Hyalinobatrachium Guairarepanense
''Hyalinobatrachium guairarepanense'' is a species of frog in the family Centrolenidae. It is endemic to Venezuela, where it is found in locations in the Coastal Range at elevations between above sea level. Its natural habitats are seasonal ( semi-deciduous) forests where it occurs along streams. The eggs are laid on leaves overhanging a stream to which the hatched larvae drop and where they continue their development. It is threatened by habitat loss. However, it has declined also in pristine habitats, suggesting that chytridiomycosis (or other disease) may be at play. Its range includes the El Ávila National Park and the Macarao National Park The Macarao National Park ( es, Parque nacional Macarao) Is a protected area with the status of a national park located in the Macarao, San Pedro and Jarillo rivers, in the north of the South American country of Venezuela.

Josefa Celsa Señaris
Josefa Celsa Señaris (born 2 November 1965) is a Venezuelan herpetologist. She has published information about frogs and she has identified new genera and species. Señaris is the director of the La Salle Foundation's Natural History Museum (Spanish: ''Museo de historia natural La Salle - MhnLS'') in Caracas. Life Señaris was born in 1965 and she obtained a degree in biology at the Central University of Venezuela and her doctorate in 2001 at the University of Santiago de Compostela in Spain. She is interested in the fauna of Venezuela, in particular the Guayana Region where table-top mountains called tepuis provide habitats for endemic plant and animal species: some amphibians are known only from a single tepuy. From a geological point of view, the tepuis have been isolated for approximately 120 million years, and it has been suggested that the tepuy habitats are a "lost world" that could support relictual populations.

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] |
Amphibians Described In 2001
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 decline ...

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] |
Hyalinobatrachium
''Hyalinobatrachium'' is a genus of glass frogs, family Centrolenidae. They are widely distributed in the Americas, from tropical Mexico to southeastern Brazil and Argentina. Taxonomy and systematics The genus is currently defined to include ''Hyalinobatrachium fleischmanni'' and its closest relatives. Its sister taxon is ''Celsiella''. Some species formerly in this genus are now in '' Vitreorana'' or '' Teratohyla''. Description ''Hyalinobatrachium'' have a bulbous liver covered by white pigment, a transparent parietal peritoneum, and lack a humeral spine in adult males. The bones are white in living animals.

El Ávila National Park
The Ávila National Park, officially known as Waraira Repano National Park for its name indigenous Cariban name, protects part of the Cordillera de la Costa Central mountain range, in the coastal region of central-northern Venezuela. The area's highest elevation is Pico Naiguatá, at above sea level. Culture & traditions El Ávila is known as "el pulmón de la ciudad", the lungs of the city, since it serves many different functions for residents of Caracas, the most basic of these being navigation: the peak of El Ávila marks the north of the city. It is home to the longest cable car ride in the world, as well as activities like running, biking, rock climbing, camping, and zip-lining. El Hotel Humboldt as well as many restaurants, including La Chivera, Casa Pakea, El Jardín de Luna, Le Galipanier, Granja Natalia and Tarahumara, are all nestled in the mountain's hills.

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 ...

Frog
A frog is any member of a diverse and largely Carnivore, carnivorous group of short-bodied, tailless amphibians composing the order (biology), order Anura (ανοὐρά, literally ''without tail'' in Ancient Greek). The oldest fossil "proto-frog" ''Triadobatrachus'' is known from the Early Triassic of Madagascar, but molecular clock, molecular clock dating suggests their split from other amphibians may extend further back to the Permian, 265 Myr, million years ago. Frogs are widely distributed, ranging from the tropics to subarctic regions, but the greatest concentration of species diversity is in tropical rainforest. Frogs account for around 88% of extant amphibian species. They are also one of the five most diverse vertebrate orders. Warty frog species tend to be called toads, but the distinction between frogs and toads is informal, not from Taxonomy (biology), taxonomy or evolutionary history. An adult frog has a stout body, protruding eyes, anteriorly-attached tongue, limb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Semi-deciduous
Semi-deciduous or semi-evergreen is a botanical term which refers to plants that lose their foliage for a very short period, when old leaves fall off and new foliage growth is starting. This phenomenon occurs in tropical and sub-tropical woody species, for example in Dipteryx odorata. Semi-deciduous or semi-evergreen may also describe some trees, bushes or plants that normally only lose part of their foliage in autumn/winter or during the dry season, but might lose all their leaves in a manner similar to deciduous trees in an especially cold autumn/winter or severe dry season (drought). See also * Brevideciduous * Evergreen * Marcescence * Hedera ''Hedera'', commonly called ivy (plural ivies), is a genus of 12–15 species of evergreen climbing or ground-creeping woody plants in the family Araliaceae, native to western, central and southern Europe, Macaronesia, northwestern Africa an ...

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] |
