''Microlophus barringtonensis'' or the Santa Fe lava lizard is a species of lava lizard or a population of ''Microlophus albemarlensis''. It inhabits Santa Fe island Santa Fe Island (Spanish: ''Isla Santa Fe''), also called Barrington Island after admiral Samuel Barrington, is a small island of which lies in the centre of the Galápagos archipelago, to the south-east of Santa Cruz Island. Visitor access i ... in the Galápogos. It is the only lava lizard on Santa Fe. It is extremely common. Etymology ''barringtonensis'' refers to its range in Santa Fe island, formerly named Barrington Island. Classification It is debated whether the species is a population or not. Authors have claimed that the population is an entire other species along with '' M. jacobi'' and '' M. indefatigabilis.'' This view is not widely accepted.

Georg Baur
Georg Baur (1859–1898) was a German vertebrate paleontologist and Neo-Lamarckian who studied reptiles of the Galapagos Islands, particularly the Galápagos tortoises, in the 1890s. He is perhaps best known for his subsidence theory of the origin of the Galapagos Islands, where he postulated the islands were the remains of a former landmass, connected to South America via Cocos Island. Early life and education Baur was born in Weisswasser, Bohemia in 1859. He spent his early years Hohenheim near Stuttgart. As his father was a professor of forestry, Baur initially planned to study forestry where his father was a professor. However, while at university he became interested in the fields of geology, paleontology, and botany instead. Career Prior to his work on the Galapagos Islands, Baur was an assistant to Othniel Charles Marsh at Yale University from 1884 until 1890. Baur undertook an expedition to the Galápagos Islands in 1891, leaving New York on May 1, arriving in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microlophus
''Microlophus'' is a genus of tropidurid lizards native to South America. Around 20 species are recognized and 10 of these are endemic to the Galápagos Islands, where they are commonly known as lava lizardsBenavides E, Baum R, Snell HM, Snell HL, Sites JW Jr (2009)"Island Biogeography of Galápagos Lava Lizards (Tropiduridae: ''Microlophus''): Species Diversity and Colonization of the Archipelago". (.pdf) ''Evolution'' 63 (6): 1606–1626. (they are sometimes placed in ''Tropidurus'' instead). The remaining, which often are called Pacific iguanas, are found in the Andes and along the Pacific coasts of Chile, Peru, and Ecuador. The distribution of the lava lizards and their variations in shape, colour, and behaviour show the phenomenon of adaptive radiation so typical of the inhabitants of this archipelago. One species occurs on all the central and western islands, which were perhaps connected during periods of lower sea levels, while one species each occurs on six other more pe ...

Microlophus Albemarlensis
''Microlophus albemarlensis'', the Galápagos Lava lizard, also known as the Albemarle Lava lizard, is a species of Lava lizard. It is endemic to the Galápagos Islands, where it occurs on several islands in the western archipelago: the large islands Isabela, Santa Cruz, Fernandina, Santiago and Santa Fe, as well as several smaller islands: Seymour, Baltra, Plaza Sur, Daphne Major and Rábida. It is the most widespread of the Galápagos species of ''Microlophus'', the others only occurring on single islands. Some authors however, consider populations on Santiago, Santa Cruz, and Santa Fe (and associated small islands) to be distinct species (''M. jacobi'', ''M. indefatigabilis'' and ''M. barringtonensis'', respectively). The species is commonly attributed to the genus ''Microlophus'' but has been historically placed in the genus ''Tropidurus''. Description Galapagos lava lizards are generally small, ranging from 4-7 inches long. Males are around 6-7 inches long, while ...

Santa Fe Island
Santa Fe Island (Spanish: ''Isla Santa Fe''), also called Barrington Island after admiral Samuel Barrington, is a small island of which lies in the centre of the Galápagos archipelago, to the south-east of Santa Cruz Island. Visitor access is by a wet landing in Barrington Bay on the north-eastern side of the island. Environment Geologically, the island is one of the oldest of the archipelago; volcanic rocks of about 4 million years old have been found. The vegetation of the island is characterized by brush, palo santo trees and stands of a large subvariety of the Galápagos prickly pear cactus, ''Opuntia galapageia'' subvar. ''barringtonensis''. Santa Fe is home to two endemic species and two endemic subspecies: the Barrington land iguana (''Conolophus pallidus''), the Barrington leaf-toed gecko (''Phyllodactylus barringtonensis''), www.reptile-database.org. the Santa Fe marine iguana (''Amblyrhynchus cristatus trillmichi'') and the Santa Fe rice rat (''Aegialomys gal ...

Galápagos Islands
The Galápagos Islands (Spanish: , , ) are an archipelago of volcanic islands. They are distributed on each side of the equator in the Pacific Ocean, surrounding the centre of the Western Hemisphere, and are part of the Republic of Ecuador. Located west of continental Ecuador, the islands are known for their large number of endemic species that were studied by Charles Darwin during the second voyage of HMS ''Beagle''. His observations and collections contributed to the inception of Darwin's theory of evolution by means of natural selection. The Galápagos Islands and their surrounding waters form the Galápagos Province of Ecuador, the Galápagos National Park, and the Galápagos Marine Reserve. The principal language on the islands is Spanish. The islands have a population of slightly over 25,000. The first recorded visit to the islands happened by chance in 1535, when Fray Tomás de Berlanga, the Bishop of Panamá, was surprised to find this undiscovered land on a vo ...

Microlophus Jacobi
''Microlophus jacobii'', the Santiago lava lizard, is a species of lava lizard in the family Tropiduridae. They are endemic to the Galapagos islands of Santiago, Bartolomé, Rábida and a few islets. They are also the only lava lizards present on these islands. This species was formerly considered a subpopulation of the Galápagos lava lizard, but is now widely considered as a distinct species. Description Common year-round, these diurnal lizards inhabit rocky volcanic areas of their islands along with dry shrub and grassland. They usually spend the midday hours in the shade to avoid the heat. They spend the night beneath the soil, among rocks or the leaf litter. This species is known to feed on plant material such as leaves, fruit, and seeds, along with insects. They have native predators such as Thomas's racer and invasive threats that were introduced by humans such as black rats. To escape from these predators, Santiago lava lizards have been known to run and hide in cre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microlophus Indefatigabilis
The Santa Cruz lava lizard (''Microlophus indefatigabilis'') is a species of lava lizard endemic to the Galapagos island of Santa Cruz. Description They are identifiable by a brown body with scattered black and white blotches with a distinctive red and black throat and a black chest. Females have a more uniform brown body, a bright orange face, and a black mark at shoulder level. The species is able to shed its tail without mortal injury. The Sexual dimorphism Harems are kept, and are competed for by males using a pushup ritual to avoid physical injury. Males have a higher stamina and greater body size compared to the female. Distribution Endemic to Santa Cruz Island Santa Cruz Island ( Spanish: ''Isla Santa Cruz'', Chumash: ''Limuw'') is located off the southwestern coast of Ventura, California, United States. It is the largest island in California and largest of the eight islands in the Channel Islands ..., it is found within volcanic rock areas, dry shrublands ...

Endemic Fauna Of The Galápagos Islands
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reptiles Described In 1892
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 ...
