  • 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...

  • 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...
