Anolis Pulchellus
''Anolis pulchellus'', the Puerto Rican bush anole, snake anole, or Puerto Rican anole, is a small anole lizard of the family Dactyloidae. The species is among the most common lizards in Puerto Rico, and also native to Vieques, Culebra, and the Virgin Islands (except St. Croix). The sharp-mouthed lizard measures approximately in length from snout to vent. The species has a yellow-brown color with males having a purple dewlap that blends into crimson near the tip. The anoles of the Greater Antilles have been extensively studied since they represent an interesting case of adaptive radiation. Species are more closely related to other species within the same island than to species of adjacent islands. Even though species divergence occurred independently on each island, the same set of ecomorphs (habitat specialists) have evolved on each island. ''Anolis pulchellus'' is considered a grass-bush anole, occurring primarily in bushes or grass. See also *Fauna of Puerto Rico *List o ...

IUCN
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Reptiles Described In 1837
Reptiles, as most commonly defined are the animals in the class Reptilia ( ), a paraphyletic grouping comprising all sauropsids except birds. Living reptiles comprise turtles, crocodilians, squamates ( lizards and snakes) and rhynchocephalians (tuatara). As of March 2022, the Reptile Database includes about 11,700 species. In the traditional Linnaean classification system, birds are considered a separate class to reptiles. However, crocodilians are more closely related to birds than they are to other living reptiles, and so modern cladistic classification systems include birds within Reptilia, redefining the term as a clade. Other cladistic definitions abandon the term reptile altogether in favor of the clade Sauropsida, which refers to all amniotes more closely related to modern reptiles than to mammals. The study of the traditional reptile orders, historically combined with that of modern amphibians, is called herpetology. The earliest known proto-reptiles originated a ...

Fauna Of Puerto Rico
The fauna of Puerto Rico is similar to other island archipelago faunas, with high endemism, and low, skewed taxonomic diversity. Bats are the only extant native terrestrial mammals in Puerto Rico. All other terrestrial mammals in the area were introduced by humans, and include species such as cats, goats, sheep, the small Indian mongoose, and escaped monkeys. Marine mammals include dolphins, manatees, and whales. Of the 349 bird species, about 120 breed in the archipelago, and 47.5% are accidental or rare. The most recognizable and famous animal of Puerto Rico is probably the common coquí, a small endemic frog, and one of the 86 species that constitute Puerto Rico's herpetofauna. Some native freshwater fish inhabit Puerto Rico, but some species, introduced by humans, have established populations in reservoirs and rivers. The low richness-high diversity pattern is also apparent among invertebrates, which constitutes most of the archipelago's fauna. The arrival of the first peo ...

Anolis Ecomorph
The ecomorph concept is a term first coined by Ernest Edward Williams in 1972 which he defined as a “species with the same structural habitat/niche, similar in morphology and behavior, but not necessarily close phyletically.” Williams first applied this definition to the Greater Antillean anoles (especifically in Puerto Rico) upon observing their evolutionary radiation, although it has since been used widely elsewhere. Anoles have repeatedly evolved into similar forms on different islands, dubbed 'ecomorphs'. Convergence is in microhabitat specialty, behavior, and morphology. Langerhans, Knouft & Losos call the set of ''Anolis'' lizard ecomorphs of the Greater Antilles "a classic example of convergent evolution."''Topic: Anolis lizard ecomorphs''. Map of Life: Conver ...

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 ...

Dewlap
A dewlap is a longitudinal flap of skin or similar flesh that hangs beneath the lower jaw or neck of many vertebrates. More loosely, it can be various similar structures in the neck area, such as those caused by a double chin or the submandibular vocal sac of a frog. More generally, it can be any hanging mass of skin, such as a fold of loose skin on an elderly person's neck, or the wattle of a bird. Dewlaps can be considered as a ''caruncle'', defined as "a small, fleshy excrescence that is a normal part of an animal's anatomy". Etymology The word is first attested in the mid 1300s as ''dewelappe'' ("fold of skin that hangs from the throat of oxen and kine"), from ''lappe'' ("loose piece", from Old English ), but the first element ''*dew(e)-'' is of nebulous origin and meaning; it probably was altered by folk etymology with "dew". Old English had ''fræt-læppa'' in the aforementioned sense (and Middle English ''fresh-lappe''). There also seems to be a cognate to Danish dial ...

André Marie Constant Duméril
André Marie Constant Duméril (1 January 1774 – 14 August 1860) was a French zoologist. He was professor of anatomy at the Muséum national d'histoire naturelle from 1801 to 1812, when he became professor of herpetology and ichthyology. His son Auguste Duméril was also a zoologist. Life André Marie Constant Duméril was born on 1 January 1774 in Amiens and died on 14 August 1860 in Paris. He became a doctor at a young age, obtaining, at 19 years, the ''prévot'' of anatomy at the medical school of Rouen. In 1800, he left for Paris and collaborated in the drafting of the comparative anatomy lessons of Georges Cuvier. He replaced Cuvier at the Central School of the Panthéon and had, as his colleague, Alexandre Brongniart. In 1801, he gave courses to the medical school of Paris. Under the ''Restauration'', he was elected a member of the Académie des Sciences (French Academy of Sciences) and after 1803 succeeded Lacépède, who was occupied by his political offic ...

Cloaca
In animal anatomy, a cloaca ( ), plural cloacae ( or ), is the posterior orifice that serves as the only opening for the digestive, reproductive, and urinary tracts (if present) of many vertebrate animals. All amphibians, reptiles and birds, and a few mammals ( monotremes, tenrecs, golden moles, and marsupial moles), have this orifice, from which they excrete both urine and feces; this is in contrast to most placental mammals, which have two or three separate orifices for evacuation. Excretory openings with analogous purpose in some invertebrates are also sometimes referred to as cloacae. Mating through the cloaca is known as cloacal copulation, commonly referred to as cloacal kiss. The cloacal region is also often associated with a secretory organ, the cloacal gland, which has been implicated in the scent-marking behavior of some reptiles, marsupials, amphibians, and monotremes. Etymology The word is from the Latin verb ''cluo'', "(I) cleanse", thus the noun ''cloaca'', ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
