The Role Of Economic Analysis In Public Range Management, B. Delworth Gardner

Faculty Publications

Economic analysis has a vital, if not indispensable, role to play in the management decisions of the Bureau of Land Management (BLM} if the national welfare is to be served effectively. This rather sweeping conclusion is justified by the nature of the management problems faced by the BLM and by the unique view of the world provided by the field of economics.

Notes On The Reproductive Biology Of Zigadenus Paniculatus, A Toxic Range Plant, V. J. Tepedino

Great Basin Naturalist

Zigadenus paniculatus is a toxic plant common on sagebrush foothills at middle elevations in the western United States. Plants produce several racemes from a single stalk. Flowering commences at the base of each raceme and proceeds upwards. The terminal raceme begins blooming first and is followed by lower racemes in sequential order. Flowers are markedly protandrous and incapable of autogamy. Observations do not support the idea that apomixis is a viable reproductive strategy. Plants are mostly self-incompatible; a few seeds were produced from geitonogamous hand pollinations. The pollen/ovule ratio was high, also suggesting outcrossing as the predominant mode of sexual …

Summer Food Habits Of Coyotes In Central Wyoming, Joseph Tucker Springer, J. Steven Smith

Great Basin Naturalist

Summer food habits of coyotes (Canis latrans) were investigated on a 3100-km² area in central Wyoming, divided into one deer-use area and five non-deer areas. Analysis of 404 scats (fecal samples) revealed an overall average of 63 percent occurrence of native ungulates, 63 percent leporids, 46 percent rodents, 14 percent livestock, and 11 percent birds. Pronghorn (Antilocapra Americana) was the ungulate most frequently consumed, occurring in about 87 percent of the scats. Mule deer (Odocoileus hemionus) occurred in only 8 percent, and in 5 percent the native ungulate remains were not identifiable beyond …

Bald Eagle Winter Survey In The Snake River Canyon, Wyoming, Art H. Korhel, Tim W. Clark

Great Basin Naturalist

A 5-year winter Bald Eagle survey was conducted along 22 km of the Snake River Canyon in northwestern Wyoming. Surveys were done on 94 days requiring 1,414 hrs and 1,888 km driving. In all, 220 (85 percent adults) Bald Eagles were seen. Seventy-seven percent of all eagles were perching, 15 percent were flying, 4 percent were feeding on road-killed mule deer, and 4 percent were flying low over water. Perching sites were identified as 32 percent cottonwoods, 30 percent spruce, 17 percent Douglas-fir, and 22 percent other. Eagles were somewhat clumped in distribution.

Feeding Interrelations Of Native Fishes In A Sonoran Desert Stream, Donald C. Schreiber, W. L. Minckley

Great Basin Naturalist

Native fishes in Aravaipa Creek, Arizona, cropped foods proportional to abundance of those foods within the system. Ephemeropteran nymphs and adults comprised the major prey of 5 of 7 fishes (Gila robusta, Meda fulgida, Rhinichthys osculus, Tiaroga cobitis, and Catostomus insignis). The omnivorous Agosia chrysogaster ate almost as many nymphal mayflies as did the carnivores. Pantosteus clarki was herbivorous, taking animals only when they were abundant. When ephemeropterans decreased in abundance, a shift by some fish species occurred to other locally or seasonally abundant items. Other fishes continued to feed upon the same foods throughout the year. Abundance …

Species Composition And Relative Abundance Of Adult Fish In Pyramid Lake, Nevada, Steven Vigg

Great Basin Naturalist

Pyramid Lake fish populations were sampled with nets on a monthly basis from November 1975 through December 1977. Fish species were taken in the following order of numerical relative abundance: tui chub (Gila bicolor), Tahoe sucker (Catostomus tahoensis), Lahontan cutthroat trout (Salmo clarki henshawi) including cutthroat-rainbow hybrids, cui-ui (Chasmistes cujus), and Sacramento perch (Archoplites interruptus). Relative abundance estimates are discussed with respect to seasonal availability, spatial distribution of the fish, sampling bias of the fishing methods, and biomass of the fish. Recent temporal trends in the population structure of the …

History And Status Of The Franklin's Gull On Malheur National Wildlife Refuge, Oregon, Carroll D. Littlefield, Steven P. Thompson

Great Basin Naturalist

Franklin's Gulls first arrived in southeast Oregon in 1943, but the first nest was not located until 1948. From 1949 to 1964 gull numbers showed annual fluctuations. An increase began in 1965 and continued through 1980. By 1980 an estimated 2500 Franklin's Gulls were nesting on Malheur National Wildlife Refuge, Harney County, Oregon. The species arrives in April and nesting begins by 1 June. Average nest and egg measurements were similar to those from other areas within the species range.

Contributions To The Life History Of Sacramento Perch, Archoplites Interruptus, In Pyramid Lake, Nevada, Steven Vigg, Paul A. Kucera

Great Basin Naturalist

During a two-year period (1976–1977), 180 Sacramento perch (Archoplites interruptus) were sampled from Pyramid Lake, Nevada, on a monthly basis using several capture methods in all lake areas. Age and growth determinations of these fish were inconsistent with previous research on this species. Sacramento perch are entirely carnivorous, adults feeding primarily on tui chub (Gila bicolor). Fish accounted for 6 percent of the diet (by volume) of Sacramento perch less than 300 mm fork length, and 98 percent for those exceeding 300 mm. Amphipods, Odonata, and Chironomidae composed 6.3, 5.7, and 1.8 percent, respectively, of the …

Bionomics And Control Of The Walnut Spanworm, Phigalia Plumogeraria (Hulst), On Bitterbrush In Utah, Malcolm M. Furniss, Gordon A. Van Epps

Great Basin Naturalist

In 1979, the walnut spanworm defoliated a 1 ha bitterbrush seed orchard near Nephi, Utah. No seed was produced for two years thereafter due to feeding damage. Life stages were described and illustrated. The female is brachypterous and incapable of flight. First instar larvae readily drop on their silk threads and probably are dispersed by wind. The insect has one annual generation. Moths laid an average of 159 eggs per cluster in April; larvae began to appear in early May and matured by the first week of June. The pupal period extended from June until mid-April. The parasitic bombyliid, Villa …

Bird Community Composition In Relation To Habitat And Season In Betatakin Canyon, Navajo National Monument, Arizona, Jack D. Brotherson, Lee A. Szyska, William E. Evenson

Great Basin Naturalist

Bird species density, diversity, and species richness in relation to habitat and seasonal variations were studied in the Betatakin Canyon area of Navajo National Monument, Arizona. The two most prominent habitat types are a riparian forest deep in the canyon bottom and a mature pinyon-juniper woodland on the mesas and slopes above the canyon. One hundred thirty-five species of birds were encountered during the study and recorded by season and habitat. The avifauna assemblages demonstrate definite habitat selection into groups associated with the riparian and pinyon-juniper woodland communities. Diversity, density, and species richness were greatest in the riparian habitat during …

Theses and Dissertations

The purpose of this study was to investigate the attitudes of Clog Dancers in regards to forming one unified National Clog Dancing Association.

The study found the following results: 1) the majority of clog dancers and leaders want one unified National Association, 2) competition and exhibition festivals should be continued, 3) dance terminology should be standardized, and 4) the more number of years a person is involved in clog dancing the more they want a unified National _Organization.

The Invertebrate Fauna Of The Caves Of The Uinta Mountains, Northeastern Utah, Stewart B. Peck

Great Basin Naturalist

Seven large caves in the Uinta Mountains, Utah, were surveyed for their invertebrate faunas. Thirty-eight species were found, and 30 of these are typical cave inhabitants. Diptera are the predominant group. Cave-restricted species are an amphipod, two diplurans, and possibly a Rhagidia mite. The caves were probablv uninhabitable in the past glacial because of severe periglacial environmental conditions, and the faunas have moved into the present cave sites since deglaciation of the Uintas.

Evaluating The Relationship Between Mule Deer Pellet-Group Data And Available Winter Range, Using Landsat Imagery, John W. Wyckoff

Great Basin Naturalist

In this study, mule deer population trend data (deer-days-use/hectare) were statistically analyzed with range area data that were extracted from LANDSAT satellite imagery. The remote sensing techniques developed use multidate, winter images of an area in central Utah. Snow-covered areas and vegetational areas mapped from the imagery were composited into 26 maps representing the approximate winter range available to mule deer on 26 dates over a five-year period (1972–1977). Utah State Division of Wildlife Resources pellet-group transect data were statistically analyzed with range data measured from the satellite imagery. Range area accounted for a fairly large proportion of the variation …

Time Budgets Of Wyoming Ground Squirrels, Spermophilus Elegans, David A. Zegers

Great Basin Naturalist

Time budget of free-living adult Spermophilus elegans differed significantly from that of juveniles in the Front Range of the Rockies during 1974–1975. No differences were found between males and females. Hour of day, day since emergence, air temperature, cloud cover, and presence of predators all correlated with the frequency of various components of the time budget.
