This investigation will explore the evolutionary consequences of                variable recruitment in a colonial hydroid.  Work to date has                   demonstrated that: 1) recruitment density varies among isolated                 populations and determines the intensity of intraspecific                       competition;  2) colonies display genetically based variation in                colony morphology that determines intraspecific competitive                     ability; and 3) the morphologies present in population are                      correlated with the observed level of competition.  These                       preliminary data suggest that recruitment density establishes the               selective regime that determines the suite of morphological                     characters present in a population.  This hypothesis will be                    tested by experimentally manipulating recruitment density in four               populations and while following three other populations as                      controls.  This research will contribute to our knowledge of                    marine populations by examining the potential for variation in                  recruitment density to generate evolutionary change in species                  with limited gene flow among populations.
