Eleutherodactylus Holti
''Ischnocnema holti'' is a species of frog in the family Brachycephalidae. It is endemic to the state of Rio de Janeiro, Brazil, and is known from the Serra da Mantiqueira in Itatiaia and Serra dos Órgãos in Teresópolis. Common name Holt's robber frog has been coined for this species. Description Adult males measure and females in snout–vent length. The habitus is robust. The head is wider than long. The snout is rounded. The tympanum is distinct. The dorsum is smooth to granular, with small granulations on the sides. Discs on fingers and toes are well-developed. The dorsal coloration is variable: uniformly dark brown or gray, exhibiting green or irregularly distributed red spots, sometimes with two dark longitudinal bands running from the eyes to the posterior region, or light green with brown spots. Habitat and conservation ''Ischnocnema holti'' inhabits forests, ravines, and high-altitude grasslands. Its altitudinal range in Itatiaia is above sea level, although a m ...

Nova Iguaçu
Nova Iguaçu (, locally: or , ''New Iguaçu'') is a municipality in Rio de Janeiro state in Brazil. Location The city is named after the Iguaçu River that runs through it and empties into Guanabara Bay (not to be confused with the Iguaçu River in Paraná state, which forms the Iguaçu Falls). It is part of the Greater Rio de Janeiro metropolitan area. It was the state's second largest city in population until Mesquita was split off, and now it is the fourth largest behind São Gonçalo, Duque de Caxias and the state capital, Rio de Janeiro. It lies northwest of Rio de Janeiro, in the centre of the northern part of its metropolitan area, Baixada Fluminense. The current mayor is Rogério Lisboa ( PR). The city is the seat of the Roman Catholic Diocese of Nova Iguaçu. Nova Iguaçu has an estimated population of around 800,000 people. Although not best defined as a commuter town, it is a suburb of Rio de Janeiro under the influence of the capital – to which tens of thousand ...

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. Anurans 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 frog's ear drum works ...

Taxa Named By Doris Mable Cochran
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] |
Amphibians Of Brazil
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 Brazil
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] |
Ischnocnema
''Ischnocnema'' is a genus of frogs from eastern Brazil and north-eastern Argentina. They comprise the former ''Eleutherodactylus'' from this region, but they are closer to '' Brachycephalus'' than the "true" ''Eleutherodactylus''. Consequently, they are now placed in their own genus ''Ischnocnema'' in the family Brachycephalidae The Brachycephalidae () are a family of frogs confined to eastern and southern Brazil and northern Argentina. The family is composed of two externally quite different genera: the tiny, often (but not always) colourful and plump saddleback toads ( ....

Serra Dos Órgãos National Park
Serra dos Órgãos National Park ( pt, Parque Nacional da Serra dos Órgãos: "Organs Range") is a national park in the state of Rio de Janeiro, Brazil. It protects the Serra dos Órgãos mountain range and the water sources in the range. It was the third national park to be created in Brazil. Location The Serra dos Órgãos National Park is located about a one-hour drive from the city of Rio de Janeiro. The BR-116 highway leads through the park. The origin of the unusual name is credited to early Portuguese settlers who thought the ''ensemble'' of the hill tops resembled the pipes of organs in European cathedrals. The park is part of the larger Serra do Mar chain of mountains, and the most accepted theory about its origin is that it rose about 60 million years ago during earthquakes that caused the Andes to rise. That means it is located in a geologically unstable location, although no incident has ever been recorded in the area. The Park's area is . It has ten peaks higher th ...

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 ...

Itatiaia National Park
Itatiaia National Park ( pt, Parque Nacional do Itatiaia), established in 1937, is the oldest national park in Brazil. It is located on the border between the states of Rio de Janeiro and Minas Gerais. Location The Itatiaia National Park is the oldest national park of Brazil, created on 14 June 1937 by President Getúlio Vargas. The park is in the Mantiqueira Mountains. It covers parts of the municipalities of Itatiaia and Resende in Rio de Janeiro state, and Bocaina de Minas and Itamonte in Minas Gerais state. It is mountainous and rocky with altitudes ranging from . The highest point is the Black Needles peak ( Pico das Agulhas Negras). The higher part of the park contains the origins of 12 river basins that supply the Rio Grande (Grand River), a tributary of the Paraná River, and the Paraíba do Sul, the most important river in Rio de Janeiro state. The lower part of the park has lush Atlantic Forest vegetation and wide rivers with natural pools and waterfalls. The Pico ...

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 ...

Dorsum (anatomy)
Standard anatomical terms of location are used to unambiguously describe the anatomy of animals, including humans. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and anatomical axes. The meaning of terms that are used can change depending on whether an organism is bipedal or quadrupedal. Additionally, for some animals such as invertebrates, some terms may not have any meaning at all; for example, an animal that is radially symmetrical will have no anterior surface, but can still have a description that a part is close to the middle ("proximal") or further from the middle ("distal"). International organisations have determined vocabularies that are often used as standard vocabularies for subdisciplines of anatom ...

Teresópolis
Teresópolis (, , , ) is a Brazilian municipality located in the state of Rio de Janeiro, in a mountainous region known as ''Região Serrana''. The Serra dos Órgãos National Park lies partly within the city limits. The city is known as the home of the Brazil national football team, since it hosts CBF's training ground at Granja Comary. History Before the arrival of the Portuguese to the area where Teresópolis lies today, in the 16th century, it was inhabited by indigenous Brazilians. In the following centuries, Portuguese started buying land there. The region was also occupied by a quilombo, formed by runaway slaves coming from sugar cane plantations near Rio de Janeiro. In 1821, English citizen George March (born and raised in Portugal) established a farm there, which later became the most important settlement along the way between the court, in Rio de Janeiro, and the territory of Gerais (nowadays, the state of Minas Gerais), which led to the great improvement of agricult ...
