Strawberry poison-dart frog in bromeliad
Frogs avoid damaging UV-B radiation, reducing extinction risk
Poison arrow frogs appear to make special effort to avoid exposure to damaging ultraviolet-B radiation, according to research published in the journal Biotropica. The findings are significant in light of increasing levels of UV-B radiation due to ozone depletion. UV-B radiation has been shown to increase the incidence of developmental abnormalities and may make frogs more susceptible to disease. It is believed to be one of several factors contributing to the rapid global decline in amphibians since 1980.
