Microlophus Bivittatus
''Microlophus bivittatus'', the San Cristóbal lava lizard, is a species of lava lizard endemic to San Cristóbal Island in the Galápagos Islands. The species is commonly attributed to the genus ''Microlophus'' but has been attributed to the genus ''Tropidurus''. They are currently under threat by invasive cats on the island. The lizard is also closely related to the Microlophus occipitalis ''Microlophus occipitalis'', colloquially known as the knobbed Pacific iguana, is a lizard included within the Tropiduridae family. It is a member of the ''Microlophus'' genus and thus also considered a lava lizard. The knobbed Pacific iguana i ... which radiated off of the bivittatus. Reproduction Lava lizards have a breeding ritual where males will compete via head bobbing to avoid physical conflict. Research has found that head bobbing achieves a greater response when the response is immediate as compared to a 30-second delay. Larger males will receive greater aggression from other ...

Wilhelm Peters
Wilhelm Karl Hartwich (or Hartwig) Peters (22 April 1815 in Koldenbüttel – 20 April 1883) was a German natural history, naturalist and explorer. He was assistant to the anatomist Johannes Peter Müller and later became curator of the Natural History Museum, Berlin, Berlin Zoological Museum. Encouraged by Müller and the explorer Alexander von Humboldt, Peters travelled to Mozambique via Angola in September 1842, exploring the coastal region and the Zambesi River. He returned to Berlin with an enormous collection of natural history specimens, which he then described in ''Naturwissenschaftliche Reise nach Mossambique... in den Jahren 1842 bis 1848 ausgeführt'' (1852–1882). The work was comprehensive in its coverage, dealing with mammals, birds, reptiles, amphibians, river fish, insects and botany. He replaced Martin Lichtenstein as curator of the museum in 1858, and in the same year he was elected a foreign member of the Royal Swedish Academy of Sciences. In a few years, he g ...

Lava Lizard
''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 ...

Endemism
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] |
San Cristóbal Island
San Cristóbal Island ( es, Isla San Cristóbal) and named previously by the English as ''Chatham Island'', is the easternmost island in the Galápagos archipelago, as well as one of the oldest geologically. It is administratively part of San Cristóbal Canton, Ecuador. Its Spanish (and official Ecuadorian) name "San Cristóbal" comes from the patron saint of seafarers, St. Christopher. English speakers increasingly use that name in preference to the traditional English name of Chatham Island, derived from William Pitt, 1st Earl of Chatham. History San Cristobal Island is composed of three or four fused volcanoes, all extinct. It is home to the oldest permanent settlement of the islands and is the island where Darwin first went ashore in 1835. A small lake called El Junco is the only source of fresh water in the islands. The availability of fresh water is what led to the early settlement of San Cristobal. A penal colony was built on San Cristóbal Island in 1880 ...

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 ...

Tropidurus
''Tropidurus'' is a genus of reptiles. The genus includes many species of Neotropical ground lizards (family Tropiduridae). ''Tropidurus'' is the type genus of the family Tropiduridae. Geographic range and habitat Species in the genus ''Tropidurus'' are found on the South American mainland, especially in the Amazon Rainforest, but also in more arid regions. Common name No widely common name is used solely for species of the genus ''Tropidurus''. In their native range, they are simply called "Lagartixa" as are most similar animals. If anything, the Brazilian term ''calango'' is used to particularly refer to lizards of the genus ''Tropidurus''. Taxonomy The genus ''Tropidurus'' contains 30 described species, but new ones continue to be discovered. An additional seven species—the Galápagos lava lizards endemic to the Galápagos Islands—are sometimes placed here, too, but more commonly separated in the genus ''Microlophus'', instead. Similarly, the green thornytail ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microlophus Occipitalis
''Microlophus occipitalis'', colloquially known as the knobbed Pacific iguana, is a lizard included within the Tropiduridae family. It is a member of the ''Microlophus'' genus and thus also considered a lava lizard. The knobbed Pacific iguana is found primarily in Western Peru and Ecuador, lining the coasts. The habitats of the knobbed Pacific iguana can be considered to be both broad and diverse as they are typically found in many different places such as beaches, lomas, and all the way to desert regions. This diversity is furthered as these lizards can also be found in open areas, between rocks, or bushes. The knobbed Pacific iguana displays distinct sexual dimorphism as seen by the different sizes and appearances of the male and females. Males are significantly larger and as a whole species, knobbed Pacific iguanas can range from in snout-vent length. The two sexes also possess different coloration with males most often lacking color and females having a range of red to wh ...

Lizards Of South America
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 ...

Reptiles Of Ecuador
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 ...
