Few of the amphibian species that occur in the Subarctic and in mountains are adapted to low sub-zero temperatures; most of these species overwinter underwater. It is believed that the distribution of the species that overwinter underwater can be limited by the low oxygen levels in waterbodies covered with ice. We show that the colonisation of the coldest areas of Northern Asia (to 71°N) by the Siberian wood frog (Rana amurensis) was facilitated by a unique adaptation, the ability to survive extreme hypoxia — and probably anoxia — in waterbodies during overwintering.

Native to central and southern Europe, the amphibious alpine newt breeds in shallow water, where its larvae are born, hatch and feed on plankton, before sprouting legs and moving to land. This timelapse video from the Dutch director Jan van IJken tracks the development of a single-celled zygote into the hatched larva of an alpine newt. Leer más.
