An Incentive-Based Wild Horse Management System On Public Rangeland, Ray G. Huffaker, James E. Wilen, B. Gardner Delworth Jan 1989

An Incentive-Based Wild Horse Management System On Public Rangeland, Ray G. Huffaker, James E. Wilen, B. Gardner Delworth

Faculty Publications

This paper explores an incentive-based management system to induce federal grazing permittees to choose sustained cattle stocking strategies which accommodate government-set wild horse numbers and nongrazing uses. Particular attention is paid to constraints imposed by federal grazing statutes. The proposed system employs increased livestock grazing fees to induce permittees to provide increased vegetation for consumption by wild horses and nongrazing uses. The negative impact of increased fees on permittee wealth is counterbalanced with compensatory transfer payments. Taken together, grazing fees and compensation payments induce multiple-use compliance by permittee-stewards and keep their discounted livestock profits intact at some predetermined level.

Food Habits Of Young-Of-Year Largemouth Bass In Lake Mead And Lake Mohave, Arizona–Nevada, Gene R. Wilde, Larry J. Paulson Oct 1988

Food Habits Of Young-Of-Year Largemouth Bass In Lake Mead And Lake Mohave, Arizona–Nevada, Gene R. Wilde, Larry J. Paulson

Great Basin Naturalist

Young-of-year largemouth bass from lakes Mead and Mohave fed upon crustacean zooplankton, insects (primarily chironomids), and fish. Largemouth bass smaller than 32 mm TL fed extensively upon zooplankton. In Lake Mead, transition to an insect-dominated diet occurred at 32 mm TL; transition to an insect-fish–dominated diet did not occur in Lake Mohave until a length of 56 mm was reached. Largemouth bass from Lake Mohave consumed significantly more zooplankton than did those from Lake Mead, but largemouth bass from Lake Mead consumed significantly more insects. Fish were most common in the diet of young-of-year largemouth bass larger than 52 mm …

A Mixed Pollination System In Penstemon Pseudospectabilis M. E. Jones (Scrophulariaceae), William H. Reid, Pamela Sensiba, C. Edward Freeman

Great Basin Naturalist

A population of Penstemon pseudospectabilis M. E. Jones (Scrophulariaceae) on Cave Creek in Cochise County, Arizona, was used in an experimental test of reproductive fitness with three caging treatments: all flying pollinators excluded, hummingbirds excluded, and no exclusion. Twenty plants were chosen and three shoots on each used in the experiment. The flowers were 25.6 (s.d. = 1.5) mm long, the end diameter was 8.5 (s.d. = 1.0) mm, the tube opening was 6.5 (s.d. = 1.0) mm, and the greatest diameter, 75% distal from the receptacle, was 10.1 (s.d. = 0.8) mm (N= 59). Floral nectar contained 11.7% (s.d. …

Spring Denitrification Rates In Soils Of Four Eastside Sierra Nevada Plant Communities, S. E. Hixson, R. F. Walker, C. M. Skau Oct 1988

Spring Denitrification Rates In Soils Of Four Eastside Sierra Nevada Plant Communities, S. E. Hixson, R. F. Walker, C. M. Skau

Great Basin Naturalist

Denitrification rates in soils of four subalpine plant communities in the Sierra Nevada were determined by the acetylene blockage method. The study area included riparian, meadow, forest, and barren sites. Data were collected during dawn-to-dusk measurements in April 1987. Soil atmosphere samples were analyzed for N2O content using gas chromatography. Generally, temporal variability in denitrification rate within each plant community was insubstantial. Denitrification rate and soil temperature were found to be significantly correlated only in the riparian and barren sites. Of the four communities, the riparian site was found to have the lowest rate of denitrification overall. However, …

Evidence For An Indo-Pacific Origin Of Hawaiian Endemics In Balclutha And Related Genera (Cicadellidae: Macrostelini), W. J. Knight, M. D. Webb Oct 1988

Evidence For An Indo-Pacific Origin Of Hawaiian Endemics In Balclutha And Related Genera (Cicadellidae: Macrostelini), W. J. Knight, M. D. Webb

Great Basin Naturalist Memoirs

The 10 endemic species of Balclutha in Hawaii are reviewed and compared with the Pacific and American forms of the genus. Two new species, nigriventris and fuscifrons, are described; kilaueae is transferred to a new genus Balolina n. comb.; beardsleyi is synonymized with saltuella, n. syn.; and hospes is relegated to a subspecies of incisa, n. stat. Descriptions and notes, together with illustrations and a key, are given for each taxon. Evidence is presented to suggest that all the endemic species of Balclutha have arisen within the islands from a single colonization and that the taxon showing …

Genus Flexamia: New Species, Phylogeny, And Ecology, Robert F. Whitcomb, Andrew L. Hicks Oct 1988

Genus Flexamia: New Species, Phylogeny, And Ecology, Robert F. Whitcomb, Andrew L. Hicks

Great Basin Naturalist Memoirs

Eight new species of Flexamia DeLong are described, and two Mexican species previously synonymized are reinstated. Species are assigned to 13 species groups; keys are presented for the groups and for the 44 recognized species. Host data, in many cases with oligophagy coefficients, are presented for 37 of the species. Many species specialize on native, dominant, perennial, choridoid or panicoid grasses; some are monophagous. Seven sister species pairs specialize on the same (or a closely related) grass species; in addition, four closely related species appear to be restricted to Bouteloua curtipendula. Few if any specialists colonize their host throughout …

Some Aspects Of The Biology, Morphology, And Evolution Of Leafhoppers (Homoptera: Cicadelloidea And Membracoidea), J. W. Evans Oct 1988

Some Aspects Of The Biology, Morphology, And Evolution Of Leafhoppers (Homoptera: Cicadelloidea And Membracoidea), J. W. Evans

Great Basin Naturalist Memoirs

This article summarizes some observations of a varied nature on the biology, morphology, and evolution of the Cicadelloidea (Cicadellidae, Hylicidae, Eurymelidae) and Membraciodea ( Membracidae, Aetalionidae, Biturritidae, Nicomiidae). These observations, made over a period of more than half a century, have previously been recorded at different times, but lie buried in the literature. It is hoped that their interest will justify repitition and draw attention to some promising lines of research.

A Numerical Taxonomic Analysis Of Interspecific Morphological Differences In Two Closely Related Species Of Cicada (Homoptera, Cicadidae) In Portugal, J. A. Quartau Oct 1988

A Numerical Taxonomic Analysis Of Interspecific Morphological Differences In Two Closely Related Species Of Cicada (Homoptera, Cicadidae) In Portugal, J. A. Quartau

Great Basin Naturalist Memoirs

Cicada orni Linnaeus is among the most common and widespread cicadas in Portugal, and, unless a critical study of the male genitalia is made, it is easily confused with the much less widely distributed C. Barbara lusitanica Boulard. These species are morphologically very similar and sometimes difficult to separate using existing keys. This study attempts to test the discriminating capabilities of numerical techniques commonly used for classificatory purposes, as well as to discover the most effective characters to distinguish between the two species. For these purposes, cluster analysis and principal component analysis were applied to a sample of 64 male …

Interactions Among Squirrels, Mycorrhizal Fungi, And Coniferous Forests In Oregon, Chris Maser, Zane Maser Jul 1988

Interactions Among Squirrels, Mycorrhizal Fungi, And Coniferous Forests In Oregon, Chris Maser, Zane Maser

Great Basin Naturalist

We examined the mycophagy (ingestion of fungi) of squirrels of five genera and eight species in the coniferous forests of Oregon. Data from 644 dietary samples demonstrated that squirrels of all eight species are mycophagous and eat the belowground fruiting bodies of at least 26 genera of mycorrhizal fungi. Four species are primarily arboreal and active throughout the year; the other four are primarily terrestrial and hibernate during winter. Of the squirrels examined, only the northern flying squirrel (Glaucomys sabrinus [Shaw]) is nocturnal and almost exclusively a fungivore. The flying squirrel is used to illustrate the dynamics of all …

Waterfowl And Shorebird Use Of Surface-Mined And Livestock Water Impoundments On The Northern Great Plains, Daniel W. Uresk, Kieth Severson Jul 1988

Waterfowl And Shorebird Use Of Surface-Mined And Livestock Water Impoundments On The Northern Great Plains, Daniel W. Uresk, Kieth Severson

Great Basin Naturalist

Cluster analysis and stepwise discriminant analysis were used to group waterfowl and shorebird use on water impoundments (bentonite, coal, livestock) on the Northern High Plains. Three bird-use categories—high, medium, and low—were delineated by these analytical procedures. Eleven physical, chemical, and biological parameters of impoundments were related to bird use; water area, nitrogen, and low basin slopes were found to be important parameters in estimating bird use on impoundments. Spring and summer were the best seasons for surveying waterfowl and shorebird water impoundment use.

Computer Analysis Of Cross Sections Of Leaves Of Chrysothamnus Taxa And Their Relation To Environmental Conditions, J. Huang, W. M. Hess, D. J. Weber, E. D. Mcarthur, S. E. Meyer, R. Seegmiller Jul 1988

Computer Analysis Of Cross Sections Of Leaves Of Chrysothamnus Taxa And Their Relation To Environmental Conditions, J. Huang, W. M. Hess, D. J. Weber, E. D. Mcarthur, S. E. Meyer, R. Seegmiller

Great Basin Naturalist

Thirty-eight accessions of 20 taxa (species and subspecies) of Chrysothamnus from a range of environments were grown in a uniform garden. During mid-June, terminal and lateral leaves were removed, fixed, and processed for light-microscopy studies. Area and perimeter measurements of ink tracings of midleaf vein cross sections were measured using computer-scan techniques. Leaf area and perimeter were compared with vein perimeter and area measurements. Area and perimeter of these Chrysothamnus leaves varied in response to the environment at the collection location. Plants native to hot, dry conditions had small, thick leaves, whereas plants native to cooler, more mesic conditions had …

Studies Of A Uniparental Form Of Aphytis Vandenboschi (Hymenoptera: Aphelinidae), A Parasite Of The San Jose Scale In Northern Utah, Manas Titayavan, Donald W. Davis Jul 1988

Studies Of A Uniparental Form Of Aphytis Vandenboschi (Hymenoptera: Aphelinidae), A Parasite Of The San Jose Scale In Northern Utah, Manas Titayavan, Donald W. Davis

Great Basin Naturalist

The only San Jose scale parasite found at two sites in northern Utah was a uniparental form of Aphytis vandenboschi DeBach & Rosen. Parasites overwintered as pupae and were attracted to San Jose scale pheromone traps. Mature female scales were most heavily parasitized, although some prepupal males and instar II female scales were attacked. Only partial development occurred between 11.7 and 18.3 C, and fecundity was reduced between 28 and 31 C. Based on 11.7 C, 460 degree days were required in the field and 410 degree days at 26 C in the laboratory per generation. By the end of …

Douglas-Fir Beetle (Dendroctonus Pseudotsugae Hopkins, Coleoptera: Scolytidae) Brood Production On Douglas-Fir Defoliated By Western Spruce Budworm (Choristoneura Occidentalis Freeman, Lepidoptera: Tortricidae) In Logan Canyon, Utah, S. E. Fredericks, M. J. Jenkins

Great Basin Naturalist

Douglas-fir beetle brood production was studied on Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco) trees defoliated by the western spruce budworm between 1983 and 1985. Tallies were made of the number of attacks, total length and number of egg galleries, number of eggs deposited, number of larval tunnels, number of pupal chambers, and number of emerging beetles (per female and per unit area). Data analysis showed no significant differences among the three years studied. The number of emerging beetles per female parent was 0.59, and emergence per 90 cm2 was 2.32 beetles. Egg, larval, and pupal survivals were 47.5%, 30.0%, …
