Abstract: In Israel, the oviparous softshell turtle Trionyx triunguis lays its eggs in nests buried in elevated sand bars along the banks of the Alexander river. We measured the temperatures and humidity prevailing in natural nests throughout the entire incubation period (78 days), and found that the eggs' hatchability was dependent upon the substrate wetness. In dry sand (water content 0. 11 per cent, water potential -2760 kPa), the eggs lost an average of 31 per cent of their initial mass and failed to hatch. In a wetter substrate, in which the water loss of the eggs did not exceed 15 per cent, the eggs hatched successfully.
