On The Taxonomic Status Of Eriogonum Robustum (Polygonaceae), A Rare Endemic In Western Nevada, Kristin F. Kuyper, Ulla Yandell, Robert S. Nowak Mar 1997

On The Taxonomic Status Of Eriogonum Robustum (Polygonaceae), A Rare Endemic In Western Nevada, Kristin F. Kuyper, Ulla Yandell, Robert S. Nowak

Great Basin Naturalist

Evidence from the morphology, genetics, and biogeography of a rare endemic from western Nevada, Erigonum robustum, is presented to determine the most accurate taxonomic classification. Previous authors have classified E. robustrum Greene both as a species and as a variety E. lobbii Torrey & Gray. However, results of a morphometric comparison for 9 characters establish that significant morphological differentiation exists between E. robustum and E. lobbii. In addition, results of a genetic study using protein electrophoresis indicated that genetic differentiation may exist between these 2 taxa. Furthermore, the 2 taxa are geographically, ecologically, and reproductively isolated. Finally, the …

Ecophysiology Of The Temperate Desert Halophytes: Allenrolfea Occidentalis And Sarcobatus Vermiculatus, James D. Trent, Robert R. Blank, James A. Young Mar 1997

Ecophysiology Of The Temperate Desert Halophytes: Allenrolfea Occidentalis And Sarcobatus Vermiculatus, James D. Trent, Robert R. Blank, James A. Young

Great Basin Naturalist

Numerous basins of the intermountain area often have extensive playa surfaces that are nearly devoid of vegetation. Margins of these playas support sparse communities dominated by chenopod shrubs Allenrolfea occidentalis (iodine bush) and Sacrobatus vermiculatus (black greasewood). These plants establish and persist in an environment where halomorphic soils induce extreme osmotic stress and atmospheric precipitation is very low and erratic and occurs largely during the winter when temperatures are too low for growth. We measured net CO2 assimilation rates, leaf conductances, transpiration rates, water-use efficiencies, and stem xylem potentials for these two C3 species. Data were collected in above-average …

Evaluation Of Fish Diplostomatosis In Strawberry Reservoir Following Rotenone Application: A Five-Year Study, Victor H. Inchausty, Richard A. Heckmann

Great Basin Naturalist

Strawberry Reservoir, Wasatch County, Utah, was treated with rotenone in August 1990. For 5 yr following treatment, about 2000 fish from 5 different species were examined for eye metacercariae (Diplostomum). Incidence dropped from 88.0% before to 0.1% after treatment for cutthroat trout (Oncorhynchus clarki), from 93.0% to 0.1% for rainbow trout (O. mykiss), and from 19.0% to 10.0% for redside shiner (Richardsonius balteatus). Average numbers of metacercariae per eye also dropped from 6.8 to 0.1 for cutthroat trout, from 23.1 to 0.1 for rainbow trout, and from 18.9 to 0.1 for redside …

Dispersal Characteristics Of The Yucca Weevil (Scyphophorus Yuccae) In A Flowering Field Of Yucca Whipplei, Travis E. Huxman, Kimberly A. Huxman, Marc R. Stamer Mar 1997

Dispersal Characteristics Of The Yucca Weevil (Scyphophorus Yuccae) In A Flowering Field Of Yucca Whipplei, Travis E. Huxman, Kimberly A. Huxman, Marc R. Stamer

Great Basin Naturalist

Dispersal characteristics were measured for a population of yucca weevils (Scyphophorus yuccae) in a plot consisting of flowering and nonflowering Yucca whipplei. We compared weevil dispersal to yucca distribution, phenology, and caudex temperature. We also compared weevil movement to wind patterns and time of day. Captured weevils were marked and released into both flowering and nonflowering home plants in the field. Distance traveled, weevil flight direction, and target plant characteristics were recorded. We found that yucca weevils moved only between 1600 h on the release day and 0600 h of the following day. We recorded movement from …

A Mormon Cultural Study Of Musical Preference, Alden L. Weight Jan 1997

A Mormon Cultural Study Of Musical Preference, Alden L. Weight

Theses and Dissertations

Music is an important yet relatively unnoticed part of the everyday world almost all of us take for granted. Whether in the car, watching television, shopping, at work or at home, even waking up in the morning or going to sleep at night, and so forth, music surrounds us, soothes us, disturbs us, and occasionally goes so far as to persuade us. Although music plays a significant role in many areas of life, its relationship to society is especially evident in the religious sphere. Therefore, the religious sphere is an ideal place to examine what music does and what it …

The Effect Of Ultrasonic Frequency Upon Enhanced Killing Ofp. Aeruginosa Biofilms, Zhen Qian, Richard D. Sagers, William G. Pitt Jan 1997

The Effect Of Ultrasonic Frequency Upon Enhanced Killing Ofp. Aeruginosa Biofilms, Zhen Qian, Richard D. Sagers, William G. Pitt

Faculty Publications

It is widely recognized that the bacteria sequestered in a biofilm on a medical implant are much more resistant to antibiotics than their planktonic counterparts. Recent studies have shown that application of antibiotic along with low power ultrasound significantly increases the killing of planktonic bacteria by the antibiotic. Herein is reported a similar application of antibiotic and ultrasound to sessile bacteria in biofilms of Pseudomonas aeruginosa on a polyethylene substrate. Biofilm viability was measured after exposure to 12 μg/ml gentamicin sulfate and 10 mW/cm2 ultrasound at frequencies of 70 kHz, 500 kHz, 2.25 MHz, and 10 MHz. The results …

The nutritional value for the following species have been determined: P.pallida, P.laevigata var. andicola, P.flexuosa, P.nigra, P.alba of the genus Proposis. To obtain this purpose surveys were done about the use and consumption of the Carob Tree in the High and Central Valleys of the Cochabamba Department. As a result of the surveys it was determined that the consumption of the pods made up for 54% of human nourishment. The species that were consumed the most were P.pallida and P.laevigata var. andicola. Within the uses of these leguminous pods, the pods are directly consumed in their raw form and on …


Mormon Women's Sense Of Empowerment, Stace Hucks Christianson Jan 1997

Mormon Women's Sense Of Empowerment, Stace Hucks Christianson

Theses and Dissertations

This research focuses on the empowering experiences of LDS women within the patriarchal structure as organized by the LDS church. Women in the LDS church empower themselves by drawing both external and internal resources. The degree of flexibility that leaders and member of the LDS church adopt externally influences the degree of empowerment that LDS women. The more internal factors an LDS woman adopts the greater her internal sense of empowerment.


A Field Study Of The Nesting Ecology Of The Thatching Ant, Formica Obscuripes Forel, At High Altitude In Colorado, John R. Conway Nov 1996

A Field Study Of The Nesting Ecology Of The Thatching Ant, Formica Obscuripes Forel, At High Altitude In Colorado, John R. Conway

Great Basin Naturalist

A field study of the thatching ant, Formica obscuripes Forel, at 2560 m elevation in Colorado provided information on mound density, composition, dimensions, and temperatures; worker longevity; and mite parasitization. Density was 115 mounds/ha. Mounds had 1–52 entrances and Peromyscus fecal pellets in the thatch. Mounds conserved heat and exhibited thermal stratification. Excavations of 4 nests revealed depths of 0.3 m to almost 1 m, novel myrmecophiles, and 0–198 wingless queens per nest. Marking experiments demonstrated that some workers overwinter and live more than a year.


Gas Exchange, Δ13C, And Heterotrophy For Castilleja Linariifolia And Orthocarpus Tolmiei, Facultative Root Hemiparsites On Artemisia Tridentata, Lori A. Ducharme, James R. Ehleringer Nov 1996

Gas Exchange, Δ13C, And Heterotrophy For Castilleja Linariifolia And Orthocarpus Tolmiei, Facultative Root Hemiparsites On Artemisia Tridentata, Lori A. Ducharme, James R. Ehleringer

Great Basin Naturalist

Gas exchange and carbon isotope ratios were measured on 2 facultative hemiparasites, Castilleja linariifolia Benth. (Indian paintbrush; Scrophulariaceae) and Othrocarpus tomiei H. & A. (Tolmie owl clover; Scrophulariaceae), and their Artemisia tridentata L. (big sagebrush; Asteraceae) hosts. Photosynthetic rates differed greatly between years; rates in 1995 were more than double those in 1994, likely due to more precipitation and less water stress during 1995. Despite the difference in precipitation, photosynthetic rates for C. linariifolia were not different from those of their hosts for either year. However, carbon isotope ratios of C. linariifolia and O. tolmiei were up to 3% more …


Helminths Of The Southwestern Toad, Bufo Microscaphus, Woodhouse's Toad, Bufo Woodhousii (Bufonidae), And Their Hybrids From Central Arizona, Stephen R. Goldberg, Charles R. Bursey, Keith B. Malmos, Brian K. Sullivan, Hay Cheam Nov 1996

Helminths Of The Southwestern Toad, Bufo Microscaphus, Woodhouse's Toad, Bufo Woodhousii (Bufonidae), And Their Hybrids From Central Arizona, Stephen R. Goldberg, Charles R. Bursey, Keith B. Malmos, Brian K. Sullivan, Hay Cheam

Great Basin Naturalist

The gastrointestinal tracts, lungs, and urinary bladders from 77 Bufo microscaphus, 61 Bufo woodhousii, and 8 of their hybrids were examined for helminths. One species of trematode (Glypthelmins quieta), 1 species of cestode (Distoichometra bufonis), and 5 species of nematodes (Aplectana incerta, A. itzocanensis, Rhabdias americanus, Physaloptera sp., and Physocephalus sp.) were found. The greatest prevalence (41%) and mean intensity (231.7) were recorded for Aplectana incerta in Bufo woodhousii. It appears hybrids harbor fewer parasites than either parent species.
