Hi Frank
Not sure if you are familiar with these sources, but it sure convinced me of the need for UVB for amphibians, but I guess that not all scientists are on board with this idea!

Much appreciated, Terry. Important articles...many variables, of course, and some conflicting info (on other species) but it's very promising to see that such good work is being done. I hope all is well, best, Frank
