Native Midwestern Pastures: Their Origin, Composition, And Degeneration, J. E. Weaver, W. W. Hansen Feb 1941

Native Midwestern Pastures: Their Origin, Composition, And Degeneration, J. E. Weaver, W. W. Hansen

Department of Agronomy and Horticulture: Faculty Publications

According to Doctor J. E. Weaver and Mr. W. W. Hansen the purpose of this bulletin is to present certain facts involved in range and pasture management by outlining in some detail the fundamental phenomenon of vegetational change upon which all rational pasture studies must be based. They maintain that the native prairie vegetation is an organic entity in close adjustment with soil and climate, which has developed gradually to its present condition of dynamic stabilization. When the prairie is grazed and trampled, various changes occur, the nature and extent of which vary somewhat directly with the degree of disturbance, …


Bulletin No. 295 - Comparison Of Two Methods Of Determining Wool Density, Milton A. Madsen, Ralph W. Phillips, John V. Christensen, Roy L. Henrie Jan 1941

Bulletin No. 295 - Comparison Of Two Methods Of Determining Wool Density, Milton A. Madsen, Ralph W. Phillips, John V. Christensen, Roy L. Henrie

UAES Bulletins

Density of the fleece is one of the primary factors determining the wool-producing capacity of the sheep. Sheepmen have attempted to evaluate density by handling the fleece. This method is not sufficiently refined for use in experimental work, and may be subject to errors and misinterpretations. For example, if two fleeces are alike in density and diameter of fibers, yet differ in length, the longer fleece will feel less dense. If, on this basis, the sheep with the fleece that appeared most dense were selected for breeding, selection would be away from the longer fleece. Any method that can be …

Wildlife Of The Atlantic Coast Salt Marshes, W. L. Mcatee Jan 1941

Wildlife Of The Atlantic Coast Salt Marshes, W. L. Mcatee

United States Fish and Wildlife Service: Publications

Salt marshes of the Atlantic coast have been formed under the opposed tendencies of sinking of the land and of its upbuilding by silt and sand. The plants that form the marshes occupy zones largely determined by the degree of inundation by tides. Eelgrass entirely submerged, smooth cordgrass regularly washed by the tide, and marsh hay covered only by exceptionally high water are characteristic plants. Each zone is the home or feeding area of certain kinds of wildlife. The appearance, distribution, and habits of the more common species are described, and general wildlife conservation is urged. This circular, which is …

During the summer of 1928, a University of Nebraska State Museum field party, composed of Dr. A. L. Lugn and the writer, made a collection of upper Miocene and lower Pliocene mammals in Brown and Cherry counties, Nebraska. This collection was sponsored and made possible by the generosity of the late Hon. Charles H. Morrill.


Preliminary Report On The Legumes Of The Arkansas Uplands, Orrin J. Henbest Jan 1941

Preliminary Report On The Legumes Of The Arkansas Uplands, Orrin J. Henbest

Journal of the Arkansas Academy of Science

A brief discussion is presented on the ecologic, taxonomic, and economic features of the leguminous plants of the uplands occupying the northwestern half of Arkansas. The list of 37 genera and 115 species is compiled from the author's collection and from the specimens in the herbarium of the University of Arkansas collected in this part of the state. The geographic position of this area and its variety of ecological habitats indicate that it may yield nearly 175 species of legumes.

Common Birds Of Southeastern United States In Relation To Agriculture, F. E. L. Beal, W. L. Mcatee, E. R. Kalmbach Jan 1941

Common Birds Of Southeastern United States In Relation To Agriculture, F. E. L. Beal, W. L. Mcatee, E. R. Kalmbach

United States Fish and Wildlife Service: Publications

From a purely practical point of view the most important of the relations of native birds to man are the economic. The esthetic value of birds is great, greater indeed than that of any other group of animals; and that this is a real and especially a treasured value is not to be denied. But it is in their relation to insect and other enemies of crops that birds are most directly associated with the welfare of mankind, and their value in this particular should be made as widely known as possible. This bulletin is one of a series designed …

Phylogenetic Studies On The Blood-Inhabiting Trematodes, Harold Frederick Dieckmann Jan 1941

Phylogenetic Studies On The Blood-Inhabiting Trematodes, Harold Frederick Dieckmann

University of the Pacific Theses and Dissertations

Trematodes belonging to the blood-inhabiting group have long attracted the attention of parasitologists and medical men, especially those trematodos belonging to the family Schistosomidae because throw widely distributed species, Schistosoma Japonicum, S. haematobium, and S. mansoni, are parasitic in man, and in endemic regions are the cause of important human diseases. These schistosomes, with a few exception, have undergone more detailed research than any other trematodes.

Since the discovery of the first digenetic trematode exhibiting sexual dimorphism by Rudolphi (1819), which was named Distoma canaliculatum, and the descriptions of the other blood flukes up until the present time, a vast …


Trees And Shrubs Of Kings Canyon National Park, Kenneth M. Stocking Jan 1941

Trees And Shrubs Of Kings Canyon National Park, Kenneth M. Stocking

University of the Pacific Theses and Dissertations

In 1935 I first visited the Kings Canyon area. Since then I have spent many hours wandering through the woods and over the mountains in the area around the old General Grant National Park and the country which is now included in the Kings Canyon National Park. To my knowledge, no complete flora has been made for this vicinity. I consider the following pages to be the beginning of a fascinating work. It is the beginning because this paper includes only plants with woody stems.

Bulletin No. 294 - Research Aids Utah Agriculture: Biennial Report Utah Agriculture Experiment Station 1938 - 1940, R. H. Walker

UAES Bulletins

The foundation of progress in agriculture as in any other industry is research. Research has resulted in knowledge now daily applied in soil treatment, in irrigation practices, in dealing with insect pests, in breeding new varieties of plants, in animal improvement, in better farm practices, and in better land-use planning. Research undertaken by the Utah Agricultural Experiment Station has been outlined to solve specific problems facing Utah agriculture, among them the problems of irrigation, dry farming, range management and animal production. The prosperity of the state is dependent upon the success of these agricultural enterprises. Agricultural research should not, therefore, …

Cooling, Storage, And Transporation Of Milk And Cream, P. A. Downs, F. D. Yung Sep 1940

Cooling, Storage, And Transporation Of Milk And Cream, P. A. Downs, F. D. Yung

Nebraska Agricultural Experiment Station: Historical Circulars

The care given milk and milk products should be such that they will be relished by young and old alike. Greater use of milk can be encouraged by serving fresh milk cold. Cooling of milk also insures a fine product several hours after production. This is important not only for milk that is to be used, but for milk or cream that is to be sold.

The Utilization Of Food Elements By Growing Chicks. Ix. The Nitrogen Of Urea, C. W. Ackerson, W. E. Ham, F. E. Mussehl

Nebraska Agricultural Experiment Station: Historical Research Bulletins

1. The effect of replacing one-third of the concentrate of a ration for growing chicks with a mixture of starch and urea that contained an amount of nitrogen equal to that contained in the concentrate withdrawn from the ration was studied with two lots of chicks. 2. All chicks of both lots consumed equal amounts of nitrogen during the experiment. 3. Conclusions were based on increases in body weight and content of nitrogen, calcium and phosphorus at slaughter.

A Study Of The Geographical And Ecological Distribution Of The Buffy Plains Pocket Mouse (Perognathus Flavescens Flavescens), With Description Of A New Subspecies From Nebraska, Myron H. Swenk Jun 1940

A Study Of The Geographical And Ecological Distribution Of The Buffy Plains Pocket Mouse (Perognathus Flavescens Flavescens), With Description Of A New Subspecies From Nebraska, Myron H. Swenk

University of Nebraska State Museum: Mammalogy Papers

The Buffy Plains Pocket-mouse (Perognathus flavescens flavescens) is a typical mammal of the Sandhill Region of Nebraska. Its home, like that of other species of pocket-mice, is a series of burrows in the ground, consisting of several entrance holes leading to the main 'burrow, in which is located the nest and the food storage chambers. In the Nebraska sandhills its burrows and nests are commonly placed beneath clumps of Spanish Bayonet or Prickly Pear Cactus, and the entrance holes usually are so distributed as to open from under the plant in all directions.

The writer had hoped to …


The Influence Of Whole Wheat, Bran And Shorts On Body Weight And Feather Growth In Chicks, F. E. Mussehl, C. W. Ackerson, M. J. Blish May 1940

The Influence Of Whole Wheat, Bran And Shorts On Body Weight And Feather Growth In Chicks, F. E. Mussehl, C. W. Ackerson, M. J. Blish

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The proteins of the entire wheat kernel and of the bran and shorts are apparently utilized with equal efficiency by growing chicks when used with a base of corn, barley, oats, meat scraps, fish meal, and soybean meal. The relatively higher protein levels of bran and shorts, as compared to ground wheat, should be considered by the poultry producer in deciding which product or products can be used with greatest economy. A good concentration of a feather-growth factor is found in wheat bran. Other common feedstuffs carry the same essential, and the amount of bran which should be used in …

Weight Loss With Carbohydrate-Free Diet In Male Albino Rats, Carroll R. Olson May 1940

Weight Loss With Carbohydrate-Free Diet In Male Albino Rats, Carroll R. Olson

Bachelors’ Theses

There are a good many clinical facts which suggest that people vary in their susceptibility to dietary deficiency disease. Hence, not all of the crew of a scurvy-ridden ship, come down, nor does everyone in a famine zone develop malnutritional edema.
