Western Ironweed: Research On Anatomy, Physiology, Life History And Control, M. K. Mccarty, C. J. Scifres

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Western ironweed (Vernonia baldwini Torr.) is a member of a widespread and diverse genus. The genus is characterized by perennial herbs and shrubs. Weaver and Darland listed the increase of western ironweed, at one time sparsely distributed, as an indication of degeneration of the true prairie. They described the invasion, spread, and ultimate dominance of western ironweed in many pastures after the drought years. Weaver measured ironweed roots to a depth of 11 or 12 ft., and remarked that it was one of "the most abundant and worst weeds in native pastures derived from the true prairie." Research has …

Bovine Testicular Antihyaluronidase In Rabbits: Production And Purification, Gerald Fine, Sheikh M. Saeed, Gerald A. Logrippo

Henry Ford Hospital Medical Journal

An antibody chemically and immunologically active against bovine testicular hyaluronidase was produced in rabbits by injecting them with purified hyaluronidase in complete Freund's adjuvant. Nonspecific antibodies, reacting with human and bovine proteins which had little or no hyaluronidase activity, were also detected by the double agar immunodiffusion technique using antiserum against these proteins. After absorption of the antiserum with bovine heart and liver and removal of the precipitation bands against human and bovine tissue proteins, the antiserum inhibited the chemical activity of the purified hyaluronidase and exhibited immunologic activity against the purified hyaluronidase as shown by the agar double immunodiffusion …

Calf Diarrhea (Scours): Reproduced With A Virus From A Field Outbreak, C. A. Mebus, N. R. Underdahl, M. B. Rhodes, M. J. Twiehaus

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Neonatal calf diarrhea typical of that seen in field cases was produced in colostrum-deprived calves by inoculating either feces or bacteria-free filtrates via the duodenum, orally, or by a spray (aerosol). Three calves, kept free of E. coli, developed severe diarrhea following inoculation with a bacteria-free filtrate. Intense fluorescence in the epithelium of sections of small intestine from two experimental calves was observed following staining with ftuorescein-labeled gamma globulin produced with viral antigen prepared from the feces of two experimental diarrhetic E. coli-free calves. Fluorescing cells were also present in the feces of experimental and field cases of neonatal …

Preferential Food Habits Of Aplodontia Rufa, Lennis Orville Allen

All Master's Theses

In summary, the findings of this study are that the mountain beaver does exhibit preferences in his food habits. It selects for food just less than one-half of the available plant species. Three species are preferred over all others selected for food, those species being sword-fern, salal, and brake-fern.

An Analysis Of Gene-Enzyme Variability In Natural Populations Of Drosophila Melanogaster And D. Simulans, Stephen J. O'Brien, Ross J. Macintyre

Biology Faculty Articles

Nine populations of D. melanogaster and two populations of D. simulans were analyzed for polymorphism in 10 gene-enzyme systems by the technique of gel electrophoresis. In the eight natural populations of D. melanogaster, an average of 54% of the enzymes were polymorphic, and the average heterozygosity was 22.7%. An experimental population of D. melanogaster, which has been maintained in a laboratory cage for 20 years, showed levels of polymorphism equivalent to those of natural populations. The D. simulans populations had much less variability. The possible factors involved in maintaining these polymorphisms are discussed.

Food Preference As A Factor In Distribution And Abundance Of Phoetaliotes Nebrascensis, K. P. Pruess

Department of Entomology: Faculty Publications

Western wheat grass, Agropyron smithii, was the plant most frequently ingested by Phoetaliotes nebrascensis (Thomas) in 4 of 5 habitats and was preferred in all. All grasses were eaten to some extent; nonpreferred plants may support populations in otherwise suitable habitats. Most forbs were unattractive but all tested species of Cichoriaceae were acceptable. Plant-finding was by random searching; selection was made only after contact through the mouthparts. While habitats in which preferred hosts were more abundant had higher grasshopper populations, annual changes in grasshopper abundance within a habitat were independent of abundance of primary food plants.

Effect Of Relative Humidity At 23 C On Egg Eclosion In Two Species Of Pyralid Moths, William P. Morrison

Biology ETDs

Desiccation resistance in eggs of the Indian-meal moth, Plodia interpunctella, and the bluegrass webworm, Crambus teterrellus, was compared. Decapitation was used to obtain eggs for humidity studies. In both species decapitated females showed a slightly higher incidence of infertile eggs, as well as of fertile eggs which did not eclose, than occurred in eggs collected from nondecapitated females. Eggs of P. interpunctella are relatively resistant to desiccation. This moth is a pest of stored grains and tends to oviposit in areas of low humidity. In laboratory tests more than 95% of the fertile eggs eclosed at each of the nine …

Behavior Of Pesticides In Plants, Logan A. Norris

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

A number of chemicals of diverse characteristics have arbitrarily been classed together on the basis of their use and given the descriptive name "pesticides. " An unfortunate aura of mystery has developed about these chemicals. However, there is nothing unique or mysterious about the chemicals we refer to as "pesticides." Like other chemicals, they have properties which can be accurately measured; they obey all the laws of physics, chemistry, and biology.

Meteorological Factors Controlling The Emergence Of The Eastern Spadefoot Toad, Scaphiopus Holbrooki Holbrookii Harlan, Larry Judy

Theses, Dissertations and Capstones

Scaphiopus holbrooki holbrookii, the Eastern Spadefoot, can exist in an area for many years before it is detected. Its apparent scarcity can be explained by its secretive, fossorial habitat, protective coloration, and nocturnal behavior. Spadefoots are present at the surface locally in small numbers on any one night. They emerge only when conditions are optimum. One authority has suggested that temperature, moisture, and barometric pressure exert control over emergence.

It was the purpose of this research to discover the most important meterorological parameters and investigate how they control the behavior of Scaphiopus.

Initially the response, emergence to breed was distinguished …

Development Of Vascular Connections Between Lateral Buds And Main Stem In Some Decapitated Plants, Syed Mushtaq Husain, Albert J. Linck

Journal of the Minnesota Academy of Science

After decapitation of pea plants, with resultant growth of lateral buds, the thickness of vascular tissue appeared to be correlated with the growth rate of buds. Basal lateral shoots had better developed vascular strands than buds on upper parts of the plants. IAA application retarded growth of the lateral buds and inhibited their vascular connections, but all lateral buds eventually grew in spite of the IAA application.

A Disc Electrophoretic Procedure For Separating Proteins Of Marchantia Polymorpha: Esterases., Jerome Anaya, Donald J. Kraft

Journal of the Minnesota Academy of Science

Extracts from Marchanlia polymorpha were used in the development of a disc electrophoretic procedure for the separation of proteins. Dialyzed and fresh extracts were found to produce best resolution when electrophoresed in Tris-Glycine buffer (pH 8.3) and 50 millamps current for 45-60 minutes. The esterase enzyme system was used as an indication of separation. Significantly, 5 bands were detected in induced thalli attesting to the sensitivity and application of this method to developmental studies.
