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 validi ...

Gorgona Island, Colombia
Gorgona is a Colombian island in the Pacific Ocean situated about off the Colombian Pacific coast. The island is long and across at its widest, 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 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 (Colombia) and San Blas (Panama), have the tradition of being the first settlers of the island. They left archeological remains dating back ...

Amphibians Of Ecuador
Amphibians are ectothermic, anamniote, anamniotic, tetrapod, four-limbed vertebrate animals that constitute the class (biology), class Amphibia. In its broadest sense, it is a paraphyletic group encompassing all Tetrapod, tetrapods, but excluding the amniotes (tetrapods with an amniotic membrane, such as modern reptiles, birds and mammals). All extant taxon, extant (living) amphibians belong to the monophyletic subclass (biology), subclass Lissamphibia, with three living order (biology), orders: Anura (frogs and toads), Urodela (salamanders), and Gymnophiona (caecilians). Evolved to be mostly semiaquatic, amphibians have adapted to inhabit a wide variety of habitats, with most species living in freshwater ecosystem, freshwater, wetland or terrestrial ecosystems (such as riparian woodland, fossorial and even arboreal habitats).

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 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 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 species that could also be extinct, and many of the species considered critically endangered but extant ...

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. In 2005 in Ambato a bust was unveiled to Zonia Palán Tamayo who had taught economics at the university and was notable in championing women's and union rights. 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 Uni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 in biodiversity and Abundance (ecology), species numbers. Habitat destruction is in fact the leading cause of biodiversity loss and species extinction worldwide. Humans contribute to habitat destruction through the Exploitation of natural resources, use of natural resources, agriculture, industrial production and urbanization (urban sprawl). Other activities include mining, logging and trawling. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introduced species, introduction of invasive species, ecosystem nutrient depletion, water pollution, water and noise pollution are some examples. Loss of habitat can be preceded by an initial habitat fragmentation. Fragmentation and lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 popu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat
In ecology, habitat refers to the array of resources, 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 Biophysical environment, 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 Luminous intensity, light intensity. Biotic index, Biotic factors include the availability of food and the presence or absence of Predation, predators. Every species has particular habitat requirements, habitat generalist species are able to thrive in a wide array of environmental conditions while habitat specialist species require a very limited set of factors to survive. The habitat of a species is not necessarily found in a ge ... [...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. Insects Amphibia Anura 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 fr ...

Subspecies
In Taxonomy (biology), biological classification, subspecies (: subspecies) is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (Morphology (biology), 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 as 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 name, infraspecific ranks, such as variety (botany), variety, may be named. In bacteriology and virology, under standard International Code of Nomenclature of Prokaryotes, bacterial nomenclature and virus clas ...
