Stereocyclops Incrassatus
''Stereocyclops incrassatus'' is a species of frog in the family Microhylidae. It is endemic to eastern Brazil and is known from Pernambuco and Alagoas in the north and then southward through Bahia to Minas Gerais and Espírito Santo. Earlier records from São Paulo state are now recognized as ''Stereocyclops parkeri''. Common name Brazilian dumpy frog has been coined for this species. Description The holotype, an adult male, measures in snout–vent length (SVL). In a population in Linhares observed at the time of breeding, adult males measured and females in SVL. The body is very stout. The snout is short, rounded in dorsal view but more acute in profile. The eyes are small and the tympanum is indistinct. The fingers are fairly long and have no webbing. The toes are long and have basal webbing. Skin is smooth except for a few granules on the sides. Habitat and conservation Its natural habitats are primary and secondary forests at elevations below . It is a nocturnal specie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edward Drinker Cope
Edward Drinker Cope (July 28, 1840 – April 12, 1897) was an American zoologist, paleontologist, comparative anatomist, herpetologist, and ichthyologist. Born to a wealthy Quaker family, Cope distinguished himself as a child prodigy interested in science; he published his first scientific paper at the age of 19. Though his father tried to raise Cope as a gentleman farmer, he eventually acquiesced to his son's scientific aspirations. Cope married his cousin and had one child; the family moved from Philadelphia to Haddonfield, New Jersey, although Cope would maintain a residence and museum in Philadelphia in his later years. Cope had little formal scientific training, and he eschewed a teaching position for field work. He made regular trips to the American West, prospecting in the 1870s and 1880s, often as a member of United States Geological Survey teams. A personal feud between Cope and paleontologist Othniel Charles Marsh led to a period of intense fossil-finding competit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Holotype
A holotype is a single physical example (or illustration) of an organism, known to have been used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of several examples, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN, the definitions of types are similar in intent but not identical in terminology or underlying concept. For example, the holotype for the butterfly '' Plebejus idas longinus'' is a preserved specimen of that subspecies, held by the Museum of Comparative Zoology at Harvard University. In botany, an isotype is a duplicate of the holotype, where holotype and isotypes are often pieces from the same individual plant or samples from the same gathering. A holotype is not necessaril ...

Taxa Named By Edward Drinker Cope
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 int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Frogs 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 t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stereocyclops
''Stereocyclops'' (common name: Brazilian dumpy frogs) is a small genus of Microhylidae, microhylid frogs. It is endemic to the Atlantic forest of eastern Brazil. Molecular phylogeny suggests that it is sister taxon to the clade containing ''Dasypops'' and ''Myersiella''. Description ''Stereocyclops'' can be defined by features of its osteology. In the skull, palatine bone is present, as is the posterior part of prevomer. The clavicle is fully developed and long. Furthermore, the dorsal coloration is light and sharply separated from the dark ventrum by a light line. The head is flattened and the mouth is relatively large. Notice, however, that at the time of this description, the genus was monotypic and ''Hyophryne'' was considered a separate genus; a thorough morphological study of the genus as presently understood is lacking. Beheavior One species, ''Stereocyclops parkeri'', is known to show defensive behavior that may enhance its cryptic appearance, giving an impression of a c ...

Rio Doce State Park
The Rio Doce State Park ( pt, Parque Estadual do Rio Doce) is a state park in the state of Minas Gerais, Brazil. It protects a large remnant of Atlantic Forest, and includes a system of lagoons rich in species of native fish. Location The Rio Doce State Park is in the southwest of Minas Gerais, from Belo Horizonte, in the Vale do Aço region. It is divided between the municipalities of Marliéria, Dionísio and Timóteo. It has an area of . The Doce River forms the eastern boundary of the park, and its tributary the Piracicaba River forms the northern boundary. The park protects part of the third largest lake system in Brazil after the Amazon and the Pantanal of Mato Grosso. This is a system of forty natural lagoons including the Lagoa Dom Helvécio, with a depth of up to . The lake system is at an altitude of . The lakes are above the river, and are not connected with the river system. History Creation of the park was first suggested in the early 1930s by Dom Helvécio G ...

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] |
Nocturnal Animal
Nocturnality is an animal behavior characterized by being active during the night and sleeping during the day. The common adjective is "nocturnal", versus diurnal meaning the opposite. Nocturnal creatures generally have highly developed senses of hearing, smell, and specially adapted eyesight. Some animals, such as cats and ferrets, have eyes that can adapt to both low-level and bright day levels of illumination (see metaturnal). Others, such as bushbabies and (some) bats, can function only at night. Many nocturnal creatures including tarsiers and some owls have large eyes in comparison with their body size to compensate for the lower light levels at night. More specifically, they have been found to have a larger cornea relative to their eye size than diurnal creatures to increase their : in the low-light conditions. Nocturnality helps wasps, such as ''Apoica flavissima'', avoid hunting in intense sunlight. Diurnal animals, including squirrels and songbirds, are act ...

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] |
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 wo ...

Linhares
Linhares is the name of a municipality in the state of Espírito Santo, Brazil, north of the state capital, Vitória. It is the largest municipality by area in the state, at 9,501.6 km², and has a population of 176,688 people (2020). The municipality is named in honor of D. Rodrigo de Souza Coutinho, Count of Linhares, who was a minister in the Brazilian government in the first two decades of the 19th century. The city took international knowledge, being the residence of Miss Gay Brazil 2013 and 2014. History The area today known as Linhares was once inhabited by the Botocudo. The town, founded by Europeans on August 22, 1800 was destroyed by the Indians during a war in 1809. The area was visited by Brazilian Emperor Dom Pedro II in 1860. An island he set foot on is still known as the Emperor's Island. Linhares became a municipality in 1945, when it was detached from the municipality of Colatina. Economy The economy of Linhares is mostly based on commerce, agricultur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stereocyclops Parkeri
''Stereocyclops parkeri'' is a species of frog in the family Microhylidae. It is endemic to southeastern Brazil and known from the southwestern part of the state of Rio de Janeiro and from Ilha de São Sebastião ("Ilhabela"), São Paulo state. For a period it was treated as a synonym of '' Stereocyclops incrassatus'', but is now recognized as valid species. Etymology The specific name ''parkeri'' honors Hampton Wildman Parker, an English zoologist and herpetologist. It is sometimes known with the common name the Parker's Brazilian dumpy frog. Description ''Stereocyclops parkeri'' measure about in snout–vent length. The appearance is cryptic. Behavior ''Stereocyclops parkeri'' show defensive behavior that may enhance its cryptic appearance, giving an impression of a casually dislodged leaf: when disturbed, the individual makes a short leap, landing with its legs stretched backwards. It will then remain still, sometimes as long as 30 minutes, although it may also move a litt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
