Atelopus Nanay Distribution
''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, with about 70% of species now considered endangered or extinct. While threatened by habitat loss, pollution, and introduced species, the primary cause of these declines appears to be the chytrid fungus '' Batrachochytrium dendrobatidis''. 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 ...

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 2 recognized species in this genus. * '' Ateleopus edentatus'' Kaga, 2016Kaga, T.

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 pristine ... [...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. Once listed as extinct by the IUCN, it was rediscovered in 2016 after more than two decade with no sightings. Names 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. Taxonomy and systematics ''Atelopus longirostris'' was species description, described by Edward Drinker Cope in 1868 based on a specimen collected by James Orton and which now appears to be lost. The Type locality (biology), type locality was stated as "Valley of Quito", but this is presumed to be erroneous. Arteaga and colleagues (2013) state that populations from Carchi Province, Carc ...

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 in the Azuay, Cañar, and Loja Provinces. Description Males measure and females in snout–vent length. The 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 Habitat destruction (also termed habitat loss or habitat reduction) occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved elsewhere, or are dead, leading to a decrease .... After one last individua ...

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, is a generally tropical or subtropical, evergreen, montane, moist forest characterized by a persistent, frequent ...

Starry Night Toad
The starry night harlequin 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. It is named after its unique coloration, being largely black with white spots. ''Atelopus arsyecue'' is primarily threatened by habitat loss, with assumptions on decline by chytridiomycosis. Coupled with the inaccessibility of the preservation that the toad calls home, the species was feared extinct for over 30 years. However, its continued existence was known to the Arhuaco community in Sogrome, who referred to the animal as ''gouna'' and considered its habitat a sacred location. In 2019, the tribe consented to collaboration with researchers and showed them the living population, marking the first scientific documentation of this species in over 30 years. Anatomy and morphology This diminutive toad is less than 5 cm (2 in) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Critically Endangered
An IUCN Red List critically endangered (CR or sometimes CE) species is one that has been categorized by the International Union for Conservation of Nature as facing an extremely high risk of extinction in the wild. As of December 2023, of the 157,190 species currently on the IUCN Red List, 9,760 of those are listed as critically endangered, with 1,302 being possibly extinct and 67 possibly extinct in the wild. The IUCN Red List provides the public with information regarding the conservation status of animal, fungi, and plant species. It divides various species into seven different categories of conservation that are based on habitat range, population size, habitat, threats, etc. Each category represents a different level of global extinction risk. Species that are considered to be critically endangered are placed within the "Threatened" category. As the IUCN Red List does not consider a species extinct until extensive targeted surveys have been conducted, species that a ...

Endangered
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching, invasive species, and climate change. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Undescribed Taxon
In taxonomy, an undescribed taxon is a taxon (for example, a species) that has been discovered, but not yet formally described and named. The various Nomenclature Codes specify the requirements for a new taxon to be validly described and named. Until such a description has been published, the taxon has no formal or official name, although a temporary, informal name is often used. A published scientific name may not fulfil the requirements of the Codes for various reasons. For example, if the taxon was not adequately described, its name is called a ''nomen nudum''. It is possible for a taxon to be "undescribed" for an extensive period of time, even if unofficial descriptions are published. An undescribed species may be referred to with the genus name, followed by "sp.", but this abbreviation is also used to label specimens or images that are too incomplete to be identified at the species level. In some cases, there is more than one undescribed species in a genus. In this case, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
