The study to be conducted by Walter K. Dodds is designed to                explore the ecological relationships in a macrophyte-grazer-epiphyte            system.  If epiphytes decrease macrophyte growth rate, then grazing of          those epiphytes can promote macrophyte growth.  The filamentous green           alga Cladophora, its epiphytes, and grazers of those epiphytes will be          used as a model system.  Field experiments will investigate vertical            structure in Cladophora mats via profiles of species abundance,                 photosynthesis, oxygen, pH and flow in natural mats and mats of                 artificial substrate (cotton).  Laboratory experiments will demonstrate         how epiphyte cover affects Cladophora growth, how grazing levels affect         epiphyte growth, and if grazers have specific adaptations which suit            them for life in Cladophora mats.  The host institution for this two-           year postdoctoral research fellowship is Montana State University.
