Question

How do UV rays affect frogs and their eggs?

Answer 1

Frogs are indicator species whose global population declines are warnings of the state of the environment. Their permeable skin and dual lives in water and on land make them more vulnerable to environmental degradation. Disease, acidification and pollution are partially to blame for frog deaths and mutations, but the rise in ultraviolet radiation attributed to the thinning of the ozone layer also may be a contributing factor

Answer 2

Their eggs have no shells and are susceptible to damaging radiation. Increased UV-B rays associated with the thinning ozone layer kill frogs and their eggs, with the most threatened species living in high elevations where they are more likely to be exposed to more concentrated rays.
