The Influence Of Various Soil Factors Upon Potato Scab Caused By Actinomyces Scabies, R. W. Goss
The Influence Of Various Soil Factors Upon Potato Scab Caused By Actinomyces Scabies, R. W. Goss
Nebraska Agricultural Experiment Station: Historical Research Bulletins
Scab, caused by Actinomyces scabies (Thaxt.) Giiss., is a potato disease of major importance in western Nebraska. Seed treatments are effective in controlling seed-borne scab, but it has been shown that even when healthy or treated seed potatoes are used the disease may be very severe because of infection from the soil. Crop rotation will reduce the incidence of the disease, but the fact that potato scab may cause serious loss in soils never before planted to potatoes indicates that there are numerous factors other than the time interval between potato crops which affect the occurrence of the disease. A …

Relation Of Height At Withers And Chest Girth To Live Weight Of Dairy Cattle Of Different Breeds And Ages, H. P. Davis, R. F. Morgan, Samuel Brody, A. C. Ragsdale
Nebraska Agricultural Experiment Station: Historical Research Bulletins
The size of a dairy cow is important from the standpoint of feed consumption and economy of production and also as an indication of the expected size of offspring. The ultimate disposal of dairy cattle is for beef, and the measure of returns is based upon size and condition. A method for the determination of the approximate weights of dairy females, where scales are not available, is needed. Measurements of dairy cattle which show development and skeletal growth by ages in relationship to weight are presented here for four different dairy breeds.

On January 30, 1937, at his home at 3033 Deakin Street in Berkeley, California, Lawrence Bruner, pioneer American economic entomologist and a world authority on grasshoppers and related insects (Orthoptera), as well as the person who more than any other individual was responsible for the organization of the Nebraska Ornithologists’ Union, passed away after a severe illness of a few days that culminated a rather extended period of gradually declining health. It is difficult to epitomize any account of the life accomplishments of this man, because they were so many and varied, and perhaps for this purpose there …

Crow-Waterfowl Relationships Based On Preliminary Studies On Canadian Breeding Grounds, E. R. Kalmbach
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
With the object of obtaining a current insight into the relationship of crows to waterfowl on their breeding grounds, a study was inaugurated in the spring of 1934 and continued through the nesting season of that and the following year. As originally planned, it called for field studies both in Canada and in the northern United States, but drought conditions had so drastically reduced the breeding population of ducks within our borders by the spring of 1934 that, after a futile effort to locate suitable areas in this country, plans were changed and the studies were restricted to Canadian areas …
Diseases Of Upland Game Birds, J. E. Shillinger, L. C. Morley
Diseases Of Upland Game Birds, J. E. Shillinger, L. C. Morley
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
Until recently the diseases of upland game birds received comparatively little specific study, except in a few outbreaks in which serious losses were observed. Though highly destructive, many of these outbreaks were of such short duration that the investigations undertaken were chiefly to learn the cause of death and usually were discontinued when losses were no longer noticeable. It has become increasingly evident, however, that every year great numbers of game birds die of disease, the decreases in their numbers frequently occurring in sections closed to hunting, even though food, cover, and other environmental conditions appear ideal. The disease problems …

Local Bird Refuges, W. L. Mcatee
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
Birds appeal strongly to the interests and affections of mankind. Not only do they charm by their graceful forms, harmonious colors, sprightly actions, and usually pleasing notes, but they have an even more important claim upon our esteem because of their great economic value.
Birds feed upon practically all insect pests. They are voracious, are able .to move freely from place to place, and exert a steady influence in keeping down the swelling tide of insect life.
For economic as well as for esthetic reasons, therefore, an effort should be made to attract and protect birds and to increase their …

Palaeontologic And Geologic Consideration Of Early Man In Nebraska, Erwin Hinckley Barbour, C. Bertrand Schultz
Palaeontologic And Geologic Consideration Of Early Man In Nebraska, Erwin Hinckley Barbour, C. Bertrand Schultz
Bulletin of the University of Nebraska State Museum (1924–2023)
There has been much discussion recently relative to the geologic age of Yuma and Folsom artifacts. The writers submit the following palaeontological and geological data which may aid in a better interpretation of the subject. This paper deals with three localities in Nebraska where Yuma and Folsom implements have been found with extinct mammals; namely, the Scottsbluff Bison Quarry, the Sand Hill blow-out sites, and the Sioux County artifact sites.
Relative Efficiency Of Roots And Tops Of Plants In Protecting . The Soil From Erosion, Joseph Kramer, J. E. Weaver
Relative Efficiency Of Roots And Tops Of Plants In Protecting . The Soil From Erosion, Joseph Kramer, J. E. Weaver
Papers of John E. Weaver (1884–1956)
An increasing realization of the importance of preventing or controlling soil erosion has resulted in numerous scientific investigations. Some of these are concerned with soil characteristics which promote or retard erosivity (Middleton, '30; Middleton et al., '34; Lutz, '34; and Bouyoucos, '35). Many have to do with engineering methods of reducing soil wastage (Bates and Zeasman, '30; Ramser, '30; Roe, '33; and Bartel, '35). But perhaps most were planned to discover the effects of plants in protecting and binding the soil, reducing runoff, and consequent loss of soil and subsoil (Sampson and Weyl, '18; Duley and Miller, '23; Lowdermilk, …

Relative Efficiency Of Roots And Tops Of Plants In Protecting The Soil From Erosion, J. E. Weaver
Department of Agronomy and Horticulture: Faculty Publications
Plant cover, soil and topography are the major factors concerned in the problem of erosion. During the earlier studies, conducted largely by engineers, chief emphasis was placed upon topography. Following extensive work by pedologists, it is now generally conceded that type of soil is an equally important factor. Intensive studies on the effect of plant cover reveal the extremely important role played by plants in holding the soil against the forces of erosion. In this preliminary account of the relative effectiveness of roots as compared to tops in holding the soil in place, the results are based on extensive experiments …

The Utilization Of Nitrogen, Calcium, And Phosphorus By The Growing Chick, C. W. Ackerson, M. J. Blish, F. E. Mussehl
Nebraska Agricultural Experiment Station: Historical Research Bulletins
1. The nitrogen, calcium, and phosphorus content of 127 newly hatched chicks was determined. 2. Thirty newly hatched chicks were fed accurately known amounts of a good chick mash for 60 days. At the end of the period nitrogen, calcium, phosphorus, and fat were determined for each chick. 3. By means of the comparative slaughter test the retention of nitrogen was found to be 37.8 per cent, calcium 43.4 per cent, and phosphorus 27.3 per cent of the respective elements fed. 4. The average gain in live weight per gram of nitrogen fed was 12.0 grams. 5. The rate of …
Some Monogenetic Trematodes From The Galapagos Islands And The Neighboring Pacific, Frank Grose Meserve
Some Monogenetic Trematodes From The Galapagos Islands And The Neighboring Pacific, Frank Grose Meserve
School of Biological Sciences: Dissertations, Theses, and Student Research
Introduction
Trematodes are parasitic, unsegmented, flattened (rarely cylindrical) worms. They have ventral, anterior, posterior or median attachment organs. The sense organs are poorly developed. The mouth is terminal or ventral and subterminal. The intestine is usually forked with or without lateral branches. The animals, with few exceptions, are hermaphroditic. The ovary is usually single. They have one, two, or more testes. The development is direct with only one host in the ectoparasitic Monogenea and indirect in the Digenea which have two or more hosts. The digenetic trematodes usually parasitize vertebrates which serve as their primary hosts and invertebrates (Mollusca) which …

A New Fossil Peccary, Prosthennops Niobrarensis, From Brown County, Nebraska, Edwin H. Colbert
A New Fossil Peccary, Prosthennops Niobrarensis, From Brown County, Nebraska, Edwin H. Colbert
Bulletin of the University of Nebraska State Museum (1924–2023)
During the summer of 1929, the writer, accompanied by Mr. Paul O. McGrew of the University of Nebraska, discovered during the course of excavations for fossil vertebrates in northern Brown County, Nebraska, a fairly complete peccary skull referable to the genus Prosthennops. This skull, due to its several unusual characters, as well as to its fair degree of completeness, would seem to warrant a special and a rather detailed description. Consequently the specimen has been kindly turned over to me by Dr. E. H. Barbour, Director of the Nebraska State Museum, not only for the purpose of the present …

A New Miocene Dog, Mesocyon Geringensis, Sp. Nov., Erwin Hinckley Barbour, C. Bertrand Schultz
Bulletin of the University of Nebraska State Museum (1924–2023)
A field party from the Nebraska State Museum consisting of Messrs. E. L. Blue, Frank Crabill, Loren Eiseley, and C. Bertrand Schultz, on August 28, 1931, was fortunate in finding the remains of a new Mesocyon. This specimen, number 4-28-8-31, the Nebraska State Museum, was found in the Gering formation (lower Miocene), fifteen feet above the Brule, 400 feet west of the road in Redington Gap, near the center of the S. 1/2, sec. 14, T. 19 N., R. 52 W., west of Bridgeport, Morrill County, Nebraska.

Bulletin of the University of Nebraska State Museum (1924–2023)
In February, 1932, while opening a gravel pit to get material for highway construction, the skull, tusks, and mandible of a new longirostral mastodont were found by Robert Arnold on his ranch, Sec. 24, T. 12 S., R. 22 W., 1 1/2 miles due east of Ogallah, Trego County, western Kansas. This point is located about 20 miles west and three miles north of Hays, the seat of the Fort Hays Kansas State College, in the museum of which the above mentioned specimen is mounted and exhibited. When unexpectedly exposed by Mr. Arnold and his associates, the great skull was …
Comparison Of Runoff And Erosion In Prairie, Pasture, And Cultivated Land, J. E. Weaver, Wm. C. Noll
Comparison Of Runoff And Erosion In Prairie, Pasture, And Cultivated Land, J. E. Weaver, Wm. C. Noll
Papers of John E. Weaver (1884–1956)
Soil erosion resulting from runoff water has come to be recognized as a national menace. The determination and evaluation of all factors influencing runoff and erosion are studies of fundamental importance, especially insofar as they may be made to yield information upon methods of control over this insidious tendency of washing away the land.
"Fully 75 per cent of the crop-producing and grazing areas of the United States is sloping enough to set in motion, moderately or violently, these wasteful processes of accelerated soil-removal and excessive runoff. That 35 million acres of formerly cultivated land have been essentially ruined by …
