Lissotriton Lantzi
''Lissotriton'' is a genus of newts native to Europe and parts of Asia Minor. As most other newts, they are aquatic as larvae and during breeding time but live in terrestrial, humid environments over the rest of the season. These rather small species used to be included in genus ''Triturus'', but phylogenetic analyses demonstrated that genus as paraphyletic. In the following, the name ''Lissotriton'', originally introduced by Thomas Bell in 1839, was reinstated for the small-bodied species related to the type species ''Lissotriton vulgaris'' (the smooth newt). Their exact phylogenetic placement within the newts (subfamily Pleurodelinae) is still uncertain. Species Currently, ten species are listed in ''Amphibian Species of the World'' – the rank of some of these as species or subspecies is however controversial: *''Lissotriton boscai'' (Lataste, 1879) – Bosca's newt *''Lissotriton graecus'' (Wolterstorff, 1906) – Greek newt *''Lissotriton helveticus'' (Razoumovsky, 1789) ...

Lissotriton Italicus
The Italian newt (''Lissotriton italicus'') is a species of salamander in the family Salamandridae found only in Italy. The species can be found in temperate forests, temperate shrubland, Mediterranean-type shrubby vegetation, freshwater lakes, intermittent freshwater lakes, freshwater marshes, intermittent freshwater marshes, arable land, pastureland, rural gardens, water storage areas, ponds, and canals and ditches. It is threatened by habitat loss, natural land conversion and invasive species An invasive species otherwise known as an alien is an introduced organism that becomes overpopulated and harms its new environment. Although most introduced species are neutral or beneficial with respect to other species, invasive species ad .... It was formerly known as ''Triturus italicus'', but was relocated to the genus ''Lissotriton'' after ''Triturus'' was split. Population The Italian newt is more common in southern areas, and rarer in the northern parts of Italy. Refere ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Inbreeding Depression
Inbreeding depression is the reduced biological fitness which has the potential to result from inbreeding (the breeding of related individuals). Biological fitness refers to an organism's ability to survive and perpetuate its genetic material. Inbreeding depression is often the result of a population bottleneck. In general, the higher the genetic variation or gene pool within a breeding population, the less likely it is to suffer from inbreeding depression, though inbreeding and outbreeding depression can simultaneously occur. Inbreeding depression seems to be present in most groups of organisms, but varies across mating systems. Hermaphroditic species often exhibit lower degrees of inbreeding depression than outcrossing species, as repeated generations of selfing is thought to purge deleterious alleles from populations. For example, the outcrossing nematode (roundworm) ''Caenorhabditis remanei'' has been demonstrated to suffer severely from inbreeding depression, unlike its he ...

Mate Choice
Mate choice is one of the primary mechanisms under which evolution can occur. It is characterized by a "selective response by animals to particular stimuli" which can be observed as behavior.Bateson, Paul Patrick Gordon. "Mate Choice." Mate Choice, Cambridge University Press, 1985 In other words, before an animal engages with a potential mate, they first evaluate various aspects of that mate which are indicative of quality—such as the resources or phenotypes they have—and evaluate whether or not those particular Phenotypic trait, trait(s) are somehow beneficial to them. The evaluation will then incur a response of some sort. These mechanisms are a part of evolutionary change because they operate in a way that causes the qualities that are desired in a mate to be more frequently passed on to each generation over time. For example, if female peacocks desire mates who have a colourful plumage, then this trait will increase in frequency over time as male peacocks with a colourful ...

Lissotriton Schmidtleri
Schmidtler's smooth newt (''Lissotriton schmidtleri'') is a newt species found from northwestern Greece and southeast Bulgaria over East Thrace across the Bosphorus to northwest Anatolia. Its range borders that of the smooth newt (''L. vulgaris''), the Greek smooth newt (''L. graecus'') and Kosswig's smooth newt (''L. kosswigi'') to the north, west, and east, respectively. Christopher Raxworthy described the species in 1988 as ''Triturus vulgaris schmidtleri'', a subspecies of the smooth newt. After genetic data had suggested the smooth newt was a complex of distinct lineages, Pabijan and colleagues recognised Schmidtler's smooth newt as distinct species in 2017. This was followed by subsequent authors. The species differs from other species in the smooth newt species complex mainly in the male secondary characters during breeding season. It is overall very similar to the smooth newt but rather small, with males reaching length. The dorsal crest reaches 2 mm or more i ...

Lissotriton Montandoni
The Carpathian newt, or Montandon’s newt, (''Lissotriton montandoni'') is a species of salamander in the family Salamandridae found in Czech Republic, Poland, Romania, Slovakia, and Ukraine. The total length of adults of this species is around 10 cm. Its natural habitats are temperate forests, rivers, intermittent rivers, freshwater marshes, intermittent freshwater marshes, arable land, pastureland, rural gardens, and ponds. It is threatened by habitat loss. Description The Carpathian newt grows to a total length of about , females in general being larger than males. The skin is granulated in terrestrial individuals but smoother in more aquatic ones. There are three grooves on the head and the body is very square in cross section. The upper surface is yellowish-brown or olive-brown, copiously mottled with fine dark spots. The underparts are yellow or orange, often with small black spots at the sides. The lower part of the tail is white or orange with large black spots. In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lissotriton Helveticus
The palmate newt (''Lissotriton helveticus'') is a species of newt found in Western Europe, from Great Britain to the northern Iberian peninsula. It is long and olive or brown with some dark spots. The underside is yellow to orange, and the throat, unlike in the similar smooth newt, always unspotted. A dark stripe runs along the head and through the eyes. Breeding males develop a distinct filament on the end of their tail, strongly webbed hind feet, and a low, smooth crest on their back. Habitats include forests, marshes, pastures or gardens. While on land, the newts are mainly nocturnal. After emerging from hibernation in spring, they move to stagnant, fish-free water bodies for breeding. After a courtship display, the male deposits a spermatophore that is picked up by the female. Larvae develop over after 1.5–3.5 months before metamorphosing into land-dwelling juveniles (efts). Sexual maturity is reached after two to three years, and the newts can reach a total age of up t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Thomas Hornsey Bell FRS FLS (11 October 1792 – 13 March 1880) was an English zoologist, dental surgeon A dentist, also known as a dental surgeon, is a health care professional who specializes in dentistry (the diagnosis, prevention, management, and treatment of diseases and conditions of the oral cavity and other aspects of the craniofacial com ... and writer, born in Poole, Dorset, England. Career Bell, like his mother Susan, took a keen interest in natural history which his mother also encouraged in his younger cousin Philip Henry Gosse. Bell left Poole in 1813 for his training as a dental surgeon in London. He is listed in 1817 as having an address at number 17 Fenchurch Street, and as being a committee member of the newly formed London Peace Society. By 1819 his address is given as 18 Bucklersbury, also in the city of London. He combined two careers, becoming Professor of Zoology at King's College London in 1836 (on the strength of amateur research) and lecturing o ...
