientists due to the importance of phosphorus in animal and plant nutrition. However, the fundamental behavior of phosphorus in soil systems is not well understood. Because of its far-reaching effects, a solution of a portion of this problem is of importance.

The Relationship Of Flooding And Saline Water Tables, Stanley Thomas Smith

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

IN Western Australia there are several ways in which salt manifests itself but the most serious and extensive of these is in the valley systems where shallow saline water tables occur.

This type of salt problem is called "valley waterlogging" and occurs in most of the flat valleys throughout the wheatbelt of W.A.

Developpement Larvaire Du Serpulien Cavernicole Marifugia Cavatica Absolon Et Hrabe (Polychaeta, Sedentaria), Janez Matjašič, Boris Sket

International Journal of Speleology

Among material coming from Hercegovina some living trochoporae of the cave Serpulid Marifugia cavatica have been found. In the laboratory of the Biology Institute of Ljubljana the further development passing stages of metatrochophore and nectochaeta have been observed. The constitution of the trochophore is typical. The nectochaeta possesses three metamera and each of these has only one pair of setae. The nectochaeta once it gets attached to the bottom the neck and beginning of tentacles are beginning to develop. The tube, three pairs of simple tentacles and the opercula are formed in further stages. For the period in which the …

A Preliminary Study On The Effects Of Organic Pollution Of Banners Corner Cave, Virginia, John R. Holsinger

International Journal of Speleology

Four pools were observed in Banners Corner Cave, Russell County, Virginia, over a 28 month period from November 1961 to February 1964. Three of these pools were visibly polluted with sewage which had seeped into the cave from septic tanks located on the hill above. All four of these pools, at one time or another during the study, contained large populations of planarians, Phagocata subterranea Hyman and isopods, Asellus recurvatus Steeves. Physicochemical and microbiological analyses of the pool waters indicated that oxygen tension is a low as 2.8 mg./l. in one pool and that coliforms and other forms of bacteria …

Ecology And Distribution Of Foraminifers Of A Traverse In The Northwestern Gulf Of Mexico, Faiz Nassir Thomas

Masters Theses

"Foraminiferal populations have been analyzed from five bottom samples along a traverse in the northwestern Gulf of Mexico, approximately 27⁰20' to 97⁰15' north latitude and 97⁰20' to 97⁰05' west longitude. Eighty-eight species and twenty-nine genera, belonging to eighteen families, were recorded. Species were identified and described.

Statistical studies indicate that probably five benthonic foraminiferal depth facies could be recognized in the area at the following approximate depths: 4 fathoms, 4-8 fathoms, 8-12 fathoms, 12-16 fathoms, and 16-20 fathoms. Determination of facies is based largely on the range of species. The frequency distribution of species of foraminifers was plotted against change …

Origin And Factors Affecting Distribution Of Solid Oil In Mid-Western Missouri, Rafid Abdul-Halim Jasim

Masters Theses

"A textural analysis was made of the heavy oil-bearing sandstones in the Middle Pennsylvanian (Desmoinesian) Warner and Bluejacket formations of mid-western Missouri in order to determine and compare their depositional environments.

Grains of the Bluejacket sandstones are smaller and more rounded than grains of the Warner sandstones. The Bluejacket sandstone is also better sorted than the Warner sandstone.

The Bluejacket sandstone is thin-bedded; the Warner is mostly massive-bedded. These differences in bedding between the two formations have affected distribution of oil in the area of study.

Both the Bluejacket and Warner sandstones are better sorted than the Warrensburg sandstones; the …
