Euproctus Montanus, Left Lateral View
''Euproctus'', the European mountain salamanders, is a genus of salamanders in the family Salamandridae from Sardinia and Corsica. Species There are two species: The Pyrenean brook salamander The Pyrenean brook salamander or Pyrenean newt ( an, guardafuents pirenenco; ca, tritó pirinenc; eu, uhandre piriniarra; es, tritón pirenaico), ''Calotriton asper'', is a largely aquatic species of salamander in the family Salamandridae. It ... used to be included in this genus as ''Euproctus asper'', but was moved to '' Calotriton'' in 2005. Its superficial similarity with ''Euproctus'' likely represents convergent evolution: strongly depressed head and body, and reduction or even absence of lungs, are adaptations to fast-running, well-oxygenated mountain streams.

Euproctus Montanus
The Corsican brook salamander or Corsican mountain newt (''Euproctus montanus'') is a species of salamander in the family Salamandridae. It is endemic to Corsica, an island in the Mediterranean Sea. The Corsican brook salamander is found primarily in rocky streams, springs, and rivers in forest and maquis at altitudes of over 600 m. Description The Corsican brook salamander is smaller than other closely related species, such as the Sardinian brook salamander (''Euproctus platycephalus'') and can grow to around in length, though a more typical size is . The head is long with a rounded snout, and the tail is oval in cross section and as long as the rest of the animal. The parotoid glands on the side of the neck are distinct. The males have spurs on the hind legs and a backwards-pointing conical cloaca, whereas the females have a cloaca with a ventral opening. The skin is smooth when it is living in the water, but becomes more granular when living on land. The colour is brown or ol ...

Amphibian Genera
Amphibians are four-limbed and ectothermic vertebrates of the class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. The young generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles like lizards but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed. With their complex reproductive needs and permeable skins, amphibians are often ecological indicators; in recent decades there has been a dramatic d ...

Newts
A newt is a salamander in the subfamily Pleurodelinae. The terrestrial juvenile phase is called an eft. Unlike other members of the family Salamandridae, newts are semiaquatic, alternating between aquatic and terrestrial habitats. Not all aquatic salamanders are considered newts, however. More than 100 known species of newts are found in North America, Europe, North Africa and Asia. Newts metamorphose through three distinct developmental life stages: aquatic larva, terrestrial juvenile (eft), and adult. Adult newts have lizard-like bodies and return to the water every year to breed, otherwise living in humid, cover-rich land habitats. Newts are threatened by habitat loss, fragmentation and pollution. Several species are endangered, and at least one species, the Yunnan lake newt, has become extinct recently. Etymology The Old English name of the animal was , (of unknown origin), resulting in Middle English ; this word was transformed irregularly into , , or . The initial ...

Convergent Evolution
Convergent evolution is the independent evolution of similar features in species of different periods or epochs in time. Convergent evolution creates analogous structures that have similar form or function but were not present in the last common ancestor of those groups. The cladistic term for the same phenomenon is homoplasy. The recurrent evolution of flight is a classic example, as flying insects, birds, pterosaurs, and bats have independently evolved the useful capacity of flight. Functionally similar features that have arisen through convergent evolution are ''analogous'', whereas ''homologous'' structures or traits have a common origin but can have dissimilar functions. Bird, bat, and pterosaur wings are analogous structures, but their forelimbs are homologous, sharing an ancestral state despite serving different functions. The opposite of convergence is divergent evolution, where related species evolve different traits. Convergent evolution is similar to paralle ...

Calotriton
''Calotriton'', or the European brook newts, is a genus of newts native to the Pyrenees and central Catalonia (Catalan Pre-coastal Range). These amphibians were formerly placed within genus '' Euproctus'', but the genus was resurrected in 2005. Instead of '' Euproctus'', they seem more closely related to ''Triturus'', their sister taxon. Evolution ''Calotriton'' and ''Triturus'' are estimated to have split approximately 8 myr ago. This may have been associated with adaptation to fast-running, well-oxygenated mountain streams (instead of ponds in ''Triturus''), leading to some superficial similarity with ''Euproctus'' in convergent evolution Convergent evolution is the independent evolution of similar features in species of different periods or epochs in time.

Pyrenean Brook Salamander
The Pyrenean brook salamander or Pyrenean newt ( an, guardafuents pirenenco; ca, tritó pirinenc; eu, uhandre piriniarra; es, tritón pirenaico), ''Calotriton asper'', is a largely aquatic species of salamander in the family Salamandridae. It is found in the Pyrenees of Andorra, France, and Spain. The IUCN lists it as least concern. Description The Pyrenean brook salamander grows to about in length, half of which is the laterally flattened tail. The females are usually larger than the males. The body is sturdy with a flattened head and small eyes, and the limbs are short. There are no parotoid glands and the skin is covered with small, rough tubercles. The colour is very variable, the upper side usually being some shade of olive, grey, charcoal, or muddy brown, sometimes mottled with ochre, with an intermittent yellowish stripe down the spine. The underside has a row of dark splotches at either side and the centre is red, orange, or yellow. The male has a rounded cloacal swel ...

Giuseppe Gené
Carlo Giuseppe Gené (7 December 1800 – 14 July 1847) was an Italian naturalist and author. Gené was born at Turbigo in Lombardy and studied at the University of Pavia. He published a number of papers on natural history, particularly entomology. In 1828 he became an assistant lecturer in natural history at the university, and in the following year he traveled to Hungary, returning with a collection of insect specimens. Between 1833 and 1838 he made four trips to Sardinia collecting insects. In 1830 Gené succeeded Franco Andrea Bonelli as professor of zoology and director of the Royal Zoological Museum at Turin. Most of his insect collection is in the Turin Museum of Natural History. Duplicates are in Museo Civico di Storia Naturale di Milano The Museo Civico di Storia Naturale di Milano (Milan Natural History Museum) is a museum in Milan, Italy. It was founded in 1838 when naturalist Giuseppe de Cristoforis donated his collections to the city. Its first director ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Corsica
Corsica ( , Upper , Southern ; it, Corsica; ; french: Corse ; lij, Còrsega; sc, Còssiga) is an island in the Mediterranean Sea and one of the 18 regions of France. It is the fourth-largest island in the Mediterranean and lies southeast of the French mainland, west of the Italian Peninsula and immediately north of the Italian island of Sardinia, which is the land mass nearest to it. A single chain of mountains makes up two-thirds of the island. , it had a population of 349,465. The island is a territorial collectivity of France. The regional capital is Ajaccio. Although the region is divided into two administrative departments, Haute-Corse and Corse-du-Sud, their respective regional and departmental territorial collectivities were merged on 1 January 2018 to form the single territorial collectivity of Corsica. As such, Corsica enjoys a greater degree of autonomy than other French regional collectivities; for example, the Corsican Assembly is permitted to exercise ...
