Dermophis Costaricense
''Dermophis costaricense'' is a species of caecilian in the family Dermophiidae. It is endemic to Costa Rica and is found on the Atlantic versant of Cordillera de Tilarán, Cordillera Central, and Cordillera de Talamanca. Its taxonomic status is in need of a review. Description ''Dermophis costaricense'' is a moderate-sized species: total length is . It is characterized by high numbers of both primary (107–117) and secondary annuli (74–96). The annuli are not darkly demarcated ventrally, as seen in ''Dermophis mexicanus'', which is also a larger species. ''D. costaricense'' appears to be closely related with '' Dermophis gracilior'' from the Pacific versant of Costa Rica, and it is possible that these two species turn out to be the same species. However, as presently known, their ranges do not overlap and they can be distinguished based on the total number of annuli (higher in ''D. costaricense''). Habitat and conservation ''Dermophis costaricense'' occurs in premontane ra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Endemic Fauna Of Costa Rica
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...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] |

Tapantí National Park
Tapantí - Cerro de la Muerte Massif National Park, ( es, Parque Nacional Tapantí - Macizo Cerro de la Muerte), is a National Park in the Central Conservation Area of Costa Rica located on the edge of the Talamanca Range, near Cartago. It protects forests to the north of Chirripó National Park, and also contains part of the Orosí River. The area known as Cerro de la Muerte Massif was added to the park on January 14, 2000. The southwest border of the protected area corresponds partially to the Route 2, (South Inter-American Highway), the Los Quetzales National Park and Los Santos Forest Reserve are located the other side of this road. Flora and fauna The park covers and two life zones: lower montane rain forest and pre-montane rain forest. These forests provide habitat for some 45 mammal species, including the Baird's tapir, kinkajou, white-faced capuchin monkey, paca, agouti, ocelot, and jaguarundi. The park's 400 bird species include sparrow hawks, resplendent quetzals, e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Braulio Carrillo National Park
Braulio Carrillo National Park is a national park in Heredia Province and San José Province, in central Costa Rica. It is part of the Central Conservation Area. Geography The park is located on the volcanic Cordillera Central (Central mountain range) between San José city and Puerto Limón on the Caribbean. It is accessible from the Limon Highway, which bisects the park (northwest to southeast), and from Barva canton on the north. The park is separated into three main sectors — Zurquí, Quebrada Gonzales, and Barva. History Established in 1978, the park was formed as an agreement with environmental lobbyists to limit and prevent development of the area after the construction of the Limon Highway, a major road linking the capital to Caribbean cargo port of Puerto Limón. The park was named in honor of former Costa Rican president Braulio Carrillo, whose administration had helped foster the nation's early agricultural economy and had built the first road linking San Jos ...

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 ...

Dermophis Gracilior
''Dermophis gracilior'' is a species of caecilian in the family Dermophiidae. It is found on the Pacific slopes of Cordillera de Talamanca in eastern Costa Rica and western Panama, as well as in the central Pacific Costa Rica. Some sources also report it from the Atlantic slope of Costa Rica. Description ''Dermophis gracilior'' is a moderate-sized caecilian measuring in total length. It has 91–117 primary and 65–96 secondary annuli. The body is somewhat robust (length 23 to 34 times the body width). The upper surface is lead-gray in color, whereas the lower one is cream with dark mottling, or largely gray to dull black. The annular grooves are similarly colored as the adjacent areas. Habitat and conservation ''Dermophis gracilior'' occurs in humid lowland, premontane, and montane forests at elevations above sea level. It is a subterranean species that can be found under logs and surface debris. It is probably viviparous. ''D. gracilior'' is a poorly known species known ...

Caecilian
Caecilians (; ) are a group of limbless, vermiform or serpentine amphibians. They mostly live hidden in the ground and in stream substrates, making them the least familiar order of amphibians. Caecilians are mostly distributed in the tropics of South and Central America, Africa, and southern Asia. Their diet consists of small subterranean creatures such as earthworms. All modern caecilians and their closest fossil relatives are grouped as a clade, Apoda , within the larger group Gymnophiona , which also includes more primitive extinct caecilian-like amphibians. The name derives from the Greek words γυμνος (''gymnos'', naked) and οφις (''ophis'', snake), as the caecilians were originally thought to be related to snakes. The body is cylindrical dark brown or bluish black in colour. The skin is slimy and bears grooves or ringlike markings. Description Caecilians completely lack limbs, making the smaller species resemble worms, while the larger species, with lengths up ...
