Atelopus Elegans
The elegant stubfoot toad or Pacific jambato frog (''Atelopus elegans'') is a species of toad in the family Bufonidae found in lowlands and Andean slopes of northwest Ecuador to asl and on the Gorgona Island, off southwest coast of Colombia. It was described by George Albert Boulenger in 1882 based on a specimen collected by Edward Whymper. It is known in Spanish as ''rana jambato del Pacífico'' or simply ''jambato del Pacífico''. History and taxonomy The species was described by George Albert Boulenger in 1882 based on a female specimen collected by Edward Whymper during his expedition to Ecuador in 1879–1880. Toads from the Gorgona Island were described by Thomas Barbour in 1905 as a new species, ''Atelopus gracilis'', but later authors have considered them to be the same species as ''Atelopus elegans''. Analyses using molecular methods have not included ''Atelopus elegans'', and the colour difference between the mainland and Gorgona populations suggests that the v ...

Gorgona Island, Colombia
Gorgona is a Colombian island in the Pacific Ocean situated about off the Colombian Pacific coast. The island is long and wide, with a maximum height of and a total area of . Gorgona is separated from the continent by a deep underwater depression. Administratively the island is part of the Municipality of Guapi, Cauca, Guapí in the Department of Cauca. Gorgona functioned as a prison from 1959 until 1984 when it was turned into a National Natural Park. The island, noted for its many endemic species and unique ecosystems, was established as Gorgona Island National Park in 1985, in order to preserve its richly varied wildlife of the sub-tropical forest and the coral reefs offshore. History Early settlements Gorgona was first inhabited by people possibly associated with the Tumaco-Tolita culture. The indigenous Kuna or Cuna of Urabá Antioquia, Urabá (Colombia) and San Blas (Panama), have the tradition of being the first settlers of the island. They left archeological remains ...

Amphibians Of Ecuador
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] |

Atelopus
''Atelopus'' is a large genus of Bufonidae, commonly known as harlequin frogs or toads, from Central America, 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 animal, diurnal. Most species are associated with mid-to-high elevation streams. This genus has been greatly affected by Decline in amphibian populations, 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 IUCN Red List, 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 taxon, 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.

Pontificia Universidad Católica Del Ecuador
The Pontificia Universidad Católica del Ecuador (PUCE) (English: ''Pontifical Catholic University of Ecuador'') is a Pontifical Catholic university founded in 1946 in Quito, Ecuador. History The university opened in the fall of 1946, with Carlos María de la Torre, archbishop of Quito, officiating. Aurelio Espinosa Pólit of the Society of Jesus (Jesuits) was the first rector. That fall there were 54 students and jurisprudence was the single faculty. Pope Francis visited the campus of PUCE on his trip to South America in July 2015. Location The principal campus of the university is in Quito. Other campuses are in Ambato (established in 1982), Esmeraldas (1981), Ibarra (1976), Santo Domingo de los Colorados (1996), and a regional campus in the province of Manabí (1993). The campus in Cuenca later became the Universidad del Azuay. All branches follow the National System PUCE.

Habitat Loss
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...

Chytridiomycosis
Chytridiomycosis ( ) is an infectious disease in amphibians, caused by the chytrid fungi ''Batrachochytrium dendrobatidis'' and ''Batrachochytrium salamandrivorans''. Chytridiomycosis has been linked to dramatic population declines or extinctions of amphibian species in western North America, Central America, South America, eastern Australia, east Africa (Tanzania), and Dominica and Montserrat in the Caribbean. Much of the New World is also at risk of the disease arriving within the coming years. The fungus is capable of causing sporadic deaths in some amphibian populations and 100% mortality in others. No effective measure is known for control of the disease in wild populations. Various clinical signs are seen by individuals affected by the disease. A number of options are possible for controlling this disease-causing fungus, though none has proved to be feasible on a large scale. The disease has been proposed as a contributing factor to a global decline in amphibian populat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tympanum (anatomy)
The tympanum is an external hearing structure in animals such as mammals, birds, some reptiles, some amphibians and some insects. Using sound, vertebrates and many insects are capable of sensing their prey, identifying and locating their predators, warning other individuals, and locating potential mates and rivals by hearing the intentional or unintentional sounds they make. In general, any animal that reacts to sounds or communicates by means of sound, needs to have an auditory mechanism. This typically consists of a membrane capable of vibration known as the tympanum, an air-filled chamber and sensory organs to detect the auditory stimuli. Anurans In frogs and toads, the tympanum is a large external oval shape membrane made up of nonglandular skin. It is located just behind the eye. It does not process sound waves; it simply transmits them to the inner parts of the amphibian's ear, which is protected from the entry of water and other foreign objects. A frog's ear drum works ...

Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
