It is great food for thought Marc.
Using that temp information can be helpful....IF you understand nature.
With an average daytime temperature in the upper 80's.....I can find basking areas in excess of 100 degrees......I can also find cool areas in the 70s......On a 70 deg night, I can find places with temps in the high 80s...
When I go field herping, I bring my temp gun. Why? It is interesting to see how much temperatures vary in nature. On an average day this time of year, I can find temps ranging from 75 deg. to 115 deg....I can also find various moisture (humidity) levels....
...the thing is.....the reptiles can find their niche in the spectrum of environmental conditions alot better than most people know.
In captivity, some provide a set humidity....some a narrow temperature range....what would happen if you provide something outside of those commonly used conditions and give the animal a choise?
Reptiles are alot better at knowing what they need than their keepers. I say give them the options and let the animals make their own choices.
