|
Ultraviolet (UV) light rays in the lower B range (295-300nm) serve as a catalyst for production of vitamin D3 in many species. Turtles are exposed to UV rays through basking, and since vitamin D3 is essential to the uptake of dietary calcium, UV light is considered important for growth in these animals. We studied the effect of UV bulbs on growth in slider turtles (Trachemys scripta) from hatching to 8 months of age. Sliders were used because their generalist diet and habitat preferences were likely to free them from confounding effects that could be experienced with more delicate species. We maintained 243 specimens under 3 light treatments – control (no UV), fluorescent (ZooMed Repti-Sun 5.0®), and mercury vapor (T-Rex Active UV Heat®) – and replicated to provide 3 groups and bulbs per treatment. We took initial and final measurements on carapace length, plastron length, and mass for each specimen, and analyzed results by comparing growth for each treatment and for each group with an analysis of variance (ANOVA). We found no significant difference between treatments or groups. Turtles in this study had similar growth regardless of exposure to UV light.
