The Functional Morphology And Ecology Of Chone Mollis, Dale Brian Bonar

University of the Pacific Theses and Dissertations

Chone mollis occurs in large numbers in Tomales Bay and is an ecologically important infaunal member of the bay community. As with most marine communities, very little work has been done with individual species of the community. The present study of C. mollis is a contribution towards an understanding of the community as an ecological unit.

This study investigates the structure and function of the tube; tube-building habits; burrowing and locomotion; external anatomy; feeding; and internal anatomy of the muscular, skeletal, vascular, excretory, reproductive, and alimentary systems of C. mollis.

A Myological And Osteological Comparison Of The Pelvic Appendage Of The Male And Female Western Meadowlark, Thomas Felix Sourisseau Jr.

University of the Pacific Theses and Dissertations

Sexual dimorphism has been noted to exist in many genera of birds, but it is not until recently that papers have appeared which deal with the actual extent of sexual dimorphism and its possible adaptive significance. The papers of Rand (1952), Sibley (1957), Amadon (1959), and Selander (1966) hypothesize about the possible significance of sexual dimorphism in birds, and the papers of Kilham (1965), Selander (1965), Storer (1966), Ligon(1968), Ingolfsson (1969), and Verner and Willson (1969) examine the relationship between hypotheses on the significance of sexual dimorphism and actual field conditions. None of these papers deals with differences in bone …

Studies On An Antibiotic-Producing Strain Of Bacillus Megaterium X, Kishori Madhukar Chaubal

University of the Pacific Theses and Dissertations

On July 10, 1968, while observing the effects of ultra-violet light on a plate culture of Sarcino lutea, o contaminant was found growing in the form of a colony surrounded by a clear zone of inhibition where S. lutea had failed to grow. A smear from this contaminant colony was found to contain a Gram positive, chain-ond spore-forming bacillus. The organism was isolated and its antagonism against S. lutea was reshocked. Preliminary investigation of its activity against other bacteria indicated that this activity was directed against 5. lutea only. I was decided to continue the investigations with two aims in …

Biological Studies Of Bimeria Franciscana (Hydrozoa: Gymnoblastea) From The Petaluma River, California, Jose Rigoberto Gomez

University of the Pacific Theses and Dissertations

The athecate hydroid Bimeria franciscana Torrey has been found in estuarine habitats throughout the world. For this study B. franciscana was collected along the docks of the Petaluma River, California, a new collection site. Investigations on the appearance and biology of this hydroid have not been recorded in this area, perhaps because of its relative rarity along the river

Distribution records and synonymy of B. franciscana as well as general taxonomic characteristics of the species of the Genus Bimeria present on the west coast of the United States are assembled in a series of appendices added to this work. This …

Evaluation Of The Essentiality Of Dextran In The Dental Caries Process, William Redman Grigsby

Theses and Dissertations

In summary, the main points to support the view that dextran synthesis is unessential to the dental caries process are presented below:

1 . Dextran-fed, microbe-bearing rats do not experience dental caries.

2 . Lactobacillus casei 4646 has no extracellular dextransucrase enzyme or other extracellular enzymes which release glucose or fructose from sucrose .

3. L. casei 4646 does not synthesize extracellular polysaccharide of the dextran class when grown on sucrose-containing medium.

4. L. casei 4646 does not exhibit in vitro, adherent growth on stainless-steel wire when grown on sucrose-containing medium .

5. L. casei 4646 does not cause dental …

The Development Of Behavior And The Ossification Of Bone In The Bantam-Chick Embryo, Christine M. Hagedorn

Dissertations and Theses @ UNI

The objectives of this study were (1) to establish an index of standard behavior, and (2) to establish an index of skeletal development for each day of embryonic development for the bantam-chick embryo. The principal method used was direct observation of the embryo. This was done by removing the shell from the blunt end of the egg and applying a coating of vaseline to the exposed inner-shell membrane. The bones observed in skeletal development were made visible by alizarin red S stain. Behavioral activities of the bantam-chick embryo included trunk movements, head lifting, head turning, wing movements, leg movements, jerking, …

Cation Transport I. Metabolic Activity Of The Polyphosphoinositide Complex In Isolated Renal Cortex Tubules, Paul Bartlett, James F. Bossart

Henry Ford Hospital Medical Journal

Although several mechanisms have been proposed to explain the transport of hydrophylilc cations across lipoprotein barriers, the nature and identity of the carrier mechanism have not yet been elucidated. The present communication is concerned with a mechanism postulating that monoesterified phosphate on the inositol moiety of phosphatidyl inositol might provide anionic sites that function as cation carriers via a phosphorylation-dephosphorylation cycle, catalyzed in its simplest sequence by phosphatidyl inositol kinase and diphosphoinositide phosphomonoesterase activities. In this context, one might reasonably expect that turnover of monoesterified phosphate in the polyphosphoinositides of isolated renal cortex tubules would be reduced in tubules in …

Protein Synthesis During Fungal Spore Germination. Iv. Transfer Ribonucleic Acid From Germinated And Ungerminated Spores, James L. Van Etten, R. Kent Koski, Mahmoud El-Olemy

Department of Plant Pathology: Faculty Publications

Transfer ribonucleic acid (tRNA) fractions isolated from germinated and ungerminated spores of Botryodiplodia theobromae and Rhizopus stolonifer had acceptor activity for all 20 amino acids commonly found in protein, when tested with an enzyme fraction from germinated spores. Accordingly, it is unlikely that the absence of tRNA for a particular amino acid limits protein synthesis in fungal spores.

Hatching Of Sod Webworm Eggs In Relation To Low Temperatures, E. A. Heinrichs, Ellis L. Matheny

Department of Entomology: Faculty Publications

Eggs of Chrysoteuchia topiaria (Zeller), Crambus pascuellus floridus (Zeller), and Pediasia trisecta (Walker) were exposed to temperatures of 25, 15, 10, 4, and –10°C. Only those of P. trisecta hatched after exposure to 4°C for 30 days, while none hatched after exposure to –10°C. Eggs of none of the species hatched after exposure to 4 and 10°C for 60 days. Pre-exposure and post-exposure conditioning had no significant effect on percent hatch of P. trisecta eggs, while length of exposure period had a significant effect.

Lipid Content And Seasonal Activity Of Odontopus Calceatus (Coleoptera: Curculionidae) Adults, E. A. Heinrichs

Department of Entomology: Faculty Publications

Overwintering Odontopus calceatus (Say) adults were first observed feeding on April 10. Weekly collections during the activity period indicated that new-generation adults began emerging June 4. By July 23 they had entered the forest litter for hibernation. Lipid content decreased throughout the hibernation period as the weevils utilized 77% of their total lipid content during this time. The most rapid decrease during hibernation occurred from February to March, just prior to mating and oviposition in the spring. No increase in lipid content occurred during the activity period in spring and summer. A great increase in lipid content did occur within …

Sweetclover Weevil Feeding Stimulants: Isolation And Identification Of Glucose, Fructose, And Sucrose, W. R. Akeson, H. J. Gorz, Francis A. Haskins

Department of Agronomy and Horticulture: Faculty Publications

The water-soluble fraction of Melilotus leaves previously referred to as Stimulant A was further fractionated by preparative paper chromatography into three factors, each having a stimulatory effect on sweetclover weevil feeding. The three factors, designated Stimulant A₁, A₂, and A₃, were identified as sucrose, glucose, and fructose, respectively, by co-chromatography with known sugars on cellulose-coated thin-layer plates. Silver nitrate, anisidine phthalate, and anthrone were employed as detection agents. The isolated compounds and corresponding reagent grade sugars were identical in chromatographic and chemical behavior, as well as in feeding stimulant activity. Sucrose stimulated the greatest …

Parasitic Organisms In The Blood Of Arvicoline Rodents In Alaska, Francis H. Fay, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

A Grahamella-like organism (Schizomycetes: Bartonellaceae) was found in erythrocytes of laboratory-reared northern voles, Microtus oeconomus Pallas, which had been inoculated intraperitoneally with a saline suspension of ground fleas, Megabothris abantis (Roths.), from wild northern voles captured at Lower Ugashik Lake, Alaska Peninsula. A live-trapped northern vole from the same locality harbored trypanosomes referable to T. microti (Mastigasida: Trypanosomatidae). Two morphologically similar but biologically different strains of piroplasms (Piroplasmasida: Theileriidae) of uncertain generic status were isolated from northern voles of Ugashik Lake origin and from northern red-backed voles, Clethrionomys rutilus Pallas, from the vicinity of Anchorage, Alaska. In the natural …

Quasilattice Interpretation Of The Thermodynamic Properties Of Mixing Of Binary Alkali-Metal Systems, J. Bevan Ott, J. Rex Goates

Faculty Publications

Quasilattice theory was applied to heats of mixing in the six systems formed from the binary combinations of Na, K, Rb, and Cs. The alkali-metal systems are particularly well suited for a critical test of the quasi-crystalline assumption since the theoretical model for these systems is relatively simple and the thermodynamic data are fairly complex. Very good fits of the heat-of-mixing data were achieved by assuming that the larger atom in the binary system covered multiple sites on the quasilattice. The values of the empirically determined constants appear to fit the physical significance accorded to them by the quasilattice model. …
