Pholidoscelis Pluvianotatus
The Montserrat ameiva (''Pholidoscelis pluvianotatus'') is a lizard species in the genus ''Pholidoscelis''. It is found on the Caribbean island of Montserrat in the Lesser Antilles. Description The species is variable in color and pattern. The dorsal surface on males is reddish or gray-tan, with black speckling and lighter marbling; or it is dull green with slight markings and a dark blue head. The male's ventral surface is dull gray, and it has blue-gray spots on its upper thighs and sides of its tail. Females have a gray dorsal surface and a bluish underside. It is covered with light, widespread spots on its back, sides, legs, and tail. The flanks on females are dull green, sometimes with brown stripes present. Taxonomy The Montserrat ameiva was described in 1887 by American herpetologist Samuel Garman (1843–1927) as ''Ameiva pluvianotata''. In 2016, the species was moved to ''Pholidoscelis'' based on genetic sequencing and phylogenetic analyses. The Redonda ground lizard i ...

Samuel Garman
Samuel Walton Garman (June 5, 1843 – September 30, 1927), or "Garmann" as he sometimes styled himself, was a naturalist/zoologist from Pennsylvania. He became noted as an ichthyologist and herpetologist. Biography Garman was born in Indiana County, Pennsylvania, on 5 June 1843. In 1868 he joined an expedition to the American West with John Wesley Powell. He graduated from the Illinois State Normal University in 1870, and for the following year was principal of the Mississippi State Normal School. In 1871, he became professor of natural sciences in Ferry Hall Seminary, Lake Forest, Illinois, and a year later became a special pupil of Louis Agassiz. He was a friend and regular correspondent of the naturalist Edward Drinker Cope, and in 1872 accompanied him on a fossil hunting trip to Wyoming. In 1870 he became assistant director of herpetology and ichthyology at Harvard's Museum of Comparative Zoology. His work was mostly in the classification of fish, especially sharks, ...

Antigua And Barbuda
Antigua and Barbuda (, ) is a sovereign country in the West Indies. It lies at the juncture of the Caribbean Sea and the Atlantic Ocean in the Leeward Islands part of the Lesser Antilles, at 17°N latitude. The country consists of two major islands, Antigua and Barbuda, approximately apart, and several smaller islands, including Great Bird, Green, Guiana, Long, Maiden, Prickly Pear, York, and Redonda. The permanent population is approximately 97,120 ( est.), 97% residing in Antigua. St. John's, Antigua, is the country's capital, major city, and largest port. Codrington is Barbuda's largest town. In 1493, Christopher Columbus reconnoitred the island of Antigua, which he named for the Church of Santa María La Antigua.Crocker, John. "Barbuda Eyes Statehood and Tourists".

Reptiles Described In 1887
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 around 31 ...

Endemic Fauna Of Montserrat
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat Destruction
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...

Censky's Ameiva
Censky's ameiva (''Pholidoscelis corax''), also known as the Little Scrub Island ground lizard, is a species of lizard in the family Teiidae. It is indigenous to the Caribbean. Description ''P. corax'' is a melanistic species, superficially similar in its dark coloration and scalation to '' Pholidoscelis atratus'' and '' Pholidoscelis corvinus'', other species also found on small, barren Caribbean islands. This is believed to be due to independent adaptation to the similar local environments. Taxonomy Censky's ameiva was described in 1992 as ''Ameiva corax''.Censky EJ, Paulson DR (1992). "Revision of ''Ameiva'' (Reptilia: Teiidae) of the Anguilla Bank, West Indies". ''Ann. Carnegie Mus.'' 61: 177-195. (''Ameiva corax'', new species, p. 187).

Sombrero Ameiva
The Sombrero ameiva (''Pholidoscelis corvinus'') is a lizard species in the genus ''Ameiva''. It is endemic to Sombrero, a small, uninhabited island in the Lesser Antilles under the jurisdiction of Anguilla. Description Adults are melanistic, appearing plain brown to slate black, with a dark green to black ventral surface mottled with light blue. Its tail is sometimes spotted green. Males have brown flecks on the dorsal surface and browner heads. Males grow to 133 mm snout-to-vent length, with females being considerably smaller. It is superficially similar in coloration and scalation to ''Pholidoscelis atratus'' and '' Pholidoscelis corax'', two other melanistic species also found on small, barren islands in the Caribbean. As both islands have similar habitats, this is likely the result of independent adaptation. Its diet includes the eggs of ground-nesting birds. Conservation The Sombrero ameiva is listed as critically endangered on the IUCN Red List due to its limited di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Redonda
Redonda is an uninhabited Caribbean island that is a part of Antigua and Barbuda, in the Leeward Islands, West Indies. The island is about long, wide, and is high at its highest point. This small island lies between the islands of Nevis and Montserrat, southwest of Antigua. Redonda is closer to Montserrat than to any other island; it is located at northwest of Montserrat, and southeast of Nevis. Redonda is home to vast numbers of sea birds, and the island was an important source of guano before artificial fertilisers started to be mass-produced. Guano-mining operations started in the 1860s and ceased after the start of World War I. During these mining operations a few buildings and other installations were put in place on the island, and some physical remnants of that phase in its history are still visible. "Redonda" is the female form of the Spanish language adjective meaning "round". In 1493, on his second voyage to the New World, Christopher Columbus discovered the isl ...
