It's likely from other studies that there could be some influence of temperature during at least part of the incubation on the sex ratio..
.
I put some clutches of Sauromalus eggs in barely moist vermiculite and hatch them in my boa rooms (79-87deg F) and get a mostly even male-female sex ratio.. Clutches that go the distance out in the pens give similar, mostly even results.. the females work a lot, especially during the first half of the incubation.. piling up stuff, and sometimes removing it, from the nest sites.. It gets very hot in the pens (110-120deg F), what the temperatures are underground I have no clue.
.
Are you considering manipulating the temperatures to favor one sex over the other?
.
Why?
