Nebraska In Relation To The Problems Of Pleistocene Stratigraphy, Alvin Leonard Lugn

Department of Earth and Atmospheric Sciences: Faculty Publications

Nebraska is so peculiarly situated with respect to Pleistocene deposits of glacial, fluviatile, and eolian origin that it holds the key to the solution of many important problems of the stratigraphy of that period. A brief outline of the Pleistocene geology of Nebraska with several illustrations is followed by a statement of and brief discussion of several of these problems. The main problems touched upon are: age of the Loveland loess, Pleistocene classification, correlation with Europe, the need for a better understanding of what is meant by "glacial" and "interglacial," the problem of glacial and interglacial loess, the duration of …

Fermentation Of Sugar Acids By Bacteria, Gordon B. Robbins, Keith H. Lewis

Chemistry Department: Faculty Publications

Bacterial fermentation of the sugar acids has received little attention in comparison with the wide-spread use of the common aldoses and sugar alcohols. These acids, and especially their sodium salts, are well suited to bacteriological techniques because of their solubility and heat stability, yet their usefulness for investigating the relationship of chemical structure to biological utilization has only recently been recognized. Their application to systematic differentiation of bacteria has also been neglected.

Kendall, Bly and Haner (1923) concluded from a study of three monocarboxylic acids and three dicarboxylic acids that these compounds possessed little value for the differentiation of bacterial …

Effect Of Organic Matter Decomposition On The Solubility And Fixation Of Phosphorus In Alkaline Soils, H. F. Rhoades

Nebraska Agricultural Experiment Station: Historical Research Bulletins

It is the purpose of this bulletin to report a laboratory study on the effects of organic matter decomposition on the solubility and fixation of phosphorus in alkaline soils. The study included the following: (1) a comparison of the effects of a decomposing organic material with those of a physiologically acid nitrogen fertilizer, and (2) a comparison of the effects of different organic materials of varying phosphorus contents.

Effect Of Soil Type, Slope, And Surface Conditions On Intake Of Water, F. L. Duley, L. L. Kelly

Nebraska Agricultural Experiment Station: Historical Research Bulletins

In connection with investigations of runoff and erosion in the Great Plains an attempt has been made by means of artificial applications of water to determine certain principles concerning the effect of different soils and soil conditions on runoff and soil erosion. Such information is needed in planning all field operations dealing with soil erosion and moisture control. It is also needed in connection with watershed studies that are being established in the Central Great Plains, dealing with runoff and flood flows from larger areas. The method employed makes it possible to obtain comparable data on a wide range of …

The Comparative Ability Of The Bob-White And The Ring-Necked Pheasant To Withstand Cold And Hunger, Paul L. Errington

Other Publications in Wildlife Management

The native Bob-white (Colinus virginianus) and the introduced Ring-necked Pheasant (Phasianus colchicus torquatus) may both, on occasion, suffer severe winter mortality over much of their common range in north-central United States. Their habitats often overlap, although the Pheasant has a greater cruising radius and an ability to live in a more open type of country than the Bob-white. In given localities they also live upon much the same kinds of winter foods.

The scope of this paper is not intended to cover the ecological adjustments of Pheasants or of Bob-whites to their winter environment so much …

A New Giant Camel Gigantocamelus Fricki, Gen. Et Sp. Nov., Erwin Hinckley Barbour, C. Bertrand Schultz

A lower Pleistocene deposit containing fossil vertebrates near Broadwater, Morrill county, Nebraska, has been reported upon by the writers, beginning three years ago. Five fossil quarries have been opened since the site was discovered in 1936.

The White River Oligocene Rodent Diplolophus, Erwin Hinckley Barbour, Thompson M. Stout

Bulletin of the University of Nebraska State Museum

The rich and varied nature of the mammalian faunas of the White River Oligocene has been recognized for many years, but the exact geologic succession is only now becoming known. In these faunal assemblages the rodents and lagomorphs appear to have been important elements, perhaps numerically as abundant in the Oligocene as are these same groups at present.

An account of a fossilized log at Ginkgo Tree State Park written by the man who discovered the fossil trees and established there were Ginkgo trees in North America in the distant past.

The booklet is written from the perspective of one of the fossilized trees, tracing the geologic forces that led to it becoming a fossil.

An Outline Of The Principal Natural Resources Of Nebraska And Their Conservation, George E. Condra

George E. Condra Publications

Nebraska is well endowed with important natural resources, such as stone, clay, sand, soil, water, prairie, forests and wildlife. However, soil and water are our basic heritage because they, more than other resources, support native life, agriculture, industry, and social development.

Classification Of The Tertiary System In Nebraska, Alvin Leonard Lugn

Department of Earth and Atmospheric Sciences: Faculty Publications

This paper represents the results of almost continuous research by the Nebraska State Geological Survey on Tertiary stratigraphy in Nebraska during a perIod of more than 10 years, with special attention to the present acceptable stratigraphic nomenclature. Cogent reasons are presented for the retention of such well-known names as White River, Arikaree, and Ogallala, all now redefined and elevated to group ranking. “Loup Fork” and “Loup River,” "Nebraska beds", and “Republican River" are considered obsolete. The application of fossil seed zones to problems of correlation is noted. The table of Tertiary Formations of Nebraska summarizes the Tertiary stratigraphy in Nebraska.

When you slip into the large and comfortably cushioned seat of a Farmall-H or a Farmall·M nd rest your hands on the large, automobile type steering wheel. right away you feel at home. As your left foot just naturally finds the clutch pedal and you put the tractor into gear you begin to get the feeling that here is a tractor that is as easy 10 drive as the family car. And as you give it the gas (gasoline. distillate or kerosene). and let in the clutch, you get the thrill which comes with the realization that here, under finger.tip …
