This video from the USA says about itself:
Ashuelot Valley Environmental Observatory organizes volunteers to help amphibians cross roads during migration to vernal pools to breed.
Translated from the Dutch herpetologists of RAVON today:
Last weekend, just after the first frost period stopped, the first amphibians woke up and started walking. On January 7 in Gelderland province, a common toad was found on a road, and in Drenthe province, some common and edible frogs were reported. In the south of Limburg province, the first fire salamander was observed.

Zoologists in Germany have analyzed the central factor for the development of morphologically distinctive features of tadpoles. The researchers were able to show that it is mostly the FOXN3 gene that influences the development of the cartilages in the oral region and the gills. These structures in particular belong to the evolutionary new developments typical of frogs: here.

May 2011: Buoyed by successes in the investigation into a killer frog disease, teams at wildlife charity Froglife and the Zoological Society of London (ZSL) are gearing up for the next stage of the study. The public are urged to continue their support as knowledge about the deadly ranavirus advances: here.
