Ecological Study Of The Weed Population Of Eastern Nebraska, Elva L. Norris

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

EXACT knowledge of the relations existing between weeds and cultivated crops is very limited. This is true also of the amount of viable weed seed present in arable soil. Impressions and observations have been recorded, but very few quantitative investigations have been made. The numerous circulars and bulletins about weeds, issued by many experiment stations, deal mostly with descriptions of species and methods of weed control. The present research was undertaken primarily to determine the relationship which exists between weeds and cultivated crops, but also to obtain an estimation of the number of viable weed seeds present in the soil. …

Origin Of The Menard "Crater", Emmett Blakemore

Field and Laboratory

On August 30, 1938, the foreman of the Wilkerson Ranch twelve miles southwest of Menard, Texas, reported that a meteorite fell on the ranch and created a large crater. The story, widely publicized by newspapers, caused the writer, accompanied by Professor J. D. Boon of Southern Methodist University, to investigate this phenomenon.

The Hesperiidae Of Dallas County, Texas, Avery Freeman

Field and Laboratory

A Century Of Scientific Exploration In Texas, Part Ib: 1820-1880, S. W. Geiser

Field and Laboratory

In the fourth volume of this journal, I published a list, with short biographical notices, of naturalists and men of science who worked in Texas from 1820 to 1880. In that paper I promised a second contribution, to deal with naturalist-collectors and students in Texas during the years 1881-1920, thus rounding out a century of scientific study and exploration in the State.

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, …

The Efficiency Of Churn Washing Method And The Keeping Quality Of Butter As Indicated By Yeast And Mold Counts, T. Allen Evans

Electronic Theses and Dissertations

Of all the equipment used in the manufacture of butter, no single piece has as close contact with the finished product as does the churn while at the same time no piece of equipment is more difficult to keep properly cleaned. The workers in the dairy industry have expended much time and effort attempting to build a churn which could be kept in a more satisfactory state, especially from a bacteriological point of view. As yet no satisfactory material for churn construction has been found to replace wood which at best is difficult to keep free of micro-organisms. Since it …

An Annotated List Of Snails From Texas And Northern Mexico Collected By C. D. Orchard, E. P. Cheatum

Field and Laboratory

A collection of land and fresh-water shells, principally from central, southern and southwestern Texas counties, with a few lots from Mexico, has been sent to me by Mr. C. D. Orchard, of San Antonio. Each lot was accompanied by ecological data; and since there were many intergrading forms, the following annotated list may be interesting and useful to field zoologists and systematists.

Geographic Factors In The Development Of The Fredericksburg Area, Carol Fritz

Field and Laboratory

As a result of economic stress in Central Europe following the Napoleonic Wars and the industrialization of the Rhine region, the Mainzer Verein-a society of nobles-was organized in Germany in 1844 to direct and protect German emigration. After considering several regions as possible locations for its future colonies, the Society ultimately decided upon an unoccupied section of central Texas. This decision resulted from a favorable report by the Company's agent, Prince Victor von Leiningen, despite the fact that another agent, Count von Boos-Waldeck, advised against settling the Texas area because of the expense of transportation and lack of protection from …

The Spiders Of South Dakota, Allan G. Peterson

Electronic Theses and Dissertations

Spiders constitute the order of Araneida, which is one of the principal divisions of the class Arachnida. The Arachnida also includes scorpions, whipscorpions, pseudosscorpions, harvestmen, mites, and ticks. Some of the distinguishing characteristics of the Araneida are as follows: The head and thorax are consolidated into a cephalothorax. The abdomen is unsegmented and joined to the cephalothorax by a short narrow stalk. There are six pairs of appendages on the cephalothorax: chelicerae, pedipalps with heir basal masticulatory endites, and four pairs of walking legs.

A Zygotic Lethal In Chromosome 1 Of Maize And Its Linkage With Neighboring Genes, R. A. Emerson

Department of Agronomy and Horticulture: Faculty Publications

maize with mosaic red pericarp and cob, here designated by the symbol M-M, crossed with a local inbred strain of maize having white pericarp and cob, W-W, produced in F₁ 21 M-M and 28

W-W plants, not far from the I : I relation expected on the assumption that

the M-M parent was heterozygous for pericarp and cob color, M-M/W-W.

In F₂ and segregating F₃ cultures, however, there were 130 M-M and 64

W-W plants obviously a 2 : I instead of the 3 : I relation expected. Later cultures

A Preliminary Study Of The Vegetative Cover In Spanish Fork Canyon, Utah, Ben S. Markham

Theses and Dissertations

Spanish Fork Canyon is located in central Utah and is part of the Wasatch Mountain range. Since the coming of the white man to this section of country it has been used as a trail. The canyon provides summer range for stock as well as a watershed. Plant densities were determined by the point observation method using series of one-hundred square foot plots. Three areas which have been subject to different grazing uses were studied. The association changes in the canyon are the replacement of sage by slender wheatgrass on the shallow soils and the disclimax condition resulting from over-grazing …
