Dromicus
''Alsophis'' is a genus of snakes in the subfamily Dipsadinae of the family Colubridae. Species in the genus ''Alsophis'' are among those snakes commonly called "racers". ''Alsophis'' species are endemic to the Lesser Antilles in the Caribbean. One species in the genus ''Alsophis'', ''A. antiguae'', is one of the world's rarest known snakes. Snakes of the genus ''Alsophis'' are small and rear-fanged, and they are considered harmless to humans. This genus contains nine described species which are recognized as being valid. Several species once included in this genus have been placed in the genera ''Borikenophis'' and '' Pseudalsophis''. Rarest species '' Alsophis antiguae'' is the rarest snake in the genus ''Alsophis''. This snake once occurred on Antigua and Barbuda, but by 1995, only 50 individuals remained on Great Bird Island, off the coast of Antigua. Following the removal of invasive alien predators and successful reintroductions to a further three islands (Rabbit in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |

Leeward Island Racer
The Leeward Island racer (''Alsophis rijgersmaei'') is a species of snake in the family Colubridae. The species is found in Anguilla, Saint Barthélemy, and is probably extirpated from Sint Maarten. Taxonomy It was named by Edward Drinker Cope in 1869, the specific name honouring the Dutch government physician in St. Maarten, Hendrik Elingsz van Rijgersma, who was an avid amateur naturalist.Beolens, Bo; Watkins, Michael; Grayson, Michael (2011). ''The Eponym Dictionary of Reptiles''. Baltimore: Johns Hopkins University Press. xiii + 296 pp. . ("''Alsophis rijgersmai'' ic, p. 222). Conservation It was thought to have been eradicated by the mongoose (Westerman, 1955; Sajdak and Henderson, 1991 in Powell et al., 1992). However, in 1992 there was a report of five specimens that were captured at Mary's Fancy, and in the same year one was observed in the field (Powell et al., 1992). A snake was also seen after the hurricane in January 1996 during a field trip at Flagstaf (Ecovisio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edward Drinker Cope
Edward Drinker Cope (July 28, 1840 – April 12, 1897) was an American zoologist, paleontologist, comparative anatomist, herpetologist, and ichthyologist. Born to a wealthy Quaker family, Cope distinguished himself as a child prodigy interested in science; he published his first scientific paper at the age of 19. Though his father tried to raise Cope as a gentleman farmer, he eventually acquiesced to his son's scientific aspirations. Cope married his cousin and had one child; the family moved from Philadelphia to Haddonfield, New Jersey, although Cope would maintain a residence and museum in Philadelphia in his later years. Cope had little formal scientific training, and he eschewed a teaching position for field work. He made regular trips to the American West, prospecting in the 1870s and 1880s, often as a member of United States Geological Survey teams. A personal feud between Cope and paleontologist Othniel Charles Marsh led to a period of intense fossil-finding competition ...

Hermann Schlegel
Hermann Schlegel (10 June 1804 – 17 January 1884) was a German ornithologist, herpetologist and ichthyologist. Early life and education Schlegel was born at Altenburg, the son of a brassfounder. His father collected butterflies, which stimulated Schlegel's interest in natural history. The discovery, by chance, of a buzzard's nest led him to the study of birds, and a meeting with Christian Ludwig Brehm. Schlegel started to work for his father, but soon tired of it. He travelled to Vienna in 1824, where, at the university, he attended the lectures of Leopold Fitzinger and Johann Jacob Heckel. A letter of introduction from Brehm to gained him a position at the Naturhistorisches Museum. Ornithological career One year after his arrival, the director of this natural history museum, Carl Franz Anton Ritter von Schreibers, recommended him to Coenraad Jacob Temminck, director of the natural history museum of Leiden, who was seeking an assistant. At first Schlegel worked mainly o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
