Ultraviolet light and reptiles, amphibians

Ultraviolet lighting is integral for the growth and maintenance of many reptile and amphibian species. But providing an adequate source of light can be challenging. Many disease processes seen by veterinarians are attributed to ultraviolet lighting deficiencies. In mammals, disease due to excess ultraviolet lighting has been noted, and some veterinarians feel this may be […]

Ultraviolet vision and foraging in dip and plunge diving birds

Many fishes are sensitive to ultraviolet (UV) light and display UV markings during courtship. As UV scatters more than longer wavelengths of light, these signals are only effective at short distances, reducing the risk of detection by swimming predators. Such underwater scattering will be insignificant for dip and plunge diving birds, which prey on fishes […]

Provision of ultraviolet basking lights to indoor housed tropical birds and their effect on suspected vitamin D3 deficiency

Vitamin D deficiency (measured as 25(OH)D 3 ) can occur if birds are fed a vitamin D deficient diet and do not have access to ultraviolet B light (UVB). This can result in eggs with deficient yolks and consequent metabolic bone disease (MBD) in chicks. In this study, hypovitaminosis D was suspected in 31 adult […]
