Increasing Phosphorus Concentration In Lupin Seed Increases Grain Yield On Phosphorus Deficient Soil, Mike D. Bolland, Blakely Paynter, Mike Baker

Grain and Other Field Crops Research Articles

In a field experiment on a phosphorus (P) deficient soil in south-western Australia, lupin seed ( Lupinus angustifolius cv. Danja) of the same size (157 mg/seed) but with 2 different phosphorus (P) concentrations in the seed (2.0 and 2.8 g P/kg) was sown with 4 levels of superphosphate (5, 20, 40 and 60 kg P/ha) drilled with the seed in May 1988 to examine the effect of seed P concentration on subsequent dry matter (DM) and grain yields. Increasing the amount of superphosphate applied from 5 to 60 kg P/ha almost doubled yields. In addition, lupins grown from seed containing …

Effect Of Disulfiram On The Urinary Excretion Of 5-Hydroxytryptophol And 5-Hydroxyindoleacetic Acid In Subjects Consuming Serotonin Rich Foods, Amy G. Tordecilla

Loma Linda University Electronic Theses, Dissertations & Projects

The effect of disulfiram and/or serotonin rich foods (SRF) on the urinary excretion of 5-hydroxytryptophol (5-HTOL) and 5-hydroxyindoleacetic acid (5-HIAA) in normal male subjects was investigated. Urine collections were obtained on 1) regular serotonin free diet, 2) SRF, 3) serotonin free diet with disulfiram, and 4) SRF with disulfiram. Urinary excretion of 5-HTOL in ug/gm creatinine during disulfiram administration was 112.0 ± 24.1. Five HTOL (ug/gm creatinine) with disulfiram and SRF increased to 1532 ± 352.0 (p < 0.001). Five-HIAA (mg/g creatinine) before and after SRF was 3.4 ± .44 and 33.1 ± 6.1 respectively, p < 0.001. With disulfiram and SRF the excretion of was 24.2 ± 3.2 mg/g creatinine which was significantly greater than when on the regular diet (p < 0.001) than the excretion on SRF alone (p < 0.05)

Key words: Disulfiram, serotonin, 5-hydroxytryptophol, 5-hydroxyindoleacetic acid, urinary excretion, high performance liquid chromatography, alcoholism

Frequency-Dependent Seed Dispersal By Ants Of Two Deciduous Forest Herbs, Brent H. Smith, Catherine E. De Rivera, Cara Lin Bridgman, John J. Woid

Environmental Science and Management Faculty Publications and Presentations

Two co—occurring deciduous forest myrmecochores, Asarum canadense and Jeffersonia diphylla, release their seeds at approximately the same time, and therefore potentially compete for ants as dispersers. Within a single woodlot, we placed seeds of both species inside a dense Jeffersonia population away from Asarum plants, inside a dense Asarum population away from Jeffersonia plants, and in a site where plants of neither species occurred. No preference was exhibited by ants where natural populations were absent. Preference at the other two sites was frequency dependent: ants preferred seeds of the introduced species. Species preferred by ants have higher seed and …

Changes In The Esophageal Epithelium In Rabbits Treated By Cis-Dichlorodiammineplatinum As Studied By Electron Microscopy, M. Albertsson, C. -H. Hakansson, M. Palmegren

Scanning Microscopy

The esophageal mucosa of the rabbit was investigated after a single dose of 5 mg Cis-Dichlorodiammineplatinum (Cis-DDP). Specimens were taken for scanning electron microscopy, transmission electron microscopy, and light microscopy. Examination was performed daily for 20 consecutive days. A cytotoxic effect was observed already the first day after injection with an intracellular oedema. Thereafter the height of the esophageal epithelium and the basal cell layer steadily decreased to a minimum day 11. This parallels the damaged microridges and an increased cell loss as revealed by scanning electron microscopy. At the end of the observation period the esophageal mucosa had completely …

The Effect Of 10 And 20 Gy Single Dose Irradiation On The Esophageal Mucosa Of The Rabbit. An Electron Microscopic Study, C. H. Hakansson, M. Albertsson, M. Palmegren

Scanning Microscopy

The mucosa of rabbit esophagus was irradiated with single doses of 10 and 20 Gy respectively. Specimens were taken for scanning electron microscopy (SEM), and light microscopy investigations. Examinations were made 1-14 days after 10 Gy and 1-17 days after 20 Gy. Irradiation resulted in edema during the first days. The thickness of the epithelium was at its lowest value around day 5 after the administration of 10 Gy, and on days eight to ten after the administration of 20 Gy. Damage of the epithelium surface, as scored on SEM micrographs, was most pronounced on days eight to eleven after …

Can Genetically Engineered Crops Become Weeds?, Kathleen H. Keeler

School of Biological Sciences: Faculty Publications

There are significant differences if the distribution of weedy characteristics among weeds, normal plants, and crops. The world’s most serious weeds possess on the average 10 or 11 of these characters, a random collection of British plants have an average seven of the traits, and crop plants only five. For the average crop to become as “weedy” as the average weed, it would need to acquire five weedy traits. Even using the unlikely assumption that those traits are single loci in which a dominant mutation would provide the weedy character, this would require the simultaneous acquisition of five gene substitutions. …

Changes In Caloric Content As A Result Of Sub-Lethal Stress In Neanthes Virens (Sars), Phyllis J. Friello

Biological Sciences Theses & Dissertations

Neanthes virens were subjected to a toxicity test with 1.8, 3.4, 6.7 and 11.0 mg/1 Cd²⁺. Worms were withdrawn on Days 1, 4, 7, 10 and 14 from each of five replicate tanks and their caloric content determined by bomb calorimetry. Analyses of variance and covariance showed no significant differences in worm caloric content with withdrawal day or cadmium concentration.

In a second experimental series, a sediment toxicity test with Neanthes virens was conducted in contaminated sediments from two sites, as well as reference sediments from a control site. Caloric content of the worms was measured by bomb …

Population Dynamics And Management Of Deer In Wisconsin, Keith R. Mccaffery

Wildlife Damage Management Conference

Management of deer in Wisconsin is affected by a combination of biological and environmental factors. In the Northern Forest, winter severity dramatically affects annual survival and recruitment. However, deer density goals here are above "I" carrying capacity. Thus, minor errors in harvest management are in part compensated by herd responses. Deer in the farmland areas of the state are maintained at goals that for the most part are below "I" carrying capacity. Errors in harvest management are magnified in farmland because herd responses are not compensatory. Therefore, the harvest quotas for antlerless deer must be more precise in our farmland …

Fertility Control As A Tool For Regulation Of Wildlife Populations, U. S. Seal

Wildlife Damage Management Conference

Biological control of reproduction and fertility is a normal part of the life history of all organisms. Control mechanisms allow timing of reproduction with respect to age, time of day, season, and other periodic environmental events. Further modulation can occur with variations in temperature, rainfall, nutrition, and health status. Interactions with other members of the species, ranging from pherohormonal stimulation of estrus to social delay of puberty and breeding to infanticide, provide further constraints upon fertility and recruitment. All of these processes ultimately act through molecular neuroendocrine mechanisms that are under genetic control and are subject to natural selection and …

Dietary Protein Deficiency And Mycobacterium Bovis Bcg Affect Interleukin-2 Activity In Experimental Pulmonary Tuberculosis, David N. Mcmurray, C. L. Mintzer, R. A. Bartow, Rebecca D. Parr

Faculty Publications

Inbred strain 2 guinea pigs were vaccinated with Mycobacterium bovis BCG or were left unvaccinated. They were maintained for 6 weeks on defined, isocaloric diets containing either 30% (control animals) or 10% (animals receiving low protein) ovalbumin as the sole protein source. Animals were challenged by the respiratory route with a low dose of virulent M. tuberculosis H37Rv and killed 4 weeks later. Protein-malnourished animals were not protected by previous vaccination with BCG. Lymphocytes isolated from various tissues were tested in vitro for proliferative responses to mitogen (concanavalin A) and antigen (purified protein derivative [PPD]), production of interleukin-2 (IL-2), and …

Agricultural And Food Policy Decisions: A 1989 Perspective From South Dakota's Agricultural Producers, Larry Janssen

Economics Research Reports (1969 - 2017)

Federal government policies greatly affect farmers and ranchers. Most South Dakota farmers and ranchers favor proposals to retain present commodity programs or to gradually eliminate commodity programs. Most producers favor a variety of proposals to reduce trade barriers and liberalize world trade, but are reluctant to give up existing trade barriers. Most producers favor an increased Federal role in environmental programs related to soil conservation and water quality. These are key findings from a 1989 statewide survey of South Dakota farmers and ranchers opinions on agricultural policy issues.

Bulletin 4133 - Fungal Diseases Of Pasture Legumes In Western Australia, M. J. Barbetti

Bulletins 4000 -

Subterranean clover (Trifolium subterraneum L.) is the most important annual pasture legume in Western Australia, forming the basis of some 6.5 million ha of annual pastures. The success of subterranean clover may be attributed to its ability to increase soil fertility as a consequence of nitrogen fixed, to withstand heavy grazing, to control soil erosion and, with some cultivars, to tolerate waterlogging. Fungal diseases have been a major limitation to the productivity of subterranean clover, affecting both the amount of plant matter and the quantity of seed produced.

Annual medic (Medicago spp., in particular M. polymorpha L.) is also an …

A Comparison Of Chemical Composition & Fermentation Patterns Of Alternative Silages To Whole Plant Corn Silage, Susan Fox

Masters Theses & Specialist Projects

A comparison of the relationship of fermentation to chemical composition was made for forages which were wilted and ensiled at 35 to 45 percent dry matter. Trial I consisted of three forages ensiled in October, 1981: interseeded soybeans and grain sorghum. whole plant corn with added anhydrous ammonia, and whole plant corn with shelled corn added at a rate of 150 kg/t of fresh forage. Trial II consisted of two forages ensiled in 1982: interseeded soybeans and pearlmillet, and wheat. Temperatures of fermentation were collected, and chemical composition during the first 25 days of fermentation analyzed.

Production data were also …

University of Nebraska State Museum: Mammalogy Papers

Not long ago we developed a convenient, inexpensive, non-harmful way to learn about the secret lives of small nocturnal mammals. The technique allows us to follow trails made by rodents and to find where they have foraged, what they have eaten, and where they have their burrows. This method involves the use of a fine, nontoxic powder that fluoresces under black light. After setting traps and capturing the animals alive, we gently dust them in the fluorescent powder. The powder, used to make fluorescent paint, comes in different colors. It is especially important that the powder is non-toxic because killing …

The Composition And Concentrations Of Cyanobacteria In The North Landing River, Virginia And Upper Currituck Sound, North Carolina, Sonja E. Midgette

Biological Sciences Theses & Dissertations

A 12 month study of cyanobacteria composition and concentrations in the North Landing River and upper Currituck Sound was conducted from March 1986 to February 1987. Epifluorescence microscopy and the fluorochrome proflavin were used to determine cell concentrations and vertical, station to station and seasonal distribution of these cells. Cyanobacterial assemblage patterns were coupled with pH, temperature, salinity and water transparency readings.

Cyanobacteria were found to be a persistent and prolific phytoplankton component of both the river and upper sound. For a comparison of vertical distribution for each station, an analysis of variance for. two groups of equal size was …
