Parasites Of Ohio Muskrats, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Parasites of the muskrat (Ondatra zibethica) have received considerable study, but little in Ohio. From March 20, 1943, to March 22, 1945, 70 Ohio muskrat carcasses were examined, most of them being obtained from trappers by Merrill C. Gilfillan, Leader of the Pittman-Robertson Muskrat Project in Ohio. The specimens were from seven localities: Lake Erie Marshes (28); Killbuck Valley Marsh (17, lacking liver and lungs); Walnut Creek (19) and Whetstone Creek (2), (Morrow County); Buckeye Lake (1); Little Scioto River, Marion County (1); and Union County near Marysville (2).

Synoptic Revision Of The United States Scarab Beetles Of The Subfamily Dynastinae, No.1: Tribe Cyclocephalini, Lawrence W. Saylor

Entomology Papers from Other Sources

The important subfamily Dynastinae has for some time been relatively neglected, taxonomically speaking, and only in the past few years have new species been described or the larval characters of many species better characterized. In all collections I have seen,numerous United States species are grossly misidentified, and it is hoped that the present papers will help to rectify this condition.

Ritcher's paper (1944) is an excellent contribution to the immature stages of these insects. His title, however, Dynastinae of the United States, is very misleading, because this paper includes only a small proportion of the described United States species, and …

The Effects Of Penicillin On E. Rhusiopathiae Infected Pigeons, L. Van Es, J. F. Olney, I. C. Blore

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Advantage was taken of an opportunity to study the effects of penicillin on Erysipelothrix rhusiopathiae, the causative organism of swine erysipelas. Owing to the fact that swine cannot readily be infected with erysipelas by artificial methods, pigeons which are highly susceptible to the disease, were selected to serve as experimental animals. It was the purpose of these studies to ascertain whether or not the swine erysipelas bacillus is sensitive to the drug and incidentally to determine the possibility of finding application of penicillin in the treatment of swine.

Effects Of Ddt And Other Insecticides On Several Species Of Potato Insects, Roscoe E. Hill

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Field and laboratory tests conducted in Nebraska showed DDT to be more effective than any other material yet tested against potato insect pests. Records were obtained on tuber flea beetles, Epitrix tuberis, potato psyllids, Paratrioza cockerelli, potato leafhoppers, Empoasca fabae, green peach aphids, Myzus persicae, Lygus elisus, Chlamydatus associatus, Aceratagallia uhleri and Macrosteles divisus. DDT remained effective against potato psyllids and potato leafhoppers under field conditions for a relatively long period of time. Populations of certain beneficial insects, such as Nabis spp., Orius spp. and lady beetles were found to be significantly reduced …

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

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The riboflavin concentrations of twenty-seven kinds of cheeses and cheese spreads were determined by feeding these products to rats whose body stores of riboflavin had been depleted by being fed a riboflavin-deficient diet. Fifteen experiments were made in which 1,223 rats were used. The results obtained varied from 13.5 to 1.2 micrograms of riboflavin per gram of cheese (or spread). The samples of Goat, Velveeta, Mel-0-Pure, and Liederkranz had the highest concentrations of riboflavin while the samples of Cream and Pimento Cream had the lowest concentrations.

Yields And Consumption Of Forage In Three Pasture-Types: An Ecological Analysis, R. W. Darland, J. E. Weaver

Department of Agronomy and Horticulture: Faculty Publications

Native pastures in eastern Nebraska and adjacent states have undergone profound changes as a result of drought. Bluestems (Andropogon) and associated grasses have been thinned and weakened, although recovery has been marked since 1941. In many pastures they were replaced by western wheat grass (Agropyron smithii) or other invading species. In nearly all, wheat grass now occurs in considerable abundance. Kentucky bluegrass (Paa pratensis), into which many overgrazed native pastures had degenerated, was almost completely killed by the drought, or greatly damaged as in western Iowa. Despite these widespread changes, few studies have been made on the relative yields, preferences …

Controlling The Ph Of Cultures Of Penicillium Notatum Through Its Carbon And Nitrogen Nutrition, Albert E. Dimond, George L. Peltier

Department of Plant Pathology: Faculty Publications

A survey of published material reveals relatively little information concerning the nutritional physiology of Penicillium notatum Westl. on synthetic media. Metabolism studies of P. notatum on various media have appeared to be incidental to the more pressing problem of producing penicillin quickly and in quantity. Fleming (1929) originally used a nutrient broth non-synthetic in nature. The Oxford group (Abraham et al., 1941) then adopted a modification of the so-called Czapek-Dox synthetic medium which supplies nitrogen as sodium nitrate and glucose as carbohydrate. Hobby, Meyer, and Chaffee (1942) suggested that brown sugar be substituted for glucose in this nutrient, with …

Poultry Progress: How Long Should A Chicken Live?, F. E. Mussehl

Nebraska Agricultural Experiment Station: Historical Circulars

Increased laying flock mortality has disturbed thoughtful hatcherymen, producers, processors, and research workers for several years, and very properly so, because hens which die before their time serve no useful purpose, except to raise in our minds the question, "Why?"

The Mosquitoes Of Nebraska, H. Douglas Tate, Doris B. Gates

Nebraska Agricultural Experiment Station: Historical Research Bulletins

A survey of mosquitoes in Nebraska was conducted by the Nebraska Agricultural Experiment Station during 1942 and 1943. The object of the study was to determine the species, relative abundance, seasonal occurrence, and principal breeding places of mosquitoes in representative areas of the state. This report presents the results of the survey, and, in addition, some records and observations made in Nebraska by other workers during and previous to initiation of the project.

North American Prairie, J. E. Weaver

Papers of John E. Weaver (1884–1956)

From the highlands of central Mexico across the entire United States and northward into Canada extends the great mid-continental prairie. On the east it is in contact with the deciduous forest. From this central mass the prairie extends westward beyond the Rocky Mountains across Wyoming into eastern Utah, and southwestward through northern New Mexico in to northern Arizona. The Palouse Grasslands occurred in eastern Oregon and Washington, and other parts of the far Northwest. The Pacific Prairie was found in the Great Valley of California, and the-Desert Plains Grassland still occupies much of southern Arizona and New Mexico and southwestern …

Recovery Of Midwestern Prairies From Drought, John E. Weaver

Papers of John E. Weaver (1884–1956)

The long period of desiccation, which began in 1934, finally terminated in 1940. The western portion of True Prairie was greatly decimated and a veritable mosaic of types of vegetation resulted. These ranged from well-preserved relict communities of bluestems (Andropogon) to mixed stands of grasses on nearly bared soil, but included communities of western wheat grass (Agropyron smithii) , short grasses (Bouteloua gracilis and Buchloe dactyloides) , needle grass (Stipa spartea), and prairie drop seed (Sporobolus heterolepis) . These types varied in size from a few square rods to many …

Nitrate Production As Affected By Grain-Crop Residues On The Surface Of The Soil, T. M. Mccalla, J. C. Russel

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The purpose of this bulletin is to present the data on nitrate contents and nitrate production in tests where straw or stalk residues were left on the surface through subsurface tillage, as compared with check treatments where these residues were plowed under or were absent. Nine of these tests were at Lincoln, Nebraska, and one was at the Hastings, Nebraska, Hydrological Project. Two tests were conducted in 1939, four in 1941, and four in 1942.

Food From The Sea: Fish And Shellfish Of New England, Rachel L. Carson

United States Fish and Wildlife Service: Publications

Millions of Americans are developing new wartime food habits, trying foods they once neglected, turning to alternates for long familiar products. For everyone of the ten fish or shellfish that make up mere than four-fifths of New England's catch there are seven species little known or utilized, many of which could provide tasty and nutritious foods. Turning to these under-utilized species will conserve food resources by lifting the burden of over-exploitation from such fishes as cod and haddock and will augment dwindling supplies of protein foods. Exploring the seafood markets for unfamiliar species rewards the housewife and her family with …

Missourian Triticites Of The Northern Mid-Continent, Benjamin H. Burma

Department of Earth and Atmospheric Sciences: Faculty Publications

The tendency toward fine discrimination in fusulinid species has made necessary standardization in their study. Theories and practices of fusulinid study are herein discussed in some detail. Four new species of Triticites are described from the Missouri series of the Pennsylvanian system; one species from the Virgil series and two froim the Missouri are redescribed, and the characters of the other five known Missourian species from the northern mid-Continent are shown in graphs, thus bringing together the known Missourian species. Finally consideration is given to the ontogeny and phylogeny of the group.

Vegetation Of The Northern Part Of Cherry County, Nebraska, William L. Tolstead

Conservation and Survey Division: Faculty and Staff Publications

Agricultural practices in the Great Plains of North America are now in a period of adjustment from a traditional agriculture initiated by pioneer farmers to a grazing economy based upon potentialities of climate and soil. The attainment of a proper system of land use has been retarded in many localities by the lack of definite information concerning the vegetation and its indicator significance. In this study of the vegetation of Cherry County, Nebraska, the interrelations between the plants and their environments are discussed, the dominant species are described, and changes in grasslands caused by seasons, grazing, and climatic cycles are …

This paper presents fifteen pollen profiles from as many peat deposits in Illinois, Indiana, Michigan, and Ohio, only two of which--Bucyrus and Mud Lake (Ohio)--have been previously published. These profiles have been prepared to show only the relative fluctuations of eight forest genera and one family, Betulaceae.

One Hundred Studies Of The Calcium, Phosphorus, Iron, And Nitrogen Metabolism And Requirement Of Young Women, Ruth M. Leverton, Alice G. Marsh

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The present study was undertaken to add appreciably to the data available on the metabolism of calcium, phosphorus, iron, copper, and nitrogen of young women on their customary self-chosen diets. It was planned to use the figures for the retentions or losses of these dietary essentials which occurred at various levels of intake to determine the requirement of the subjects and to evaluate the adequacy of present adult dietary standards for young women. The fact that the girls were living on self-chosen diets warrants emphasis. A large proportion of the subjects were doing light housekeeping and brought much of their …

A Review Of The Daimonelix Problem, C. Bertrand Schultz

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

THE first paleontological expedition of the University of Nebraska State Museum was organized in the summer of 1891 and was led by Erwin H. Barbour, now Director Emeritus of the Museum. The most important and interesting discoveries made during the season were some very peculiar spiral fossils called by the field party "Devil's Corkscrews," or Daimonelix,l which were found in the Miocene deposits near Harrison in Sioux County, Nebraska. During the fifty years that have intervened scientists have tried to determine the origin of these strange forms. Several controversies arose, and although various theories have been proposed, none as yet …
