Sitana Ponticeriana
The Pondichéry fan-throated lizard (''Sitana ponticeriana'') is a species of agamid lizard found in eastern peninsular India. It was earlier thought to be widespread but studies in 2016 resulted in the splitting of the group into several species placed in two genera. The genus ''Sitana'' has an enlarged projecting scale on the posterior side of the hind thigh which is absent in the sister genus ''Sarada''. The species is found mostly on the ground in open ground patches in thin forests. When disturbed this lizard sometimes runs with a bipedal gait. Descriptions Upper head-scales small, sharply keeled; ''canthus rostralis'' and supraciliary edge sharp, with much enlarged scales. Dorsal scales larger than ventrals, with sharp keels forming straight longitudinal lines; lateral scales smallest, uniform or intermixed with scattered enlarged ones. The fore limb does not extend on to the vent, if laid backwards; the hind limb reaches to the orbit, if laid forwards; the lower thigh ...

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] |
Coromandel Coast
The Coromandel Coast is the southeastern coastal region of the Indian subcontinent, bounded by the Utkal Plains to the north, the Bay of Bengal to the east, the Kaveri delta to the south, and the Eastern Ghats to the west, extending over an area of about 22,800 square kilometres. The coast has an average elevation of 80 metres and is backed by the Eastern Ghats, a chain of low lying and flat-topped hills. In historical Muslim sources from the 12th century onward, the Coromandel Coast was called Maʿbar. Etymology The land of the Chola dynasty was called ''Cholamandalam'' (சோழ மண்டலம்) in Tamil, translated as ''The realm of the Cholas'', from which the Portuguese derived the name ''Coromandel''.''The Land of the Tamulians and Its Missions'', by Eduard Raimund Baierlein, James Dunning BakerSouth Indian Coins – Page 61 by T.

Reptiles Of Sri Lanka
This is a list of reptiles of Sri Lanka. The reptilian diversity in Sri Lanka is higher than the diversity of other vertebrates such as mammals and fish with 181 reptile species. All extant reptiles are well documented through research by many local and foreign scientists and naturalists. Sri Lankan herpetologist, Anslem de Silva largely studied the biology and ecology of Sri Lanka snakes, where he documented 96 species of land and sea snakes. Five genera are endemic to Sri Lanka - ''Aspidura'', ''Balanophis'', ''Cercaspis'', ''Haplocercus'', and ''Pseudotyphlops''. Out of them only five of the land snakes are considered potentially deadly and life threatening to humans. Among snakes, 54 are endemic to Sri Lanka. The total increased to 107 with new descriptions of ''Dendrelaphis'', ''Rhinophis'', ''Aspidura'' and ''Dryocalamus''. Lizard diversity in the island has been documented and studied by many local scientists and researchers such as Imesh Nuwan Bandara, Kalana Maduwage, Anj ...

Reptiles Of India
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 originate ...

Sitana
''Sitana'' is a genus of lizards, collectively known as the fan-throated lizards, from the family Agamidae. They are found in Nepal, India, Sri Lanka and Pakistan. The genus comprises fourteen species, including several recently discovered species, such as two new species from Sri Lanka. In 2016, a new genus named ''Sarada (lizard), Sarada'' was erected, consisting of one former ''Sitana'' species and two newly described ones. ''Sarada'' is the sister genus of ''Sitana''. Together they form a clade which sister group is ''Otocryptis''. Description ''Sitana'' are small to medium-sized lizards. They are ground dwellers, primarily eating insects but also mollusks and plant seeds. Males measure and females in snout–vent length. In an example of convergent evolution, males have prominent dewlaps, similar to anoles, which are used in communication during the breeding season. The dewlap may be small to large, depending on the species. Females lack the dewlap. Species There are four ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Georges Cuvier
Jean Léopold Nicolas Frédéric, Baron Cuvier (; 23 August 1769 – 13 May 1832), known as Georges Cuvier, was a French natural history, naturalist and zoology, zoologist, sometimes referred to as the "founding father of paleontology". Cuvier was a major figure in natural sciences research in the early 19th century and was instrumental in establishing the fields of comparative anatomy and paleontology through his work in comparing living animals with fossils. Cuvier's work is considered the foundation of vertebrate paleontology, and he expanded Linnaean taxonomy by grouping classes into phylum, phyla and incorporating both fossils and living species into the classification. Cuvier is also known for establishing extinction as a fact—at the time, extinction was considered by many of Cuvier's contemporaries to be merely controversial speculation. In his ''Essay on the Theory of the Earth'' (1813) Cuvier proposed that now-extinct species had been wiped out by periodic catastrophi ...

Forest
A forest is an area of land dominated by trees. Hundreds of definitions of forest are used throughout the world, incorporating factors such as tree density, tree height, land use, legal standing, and ecological function. The United Nations' Food and Agriculture Organization (FAO) defines a forest as, "Land spanning more than 0.5 hectares with trees higher than 5 meters and a canopy cover of more than 10 percent, or trees able to reach these thresholds ''in situ''. It does not include land that is predominantly under agricultural or urban use." Using this definition, '' Global Forest Resources Assessment 2020'' (FRA 2020) found that forests covered , or approximately 31 percent of the world's land area in 2020. Forests are the predominant terrestrial ecosystem of Earth, and are found around the globe. More than half of the world's forests are found in only five countries (Brazil, Canada, China, Russia, and the United States). The largest share of forests (45 percent) are in th ...
