Strategies For The Preservation Of Rare Plants, Arthur H. Holmgren

Great Basin Naturalist Memoirs

Preservation of the habitat is the only logical strategy to save endangered species from early extinction. Ecological amplitudes of rare species are very narrow, so transplantation to such alien sites as botanical gardens is not a solution. Protection may not be the answer. We must learn as much as we can about the biology of the species in question, in the field and under laboratory conditions. The first steps must be to determine the distribution. This would be followed by analysis of soils by means of physical and chemical studies. Pollination ecology, associated species, phenological records, and genetic and cytological …

Some Reproductive And Life History Characteristics Of Rare Plants And Implications Of Management, K. T. Harper

Great Basin Naturalist Memoirs

Analysis of the vascular floras of Utah, Colorado, and California suggest that a syndrome of life form and reproductive characteristics separates rare and common species. Woody plants are heavily underrepresented, and herbs are overrepresented on the official lists of endangered and/or threatened plants of the floras considered. Few of the rare species are descended from wind-pollinated ancestors, but instead are derived from the insect-pollinated stock. Theory suggests that many of the rare taxa will ultimately be shown to be self-pollinated. The date show a tendency for rare species to be better represented among taxa having bilaterally symmetrical as opposed to …

Rare Aquatic Insects, Or How Valuable Are Bugs?, Richard W. Baumann

Great Basin Naturalist Memoirs

Insects are an important element in the analysis of aquatic ecosystems, (1) because the limited dispersal abilities of many aquatic species means that they must make a living under existing conditions, and (2) because they are often sensitive to slight changes in water and stream quality, thus making excellent indicators of the physical and chemical conditions in a system. Examples of rare, ecologically sensitive species are presented from the Plecoptera, Ephemeroptera, and Trichoptera. Detailed studies of rare aquatic insect species should produce important information on critical habitats that will be useful in the protection of endangered and threatened species in …

Endangered And Threatened Fishes Of The West, James E. Deacon

Great Basin Naturalist Memoirs

The endangered and threatened fish fauna of the United States exhibits problems resulting primarily from habitat modification by man. The evolutionary history of the fauna has left it especially sensitive to biotic interactions. In addition, many forms are of such restricted distribution that the entire taxon can be destroyed by very minor perturbations. The effects of habitat modification on woundfin and roundtail chub in the Virgin River of Utah, Arizona, and Nevada are discussed. Parasitism by Lernea on White River springfish is shown to coincide with population decline in some, but not all, cases. Population declines of Pahrump killifish are …

Endangered Species: Costs And Benefits, Edwin P. Pister

Great Basin Naturalist Memoirs

Biologists are often placed in the difficult position of defending a threatened habitat or animal with vague reasoning and faulty logic, simply because they have no better rationale at their immediate disposal. This places them at a distinct disadvantage and literally at the mercy of resource exploiters and their easily assignable dollar values. Although the initial dollar cost of delaying precluding "developing" may be significant, the long-term benefits of saving the biological entities which might otherwise be destroyed are likewise great and are measurable in concrete terms which society is only now beginning to appreciate. Case histories are presented, a …

Ye Are Free . . ., Thomas W. Russell

Issues in Religion and Psychotherapy

"Ye are free, ye are permitted to act for yourselves." Helaman 14:30

The thesis of this paper is that free agency is not only central to our faith and salvation, but is also critical to effective therapeutic care.

Our Father in Heaven has given us the ability to make choices. Some of these choices are healthy and help us grow while others are destructive, stop us from living full lives, and can lead to insanity.

Effective therapy enables us to identify the choices we have made and then decide if we want to make new choices.

Potential Use Of Great Salt Lake Water For Lobster Culture, Roger W. Mickelsen, Richard A. Heckmann, Rex C. Infanger

Great Basin Naturalist

Three experiments were conducted to determine if water from the Great Salt Lake altered in chemical composition and dilution can be used successfully to sustain a species of hermit crab Pagarus sp. and the American Lobster (Homarus americanus). Great Salt Lake water altered by freshwater dilution will not sustain the hermit crab or the American lobster. Great Salt Lake water can be altered chemically by dilution to support growth of the American lobster.

American lobsters maintained in Instant Ocean synthetic sea water (control) grow at a more rapid rate than animals sustained in altered Great Salt Lake water. …

Competitive Displacement As A Factor Influencing Phytoplankton Distribution In Utah Lake, Utah, Lorin E. Squires, Mark C. Whiting, Jack D. Brotherson, Jack D. Rushforth

Great Basin Naturalist

Phytoplankton studies during the summer of 1974 in Utah Lake, Utah, demonstrated the development of disjunct distributions of Aphanizomenon flos-aquae and Ceratium hirundinella. Differential response to environmental factors and competitive displacement are proposed as probable explanations for this phenomenon.

Heating-Effect Minimization In Dye Lasers, Kenneth Lee Matheson, James M. Thorne

Faculty Publications

Optical pumping of dye lasers deposits heat nonuniformly in the active medium. Because the refractive index of a liquid or gas is a function of temperature, gradients are created which refract the laser beam. This effect is sometimes serious enough to quench laser action. In this paper, we evaluate the effects caused by optical pumping with a coaxial flashlamp and suggest ultraviolet absorbers and wavelength shifters as materials for minimizing the problem

Chemical Composition Of Some Important Plants Of Southeastern Utah Summer Ranges Related To Mule Deer Reproduction, Jordan C. Pederson, K. T. Harper

Great Basin Naturalist

Chemical composition of some major forage plants of mountain summer ranges of southeastern Utah is reported. Grasses are shown to contain significantly less nitrogen, phosphorus, potassium, calcium, and magnesium than either forbs or shrubs. Forbs and shrubs are demonstrated to differ significantly only in potassium content; forbs tested contained more potassium than shrubs. The chemical composition of the forage plants is discussed in relation to mule deer reproductive rates. It is concluded that protein and mineral content of the forage of the two ranges considered (the LaSal and Henry mountains) is less likely to affect reproductive rates than is the …

Ecological And Community Relationships Of Eriogonum Corymbosum (Polygonaceae) In The Uinta Basin, Utah, Jack D. Brotherson, Karen J. Brotherson

Great Basin Naturalist

Ecological and community relationships of 10 different plant communities in the Uinta Basin, Utah, where Eriogonum corymbosum was found to grow were studied and described. Each community was sampled to determine the amount of ground cover, percent composition, frequency, and density of participating species. Physical site factors, viz., soil texture, total soluble salts, pH, cation exchange capacity, and amounts of calcium, magnesium, potassium, and sodium were determined. The 10 communities were compared to determine the degree of similarity between them. Correlations between individual plant species and measurable characteristics of the community were attempted. Evidence is presented that the distributional patterns …

Review Of Tularemia In Utah And The Great Basin, Harold E. Stark

Great Basin Naturalist

This is a compilation of tularemia research conducted in Utah, particularly at U.S. Army Dugway Proving Ground (DPG), Utah, and an evaluation of this information in relation to the current status of tularemia studies. A brief history of tularemia in Utah and a review of field and laboratory studies are included.

Human cases of tularemia occur throughout Utah during all seasons of the year. An analysis of recent human disease reveals a concentration of cases in rural areas, with a greater seasonal occurrence in late summer and early fall.

Vegetation Response To A Moisture Gradient On An Ephemeral Stream In Central Arizona, Deborah Ann Bloss, Jack D. Brotherson

Great Basin Naturalist

Ecological aspects of desert vegetation in relation to a moisture gradient along an ephemeral stream in central Arizona were investigated. The stream channel, flood plain, and north-, west-, south-, east-facing slopes represent a moisture gradient going from mesic to xeric conditions. Vegetation in some areas of the stream channel intergraded into flood plain vegetation, which in turn intergraded into slope vegetation types. In other areas there were sharp delineations between stream channel and flood plain and between flood plain and slope. Trees and legume species preferred midmoisture habitats, but forbs, shrubs, and succulents preferred dryer areas. Family groups like the …

Ecological Distribution Of Rodents In Canyonlands National Park, Utah, David M. Armstrong

Great Basin Naturalist

Studies of microhabitat of 14 species of rodents by cluster analysis suggested that the diverse landscapes of Canyonlands National Park, Utah, include six broad "habitat-types": (1) rimrock; (2) desert shrublands; (3) saxicoline woodland and sagebrush; (4) oakbrush; (5) riparian deciduous woodland; and (6) grasslands. Perognathus parvus and Neotoma cinerea were the species most strongly associated with single "habitat-types," desert shrub and saxicoline woodland, respectively. Peromyscus maniculatus and P. truei were the species associated with the broadest ranges of habitats. The rodents with the most similar habitats were Neotoma mexicana and Peromyscus boylii; Eutamias quadrivittatus, P. truei, and P. crinitus; Ammospermophilus …

Variation In Hemoglobin Types In The Deer Mouse (Peromyscus Maniculatus) Along An Altitudinal Gradient, David Wasserman, Donald J. Nash

Great Basin Naturalist

Deer mice (Peromyscus maniculatus) were captured along an altitudinal gradient that extended from 5,000 feet (1524 m) up to 11,000 feet (3353 m) in central Colorado during August and early September, 1976. Starch gel electrophoresis of deer mouse hemoglobin followed no clear trend that would indicate that slight biochemical differences in the molecule help facilitate adaptation to the decreased pO₂ that exists at that altitude.
