Biological and physical dynamics of a Georgia tidal creek
Hackney CT, Burbanck WD, Hackney OP. 1976. Biological and physical dynamics of a Georgia tidal creek. Chesapeake Science. 17(4):271-280
This study deals with the species composition, population dynamics and seasonal distribution of the nekton and epifauna inhabiting a tidal creek in Georgia. The physical and biological characteristics of five stations in and near a tidal creek were studied for 18 months. Tidal creeks aid tidal rivers are differentiated and defined. Diel fluctuations of dissolved oxygen and temperature were greatest and tidal-induced salinity oscillations the least at the headwaters of the creek. Small salinity oscillations promoted a high overall diversity of fishes at the headwaters of the creek, even though few fish species maintained permanent populations there. Juvenile fishes were abundant in the summer and fall. Extreme temperature and low dissolved oxygen levels prompted a migration of fishes from these areas in late summer. Permanent fish populations were found at the mouth of the creek and in an adjacent tidal river.
