Ecology of benthic microalgae of estuarine intertidal sediments

Creator:: Riznyk, Raymond Zenon
Abstract:: The benthic microalgae of sediments of the two tidal flats in Yaquina Bay, Oregon were investigated to determine the environmental factors limiting the abundance and the horizontal and vertical distribution of these organisms. The Southbeach tidal flat which is under the marine realm of deposition consists of fine to medium...

The effect of mixing on the oxygen uptake rate of estuarine bottom deposits

Creator:: Martin, Duane Collins
Abstract:: A study of the effect of mixing on the oxygen uptake rate of estuarine bottom deposits is presented. The method of study involved the mixing of samples of bottom deposits with the overlying water to result in concentrations of suspended matter in the same order as observed in the estuary....

Some aspects of the comparative ecology of fishes associated with juvenile sockeye salmon, Oncorhynchus nerka (Walbaum), in the lakes of the Naknek river system, Alaska

Creator:: Wallace, Richard L.
Abstract:: A study of the distribution, relative abundance and diet of fishes sympatric with juvenile sockeye salmon, Oncorhynchus nerka (Walbaum), within the freshwater nursery areas of the Naknek River system was undertaken from 1961 to 1963. The study was part of an extensive investigation to determine what factors in the freshwater...

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...

The ecology of the timberline and alpine vegetation of the Three Sisters

Creator:: Van Vechten, George Wendell, III
Abstract:: This is a study of the ecology of the timberline and alpine vegetation of the Three Sisters which are located in the central Oregon Cascades. The Sisters are a close group of three 1O,000-foot volcanic peaks. Volcanic activity within the last few hundred years as well as recent glaciation have...

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. )...

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...
