Andinobates Abditus
''Andinobates abditus'' is a species of poison dart frog, sometimes known as the Collins' poison frog. It is endemic to Ecuador where it is only known from its type locality, at the eastern base of the Reventador volcano, in the Napo Province. ''Andinobates abditus'' no longer survives in its type locality, although it is possible that it occurs elsewhere (including the nearby Cayambe Coca Ecological Reserve Cayambe Coca National Park is a national park in Ecuador located along the Equator about from Quito. The park encompasses an area of . The reserve The park includes two very different regions of Ecuador, the high altitude sierra with Cayambe ..., but its presence there has not been confirmed). The disappearance from the type locality was due to habitat loss, possibly together '' Batrachochytrium dendrobatidis'' infection. The type locality was characterized by dense, humid forest with many mosses and epiphytes. References Amphibians described in 1976 Andinobat ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Poison Dart Frog
Poison dart frog (also known as dart-poison frog, poison frog or formerly known as poison arrow frog) is the common name of a group of frogs in the family Dendrobatidae which are native to tropical Central and South America. These species are diurnal and often have brightly colored bodies. This bright coloration is correlated with the toxicity of the species, making them aposematic. Some species of the family Dendrobatidae exhibit extremely bright coloration along with high toxicity, while others have cryptic coloration with minimal to no amount of observed toxicity. The species that have great toxicity derive this feature from their diet of ants, mites and termites. However, other species that exhibit cryptic coloration, and low to no amounts of toxicity, eat a much larger variety of prey. Many species of this family are threatened due to human infrastructure encroaching on their habitats. These amphibians are often called "dart frogs" due to the Native Americans' use of the ...

Ecuador
Ecuador ( ; ; Quechua: ''Ikwayur''; Shuar: ''Ecuador'' or ''Ekuatur''), officially the Republic of Ecuador ( es, República del Ecuador, which literally translates as "Republic of the Equator"; Quechua: ''Ikwadur Ripuwlika''; Shuar: ''Ekuatur Nunka''), is a country in northwestern South America, bordered by Colombia on the north, Peru on the east and south, and the Pacific Ocean on the west. Ecuador also includes the Galápagos Islands in the Pacific, about west of the mainland. The country's capital and largest city is Quito. The territories of modern-day Ecuador were once home to a variety of Indigenous groups that were gradually incorporated into the Inca Empire during the 15th century. The territory was colonized by Spain during the 16th century, achieving independence in 1820 as part of Gran Colombia, from which it emerged as its own sovereign state in 1830. The legacy of both empires is reflected in Ecuador's ethnically diverse population, with most of its mill ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type Locality (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almost a ...

Reventador
Reventador is an active stratovolcano which lies in the eastern Andes of Ecuador. It lies in a remote area of the national park of the same name, which is Spanish for "exploder". Since 1541, it has erupted over 25 times, although its isolated location means that many of its eruptions have gone unreported. The largest historical eruption occurred in 2002. During that eruption, the plume from the volcano reached a height of and pyroclastic flows proceeded to from the cone. On March 30, 2007, the mountain ejected ash to a height of about . No injuries or damage were reported. Its most recent eruption began on 27 July 2008, and it has remained in continuing eruption status (intermittent eruptive events without a break of 3 months or more) as of 15 October 2021. Reventador is part of a chain of volcanoes in the Cordillera Real, much further east than the main volcanic axis of the region. The volcano rises above the jungles of the western Amazon basin and the flanks are densely clad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Napo Province
Napo () is a province in Ecuador. Its capital is Tena. The province contains the Napo River. The province is low developed without much industrial presence. The thick rainforest is home to many natives that remain isolated by preference, descendants of those who fled the Spanish invasion in the Andes, and the Incas years before. In 2000, the province was the sole remaining majority-indigenous province of Ecuador, with 56.3% of the province either claiming indigenous identity or speaking an indigenous language. This province is one of the many located in Ecuador's section of the Amazon Rainforest. In Napo province are also Antisana Ecological Reserve, Sumaco Napo-Galeras National Park, and Limoncocha National Biological Reserve. Cantons The province is divided into five cantons. The following table lists each with its population at the 2001 census, its area in square kilometres (km²), and the name of the canton seat or capital.

Cayambe Coca Ecological Reserve
Cayambe Coca National Park is a national park in Ecuador located along the Equator about from Quito. The park encompasses an area of . The reserve The park includes two very different regions of Ecuador, the high altitude sierra with Cayambe volcano and the hot, humid rainforest of the Amazon basin as well as the intervening temperate cloud forest. There are three entrances, and the one chosen by the visitor will reflect which region they wish to visit because there are few tracks within the park. The entrance near the town of Cayambe in Pichincha Province provides access to the mountain. The high level "Ruales-Oleas-Bergé Refuge" is a mountain hut with accommodation for those who wish to climb the volcano, while other attractions include lakes, waterfalls and forests. An entrance near Papallacta in Napo Province provides access to the forests and lakelets in the Andean foothills and the Páramo, an area of tropical, montane vegetation above the treeline. A third entrance ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Amphibians Described In 1976
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 ...

Andinobates
''Andinobates'' is a genus of poison dart frogs from Ecuador, Colombia and Panama. It contains species formerly classified in the genus ''Dendrobates'' and in 2006 transferred to the genus ''Ranitomeya''. In 2011 Twomey, Brown, and their colleagues erected the genus ''Andinobates'' for a group of 12 species of ''Ranitomeya''. ''Andinobates'' frogs can be distinguished from their sister taxon ''Ranitomeya'' anatomically in that their 2nd and 3rd vertebrae are fused. They show no limb reticulation, which is present in most species of ''Ranitomeya''. Distribution ''Andinobates'' inhabits the rainforests of Ecuador, Colombia, and Panama Panama ( , ; es, link=no, Panamá ), officially the Republic of Panama ( es, República de Panamá), is a transcontinental country spanning the southern part of North America and the northern part of South America. It is bordered by Cos ..., whereas ''Ranitomeya'' is only found in the Amazonian basin. Species ''Andinobates'' primaril ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
