While we generally understand the optimal ultraviolet B (UVB) environment for the growth and reproduction of female Panther Chameleons Furcifer pardalis, we do not know the relative importance of UVB irradiance and dose for optimal husbandry outcomes

In 1989 a mark–recapture study of a free-ranging urban population of Pantherophis obsoletus inhabiting the 38.5-ha grounds of the Dallas Zoo (Dallas, Texas) was undertaken and has continued until the present time. Seasonal activity occurred from la

We monitored daily patterns of natural ultraviolet-B (UVB) exposure (measured using the ultraviolet index [UVI]) of the Texas horned lizard (Phrynosoma cornutum) in North Central Texas. The animals were active on unpaved road surfaces on warm sunny d

In Jamaica, free-living male and female-sized Anolis sagrei are exposed to more natural ultraviolet-B (UVB) from sunlight than male and female-sized Anolis lineatopus. In the laboratory, we tested predictions derived from the hypothesis that Anolis p

The gamete-specific effects of UV radiation on fertilization in the invasive freshwater zebra mussel (Dreissena polymorpha) are addressed. Both eggs and sperm of zebra mussels were highly sensitive to UVB. Sperm irradiated with 118 mJ/cm2 UVB showed

We studied the effects of ultraviolet B (UVB) exposure or administration of dietary vitamin D3 on serum vitamin D3, serum 25-hydroxyvitamin D3 (25[OH]D), calcium, and phosphorus in juvenile black-throated monitor lizards (Varanus albigularis) deprive

Ultraviolet B (UVB) irradiation (285-320 nm) is considered important for metabolic processes and reproduction in many reptile species by facilitating the synthesis of vitamin D(3). In captivity, UVB radiation reaching an animal may be diminished by t

We compared the natural ultraviolet B (UV‐B) exposure, dietary vitamin D, and skin‐generated vitamin D synthesis for adult males of two species of Jamaican anoles. The more shade‐tolerant and thermal‐conforming Anolis lineotopus merope, rarel

We have previously documented that chronic UVB exposure of female panther chameleons within a specified dose range is critical for hatching success of their eggs. We have also documented that the mechanism of this effect includes the enhancement of v
