Dermophis Glandulosus
''Dermophis glandulosus'' is a species of caecilian in the family Dermophiidae. It is found in northwestern Colombia ( Córdoba and Antioquia Departments), Costa Rica, and Panama. It is the southernmost species among ''Dermophis''. Description ''Dermophis glandulosus'' is a moderately large caecilian, measuring up to in total length. The type specimen was a juvenile measuring 159 mm. Also subsequent specimens were relatively small, leading to a conclusion that it was synonymous with '' Dermophis parviceps''. However, new specimens have shown ''Dermophis glandulosus'' to be a separate, much larger species than ''Dermophis parviceps''. It also lacks the contrasting head coloration of the latter and has more secondary annuli. The dorsum is purplish lavender, whereas the ventral surfaces are dull cream with dim lavender clouding. Habitat and conservation ''Dermophis glandulosus'' occurs in humid montane and lowland forests. In Colombia it occurs at elevations of above se ...

Edward Harrison Taylor
Edward Harrison Taylor (April 23, 1889 – June 16, 1978) was an American herpetologist from Missouri. Family Taylor was born in Maysville, Missouri, to George and Loretta Taylor. He had an older brother, Eugene. Education Taylor studied at the University of Kansas in Lawrence, Kansas, graduating with a B.A. in 1912. Field trips during his time at the University of Kansas with Dr. Clarence McClung and Dr. Roy Moody helped prepare Taylor for his future endeavors. Between 1916 and 1920 he returned briefly to Kansas to finish his M.A. Career Upon completing his bachelor's degree, Taylor went to the Philippines, where at first he held a teacher's post in a village in central Mindanao. He collected and studied the local herpetofauna extensively and published many papers. He returned to the Philippines after completing his master's degree and was appointed Chief of Fisheries in Manila. On his many survey trips he continued collecting and studying fishes and reptiles of the islan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Above Sea Level
Height above mean sea level is a measure of the vertical distance (height, elevation or altitude) of a location in reference to a historic mean sea level taken as a vertical datum. In geodesy, it is formalized as ''orthometric heights''. The combination of unit of measurement and the physical quantity (height) is called "metres above mean sea level" in the metric system, while in United States customary and imperial units it would be called "feet above mean sea level". Mean sea levels are affected by climate change and other factors and change over time. For this and other reasons, recorded measurements of elevation above sea level at a reference time in history might differ from the actual elevation of a given location over sea level at a given moment. Uses Metres above sea level is the standard measurement of the elevation or altitude of: * Geographic locations such as towns, mountains and other landmarks. * The top of buildings and other structures. * Flying objects such ...

Taxa Named By Edward Harrison Taylor
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in '' Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Amphibians Of Costa Rica
Amphibians are tetrapod, four-limbed and ectothermic vertebrates of the Class (biology), class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial animal, terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. The young generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles like lizards but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed. With their complex reproductive needs and permeable skins, amphibians are often ecological indicators; in re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Deforestation
Deforestation or forest clearance is the removal of a forest or stand of trees from land that is then converted to non-forest use. Deforestation can involve conversion of forest land to farms, ranches, or urban use. The most concentrated deforestation occurs in tropical rainforests. About 31% of Earth's land surface is covered by forests at present. This is one-third less than the forest cover before the expansion of agriculture, a half of that loss occurring in the last century. Between 15 million to 18 million hectares of forest, an area the size of Bangladesh, are destroyed every year. On average 2,400 trees are cut down each minute. The Food and Agriculture Organization of the United Nations defines deforestation as the conversion of forest to other land uses (regardless of whether it is human-induced). "Deforestation" and "forest area net change" are not the same: the latter is the sum of all forest losses (deforestation) and all forest gains (forest expansion) in a gi ...

Viviparous
Among animals, viviparity is development of the embryo inside the body of the parent. This is opposed to oviparity which is a reproductive mode in which females lay developing eggs that complete their development and hatch externally from the mother. The term 'viviparity' and its adjective form 'viviparous' derive from the Latin ''vivus'' meaning "living" and ''pario'' meaning "give birth to". Reproductive mode Five modes of reproduction have been differentiated in animals based on relations between zygote and parents. The five include two nonviviparous modes: ovuliparity, with external fertilisation, and oviparity, with internal fertilisation. In the latter, the female lays zygotes as eggs with a large yolk; this occurs in all birds, most reptiles, and some fishes. These modes are distinguished from viviparity, which covers all the modes that result in live birth: *Histotrophic viviparity: the zygotes develop in the female's oviducts, but find their nutrients by oophagy ...
