The role of the egg jelly coat in protectingHyla regilla andBufo canorus embryos from ultraviolet B radiation during development

Abstract
Previous studies have suggested that Ultraviolet B (UVB) radiation may play a role in amphibian population declines. Some of these studies also indicate that egg hatching success is unaltered in some species of anurans as a result of UVB exposure. It has been proposed that the egg mass jelly provides photoprotection to the developing embryos.
