Streak Mosaic Of Wheat In Nebraska And Its Control, R. Staples, W. B. Allington

Nebraska Agricultural Experiment Station: Historical Research Bulletins

This bulletin reports the results of studies on the epidemiology of wheat streak mosaic under Nebraska conditions. Particular attention is given to the occurrence and certain characteristics of the mite vector of the virus, the relation of weather and other factors to some of its activities, a correlation of certain mite situations with epidemics of the disease, and recommendations for disease control.

Flight Activities Of The Ant Dolichoderus (Hypoclinea) Mariae Forel, Mary Talbot

Faculty Scholarship

Often some reference is made to the "flight" of a .species of ants as if all the males and females left the colony .on one day. W. M. Wheeler, in his 1905 account of the genus Dolichoderus, said .o D. mariae" "August 20 is approximately the date of the nuptial flight oi this species." Today it is generally understood that there are usually a number oi flights. This study shows that D. mariae is conspicuous in this respect.

The Comparative Osteology Of The Trunk Skeleton Of Five Year Classes Of The Golden Shiner, Notemigonus Crysoleucas (Mitchell), Aaron Hathaway O'Bier

Master's Theses

The golden shiner, Notemigonus crysoleucaa, forms a monotypic species in the fish family, Cyprinidae. It is a medium-sized minnow which inhabits ponds and sluggish freshwater streams in North America from latitude; 30°N. to 50°N. In the south its range is restricted to the area east of the Appalachian Mountains. The northern and western part of the range extends to Wyoming and south to the drainages of the Arkansas and upper Ohio Rivers.

Grasslands Of The Great Plains: Their Nature And Use, J. E. Weaver, F. W. Albertson, B. W. Allred, Arnold Heerwagen

Papers of John E. Weaver (1884–1956)

This book is the result of a long-felt need by the authors and their students for a comprehensive survey of the numerous studies that have been made on plains grasslands. From southern Texas far into Saskatchewan the mid and short grasses form a magnificent prairie nearly 2,500 miles in length and approximately 400 miles wide. Kinds of communities, their composition, nature, significance and uses are fully described. Such information is of value not only to students, range technicians, and other professional conservationists, but also to ranchers and other land owners-in fact, to anyone interested in the economy of our midwestern …

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).

Studies On Bucephalid Cercaria Including A New Species From The Dillon Beach Area, Donald Edward Giles

University of the Pacific Theses and Dissertations

The family Bucephalidae is unique in the class Trematoda by virtue of the mouth being situated near the mid-ventral portion of the body. Other characteristics of the family include: haptor near the anterior extremity; a simple, sac-like gut with pharynx and esophagus; genital pore ventral, just anterior to the posterior extremity; gonads posterior and vitellaria species live in the gut of marine and fresh-water fishes. The metacercariae are found encysted beneath the skin or in the nervous system of other fishes serving as second intermediate hosts. Sporocysts and cercariae have been recovered from a variety of lamellibranchs.

Handbook Of Bacteriology For High School Teachers, David Loring Fagle

Dissertations and Theses @ UNI

The study of bacteriology is frequently not included in the high school science curriculum and often, when it is taught, it is dealt with in only a superficial manner. There are various reasons for this. Very often high school science instructors lack training in courses relating to bacteriology and consequently, feel inadequate to handle the topic with their students. Another factor rests with the fact that bacteria are difficult to study without the aid or microscopes with high power objectives. Many high schools lack this equipment. A third factor is that some parents may feel that it may be dangerous …

The Effects Of Antibiotics Aureomycin And Terramycin On The Disease Crown Gall In Tomato Plants, Charles Raymond Anderson

Dissertations and Theses @ UNI

The disease crown gall manifests itself on various woody or herbaceous plants by the formation of tumor-like enlargements at the crown or on other parts or by extensive production of organs (roots, shoots). In both cases the abnormal development is an uncontrolled hyperplast, resulting in tumors or galls of varying sizes and form or in the production of organs, frequently out of normal position and in excessive numbers. Because of the frequent location of the galls on the stem or trunk near or at the ground level, the disease has been known as crown gall. Various other names such as …

Some Photographic Materials And Techniques For High School Biology Teachers, Robert L. Calentine

Dissertations and Theses @ UNI

Biology teachers in the smaller high schools are often confronted with the problem of securing sufficient classroom teaching material: charts, specimens, and reference books. A relatively inexpensive method of obtaining resource material would prove valuable to teachers confronted with this problem. Granting that actual study of specimens is of greater value than indirect methods, it is often helpful to have a supply of supplementary visual aids.

Bulletin No. 379 - Biology And Control Of The Peach Twig Borer (Anarsia Lineatella Zeller) In Utah, Charles J. Sorenson, Farrell H. Gunnell

UAES Bulletins

The peach twig borer, Anarsia lineatella Zeller, sometimes called the peach worm, annually damages peach, apricot, nectarine, prune, and plum orchards in Utah. Many buds and twig terminals are destroyed each spring by the overwintered generation of partially grown larvae. These emerge from their winter quarters almost as soon as host trees begin their spring growth. From the time the fruit becomes about half grown until it is harvested, later generations of twig-borer larvae feed on it causing irregular, gummy cavities which make it unfit for market.

A Taxonomic And Ecological Study Of The Ants On The Campus Of The University Of New Mexico, Tad S. Clements

Biology ETDs

This thesis attempts to indicate some of the ways in which the ants of the campus of the University of New Mexico affect man within the small area of the campus. However, my purpose of doing the study has not been strictly limited by practical considerations. Until now, no systematic study has been made of the Formicidae of the University of New Mexico Campus. Since the habitats produced artificially by man on the University of New Mexico Campus have resulted in favoring certain species of ants not found by the writer elsewhere in the region, the present study is valuable.

Populations Of Linaria (Scrophulariaceae) In Northeastern Texas, Robert Kral

Field and Laboratory

Two native species of Linaria (L. texana Scheele and L. canadensis (L.) Dumort. occur in Texas. The former is common on sandy to sandy clay loams nearly throughout the state; the latter is confined to sandy sites in the central and eastern counties. Both are abundant in recently abandoned fields in east Texas. Mass-collections were made during March and April of 1955, totalling 335 plants (207 L. texana, 128 L. canadensis) in 8 counties of northeastern Texas. Numbers of individuals taken ranged from 3 to 47 at each of 21 locations. Seven contained both species, 4 only L. canadensis, 10 …

A Laboratory Experiment Involving Paper-Chromatography And Statistics, Charles T. Kenner, Joan Schneider

Field and Laboratory

This article suggests a paper chromatographic separation of the dyes in commercial black inks, which has been designed for completion in one 3-hour laboratory period with the use of equipment and solvents found in practically all laboratories. The experiment gives very satisfactory results, and allows the student to become familiar with the general field of paper chromatography and some of the factors which affect Rf values of constituents of mixtures. It also may be used to demonstrate the use of simple statistical tests, if desired.

The Cassia Fasciculata Complex (Leguminosae) In Texas, B. L. Turner

Field and Laboratory

The genus Cassia is represented in Texas by 15 well-marked species. One of these, C. fasciculata, is a highly variable taxon composed of several intergrading infraspecific taxa. The following treatment is the result of several summers' field work combined with distributional data and morphological study of herbarium material. In the present paper it has been necessary to make two new varietal combinations in C. fasciculata. Hence, in conformity with Article 17 of the International Code of Botanical Nomenclature (1952), it seems desirable to give a somewhat detailed account of the distributional and morphological evidence which leads the author to treat …

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 …

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 …

A Study Of The Various Stages Of Corn Foliage And Their Scale Preventing Abilities In Sea Water Evaporators, Arthur J. Rehberger

Bachelors’ Theses

Previous work carried out at Marquette University has proved that seawater evaporator scale can be prevented if such things as dehydrated alfalfa foliage or dehydrated corn, oats, pea and grass foliage are added to the feed seawater.

The object of this work is to determine if the scale preventing ability of corn foliage varies with the maturity of the plant from which it is stripped. Also if the proven scale preventing ability of mature corn foliage changes while it is stored.

A Study Of Spermatogenesis In The Charales, Robert Korn

Bachelors’ Theses

Investigations on the nature of the antherozoid, or male gamete, in the Archegoniates has been of great cytological interest to numerous workers. An apparent consistency of certain characteristics in the antherozoids of the Bryophytes and the Pteridophytes has, also, undoubtably been of value in determining phylogenic relationships.
