Hyalinobatrachium Taylori
''Hyalinobatrachium taylori'' is a species of frog in the family Centrolenidae. Its common name is Taylor's glass frog, and in Spanish, ''ranita de cristal de Taylor''. It may represent at least two distinct species. Etymology The specific name ''taylori'' honors Edward Harrison Taylor (1889–1978), an American herpetologist. Description ''Hyalinobatrachium taylori'' has dark green dorsal ground colour with pale green spots, usually with one white fleck in the middle. Ventral skin is transparent, such that internal organs are visible. Bones are translucent green. Distribution and habitat ''Hyalinobatrachium taylori'' is found from the Guiana Shield in French Guiana, Suriname, Guyana, and southeastern Venezuela, and presumably adjacent Brazil. The type locality, " New River, Guyana", is in the region claimed by Suriname. Its natural habitats are tropical rainforest and montane Guianan forests near streams. This arboreal species lays its eggs on leaves overhanging st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
New River (South America)
The New River (Dutch: Nieuwe Rivier) is a river of South America. It forms the Western border of the Tigri Area, a disputed territory that is claimed by both Guyana and Suriname. From a Surinamese perspective it is also called the Upper Corantyne River. The river rises in the Acarai Mountains and flows, together with the Coeroeni River, to the Courantyne River. The Oronoque River is a major tributary of the New River and within the Tigri Area. It was the location of a skirmish between Guyana Police Force and a Surinamese labor camp, 15 December 1967. Military conflict broke out in August 1969 when members of the Guyana Defence Force launch an operation to clear Suriname military personnel from the area. The operation was named "Operation Climax" and was executed with maximum precision. Due to the surprise attack by the Guyana Defence Force the Suriname military ultimate decision was a hasty withdrawal, thus there were no deaths, only some POWs. This operation was one of the most ... [...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 decline ...

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 ...

IUCN
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tadpole
A tadpole is the larval stage in the biological life cycle of an amphibian. Most tadpoles are fully aquatic, though some species of amphibians have tadpoles that are terrestrial. Tadpoles have some fish-like features that may not be found in adult amphibians such as a lateral line, gills and swimming tails. As they undergo metamorphosis, they start to develop functional lungs for breathing air, and the diet of tadpoles changes drastically. A few amphibians, such as some members of the frog family Brevicipitidae, undergo direct development i.e., they do not undergo a free-living larval stage as tadpoles instead emerging from eggs as fully formed "froglet" miniatures of the adult morphology. Some other species hatch into tadpoles underneath the skin of the female adult or are kept in a pouch until after metamorphosis. Having no hard skeletons, it might be expected that tadpole fossils would not exist. However, traces of biofilms have been preserved and fossil tadpoles have ...

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] |
Borders Of Suriname
The borders of Suriname consist of land borders with three countries: Guyana, Brazil, and France (via French Guiana). The borders with Guyana and France are in dispute, but the border with Brazil has been uncontroversial since 1906. Eastern border In 1860, the question was posed from the French side, which of the two tributary rivers of the Marowijne River (also called Maroni and Marowini) was the headwater, and thus the border. A joint French-Dutch commission was appointed to review the issue. The Dutch side of the commission consisted of J.H. Baron van Heerdt tot Eversberg, J.F.A. Cateau van Rosevelt and August Kappler. Luits Vidal, Ronmy, Boudet and Dr. Rech composed the French side. In 1861 measurements were taken, which produced the following result: the Lawa had a flow rate of 35,960 m3/minute at a width of 436 m; the Tapanahony had a flow rate of 20,291 m3/minute at a width of 285 m. Thus, the Lawa River was the headwater of the Maroni River. There were no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type Locality (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almost a ...
