An Ecological Study Of Bristlecone Pine (Pinus Longaeva) In Utah And Eastern Nevada, R. D. Hiebert, J. L. Hamrick
An Ecological Study Of Bristlecone Pine (Pinus Longaeva) In Utah And Eastern Nevada, R. D. Hiebert, J. L. Hamrick
Great Basin Naturalist
This paper presents data on the distribution of Pinus longaeva on the Markagunt Plateau, Utah; and the Snake, Egan, and White Pine ranges of eastern Nevada. It also presents data on the present-day density and age structure of three P. longaeva populations and the growth rates of individual trees within these populations.
Conifer species richness and the relative abundance of P. longaeva varies clinally from the Markagunt Plateau to the White Pine Range. The Markagunt Plateau has relatively high conifer species richness (10 species) and low relative abundance of P. longaeva (1%). The White Pine Range has low conifer richness …
In Memoriam: Seville Flowers (1900–1968), William H. Behle
In Memoriam: Seville Flowers (1900–1968), William H. Behle
Great Basin Naturalist
Seville Flowers was the foremost authority of his time on cryptogamic botany in the intermountain region, having published monographs on the mosses, lichens, and ferns of Utah. He also had strong interests in algae, grasses, composites, and the history of botany. In addition to his systematic research, his expertise extended to field ecology. Early in his career he made a classic study of the vegetation of the Great Salt Lake region that led in later years to his participation in the ecological studies at Dugway Proving Grounds in western Utah. Still later he had charge of the predam vegetative surveys …
Ecological Studies Of A Regulated Stream: Huntington River, Emery County, Utah, Robert N. Winget
Ecological Studies Of A Regulated Stream: Huntington River, Emery County, Utah, Robert N. Winget
Great Basin Naturalist
A 36.9 × 106 m3 reservoir constructed on Huntington River, Emery County, Utah, resulted in changes in physical habitat, water quality, temperature, and flow regime. The greatest changes in physical habitat resulted from: (1) sediment additions from dam and road construction plus erosion of reservoir basin during filling; and (2) changing stream flow from a spring high runoff regime to a moderated flow regime. Elimination of spring nutrient concentration peaks and overall reduction of total dissolved nutrient availability in the river plus moderate reductions in pH were the most apparent water quality changes below the reservoir. Water temperature …
Naturalization And Habitat Relationships Of Bitter Nightshade (Solanum Dulcamara) In Central Utah, Jack D. Brotherson, Kevin P. Price
Naturalization And Habitat Relationships Of Bitter Nightshade (Solanum Dulcamara) In Central Utah, Jack D. Brotherson, Kevin P. Price
Great Basin Naturalist
Ten plant communities containing bitter nightshade (Solanum dulcamara) were studied and the ecology and naturalizing relationships of bitter nightshade in central Utah area were investigated. Biotic and abiotic factors from each area were statistically analyzed. The data indicated that bitter nightshade was negatively correlated (P < 0.01) with perennial grass cover and positively correlated with tree overstory. Bitter nightshade reached its highest development in heavily shaded areas. No other habitat factors correlated with the presence of bitter nightshade. This lack of environmental constraints along with bitter nightshade's bright red fruits, which are readily consumed by birds, suggests possible reasons for the rapid and successful invasion of the plant into the Utah Lake area.
Autumn And Winter Food Habits Of Bobcats In Washington State, Steven T. Knick, Steven J. Sweeney, J. Richard Alldredge, J. David Brittell
Autumn And Winter Food Habits Of Bobcats In Washington State, Steven T. Knick, Steven J. Sweeney, J. Richard Alldredge, J. David Brittell
Great Basin Naturalist
The stomach contents were examined from 324 western Washington bobcats (Felis rufus) and 123 from eastern Washington taken by hunters from 1976 through 1980, for major prey items as well as sex- and age-related differences in diet. Western Washington bobcats ate primarily mountain beavers (Aplodontia rufa) (42% occurrence) and snowshoe hares (Lepus americanus) (26%). Within that population females ate larger quantities of smaller prey such as Douglas squirrels (Tamiasciurus douglasi) and lesser amounts of deer (Odocoileus sp.) than males. Bobcat diets in eastern Washington were more diverse; main foods consisted of …
