| Abstract |
|
During the summer of 2002, we studied the benthic omnivore turtle guild inhabiting freshwater canals in central Broward County, Florida. Sampling with baited hoop traps, we captured 52 Chelydra serpentina, 34 Kinosternon baurii, and 4 Sternotherus odoratus in 576 trap nights. Throughout the canal system, C. serpentina was the dominant species in shallow (<1 m maximum depth) areas, while K. baurii dominated the deeper (>1 m) areas. Secondary sex ratios were 1:1 for all three species, but population size structure data indicate that impaired recruitment may threaten the long-term persistence of both C. serpentina and K. baurii.
