My results are consistent with this interpretation in that highly stoloniferous colonies showed evidence of overgrowth regardless of intercolony spacing; however, in the absence of highly stoloniferous phenot\ pes. this does not appear to be the case. Overgrowth, while likely predominating in many Hydmctinia popula- tions as a result of recruitment patterns and available gas- tropod substrata (Buss and Yund. 1988; Yund and Parker. 1989). may not be the inevitable product of intraspecific competition in H. [CM]. Differences in the outcome of competitive encounters based on colony size are important ecologically and evolu- tionarily only if the frequency of encounters between small and large colonies varies predictably in natural Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Marine Biological Laboratory (Woods Hole, Mass. ); Marine Biological Laboratory (Woods Hole, Mass. ).
