Amphibians threatened with extinction by effects of streetlights and illuminated buildings

Summary:

Study suggests artificial lighting stunts growth of toads and drives frogs from breeding grounds

Lighting from cars, buildings and streetlights is keeping toads up at night and stunting their growth, while also preventing frogs from laying their eggs, according to a new study.

In populations of amphibians that are already in severe decline thanks to toxic chemicals, diseases and habitat destruction, the disturbance caused by light pollution could be pushing them over the edge.

Artificial lights have transformed the night-time environment across a fifth of the planet’s surface and this is expected to increase rapidly in coming years.

Despite the scale of this disturbance, relatively little is known about the impact this is having on the animals whose habitats have been profoundly changed by 24-hour lighting.  The Independent
