The phytoplankton and limnological characteristics of Lago Rupanco, Osorno, Chile

Creator:: Donoso, Teresa G.
Abstract:: Lago Rupanco is located in the central plain of Chile (Borgel, 1964) at 40° 50' S; 72° 30' W. It lies at 117 m above sea level, and corresponds to type 28c of Hutchinson's (1967) classification. Lago Rupanco is a warm, monomictic lake, with winter circulation and summer stratification. Physical,...

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...

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,...

Responses of algal populations to parasitism by Aphelidium chlorococcarum and chytrids in an Oregon sewage lagoon

Creator:: Woods, Wendy W.
Abstract:: The abundance of algal species and their parasites was monitored weekly for two years in a sewage lagoon at the Corvallis Airport, Oregon. During the cooler months, Euglena species were dominant followed by a Chlamydomonas assemblage in the spring and a predominantly Scenedesmus assemblage in the summer and fall. Parasites...

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...

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...

Effect of nutrient enrichment on marine benthic diatoms in Yaquina Bay, Oregon

Creator:: Cardon, Nanette Clark
Abstract:: Sediment was fertilized with f/2 algal growth medium in situ and in the laboratory daily for one week. Sampling strategy incorporated two intertidal heights and two sites. Experiments were done in August and January. No significant changes in chlorophyll a or diatom community structure were observed after ten days of...

Development, reproductive morphology, and cytology of Halosaccion glandiforme (Gmelin) Ruprecht (Rhodophyceae, Palmariales)

Creator:: Mitman, Grant Gregory
Abstract:: Halosaccion glandiforme, a member of the family Palmariaceae, is a common macrophyte found in the high to middle intertidal zones of the north temperate Pacific Ocean. Plants were grown in culture from spores and the lift history was critically examined by the use of scanning EM and light microscopy. H....

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...

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...
