Revised Checklist Of North American Mammals North Of Mexico, 1979, J. Knox Jones Jr., Dilford C. Carter, Hugh H. Genoways Dec 1979

Revised Checklist Of North American Mammals North Of Mexico, 1979, J. Knox Jones Jr., Dilford C. Carter, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Faunal checklists provide useful ready references for many kinds of endeavors, both in the laboratory and in the field, and are particularly helpful to students. Since publication more than four years ago of a "Revised checklist of North American mammals north of Mexico" (Jones et al., 1975), demand for that list has exceeded the supply set aside for general distribution; additionally, systematic studies of mammals published since 1974 necessitate changes in the list. Primarily for these reasons, a newly revised checklist of mammalian species occurring in the Nearctic to the north of Mexico is here presented. As in this and …


Respiratory Patterns And Oxygen Uptake In The Garter Snake, Thamnophis Elegans, James Whitney Hicks Dec 1979

Respiratory Patterns And Oxygen Uptake In The Garter Snake, Thamnophis Elegans, James Whitney Hicks

Biology ETDs

Eight garter snakes, Thamnophis elegans, were collected in northern New Mexico during July and August. The snakes were kept in an environmental chamber and were entrained to a 141 (0630-2030 h) / 10D (2030-0630 h) cycle for five weeks at 25 C. Ventilation was monitored with a head/body plethysmograph. Pulmonary oxygen uptake was measured by open-system respirometry. Heart rate was recorded with electrodes implanted subcutaneously, bi-lateral to the heart. Ventilation, oxygen uptake and heart rate were measured simultaneously at 25+-1 C. All measurements were recorded continuously for 48-96 hours. As well as investigating the diurnal rhythms of ventilation, oxygen uptake …


Distribution Of Plutonium In Beagle Dog Liver, Jeffery M. Gearhart Dec 1979

Distribution Of Plutonium In Beagle Dog Liver, Jeffery M. Gearhart

Biology ETDs

Plutonium that reaches the systemic circulation by inhalation, ingestion or through cuts or abrasions is preferentially deposited in the liver and bone. Liver cancer may be an important late effect of this deposition. This study was designed to provide improved quantita­tion of the distribution of plutonium deposited in liver as a result of gradual introduction into the blood by absorption from the lung, com­pared with the immediate introduction by intravenous injection of a soluble form. In this study, Beagle dogs were exposed to an aerosol of 280Pu02 or an intravenous injection of 238Pu or 239Pu-citrate. Animals …


Variation In Pappogeomys Castanops (Geomyidae) On The Llano Estacado Of Texas And New Mexico, Robert C. Dowler, Hugh H. Genoways Dec 1979

Variation In Pappogeomys Castanops (Geomyidae) On The Llano Estacado Of Texas And New Mexico, Robert C. Dowler, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Nongeographic and geographic variation in the yellow-cheeked pocket gopher, Pappogeomys castanops, were analyzed in specimens collected in northwestern Texas and eastern New Mexico. Univariate and multivariate methods of analysis were utilized to assess variation in morphometric characters among 12 samples of P. castanops. Because of significant variation with age, only adult specimens were used in analyses. Adult males were significantly larger than females in all 13 characters studied. Our analyses of geographic variation reveal that those specimens previously assigned to the subspecies P. c. simulans are not sufficiently distinct to warrant subspecific designation.


Predation Of Upland Game And Its Management, Roger Wells Dec 1979

Predation Of Upland Game And Its Management, Roger Wells

Great Plains Wildlife Damage Control Workshop Proceedings

There is probably no greater topic that elicits greater emotion in public wildlife discussions than that of predation. A variety of groups each with their own particular special interest surround the topic.

Some advocate complete protection of predators on the premise that their activities merely result in a "balance of nature." The opposite viewpoint argue just as strongly for the total elimination of Predators of valued wildlife in order to have greater number for man's enjoyment.

Effect Of Diet On Aerobic Performance, Maureen Hall Fennerty Dec 1979

Effect Of Diet On Aerobic Performance, Maureen Hall Fennerty

Student Work

Aerobic performance is affected by a number of physiological, psychological, sociological and environmental factors (Astrand, 1977). Among the many physiological factors nutrition plays an important part. However, when considering what constitutes a balanced diet, nutritionists express varying opinions as to what percentage of protein, fat and carbohydrate should be included for the general populace and the athlete. Mayer and Bullen (1960) in their review of literature on nutrition and athletic performance concluded a balanced diet is adequate for the athlete.

Pagurapseudes (Crustacea: Tanaidacea) In Southeastern Florida: Functional Morphology, Post-Marsupial Development, Ecology And Shell Use, Charles Messing Dec 1979

Pagurapseudes (Crustacea: Tanaidacea) In Southeastern Florida: Functional Morphology, Post-Marsupial Development, Ecology And Shell Use, Charles Messing

Oceanography Faculty Theses and Dissertations

Members of the genus Pagurapseudes occupy vacant microgastropod shells. Functional and behavioral convergence with paguridean decapods (hermit crabs) is treated using a combination of gross morphological, histological and scanning electron microscopic analyses, as well as observations of living animals. Post-embryological development is described and compared with that of other tanaidaceans. The proposed life history differs from that of other tanaidaceans in several respects and is the first described for any member of the suborder Monokonophora based on investigations using experimentally reared specimens. Variations in a population over the course of 1.5 years are discussed as are apparent habitat preferences. Preferences …

Mechanism Of Decarboxylation Of Glycine And Glycolate By Isolated Soybean Cells, David J. Oliver Dec 1979

Mechanism Of Decarboxylation Of Glycine And Glycolate By Isolated Soybean Cells, David J. Oliver

David J. Oliver

Isolated soybean leaf mesophyll cells decarboxylated exogenously added [1-14C]glycolate and [1-14C]glycine in the dark. The rate of CO2 release from glycine was inhibited over 90% by isonicotinic acid hydrazide and about 80% by KCN, two inhibitors of the glycine to serine plus CO2 reaction. The release of CO2 from glycolate was inhibited by less than 50% under the same conditions. This indicates that about 50% of the CO2 released from glycolate occurred at a site other than the glycine to serine reaction. The sensitivity of this alternative site of CO2 release to an inhibitor of glycolate oxidase (methyl-2-hydroxy-3-butynoate) but not …


A Study Of The Relative Effectivness Of Four Insolubilizing Agents In Starch-Latex And Protein-Latex Coatings, Steven D. Bennett Dec 1979

A Study Of The Relative Effectivness Of Four Insolubilizing Agents In Starch-Latex And Protein-Latex Coatings, Steven D. Bennett

Paper Engineering Senior Theses

The process of offset lithography requires several unique characteristics in paper. One of these is an ability in the sheet surface to accept water without deteriorating. Offset coatings commonly use starch and protein in their binder systems. These adhesives are inherently water sensitive. The characteristic of water resistance in coated grades can be obtained through the use of crosslinking agents. Among the more commonly used are unreaformaldehyde, melamine-formaldehyde, and glyoxal. A more recent development involves the use of ammonium zirconium carbonate.

Through the years many studies have examined the effects of various insolubilizing agents in starch coatings. Most of these …

Patterns Of Fetal Lamb Regional Cerebral Blood Flow During And After Prolonged Hypoxia, Stephen Ashwal, John S. Majcher, Nestor Vain, Lawrence D. Longo Dec 1979

Patterns Of Fetal Lamb Regional Cerebral Blood Flow During And After Prolonged Hypoxia, Stephen Ashwal, John S. Majcher, Nestor Vain, Lawrence D. Longo

Loma Linda University Electronic Theses, Dissertations & Projects

[Abstract not included]

Speculation: In the fetal lamb during prolonged intrauterine hypoxia, total and regional cerebral blood flows increase to the same extent without evidence of preferential shunting to critical brainstem or subcortical areas. Neuropathologic studies have indicated relative sparing of these areas during similar animal experimental or human neonatal conditions. This suggests that the pattern of hypoxic ischemic insult to the neonatal central nervous system associated with asphyxia may differ from that produced by hypoxia alone. In addition, during asphyxia these pathologic changes may result primarily from hypotension and decreased regional cerebral blood flow, or from regional metabolic derangements …


The Life History, Behavior, And Ecology Of Etheostoma Sagitta (Jordan And Swain), John Eldon Lowe Jr Dec 1979

The Life History, Behavior, And Ecology Of Etheostoma Sagitta (Jordan And Swain), John Eldon Lowe Jr

Masters Theses

The life history, behavior, and ecology of Etheostoma sagitta (Jordan and Swain) were studied in the Cumberland River system in Tennessee. Diving equipment was utilized in making observations on macrohabitat, microhabitat, distribution, seasonal and diurnal activity, feeding behavior, migration, territoriality, associated species, competition, and population density and structure. Courtship, reproductive behavior, and diurnal activity were studied primarily in an experimental raceway. Feeding behavior and territoriality were studied in the raceway and in a 77.5-1. (20-gal.) aquarium. Parasites, longevity, age and growth, ova numbers and maturation, sex ratios, and food habitats were examined in the laboratory.

Etheostoma sagitta was found in …


Comparison Of Electron Microscopy And Immunoelectron Microscopy With The Enzyme-Linked Immunosorbent Assay For The Detection Of Rotavirus And Antibody To The Virus, Maria Del Carmen Monedero Dec 1979

Comparison Of Electron Microscopy And Immunoelectron Microscopy With The Enzyme-Linked Immunosorbent Assay For The Detection Of Rotavirus And Antibody To The Virus, Maria Del Carmen Monedero

Biology ETDs

Rotavirus has been shown to be an etiological agent of acute gastroenteritis, in human infants and children and in young animals, such as mice, calves, lambs, and pigs. Bovine, porcine, simian (SA-11) rotaviruses and the “0” agent (sheep, goat) have been cultivated in cell cultures. To date the human rotavirus has been propagated only in fetal intestine organ cultures, where it has lost infectivity after a few passages. For this reason, methods of detection of the human rotavirus and serological tests for antibodies to it have been difficult to develop. At the present time there are several techniques that are …


Cyanogenesis In Indiangrass Seedlings, Francis A. Haskins, H. J. Gorz, Kenneth P. Vogel Dec 1979

Cyanogenesis In Indiangrass Seedlings, Francis A. Haskins, H. J. Gorz, Kenneth P. Vogel

Department of Agronomy and Horticulture: Faculty Publications

In a study of seedlings of 72 entries representing 39 species, 14 genera, and 2 tribes of grasses, only entries of the genus Sorghastrum were found to contain the cyanogenic glucoside, dhurrin [(S)-p-hydroxymandelonitrile β-D-glucopyranoside]. Dhurrin was found in seedlings of each of the 10 entries of indiangrass [Sorghastrum mutans (L) Nash] and the three entries of S. pellitum.
Seedlings of five indiangrass cultivars were assayed for dhurrin concentration. Levels expressed as HCN potential (HCN-p) ranged from about 900 ppm for 'Holt' to about 1,200 ppm for 'Llano' and 'Oto'.
Further studies with Oto seedlings indicated that …


Sublethal Stress In Escherichia-Coli - Function Of Salinity, I. C. Anderson, Mw Rhodes, H Kator Dec 1979

Sublethal Stress In Escherichia-Coli - Function Of Salinity, I. C. Anderson, Mw Rhodes, H Kator

VIMS Articles

Sublethal stress in Escherichia coli was detected in various test media after exposure (in vitro) to seawater of various salinities. Stress was measured with an electrochemical detection technique and a,-galactosidase assay. Test media included EC medium, medium A-1, and tryptic soy broth modified to contain lactose for /?-galactosidase assay experiments. Stress was defined as the difference between a predicted electrochemical response time calculated for unstarved cells from a standard curve and the observed electrochemical response time for cells starved in seawater. The higher the salinity, the greater the stress for all test media examined. Stress was most pronounced in EC …
