significant genetic populational 

 differences. Although, depending on 

 life history patterns, this may be 

 one indication of major estuaries 

 having distinct subpopulations such 

 as described by Weinstein and Yerger 

 (1976) for Cynoscion nebulosus . 



2. Long-term periodicity in 

 the flow of the Apalachicola River 

 and the Peace River, while approxi- 

 mately similar in duration, may be 

 the result of regional (local) cli- 

 matic effects. Thus, it may be im- 

 portant to view general estuarine 

 changes in periods much longer than 

 the annual cycle in order to identify 

 natural population oscillations from 

 those resulting from man-made changes 

 in flow.

Many of the observations for 

 Charlotte Harbor, particularly in 

 terms of the fauna, seasonal patterns 

 of flow, long-term cycles may have 

 analogues from about Estero Bay to 

 Tampa Bay because of similar climatic 

 and tidal conditions.
