Geographic Variation In Myotis Californicus In The Southwestern United States And Mexico, Michael Allen Bogan

Biology ETDs

A total of 487 adult Myotis californicus from the southwestern United States and Mexico were examined and analyzed utilizing both univariate and multivariate procedures. The major conclusions are as follows:

1. Females average larger in most characters studied, but the pattern of variation is discontinuous with different samples sexually dimorphic to different extents and in different characters. The possibility of niche partitioning is discussed.
2. Individual variation in this species appears low as shown by coefficients of variation.
3. Univariate analysis indicates a slight increase in size of most characters studied from west to east. This size increase is gradual with considerable overlap …

Experimentation To Develop Procedures To Be Used In The Investigation Of The Effects Of Restriction On The Unmodified Dna Of The Bacteriophage Lamda, John Haynes

Honors Theses

The results of experimentation approximately twenty years ago with variuos bacteriophages by Ralston and Krueger¹⁶, Anderson and Felix¹, Luria and Human¹², and by Bertani and Weigle² have shown that the host range of a given phage depends directly on the bacterial strain on which the phage has last propagated. This event came to be known as host-induced modification or host-controlled variation. As this phage host range is controlled by the host environment and can be altered from one generation to another it has, according to Luria, made microbiology "the last stronghold of Lamarckism" …

Purification And Characterization Of Dihydroorotase From Clostridium Oroticum, A Zinc-Containing Metalloenzyme, William Edward Balch

Dissertations and Theses

Dihydroorotase (4,5-L-dihydro-orotate amidohydrolase, EC 3.5.2.3) which catalyzes the reversible cyclization of N-carbamyl-1-aspartate toL-dihydro-orotate has been purified from orotate-grown Clostridium oroticum by a combination of streptomycin sulfate fractionation, DEAE-Sephadex chromatography, and hydroxylapatite chromatograpy. The enzyme has been shown to be omogeneous when subjected to polyacrylamide gel electrophoresis. Thin-layer gel chromatography with Sephadex G-200 indicated the enzyme to have a molecular weight of 110,000 ± 10,000. Sodium dodecyl sulfate gel electrophoresis using two different buffer systems indicate the enzyme to be composed of two identical subunits with a molecular weight of 56,000 ± 5300. Dihydroorotase has been shown to be a zinc-containing …

The Peregrine Falcon In Utah, Emphasizing Ecology And Competition With The Prairie Falcon, Richard D. Porter, Clayton M. White

Brigham Young University Science Bulletin, Biological Series

This study was undertaken to record the known history of the Peregrine Falcon (Falco peregrinus) in Utah as we have been able to construct it from both the literature and from our original research that extends over about a 30-year period in the state. The present total population of the peregrine in Utah is possibly only 10 percent of what it has been in historic times. In an effort to find explanations for the decline, we have explored hypotheses of climatic changes, impact of pesticides, disease, and human disturbances. We conclude that pesticide contamination and climatic changes may …

Breeding Ecology Of Raptors In The Eastern Great Basin Of Utah, Dwight G. Smith, Joseph R. Murphy

Brigham Young University Science Bulletin, Biological Series

A comparative study of the breeding ecology of 12 raptor species was conducted in the eastern Great Basin from 1967-1970. The project was designed to determine the composition and densities, habitat selection, territoriality and predatory habits of raptorial birds in a semiarid environment. All topics were analyzed comparatively, relating the requirements and activities of the 12 raptor species.

Average yearly population densities of all species approximated 0.5 pairs per square mile, but much of the available habitat was not utilized. Predominant raptors were the Ferruginous Hawk and Great Horned Owl. Other important raptors included the Golden Eagle, Red-tailed Hawk and …

Osmoregulatory Adaptations Of The Spiny Softshell Turtle, Trionyx Spiniferus, From Brackish And Fresh Waters, Michael E. Seidel

Biology ETDs

Two geographically separated populations of the Texas spiny softshell turtle, Trionyx spiniferus emoryi, were collected in New Mexico and their osmoregulation and body fluid compositions were studied. One population inhabits fresh water (0.09% saline) and the other inhabits brackish water (0.79% saline). Turtles were maintained in laboratory water analogous to their field environments and then acclimated to tap water or 0.7% saline. Weight changes and urine flow were measured. Blood and urine samples were obtained from turtles in each aqueous environment and analyzed for sodium, potassium, calcium, magnesium, urea, and protein. Osmotic pressure of these samples was also measured.

Papers in Behavior in Biological Sciences

Laboratory-raised Northern blue jays (Cyanocitta cristata) have been observed tearing pieces from pages of newspaper and utilizing them as tools to rake in food pellets which were otherwise out of reach. The frequency of this behavior was dependent upon the motivational state of the jay and the presence of food pellets.

Cathetocephalus Thatcheri Gen. Et Sp. N. (Tetraphyllidea: Cathetocephalidae) Fam. N. From The Bull Shark, Murray D. Dailey, Robin M. Overstreet

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Cathetocephalus thatcheri gen. et sp. n. is described from the spiral valve of the bull shark, Carcharhinus leucas (Valenciennes), taken in the Gulf of Mexico and the Atlantic coast of Florida. A new family is erected for the new genus. The species most closely resembles Pillersium owenium Southwell, 1927, in that both possess a scolex which is perpendicular to the long axis of the strobila. It differs, however, in having a single neck and holdfast organ rather than a bifurcate neck with two bothridia. Also, the surfaces of the scolex differ from those of P. owenium by possessing fleshy papilliform …

Effects Of Hypothyroidism In Mice Infected With Schistosoma Japonicum Katsurada, 1904, Venus Ee-Siriporn

Loma Linda University Electronic Theses, Dissertations & Projects

Section I:

In order to determine the effects of propylthiouracil-induced hypothyroidism on the Formosan strain of Schistosoma japonicum in mice, one group of mice (NON-PTU) was maintained on Purina Lab Chow meal only; the other group of mice (PTU) was fed a goiterogenic diet of 0.2% propylthiouracil in Purina Lab Chow meal. The mice in both groups were percutaneously exposed to 60 to 72 cercariae. The mice were perfused for schistosomes after an infection period of two months. It was found that the number of worms recovered was not significantly different between the two groups of mice. PTU mice weighed …

Role Of Membrane-Associated Components Of Mycoplasma Arthritidis On The Biosynthesis Of Humoral Antibodies And Arthritogenic Properties In Experimental Animals, Lois M. Bergquist

Loma Linda University Electronic Theses, Dissertations & Projects

The virulence of animal-passaged Mycoplasma arthritidis (158) was demonstrated to be enhanced in rats by growth in oleic acid-enriched broth. The virulence of a laboratory-maintained culture of the same strain was unaffected by similar growth conditions. No differences either in the immune response as measured by complement-fixing (CF) antibodies or in the histogenesis of the disease were detected when rats were injected with animal-passaged M. arthritidis grown either in the presence or in the absence of oleic acid. All tests for metabolism-inhibiting (MI) antibodies in the rat were negative.

A Mycoplasma-associated immunosuppression of the primary and of the secondary hemagglutinin …

Life Cycle Of Euparyphium Neomexicanum Sp. N. (Trematoda, Echinostomatidae), Gary L. Strong

Biology ETDs

The life cycle of Euparyphium neomexicanum sp. n. (Trematoda, Echinostomatidae) from New Mexico ditches, ponds, and streams was studied. The 45-spined adult, measuring 1.4 to 2.6 by 0.37 to 0.57 mm, was raised to maturity in 11 days in laboratory rats and mice. Eggs 84 to 113 by 57 to 78 µm, could not be hatched, and the miracidium was not observed. At least two redial stages are present in Physa virgata Gould. Cercariae exit the mother snail, then swim and encyst in the mother snail, in another Physa of the same species, or in Heliosoma tenue Philippi. The natural …

Intra- And Interspecific Aggression In House Finches And House Sparrows, Ronald L. Kalinoski

Biology ETDs

Aggression in House Finches and House Sparrows was studied at an outdoor feeder in winter and in indoor cages. In the wild, frequencies of encounters conformed to patterns of daily and seasonal feeding activity. House Sparrows of both sexes were dominant to House Finches, especially in cages. House Finches were more aggressive intra- than interspecifically. House Sparrows showed equal proportions of aggression toward finches and each other. House Finches maintained stable peck-right dominance hierarchies. House Sparrows exhibited extreme lability in dominance relationships, with no emergent structure. Interspecific aggression in these species was related to violations of individual distance at common …

Mercury Levels In Lake Powell, Arizona-Utah, Donald R. Standiford

Biology ETDs

Flameless atomic absorption analysis of samples from Lake Powell yielded mercury in mean parts per billion of 0.01 in lake water, 30 in bottom sediments, 10 in shoreline substrate, 34 in plant leaves, 145 in plant debris, 28 in algae, 10 in crayfish, and 232 in fish muscle. Concentrations are expressed on a wet-weight basis for animals, all other samples are on a dry-weight basis. In bottom sediments mercury levels were higher in sediments with higher organic content and finer texture. The mercury content of plant leaves was higher than that of stems and roots. Lake­transported plant debris had higher …

(+) -Abscisic Acid: Identification, Measurement And Biosynthesis In Roots Of Phaseolus Vulgaris L., Mary L. Barr

Biology ETDs

Roots of Phaseolus vulgaris L. (var. Red Kidney) have been shown to play a significant role in contributing to the level of the plant hormone (+) -abscisic acid ((+) -ABA) in the growing plant. Furthermore, an environmental factor, water deficit has been shown to have a direct effect on the biosynthesis of (+) -ABA in roots. Presumed (+) -ABA from roots of red kidney bean was identified as (+) -ABA by its physical properties including optical rotatory dispersion (ORD), ultraviolet absorption, and chromatographic behavior and by its biological activity as observed in the lettuce seed germination bioassay and wheat coleoptile …

The Flora Of Mount Sedgwick And Vicinity, Nancy L. Riffle

Biology ETDs

The purpose of this study was to determine the composition of the flora around Mount Sedgwick in the Zuni Mountains, Valencia County, New Mexico. More than 1100 specimens were collected during the spring and summer of 1968 and 1969. These specimens were identified to species or lower taxa, and a total of 353 species in 61 families were represented. The limitations of altitude, and the presence of permanent moisture largely determined the composition of the flora in the various study areas. Habitats studied included a steep dry canyon, ponderosa pine forest, two springs and meadows, a permanent pond and stream, …
