- Amphibians in Israel
This stamp series presents four of the seven amphibian speciescurrently inhabiting Israel. All four species are endangered locally or globally. Human activity has harmed the amphibian class more than other vertebrates. Due to their extreme sensitivity, amphibians serve as a bio-indicator of deterioration in the global environment. Amphibians have mainly been harmed in Israel as a result of their habitats being destroyed, but the key reason for their being endangered in the world is infectious diseases which are mostly spread as a result of trade in amphibians.
Eastern Spadefoot Toad (Pelobatessyriacus)
Near Eastern Fire Salamander (Salamandrainfraimmaculata)
The Near Eastern Fire Salamander lives along the edges of winter pools, streams and springs on Israel's Mediterranean coast,on Mt. Hermon, in the Galilee and in the Carmel mountains. Adults (up to 30 cms) are mainly active in the winter. Their black and orange coloring serves as a warning of the toxin that is secreted on their skin. Mating takes place on land. The male locates a female and lays a sperm sac, which the female absorbs. The female spawns 15-100 tadpoles in the water, which then develop over the course of a number of months until they roll out of the water. This species is classified as being endangered in Israel.
Hula Painted Frog (Latonianigriventer)
The Hula Painted Frog was first documented in the Hula Valley in the 1940's. Later, after not being seen since the 1950's, it was the first amphibian species in the world to be classified as being extinct. It was rediscovered in the Hula Nature Reserve in November 2011 and since then additional frogs of this species have been found in the reserve and the surrounding area, attesting to the existence of an active population. There is very little biological and ecological information about this species. It was recently discovered that the Hula Painted Frog belongs to a species that became extinct in Europe one million years ago. This finding means that this species as a living fossil. It is classified as being critically endangered in the world. - 现在购买:
