Centrolene Prosoblepon
''Centrolene prosoblepon'' is a species of frog in the family Centrolenidae, commonly known as the emerald glass frog or Nicaragua giant glass frog. This species can be found in Ecuador, Colombia, Panama, Costa Rica, Nicaragua, and Honduras. Its natural habitats are lowland tropical forests and montane cloud forests. It is a nocturnal species occurring in low vegetation in mature forests only. It is not considered threatened overall by the IUCN although deforestation and pollution are potential threats, as is chytridiomycosis. The word "prosoblepon" originates from the Greek words "proso" and "blepo", which respectively mean "forward, in front" and "see, look”, and is thought to signify the frontal position of the eyes in the emerald glass frog. General Description ''Centrolene prosoblepon'' is listed as least concern according to IUCN in the red list category and criteria when it was assessed in 2008. It was listed as least concern because of its wide distrib ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oskar Boettger
Oskar Boettger (german: Böttger; 31 March 1844 – 25 September 1910) was a German zoologist who was a native of Frankfurt am Main. He was an uncle of the noted malacologist Caesar Rudolf Boettger (1888–1976). From 1863 to 1866 he studied at the Bergakademie Freiberg, then worked for a year in a chemical factory in Frankfurt am Main."Boettger, Oskar" p. 410. In: (1955). '' Neue Deutsche Biographie (NDB).

Rainforest
Rainforests are characterized by a closed and continuous tree canopy, moisture-dependent vegetation, the presence of epiphytes and lianas and the absence of wildfire. Rainforest can be classified as tropical rainforest or temperate rainforest, but other types have been described. Estimates vary from 40% to 75% of all biotic species being indigenous to the rainforests. There may be many millions of species of plants, insects and microorganisms still undiscovered in tropical rainforests. Tropical rainforests have been called the "jewels of the Earth" and the " world's largest pharmacy", because over one quarter of natural medicines have been discovered there. Rainforests as well as endemic rainforest species are rapidly disappearing due to deforestation, the resulting habitat loss and pollution of the atmosphere. Definition Rainforest are characterized by a closed and continuous tree canopy, high humidity, the presence of moisture-dependent vegetation, a moist layer of lea ...

Amphibians Described In 1892
Amphibians are four-limbed and ectothermic vertebrates of the class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within 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 recent decades there has been a dramatic decline ...

Amphibians Of Panama
This is a list of amphibians found in Panama. 205 amphibian species have been registered in Panama, which are grouped in 3 orders: Caecilians (Gymnophiona), Salamanders (Caudata) and Frogs and Toads (Anura). This list is derived from the database listing of AmphibiaWeb.AmphibiaWeb 2012 25 species are critically endangered(CR), 16 species are endangered (EN) and 6 species are vulnerable (VU). One species has recently (September 2016) gone extinct with the last individual in captivity dying, and with not a single specimen seen nor heard in the wild for over a decade. Several other species might also be extinct with no specimen found for decades. The following tags are used to highlight specific species' conservation status as assessed by the IUCN: Caecilians (Gymnophiona) Caeciliidae Order: Gymnophiona. Family: Caeciliidae *'' Caecilia isthmica'' (DD) *'' Caecilia leucocephala'' (LC) *'' Caecilia nigricans'' (LC) *'' Caecilia tentaculata'' (LC) *'' Caecilia volcani'' (DD) *'' ...

Espadarana
''Espadarana'' is a genus of glass frogs. They are found in Central America (Honduras, Nicaragua, Costa Rica, Panama) and northern South America (Venezuela, Colombia, and Ecuador). Etymology The generic name ''Espadarana'' honors Marcos Jiménez de la Espada, a Spanish zoologist. Among other things, he described the first centrolenid frog, '' Centrolene geckoideum'' in 1872. Moreover, the Spanish word ''espada'' means "sword", which can be associated with the humeral spines that adult male ''Espadarana'' have. Description The diagnostic characters of ''Espadarana'' include conspicuous humeral spines present in adult males, as hinted in their name. There is moderate webbing between third and fourth fingers. The dorsum is lavender in preserved individuals and may have spots. Internal features include green bones (in live specimens), lobed liver covered by a transparent hepatic peritoneum, whereas the ventral parietal peritoneum is white in its anterior part and transparent in it ...

Monteverde
Monteverde is the twelfth canton of the Puntarenas province of Costa Rica. It is located in the Cordillera de Tilarán mountain range. Roughly a four-hour drive from the Central Valley, Monteverde is one of the country's major ecotourism destinations. The area is host to the Monteverde Cloud Forest Reserve and several other natural attractions, which draw considerable numbers of tourists and naturalists. National Geographic has called the Monteverde Cloud Forest Biological Reserve "the jewel in the crown of cloud forest reserves". Newsweek has declared Monteverde the world's #14 "Place to Remember Before it Disappears". By popular vote in Costa Rica, Monteverde was deemed one of the ''Seven Natural Wonders of Costa Rica'', along with Isla del Coco, Volcán Arenal, Cerro Chirripó, Río Celeste, Tortuguero, and Volcán Poás. Santa Elena is the head town. Its homes and businesses serve as the region's tourist hub, along with the nearby neighborhood of Cerro Plano, the ...

Batrachochytrium Dendrobatidis
''Batrachochytrium dendrobatidis'' ( ), also known as ''Bd'' or the amphibian chytrid fungus, is a fungus that causes the disease chytridiomycosis in amphibians. Since its discovery in 1998 by Lee Berger, the disease devastated amphibian populations around the world, in a global decline towards multiple extinctions, part of the Holocene extinction. A recently described second species, '' B. salamandrivorans'', also cause chytridiomycosis and death in salamanders. The fungal pathogens that cause the disease chytridiomycosis ravage the skin of frogs, toads, and other amphibians, throwing off their balance of water and salt and eventually causing heart failure, Nature reports. Some amphibian species appear to have an innate capacity to withstand chytridiomycosis infection due to symbiosis with ''Janthinobacterium lividum''. Even within species that generally succumb, some populations survive, possibly demonstrating that these traits or alleles of species are being subjected to evo ...
