Early Dutch amphibian migration

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.

Dutch amphibian migration will really start in spring.

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.

  1. Exotic toad breeding first

    Published Date: 07 March 2011

    AQUARISTS at Deep Sea World in North Queensferry have successfully bred an exotic species of toxic fire-bellied toad for the first time.
    Seven tadpoles have been born, with dozens of eggs still waiting to hatch out.

    Originally from China, Russia and Korea, oriental fire-bellied toads get their name from their distinctive underbellies which flash coloured spots as a warning to would-be predators.

    Deep Sea World aquarist Paul Strachan said: “It’s fantastic news that the toads have bred successfully for the first time and it’s a great start to our amphibian breeding season.”
