Clutch-specific details associated with the hatchlings used in the raising trials and their incubation.

“30°C days” is the age an embryo would be had it been incubated at 30°C [47][48][49]. Spot nest temperature (Tn) was measured at the time of collection whereas mean (Tn.mean) and maximum (Tn.max) nest temperatures are crude estimates (Webb et al. 1987a,b,c). Lay and hatch days: January 1 = day 1. Hatchling sizes were measured 4 days after hatching, before feeding started. The mean seasonal maximum (Tmax: 1300 h) and minimum (Tmin: 0900 h) air temperatures during the 21 days of raising for the hatchlings from each clutch (Australian Bureau of Meteorology: Darwin airport). A = wild nests from the Adelaide River mainstream; BP/CB = captive bred; M = wild nest from Melacca swamp on Adelaide River floodplain.
