You have to consider the fact that Tom Leuteritz published his PhD thesis from which this chart was taken in 2002; hence he probably did this study sometime in the late 90's to 2001, so the technology may not have been able to capture the details which can be had with today's instruments. I know he told me that the eggs were taking much longer to hatch than he had anticipated, and he had to replace the 6 month batteries with 1 year ones to continue getting his data.
Thanks for the input, Bill.
Yes the nests in that study were most all 2000, with one from 1999. SO we are talking almost 20 years ago. SO much has happened since then with the equipment we meer mortals have access to now! We can now see a complete time profile of the temperatures. I do that with every clutch of G platynota eggs I incubate. Would love to see if in a few in situ nests. I'm trying to get the Park Warden at Minsontaung Wildlife Sanctuary to put a few data loggers in some nests for me for G platynota. Communication is very slow and somewhat limited by her limited English and my total lack of Burmese!
