Effect of monochromatic light on early development of amphibians in experiments

We studied the impact of environmental color on the early development of two species of Anura ( Rana arvalis, Rana temporaria ) and one Caudata species ( Triturus cristatus ). The development rate of Triturus cristatus eggs increased with green-blue light. The illumination color did not affect the rate of embryonic development in species with a short period of early development ( Rana arvalis and Rana temporaria ). Mortality at embryonic stages varied in different species. In all species red light negatively affected the survival rate of developing eggs. The larvae that started active feeding of all three species were larger in green-blue light than with white and, naturally, red, light.
