Rábida Island
Rábida Island (), is one of the Galápagos Islands. The island has also been known as Jervis Island named in honour of the 18th-century British admiral John Jervis. In Ecuador it is officially known as Isla Rábida. Wildlife In addition to flamingos and the bachelor sea lion colony, pelicans, white-cheeked pintails, boobies, and nine species of finch have been reported. The rich wildlife attracts a number of tourists cruises. In 1971 the Galápagos National Park Service successfully eradicated goats from Rábida. This introduced species upset the natural environment and led to the extinction of several native creatures including geckos, land iguanas, and rice rats. Conservation and Restoration During January 2011, invasive rodents were removed from the island by The Galápagos National Park, assisted by Island Conservation to benefit Galapagos penguins and '' Scalesia stewartii'' (a tree forming daisy and the plant equivalent of one of Darwin's finches Darwin's finch ...

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 ...

Darwin's Finches
Darwin's finches (also known as the Galápagos finches) are a group of about 18 species of passerine birds. They are well known for their remarkable diversity in beak form and function. They are often classified as the subfamily Geospizinae or tribe Geospizini. They belong to the tanager family and are not closely related to the true finches. The closest known relative of the Galápagos finches is the South American '' Tiaris obscurus''. They were first collected when the second voyage of the ''Beagle'' visited the Galápagos Islands, with Charles Darwin on board as a gentleman naturalist. Apart from the Cocos finch, which is from Cocos Island, the others are found only on the Galápagos Islands. The term "Darwin's finches" was first applied by Percy Lowe in 1936, and popularised in 1947 by David Lack in his book ''Darwin's Finches''. Lack based his analysis on the large collection of museum specimens collected by the 1905–06 Galápagos expedition of the California Academy ...

Volcanoes Of The Galápagos Islands
The Galápagos Islands are an isolated set of volcanoes, consisting of shield volcanoes and lava plateaus, located west of Ecuador. They are driven by the Galápagos hotspot, and are between 4.2 million and 700,000 years of age. The largest island, Isabela, consists of six coalesced shield volcanoes, each delineated by a large summit caldera. Española, the oldest island, and Fernandina, the youngest, are also shield volcanoes, as are most of the other islands in the chain. The Galápagos Islands are perched on a large lava plateau known as the Galápagos Platform, which creates a shallow-water depth of at the base of the islands, which stretch over a -long diameter. Since Charles Darwin's famous visit to the islands in 1835, over 60 recorded eruptions have occurred in the islands, from six different shield volcanoes. Of the 21 emergent volcanoes, 13 are considered active. The Galápagos are geologically young for such a big chain, and the pattern of their rift zones follows ...

Scalesia
''Scalesia'' is a genus in the family Asteraceae endemic to the Galapagos Islands. It contains fifteen species that grow as shrubs or trees. This is unusual, because tree species are uncommon in Asteraceae. The genus ''Scalesia'' resulted from a blunder by Arnott who named it in honour of "W. Scales Esq., Cawdor Castle, Elginshire" but discovered after publication that the name should have read 'Stables', after Scottish botanist, William Alexander Stables (1810–1890). All of the species have soft, pithy wood. ''Scalesia'' species have been called "the Darwin's finches of the plant world" because they show a similarly dramatic pattern of adaptive radiation. One of the largest and most widespread species is ''Scalesia pedunculata'' – a large tree which grows up to 15 to 20 metres tall, reaching maturity in a few years time. These trees typically grow in dense stands of the same species and age. They die around the same time, and then a new generation of seedlings grows up in ...

Galapagos Penguin
The Galápagos penguin (''Spheniscus mendiculus'') is a penguin endemic to the Galápagos Islands, Ecuador. It is the only penguin found north of the equator. Most inhabit Fernandina Island and the west coast of Isabela Island. The cool waters of the Humboldt and Cromwell Currents allow it to survive despite the tropical latitude. The Galápagos penguin is one of the banded penguins, the other species of which live mostly on the coasts of Africa and mainland South America. It is one of the smallest species of penguin in the world. Because of their warm environment, Galápagos penguins have developed techniques to stay cool. The feathers on their back, flippers, and head are black, and they have a white belly and a stripe looping from their eyes down to their neck and chin. Each penguin keeps only one mate, and breeds year-round. Their nests are typically in caves and crevices as protection against predators and the harsh environment. The Galápagos penguin has a lifespan of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Island Conservation
Island Conservation is a non-profit organization with the mission to prevent extinctions by removing invasive species from islands. Island Conservation has therefore focused its efforts on islands with species categorized as Critically Endangered and Endangered on the IUCN's Red List. Working in partnership with local communities, government management agencies, and conservation organizations, Island Conservation develops plans and implements the removal of invasive alien species, and conducts field research to document the benefits of the work and to inform future projects. Island Conservation's approach is now being shown to have a wider beneficial effect on the marine systems surrounding its project areas. In addition, invasive vertebrate eradication has now been shown to have many benefits besides conservation of species. Specifically, the approach has been found to align with 13 UN Sustainable Development Goals and 42 associated targets encompassing marine and terrestrial ...

Galápagos National Park
Galápagos National Park ( es, Parque Nacional Galápagos) was established in 1959. It began operation in 1968, and it is Ecuador's first national park and a UNESCO World Heritage Site. Park history The government of Ecuador has designated 97% of the land area of the Galápagos Islands as the country's first national park. The remaining 3% is distributed between the inhabited areas of Santa Cruz, San Cristóbal, Baltra, Floreana and Isabela. In 1971, the Galápagos National Park Service had its first Superintendent, 2 officers and 6 park rangers on Santa Cruz Island. In 1974, the Galápagos National Park Service had its first management plan and a team of officials in accordance with the organic structure issued in 1973, with a Superintendent, 2 conservation officers, 40 park rangers to comply with management objectives. On Santa Cruz is the Charles Darwin Research Station. In 1979 UNESCO declared the Galápagos Islands Natural Heritage for Humanity, making the Park Se ...

Galapagos Land Iguana
The Galápagos land iguana (''Conolophus subcristatus'') is a very large species of lizard in the family Iguanidae. It is one of three species of the genus ''Conolophus''. It is endemic to the Galápagos Islands, in the dry lowlands of the islands of Fernandina, Isabela, Santa Cruz, North Seymour, Baltra, and South Plaza. Taxonomy The land iguanas in the Galápagos vary in morphology and coloration among different populations. In addition to the relatively widespread and well-known Galápagos land iguana (''C. subcristatus''), there are two other species of ''Conolophus'': the Galápagos pink land iguana (''C. marthae'') from northern Isabela Island and the Santa Fe land iguana (''C. pallidus'') from Santa Fe Island. Based on mtDNA, land iguanas and marine iguanas diverged about 8–10 million years ago. Within the land iguana genus, the oldest split based on mtDNA, about 5.7 million years old, is between ''C. subcristatus'' and ''C. marthae''. A more recent study that ...

Phyllodactylus
''Phyllodactylus'' is a genus of geckos distributed in South America and Central America, and as far north as the southern United States. They are commonly known as " leaf-toed geckos" in their native range, and otherwise as American leaf-toed geckos to distinguish them from unrelated genera with similar feet. Species ''Phyllodactylus'' contains these species: *'' Phyllodactylus andysabini'' Arteaga, Bustamante, Vieira, Tapia & Guayasamin, 2019 – Andy Sabin's leaf-toed gecko, Wolf Volcano leaf-toed gecko *'' Phyllodactylus angustidigitus'' Dixon & Huey, 1970 – narrow leaf-toed gecko *'' Phyllodactylus apricus'' Dixon, 1966 – Las Animas Island gecko *'' Phyllodactylus barringtonensis'' Van Denburgh, 1912 – Barrington leaf-toed gecko *''Phyllodactylus baurii'' Garman, 1892 – Baur's leaf-toed gecko *'' Phyllodactylus benedettii'' Ramírez-Reyes & Flores-Villela, 2018 *'' Phyllodactylus bordai'' Taylor, 1942 – Guerreran leaf-toed gecko *'' Phyllodactylus bugastr ...

Booby
A booby is a seabird in the genus ''Sula'', part of the family Sulidae. Boobies are closely related to the gannets (''Morus''), which were formerly included in ''Sula''. Systematics and evolution The genus ''Sula'' was introduced by the French zoologist Mathurin Jacques Brisson in 1760. The type species is the brown booby. The name is derived from ''súla'', the Old Norse and Icelandic word for the other member of the family Sulidae, the gannet. The English name "booby" was possibly based on the Spanish slang term ''bobo'', meaning "stupid", as these tame birds had a habit of landing on board sailing ships, where they were easily captured and eaten. Owing to this, boobies are often mentioned as having been caught and eaten by shipwrecked sailors, notably William Bligh of the ''Bounty'' and his adherents during their famous voyage after being set adrift by Fletcher Christian and his followers. Six of the ten extant Sulidae species called ''boobies'' are in the genus ''Sul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
