Spotted Knapweed Distribution In Stock Camps And Trails Of The Selway-Bitterroot Wilderness, W. Andrew Marcus, Gary Milner, Bruce Maxwell Apr 1998

Spotted Knapweed Distribution In Stock Camps And Trails Of The Selway-Bitterroot Wilderness, W. Andrew Marcus, Gary Milner, Bruce Maxwell

Great Basin Naturalist

This article documents spotted knapweed (Centaurea maculosa Lam.) in 30 campsites and along 5 trails in the Selway-Bitterroot Wilderness and assesses the role of disturbance and environmental factors in controlling infestation. Spotted knapweed was present in only 6 of 30 surveyed campsites and limited portions of all 5 trails that were sampled. All spotted knapweed in camps was below 1700 m elevation, in open canopy, and in areas with an opportunity class disturbance ranking of 3 or 4. Overall disturbance levels measured using U.S. Forest Service Site Impact Worksheets (SIWs) did not help predict occurrence of spotted knapweed, although …

Vegetal Change On A Northern Utah Foothill Range In The Absence Of Livestock Grazing Between 1948 And 1982, Dennis D. Austin, Philip J. Urness Apr 1998

Vegetal Change On A Northern Utah Foothill Range In The Absence Of Livestock Grazing Between 1948 And 1982, Dennis D. Austin, Philip J. Urness

Great Basin Naturalist

Reexamination of a semiarid foothill rangeland, first evaluated in 1948, indicated that secondary succession continues to shift toward a perennial grass-forb community formerly dominated by xeric shrubs, particularly big sagebrush (Artemisia tridentata spp. vaseyana). The direct role in livestock grazing in establishment and maintenance of shrub-dominant plant communities appears confirmed in the decline of shrubs upon cessation of livestock grazing in summer and continued browsing by mule deer in winter. The reduction of shrub forages on mule deer winter ranges is a major factor in population declines.


Breeding Birds At The Idaho National Engineering And Environmental Laboratory, 1985–1991, James R. Belthoff, Leon R. Powers, Timothy D. Reynolds Apr 1998

Breeding Birds At The Idaho National Engineering And Environmental Laboratory, 1985–1991, James R. Belthoff, Leon R. Powers, Timothy D. Reynolds

Great Basin Naturalist

During the summers of 1985–1991, bird censuses were conducted along 13 permanent routes located at the 2315-km2 Idaho National Engineering and Environmental Laboratory (INEEL, formerly INEL) in southeastern Idaho. The objectives of the surveys were to (1) compare avifauna in and near facility complex sites with remote, relatively undisturbed habitats, (2) identify trends in populations of sagebrush-obligate species and other common shrub-steppe species, and (3) determine the presence, abundance, and population status of species of special concern. Five routes were official U.S. Geological Survey, Biological Resources Division 40.0-km Breeding Bird Survey (BBS) routes (formerly administered by the U.S. Fish …


Chironomidae (Diptera) Of The Colorado River, Grand Canyon, Arizona, Usa, Ii: Factors Influencing Distribution, Lawrence E. Stevens, James E. Sublette, Joseph P. Shannon Apr 1998

Chironomidae (Diptera) Of The Colorado River, Grand Canyon, Arizona, Usa, Ii: Factors Influencing Distribution, Lawrence E. Stevens, James E. Sublette, Joseph P. Shannon

Great Basin Naturalist

Biogeographic, flow regulation (water clarity and temperature), and temporal influences affect the composition of the chironomid midge assemblage in the Colorado River between Glen Canyon Dam and Lake Mead. This assemblage is dominated by euryecious Nearctic and Holarctic orthocladine taxa (23 of 38 total species, total weighted relative abundance [WRA] = 0.972) and includes a minor Neotropical component. Chironomid species richness increases over distance downstream from the dam, and dominance shifts across 3 turbidity segments. Eleven species occur in the cold-stenothermic Clearwater (CW) segment between the dam and the 1st perennial tributary (the Paria River, 26 km from the dam). …


Spiritual Issues And Interventions In The Treatment Of Patients With Eating Disorders, P. Scott Richards, Randy K. Hardman, Harold A. Frost, Michael E. Berrett Apr 1998

Spiritual Issues And Interventions In The Treatment Of Patients With Eating Disorders, P. Scott Richards, Randy K. Hardman, Harold A. Frost, Michael E. Berrett

Issues in Religion and Psychotherapy

This article examines the roles of religion and spirituality in the etiology and treatment of eating disorders. After briefly reviewing the relevant research, we discuss the most common and significant religious and spiritual issues wer have observed with LDS eating disorder patients including negative images or perceptions of God, feelings of spiritual unworthiness and shame, and fear of abandonment by God. We briefly describe process considerations for using spiritual interventions and concluded by describing seven spiritual interventions we have found especially useful in treating LDS eating disorder patients, including spiritual teachings, spiritual bibliotherapy, and prayer.

"Can I Feel Better Even If I Can't Remember?" Helping Clients With Incomplete Memories, Marleen S. Williams Apr 1998

"Can I Feel Better Even If I Can't Remember?" Helping Clients With Incomplete Memories, Marleen S. Williams

Issues in Religion and Psychotherapy

Clients may request therapy for symptoms that resemble those for sexual abuse survivors, although they have sketchy or no memories for abuse. "Recovered memory" therapy has been the subject of considerable controversy and legal debate. There are still many other options for treating the clients distress without using "memory recovery" techniques. Goals, skills, and techniques for working with these clients are presented here.


Bringing To Remembrance: The Trauma Memory Debate, Marleen S. Williams Apr 1998

Bringing To Remembrance: The Trauma Memory Debate, Marleen S. Williams

Issues in Religion and Psychotherapy

Recent focus on memories of abuse that are recalled during therapy has alerted mental health care providers to potential hazards to the client, the therapist, and innocent others. Being aware of current research on how memory works can help reduce these risks. Integrating information from both sides of the debate provides a more accurate understanding of delayed memory recall.

Determination Of The Asymmetry Parameter And Scattering Coefficient Of Turbid Media From Spatially Resolved Reflectance Measurments, Matthew R. Jones, Yukio Yamada Mar 1998

Determination Of The Asymmetry Parameter And Scattering Coefficient Of Turbid Media From Spatially Resolved Reflectance Measurments, Matthew R. Jones, Yukio Yamada

Faculty Publications

We present a technique for determining the asymmetry parameter and scattering coefficient of turbid media from spatially resolved reflectance measurements. This technique will contribute to the development of medical applications in which it is necessary to predict the distribution and propagation of light in tissue. Based on Monte Carlo simulations, we derived correlations which relate the reduced scattering coefficient and the asymmetry parameter to the relative reflectance curve. Initial estimates of the optical properties are obtained from these correlations. Final values are obtained by adjusting the optical parameters and repeating the Monte Carlo simulations until the simulated reflectance pattern matches …


Understanding Comics: The Invisible Art, Alan D. Manning Mar 1998

Understanding Comics: The Invisible Art, Alan D. Manning

Faculty Publications

INSIGHTS about professional communication may come from odd and unexpected places. McCloud's Understanding Comics (hereafter UC) is a case in point. Despite the juvenile connotations evoked by any discussion of comic books, the theory of visual communication presented in UC arguably rivals the best of contemporary semiotics (that is, the study of how we make meaning out of gestures, words, paragraphs, pictures, and so on).


Randomly Amplified Polymorphic Dna Analysis (Rapd) Of Artemisia Subgenus Tridentatae Species And Hybrids, E. Durant Mcarthur, Joann Mudge, Renée Van Buren, W. Ralph Andersen, Stewart C. Sanderson, David G. Babbel Jan 1998

Randomly Amplified Polymorphic Dna Analysis (Rapd) Of Artemisia Subgenus Tridentatae Species And Hybrids, E. Durant Mcarthur, Joann Mudge, Renée Van Buren, W. Ralph Andersen, Stewart C. Sanderson, David G. Babbel

Great Basin Naturalist

Species of Artemisia (subgenus Tridentatae) dominate much of western North America. The genetic variation that allows this broad ecological adaptation is facilitated by hybridization and polyploidization. Three separate studies were performed in this group using randomly amplified polymorphic DNA (RAPD). Fifty-seven 10-mer primers generated nearly 400 markers from genomic DNA obtained from leaf tissue. These studies were (1) a measure of the variability of plants within and between populations and between subspecies using 5 A. tridentata ssp. wyomingensis populations, 2 A. cana ssp. cana populations, and 1 A. cana ssp. viscidula population; (2) an examination of the hypothesis that …

Habitat Use By Small Mammals In Southeastern Utah, With Reference To Mexican Spotted Owl Management, Maite Sureda, Michael L. Morrison Jan 1998

Habitat Use By Small Mammals In Southeastern Utah, With Reference To Mexican Spotted Owl Management, Maite Sureda, Michael L. Morrison

Great Basin Naturalist

We determined temporal and spatial differences in abundance and habitat use by small mammals in southeastern Utah as part of an effort to enhance management of the Mexican Spotted Owl (Strix occidentalis lucida), listed by the federal government as threatened. Woodrats (Neotoma spp.) were captured only in canyons and most frequently in the pinyon-juniper (Pinus edulis–Juniperus osteosperma) vegetation type. White-footed mice (Peromyscus spp.) were found in a variety of vegetation types in both canyons and mesas. The deer mouse (P. maniculatus) was generally the most frequently captured species among vegetation types. We …


Identity Of Mertensia Oblongifolia (Nutt.) G. Don (Boraginaceae) And Its Allies In Western North America, Ahmed M. Warfa Jan 1998

Identity Of Mertensia Oblongifolia (Nutt.) G. Don (Boraginaceae) And Its Allies In Western North America, Ahmed M. Warfa

Great Basin Naturalist

The current status of Mertensia oblongifolia (Nutt.) G. Don and its allied taxa is surveyed. On the bases of continuously coherent morphological characters and/or regionally correlated variations, more than 30 taxa, including species, subspecies, varieties, and 1 forma, previously considered different from M. oblongifolia, are now placed under synonymy of this species. Those taxa currently known as M. fusiformis Greene, M. bakeri Greene, and M. bakeri var. osterhoutii Williams are among the new synonyms. Typification, taxonomy, and morphological problems of M. oblongifolia are discussed.

Late Pleistocene Microtine Rodents From Snake Creek Burial Cave, White Pine County, Nevada, Christopher J. Bell, Jim I. Mead Jan 1998

Late Pleistocene Microtine Rodents From Snake Creek Burial Cave, White Pine County, Nevada, Christopher J. Bell, Jim I. Mead

Great Basin Naturalist

A total of 395 microtine rodent specimens recovered from Snake Creek Burial Cave (SCBC) are referred to Microtus sp. and Lemmiscus curtatus. Radiocarbon and Uranium series dates indicated an age for these fossils of between 9460 ± 160 yr. B.P. and 15,100 ± 700 yr. B.P. The sample of lower first molars of Lemmiscus includes 4-, 5-, and 6-closed triangle morphotypes. Earlier reports of the 4-closed triangle morphotype are from Irvingtonian deposits in Colorado, Nevada, and New Mexico and from early Rancholabrean deposits in Washington. The morphotype is not known in living populations of Lemmiscus. SCBC specimens constitute …

Taxonomy Of Sphaeromeria, Artemisia, And Tanacetum (Compositae, Anthemideae) Based On Randomly Amplified Polymorphic Dna (Rapd), E. Durant Mcarthur, Renée Van Buren, Stewart C. Sanderson, Kimball T. Harper

Great Basin Naturalist

Relationships within, between, and among the Anthemideae genera Sphaeromeria, Artemisia, and Tanacetum were investigated using 238 randomly amplified polymorphic DNA (RAPD) markers obtained from twenty 10-mer primers amplified on genomic DNA. Forty-one populations from 16 taxa (15 species) were studied. Jaccard's coefficient of similarity and UPGMA clustering analysis were used to construct phenograms. T tests were used to make comparisons between samples at various systematic levels. DNA markers were 75% similar for conspecific populations. Sixteen Sphaeromeria populations (5 species) showed an average interspecific similarity of 21%. Interspecific similarity among 23 Artemisia populations (8 species with 2 subspecies of A. …

Regional Assessment Of Wadable Streams In Idaho, Usa, Christopher T. Robinson, G. Wayne Minshall Jan 1998

Regional Assessment Of Wadable Streams In Idaho, Usa, Christopher T. Robinson, G. Wayne Minshall

Great Basin Naturalist

There has been a resurgence in applying bioassessment techniques for evaluating and monitoring the biological integrity of stream ecosystems. In all cases biological metrics have been refined to account for regional variation in aquatic habitats and fauna. This study evaluated environmental and macroinvertebrate properties for wadable streams in 3 major ecoregions of Idaho: Northern Basin and Range, Snake River Plain, and Northern Rocky Mountain. These 3 ecoregions constitute > 80% of the land area in Idaho. Reference streams were delineated from test streams in each ecoregion using standard habitat assessment protocols (Plafkin et al. 1989). Multiple discriminant analysis effectively determined habitat …
