Atelopus Longirostris Male
''Atelopus'' is a large genus of Bufonidae, commonly known as harlequin frogs or toads, from Central and South America, ranging as far north as Costa Rica and as far south as Bolivia. ''Atelopus'' species are small, generally brightly colored, and diurnal. Most species are associated with mid-to-high elevation streams. This genus has been greatly affected by amphibian declines, and many species are now considered endangered, while others already are extinct. Almost 40% of the described species in the genus are considered possibly extinct; this is raised to 45% when data deficient species are added; this number may be even higher, given that the genus contains many undescribed species that could also be extinct, and many of the species considered critically endangered but extant may have gone extinct after the last surveys that detected them, or could go extinct in the future. While threatened by habitat loss, pollution, and introduced species, the primary cause of these declines ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ateleopus
''Ateleopus'' is a genus of ray-finned fish in the jellynose family Ateleopodidae. It is the type genus of its family, and the order Ateleopodiformes. For some time, it was known as ''Podateles'', because ''Ateleopus'' had been used to replace the frog genus name ''Atelopus'', which was deemed to be a spelling error. This was mistaken, however, and the fish and frog genera reverted to their original names. This genus occurs in the fossil record since the mid-Miocene. Species There are currently 4 recognized species in this genus. Several other species have been described, but these are synonyms.Kaga, T., Van Oijen, M.J.P., Kubo, Y. & Kitagawa, E. (2015): Redescription of ''Ateleopus japonicus'' Bleeker 1853, a senior synonym of ''Ateleopus schlegelii'' van der Hoeven 1855, ''Ateleopus purpureus'' Tanaka 1915, and ''Ateleopus tanabensis'' Tanaka 1918 with designation of a lectotype for ''A. japonicus'' and ''A. schlegelii'' (Ateleopodiformes: Ateleopodidae).

Introduced Species
An introduced species, alien species, exotic species, adventive species, immigrant species, foreign species, non-indigenous species, or non-native species is a species living outside its native distributional range, but which has arrived there by human activity, directly or indirectly, and either deliberately or accidentally. Non-native species can have various effects on the local ecosystem. Introduced species that become established and spread beyond the place of introduction are considered naturalized. The process of human-caused introduction is distinguished from biological colonization, in which species spread to new areas through "natural" (non-human) means such as storms and rafting. The Latin expression neobiota captures the characteristic that these species are ''new'' biota to their environment in terms of established biological network (e.g. food web) relationships. Neobiota can further be divided into neozoa (also: neozoons, sing. neozoon, i.e. animals) and neophyt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Binomial Nomenclature
In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, name or a scientific name; more informally it is also historically called a Latin name. The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Homo sapiens''. ''Tyrannosaurus rex'' is likely the most widely known binomial. The ''formal'' introduction of this system of naming species is credit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atelopus Varius
''Atelopus varius'', the Costa Rican variable harlequin toad or clown frog, is a small Neotropical true toad from the family Bufonidae (Crump 1986). Once ranging from Costa Rica to Panama, ''A. varius'' is now listed as critically endangered and has been reduced to a single remnant population near Quepos, Costa Rica (rediscovered in 2003) and has only relict populations in western Panama (IUCN). Recent variation in air temperature, precipitation, stream flow patterns, and the subsequent spread of a pathogenic chytrid fungus ''(Batrachochytrium dendrobatidis)'' linked to global climate change have been the leading cause of decline for ''A. varius'' (Lips et al. 2003 and Pounds et al. 2006). '' A. zeteki'' has been considered a subspecies of ''A. varius'', but is now generally considered a separate species (Savage, 2002). Geographic range The historic range of A. varius stretched from the Pacific and Atlantic slopes of the Cordilleras de Tilaran mountain range in Costa Rica ...

Atelopus Subornatus
''Atelopus subornatus'' is a species of toad in the family Bufonidae. It is endemic to Colombia and is restricted to the Cordillera Oriental in the Cundinamarca Department. Common name Bogota stubfoot toad has been coined for this species. Description Franz Werner described ''Atelopus subornatus'' based on three specimens (syntypes), for which the total body length was . The body is relatively slim. The head is as wide as long. The fingers have only some basal webbing whereas the toes are heavily webbed. The dorsum is dark red-brown, turning to yellowish or greenish on the sides. Breeding ''Atelopus subornatus'' breeds in streams. The egg masses are string-like, with individual embryos measuring and enclosed in a jelly capsule. Some jelly capsules are empty. The egg strings are not adherent but sink to the stream bottom and get caught by obstructions. The tadpoles are boldly marked with cream and black. Habitat and conservation ''Atelopus subornatus'' inhabits both pristin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atelopus Longirostris
''Atelopus longirostris'' is a species of Atelopus, harlequin frog, a member of the family of true toads (Bufonidae). It has been recorded only in northern Ecuador. Records from Colombia probably represent different species. As of mid-2017, it is listed as extinct by the IUCN, but was rediscovered in 2016 after more than two decade with no sightings, likely because the IUCN last assessed it in 2004. The scientific name of this species means "long-snout" and the species has been named in Spanish as the jambato hocicudo (long-snouted jambato). Common names longnose stubfoot toad, scrawny stubfoot-toad, and longnose sharlequin frog have been coined for it. Status and rediscovery The species has been classified as extinct (and as of mid-2017, remains listed as such, pending an update by the IUCN), due to huge declines probably related to the disease chytridiomycosis, climate change and habitat loss. The species was not recorded between 1989 and 2016, despite some searching in histori ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atelopus Balios
''Atelopus balios'', the Rio Pescado stubfoot toad, is a species of toad in the family Bufonidae. It is endemic to southwestern Ecuador, with records from Pacific lowlands in Azuay, Cañar, and Guayas Provinces. It is a rare species that was already suspected to be extinct, but a single specimen was discovered in 2011 by a team from Conservation International during a hunt for missing amphibians. The decline in amphibian populations is well documented. The Atelopus balios is Critically Endangered as a result of the widespread amphibian Chytridiomycosis fungus that has decimated other amphibian populations. There are only 10 known findings of the tadpole, Atelopus balios. Description Adult males measure and females in snout–vent length. The snout is pointed. The limbs are long and slender. The fingers and toes are partially webbed. The dorsum is olive green and is covered with rounded black spots that also extend to the limbs. The palms, soles, webbing, and perianal region ...

Atelopus Ignescens
''Atelopus ignescens'', the Jambato toad or Quito stubfoot toad or Jambato harlequin frog, is a species of toad in the family Bufonidae. It is endemic to the northern Andes of Ecuador. This once abundant species was believed to be extinct until its rediscovery in 2016. The specific name ''ignescens'' means "to catch fire", presumably in reference to the orange ventral color of this species. Taxonomy A closely related, perhaps undescribed species might exist in Colombia. Alexander G. Ruthven believed ''Atelopus ignescens'' to be the closest relative of the Guajira stubfoot toad ('' Atelopus carrikeri''). Later studies have indicated that its closest relative is an undescribed species from central Ecuador ( Bolívar and Chimborazo Provinces). Description Males measure on and females in snout–vent length. The body is robust with long limbs and truncate snout. The dorsal coloration is uniformly black, as is the iris. The ventral side is orange-red; the belly is lighter in col ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atelopus Bomolochos
''Atelopus bomolochos'', the Azuay stubfoot toad or Cuenca jambato frog, is a species of toad in the family Bufonidae. It is endemic to southern Ecuador and known from Cordillera Oriental (Ecuador), Cordillera Oriental in the Azuay Province, Azuay, Cañar Province, Cañar, and Loja Provinces. Description Males measure and females in snout–vent length. The Dorsum (anatomy), dorsum is yellow, yellow with brown, or yellowish green, usually with black spots on the back. The belly is yellow or orange. Habitat and conservation Its natural habitats are humid montane forest, sub-páramo, and páramo at elevations of above sea level. It breeds in streams. This formerly abundant species has nearly disappeared from its range. The decline is attributed to chytridiomycosis and habitat loss. After one last individual was observed in 2002 in the Sangay National Park, and the species was feared extinct, the species was not seen before a small population was rediscovered in 2015 near Cuenca ...

Atelopus Mindoensis
The Mindo stubfoot toad or Mindo harlequin-toad (''Atelopus mindoensis'') is a species of toad in the family Bufonidae. It is endemic to Ecuador in Pichincha, Santo Domingo and Cotopaxi Provinces. Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical moist montane forests, and rivers. It has a unique appearance and color pattern, being green and red with white speckles, and due to this it was once considered an emblematic species of the Mindo Valley. It is threatened by chytridomycosis and habitat loss, and was previously feared extinct, being last seen in Pichincha Province on May 7, 1989. It was not seen again for over 30 years, and any hopes for its survival and rediscovery were considered "unlikely", as the cloud forests A cloud forest, also called a water forest, primas forest, or tropical montane cloud forest (TMCF), is a generally tropical or subtropical, evergreen, montane, moist forest characterized by a persistent, f ...

Starry Night Toad
The starry night toad (''Atelopus arsyecue'') is a species of toad in the family Bufonidae endemic to the Sierra Nevada de Santa Marta, Colombia. Its natural habitats are sub-Andean and Andean forests, sub-páramo and páramo at above sea level. Reproduction takes place in fast-flowing rivers. It is named after its unique coloration, being largely black with white spots. It is threatened by chytridiomycosis and habitat loss and was feared extinct for over 30 years. However, its continued existence was known to the Arhuaco The Arhuaco are an indigenous people of Colombia. They are Chibchan-speaking people and descendants of the Tairona culture, concentrated in northern Colombia in the Sierra Nevada de Santa Marta.
