Lepidodactylus Listeri
''Lepidodactylus listeri'', also known commonly as Lister's gecko or the Christmas Island chained gecko, is a species of gecko, a lizard in the family Gekkonidae, endemic to Christmas Island in the Indian Ocean. It is currently extinct in the wild. Geographic range ''L. listeri'' is endemic to Christmas Island. Etymology Both the specific name, ''listeri'', and one of the common names, Lister's gecko, are in honour of British naturalist Joseph Jackson Lister.xiii + 296 pp. Description Lister's gecko is a brown lizard growing to a snout-vent length (SVL) of . It has a broad, pale fawn/grey vertebral stripe which expands to cover the top of the head and matches the colour and pattern of the tail. It has a whitish belly. The body is covered with small, smooth scales. ''L. listeri'' was most abundant in primary rainforest on the plateau, but also occurs in disturbed secondary forest growth. It was absent from mined areas on the island.Cogger HG, Sadlier RA (1999). ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George Albert Boulenger
George Albert Boulenger (19 October 1858 – 23 November 1937) was a Belgian-British zoologist who described and gave scientific names to over 2,000 new animal species, chiefly fish, reptiles, and amphibians. Boulenger was also an active botanist during the last 30 years of his life, especially in the study of roses. Life Boulenger was born in Brussels, Belgium, the only son of Gustave Boulenger, a Belgian public notary, and Juliette Piérart, from Valenciennes. He graduated in 1876 from the Free University of Brussels with a degree in natural sciences, and worked for a while at the Royal Belgian Institute of Natural Sciences, Brussels, as an assistant naturalist studying amphibians, reptiles, and fishes. He also made frequent visits during this time to the ''Muséum national d'Histoire naturelle'' in Paris and the British Museum in London. In 1880, he was invited to work at the Natural History Museum, then a department of the British Museum, by Dr. Albert C. L. G. Günt ...

Reptiles Described In 1889
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 ...

Fauna Of Christmas Island
The wildlife of Christmas Island is composed of the flora and fauna of this isolated island in the tropical Indian Ocean. Christmas Island is the summit plateau of an underwater volcano. It is mostly clad in tropical rainforest and has karst, cliffs, wetlands, coasts and sea. It is a small island with a land area of , 63% of which has been declared a National park. Most of the rainforest remains intact and supports a large range of endemic species of animals and plants. Geography The island is about long and wide. The total land area is , with of coastline. The island is the flat summit of an underwater volcano more than high, with about being submerged and only about above the surface. Some basalt is exposed in places but most of the surface rock is limestone accumulated from coral growth. The karst terrain supports numerous anchialine pools. Steep cliffs along much of the coast rise abruptly to a central plateau. The island is mainly covered by tropical rainforest, much ...

Geckos Of Australia
Geckos are small, mostly carnivorous lizards that have a wide distribution, found on every continent except Antarctica. Belonging to the infraorder Gekkota, geckos are found in warm climates throughout the world. They range from . Geckos are unique among lizards for their vocalisations, which differ from species to species. Most geckos in the family Gekkonidae use chirping or clicking sounds in their social interactions. Tokay geckos (''Gekko gecko'') are known for their loud mating calls, and some other species are capable of making hissing noises when alarmed or threatened. They are the most species-rich group of lizards, with about 1,500 different species worldwide. All geckos, except species in the family Eublepharidae lack eyelids; instead, the outer surface of the eyeball has a transparent membrane, the cornea. They have a fixed lens within each iris that enlarges in darkness to let in more light. Since they cannot blink, species without eyelids generally lick t ...

List Of Reptiles Of Christmas Island
This is a list of the reptile species recorded on Christmas Island. At the time of human settlement in the late 19th century, the island had five native species of lizard and one native snake. However, additional species were introduced during the 20th century, resulting in dramatic declines in the island's native reptile populations. Lizards Christmas Island had five native lizard species at the time of human settlement, although the Christmas Island forest skink (''Emoia nativitatis'') is now considered Extinction, extinct, and the Cryptoblepharus egeriae, blue-tailed skink (''Cryptoblepharus egeriae'') and Lepidodactylus listeri, Lister's gecko (''Lepidodactylus listeri'') are extinct in the wild. Three additional species were introduced during the 20th century. Snakes Christmas Island has one endemic snake species, the Christmas Island blind snake (''Ramphotyphlops exocoeti''). The Indotyphlops braminus, flowerpot blind snake (''Ramphotyphlops braminus'') had been intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cryptoblepharus Egeriae
''Cryptoblepharus egeriae'', also known commonly as the blue-tailed shinning-skink, the Christmas Island blue-tailed shinning-skink, and the Christmas Island blue-tailed skink, is a species of lizard in the family Scincidae that was once endemic to Christmas Island. The Christmas Island blue-tailed skink was discovered in 1888. (''Ablepharus egeriae'', new species, pp. 535–536). It was formerly the most abundant reptile on the island, and occurred in high numbers particularly near the human settlement. However, the Christmas Island blue-tailed skink began to decline sharply outwardly from the human settlement by the early 1990s, which coincided with the introduction of a predatory snake and the introduction of the yellow crazy ant (''Anoplolepis gracilipes'') in the mid-1980s. By 2006, the Christmas Island blue-tailed skink was on the endangered animals list, and by 2010 the Christmas Island blue-tailed skink was extinct in the wild. From 2009-2010, parks Australia and Tarong ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lycodon Capucinus
''Lycodon capucinus'', also known as the Oriental wolf snake, is a species of colubrid snake, which is commonly found in the Indo-Australian Archipelago. Named after their enlarged front teeth, which gives them a muzzled appearance similar to canines, it also makes the snout somewhat more squarish than other snakes. Description A slender-bodied small snake that ranges from barely three feet to less than one meter. Most wild-caught specimens usually reach less than these lengths. Coloration is adapted for life underground and on the forest floor. Shades of jet black, reddish-brown or dark gray with speckles, blotches and spots of white or pale yellow scattered over the body are its usual colors. There is also a distinct white coloration around its neck. Their color patterns vary from one geographic location to another. There are albino-colored ones which are very rare among this snake species. The snout is duck-bill-shaped for digging in soft or sandy ground. They have enlarged fr ...

Diploidy
Ploidy () is the number of complete sets of chromosomes in a cell, and hence the number of possible alleles for autosomal and pseudoautosomal genes. Sets of chromosomes refer to the number of maternal and paternal chromosome copies, respectively, in each homologous chromosome pair, which chromosomes naturally exist as. Somatic cells, tissues, and individual organisms can be described according to the number of sets of chromosomes present (the "ploidy level"): monoploid (1 set), diploid (2 sets), triploid (3 sets), tetraploid (4 sets), pentaploid (5 sets), hexaploid (6 sets), heptaploid or septaploid (7 sets), etc. The generic term polyploid is often used to describe cells with three or more chromosome sets. Virtually all sexually reproducing organisms are made up of somatic cells that are diploid or greater, but ploidy level may vary widely between different organisms, between different tissues within the same organism, and at different stages in an organism's life cycle.

Parthenogenesis
Parthenogenesis (; from the Greek grc, παρθένος, translit=parthénos, lit=virgin, label=none + grc, γένεσις, translit=génesis, lit=creation, label=none) is a natural form of asexual reproduction in which growth and development of embryos occur in a gamete (egg or sperm) without combining with another gamete (e.g., egg and sperm fusing). In animals, parthenogenesis means development of an embryo from an unfertilized egg cell. In plants, parthenogenesis is a component process of apomixis. In algae, parthenogenesis can mean the development of an embryo from either an individual sperm or an individual egg. Parthenogenesis occurs naturally in some plants, algae, invertebrate animal species (including nematodes, some tardigrades, water fleas, some scorpions, aphids, some mites, some bees, some Phasmatodea and parasitic wasps) and a few vertebrates (such as some fish, amphibians, reptiles and birds). This type of reproduction has been induced artificially i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polyploidy
Polyploidy is a condition in which the biological cell, cells of an organism have more than one pair of (Homologous chromosome, homologous) chromosomes. Most species whose cells have Cell nucleus, nuclei (eukaryotes) are diploid, meaning they have two sets of chromosomes, where each set contains one or more chromosomes and comes from each of two parents, resulting in pairs of homologous chromosomes between sets. However, some organisms are polyploid. Polyploidy is especially common in plants. Most eukaryotes have diploid somatic cells, but produce haploid gametes (eggs and sperm) by meiosis. A Ploidy, monoploid has only one set of chromosomes, and the term is usually only applied to cells or organisms that are normally diploid. Males of bees and other Hymenoptera, for example, are monoploid. Unlike animals, plants and multicellular algae have Biological life cycle, life cycles with two alternation of generations, alternating multicellular generations. The gametophyte generation is ...
