Natural exposure to ultraviolet-B radiation in two species of chameleons from Madagascar…etc…

[kinyonga]

“Only on rare occasions were chameleons observed in areas with a UV Index (UVI) greater than 3.0, and the median UVI for both species was only 0.3. There was no daily temporal pattern in UV exposure for C. nasutum, but C. brevicorne was found in areas with lower UV levels in the late afternoon when compared to late morning.”…

I realize I’ve posted this before…but since the topic has come up recently, I thought I should post it again.


“Preliminary field data reveal that this species occupies UV irradiance Zone 4 in Madagascar, the highest zone for reptiles recorded“…

“Both Pete Hawkins and I have verified that UVI 3 does the job for veiled chameleons.”…
”Pete Hawkins raised up a female veiled chameleon under a UV Index of 3 and never gave D3 in her supplements. This female has laid successive clutches of fully calcified eggs. Perfect. Strong data point. I grabbed that and did a test with two pairs. One under UVI 3 and one under UVI 6. I confirmed his results of UVI 3. And with the second pair under UVI 6 I showed that more UVB does not produce healthier or bigger animals.”…
