Electrophoresis Of Isoenzymes Of 16 Western Shrubs: Technique Development, R. L. Leonard, E. D. Mcarthur, D. J. Weber, B. W. Wood Dec 1981

Electrophoresis Of Isoenzymes Of 16 Western Shrubs: Technique Development, R. L. Leonard, E. D. Mcarthur, D. J. Weber, B. W. Wood

Great Basin Naturalist

Wildland shrubs have gained considerable attention in recent years due to increasing recognition of their values as animal feed, as wildlife habitat, and for land reclamation. Better management of the shrub resource will be possible through clearer taxonomic identification and better understanding of phylogenetic relationships. This study applied polyacrylamide gel electrophoresis and further developed this technique to address genetic relationships among 16 paired shrub species (genera: Artemisia, Chrysothamnus, Atriplex, Ceratoides, Sarcobatus, Purshia, Cowania, and Cercocarpus [Compositae, Chenopodiaceae, Rosaceae]). Cluster analysis of similarity values for total protein and 14 isoenzyme systems gave patterns of species relationships expected from classical morphological grounds …

Species Composition And Relative Abundance Of Adult Fish In Pyramid Lake, Nevada, Steven Vigg Dec 1981

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 …

Feeding Interrelations Of Native Fishes In A Sonoran Desert Stream, Donald C. Schreiber, W. L. Minckley Dec 1981

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 …

Notes On The Reproductive Biology Of Zigadenus Paniculatus, A Toxic Range Plant, V. J. Tepedino Dec 1981

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 …

Subaerial Algae Of Navajo National Monument, Arizona, Jeffrey R. Johansen, Samuel R. Rushforth, Jack D. Brotherson Dec 1981

Subaerial Algae Of Navajo National Monument, Arizona, Jeffrey R. Johansen, Samuel R. Rushforth, Jack D. Brotherson

Great Basin Naturalist

Samples from soils and other xeric substrates in Navajo National Monument, Navajo County, Arizona, were collected in 1978. After being moistened with deionized water for three days, these samples were analyzed for algae. Thirty algal taxa were identified. Five species of filamentous Cyanophyta comprised the majority of the biomass. Diatoms were ubiquitous in the soils although low in density. Diatom floras were very similar throughout the monument. Well-developed algal crusts were common in sites where grazing and excessive litter were absent.

History And Status Of The Franklin's Gull On Malheur National Wildlife Refuge, Oregon, Carroll D. Littlefield, Steven P. Thompson Dec 1981

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.

Summer Food Habits Of Coyotes In Central Wyoming, Joseph Tucker Springer, J. Steven Smith Dec 1981

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 …

Understory Vegetation In Fully Stocked Pinyon-Juniper Stands, Richard L. Everett, Susan Koniak Dec 1981

Understory Vegetation In Fully Stocked Pinyon-Juniper Stands, Richard L. Everett, Susan Koniak

Great Basin Naturalist

Ten fully stocked pinyon-juniper stands contained a total of 73 species in the understory, but the number of understory species in any one stand was moderately low (x̄ = 20). On each stand, species of at least five different plant groups were present in the understory (shrub, perennial grass, perennial forb, annual grass, or annual forb). A perennial grass, Sandberg bluegrass (Poa sandbergii), and a group of annual forbs with relatively high cover and constancy among stands appeared best adapted to coexist with the pinyon-juniper overstory. The proportion of total plant cover was greater on tree-associated microsites (duff …

Bald Eagle Winter Survey In The Snake River Canyon, Wyoming, Art H. Korhel, Tim W. Clark Dec 1981

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.

Association Of Rhabdocline Needle Blight And Epicormic Branching In Douglas-Fir, Ronald M. Lanner, James A. Bryan Dec 1981

Association Of Rhabdocline Needle Blight And Epicormic Branching In Douglas-Fir, Ronald M. Lanner, James A. Bryan

Great Basin Naturalist

In northern Utah, Douglas-firs (Pseudotsuga menziesii [Mirb.] Franco) with symptoms of Rhabdocline needle blight had a significantly higher frequency of epicormic branching than did healthy trees. It is not known whether Rhabdocline infection stimulates epicormy, or whether the proliferation of epicormics increases resistance to the disease.

Microenvironment And Nest Site Selection By Ring-Necked Pheasants In Utah, Alan K. Wood, Jack D. Brotherson Dec 1981

Microenvironment And Nest Site Selection By Ring-Necked Pheasants In Utah, Alan K. Wood, Jack D. Brotherson

Great Basin Naturalist

Vegetative and atmospheric parameters were evaluated at 16 different nest sites of ring-necked pheasants in Utah County, Utah, to determine which parameters are influential in the nest site selection process. These data indicate that total vegetative ground cover, high amounts of cover immediately surrounding the nest cavity, and drying power of the air are the parameters most influential in nest site selection.
