 Knight Anoles - Temperature-dependent sex determination?

Does anyone know if Knight Anoles have Temperature-dependent sex determination, or if their sex is determined by XY chromosomes? I read that it differs among various anoles.

 Knight Anoles - Temperature-dependent sex determination?

25 species of Anolis have been tested to see if sex ratios skew from about 50/50 if egg incubation temperatures are altered. All 25 have shown that sex chromosomes, not TSD (temperatures), determine the sex of the baby. Unfortunately, Anolis equestris was not one of the ones tested, but I’d be inclined to think they too are sex chromosome-based, not TSD seeing as not one of the 25 studied have temperature effects.
