Anolis
''Anolis'' is a genus of anoles (), iguanian lizards in the family Dactyloidae, native to the Americas. With more than 425 species, it represents the world's most species-rich amniote tetrapod genus, although many of these have been proposed to be moved to other genera, in which case only about 45 ''Anolis'' species remain. Previously, it was classified under the family Polychrotidae that contained all the anoles, as well as ''Polychrus'', but recent studies place it in the Dactyloidae. Taxonomy This very large genus displays considerable paraphyly, but phylogenetic analysis suggests a number of subgroups or clades. Whether these clades are best recognized as subgenera within ''Anolis'' or separate genera remains a matter of dispute. If the clades are recognized as full genera, about 45 species remain in ''Anolis'', with the remaining moved to ''Audantia'' (9 species), ''Chamaelinorops'' (7 species), ''Ctenonotus'' (more than 40 species), ''Dactyloa'' (''circa'' 95 species), ...

Dactyloidae
Dactyloidae are a family of lizards commonly known as anoles () and native to warmer parts of the Americas, ranging from southeastern United States to Paraguay. Instead of treating it as a family, some authorities prefer to treat it as a subfamily, Dactyloidae, of the family Iguanidae. In the past they were included in the family Polychrotidae together with ''Polychrus'' (bush anoles), but the latter genus is not closely related to the true anoles. Anoles are small to fairly large lizards, typically green or brownish, but their color varies depending on species and many can also change it. In most species at least the male has a dewlap, an often brightly colored flap of skin that extends from the throat/neck and is used in displays. Anoles share several characteristics with geckos, including details of the foot structure (for climbing) and the ability to voluntarily break off the tail (to escape predators), but they are only very distantly related, anoles being part of Iguania. ...

Anolis Carolinensis
''Anolis carolinensis'' or green anole () (among other names below) is a tree-dwelling species of anole lizard native to the southeastern United States and introduced to islands in the Pacific and Caribbean. A small to medium-sized lizard, the green anole is a trunk-crown ecomorph and can change its color to several shades from brown to green. Other common names include the Carolina anole, Carolina green anole, American anole, American green anole, North American green anole and red-throated anole. It is sometimes referred to as the American chameleon (typically in the pet trade) due to its color-changing ability; however, it is not a true chameleon. Description The green anole is a small to medium-sized lizard, with a slender body. The head is long and pointed with ridges between the eyes and nostrils, and smaller ones on the top of the head. The toes have adhesive pads to facilitate climbing. They exhibit sexual dimorphism, the males being fifteen percent larger. Adult ma ...

Carolinensis
The ''Anolis carolinensis'' series is a proposed clade or subgroup of closely related mid-sized trunk crown anoles () within the genus ''Anolis''. It was created by Nicholson ''et al''. in 2012 and defined as containing 13 species, a few examples are listed below. List of ''A. carolinensis'' clade species * ''Anolis allisoni'' – Allison's anole * '' Anolis altitudinalis'' * ''Anolis brunneus'' * ''Anolis carolinensis'' – Carolina anole, American green anole * '' Anolis fairchildi'' * '' Anolis incredulus'' * '' Anolis isolepis'' * '' Anolis longiceps'' * ''Anolis maynardi'' * '' Anolis oporinus'' * ''Anolis porcatus'' – Cuban green anole * '' Anolis smaragdinus'' – Bahamian green anole * '' Anolis toldo'' Origin Many species of the carolinensis subgroup are remarkably obscure and, with the exception of a few species such as '' A.carolinensis'', very little is known about its members or its origin. However, it is believed that the clade originated on Cuba (Glor 2005), ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adaptive Radiation
In evolutionary biology, adaptive radiation is a process in which organisms diversify rapidly from an ancestral species into a multitude of new forms, particularly when a change in the environment makes new resources available, alters biotic interactions or opens new environmental niches. Starting with a single ancestor, this process results in the speciation and phenotypic adaptation of an array of species exhibiting different morphological and physiological traits. The prototypical example of adaptive radiation is finch speciation on the Galapagos ("Darwin's finches"), but examples are known from around the world. Characteristics Four features can be used to identify an adaptive radiation: #A common ancestry of component species: specifically a ''recent'' ancestry. Note that this is not the same as a monophyly in which ''all'' descendants of a common ancestor are included. #A phenotype-environment correlation: a ''significant'' association between environments and the morp ...

Iguania
Iguania is an infraorder of squamate reptiles that includes iguanas, chameleons, agamids, and New World lizards like anoles and phrynosomatids. Using morphological features as a guide to evolutionary relationships, the Iguania are believed to form the sister group to the remainder of the Squamata, which comprise nearly 11,000 named species, roughly 2000 of which are iguanians. However, molecular information has placed Iguania well within the Squamata as sister taxa to the Anguimorpha and closely related to snakes. The order has been under debate and revisions after being classified by Charles Lewis Camp in 1923 due to difficulties finding adequate synapomorphic morphological characteristics. Most Iguanias are arboreal but there are several terrestrial groups. They usually have primitive fleshy, non-prehensile tongues, although the tongue is highly modified in chameleons. The group has a fossil record that extends back to the Early Jurassic (the oldest known member is '' B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lizard Genera
Lizards are a widespread group of squamate reptiles, with over 7,000 species, ranging across all continents except Antarctica, as well as most oceanic island chains. The group is paraphyletic since it excludes the snakes and Amphisbaenia although some lizards are more closely related to these two excluded groups than they are to other lizards. Lizards range in size from chameleons and geckos a few centimeters long to the 3-meter-long Komodo dragon. Most lizards are quadrupedal, running with a strong side-to-side motion. Some lineages (known as "legless lizards"), have secondarily lost their legs, and have long snake-like bodies. Some such as the forest-dwelling ''Draco'' lizards are able to glide. They are often territorial, the males fighting off other males and signalling, often with bright colours, to attract mates and to intimidate rivals. Lizards are mainly carnivorous, often being sit-and-wait predators; many smaller species eat insects, while the Komodo eats mammals as bi ...

François Marie Daudin
François Marie Daudin (; 29 August 1776 in Paris – 30 November 1803 in Paris) was a French zoologist. With legs paralyzed by childhood disease, he studied physics and natural history, but ended up being devoted to the latter. Daudin wrote ' (Complete and Elementary Treatise of Ornithology) in 1799–1800. It was one of the first modern handbooks of ornithology, combining Linnean binomial nomenclature with the anatomical and physiological descriptions of Buffon. While an excellent beginning, it was never completed. In 1800, he also published ''Recueil de mémoires et de notes sur des espèces inédites ou peu connues de mollusques, de vers et de zoophytes'' (Collection of memories and notes on new or little-known species of molluscs, worms and zoophytes). Daudin found his greatest success in herpetology. He published ''Histoire naturelle des reinettes, des grenouilles et des crapauds'' (Natural history of tree frogs, frogs and toads) in 1802, and ''Histoire naturelle, gé ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Greater Antilles
The Greater Antilles ( es, Grandes Antillas or Antillas Mayores; french: Grandes Antilles; ht, Gwo Zantiy; jam, Grieta hAntiliiz) is a grouping of the larger islands in the Caribbean Sea, including Cuba, Hispaniola, Puerto Rico, Jamaica, and the Cayman Islands. Six island states share the region of the Greater Antilles, with Haiti and the Dominican Republic sharing the island of Hispaniola. Together with the Lesser Antilles, they make up the Antilles. While most of the Greater Antilles consists of independent countries, Puerto Rico is an unincorporated territory of the United States, while the Cayman Islands are a British Overseas Territory. The largest island by area is Cuba, which extends to the western end of the island group. Puerto Rico lies on the eastern end, and the island of Hispaniola, the largest island by population, is located in the middle. Jamaica lies to the south of Cuba, while the Cayman Islands are located to the west. The state of Florida is the closes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
