Streak Mosaic Of Wheat In Nebraska And Its Control, University Of Nebraska-Lincoln Staples, W. B. Allington

Department of Plant Pathology: Faculty Publications

A mosaic of wheat was first observed in Nebraska by Peltier in 1922. According to Haskell and Wood (1923) Peltier found diseased plants in a large number of winter and spring wheat varieties at Lincoln and, in some instances, he successfully inoculated wheat and corn from the juice of infected plants. The temperatures under which Peltier maintained his inoculated plants are unknown and other criteria now employed to characterize the viruses were not utilized. It is probable, however, that he was working with what is now known as wheat streak mosaic virus.

Waterfowl Sex Ratios During Spring In Washington State And Their Interpretation, Paul A. Johnsgard, Irven O. Buss

Papers in Ornithology

Sex-ratio studies have received much attention from research workers in recent years. The contributions of Hochbaum (1944), Petrides (1944) and others have yielded considerable information on sex ratios in waterfowl; Beer (1945) and Yocom (1949) have presented data for the state of Washington. To interpret regional data on waterfowl sex ratios adequately, it is necessary to obtain a series of uninterrupted observations covering the entire migration period of the species concerned. In 1954, an ecologic study was conducted in the Potholes area, Grant County, central Washington (Johnsgard, 1956). During the period February 15 to May 16, sex-ratio data were collected …

The Life Cycle Of Crassiphiala Bulboglossa (Trematoda: Strgeida): Development Of The Metacercaria And Cyst, And Effect On The Fish Hosts, Glenn L. Hoffman

United States Fish and Wildlife Service: Publications

The adult of Crassiphiala bulboglossa was described by Van Haitsma (1925) from the kingfisher, Ceryle alcycon. It can be differentiated from Uvulifer ambloplitis (Hughes, 1927), apparently its closest relative in North America, by the presence of a large bulbous holdfast occupying most of a cup-shaped forebody, and the absence of a ventral sucker. In U. ambloplitis the holdfast is small, the forebody is not cupped, and a ventral sucker is present. These species can be readily identified with the keys given by Dubois (1953).

Early Ceramic Period Sites In Northeastern Nebraska, Raymond S. Price

Department of Anthropology: Theses and Student Research

The Central Plains has become an increasingly important  area of archeological research during the last half century.  The major culture complexes have been identified, the chronological sequences of these cultures have been determined, and  the general framework or Central Plains prehistory has been  outlined. Three main time periods are recognized for the Central Plains on the basis of a combined stratigraphic and  dendrochronological study (Ohampe, 1946). These three general  time divisions are, identified as beginning with the oldest: the Lithic, the Ceramic, and the Historic Periods. The Ceramic Period is further divided into the Early, Middle, and  Late divisions. The …

A List Of Cestode Parasites From California Mammals, Marietta Voge

Harold W. Manter Laboratory of Parasitology: Faculty Publications

This report brings together information on the occurrence and distribution of cestode parasites in California mammals. The original information reported herein, was obtained by students, myself, and other staff members of this university. Although the host-parasite list which follows is far from complete, the dearth of knowledge about the helminth fauna in California seems to justify the publication of relatively few data, in the hope that other workers will be able to use this list as a starting point and add to it.

With few exceptions, the common names of the hosts, as given in the host list, were obtained …

Field Manual Fm 30-16, Technical Intelligence, 26 August 1955, Robert Bolin , Depositor

United States Department of Defense Military Intelligence

This manual outlines responsibilities for technical intelligence at all levels in the Army from the top level to units in the field. It discusses technical intelligence training, processing, and operations.

The modern US Army vision of the technical intelligence developed during World War II. The importance of studying foreign military equipment had become apparent and procedures for collecting and evaluating of equipment had been developed. Technical Intelligence procedures and organizations were refined during the cold war and Korean War. Period.

This manual represents a mature picture of Army technical intelligence as it was in the mid-1959s from the viewpoint of …

Classification Of Oligocene Sediments In Nebraska: A Guide For The Stratigraphic Collecting Of Fossil Mammals, C. Bertrand Schultz, Thompson M. Stout

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

The Chadron and Brule formations constitute the White River Group in Nebraska and adjacent states. The Brule is divided into the Orella and Whitney members. The latter members are referred to the Medial and Late Oligocene (equivalents of the European Stampian and Aquitanian), while-the Chadron is equated with the Early Oligocene (Sannoisian). Each unit in Nebraska is subdivided into three parts (Lower, Middle, and Upper; or A, B, and C for the Chadron and Whitney, and A-B, C, and D for the Orella). Key beds such as fossil soils (paleosols), Purplish White beds, and volcanic ash layers, when considered with …

Pustule Formation By Lactobacilli On Fermented Vegetables, T.L. Thompson, W.E. Engelhard, Hilliard Pivnik

Papers in Microbiology

Genuine dill pickles are the product resulting from the fermentation, predominantly lactic, of cucumbers immersed in a brine containing 3 to 4 per cent salt. The brine also contains dill weed and may contain spices and garlic or extracts of their essential oils. Genuine dill tomatoes are manufactured from green tomatoes by a fermentation similar to that used for pickles (Fabian and Wadsworth, 1944).
Lactobacillus plantarum is commonly associated with the fermentation of pickles (Pederson, 1936), although other lactobacilli and some yeasts undoubtedly play a role. A survery of the literature failed to uncover any reports concerning the microbial flora …

Stachybotrys Atra, An Effective Aggregator Of Peorian Loess, S. C. Downs, T. M. Mccalla, Francis A. Haskins

Department of Agronomy and Horticulture: Faculty Publications

Twelve cellulose-decomposing fungi were tested for aggregating ability with Peorian loess containing ground straw at a concentration of 1%. Of the 12 fungi, Stachybotrys atra was the most effective soil aggregator. Under laboratory conditions used, it produced from 2 to 30 times more aggregation than any of the other fungi tested. Studies were made of the influence of various environmental factors on the degree of aggregation effected by S. atra. An incubation time of 1 week was sufficient for a relatively high degree of aggregation. In comparison, longer periods resulted in only slightly improved aggregation. Varying the temperature between …

Paleosols Of The Oligocene Of Nebraska, C. Bertrand Schultz, Lloyd G. Tanner, Cyril Harvey

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

Prominent paleosol ("buried" or "fossil" soil) complexes occur at the top of the middle Orella, upper Orella, lower Whitney, and upper Whitney in the Brule formation of Nebraska; and at the top of the "Lower Oreodon," "Middle Oreodon," "Upper Oreodon," and "Leptauchenia" beds in the Brule deposits of South Dakota. These paleosols have regional distribution and appear to be of value in stratigraphic correlations. Major faunal breaks seem to coincide with important buried soil zones, thus indicating that certain paleosols actually represent unconformities. Some of the soils were developed on old land surfaces where deposition was practically at a standstill …

Industrial Wastes, Charles E. Renn

United States Environmental Protection Agency: Publications

This paper presents a summary of experiences with a variety of cyanogenic wastes. The work has attempted to evaluate the interaction of waste bearing waters and the environment in terms of waste disposal design requirements. In this, the approach is somewhat more critical than that commonly taken by fisheries biologists, conservationists, and others who have been concerned with the "preventive" aspects of waste disposal.

The first phases of the work were designed to discover the tolerable limits of certain waste components to fresh water fish. This was undertaken in 1950; in the interval the composition of the wastes has been …

Birds Of Jasper National Park, Alberta, Canada, Ian Mctaggart Cowan

Other Publications in Wildlife Management

Jasper Park, with an area of approximately 4 200 square miles, is the largest accessible primeval wildlife sanctuary on this continent and as such its bird lite is of the greatest interest. The meagre available records of earlier conditions indicate that noteworthy changes in the park's avifauna have taken place in the last ,0 years. There can be little doubt that other changes will take place during the years to come. For this reason, then, if tor no other, it seems desirable that as complete a record as possible of the current situation be made, for only against it can …

Mammal Observations At Lower Back River, Northwest Territories, Canada, H. L. Gunderson, W. J. Breckenridge, J. A. Jarosz

University of Nebraska State Museum: Mammalogy Papers

The Back River drains the interior barrens of the Northwest Territories of Canada. According to Blanchet (1930) the river has its headwaters in a high plateau and flows through a sand plain basin (not in accord with conditions of our base camp). The country north of the Back River drainage is of low relief. The river takes a northerly direction for the last one-third of its course. To the east, between the river and Wager Bay, the country is known to be very rugged.

The first known exploration of the Back River, then called the Great Fish River, was by …

Research Notes: Notes On The Life Cycle Of Fibricola Cratera (Trematoda: Strigeida), Glenn L. Hoffman

United States Fish and Wildlife Service: Publications

The life cycle of Fibricola cratera (Barker and Noll, 1915) Dubois, 1932 was reported in 1940 (Cuckler, A. C., Journal of Parasitology 26 (6-Suppl.): 32-33). The writer repeated the life cycle at the University of Iowa in 1948-49 and wishes to add a few observations. Apparently the life cycle of Fibricola texensis Chandler, 1942 (Chandler, A. C., Transactions of the American Microscopical Society 61: 156-167, 1942) is very nearly identical to that of F. cratera. The genus has been reviewed by C. P. Read (Transactions of the American Microscopical Society 67: 165-168, 1948).

Neascus Nolfi N. Sp. (Trematoda: Strigeida) From Cyprinid Minnows With Notes On The Artificial Digest Recovery Of Helminths, Glenn L. Hoffman

United States Fish and Wildlife Service: Publications

During an examination of fish from Turtle River, Arvilta, North Dakota, a new Neascus (larval strigeid) was recovered from the musculature and integument of the northern creek chub, Semotilus a. atromaculatus (Mitchell) and the northern common shiner, Notropis cornutus frontalis (Agassiz). This new species is named in honor of Dr. L. O. NoIf, University of Iowa.

Influence Of Atmospheric And Soil Moisture Conditions On Diurnal Variations In Relative Turgidity Of Potato Leaves, H. O. Werner

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The experimental work reported herein was planned to determine: 1. The extent and nature of the changes of the relative turgidity (R.T.) of leaves of the potato plant during the diurnal cycle. 2. The extent to which R.T. of potato leaves is influenced by atmospheric conditions, soil moisture, variety and age of plants. 3. The extent to which visible evidence of water shortage in leaves is indicative of water loss from them as revealed by R.T. and the extent to which this relationship varies with different varieties. 4. The nature of the relationships between morphological characteristics of leaves and stems …

North American Prairie, J. E. Weaver

Papers of John E. Weaver (1884–1956)

TO MOST AMERICANS, the word "Prairie" suggests either a romantic element in pioneer fiction or a vast expanse of level land which must be crossed in going from one coast to another. But to the botanist, the American Prairie is a wonderfully complex society of living organisms.

This book tells the story of that society-the variety of its inhabitants; the constitution of its several communities; the internal struggles for domination of the society; and the battles of the Prairie as a whole against its two most vicious enemies, drought and overgrazing. Most striking, perhaps, is the story of that portion …

The Growth Of Pathogenic Bacteria In Soluble Oil Emulsions, Hilliard Pivnik, W.E. Engelhard, T.L. Thompson

Papers in Microbiology

Mineral oils, when emulsified with materials such as soaps of petroleum sulfonates, fatty acids, abietic acid or resin, are referred to as soluble oils. These oils, mixed with water, form stable emulsions which are universally employed as coolants and lubricants for drilling, cutting, and grinding of metals. In addition to the emulsifying agent, soluble oils may also contain fatty oils, disinfectants and emulsion stabilizers.
The oils supplied by the manufacturer are sterile, but when mixed with water in the machine shop they support microbial growth (Duffet et al., 1943; Fabian and Pivnick, 1953; Lee and Chandler, 1941; Page and Bushnell, …

Secretion Of Amylase By Rumex Virus Tumors In Vitro, L. G. Nickell, M. K. Brakke

Department of Plant Pathology: Faculty Publications

The secretion of extracellular enzymes by intact cells of higher plants apparently is a rare occurrence. One example of it is the secretion of an extra, cellular amylase by the tissue of a virus-induced tumor from the root of Rumex wetosa L. An amylase is secreted in sufficient quantities by this tissue to enable it to grow as well in vitro on a starch-containing medium as on one containing sucrose.

The Occurrence Of Ornithodiplostomum Ptychocheilus (Faust) (Trematoda: Strigeida) In Fish And Birds, Glenn L. Hoffman

United States Fish and Wildlife Service: Publications

The metacercaria of Ornithodiplostomum ptychocheilush as been reported by Faust (1918; Illinois Biological Monographs 4(1): 1-120) from mesenteries of the squawfish, Ptychocheilus oregonensis (Richardson), and by Hughes and Piszcek (1928; Journal of Parasitology 15: 58-62) and Van Haitsma (1930; Transactions of the American Microscopical Society 49: 140-153) in the northeastern sand shiner, Notropis deliciosus stramineus (Cope). Van Haitsma (1930) found the adults in mergansers, Mergus americanus, M. serrator, Lophodytes cucullatus, and the old squaw duck, Harelda hyemalis. He also reared the metacercaria to the adult in young domestic ducks. Lyster (1940; Canadian Journal of Research 18D: 79-82) reported …

On The Status Of Some Arctic Mammals, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The mammal fauna of arctic Alaska is comprised of about thirty species, most of which are widely distributed. A few of these are essentially nearctic species, having extended their range northwestward during post-Pleistocene time. The majority, however, consists of forms which are either circumboreal in their distribution, or which have closely-related palearctic counterparts-considered specifically distinct hy most North American mammalogists. Sorne of the foremost Old World workers, however, do not agree that Bering Strait constitutes a barrier which effectively separates the Old World fauna from the New.

Studies On The Helminth Fauna Of Alaska. Xiii. Disease In The Sea Otter, With Special Reference To Helminth Parasites, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

During the spring of 1951, the U. S. Fish and Wildlife Service undertook the removal of sea otter, Enhydra lutris (L)., from the Aleutian Island of Amchitka, for the purpose of restocking range from which the animals have long been exterminated. The decision to undertake this activity was influenced by the nature of military operations planned for the island later the same year. The capture and removal of the otter were under the supervision of Mr. Robert D. Jones, Biologist, U. S. Fish and Wildlife Service. Heavy losses among the animals shortly after capture made the venture unsuccessful. Many deaths …

Stream Pollution, Ruth Patrick

United States Environmental Protection Agency: Publications

This paper discusses the various ways in which aquatic organisms may be of use in solving problems associated with waste disposal. Since many state and federal laws set forth that nothing may be discharged that is deleterious to aquatic life, the most expedient way to determine the effect of an effluent is to study the aquatic organisms themselves.

In every river that has not been adversely affected by pollution there is a great variety of aquatic life. These organisms do not represent a great mass of living things, but rather they are organized into an intricately balance systems, often referred …
