High Rates Of Photosynthesis In The Desert Shrub Chrysothamnus Nauseosus Ssp. Albicaulis, Tim D. Davis, N. Sankhla, W. R. Andersen, D. J. Weber, B. N. Smith

Great Basin Naturalist

Basic aspects of photosynthesis were investigated in white rubber rabbitbrush (Chrysothamnus nauseosus (Pallas) Britt. ssp. albicaulis), a common C₃ deciduous shrub native to arid regions of the western U.S. Under favorable field conditions, net photosynthesis (P_n) ranged from 36 to 73 mg CO₂ · dm ⁻² · hr⁻¹, which is relatively high for a woody species. The leaves from the actively growing flowering shoots exhibited higher P_n than those on the vegetative shoots. P_n also varied according to the age of the leaves and the location of the plants. P …

Occurrence Of Anisakid Larvae (Nematoda: Ascardidia) In Fishes From Alaska And Idaho, Richard Heckmann, Terry Otto

Great Basin Naturalist

All 25 sablefish (Anoplopoma fimbria) examined from two bays near Sitka, Alaska, were infected with anisakid larvae. There were 1 to 11 larvae per infected fish, with worms encysted in the musculature of the body wall of 5 fish and in the liver of 4 fish. For the other hosts the viscera was the site of infection. Chinook salmon (Onchorhynchus tshawytscha) from Barrow, Alaska, and Obsidian, Idaho, were also infected with anisakid larvae. These data extend the known northern distribution of the anisakids along the Pacific Coast for sablefish and chinook salmon. The pathogenesis of the …

Grass Spider Microhabitat Use In Organ Pipe Cactus National Monument, Arizona, Mark Robert Deutschman

Great Basin Naturalist

The grass spider (Agelena naevia), commonly found in Organ Pipe Cactus National Monument, Arizona, uses rodent burrows located under a shrub canopy more frequently for web construction than burrows located in the open. The average number of prey available in canopy microhabitat was greater than in open microhabitat, and unequal prey abundance may explain spider microhabitat use.

Use Of Radio Transmitter Implants In Wild Canids, Jeffrey S. Green, Richard T. Golightly Jr., Susan Lyndaker Lindsey, Brad R. Leamaster

Great Basin Naturalist

Twelve adult and five juvenile coyotes and 20 adult kit foxes were implanted with radio transmitters using relatively simple surgical procedures. Four foxes were successfully implanted in the field. None of the animals implanted exhibited noticeable behavioral effects, and no deaths were confirmed to result from implantation. Implants were attached to the peritoneum in adult coyotes and kit foxes and were left free-floating within the abdominal cavity of the coyote pups. Both procedures produced satisfactory results. Radio signals transmitted from implants had less range than those from traditional neck collar transmitters. Implants offered benefits unavailable with traditional collar transmitters: no …

Quaternary Paleontology And Paleocology Of Crystal Ball Cave, Millard County, Utah: With Emphasis On Mammals And Description Of A New Species Of Fossil Skunk, Timothy H. Heaton

Great Basin Naturalist

Crystal Ball Cave is located in a small outlier of the Snake Range in Snake Valley 1.7 km (1 mile) west of Lake Bonneville at its highest level. Original vertebrate skeletal material (mostly mammalian) has been found in shallow dry dust 61 m (200 feet) inside the cave. Radiocarbon dates show that fossils have been accumulating since at least 23,000 Y.B.P. It appears that wood rats and possibly small carnivores transported the fossils into the cave because only the smallest elements of large mammals are represented.

The fossil assemblage represents a much more boreal community than the present local fauna. …

Tradition And Individualism: Hans Banziger's Books On Swiss And German Literature, Marianne Burkhard

Swiss American Historical Society Newsletter

Over the years, I have seen Hans Banziger here and there, on both sides of the Atlantic. His slender figure would appear in the midst of people crowding lecture rooms at meetings of the Modern Language Association in New York or Chicago, his smile would suddenly greet me, in the summer, at the library in Zurich, and whenever possible he would attend the annual meeting of the Swiss American Historical Society, an intent listener often adding thoughtful comments or questions. Rather short in stature, his grey hair closely cropped, he has always been, for me, an example of the "Swiss" …

Statistical Assumption-Making In Library Collection Assessment: Peccadilloes And Pitfalls, Richard Hacken

Faculty Publications

Assessing library collections in the Semiconductor Age necessarily involves a heavy use of quantitative data. The assumptions made during the process of gathering, manipulating, and reporting library statistics may or may not be valid ones. Objective and vigilant scrutiny, therefore, can make the difference between an assessment that adds to a greater knowledge of the collection and one that only adds greater bulk to The File. Among the areas affected by statistical assumptions are (in lay terms): the sample, the survey, the percentage, the average, the degree of accuracy.

Effectiveness Of The Seed Wing Of Pinus Flexilis In Wind Dispersal, Ronald M. Lanner

Great Basin Naturalist

Limber pine (Pinus flexilis James) seeds are usually wingless but occasionally have short, stubby wings. To determine the effectiveness of these wings in slowing seed descent, rates of fall were determined before and after wing removal. A similar experiment was conducted with seeds of Himalayan blue pine (P. griffithii McClelland), a white pine with typically long seed wings. The short wings of limber pine seeds were found to influence rate of seed fall far less than the wings of Himalayan blue pine. This is consistent with evidence suggesting that limber pine seeds are not effectively dispersed by wind …

Size Selection Of Food By Cutthroat Trout, Salmo Clarki, In An Idaho Stream, William D. Skinner

Great Basin Naturalist

The mean size of food and amount of food consumed by cutthroat trout from Palisades Creek in southeastern Idaho increased with trout length. Number of organisms of terrestrial origin, number of aquatic larvae, number of ants, and number of berries from redstem dogwood were related to trout length. The size range and number of taxa consumed increased with trout size, indicating that as trout get larger, they broaden their feeding menu. The minimum size of food consumed was relatively constant for all trout, but larger trout appeared to feed more from the stream bottom. Trout may have a minimum length …

Flexible Engineering Software: An Integrated Workstation Approach To Finite Element Analysis, Brant Arnold Ross

Theses and Dissertations

One obstacle preventing more engineers from using finite element analysis (FEA) is the difficulty of transferring data between steps in the modeling process. A Fortran computer program, Rosetta.BYU, has been developed to open data paths between finite element preprocessors (mesh generators) and finite element analysis programs, using a custom data structure. It accepts neutral data files, Version 2.0 IGES data files, and Movie.BYU files for input/output. An application of Rosetta is described. A general workstation manager program, Davinci.BYU, is reviewed that provides a support layer between the engineer and the operating system, organizes software and data files, and facilitates on-line …

Food Of Cougars In The Cascade Range Of Oregon, Dale E. Toweill, Chris Maser

Great Basin Naturalist

Animal and nonanimal items were identified in the digestive tracts of 61 cougars (Felis concolor) collected between 1978 and 1984 from the western slopes of the Cascade Range in Oregon. Forty-two (69%) of the cougars were taken by hunters in December and January, 18 (30%) were killed at other times of the year because of their proximity to livestock, and one animal was illegally killed in November. Black-tailed deer (Odocoileus hemionus columbianus) was the most common prey item, although domestic sheep (Ovis airies), porcupines (Erethizon dorsatum), and a variety of small mammals …

Insect Communities And Faunas Of A Rocky Mountain Subalpine Sere, David J. Schimpf, James A. Macmahon

Great Basin Naturalist

Insect faunas and communities are characterized for herbaceous and tree canopy layers in meadow, aspen, and spruce/fir stages of a northern Utah sere. A greater percentage of species were in Thysanoptera in both aspen strata, and a greater percentage of individuals were in Lepidoptera in aspen canopy. Our sites were quite similar to a wide variety of other terrestrial sites in their distribution of species or individuals among orders or metamorphosis categories. Insects/m² peaked in the aspen stage, but declined in the herbaceous layer with succession. Insects/plant biomass in the herbaceous layer increased with succession. Insects/m² and insects/foliar …

Use Of Biomass Predicted By Regression From Cover Estimates To Compare Vegetational Similarity Of Sagebrush-Grass Sites, L. David Humphrey

Great Basin Naturalist

Regressions between vegetational cover, estimated with a two-tiered, gridded sampling frame, and biomass were used to obtain predicted biomass values from cover values. Comparisons of eight sites based on predicted biomass data and comparisons of the sites based on cover data indicate that predicted biomass data may better identify differences among sites. Also, some suggestions are made regarding the methods of using cover-biomass regressions to obtain predicted biomass values.

Spatial Patterns Of Plant Communities And Differential Weathering In Navajo National Monument, Arizona, Jack D. Brotherson, William E. Evenson, Samuel R. Rushforth, John Fairchild, Jeffrey R. Johansen

Great Basin Naturalist

Vegetation patterns in Navajo National Monument, Arizona, were studied over a five-year period from 1977 to 1981. Twelve distinct plant community types occur within the boundaries of the park. These communities are characterized and the dominant plant species of each are recorded. The relationships of parent material, soils, and moisture to plant communities are also discussed. It appears that discrete communities occupy soils of different characteristics, particularly with respect to amount of weathering of parent material.

Understory Response To Tree Harvesting Of Singleleaf Pinyon And Utah Juniper, Richard L. Everett, Steven H. Sharrow

Great Basin Naturalist

Fifteen widely separated sites within the pinyon-juniper woodlands of the Great Basin were cleared of trees. Understory response was recorded for 2 to 4 years. The array of postharvest plant assemblages were classified into one of four phytosociological groups using discriminant analysis. Pre- and postharvest plant assemblages from the same site appeared in the same phytosociological group, which indicates postharvest response could be predicted from the preharvest plant assemblage. Initial postharvest response appears cyclic in nature, and cycles are controlled by both residual plants and the rapid immigration of shrub species. Perennial plant density generally declined following tree harvest, but …

Great Black Goats And Evil Little Women: The Image Of The Witch In Sixteenth-Century German Aart, Jane P. Davidson

Quidditas

Witch imagery in German Renaissance art may strike the modern observer as something incongruous in an age noted for interest in humanism, reformation, science, appreciation of beauty and the like. Nonetheless, it existed. Further, we find a number of prominent German artists who depicted witches. The operative point here is probably an interest in realism. Renaissance artists, north and south, were preoccupied with reality. Too this end, their art stressed optical accuracy, factual anatomy, convincing natural details and so on.
