@DocZ said…”I reversed the seasons to how they would occur in the northern hemisphere since in the summer I get too much natural light to fool the Cham into thinking it’s the cool season”…I did the reversed seasons too. I’m not sure if it would affect their circadianclock or not, but it didn’t seem to in any way I could see. People moving from one area of the world to another seem to cope with it…I think.

I just found especially with my leopard gecko that he slows down activity in the winter when ambient light is less than his enclosure light even if I do not change anything, and he’s more active earlier when light from a window nearby occurs before my pick for his morning sunrise so I just try to make his photoperiod more closely to his ambient environment because despite my best efforts, I can’t make the sun stay down when I’m not quite ready for it to come up

I don’t think (and I am entirely guessing) that if you want to change an animals season to more closely match local captive conditions that their biology would resist a reversal of seasons from their wild biology after a fairly short period of time in captivity
Captive bred animals should not have any biologically connected for months that cooler temps occur
Photoperiod, the one I can’t fix because all of my animals have/have had ambient light available is probably very important, and temp is a very easily adjusted parameter if you have the tools

My leopard gecko trio lived together in the same cage, under the reversed season changes, for over 19 years.
