Atelopus Carbonerensis
''Atelopus carbonerensis'', also known as the Venezuelan yellow frog and La Carbonera stubfoot toad (in Spanish: ''ranita amarilla de La Carbonera''), is a species of toad in the family Bufonidae. It is endemic to the Mérida Andes of Venezuela. Following an observation in 1998, it was feared extinct for nearly two decades until a single individual was sighted in 2014, followed by an observation of a mating pair in 2021. Description Adult males measure and adult females in snout–vent length. The snout is projecting. The hindlimbs are long. Dorsal coloration is yellow with brown spots around the nostrils and, occasionally, on other parts of the body. The anterior part of the belly is scarlet red. There are dorsolateral rows of tubercles and a few scattered tubercles dorsally. Habitat and conservation ''Atelopus carbonerensis'' is known from cloud forest at elevations of above sea level. Individuals have been found along streams, in which the tadpoles develop. This species wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Juan A
''Juan'' is a given name, the Spanish and Manx versions of ''John''. It is very common in Spain and in other Spanish-speaking communities around the world and in the Philippines, and also (pronounced differently) in the Isle of Man. In Spanish, the diminutive form (equivalent to ''Johnny'') is , with feminine form (comparable to ''Jane'', ''Joan'', or ''Joanna'') , and feminine diminutive (equivalent to ''Janet'', ''Janey'', ''Joanie'', etc.). Chinese terms * ( or 娟, 隽) 'beautiful, graceful' is a common given name for Chinese women. * () The Chinese character 卷, which in Mandarin is almost homophonic with the characters for the female name, is a division of a traditional Chinese manuscript or book and can be translated as 'fascicle', 'scroll', 'chapter', or 'volume'.

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, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxa Named By Juan A
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Fauna Of Venezuela
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example ''Cytisus aeolicus'' is an endemite of the Italian flora. ''Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphibians Of Venezuela
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 de ...

Atelopus
''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 decli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sierra La Culata National Park
The Sierra La Culata National Park ( es, Parque nacional Sierra de La Culata) Also Sierra de la Culata National Park is a national park of Venezuela that is located in the northeastern branch of the Venezuelan Andes, in the states Mérida and Trujillo. It was decreed a national park on December 7, 1989. It has a high mountain climate, with temperatures ranging between , and its surface area is . The vegetation is characterized by the presence of numerous species of frailejones, shrubs such as ericaceae and melastomataceae; ferns and numerous mosses, liver lichens and fungi. The tree of the zone is the Coloradito. This park houses species such as the Jaguar, the Spectacled bear, the Armadillo, the Loach, the Andean condor, and amphibians such as the nurse frog (sapito niñera).

Mérida (state)
The State of Mérida commonly known simply as Mérida ( es, Estado Bolivariano de Mérida, ) is one of the 23 states of Venezuela. The state capital is Mérida, in the Libertador Municipality. Located in the Western Andean Region, Mérida State covers a total surface area of , making it the fifteenth-largest in Venezuela. In 2011, had a census population of 828,592, the fourteenth most populous. History Pre-Colonial According to recent studies in archaeology, history and anthropology, The Andean region seems to have been inhabited since very remote times (perhaps several thousand years) by unknown groups that have left very few traces. Then, around our era, another ethnic group of great cultural importance arrives in the region, perhaps of Chibcha origin, since they share with these their mythology, funeral and settlement patterns, housing construction, agricultural techniques, etc. When the Spanish arrive in the Andean Cordillera it will be with this second group you wil ...

Páramo El Tambor
Páramo () can refer to a variety of alpine tundra ecosystems located in the Andes Mountain Range, South America. Some ecologists describe the páramo broadly as "all high, tropical, montane vegetation above the continuous timberline". A narrower term classifies the páramo according to its regional placement in the northern Andes of South America and adjacent southern Central America. The páramo is the ecosystem of the regions above the continuous forest line, yet below the permanent snowline. It is a "Neotropical high mountain biome with a vegetation composed mainly of giant rosette plants, shrubs and grasses". According to scientists, páramos may be "evolutionary hot spots", that meaning that it's among the fastest evolving regions on Earth. Location The Northern Andean Páramo global ecoregion includes the Cordillera Central páramo (Ecuador, Peru), Santa Marta páramo (Colombia), Cordillera de Merida páramo (Venezuela) and Northern Andean páramo (Colombia, Ecuador) ter ...

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 amphibi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of Taxonomy (biology), 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 reproduction, produce Fertility, fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), 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 binomial nomenclature, 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 specifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
