| Abstract |
|
Three Chelydra serpentina nests were monitored from September through October 1993. Maximum natality was 92% (mean 33.73%) and seemed to be associated with high temperature, abundant potasium and a moderate concentration of calcium in the soil. Nests were located at less than 80 m from water and soil characteristicaçs were: 21.8-22.9§C, clay-loam texture, penetrability index 0.27-0.87 kg/cm-2, humidity 48-74%
