Bulletin No. 284 - Lygus Bugs In Relation To Alfalfa Seed Production, C. J. Sorenson

UAES Bulletins

This investigation, which continued during the two succeeding years, had four primary purposes: (1) to determine the distribution of these plant bugs and the intensity of their infestation in the alfalfa-seed districts of the state; (2) to ascertain whether these bugs constitute an important factor, either causing or contributing to, the excessive flower-drop annually occurring in alfalfa-seed fields, or if they are otherwise responsible for decreased yields of alfalfa seed; (3) to study the general biology of these insects with particular reference to their life histories in alfalfa as the host plant; and (4) to investigate possible practical methods for …

Bulletin No. 286 - Some Trends In Utah's Agriculture, Walter U. Fuhriman

UAES Bulletins

During the last two decades agriculture has been subjected to many strains and stresses- social, economic, physical, and biological. Infestations of noxious weeds and insect pests have in some instances necessitated changes in crops grown and in farming practices. Changes in precipitation have induced alternate expansion and contraction of cultivated acreage in certain areas. Improved machinery has reduced the demand for farm labor, caused shifts in crops grown and in farm population. Changes in dietary habits have increased the demand for some farm commodities and decreased the demand for others, while wide fluctuations in farm prices have wrought rapid changes …

Anatomy And Histology Of The Digestive Tract Of A Deep-Sea Fish Coelorhynchus Carminatus, Elly M. Jacobsen

University Studies (University of Nebraska) (1888–1984)

This paper deals with the anatomy and histology of the digestive tube of one of the grenadiers or rat-tails, Coelorhynchus carminatus (Goode), as classified by Jordan & Evermann (1896).1 Many studies on the structure of the digestive tracts of fishes have been made in the past, and pioneer work in the teleost group was done by Valatour in 1861, Pillet in 1894 on the Pleuronectidae, and Gulland in 1898 on the salmon. More recent studies have been made by Greene (1912) on the king salmon, Blake 2 (1930) on the sea bass, and Rogick (1931) on the minnow.

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

Bulletin of the University of Nebraska State Museum (1924–2023)

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 (1924–2023)

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.

Increase Of Sporobolus Cryptandrus In Pastures Of Eastern Nebraska, J. E. Weaver, Walter W. Hansen

Papers of John E. Weaver (1884–1956)

The severe drought of 1934 to 1938 has resulted in great losses in the plant
populations of native pastures. In Nebraska, little bluestem, Andropogon scoparius, and Kentucky bluegrass, Poa pratensis, have almost disappeared, while big bluestem, Andropogon furcatus, and numerous other important pasture grasses have suffered heavy losses. In addition to shiftings within the plant populations to compensate these losses, such as an enormous increase in side-oats grama, Bouteloua curtipendula, notable and widely spread local extensions have occurred. Over thousands of pastures western wheat grass, Agropyron smithii, has spread widely, and in similar numbers sand …

Birdbanding, Frederick C. Lincoln

United States Fish and Wildlife Service: Publications

Birdbanding, by means of numbered bands, provides a method of studying living birds of all kinds. Scientific banding dates back to 1899, when a Danish schoolmaster, H. Chr. C. Mortensen, commenced systematically to band storks, teals, starlings, and two or three species of birds of prey. His success at once attracted the attention of European ornithologists, and it was not long before the birdbanding work came into prominence. At the present time banding is being actively conducted in North America as well as in England, Finland, Norway, Sweden, Denmark, Russia, Iceland, Germany, Holland, Belgium, France, Switzerland, Hungary, Bulgaria, India, Morocco, …

A resume of the First Half-Century of Research 1888 - 1938 at the Utah Agricultural Experiment Station including the Biennial Report 1936 - 1938.

The Utah Agricultural Experiment Station in reaching the fiftieth year of its history can look back upon a brilliant record of achievement covering the practical as well as the more fundamental problems of agriculture in this arid state. The difficulties encountered in conquering deserts down through human history have demonstrated the mastery of man's spirit over his physical environment. Man's destiny to multiply, subdue, and replenish the earth cannot be accomplished by enjoying the fruits of …

The Aboriginal Utilization Of The Small Cacti In The American Southwest, Theodore Norris

Biology ETDs

The aim of this paper shall be, not simply to catalog the aboriginal uses of cacti in the Southwest, but to attempt to show their value to the aborigines as food, in general, and medical uses, ceremonial import, and their significance in myth and legend, in short, the place they occupied in southwestern life.

The Spinal Nerves And Spinal Cord Of The Frog, Laverne A. Penn

Bachelors’ Theses

The common grass frog, Rana pipiens as wall as the bull frog, Rana catesbiana have served during many decades as material from which both the student of zoology and the investigator in biological problems have gathered valuable information about the anatomy and physiology of the common systems. Among these systems the central, peripheral, and sympathetic nervous system plays a coordinating role, because of the ramifying nature of its organization. It is the purpose of this thesis to investigate the gross and histological structure of these branches known as spinal nerves. When one inspects the literature on the nervous system of …

Bulletin No. 280 - Sinusitis Of Turkeys And Its Treatment, D. E. Madsen

UAES Bulletins

Sinusitis has long been recognized as one of the barriers to profitable production of chicken products; and with the growth of commercial turkey production in the west its existence in this bird has become increasingly significant. In Utah areas considerable loss is encountered yearly from this disease in turkeys. This loss has prompted some investigations as to what measures may be adopted for its control.

Studies On The Vitamin A Content Of Cheese, I. L. Hathaway, H. P. Davis

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The vitamin-A contents of twenty-two kinds of cheeses were studied by feeding these cheeses to rats whose body stores of vitamin A had been exhausted by being fed a vitamin-A-deficient diet. Twelve experiments were made in which approximately 1100 rats were used. There was considerable variation in the vitamin-A content of the samples studied. The samples of cottage, Neufchatel, and Limburger cheeses had the lowest vitamin-A potency.

The Use Of Kerosene Sprays For The Control Of The Dandelion, Robert William Hanks

Biology ETDs

One of the most persistant weeds found in New Mexico lawns is the common dandelion (Taraxacum officinale Weber). In Albuquerque, where this study was made, most lawns are of Kentucky bluegrass (Poa pratensis L.), a poor competitor against the inroads of the dandelion. However, some lawns are of Bermuda grass (Cynodon dactylon pers.), which, with its thick and vigorous turf, is a better competitor with the dandelion. The writer has observed, as Dittmer also found, that the turf of Bermuda grass on the campus of the University of New Mexico will crowd out or prevent the entrance of dandelions, while …

An Investigation Of The Stomach Contents Of Micropterus Dolomieu, Richard Evan Horrall

Some Coccogoneales Common To The Vicinity Of Milwaukee, Joseph John Valenti

Bachelors’ Theses

The Cyanophyceae, a group of plants which are commonly known as the Blue-Green Algae, have a characteristic blue-green color due to a green pigment-chlorophyl, with which there is associated a blue pigment, phycocyanin. The Cyanophyceae are found everywhere on fresh salt water, on damp soil, rocks, bark, etc. These are among the simplest and lowest of all green plants. The plant consists of a single cell, but in most species these cells tend to adhere in colonies. These algae are able to grow at a higher temperature than can any other algae.

The Fresh-Water Sponges Of Wisconsin, James Russell Neidhoefer

Bachelors’ Theses

The fresh-water sponges were observed but not recognized as animals at a very early period. The early investigators thought they were plants; later workers, colonial protozoa. In 1696, Leonard Plukenet first made public mention of them; and later, in i745, Linnaeus described them as Spongia and made mention of their, "globuli". After Linnaeus the term Spongia changed many times until, in 1816, Lamarck introduced the generic name Spongilla.
