UVB-emitting LEDs for reptile lighting: Identifying the risks of nonsolar UV spectra
UVB lamps are used to provide reptiles housed indoors with the UV radiation necessary to synthesize vitamin D3 in their skin. Since 2019, UVB-LED lamps have been on sale for use in reptile husbandry. We performed spectral analysis and mapped the UV irradiance for 18 of these lamps. The positive benefits of UVB-LED lamps over […]
25-OH-D3, calcium, phosphorus, and alkaline phosphatase content in sera from captive polar bear (Ursus maritimus) cubs at the Denver Zoological Foundation
Abstract 10.1002/zoo.20131.abs After the development of rickets in two hand-reared polar bear (Ursus maritimus) cubs at the Denver Zoological Foundation we initiated a project opportunistically evaluating sera 25-OH-D3, calcium, phosphorus, and alkaline phosphatase levels in seven mother-reared polar bear cubs. From one to three serum samples were obtained while the cub was still in the […]
