  • 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.

  • 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 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...
