As humans expand near and into natural habitats, fragile ecosystems become affected by our artificial night lighting. Amphibians are an important part of forest and aquatic ecosystems, and they are very sensitive to environmental changes. For example, they are affected by chemical pollutants because of their skin. Frogs and toads can hibernate in winter and even inside mud because oxygen can pass right through their skin, unfortunately, so can chemicals that they wouldn't want, if they had any choice. As such, they are important indicator species of the health of ecosystems. 

Light pollution may also contribute to global decline of amphibians, because many amphibians are nocturnally active or have biological rhythms regulated by light. Wise's paper summarized research looking at the impact of light pollution on amphibians, using some example laboratory experiments, field experiments, and natural (observational) studies.
