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. …

Ground Nesting And Aggressive Behavior By The Swainson's Hawk (Buteo Swainsoni), Neil D. Woffinden, James A. Mosher

Great Basin Naturalist

A successful ground nesting by Swainson's Hawks, Buteo swainsoni, is reported for central Utah. Unusual aggressive nest defense behavior is described for this ground nesting pair.

Decreases Of Juniper Woodland In The Utah And Salt Lake Valleys Since Settlement, E. M. Christensen, J. D. Brotherson

Great Basin Naturalist

Although pinyon-juniper woodland is common throughout most of Utah, it is less so in Utah and Salt Lake valleys. Even so, stands do occur in the valleys and are known to have been there since presettlement times. Three such stands occurring along the eastern sections of the valleys have shown major decreases in area since settlement times, and one has all but disappeared. Their disappearance is attributed to early use for fuel, agricultural, and urbanization purposes.

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.

Response Of Reptile Populations To Different Land Management Practices On The Idaho National Engineering Laboratory Site, Timothy D. Reynolds

Great Basin Naturalist

Populations of reptiles were examined in grazed and ungrazed habitats dominated by sagebrush (Artemisia tridentata) or by crested wheatgrass (Agropyron cirstatum) on the Idaho National Engineering Laboratory (INEL) Site in southeastern Idaho. The sagebrush lizard (Sceloporus graciosus) and the short-horned lizard (Phrynosoma douglassi) were the only species of reptiles encountered in sufficient numbers to permit statistical analysis. Both of these species preferred sagebrush habitats to areas dominated by crested wheatgrass. The sagebrush lizard was most abundant in the native, ungrazed, sagebrush habitat, and the short-horned lizard was most plentiful in the sheep-grazed …

Flora Of The Lee Creek Valley, Alberta, Keith R. Shaw

Great Basin Naturalist

The floristic composition of the Lee Creek valley in southwestern Alberta, Canada, is presented. The valley flora consists of 299 species of vascular plants representing 173 genera and 46 families. The flora is dominated by forbs (73 percent), followed by grasses (24 percent), shrubs (12 percent), and trees (11 percent). The valley of Lee Creek is divided into upper and lower sections on the basis of elevational, climatic, and biotic differences. Floristic richness of the Lee Creek valley is quite evenly divided between the upper and lower valleys: 105 species limited to the upper valley, 95 to the lower valley, …

Competition Between Harvester Ants And Rodents In The Cold Desert, Dan S. Landeen, Clive D. Jorgensen, H. Duane Smith

Great Basin Naturalist

Local distribution patterns of three rodent species (Perognathus parvus, Peromyscus maniculatus, Reithrodontomys megalotis) were studied in areas of high and low densities of harvester ants (Pogonomyrmex owyheei) in Raft River Valley, Idaho. Numbers of rodents were greatest in areas of high ant-density during May, but partially reduced in August; whereas, the trend was reversed in areas of low ant-density. Seed abundance was probably not the factor limiting changes in rodent populations, because seed densities of annual plants were always greater in areas of high ant-density. Differences in seasonal population distributions of rodents between areas of high …

Vegetative And Edaphic Factors Affecting Abundance And Distribution Of Small Mammals In Southeast Oregon, George A. Feldhamer

Great Basin Naturalist

The relationships between vegetative and edaphic habitat factors and the local distribution and abundance of small mammals on Malheur National Wildlife Refuge, Harney County, Oregon, were examined between July 1973 and June 1975. Of 16 species of small mammals captured, deer mice (Peromyscus maniculatus), montane voles (Microtus montanus), Great Basin pocket mice (Perognathus parvus), and least chipmunks (Eutamias minimus) comprised 90.1 percent of the individuals. The physiognomy of the vegetation was a factor in the distribution of rodent species other than deer mice. Pocket mice and chipmunks were restricted to the communities …

Climates Of Fescue Grasslands Of Mountains In The Western United States, T. Weaver

Great Basin Naturalist

Climates of fescue grasslands were described by summarizing USDC Weather Bureau records of representative sites. Mean temperatures of the warmest month declined from 18 to 14 C, average annual precipitation increased from 40–50 to 170 cm, and the number of arid months in an arbitrarily defined dry year declined from 3 to 1–2 as one moves from Festuca arizonica (14 stations) to F. scabrella (15) to F. idahoensis (17) to F. thurberi (6) to F. viridula (9). Climates of the grasslands are sufficiently like those of the Pseudotsuga menziesii and Abies lasiocarpa zones of the northern Rocky Mountains to make …

Food Habits Of Burrowing Owls In Southeastern Idaho, R. L. Gleason, T. H. Craig

Great Basin Naturalist

Food habits of a population of the Burrowing Owl (Athene cunicularia) at the Idaho National Engineering Laboratory, Butte County, were studied. The 421 pellets examined yielded 2,436 prey items of at least 22 prey species. Invertebrates, largely insects, constituted 91 percent of the total prey items, but only 29 percent of the total biomass; mammals constituted 8 percent of the prey items, but 68 percent of the biomass. The prey were mostly nocturnal species; diurnal species were poorly represented.

Nearctic Stonefly Genera As Indicators Of Ecological Parameters (Plecoptera: Insecta), Richard W. Baumann

Great Basin Naturalist

Selected stonefly genera found in North America are classified as to their occurrence in: cold lotic, warm lotic, or lentic habitats. Most genera occur only in the cold lotic, but several occur both in cold and warm lotic systems. Few are found exclusively in warm lotic habitats and almost none in lentic. Lake or true lentic inhabits are found to usually be cold lotic species which have adapted to life in the wave-washed shores of cold mountain lakes.

Even though data at the specific level would be even more useful, especially where different faunal regions are involved, stoneflies are probably …

Economic Issues Of Groundwater Management, B. Gardner Delworth

Faculty Publications

This is a coaceptual rather than an empirical paper with the primary focus on raising a set of economic issues faced by any authority charged with managing a groundwater aquifer. I will utilize the technique of making simplifying, albeit unrealistic, assumptions in order to establish easily and clearly the relevant economic principles. Some of the assumptions will be relaxed later to achieve greater realism. It is assumed that the hydrologic dimensions of the groundwater system are known and that the management authority has the power to enforce whatever rules it deems appropriate. There are a host of problems associated with …

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

Don Diego De Silva: Spanish American Ambassador In England, 1564-1568, Jack K. Nielsen

Theses and Dissertations

A resident ambassador in the late sixteenth century faced many challenges, among which were: gathering, evaluating, and relaying useful information; performing negotiations on behalf of his principal; and calming troubled waters at the foreign court. The way in which he .faced these challenges determined the extent of the ambassador's success.

Jon Jiego Guzman de Silva, Spanish ambassador in Zngland .from 1564-1568, faced these challenges and others because he was a staunch Catholic at a Protestant court. Although he was able to maintain his position at court for four years, he was not totally successful. He forwarded much useful and correct …
