In Reply to: Iggies incubatiion sex determination posted by Sergio on June 29, 1999 at 12:15:02:
Don't know if this will tell you much, but pg 213 in Herpetology(1998: Pough, Andrews, Cadle, Crump, Savitzky and Wells) claims temp dependant sex determination for Iguanids...
It also references some articles, the following two might give more info:
Janzen, F.J. and G.L. Paukstis. 1991. Environmental sex determinatino in reptiles: Ecology, evolution and experimental design. Quarterly Review of Biology 66:149-179.
and
Viets, B.E., M.A. Ewert, L.G. Talent and C.E. Nelson. 1994. Sex-determining mechanisms in squamate reptiles. Journal of Experimental Zoology 270:45-56.
It also says the most common patterns in lizards are males at intermediate temps (between 20 and 40 celcius) OR males at high temps only - doesn't say which scenario fits Iguanids though...
Good luck!
