The Genus Haemolaelaps (Acarina: Laelapidae) In The Northwest Ethiopian Biogeographical Region, Calvin J. Sakamoto May 1977

The Genus Haemolaelaps (Acarina: Laelapidae) In The Northwest Ethiopian Biogeographical Region, Calvin J. Sakamoto

Theses and Dissertations

This paper presents the results of a taxonomic stury of mites of the genus Haemolaelaps collected from small mammals of 8 political subdivisions of the northwest portion of the Ethiopian Biogeographical Region. Specimens taken from 2,863 small mammals from a wide variety of habitats and localities were examined. The Haemolaelaps fauna includes 23 species, 10 of which are described as new: H. bellasoma, H. caurinus, H. chaetospinicus, H. crocidura, H. desmodilliscus, He. ebsi, H. malachela, H. parahirsti, H. sikapusi and H. taterakempi. Numerical taxonomic and multicariate analyses were used to assess variation and clustering. A key for identification of females …

Accumulation And Metabolism Of Triphenyltin Hydroxide (Du-Ter) In Channel Catfish, Hal B. Jenson Apr 1977

Accumulation And Metabolism Of Triphenyltin Hydroxide (Du-Ter) In Channel Catfish, Hal B. Jenson

Theses and Dissertations

The fate of ring-14C labeled triphenyltin hydroxide was studied in a model ecosystem consisting of soiI, water, and channel catfish (Ictalurus punctatus). Two initial levels of triphenyltin hydroxide concentration in soiI, 1.0 and 0.010 ppm, were compared. The soiI showed a gradual loss of 20 to 30% of the total 14C residues. Only about 33% of the remaining soil residues could be extracted and almost all of these were triphenyltin hydroxide. Total residues in the water were very low. Catfish muscle and viscera accumulated 14C residues continually throughout the treatment portion of the experiment. When the catfish were transferred to …

Isolation, Purification, Scanning Electron Microscopy And Bacterial Dna Uptake Of Plant Protoplasts, Bronwyn G. Hughes Apr 1977

Isolation, Purification, Scanning Electron Microscopy And Bacterial Dna Uptake Of Plant Protoplasts, Bronwyn G. Hughes

Theses and Dissertations

Protoplasts were isolated from tobacco and barley leaves in sucrose or mannitol using commercially available cellulases and macerozymes. Barley growth and protoplast isolation and purification conditions were optimized so that protoplasts were obtained in high yields free of unwanted debris and organelles. A technique for processing barley and tobacco protoplasts for examination by scanning electron microscopy was developed in which protoplasts seem to have maintained their structural integrity. Barley and tobacco protoplasts took up 3H-B. subtilis DNA, 125I-B. subtilis DNA or 125I-M. luteus DNA as a linear function of time (0-6 hr) and DNA concentration (0-200 μg/ml). Up to 16 …

Partitioning Of Space And Time By The Western Jumping Mouse, Zapus Princeps Utahensis Hall, John M. Deacon Apr 1977

Partitioning Of Space And Time By The Western Jumping Mouse, Zapus Princeps Utahensis Hall, John M. Deacon

Theses and Dissertations

Intraspecific competition is important in determining habitat utilization by members of a single species. Effective use of habitat may involve partitioning the available resources: space, time and food among individuals of different age, sex, and/or reproductive state. Numerous publications deal with interspecific competition (McCloskey and Fieldwick 1975, Cody 1973, Rosenzweig 1973, Stewart and Levin 1973, Gaby 1972, Brown 1971, Koshkina 1971, Sheppe 1967, Caldwell and Gentry 1965, Cameron 1964, Clough 1964, Gause 1932), but little has been written on intraspecific competition among populations of organisms in nature.

Cattail Decline At Farmington Bay Waterfowl Management Area, Christine Minton Anderson Mar 1977

Cattail Decline At Farmington Bay Waterfowl Management Area, Christine Minton Anderson

Great Basin Naturalist

For the last seven years, 1969 to 1976, a steady decline of cattails (Typha latifolia L.) has been observed at Farmington Bay Waterfowl Management Area, Davis County, Utah. Several parameters of Farmington Bay's environment that could cause or enhance a decline of the marshland vegetation were studied. These parameters included temperature, pH, phenols, oil and grease, heavy metals, fungus pathogens, and salt water intrusion from the Great Salt Lake. Elevated soluble salt concentrations were found to be responsible for the decline. Cattails are weakened or killed when they are exposed to soluble salt concentrations greater than 5.0 gm/liter, and …

Interpopulational Variation Of Blood Proteins In Pika (Ochotona Princeps Saxatilis), John T. Brunson, Richard N. Seaman, Donald J. Nash Mar 1977

Interpopulational Variation Of Blood Proteins In Pika (Ochotona Princeps Saxatilis), John T. Brunson, Richard N. Seaman, Donald J. Nash

Great Basin Naturalist

Studies were undertaken to examine the degree of divergence in four populations of pika in Colorado. Separation of blood proteins was accomplished utilizing acrylamide-gel disc electrophoresis. Separate analyses of variance were carried out for the relative mobilities of two of the transferrins (designated RMβ1 and RMβ2), the mean relative distance difference of the two transferrins (DM), and the density of the most prominent albumin (α1) and transferrin (β2) bands. Although the four populations were characterized by a general similarity of the gel patterns, both interpopulational and sexual variations were observed. …

Preliminary Mammal Survey Of Fossil Butte National Monument, Wyoming, Tim W. Clark Mar 1977

Preliminary Mammal Survey Of Fossil Butte National Monument, Wyoming, Tim W. Clark

Great Basin Naturalist

The mammalian community of Fossil Butte National Monument, Wyoming, consisted of at least 45 species. Snap trap sampling of the smaller species combined with sight and sign observations of the larger species formed the basis of this preliminary survey in the summers of 1974 and 1975. Snap-trapping samples (2880 trap days) yielded 44 least chipmunks and 89 deer mice. The distribution of all species was characterized by plant community occupancy. Heavy domestic livestock use of the communities nearest water has resulted in severe alteration in community structure; this has probably affected the distribution and abundance of at least some of …

Home Range Of The Western Jumping Mouse, Zapus Princeps, In The Colorado Rocky Mountains, Nathaniel Stinson Jr. Mar 1977

Home Range Of The Western Jumping Mouse, Zapus Princeps, In The Colorado Rocky Mountains, Nathaniel Stinson Jr.

Great Basin Naturalist

Western jumping mice, Zapus princeps, were live-trapped during the summer of 1975 in an aspen forest in the Front Range of the Colorado Rocky Mountains. Home range sizes were calculated using the exclusive boundary strip method, and it was discovered that males had larger home ranges (298–3315 m2, x̄ = 1743 m2) than females (680–1275 m2, x̄ = 1041 m2). Mean range length was 96.5 m for males and 78.5 m for females. Spatial relationships showed that females tended to be more territorial than males, based on the females' higher percentage of …

Osteology And Myology Of The Head And Neck Regions Of Callisaurus, Cophosaurus, Holbrookia, And Uma (Reptilia: Iguanidae), Douglas C. Cox, Wilmer W. Tanner Mar 1977

Osteology And Myology Of The Head And Neck Regions Of Callisaurus, Cophosaurus, Holbrookia, And Uma (Reptilia: Iguanidae), Douglas C. Cox, Wilmer W. Tanner

Great Basin Naturalist

A detailed study of the anterior osteology and myology of Callisaurus, Cophosaurus, Holbrookia, and Uma reveals the phylogenetic relationships among the sand lizards. An SPSS discriminant analysis of osteological characters combined with myological characters indicates that Callisaurus is most primitive, Cophosaurus and Holbrookia are most closely related, and Uma is the most distinct of the sand lizard genera. Because of close relationships between Cophosaurus and Holbrookia, it is postulated that earlessness evolved once, and Cophosaurus is returned to synonymy under Holbrookia.

Cytosol Binding Of Steroid Hormones In Sheep Brains And Pituitaries, David Carl Marcusen Mar 1977

Cytosol Binding Of Steroid Hormones In Sheep Brains And Pituitaries, David Carl Marcusen

Theses and Dissertations

The uptake and binding of tritiated cortisol, corticosterone, and dexamethasone in cytosols isolated from various regions of non-adrenalectomized (intact) and adrenalectomized sheep brains and pituitaries were studied. [3H]-cortisol and [3H]-corticosterone were bound preferentially by cytosols from the hippocampal and septal regions of the brain, whereas, [3H]-dexamethasone was preferentially bound by cytosol from the pituitary. Cytosols isolated from the brains of adrenalectomized sheep bound significantly more [3H]-corticosterone than did cytosol from the brains of intact animals. Pre-incubation of cytosols from the hippocampus of adrenalectomized animals with non-radioactive testosterone or estradiol did not significantly block the subsequent binding of [3H]-cortisol. Results of …

Utilization Of Nest Boxes By Birds In Three Vegetational Communities With Special Reference To The American Kestrel (Falco Sparverius), Laurence Barrett Mcarthur Mar 1977

Utilization Of Nest Boxes By Birds In Three Vegetational Communities With Special Reference To The American Kestrel (Falco Sparverius), Laurence Barrett Mcarthur

Theses and Dissertations

This study was designed to determine if, by providing artificial nest sites, a raptorial predator could be attracted into an area where suitable sites are limited. The American Kestrel (Falco sparverius) was a common species in the area and nest boxes designed for their use were placed in three vegetational types in western Utah and eastern Nevada. Seventy boxes were available in 1975 and 110 in 1976. Kestrels nested both years in the salt-desert shrub community but were absent from the pinyon-juniper and riparian areas. Four other bird species nested in the latter two areas, however. In 1975 the nesting …

Certain Edaphic And Biotic Factors Affecting Vegetation In The Shadscale Community Of The Kaiparowits Area, Vane Orlan Campbell Mar 1977

Certain Edaphic And Biotic Factors Affecting Vegetation In The Shadscale Community Of The Kaiparowits Area, Vane Orlan Campbell

Theses and Dissertations

A study area on the southern extensions of the Great Basin cold desert (Kaiparowits Basin, Utah) was selected which has had varying amounts of disturbance. Areas with similar slope and exposure in the Shadscale community were sampled. At each site, soil samples were collected and percent sand, percent clay, percent silt, soluble salts, and hydrogen ion concentrations were measured. Cluster analysis based on percent frequency of the perennial species showed that eight groups or sub-communities were definable within the area sampled. Patterns within the vegetation were shown to be independent with the use of cluster analysis. Discriminant analysis on soil …

Late Pleistocene Vertebrates Of The Silver Creek Local Fauna From North Central Utah, Wade E. Miller Dec 1976

Late Pleistocene Vertebrates Of The Silver Creek Local Fauna From North Central Utah, Wade E. Miller

Great Basin Naturalist

Presumed paludal and alluvial deposits in a small mountain basin in north central Utah have yielded the first terrestrial Pleistocene fauna from the state. Twenty-five mammalian and four nonmammalian species are present, most of which have not previously been reported as fossils from Utah. At 6,400 feet the elevation of this site is much too high to have been part of the Lake Bonneville deposition. Three mammals, Ovis, Symbos, and Bootherium, not existing in the present fauna, have been identified in the northern part of the state. They probably did not reach this area until later in …

Flea Exchange Between Deer Mice And Some Associated Small Mammals In Western Utah, Harold J. Egoscue Dec 1976

Flea Exchange Between Deer Mice And Some Associated Small Mammals In Western Utah, Harold J. Egoscue

Great Basin Naturalist

Fleas obtained from deer mice and each of three sympatric rodents collected at the same times and places are quantified. When deer mice and canyon mice were caught together, 18.9 percent of the infested deer mice had canyon mouse fleas while 20.8 percent of infested canyon mice carried deer mouse fleas; long-tailed vole fleas were collected from only 3.9 percent of the deer mice but 67 percent of the voles associated with deer mice had fleas normally found on the latter; reciprocity was lowest between deer mice and desert wood rats, with three wood rat fleas found among 155 fleas …

Helminth Parasites Of Cats And Dogs From Central Utah, Thomas W. Sawyer, Lari M. Cowgill, Ferron L. Andersen Dec 1976

Helminth Parasites Of Cats And Dogs From Central Utah, Thomas W. Sawyer, Lari M. Cowgill, Ferron L. Andersen

Great Basin Naturalist

A survey of the helminth parasites of 100 stray cats and 50 dogs was conducted. Each host was euthanized, and the internal organs were excised and examined for parasites. Helminths identified from cats included the tapeworms Dipylidium caninum and Hydatigera taeniaformis, and the nematodes Physaloptera sp. and Toxocara mystax. Two species of coccidia, Isospora felis and I. rivolta, and one ectoparasitic mite, Cheyletiella parasitivorax, were also recovered from cats during sugar flotation of the feces. Helminths identified from dogs included the tapeworms D. caninum, Taenia hydatigena, T. krabbei, and T. pisiformis, and the nematodes Filaroides milksi, Toxascaris leonina, and Toxocara …

Effect Of Altitude On The Peripheral Degradation Of Thyroxine In The Uinta Ground Squirrel (Citellus Armatus), Stuart K. Ware Dec 1976

Effect Of Altitude On The Peripheral Degradation Of Thyroxine In The Uinta Ground Squirrel (Citellus Armatus), Stuart K. Ware

Theses and Dissertations

Various methods were employed to detect changes in the peripheral degradation of thyroxine (T4) in adult Uinta ground squirrels (Citellus armatus) collected at two different altitudes (5400 and 9000 feet.) Plasma half-life of injected T4-125I (tl/2) was significantly decreased with altitude, as was T4-125I distribution space (TDS) and T4 degradation and secretion rate (TSR). In vitro deiodination of T4-125I by heart homogenates was not affected, while urinary excretion of thyroxine derived iodide was increased at high altitude 44-70 hours post-injection. Both total and free serum T4 concentrations were reduced at high altitude, although not significantly. The cause of the reduced …

Population Characterization And Feeding Behavior Of A Subtidal Neogastropod, Amphissa Columbiana, Bruce C. Stone Dec 1976

Population Characterization And Feeding Behavior Of A Subtidal Neogastropod, Amphissa Columbiana, Bruce C. Stone

Theses and Dissertations

The neogastropod Amphissa columbiana is found abundantly in subtidal areas of the San Juan Archipelago. Two populations studied were composed of distinct age classes of sexually immature and mature specimens. Reproduction appears to take place in the fall by snails at least two years old. Amphissa is a chemoreceptive scavenger that usually feeds on carrion and on dead and injured animals. Feeding behavior is mediated by chemical attractants from dead and traumatized tissue. An unusual feeding association is formed where Amphissa congregate around feeding predators to share their meals. A specific defense mechanism is deployed by Amphissa especially in response …

Potential Diets For Carp Production, Rex Carlton Infanger Dec 1976

Potential Diets For Carp Production, Rex Carlton Infanger

Theses and Dissertations

The objective of this study was to determine the feasibility of raising carp on pig manure and coli, Brassica campestris. The use of pig feces as a source of fish food has been questioned by researchers (Hickling 1968). Coli was selected for dietary intake by fish since it is used for human consumption by the Indians of Guatemala. Commercial fish food (Silver Cup) was used for a control diet. These diets were both combined and used as a single source of food.
