Effect Of Irrigation On Survival Of Third-Stage Haemonchus Contortus Larvae (Nematoda: Trichostrongylidae), Graham R. Bullick, Ferron L. Andersen
Effect Of Irrigation On Survival Of Third-Stage Haemonchus Contortus Larvae (Nematoda: Trichostrongylidae), Graham R. Bullick, Ferron L. Andersen
Great Basin Naturalist
During May through October 1976, samples of sheep pellets containing laboratory-reared, thirdstage Haemonchus contortus larvae were placed on irrigated and nonirrigated pasture plots at Provo, Utah. Periodically thereafter, grass clippings, soil scrapings, and remaining pellets were collected and baermannized to determine their comparative survival from the two environments. Water was added to the irrigated plots in accordance with a weekly sprinkling regime designed to furnish sufficient moisture to maintain pasture grass in this semiarid region. Meteorologic measurements were collected daily from both irrigated and nonirrigated sections. During the year the nonirrigated section received a total of 131 mm of precipitation, …

Mountain Ants Of Nevada, George C. Wheeler, Jeanette Wheeler
Great Basin Naturalist
Introductory topics include "The High Altitude Environment," "Ants Recorded from High Altitudes," "Adaptations of Ants," "Mountain Ants of North America," and "The Mountains of Nevada." A Nevada mountain ant species is defined as one that inhabits the Coniferous Forest Biome or Alpine Biome or the ecotone between them. A table gives a taxonomic list of the mountain ants and shows the biomes in which they occur; it also indicates whether they occur in lower biomes. This list comprises 50 species, which is 28 percent of the ant fauna we have found in Nevada. Only 30 species (17 percent of the …
New Synonymy And New Species Of American Bark Beetles (Coleoptera: Scolytidae), Part Vii, Stephen L. Wood
New Synonymy And New Species Of American Bark Beetles (Coleoptera: Scolytidae), Part Vii, Stephen L. Wood
Great Basin Naturalist
New synonymy of American Scolytidae is proposed as follows: Coccotrypes cyperi (Beeson) ( = Thamnurgides indicus Eggers), Pityophthorus attenuatus Blackman ( = Pityophthorus pusillus Wood), Pityophthorus digestus LeConte ( = Pityophthorus aplanatus Schedl), Pseudohylesinus sericeus (Mannerheim) ( = Pseudohylesinus yasamatsui Nobuchi), Xyleborus mutabilis Schedl ( = Xyleborus meridensis Wood). New names are proposed to replace junior homonyms as follows: Pityophthorus indigus for Pityophthorus indigens Wood, 1977 (nec Wood 1976), and Xyloborus devexulus for Xyleborus devexus Wood, 1977 (nec Schedl, 1977). The following species are named as new to science: Conophthorus echinatae (Missouri), Lymantor alaskanus (Alaska), Pityophthorus delicatus (Mexico), P. rubidus …

Vertical Distribution Of Adult Fish In Pyramid Lake, Nevada, Steven Vigg
Vertical Distribution Of Adult Fish In Pyramid Lake, Nevada, Steven Vigg
Great Basin Naturalist
Inshore and limnetic vertical distribution of adult fish in Pyramid Lake, Nevada was determined from late spring to early fall 1977. The benthic (23 m) inshore area exhibited a relatively diverse composition of five species, while the inshore surface and offshore limnetic zones were composed of over 98 percent tui chubs (Gila bicolor). Vertical fish distribution was associated with temperature and zooplankton distribution.

Raptors Of The Uinta National Forest, Utah, James A. Mosher, Clayton M. White, Joseph R. Murphy, M. Alan Jenkins
Great Basin Naturalist
The past and present use of the Uinta National Forest by birds of prey was determined from historical records and surveys conducted during 1973, 1974, and 1975. Data describing the history, present status, and physical characteristics of each nest site were collected, along with the type and intensivity of human activity within a half-mile radius of the nest. In addition, limited data on fall migration of raptors along the Wasatch Front and the food habits of Golden Eagles are presented. Management guidelines, based on the results of this study, are proposed.
The Effects Of Radiation From Uranium Mill Tailings On Tradescantia, E. A. Rechel, W. F. Campbell
The Effects Of Radiation From Uranium Mill Tailings On Tradescantia, E. A. Rechel, W. F. Campbell
Great Basin Naturalist
To assess the potential hazard from radioactive wastes, a plant with known radiosensitivity, Tradescantia clone 02, was grown in radioactive soil obtained from uranium mill tailings. The levels of radiation on these tailings varied from 0.03mR/hr (background) to a maximum of 3.00 mR/hr. Tradescantia grown in soil with a radiation level greater than 0.10 mR/hr evidenced significantly reduced reproductive integrity and fecundity, as measured by the number of stunted hairs per stamen, pollen viability, and numbers of somatic mutations. Based on these data, the radioactivity from uranium mill tailings has the potential to alter normal plant succession due to its …

The Eye Fluke Disease (Diplostomatosis) In Fishes From Utah, Richard A. Heckmann, James R. Palmieri
The Eye Fluke Disease (Diplostomatosis) In Fishes From Utah, Richard A. Heckmann, James R. Palmieri
Great Basin Naturalist
During 1976 and 1977, 798 fish representing 11 species from eight collection sites in Utah were examined for metacercariae of Diplostomum spathaceum, which causes the fish eye fluke disease, diplostomatosis. Eight species were infected. The infection rate ranged from 7 percent of 46 Salmo gairdneri from Soldiers Creek Reservoir to 100 percent in 7 species of fish from four collection sites. Summary charts for four years of data are given for collection sites, piscine hosts in Utah, and fish hosts for Strawberry Reservoir, Utah.

Contributions To The Biology Of The Woundfin, Plagopterus Argentissimus (Pisces: Cyprinidae), An Endangered Species, Jeffrey N. Cross
Contributions To The Biology Of The Woundfin, Plagopterus Argentissimus (Pisces: Cyprinidae), An Endangered Species, Jeffrey N. Cross
Great Basin Naturalist
The woundfin is a small, streamlined, omnivorous cyprinid that is now limited to the Virgin River basin where it was collected in the mainstream and one tributary during the present study. The woundfin occurred most frequently in runs and over sand substrates and less frequently in riffles and over rock substrates. It was common over at least half of its original range within the Virgin River. It was uncommon in the lower mainstream due to habitat alterations and, presumably, predation by and competition with exotic species.
An Addition To The Amphibian Fauna Of California, David A. Mullen, Robert C. Stebbins
An Addition To The Amphibian Fauna Of California, David A. Mullen, Robert C. Stebbins
Great Basin Naturalist
A population of salamanders of the genus Ambystoma has been found at Grass Lake, Siskiyou County, in Northern California. A five-year study has established that the salamanders are reproducing successfully and may represent a relictual population of native amphibians. The Grass Lake area has a sparse human population, which may help to explain how this secretive amphibian could have escaped notice. Attempts to determine the taxonomic position of the Grass Lake salamander, through comparisons of body measurements and coloration with those of other western ambystomatids, were inconclusive. These comparisons suggest, however, a close relationship with the geographically most proximate subspecies, …

Chemical Vapor Deposited Molybdenum Films For Use In Photothermal Conversion, David D. Allred, G. E. Carver, B. O. Seraphin
Chemical Vapor Deposited Molybdenum Films For Use In Photothermal Conversion, David D. Allred, G. E. Carver, B. O. Seraphin
Faculty Publications
High infrared reflectance, coupled with higher solar absorptance, is required for efficient photothermal conversion. Converters can be fabricated by depositing an absorber on a highly reflecting metal. The absorber functions in the visible, yet becomes transparent in the near infrared, allowing the metal to suppress the thermal emittance. Economic considerations demand the use of thin films, rather than bulk materials. The thin film reflector must be capable of withstanding high temperatures of operation. Compatibility of the reflector with the substrate below, and the absorber above, is required for long-time service. Highly reflective silver films suffer reflectance losses by agglomeration, and …
Chemical Vapor Deposited Amorphous Silicon For Use In Photothermal Conversion, David D. Allred, D. C. Booth, M. Janai, G. Weiser, B. O. Seraphin
Chemical Vapor Deposited Amorphous Silicon For Use In Photothermal Conversion, David D. Allred, D. C. Booth, M. Janai, G. Weiser, B. O. Seraphin
Faculty Publications
Efficient photothermal conversion requires surfaces of high solar absorptance and low thermal emittance. This can be accomplished by the tandem action of a good infrared reflector overlaid by a film of sufficient solar absorptance that is transparent in the infrared. Crystalline silicon is a suitable candidate for the absorber layer. Its indirect band gap, however, results in a shallow absorption edge that extends to far into the visible. In contrast, the absorption edge of amorphous silicon is steeper and located farther into the infrared, resulting in a larger solar absorptance. We report on the fabrication of amorphous silicon absorbers by …
An Emulsion Dye Laser, Kenneth Lee Matheson, James M. Thorne
An Emulsion Dye Laser, Kenneth Lee Matheson, James M. Thorne
Faculty Publications
A laser dye which is insoluble in water has been dissolved in hexane and emulsified in a water matrix. When pumped with a nitrogen laser, this mixture was observed to lase. The emulsion is superior to a simple hexane solution because the excellent thermo-optical properties of the water matrix help prevent refractive-index gradients from degrading laser performance. This is a useful characteristic for flash-pumped dye lasers, laser-pumped dye lasers, and liquid filters. Another type of solvent system, a critical solution, is also discussed. For certain dyes, a critical solution has even better thermo-optical properties because of its ability to absorb …

Book Review: Les Derniers Puritains, Pionniers D'Amérique, 1851-1920., Lukas Burckhardt
Swiss American Historical Society Newsletter
Théodore Bost was born in 1834 at Carouge near Genea, emigrated in 1851 to St. Paul, Minnesota, became a farmer in nearby Carver County, stayed in Minnesota until 1887 and then moved to Pomona near Los Angeles and died in California in 1920. His wife, Sophie née Bonjour from Neuchâtel, born in 1835, married him in 1858 and died in 1922. Both stood firmly in the protestant tradition. The Bost family, with its pastors, missionaries and even a pioneer in social work for handicapped children, shows how strongly the religions spirit of Geneva has influenced many lives of its citizens. …
