Are we getting an idea of the amount of
UVB that "basking" reptiles
are designed to be exposed to?
After a long conversation with Steve at Solartech about this meter
the other day, I was very encouraged to find that this meter was
designed to "peak" at the 295-298 nanometer range, meaning that even
though it's a broad ban meter, it is most efficient at that range.
Also I would like to thank David Kroughoff for talking Steve into
developing the 6.2 meter. Dr. Holick at Boston U uses one of the very
meters that we have in his much published research. It's amazing what
we reptile "nuts" can accomplish.
A quick side point is that Dr Holick does not endorse the rumor that
a few minutes a day of the natural sun will have any sufficient photo-
chembiological effects on reptiles that regularly spend many hours a
day under direct sun light.
"Noctural/
crepuscular house geckos Hemidactylus turcicus are active in
low UV-B light environments, yet they have skins highly sensitive
regarding UV-B-induced vitamin D3 synthesis. Conversely,
diurnal Texas spiny lizards are active in higher UV-B
light environments but have skins less sensitive regarding
UV-B-induced vitamin D3 synthesis." Ferguson, 2002
Neither does Ferguson, Gehrmann.
Best wishes to all,
