Forest associations and secondary plant succession in the southern Oregon coastal range

Creator:: Bailey, Arthur Wesley, 1938-
Abstract:: Forest associations, secondary succession, and relationships of plant communities to Roosevelt elk were investigated. Stratification of vegetation into ecological units and an understanding of secondary succession by habitat-type were a necessary first step in investigations into browsing of conifers by elk. The study was jointly conducted by the Oregon State...

Phytosociology of the ponderosa pine type on pumice soils in the Upper Williamson River Basin, Klamath County, Oregon

Creator:: Volland, Leonard A.
Abstract:: The study was conducted over approximately 191,000 acres in central Klamath County, Oregon. The research had three objectives: first, to describe and classify the seral and near-climax vegetation by using polyclimax principles; secondly, to determine the southern extension of five plant associations and one plant associes as previously described by...

An ecological reconnaissance of the artemisia steppe on the east central Owyee uplands of Oregon

Creator:: Culver, Roger Norman
Abstract:: As the management of range lands is intensified or as improvement activity is increased, a critical need is seen to refine the understanding of the ecology of these lands. If soil surveys on range lands are to be meaningful and useful, the relationship between the fundamental ecological units and the...

Characterization of selected plant communities within the Tillamook Burn in northwestern Oregon

Creator:: Bailey, Arthur W.
Abstract:: A study was initiated in 1961 to characterize seral plant communities in a part of the Cedar Creek drainage in the Tillamook Burn. Stratification of vegetation into ecological units was a necessary first step in conifer-animal damage studies supported by the Oregon State Game Commission. Reconnaissance information was recorded in...

Selective inhibition of ion absorption by uranyl

Creator:: Mason, Benjamin J.
Abstract:: The research presented in this thesis evaluated the effects of uranyl (UO₂⁺⁺) upon the absorption of Li, Na, K, Rb, and Cl. Due to the biological importance of Na and K, these two ions were studied in the greatest detail. The results of this research showed that, at UO₂⁺⁺ concentrations...

Vegetation changes of communities containing medusahead (Taeniatherum asperum (Sim.) Nevski) following herbicide, grazing, and mowing treatments

Creator:: Turner, Robert Bruce
Abstract:: Studies were conducted from 1962 to 1966 to investigate the effectiveness of several practices in manipulating medusahead (Taeniatherum asperum (Sim. ) Nevski) infested and/or dominated ecosystems by releasing competition in favor of perennial grasses. Several herbicide treatments were evaluated for selective control of medusahead and cheatgrass (Bromus tectorum L. )...

Vegetation and animal responses to grazing crested wheatgrass at three intensities and two seasons in southern Idaho

Creator:: Sharp, Lee Ajax
Abstract:: Land useable for livestock grazing in the western United States is diminishing because of spreading municipalities, irrigation developments, highway construction, recreational demands and withdrawals. Concurrently, the demand for livestock and livestock products is increasing because of a rapidly growing population. As a result, production from the grazing land that remains...

Some factors that affect pollination and seed formation in alfalfa, Medicago sativa L

Creator:: Bradner, Norman Richard
Abstract:: The objectives of this study were (a) to measure the amount of cross-pollination caused by three bee species at 10, 20 and 40 rods distance from a foreign pollen source, (b) to measure the effects of bee species, planting pattern and season on broad sense heritability estimates for seed yield...
