Phelsuma Gigas
The Rodrigues giant day gecko (''Phelsuma gigas'') is an extinct species of day gecko. It lived on the island of Rodrigues (island), Rodrigues and surrounding islands and typically dwelt on trees. The Rodrigues giant day gecko fed on insects and nectar, and, unlike most other day geckos, was apparently nocturnal in habit. Description ''Phelsuma gigas'' was one of the largest known geckoes. It reached a total length of about . The body colour was grayish or grayish brown. On the back there were irregular black spottings. The tail had some striping and was charcoal- or dark grey-coloured. The tongue had a pink colour and the ventral side of the body was light yellow. The original collected specimens that were used to describe this species have been lost. Today, only a few portions of some skeletons remain. Behaviour Leguat described the species: Distribution This species inhabited Rodrigues (island), Rodrigues and surrounding islands. ''P. gigas'' was last collected in 1842 on t ...

François Liénard De La Mivoye
François Liénard de la Mivoye (born 29 July 1782, Visakhapatnam, died 6 November 1862, Paris) was a Francophone Mauritian naturalist, ichthyologist, zoologist and mariner. He lived most of his life in Mauritius and, in 1829, was a founder member and treasurer of the ''société d'histoire natural locale'' alongside Charles Telfair, Wenceslas Bojer, Jacques Delisse and Julien Desjardins. In 1841 this became the ''Société Royale des arts et des Sciences de l'île Maurice''. The Society regularly sent fish specimens to Georges Cuvier in Paris and these were Species description, described in his 22 volume ''Histoire naturelle des poissons'', this was completed after Cuvier’s death by Achille Valenciennes. Liénard was responsible for describing a number of species including the now extinct Rodrigues giant day gecko (''Phesulma gigas''), Liénard being the last known person to see this species. Liénard is commemorated in the Specific name (zoology), specific name of the predatory ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Albert Günther
Albert Karl Ludwig Gotthilf Günther FRS, also Albert Charles Lewis Gotthilf Günther (3 October 1830 – 1 February 1914), was a German-born British zoologist, ichthyologist, and herpetologist. Günther is ranked the second-most productive reptile taxonomist (after George Albert Boulenger) with more than 340 reptile species described. Early life and career Günther was born in Esslingen in Swabia (Württemberg). His father was a ''Stiftungs-Commissar'' in Esslingen and his mother was Eleonora Nagel. He initially schooled at the Stuttgart Gymnasium. His family wished him to train for the ministry of the Lutheran Church for which he moved to the University of Tübingen. A brother shifted from theology to medicine, and he, too, turned to science and medicine at Tübingen in 1852. His first work was "''Ueber den Puppenzustand eines Distoma''". He graduated in medicine with an M.D. from Tübingen in 1858, the same year in which he published a handbook of zoology for students of ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Day Gecko
''Phelsuma'' is a large genus of geckos in the family Gekkonidae. Species in the genus ''Phelsuma'' are commonly referred to as day geckos. Some day geckos are seriously endangered and some are common, but all ''Phelsuma'' species are CITES Appendix II listed. Little is known about trade in day geckos, but the IUCN considers it a threat to some species. Some species are captive-bred. Taxonomy The genus itself is thought to have originated anywhere between the Late Cretaceous to the mid-Eocene (43 to 75 mya), as that is when its lineage is known to have diverged from the one containing the Namaqua day gecko (''Rhoptropella''), although it is unknown how closely related both genera are. The crown group containing all recent species is thought to have originated in the early Oligocene, about 30 million years ago, with the most basal of them being the isolated Andaman day gecko (''P. andamanensis''), which diverged from all other species shortly after the crown group originated ...

Rodrigues (island)
Rodrigues (french: Île Rodrigues, link=yes ; Creole: ) is a autonomous outer island of the Republic of Mauritius in the Indian Ocean, about east of Mauritius. It is part of the Mascarene Islands, which include Mauritius and Réunion. Rodrigues is of volcanic origin and is surrounded by coral reef, and some tiny uninhabited islands lie just off its coast. The island used to be the tenth District of Mauritius; it gained autonomous status on 10 December 2002, and it is governed by the Rodrigues Regional Assembly. The capital of the island is Port Mathurin. The islands of Rodrigues, Agaléga and Saint Brandon form part of the larger territory of the Republic of Mauritius. Its inhabitants are Mauritian citizens. , the island's population was about 41,669, according to Statistics Mauritius. Most of the inhabitants are of African descent. Its economy is based mainly on fishing, farming, handicraft and a developing tourism sector. Etymology and history The uninhabited island w ...

Latania
''Latania'', commonly known as latan palm or latania palm, is a genus of flowering plant in the palm tree family, native to the Mascarene Islands in the western Indian Ocean. Species The genus contains three species, one from each of the three major islands (including islets) in the chain. All species have been ranked as Endangered by the IUCN. Latan palms are large, single-stemmed fan palms with separate male and female plants (dioecy); when the leaves fall, they leave scars on the trunks. Male flowers are small, in clusters, and emerge from within leathery bracts on the catkin-like inflorescence An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Morphologically, it is the modified part of the shoot of seed plants where flowers are formed o ...s. Female flowers are larger, solitary and not concealed within bracts. The fruits contain 1-3 pyrenes, which are seeds enclosed with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black Rat
The black rat (''Rattus rattus''), also known as the roof rat, ship rat, or house rat, is a common long-tailed rodent of the stereotypical rat genus ''Rattus'', in the subfamily Murinae. It likely originated in the Indian subcontinent, but is now found worldwide. The black rat is black to light brown in colour with a lighter underside. It is a generalist omnivore and a serious pest to farmers because it feeds on a wide range of agricultural crops. It is sometimes kept as a pet. In parts of India, it is considered sacred and respected in the Karni Mata Temple in Deshnoke. Taxonomy ''Mus rattus'' was the scientific name proposed by Carl Linnaeus in 1758 for the black rat. Three subspecies were once recognized, but today are considered invalid and are now known to be actually color morphs: *''Rattus rattus rattus'' – roof rat *''Rattus rattus alexandrinus'' – Alexandrine rat *''Rattus rattus frugivorus'' – fruit rat Characteristics A typical adult black rat is long, n ...

The IUCN Red List Of Threatened Species
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 provide sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
