Temperature requirements/difference in sub-species

[Dakota]

what they do show is the vast variety of differences in climate these animals live in and that there husbandry isnt identical,and that theres different ways to do things successfully not one set recipe for success

I agree. What surprised me the most is the difference in the Indonesians.. I figured they would be the same?

ypu need to dig deeper dakota,average temps can be decieving,not a great actual thing to go off,plus you will find a huge variety even in a graph from one location,or some are actually from a different place with same or similar name,eg your bluemountain one

look at a bigger variety and more than just averages,it will show if you may have iffy ones

And most importantly remember thats ambient average air temp,most dont curl up exposed to ambient temps,in melb for instance,those temps are bad for easterns,they are just adaptable and find areas offering warmth above what natures throwing at them

Yeah, I'm going to look at some better known climate people thingy~ What others should I post other than "Average Highs and Lows"? I agree with the variation. I looked up my place.. and it said the lowest average was 31.. and it wasn't uncommon for it to get 17 at some point of the winter..

Also, we need to keep in mind many microhabitats can be much warmer or colder. These are probably air temps, but with bluetongue lizards surface temperatures are quite important.

I am continually amazed by how cold hardy blotchies are! I'm guessing breeding failure without proper brumation may limit them to more temperate climes? However, even in very cold areas you can tempgun some very high temperatures. It can be 60 degrees outside but particularly on a calm day a rock exposed to the sun can hit 90F without too much trouble...and a lizard basking nearby could do almost as well. I've been in the desert in 60-70 degree weather and the sand in some places can still become uncomfortable to walk in(and resident lizards were taking shelter in the shade in January!). Conversely in shady moist climes it may be difficult to find a spot much warmer than air temperature, but. Studies looking at actual cloacal/body temps of active and brumating blotchies could help a lot(a few studies have been done on scincoides and PBT for active animals is about 30C.

The animals can also change their activity. During the hotter parts of the year at least Northern bluetongues were found to be crespucular animals.

Interestingly with blueys breeders have reported success with lower wintertime temps than they would experience in the wild as well.
