Vitreorana Antisthenesi
''Vitreorana antisthenesi'' is a species of frog in the family Centrolenidae. It is endemic to northern Venezuela and is known from the Venezuelan Coastal Range. Common name Aragua glass frog has been coined for it. The systematic position of this species has changed many times. It was originally described under the genus ''Centrolenella'' (a genus now synonym of ''Centrolene'') in 1963. It was later changed to the genus '' Hyalinobatrachium'' in 1991 and to '' Cochranella'' in 2006, before ending up in its current placement in the genus ''Vitreorana''. This species occurs in cloud forests and gallery forests at elevations between above sea level Height above mean sea level is a measure of the vertical distance (height, elevation or altitude) of a location in reference to a historic mean sea level taken as a vertical datum. In geodesy, it is formalized as ''orthometric heights''. The comb .... The eggs are laid on leaves overhanging streams. It is main threat is probably ...

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] |
Endemism
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Venezuelan Coastal Range
The Venezuelan Coastal Range ( es, Cordillera de la Costa or ), also known as Venezuelan Caribbean Mountain System ( es, Sistema Montañoso Caribe) is a mountain range system and one of the eight natural regions of Venezuela, that runs along the central and eastern portions of Venezuela's northern coast. The range is a northeastern extension of the Andes, and is also known as the Maritime Andes. It covers around 48,866 km2, being the 4th largest natural region in Venezuela. Geography The Coastal Range actually consists of two parallel ranges, which run east and west along the coast of the Caribbean Sea. The Cojedes River separates the western end of Coastal Range from the Cordillera de Mérida to the southeast. The range is divided into eastern and western sections by the wide bay between Cape Codera and Cumaná. Serranía del Litoral—Serranía del Interior In eastern section of the range, the parallel ranges are known as the Serranía del Litoral, which runs along the Caribbe ...

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. Males usually call from the underside of leaves. Females deposit one layer of eggs on the underside of leaves. Species As of March 2022, these species are included in the genus: * '' Hyalinobatrachium adespinosai'' Guayasamin, Vieira, Glor, and Hutter, 2019 * '' Hyalinobatrachium anachoretus'' Twomey, Delia, and Castroviejo-Fisher, 2014 * '' Hyalinobatrachium aureoguttatum ...

Cochranella
''Cochranella'' is a genus of glass frogs, family Centrolenidae. They are found in Central America from Honduras southward to the Amazonian and Andean cloud forests of Colombia, Ecuador, Peru, and Bolivia. Etymology The generic name ''Cochranella'' honors Doris Mable Cochran, an American herpetologist. Accordingly, common name Cochran frogs has been coined for the genus. Taxonomy and systematics ''Cochranella'' was first described by Edward Harrison Taylor in 1951. The current delimitation of this genus follows from the work by Juan Manuel Guayasamin and his colleagues published in 2009 (with some later adjustments). These authors remedied the polyphyly of the genus by partitioning it into several new genera. The diagnostic characteristics of the genus are the following: (1) humeral spines are absent (small spine present in ''C. litoralis''); (2) digestive tract is white (translucent in ''Cochranella nola'') and the lobed liver is covered by a transparent hepatic peritoneum; ...

Vitreorana
''Vitreorana'' is a genus of glass frogs that are native to South America, from the Atlantic Forest of Brazil and Argentina to the Amazon rainforest of Colombia and Ecuador and to the Venezuelan Coastal Range and the Guianas The Guianas, sometimes called by the Spanish loan-word ''Guayanas'' (''Las Guayanas''), is a region in north-eastern South America which includes the following three territories: * French Guiana, an overseas department and region of France * .... One way one can tell this type of glass frog from others is through their green bones, lavender-colored dorsal, and white highlighted pigment. This genus has also started to become endangered, especially in Brazil, where many ''Vitreorana'', such as '' V. eurygnatha'' due to habitat loss.

Above Sea Level
Height above mean sea level is a measure of the vertical distance (height, elevation or altitude) of a location in reference to a historic mean sea level taken as a vertical datum. In geodesy, it is formalized as ''orthometric heights''. The combination of unit of measurement and the physical quantity (height) is called "metres above mean sea level" in the metric system, while in United States customary and imperial units it would be called "feet above mean sea level". Mean sea levels are affected by climate change and other factors and change over time. For this and other reasons, recorded measurements of elevation above sea level at a reference time in history might differ from the actual elevation of a given location over sea level at a given moment. Uses Metres above sea level is the standard measurement of the elevation or altitude of: * Geographic locations such as towns, mountains and other landmarks. * The top of buildings and other structures. * Flying objects such ...

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 ...

Smallholding
A smallholding or smallholder is a small farm operating under a small-scale agriculture model. Definitions vary widely for what constitutes a smallholder or small-scale farm, including factors such as size, food production technique or technology, involvement of family in labor and economic impact. Smallholdings are usually farms supporting a single family with a mixture of cash crops and subsistence farming. As a country becomes more affluent, smallholdings may not be self-sufficient, but may be valued for the rural lifestyle. As the sustainable food and local food movements grow in affluent countries, some of these smallholdings are gaining increased economic viability. There are an estimated 500 million smallholder farms in developing countries of the world alone, supporting almost two billion people. Small-scale agriculture is often in tension with industrial agriculture, which finds efficiencies by increasing outputs, monoculture, consolidating land under big agricu ...
