Large differences in recruitment over the years had no apparent affect on the dominance of the major species. The seasonal fluctuation of benthic population abundance peaked in the spring and

While significant relationships were found, they may reflect common correlation with other factors that vary wit

Nitrogen limitation was possible in approximately one-half of the summer and early fall months sampled
