Coryphophylax
''Coryphophylax'' is an agamid genus endemic to the Andaman and Nicobar Islands and a sister of the Southeast Asian '' Aphaniotis''. Found in tropical wet forests, they are common in suitable habitats and shows variations across islands and are sexually dimorphic. The genus is absent on Great Nicobar Island, with its southernmost occurrence on the island of Kondul. The tsunami of December 2004 may have affected island-wide distributions in the Nicobar Islands of several species and also their gene-flow. Taxonomic history The species from the Andaman Islands was described by Edward Blyth as ''Tiaris subcristata'' in 1860 but technically published in 1861. This species was described by Fitzinger in Steindachner's publication of 1867 and as ''Tiaris humei'' by Stoliczka in 1873 and these names are considered junior synonyms but placed in the genus erected by Fitzinger. The closely related genus '' Aphaniotis'' (and the more distant ''Otocryptis'') has a concealed tympanum while ''G ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Leopold Fitzinger
Leopold Joseph Franz Johann Fitzinger (13 April 1802 – 20 September 1884) was an Austrian zoologist. Fitzinger was born in Vienna and studied botany at the University of Vienna under Nikolaus Joseph von Jacquin. He worked at the Vienna Naturhistorisches Museum between 1817, when he joined as a volunteer assistant, and 1821, when he left to become secretary to the provincial legislature of Lower Austria; after a hiatus he was appointed assistant curator in 1844 and remained at the Naturhistorisches Museum until 1861. Later he became director of the zoos of Munich and Budapest. In 1826 he published ''Neue Classification der Reptilien'', based partly on the work of his friends Friedrich Wilhelm Hemprich and Heinrich Boie. In 1843 he published ''Systema Reptilium'', covering geckos, chameleons and iguanas. Fitzinger is commemorated in the scientific names of five reptiles: '' Algyroides fitzingeri'', '' Leptotyphlops fitzingeri'', '' Liolaemus fitzingerii'', ''Micrurus tener fitzi ...

Tsunamis
A tsunami ( ; from ja, 津波, lit=harbour wave, ) is a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake. Earthquakes, volcanic eruptions and other underwater explosions (including detonations, landslides, glacier calvings, meteorite impacts and other disturbances) above or below water all have the potential to generate a tsunami. Unlike normal ocean waves, which are generated by wind, or tides, which are in turn generated by the gravitational pull of the Moon and the Sun, a tsunami is generated by the displacement of water from a large event. Tsunami waves do not resemble normal undersea currents or sea waves because their wavelength is far longer. Rather than appearing as a breaking wave, a tsunami may instead initially resemble a rapidly rising tide. For this reason, it is often referred to as a tidal wave, although this usage is not favoured by the scientific community because it might give ...

Bay Island Forest Lizard IMG 2189
A bay is a recessed, coastal body of water that directly connects to a larger main body of water, such as an ocean, a lake, or another bay. A large bay is usually called a gulf, sea, sound, or bight. A cove is a small, circular bay with a narrow entrance. A fjord is an elongated bay formed by glacial action. A bay can be the estuary of a river, such as the Chesapeake Bay, an estuary of the Susquehanna River. Bays may also be nested within each other; for example, James Bay is an arm of Hudson Bay in northeastern Canada. Some large bays, such as the Bay of Bengal and Hudson Bay, have varied marine geology. The land surrounding a bay often reduces the strength of winds and blocks waves. Bays may have as wide a variety of shoreline characteristics as other shorelines. In some cases, bays have beaches, which "are usually characterized by a steep upper foreshore with a broad, flat fronting terrace".Maurice Schwartz, ''Encyclopedia of Coastal Science'' (2006), p. 129. Bays were sig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Otocryptis
''Otocryptis'' is a genus of Agamidae, agamid lizards from the Indian subcontinent. It is the sister group for the clade formed by ''Sitana'' and ''Sarada (lizard), Sarada''.

Edward Blyth
Edward Blyth (23 December 1810 – 27 December 1873) was an English zoologist who worked for most of his life in India as a curator of zoology at the museum of the Asiatic Society of India in Calcutta. Blyth was born in London in 1810. In 1841 he travelled to India to become the curator of the museum of the Royal Asiatic Society of Bengal. He set about updating the museum's catalogues, publishing a ''Catalogue of the Birds of the Asiatic Society'' in 1849. He was prevented from doing much fieldwork himself, but received and described bird specimens from A.O. Hume, Samuel Tickell, Robert Swinhoe and others. He remained as curator until 1862, when ill-health forced his return to England. His ''Natural History of the Cranes'' was published posthumously in 1881. Avian species bearing his name include Blyth's hornbill, Blyth's leaf warbler, Blyth's hawk-eagle, Blyth's olive bulbul, Blyth's parakeet, Blyth's frogmouth, Blyth's reed warbler, Blyth's rosefinch, Blyth's shrike-babbl ...

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 ...

Sexual Dimorphism
Sexual dimorphism is the condition where the sexes of the same animal and/or plant species exhibit different morphological characteristics, particularly characteristics not directly involved in reproduction. The condition occurs in most animals and some plants. Differences may include secondary sex characteristics, size, weight, colour, markings, or behavioural or cognitive traits. These differences may be subtle or exaggerated and may be subjected to sexual selection and natural selection. The opposite of dimorphism is ''monomorphism'', which is when both biological sexes are phenotypically indistinguishable from each other. Overview Ornamentation and coloration Common and easily identified types of dimorphism consist of ornamentation and coloration, though not always apparent. A difference in coloration of sexes within a given species is called sexual dichromatism, which is commonly seen in many species of birds and reptiles. Sexual selection leads to the exaggerated dim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
