Burrows Of The Sagebrush Vole (Lemmiscus Curtatus) In Southeastern Idaho, Tim R. Mullican, Barry L. Keller Apr 1987

Burrows Of The Sagebrush Vole (Lemmiscus Curtatus) In Southeastern Idaho, Tim R. Mullican, Barry L. Keller

Great Basin Naturalist

Burrows of the sagebrush vole (Lemmiscus curtatus) were analyzed by injecting them with expanding polyurethane foam. Average mean depth ± 1 SE of four burrows was 12.5 ± 2.6 cm. Tunnels were wider than high and flat on the bottom. Three of four burrows were nearly linear, with an average of five entrances. Burrows usually contained one nest made of Artemisia tridentata bark. No middens or communal nests were found. The burrow structure in sagebrush habitat suggests that sagebrush voles occur singly or in pairs rather than in colonies.

Flora Of The Orange Cliffs Of Utah, L. M. Shultz, E. E. Neely, J. S. Tuhy Apr 1987

Flora Of The Orange Cliffs Of Utah, L. M. Shultz, E. E. Neely, J. S. Tuhy

Great Basin Naturalist

The vascular flora of the Orange Cliffs area, defined here as part of the Colorado Plateau floristic province, harbors approximately 209 species in 123 genera and 49 families. A species checklist is provided with a discussion of physical and floristic aspects of the region. The flora is compared statistically to the San Rafael Swell flora, which is also a subset of the Colorado Plateau. We define six vegetation types and three edaphic communities; these are described and mapped. Of eleven endemic plant species in the Orange Cliffs, three are local and rare. Sites for Astragalus nidularius, A. moencoppensis, and Xylorhiza …


Plant Community Zonation In Response To Soil Gradients In A Saline Meadow Near Utah Lake, Utah County, Utah, Jack D. Brotherson Apr 1987

Plant Community Zonation In Response To Soil Gradients In A Saline Meadow Near Utah Lake, Utah County, Utah, Jack D. Brotherson

Great Basin Naturalist

Patterns of zonation along a saline meadow slope were studied. Different species associations were distributed in five zones along the slope which paralleled Utah Lake. The five zones, distinguished on the basis of dominant species and/or life form, were: saltgrass–annual weed, saltgrass-alkaligrass, saltgrass-forb, saltgrass, and spikerush. Soil, vegetation, and plant species data were taken. Patterns of change with respect to these factors were observed along the downslope gradient. Soil pH and soluble salts decreased downslope, while organic matter and moisture increased. Individual ions showed varying patterns. Vegetation and species patterns also varied with slope position. Annuals dominated the ridge tops, …

Zoogeography Of Great Basin Butterflies: Patterns Of Distribution And Differentiation, George T. Austin, Dennis D. Murphy Apr 1987

Zoogeography Of Great Basin Butterflies: Patterns Of Distribution And Differentiation, George T. Austin, Dennis D. Murphy

Great Basin Naturalist

The butterflies of the Great Basin exhibit general patterns of distribution and speciation similar to those found for other taxa, particularly birds. Two major centers of infraspecific differentiation and coinciding distribution limits of taxa are identified, each with three subregions. Great Basin butterflies are characterized by pallidity and substantial endemism below the species level.

Age In Relationship To Stem Circumference And Stem Diameter In Cliffrose (Cowania Mexicana Var. Stansburiana) In Central Utah, J. D. Brotherson, K. P. Price, L. O'Rourke Apr 1987

Age In Relationship To Stem Circumference And Stem Diameter In Cliffrose (Cowania Mexicana Var. Stansburiana) In Central Utah, J. D. Brotherson, K. P. Price, L. O'Rourke

Great Basin Naturalist

Cliffrose age in relation to stem circumference and stem diameter was studied in central Utah. Age-circumference and age-diameter predictor equations were developed from material obtained from 10 stands along a 65-km section of the Wasatch Mountains foothills. Ages estimated on material of known age by the two equations were highly similar. Age predictions were more accurate for young stems than for older stems. The oldest stem aged was 163 years.

Ecological Comparison Of Sympatric Populations Of Sand Lizards (Cophosaurus Texanus And Callisaurus Draconoides), Donald D. Smith, Philip A. Medica, Sherburn R. Sanborn

Great Basin Naturalist

Sympatric populations of Cophosaurus texanus and Callisaurus draconoides were periodically sampled from March 1973 through April 1974 at Burro Creek, Mohave County, Arizona. Callisaurus were also sampled at Rock Valley, Nye County, Nevada. Sex ratios were skewed in favor of males in the adult Cophosaurus but were equal in both adult populations of Callisaurus. Both species became sexually mature as yearlings. Mean clutch sizes were 3.55 (±0.83) for Cophosaurus, and 4.25 (±1.08) and 5.07 (±1.33) for Callisaurus at Burro Creek and Rock Valley respectively. Evidence of multiple clutches was exhibited by both species. Egg weight/body weight ratios for both species …


Field Clinic Procedures For Diagnosing Echinococcus Granulosus In Dogs, Ferron L. Andersen, M. John Ramsay Apr 1987

Field Clinic Procedures For Diagnosing Echinococcus Granulosus In Dogs, Ferron L. Andersen, M. John Ramsay

Great Basin Naturalist

Echinococcus granulosus is the causative parasite of hydatid disease in humans and represents a significant public health problem within endemic foci in all major continents of the world. This report gives a detailed set of instructions whereby four trained individuals can examine 15–20 dogs per hour for the presence of this organism. The procedure permits the baseline determination of the prevalence of this parasite within any specific population of dogs and also allows the periodic examination of the same animals to determine if recommended preventive and control measures for hydatid disease are being followed by sheep and dog owners in …


Parasites Of The Cutthroat Trout, Salmo Clarki, And Longnose Suckers, Catostomus Catostomus, From Yellowstone Lake, Wyoming, R. A. Heckmann, H. L. Ching Apr 1987

Parasites Of The Cutthroat Trout, Salmo Clarki, And Longnose Suckers, Catostomus Catostomus, From Yellowstone Lake, Wyoming, R. A. Heckmann, H. L. Ching

Great Basin Naturalist

Twenty-five cutthroat trout (Salmo clarki) and eight longnose suckers (Catostomus catostomus) from Yellowstone Lake, Wyoming, were collected and examined for parasites in 1985. Cutthroat trout had at least six different species of parasites that included both protozoans and helminths. The greatest number of parasite species on one fish was nine. Parasites added to the known list for cutthroat trout from Yellowstone Lake, Wyoming, were: Myxosoma sp., Diphyllobothrium ditremum, Diphyllobothrium dendriticum, Diplostomum baeri, and Posthodiplostomum minimum. These data were compared with a previous survey (1971) and a checklist of parasites of cutthroat trout in North America. There …

American Swallow Bug, Oeciacus Vicarius Horvath (Hemiptera: Cimicidae), In Hirundo Rustica And Petrochelidon Pyrrhonota Nests In West Central Colorado, Thomas Orr, Gary Mccallister

Great Basin Naturalist

Oeciacus vicarious bed bugs were collected from 32% of Hirundo rustica nests and 83% of Petrochelidon pyrrhonota nests on bridges in western Colorado in December 1984. A total of 409 bugs (158 adults and 251 juveniles) were counted in 47 nests, two months after the hosts had departed for the winter.


Bee Visitors Of Sweetvetch, Hedysarum Boreale Boreale (Leguminosae), And Their Pollen-Collecting Activities, Vincent J. Tepedino, Mark Stackhouse Apr 1987

Bee Visitors Of Sweetvetch, Hedysarum Boreale Boreale (Leguminosae), And Their Pollen-Collecting Activities, Vincent J. Tepedino, Mark Stackhouse

Great Basin Naturalist

The native bee fauna visiting and pollinating a population of sweetvetch in Grand Teton National Park was surveyed. The papilionaceous flowers were exploited by 37 bee species, most of which had long mouthparts. Most species collected pollen as well as nectar. Bees foraged most heavily in early afternoon when pollen was most abundant. However, there was no indication that bee species were competing for limited pollen resources: there was no difference among three time periods in percent sweetvetch pollen carried in the scopal pollen loads of bees nor was there any evidence that some species were displacing the foraging times …


Observations On Natural Enemies Of Western Spruce Budworm (Choristoneura Occidentalis Freeman) (Lepidoptera, Tortricidae) In The Rocky Mountain Area, Howard E. Evans Apr 1987

Observations On Natural Enemies Of Western Spruce Budworm (Choristoneura Occidentalis Freeman) (Lepidoptera, Tortricidae) In The Rocky Mountain Area, Howard E. Evans

Great Basin Naturalist

Three species of predators and parasites were found associated with western spruce budworm (Choristoneura occidentalis Freeman) (Lepidoptera, Tortricidae) in Larimer Co., Colorado. These were: Ancistrocerus antilope (Panzer) (Hymenoptera, Vespidae), Goniozus gracilicornis (Kieffer) (Hymenoptera, Bethylidae), and Ceromasia auricaudata Townsend (Diptera, Tachinidae). The first two species stored caterpillars in wooden trap nests, while the third was reared from final instar budworms.

Competition For Food And Space In A Heteromyid Community In The Great Basin Desert, Cliff A. Lemen, Patricia W. Freeman Jan 1987

Competition For Food And Space In A Heteromyid Community In The Great Basin Desert, Cliff A. Lemen, Patricia W. Freeman

Great Basin Naturalist

A series of removal experiments were performed on Dipodomys merriami, D. microps, and Perognathus longimembris to test for the importance of competition for food and microhabitats in a heteromyid community in the Great Basin Desert. Each of these species was removed singly to determine the short-term effects on the microhabitat preferences of the remaining species. We correctly predicted, based on differences in diet, that the removal of D. microps (a foliovore) would have no effect on D. merriami or P. longimembris (granivores). Using the dominance hierarchy theory, we correctly predicted that removal of a larger heteromyid, D. merriami, would have …


Drosophila Pseudoobscura (Diptera: Drosophilidae) Of The Great Basin Iv: A Release Experiment At Bryce Canyon, Monte E. Turner Jan 1987

Drosophila Pseudoobscura (Diptera: Drosophilidae) Of The Great Basin Iv: A Release Experiment At Bryce Canyon, Monte E. Turner

Great Basin Naturalist

Some populations of Drosophila pseudoobscura in the Great Basin have very little genetic variation for third chromosome inversion gene arrangements. These populations are essentially monomorphic for the Arrowhead gene arrangement. At Bryce Canyon, Utah, individuals with other gene arrangements (Standard, Pikes Peak, and Treeline) were released and their frequencies monitored. One generation after release, the released arrangements had increased in frequency from 0.7% to almost 10%. After overwintering, the arrangement frequencies were not statistically different from the prerelease samples. The samples did demonstrate a low-level retention of the released Pikes Peak arrangement. The decline in the released arrangements was probably …


Alpine Vascular Flora Of The Ruby Range, West Elk Mountains, Colorado, Emily L. Hartman, Mary Lou Rottman Jan 1987

Alpine Vascular Flora Of The Ruby Range, West Elk Mountains, Colorado, Emily L. Hartman, Mary Lou Rottman

Great Basin Naturalist

The Ruby Range is a northern extension of the West Elk Mountains of west central Colorado. Composed primarily of sedimentary rocks, the range is heavily faulted and intruded by many dikes and sills. Eight study areas, selected as representative of the major topographic features of the range, were analyzed floristically. A vascular flora of 220 species in 111 genera and 35 families is reported. The phytogeographic distribution of the flora is primarily alpine and western North American. The flora of the Ruby Range shows a 74% similarity to the flora of the San Juan Mountains to the southwest.


Douglas-Fir Dwarf Mistletoe Parasitizing Pacific Silver Fir In Northern California, Robert L. Mathiasen, Larry Loftis Jan 1987

Douglas-Fir Dwarf Mistletoe Parasitizing Pacific Silver Fir In Northern California, Robert L. Mathiasen, Larry Loftis

Great Basin Naturalist

Douglas-fir dwarf mistletoe (Arceuthobium douglasii) was found parasitizing Pacific silver fir (Abies amabilis) in northern Siskiyou County, California. This is the first report of Douglas-fir dwarf mistletoe on this host. Approximately 40% of the Pacific silver firs near heavily infected Douglas-firs were infected. The low level of infection on Pacific silver fir, unusually large swellings at the points of infection, and poor shoot production on infected branches indicate some degree of host-parasite incompatibility.
