Taxonomy And Variation Of The Lopidea Nigridia Complex Of Western North America (Heteroptera: Miridae, Orthotylinae), Adam Asquith Jun 1990

Taxonomy And Variation Of The Lopidea Nigridia Complex Of Western North America (Heteroptera: Miridae, Orthotylinae), Adam Asquith

Great Basin Naturalist

External morphological variation in the Lopidea nigridia "complex" of western North America was examined using principal component analysis and showed continuous variation among populations in most characters. External morphology did not parallel paramere structure and did not substantiate previously recognized species. There was little correlation between dorsal coloration and paramere structure. Cluster analysis (UPGMA) using paramere and color characters failed to group populations coded as the same species and also failed to group all specimens of any one population. The variation in structure of the parameres and vesicae among populations of the nigridia complex was no greater than the interpopulational …

Effects Of Dwarf Mistletoe On Growth And Mortality Of Douglas-Fir In The Southwest, Robert L. Mathiasen, Frank G. Hawksworth, Carleton B. Edminster Jun 1990

Effects Of Dwarf Mistletoe On Growth And Mortality Of Douglas-Fir In The Southwest, Robert L. Mathiasen, Frank G. Hawksworth, Carleton B. Edminster

Great Basin Naturalist

The effects of dwarf mistletoe (Arceuthobium douglasii) on growth and mortality of Douglas-fir (Pseudotsuga menziesii) were studied on 387 plots in mixed-conifer stands in three national forests in New Mexico and two in Arizona. Analyses of 8,570 trees showed that low infection ratings (dwarf mistletoe classes 1 or 2) had no significant effect on tree growth, but that losses increased markedly as infection severity increased. Average volume growth losses for trees over 10 inches in diameter were: dwarf mistletoe class 3, 10%; class 4, 25%; class 5, 45%; and class 6, 65%. Mortality of Douglas-fir in …

Effects Of Nitrogen Availability On Growth And Photosynthesis Of Artemisia Tridentata Ssp. Wyomingensis, Paul S. Doescher, Richard F. Miller, Jianguo Wang, Jeff Rose Mar 1990

Effects Of Nitrogen Availability On Growth And Photosynthesis Of Artemisia Tridentata Ssp. Wyomingensis, Paul S. Doescher, Richard F. Miller, Jianguo Wang, Jeff Rose

Great Basin Naturalist

This study examined the effects of alterations in soil nitrogen on the growth of Artemessia tridentata ssp. wyomingensis Nutt. Soil nitrogen content was altered by applying sugar (45 g/m2), nitrate (4.5 g/m2), or ammonium (4.5 g/m2), and the results were compared with a control treatment (no soil amendments). Addition of either form of nitrogen significantly increased leaf nitrogen content, mean maximum length of ephemeral leaves, number of ephemeral leaves per terminal shoot, and current year's vegetative stem length over the control and sugar treatments. Both soil water and predawn xylem potentials during active growth …

Seed Production And Seedling Establishment Of A Southwest Riparian Tree, Arizona Walnut (Juglans Major), Juliet C. Stromberg, Duncan T. Patten Mar 1990

Seed Production And Seedling Establishment Of A Southwest Riparian Tree, Arizona Walnut (Juglans Major), Juliet C. Stromberg, Duncan T. Patten

Great Basin Naturalist

A four-year study of five populations has revealed influences on seed production and seedling establishment of the Southwest riparian tree Juglans major. Germination is abundant after production of large seed crops (masts), but masts are produced infrequently. Within years, germination is stimulated by summer rains, enabling seedlings to establish on riparian terraces as well as streambanks. Traits such as capacity for dormancy during summer drought allow some seedlings to survive on terraces, but abundant rainfall is essential for high rates of seedling success. Ranges of moisture tolerance vary among seeds collected from different populations, suggesting that ecotypes may exist …

Forage Quality Of Rillscale (Atriplex Suckleyi) Grown On Amended Bentonite Mine Spoil, Marguerite E. Voorhees Mar 1990

Forage Quality Of Rillscale (Atriplex Suckleyi) Grown On Amended Bentonite Mine Spoil, Marguerite E. Voorhees

Great Basin Naturalist

At peak standing crop, rillscale (Atriplex suckleyi) foliage grown on amended bentonite mine spoil contained adequate digestible energy, crude protein, and all mineral elements except phosphorus necessary for cattle, sheep, antelope, and deer. Amendments (sawdust, NPK, gypsum) generally did not affect forage quality. Iron, manganese, aluminum, sodium, and potassium concentrations were high and may have adversely affected forage quality. Forage utility would be limited to a few months during the growing season.

Summer Food Habits Of Coyotes In Idaho's River Of No Return Wilderness Area, Charles L. Elliott, Richard Guetig Mar 1990

Summer Food Habits Of Coyotes In Idaho's River Of No Return Wilderness Area, Charles L. Elliott, Richard Guetig

Great Basin Naturalist

Summer food habits of coyotes (Canis latrans)in the River of No Return Wilderness Area, Idaho, were determined. Analysis of 51 scats (fecal samples) revealed that Columbian ground squirrels (Spermophilus columbianus), mule deer (Odocoileus hemionus), and deer mice (Peromyscus manniculatus) exhibited the greatest frequency of occurrence for identified food items, being detected in 57%, 27%, and 16%, respectively, of scats examined.

Infection Of Young Douglas-Firs By Dwarf Mistletoe In The Southwest, Robert L. Mathiasen, Carleton B. Edminster, Frank G. Hawksworth Mar 1990

Infection Of Young Douglas-Firs By Dwarf Mistletoe In The Southwest, Robert L. Mathiasen, Carleton B. Edminster, Frank G. Hawksworth

Great Basin Naturalist

Studies in several areas in Arizona and New Mexico show that dwarf mistletoe (Arceuthobium douglasii) is rare in young Douglas-firs growing under infected overstories. Less than 5% of the Douglas-firs under 26 years old and less than 6% of those under 1.4m tall were infected in 77 mistletoe-infested stands. Both percent infection and mean dwarf mistletoe rating of young Douglas-firs increased as tree age, height, and stand dwarf mistletoe ratings increased.

Esox Lucius (Esocidae) And Stizostedion Vitreum (Percidae) In The Green River Basin, Colorado And Utah, Harold M. Tyus, James M. Beard Mar 1990

Esox Lucius (Esocidae) And Stizostedion Vitreum (Percidae) In The Green River Basin, Colorado And Utah, Harold M. Tyus, James M. Beard

Great Basin Naturalist

Northern pike, Esox lucius, stocked in the Yampa River in 1977, invaded the mainstream Green River by 1981 and subsequently increased in range and abundance. The speed of this invasion is indicated by two recaptured pike that moved 78 and 110 km, respectively, downstream in about one year. Pike stomachs (n = 123) were usually empty (54.5%), but some contained fish (43%) and nonfish items (2.4%). Red shiner, Notropis lutrensis, and fathead minnow, Pimephales promelas, predominated among the 12 fish species eaten. Walleye, Stizostedion vitreum, presumably introduced to the Green River drainage in the 1960s, was …

A Plasma Protein Marker For Population Genetic Studies Of The Desert Tortoise (Xerobates Agassizi), James L. Glenn, Richard C. Straight, Jack W. Sites Jr. Mar 1990

A Plasma Protein Marker For Population Genetic Studies Of The Desert Tortoise (Xerobates Agassizi), James L. Glenn, Richard C. Straight, Jack W. Sites Jr.

Great Basin Naturalist

Fifty-seven individual plasma samples from desert tortoises (Xerobates agassizi) representing 10 separate populations were analyzed by polyacrylamide gel electrophoresis using alkaline buffers. An albumin-like protein was found to be polymorphic for two electromorphs in northern populations inhabiting the Mohave Desert Province while Sonoran Desert populations to the south were monomorphic. The genetic divergence demonstrated in this survey is similar to earlier studies and provides evidence for the Colorado River as a potential barrier to gene flow among tortoise populations. These data suggest that tortoise plasma, examined by various electrophoretic methods, may provide a nondestructive means of determining the …

Niels E. Hansen: Plant Explorer, Harald Jensen Jan 1990

Niels E. Hansen: Plant Explorer, Harald Jensen

The Bridge

At the age of seventeen, Niels Ebbesen Hansen enrolled at Iowa State University, Ames, Iowa, where he met Professor J. L. Budd, head of the Department of Horticulture and a creative and inspiring person. This meeting with Professor Budd eventually caused young Hansen to major in horticulture, and plant exploration and development became his lifework. He graduated in 1887 from Iowa State and for the next four years worked in large commercial nurseries in Iowa. This experience, not only supplemented his previous theoretical training in college but gave him an invaluable insight into the problems of northwestern horticulture.

Symbolic Action And Persuasion In The Book Of Mormon, Keith H. Lane Jan 1990

Symbolic Action And Persuasion In The Book Of Mormon, Keith H. Lane

Theses and Dissertations

This thesis contends that the Book of Mormon can be profitably read from a rhetorical perspective. It employs Kenneth Burke's ideas concerning language, texts, and his method of dramatistic analysis, to reveal certain persuasive aspects of the Book of Mormon, and to urge action in response to the persuasion of the Book of Mormon.

Chapter one discusses common ways of reading scripture, and explains some of the inadequacies of these approaches. It gives a rationale of a rhetorical approach that concerns itself with action, and recommends this approach for the Book of Mormon. Chapter two applies a rhetorical reading to …

The Burden Of Responsibility In The Libro De Buen Amor, Lynn Williams Jan 1990

The Burden Of Responsibility In The Libro De Buen Amor, Lynn Williams

Faculty Publications

In three of the early sections of the Libro de buen amor, Juan Ruiz explains to his public how, for various reasons, he is conditioned to love women. In stanzas 71-76 he uses the unimpeachable authority of Aristotle to argue that men and animals are biologically determined to seek 'juntamiento con fenbra plazentera' (st. 71d), and since he is a man like any other, it is natural, perhaps even inevitable, that from time to time he too should feel the attraction of the opposite sex. Paraphrasing St Paul (I Thessalonians 5.21), the Archpriest tells us rather cheekily that one must …

He Sowed So That Others Could Reap: Niels Ebbesen Hansen 1866 -1950, J. Christian Bay

The Bridge

January 4 punctuates two events. On that date in 1851 type-setting began for the printing of a new novel, Uncle Tom's Cabin. On the same date in 1866 a boy was born on a farm near Ribe, Denmark, who in baptism in the cathedral was named Niels Ebbesen Hansen. The baptismal vessel used had passed from one generation to the next for over 200 years and had the ring of old Danish silver.

Age, Gender, And Religious Differences In Moral Perspective, Samuel L. Clay Jan 1990

Age, Gender, And Religious Differences In Moral Perspective, Samuel L. Clay

Theses and Dissertations

An investigation was conducted to see if age and gender are related to a preference for a caring versus a justice morality. The World View Questionnaire with 40 word pairs was used to measure a preference for a caring morality. It was found that there was a significant gender difference in the caring score, with the females scoring higher than the males. There also was a significant religious difference in the caring score with religious and especially Mormon subjects scoring higher than non-religious subjects. There was not, however, a significant age difference as was predicted.

Hyobranchial Apparatus Of The Cryptobranchoidea (Amphibia), Douglas C. Cox, Wilmer W. Tanner Oct 1989

Hyobranchial Apparatus Of The Cryptobranchoidea (Amphibia), Douglas C. Cox, Wilmer W. Tanner

Great Basin Naturalist

This report is a comparative study of the hyobranchial skeleton of the three species in the family Cyptobranchidae and four species of the family Hynobiidae, all of which are figured. Anatomical differences between the cryptobranchids and their relationship to hynobiids are noted and discussed. Reference is made to a relationship that may exist between these families and other salamander families, particularly the possible relationship of the Hynobiidae to the super families Ambystomatoidea or possibly Plethodontoidea.

On The Structure And Funtion Of White-Tailed Prairie Dog Burrows, James A. Burns, Dennis L. Flath, Tim W. Clark Oct 1989

On The Structure And Funtion Of White-Tailed Prairie Dog Burrows, James A. Burns, Dennis L. Flath, Tim W. Clark

Great Basin Naturalist

The architecture of burrows of the white-tailed prairie dog (Cynomys leucurus) is poorly known. For this reason and for comparative purposes, one recently active burrow of this species was excavated in southern Montana; the detailed methodology is described. Data were compiled on the dimensions of 29.3 m of excavated passages, and interpretations of several features are discussed. A "turning bay," sleeping quarters, two hibernacula, and a maternity area are described, the last feature for the first time in print. In addition, we report Cynomys using their teeth to dig, also for the first time. Further, an inadvertent remodeling …

Diet Similarity Between Elk And Deer In Utah, Kerry J. Mower, H. Duane Smith Oct 1989

Diet Similarity Between Elk And Deer In Utah, Kerry J. Mower, H. Duane Smith

Great Basin Naturalist

Growing numbers of elk (Cervus elaphus) on winter ranges might adversely affect sympatric wintering mule deer (Odoeoileus hemionus) if diets of the two species are similar. Diets of elk and deer on a northern Utah range were analyzed for overlap in winter with microhistological analysis of fecal samples. Diets overlapped 71%. No significant difference was found in use of grasses or shrubs between elk and deer; however, use of forbs was significantly different. Shrubs comprised the largest proportion of the diets of both elk and deer. Deer might be under more severe dietary stress than elk …

Arthropod Community Dynamics In Undisturbed And Intensively Managed Mountain Brush Habitats, Tim A. Christiansen, Jeffrey A. Lockwood, Jeff Powell Oct 1989

Arthropod Community Dynamics In Undisturbed And Intensively Managed Mountain Brush Habitats, Tim A. Christiansen, Jeffrey A. Lockwood, Jeff Powell

Great Basin Naturalist

The population dynamics of litter and foliage arthropods in undisturbed and intensively managed sagebrush (Artemisia tridentata) and bitterbrush (Purshia tridentata) habitats in southeastern Wyoming were assessed bv the measurement of density and the determination of indices of diversity, richness, and evenness. Brush management consisted of either mowing to a 20-cm stubble or applying the herbicide 2,4-D butyl ester. A total of 63 arthropod species were found in foliage and 150 species in litter. Mowing and herbicide applications resulted in significant changes in the density of 16 of the 46 major arthropod foliage species and 56 of …
