Creator:: Dalton, Charles Eddison
Resource Type:: Masters Thesis

A field and culture study of some freshwater algae

Creator:: McLachlan, J. L. (Jack Lamont), 1930-
Resource Type:: Masters Thesis

The humic water of Klamath Marsh and its effect on the growth of Anabaena cyclindrica Lemm. in culture

Creator:: Peek, Chester Allen
Resource Type:: Dissertation

Physiological ecology and structure of benthic communities in a woodland stream

Creator:: Reese, Weldon Harold
Abstract:: This thesis reports a portion of a general ecological study of a stream under conditions of controlled flow and low levels of organic enrichment. It is concerned with the effects of experimental variations of light intensity and concentration of soluble organic enrichment imposed on seasonal variations of temperature and total...

Requirement for the growth and maintenance of Alphanizomenon flos-aquae in culture

Creator:: O'Flaherty, Larrance Michael
Abstract:: Aphanizomenon flos-aquae from Upper Klamath Lake, Oregon was introduced into culture in a precipitate -free medium developed by modification of McLachlan's ASM medium. This medium ASMT No. 8 contained no organic substances other than ethylendiaminetetraacetate (EDTA) and Trishydroxymethylamino methane (Tris), and was developed by modifying the concentrations of certain elements,...

Primary productivity and community structure of an estuarine impoundment

Creator:: Lyford, John Higgins
Abstract:: An impounded estuary was employed to study primary productivity, community respiration, and community structure as they related to seasonal and temporal succession, salinity, and water temperature. Plankton metabolism was studied by means of the light-and dark-bottle technique. Benthic community metabolism was determined by using the "diurnal oxygen curve" method. Four...

Mineral requirements for the growth of Anabaena spiroides in vitro

Creator:: Volk, Sherry Louise
Abstract:: The major nutrient requirements of the blue-green alga Anabaena spiroides Klebahn were investigated. It was hoped that the results would allow the development of a balanced culture medium in which the alga would exhibit rapid growth and retain typical morphological characteristics. The alga was isolated from Upper Klamath Lake, Oregon,...

Growth of Aphanizomenon flos-aquae in defined media

Creator:: O'Flaherty, Larrance Michael Arthur, 1941-
Abstract:: A strain of Aphanizomenon flos-aquae Born. et Flah. has been introduced into culture and maintained since August of 1964 in completely defined media. It exhibits the planktonic, colonial flake form found in nature, and both heterocysts and akinetes are present. The color and size of the flake and general appearance...

Effect of kraft mill effluent on structure and function of periphyton communities

Creator:: Williams, Harvey Dean
Abstract:: Raw and biologically stabilized Kraft mill effluents were introduced into laboratory artificial streams at a ratio of 15 ml per liter of water over a two year period. Effluent from the stabilization pond of a second mill was introduced at concentrations of from 5 to 40 ml per liter of...
Resource Type:: Dissertation

The effects of logging on periphyton communities of coastal streams

Creator:: Hansmann, Eugene W. (Eugene William), 1933-
Abstract:: The purpose of this study was to investigate the effects of logging on the productivity, structure and biomass of a periphyton community developed in mountain streams. The three streams used in this investigation were located in the coast range of Lincoln County, Oregon. They were selected for similarity of habitat,...
