Factors Influencing Fish Assemblages Of A High-Elevation Desert Stream System In Wyoming, Bernard Carter, Wayne A. Hubert

Great Basin Naturalist

Seven fish species were found in the Bitter Creek drainage of southwest Wyoming, but only speckled dace (Rhinichthys osculus), flannelmouth sucker (Catostomus latipinnis), and mountain sucker (Catostomus platyrhynchus) were indigenous. No relationships were found between fish standing stocks and habitat features, but species richness was related to elevation and stream width. No fish were found above an elevation of 2192 m. Only the most downstream study reach had more than three species present. Two indigenous species, speckled dace and mountain sucker, and a nonnative species, fathead minnow (Pimephales promelas), were predominant fishes …

Invertebrate Fauna Of Wastewater Ponds In Southeastern Idaho, Karen L. Cieminski, Lester D. Flake

Great Basin Naturalist

Water column invertebrates were sampled with 3.8-L activity traps in 15 sewage, industrial, and radioactive wastewater ponds at the Idaho National Engineering Laboratory in southeastern Idaho. One collection was made per pond, per month, during all months the ponds were ice-free from June 1990 through July 1991. Arsenic, barium, boron, lead, selenium, and mercury were detected in ponds. Sewage ponds generally had higher nitrogen and phosphorus levels than industrial and radioactive ponds. Of the 30 aquatic invertebrate taxa collected, the most ubiquitous were Rotifera, Daphnidea, Eucopepdoa, Ostracoda, Acari, Baetidae, Corixidae, Notonectidiae, Dytiscidae, and Chironomidae. Activity trap samples from sewage ponds …

Douglas-Fir Tussock Moth (Orgyia Pseudotsugata Mcdunnough) On Subalpine Fir In Northern Utah, E. Matthew Hansen

Great Basin Naturalist

Douglas-fir tussock moth (Orgyia pseudotsugata McDunnough) defoliation was detected by aerial survey on three areas of the Wasatch-Cache National Forest in 1990 and 1991. These are the first documented tussock moth outbreaks in Utah. Ground surveys revealed that subalpine fir (Abies lasiocarpa [Hook.] Nutt.) was heavily defoliated during the outbreak. Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco), though minor component in the affected areas, had noticeably less defoliation and mortality. Adjacent stands of Douglas-fir had little or no visible tussock moth activity. Defoliation on subalpine fir was typically found evenly distributed throughout the crown rather than concentrated at the …

Carbon Isotope Discrimination In The C4 Shrub Atriplex Confertifolia Along A Salinity Gradient, Darren R. Sandquist, James R. Ehleringer

Great Basin Naturalist

Carbon isotope discrimination (∆) was measured for leaves of Atriplex confertifolia along a salinity gradient in northern Utah. Over this gradient, the variation of ∆ values was high for a C₄ species, and the ∆ values were positively correlated with salinity in both years of study. Of the possible explanations for this pattern, the ∆ results are consistent with the notion that salinity induces an increase in the bundle sheath leakiness of these C₄ plants.

Calileuctra, A New Genus, And Two New Species Of Stoneflies From California (Plecoptera: Leuctridae), W. D. Shepard, Richard W. Baumann

Great Basin Naturalist

Calileuctra is proposed as new genus in the family Leuctridae, with Calileuctra ephemera designated as the type species. All stages of Calileuctra ephemera are described. Calileuctra dobryi is described in the male and female stages. Both species inhabit the Mediterranean climatic region of California. A phylogenetic analysis of the genera in the family Leuctridae is given, which places Calileuctra near the genus of Perlomyia.

Growth And Reproduction In An Alpine Cushion Plant: Astragalus Kentrophyta Var. Implexus, Wayne R. Owen

Great Basin Naturalist

A two-year field experiment was conducted to investigate factors hypothesized to affect the reproductive potential of Astragalus kentrophyta var. implexus and to test the importance of trade-offs between growth and reproduction in this species. Levels of mineral nutrients, water, herbivory, and competition were manipulated. Seed output and growth of individuals in treatment groups were compared against control plants. Neither water nor mineral nutrients alone were shown to affect growth or reproduction. Herbivory was shown to be similarly unimportant in affecting growth and reproduction. Competition with other species influenced growth but not reproduction. No significant trade-offs between growth and reproduction were …

Demography Of Astragalus Scaphoides And Effects Of Herbivory On Population Growth, Peter Lesica

Great Basin Naturalist

Losses in fecundity due to predispersal herbivory can be large; however, the effects of this loss on long-term population viability have rarely been investigated. I conducted a demographic study of Astragalus scaphoides (Fabaceae), a long-lived perennial endemic to east central Idaho and adjacent Montana, by following mapped individuals at two sites from 1986 to 1993. Astragalus scaphoides suffers losses of predispersal fecundity averaging nearly 50% from insect seed predation and inflorescence predation by insects and livestock. Cattle reduced fecundity by 0–85%. Nonetheless, estimates from matrix projection models indicate that both sample populations had positive growth in most years. Elasticity analyses …

Lahontan Sagebrush (Artemisia Arbuscula Ssp. Longicaulis): A New Taxon, Alma H. Winward, E. Durant Mcarthur

Great Basin Naturalist

A new subspecies of Artemisia arbuscula is described, A. arbuscula ssp. longicaulis Winward & McArthur, ssp. nov. This taxon is a landscape dominant in portions of northwestern Nevada and adjacent California and Oregon at elevations from 1050 to 2000 m on shallow or argillic (clayey) soils. It differs from A. arbuscula ssp. arbuscula in its long floral stalks and large leaves. Morphological, chemical, ecological, and cytological data suggest that it is of hybrid origin. It is hexaploid (6x). We hypothesize that 2x A. arbusucla ssp. arbusucla and 4x A. tridentata ssp. wyomingensis are its parents.

Diets Of Young Colorado Squawfish And Other Small Fish In Backwaters Of The Green River, Colorado And Utah, Robert T. Muth, Darrel E. Snyder

Great Basin Naturalist

We compared diet of young-of-year Colorado squawfish (Ptychocheilus lucius), an endangered cyprinid, with diets of other fish < 75 mm total length (TL) collected from backwaters of the Green River between river kilometers 555 and 35 during summer and autumn 1987. Species included native Rhinichthys osculus, Catostomus discobolus, and C. latipinnts, and nonnative Cyprinella lutrensis, Notropis stramineus, Pimephales promelas, Ictalurus punctatus, and Lepomis cyanellus. For each species, diet varied with size and between upper and lower river reaches but not between seasons for fish of similar size. Larval chironomids and ccratopogonids were principal foods of most fishes. Copepods and cladocerans were important in diets of P. lucius < 21 mm TL and L. cyanellus < 31 mm TL. Catostomus discobolus was the only species that ate moderate amounts of algae. Fish (all larvae) …

The Book Of Mormon As Translation English, Sidney B. Sperry

Journal of Book of Mormon Studies

The Book of Mormon is a translation, containing details of the original language in which it is written. Very few of the writers would have had a working knowledge of Egyptian; the writing would more likely be a Hebraized Egyptian. The Book of Mormon contains many passages from Isaiah, more correctly translated than in the King James Version. Various examples of the Hebrew construct state are evident in Joseph Smith’s translation, together with direct translations of Hebrew idioms.

Factors Affecting Selection Of Winter Food And Roosting Resources By Porcupines In Utah, Dave Stricklan, Jerran T. Flinders, Rex G. Cates

Great Basin Naturalist

Ecological and phytochemical factors potentially affecting winter dietary discrimination by porcupines (Erethizon dorsatum) in the mountain brush zone of Utah were studied. Porcupines utilized gambel oak (Quercus gambelii) as their primary winter food and roosting resource. Big-tooth maple (Acer grandidentatum) was the most common tree species in the study area but was rarely utilized by porcupines. Conifer species were used as a food and roosting resource significantly less often than they occurred in the study area, despite thermal advantages provided by their relatively dense canopies. Oak feed trees were successfully separated from conifer feed …

Whipworm (Trichuris Dipodomys) Infection In Kangaroo Rats (Dipodomys Spp.): Effects On Digestive Efficiency, James C. Munger, Todd A. Slichter

Great Basin Naturalist

To determine whether infections by whipworms (Trichuris dipodomys [Nematoda: Trichurata: Trichuridae]) might affect digestive efficiency and therefore energy budgets of two species of kangaroo rats (Dipodomys microps and Dipodomys ordii [Rodentia: Heteromyidae]), we compared the apparent dry matter digestibility of tree groups of hosts: those naturally infected with whipworms, those naturally uninfected with whipworm, and those originally naturally infected but later deinfected by treatment with the anthelminthic Ivermectin. Prevalence of T. dipodomys was higher in D. microps (53%) than in D. ordii (14%). Apparent dry matter digestibility was reduced by whipworm infection in D. microps but not in …

Rangeland Alpha Diversities: Harvey Valley, Lassen National Forest, California, Raymond D. Ratliff

Great Basin Naturalist

Monitoring diversity usually begins by estimating alpha diversity of a plant community on a specific site. The objectives of this study were to provide alpha diversity benchmarks and to determine whether rangeland community basal cover characteristics explained variation in diversity estimates. Plant and surface component cover percentages were estimated on 51 plots (representing four vegetation types) on the Lassen National Forest, CA. Each plot was sampled with 30 random, 102 basal point transects. Jackknife procedures were used to compute means and standard errors for Margalef's diversity index (D_m), which stresses species richness, and Simpson's index (D_s), …

Pollinator Sharing By Three Sympatric Milkvetches, Including The Endangered Species Astragalus Montii, S. M. Geer, V. J. Tepedino, T. L. Griswold, W. R. Bowlin

Great Basin Naturalist

Insects visiting flowers of the endangered Heliotrope milkvetch, Astragalus montii, were compared with those visiting two common sympatric congeners, A. kentrophyta and A. miser, on three sites on the Wasatch Plateau of central Utah for 2 yr. We recorded 27+ species of bees, most of which were uncommon, visiting the three species. All three species were primarily visited by native bees of the genera Osmia (15 species) and/or Bombus (4 species). Most Osmia species visited the three species of Astragalus indiscriminantly; bumblebees preferred A. miser and avoided A. montii. Our hypothesis that A. montii flowers would receive …
