Frequency Distribution And Correlation Among Mineral Elements In Lycium Andersonii From The Northern Mojave Desert, A. Wallace, E. M. Romney, G. V. Alexander, J. E. Kinnear Oct 1980

Frequency Distribution And Correlation Among Mineral Elements In Lycium Andersonii From The Northern Mojave Desert, A. Wallace, E. M. Romney, G. V. Alexander, J. E. Kinnear

Great Basin Naturalist Memoirs

Two hundred samples of leaves of Lycium andersonii A. Gray, each representing one plant and divided among six different locations, were assayed by emission spectrography. Information for 12 different elements is reported in terms of concentrations, frequency distribution, correlations, and some soil characteristics. The objective was to ascertain the nature of variability for mineral elements within a species. Composition varied significantly for all 12 elements among locations, all within about 20 km. At least part of the variation was due to soil characteristics. Samples from Rock Valley were highest in K, Na, and Li, which effect is associated with volcanic …

Urs Schwarz, The Eye Of The Hurricane: Switzerland In World War Two, Heinz K. Meier

Swiss American Historical Society Newsletter

"Switzerland in World War II" has become a favorite object of investigation and subject of treatment by Swiss journalists, publicists, political scientists and historians. The flood of articles and monographs on every conceivable aspect of that topic has become so overwhelming as to make it almost impossible for one person to keep track of it, let alone read and digest it. And yet, according to Urs Schwarz, ther is a gap in this outpouring of hsitorical literature: There are no English language accounts on the role of neutral Switzerland in World War II. His Book The eye of the Hurricane …

Jacob Burckhardt, The Historian, As Analyst Of His Age, Walter L. Mullen

Swiss American Historical Society Newsletter

Often the historian is faced with the question of how the study of the past relates to the present. Even when Leopold von Ranke's admonition is followed, and we try to tell history "as it essentially was" and eliminate subjectivity, purely personal opinions are difficult to keep out of formal academic work. Even when objectivity is attempted, the historian will have personal convictions about the object of his study in relation to his own existence.

Spatiotemporal Variation In Phenology And Abundance Of Floral Resources On Shortgrass Prairie, V. J. Tepedino, N. L. Stanton Sep 1980

Spatiotemporal Variation In Phenology And Abundance Of Floral Resources On Shortgrass Prairie, V. J. Tepedino, N. L. Stanton

Great Basin Naturalist

Phenology and abundance of the floral resources used by bees and other flower-visiting insects were recorded weekly from permanent quadrats for two years on two shortgrass prairie sites in the Laramie Basin, Wyoming. Each site was composed of three distinct plant communities. Results suggest considerable spatiotemporal variability in floral resources. Specifically, most species at both sites showed the following temporal variation: (1) bloom times between one and two weeks earlier in the second year; (2) differences of approximately 1–2 weeks in bloom span between years; (3) substantial differences in abundance of flowers between years. Species blooming during the last half …

Poisonous Plants Of Utah, Jack D. Brotherson, Lee A. Szyska, William E. Evenson Sep 1980

Poisonous Plants Of Utah, Jack D. Brotherson, Lee A. Szyska, William E. Evenson

Great Basin Naturalist

A list of the major livestock-poisoning plants has been compiled for the state of Utah. Two hundred fifteen taxa representing 36 families, 119 genera, and 209 species occur within the state. Forty-one percent are from two families, the Asteraceae and the Fabaceae. The remaining families of major importance are: Poaceae, Ranunculaceae, Solanaceae, Chenopodiaceae, Brassicaceae, Ascelpiadaceae, Liliaceae, and Euphorbiaceae. Sixty-nine percent of the genera occur with a single species. Thirty-three percent of the taxa are introduced to the state. Most of the plants are insect pollinated; 57 percent are herbaceous perennials.

Most livestock poisoning occurs during the spring. This is due …


Dog Owners And Hydatid Disease In Sanpete County, Utah, Peter M. Schantz, Ferron L. Andersen Sep 1980

Dog Owners And Hydatid Disease In Sanpete County, Utah, Peter M. Schantz, Ferron L. Andersen

Great Basin Naturalist

A questionnaire survey was conducted in Sanpete County, Utah, to determine the knowledge of dog owners concerning hydatid disease and an identification of some basic sheep management practices there. The households surveyed included 21 (Group I) that had one or more dogs infected with Echinococcus granulosus tapeworms at more than one annual field clinic, and 19 others (Group II) that had one or more dogs infected when the study first began in 1971–72, but had not had any infected dogs identified at field clinics during subsequent years. The results showed that 92.5 percent of households knew the cause of the …


The Successional Status Of Cupressus Arizonica, Albert J. Parker Sep 1980

The Successional Status Of Cupressus Arizonica, Albert J. Parker

Great Basin Naturalist

Several investigations (size-class analysis, age-determination inquiries, and germination tests) suggest that Cupressus arizonica of southeastern Arizona is a pioneer species. The tree requires disturbance to remove or reduce soil litter, which otherwise inhibits the reproduction of the species. Reduction of light intensity caused by canopy closure appears to be less important than litter accumulation in restricting C. arizonica reproduction. Following disturbance, successful establishment of seedlings may occur over an extended period (50 to 100 years), as litter gradually accumulates. The absence of C. arizonica seedlings in present populations suggest that fire suppression policies on federal lands where C. arizonica occurs …


Temporal Activity Patterns Of Dipodomys Ordii Population, Clive D. Jorgensen, H. Duane Smith, James R. Garcia Sep 1980

Temporal Activity Patterns Of Dipodomys Ordii Population, Clive D. Jorgensen, H. Duane Smith, James R. Garcia

Great Basin Naturalist

Temporal activity patterns for Dipodomys ordii were generally bimodal during the summer, with the highest peak occurring during early predawn hours when conditions were optimum for water conservation. Removal of dominant members in the population resulted in a substantial shift in the activity pattern to increased activity during the evening hours.


Observations On Seasonal Variation In Desert Arthropods In Central Nevada, Robert D. Pietruszka Sep 1980

Observations On Seasonal Variation In Desert Arthropods In Central Nevada, Robert D. Pietruszka

Great Basin Naturalist

Pitfall and Malaise trap collections from terrestrial arthropod populations in central Nevada were analyzed for four trapping periods during the 1978 growing season. Mites (Acarina) and ants (Formicidae) were the taxa represented by the largest numbers of individuals in pitfall trap collections throughout the season; Malaise collections were composed mainly of aerial taxa (largely Diptera and Hymenoptera). Peak arthropod abundance was recorded during mid-June. Collection diversities for both trapping methods were generally low due to the abundance of a few taxa. Evidence for spatial heterogeneity in arthropod populations was meager; temporal heterogeneity in these populations, however, was more apparent.


A Comparison Of Epiphytic Diatom Assemblages On Living And Dead Stems Of The Common Grass Phragmites Australis, Judith A. Grimes, Larry L. St. Clair, Samuel R. Rushforth Sep 1980

A Comparison Of Epiphytic Diatom Assemblages On Living And Dead Stems Of The Common Grass Phragmites Australis, Judith A. Grimes, Larry L. St. Clair, Samuel R. Rushforth

Great Basin Naturalist

Diatoms epiphytic on Phragmites australis (Cav.) Trin. ex Steaded stems were collected from a single clone at the southern end of Provo Bay, Utah Lake, Utah. Diatom populations from both living and dead stem sections were analyzed. Species diversity in each sample was high, indicating that the stems provide a relatively stable habitat for diatom epiphytes. Of the 23 genera found, only Gomphonema and Navicula showed significant trends toward stem preference. The diatoms in this study support the current view that Utah Lake is a slightly saline, eutrophic system.


Comparative Floral Biology Of Penstemon Eatonii And Penstemon Cyananthus In Central Utah: A Preliminary Study, Lucinda Bateman Sep 1980

Comparative Floral Biology Of Penstemon Eatonii And Penstemon Cyananthus In Central Utah: A Preliminary Study, Lucinda Bateman

Great Basin Naturalist

A comparison of the floral visitors of two closely related plant species, Penstemon cyananthus and P. eatonii suggests that flower shape and color may affect the number and type of pollinators, and the ability of the plant to set fruit. Penstemon cyananthus, which is most attractive to hymenopteran visitors, has a blue flower, large in diameter, that is positioned as a convenient "landing pad." Although many types of insects visit the flower, the transport of pollen directly to flowers of another individual of the same species is somewhat inefficient, since fruiting success is low (66.7 percent). The tubular red flowers …


Differential Habitat Utilization By The Sexes Of Mule Deer, Michael M. King, H. Duane Smith Sep 1980

Differential Habitat Utilization By The Sexes Of Mule Deer, Michael M. King, H. Duane Smith

Great Basin Naturalist

Habitat segregation trends have been observed and published for the sexes of mule deer (Odocoileus hemionus) based on elevation and slope exposure. Despite these brief descriptions, quantitative studies on habitat segregation by the sexes of mule deer are lacking. Results of research conducted in central Utah indicated no significant difference in elevation positions used by males, but did show significant difference in utilization of study sites based on slope exposure, relative percentage forb cover, and relative percentage hiding cover. Males were most common at sites characterized by low forb abundance and hiding cover, and on south-facing exposures. Females …

A Self-Pollination Experiment In Pinus Edulis, Ronald M. Lanner Sep 1980

A Self-Pollination Experiment In Pinus Edulis, Ronald M. Lanner

Great Basin Naturalist

Controlled pollinations were performed on four pinyons (Pinus edulis Engelm.) to compare the results of selfing and outcrossing. Final cone size was the same under both treatments. There was no significant difference in number of seeds per cone. Filled-seed yields averaged 14.4 percent in selfings and 90.5 percent in outcrossings. Relative self-fertility averaged about 15 percent, a level comparable with that of other pine species studied.
