Annotated Checklist Of Bats From South Dakota, J. Knox Jones Jr., Hugh H. Genoways
Annotated Checklist Of Bats From South Dakota, J. Knox Jones Jr., Hugh H. Genoways
University of Nebraska State Museum: Mammalogy Papers
Excepting the generalized accounts of Over and Churchill (1945), no attempt has been made previously to summarize the distribution of bats in South Dakota. In 1960, 1961, and again in 1965, field parties from the Museum of Natural History of The University of Kansas collected mammals in that state. Bats obtained by these parties, together with those on deposit in other institutions and the few specimens earlier reported from South Dakota by other workers (see cited literature), form the basis of the present report. Eleven species are here treated; two of these are represented in the state by two subspecies. …
Effects Of Hypothermia And Saline Injection Of Cesium-137 And Sodium-22 Metabolism In White Rats, Glenn Michael Dempsey
Effects Of Hypothermia And Saline Injection Of Cesium-137 And Sodium-22 Metabolism In White Rats, Glenn Michael Dempsey
Biology ETDs
The excretion rates and distribution of cesium-137 and sodium-22 were studied in white rats exposed to cold or over-hydration, or both.
A single intraperitoneal injection of cesium-137 or sodium-22 was administered to rats housed in metabolic cages. Rate of isotope excretion was determined by daily measurements of urine, feces, and the whole animal with a gamma scintillation spectrometer.
In one study rats were injected intraperitoneally with saline solution equivalent to 10% of the body weight one hour after having been injected with cesium-137. After 23 hours the rats were sacrificed and individual tissue counts were taken to be compared with …

Art In Psychotherapy, Robert R. Schopbach
Art In Psychotherapy, Robert R. Schopbach
Henry Ford Hospital Medical Journal
Art is a tool too often neglected in psychotherapy. A careful study of a patient's drawings will provide information concerning diagnosis, dynamics, and progress. If, in addition, the patient explains and elaborates upon the content and symbolism, the drawings become excellent psychotherapeutic devices providing an entry into the patient's unconscious.
Migration Of The Army Cutworm, Chorizagrotis Auxiliaris (Lepidoptera: Noctuidae). I. Evidence For A Migration, Kenneth P. Pruess
Migration Of The Army Cutworm, Chorizagrotis Auxiliaris (Lepidoptera: Noctuidae). I. Evidence For A Migration, Kenneth P. Pruess
Department of Entomology: Faculty Publications
Indirect evidence is presented to support the conclusion that the army cutworm, Chorizagrotis auxiliaris (Grote), migrates from the Great Plains to the Rocky Mountains during the spring and the same individuals return to the Plains in the fall. Spring activity occurs progressively later from east to west, the delay being greater than that caused by emergence but commensurate with flight potential of the moth. Flight is predominately from east to west and a constant turnover of moths occurs at all locations on the Plains. Seasonal occurrence in the mountains coincides with the period of inactivity on the Plains, during which …

Geographic Variation In The Ord's Kangaroo Rat In The Upper Rio Grande Valley, Keith B. Grisham
Geographic Variation In The Ord's Kangaroo Rat In The Upper Rio Grande Valley, Keith B. Grisham
Biology ETDs
The Ord's Kangaroo Rat has the most extensive geographic range of any Dipodonmys species, extending from southern Canada to within 20 degrees north of the equator on the Mexican Plateau. Testifying to intraspecific variation throughout this range, the most recent revision of subspecies (Setzer, 1949) liststhirty-five subspecies of Dipodomys ordii. This kangaroo rat is found throughout the Rio Grande Valley in suitable habitat and extends as far north as Saguache in the San Luis Valley of Colorado. I am interested in the geographic variation found in the upper Rio Grande Valley, here defined as that portion of the valley from …
A Microbiological Evaluation Of A Laminar Down-Flow Hood, Robert Henry Staat
A Microbiological Evaluation Of A Laminar Down-Flow Hood, Robert Henry Staat
Biology ETDs
An Envirco Model DF-400 laminar down flow hood with an exhaust HEPA filter adaptation was tested for its efficiency by using Bacillus subtilis var. niger as an indicator organism. The experimental emphasis was on the bacterial spore penetration of the frontal barrier and of the exhaust system. Interior and exterior challenges were made. The interior challenge utilized two heights and progressed from the front of the hood to the rear. Bacterial migration on the hood surface, surface impingement, ambient air conditions, and exhaust air were checked. All ambient air sampling was done with Andersen samplers. The exterior challenge consisted of …
Studies On The Effect Of Aeration On Spore Germination, Mary Jane Wilson
Studies On The Effect Of Aeration On Spore Germination, Mary Jane Wilson
Biology ETDs
Bacterial spores are refractile bodies formed within vegetative cells, generally of the genera Bacillus and Clostridium. Spores have also been reported in certain cocci, spirilla, and Azotobacter, although their kinship to spores of Bocillus and Clostridium is not well understood (Robinow, 1960). The spore is characterized by its refractility, impermeability to basic dyes, and increased resistance to heat, chemicals, radiation (Vinter, 1961), enzymes, and freezing (Murrell, 1961b). The spore is also well defined by its mode of formation, its peculiar structure, and its unique chemical composition.
The possibility that biological contamination in the form of spores might seriously confuse the …
The Effects Of Coelomic Fluid And Isotonic Homogenates Of The Freshwater Bryozoan Lophopodella Carteri On Fish Tissue, Roger H. Meacham
The Effects Of Coelomic Fluid And Isotonic Homogenates Of The Freshwater Bryozoan Lophopodella Carteri On Fish Tissue, Roger H. Meacham
Master's Theses
A study was made to determine if fish tissue was poisoned by the coelomic fluid extracted from the common coelomic cavity of colonies of the freshwater bryozoan, Lophopodella carteri (Hyatt). Additional studies were made of fish tissues, in vivo and in vitro, when exposed to homogenates of crushed colonies of L. carteri in isotonic medium.
The fish exposed to the coelomic fluid did not show any signs of respiratory distress and therefore the poisonous quality must be located elsewhere in the bryozoan. The homogenates were determined to be poisonous as fishes exposed to a 3.0% solution were killed within an …

A Comparative Study Of The Sulfhydryl Groups In The Gastrocnemius Of The Normal And X-Irradiated Pet Mouse, Robert Edward Shervette
Master's Theses
It has been recognized that hyperpigmentation of the skin is the result of eliminating the. -SH inhibition when treatment is by x-irraidiation. The results of a. study by fieams and Schaeffer indicate : a progressive increase of melanocytes in the skin with an increasing dosage of x-irradiation. However, it was also noted that the effect of x-irradiatin on the gastrocnemius of the PET mouse resulted in a decrease in the number of intramuscular melanocytes. The present study was designed to determine whether the changes in the x-irradiated muscle is related to possible changes in -SH concentration.The technique employed is a …
The Ultrastructure Of The Vibratory Muscle Of Crotalus Horridus, Louis Pastore
The Ultrastructure Of The Vibratory Muscle Of Crotalus Horridus, Louis Pastore
Master's Theses
A comparison of the vibratory and epaxial muscles of Crotalus horridus horridus Linnaeus wa smade. muscle fibers, fibrils, filaments, mitochondria and sarcoplasmic reticulum were described in this study. The sarcomeres of the epaxial muscle were almost three times the length of those of the vibratory muscle. The A band was observed to be about twice the length of the I band in the vibratory muscle. As seen in cross section the vibratory muscle had fibrils arranged in discrete packets with a limited number of thick myofilaments. In contrast, the fibrils of epaxial muscle were less conspicuously separated from each other …

Hematological Variation Associated With Altitude, Season, Sexual Activity And Body In The Uinta Ground Squirrel, Ralph Theodore Kinchloe
Theses and Dissertations
Hematological comparisons were made on the Uinta ground squirrel (Citellus armatus) trapped at different altitudes and during vari ou s stages of seasonal activity in 1965 and 1966. Hematological variation due to sex, sexual activity and body weight were also analyzed. Ground squirrels were secured from the Mt. Timpanogos area near Provo, Utah County, Utah. Erythrocyte count, hematocrit, total blood hemoglobin, mean erythrocyte volume, mean erythrocyte hemoglobin and reticulocyte counts were measured using standard procedures; banding patterns of hemoglobin and serum proteins wer e determined by means of electrophoresis with polyacetate strips.
An Electrophoretic And Chromatographic Study Of The Hemoglobin From Adult And Fetal Pigs, Donald William Green
An Electrophoretic And Chromatographic Study Of The Hemoglobin From Adult And Fetal Pigs, Donald William Green
Theses and Dissertations
Hemoglobin, from the erythrocytes of adult and fetal pigs, was isolated and analyzed by carboxymethylcellulose column chromatography and electrophoresis on polyacetate. These techniques demonstrate the existence of four fetal components (F0, F1A, F1B, F1C) and two adult components (A0, A1) based on their elution pH values and electrophoretic mobilities. The shift from-fetal to adult forms is initiated sometime between eight weeks after birth and one year. The change is not completed until sometime after one year and the major fetal forms (F0, F1A) maintain a 15% level in a mature adult. This report is in contrast with the results of …

An Ecological Study Of The Algae And Mosses Of Cascade Springs, Wasatch County, Utah, Deanna Lynn Mccoard
An Ecological Study Of The Algae And Mosses Of Cascade Springs, Wasatch County, Utah, Deanna Lynn Mccoard
Theses and Dissertations
An ecological study was conducted at Cascade Springs, Wasatch county, Utah from August 1965, to June 1967. The algae and aquatic moss species were determined and ecological information about these organisms was obtained. Physical data were also collected: bicarbonates, carbonates, free carbon dioxide, hydroxides, oxygen, pH, and temperature. The physical environment of the water was found to be very constant. Tests taken at the different study sites were consistently similar, not only during each day, but all year around. No great variation of any kind was found in the water. In contrast to the water environment, the topography of the …
Predation Of Leptothrips Mali (Fitch) On Mites In Central Utah Orchards, James G. Brooks
Predation Of Leptothrips Mali (Fitch) On Mites In Central Utah Orchards, James G. Brooks
Theses and Dissertations
Predation by thrips was referred to as early as 1882 when Pergande discussed their habits. Later, Plank (1936) found Leptothrips mali (Fitch) to be predaceous on lepidopterous eggs, and Sharp (1938) cited it as a being a predator of the pecan nut caseborer, Acrobasis caryae Grote. Bailey (1939) stated that the six-spotted thrip, Scolothrips sexmaculatus (Pergande), is predaceous on Tetranychus telarius (L.), Tetranychus pacificus McG., Bryobia praetiosa Koch, Paratetranychus citri McG., Paratetranychus pilosus (C & F.), Paratetranychus indicus Hirst, Paratetranychus yothersi (McG.), Paratetranychus ilicis (McG.), and Phyllocoptes oleivorus Aschm. and in 1943 Bailey and Keifer noted that L. mali fed …

Development And Vasculature Of The Flowers Of Lophotocarpus Calycinus And Sagittaria Latifolia (Alismaceae), Robert B. Kaul
School of Biological Sciences: Faculty Publications
The development of the bisexual flower of Lophotocarpus calycinus and of the unisexual flowers of Sagittaria latifolia has been observed. In all cases floral organs arise in acropetal succession. In L. calycinus, after initiation of the perianth, the first whorl of stamens to form consists of six stamens and is ordinarily followed by two alternating whorls of six stamens each. The very numerous carpels are initiated spirally. In the male flower of S. latifolia the androecium develops in spiral order. A few rudimentary carpels appear near the floral apex after initiation of the stamens. There are no staminodia. The female …
