Rhinella Roqueana
''Rhinella roqueana'' is a species of toad in the family Bufonidae. It is found in northern Peru, eastern Ecuador ( Pastaza), Amazonian Colombia ( Amazonas and Caquetá Departments), and adjacent western Brazil. Its specific name refers to its type locality, Roque, San Martín Region, Peru. Its taxonomic position is uncertain and it is not clear how to distinguish it from other members in the '' Rhinella margaritifera'' group in the area. Description Males measure and females in snout–vent length. Habitat and conservation It is an uncommon species living in the leaf-litter of tropical lowland rainforest. 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 ... is a localized threat to this widely distributed species. For example, its type locality is mostly coff ...

Douglas Edvard Melin
Douglas Edvard Melin (4 October 1895 – 29 March 1946) was a Swedish zoologist and athlete. He was the nephew of Olof Melin. Athletic career He competed in the men's standing long jump at the 1912 Summer Olympics. He was also an avid boxer. Scientific career Melin was an all-sided zoologist who got his education at the Uppsala University Uppsala University ( sv, Uppsala universitet) is a public research university in Uppsala, Sweden. Founded in 1477, it is the oldest university in Sweden and the Nordic countries still in operation. The university rose to significance during ... and spent his career there. In 1923–26 he led an expedition to Brazil and Peru, which resulted in a large number of zoological specimens as well as ethnographic and cartographic observations. Melin was skeptical about Darwin's theories, which led to his isolation as a scientist. References External links * {{DEFAULTSORT:Melin, Douglas 1895 births 1946 deaths Swedish zoologi ...

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 al ...

Frogs Of Peru
Peru has some of the greatest biodiversity in the world. It belongs to the select group of mega diverse countries because of the presence of the Andes, Amazon rainforest, and the Pacific Ocean. It has the fourth-most tropical forests of any country and the ninth-most forest area. Natural protected areas The Constitution of Peru of 1993 recognized the natural resources and ecosystem variety of its country as a heritage. In 1900, the National System of Natural Areas that are protected by the Peruvian Government (SINANPE) was created. This entity depends on the National Institute of Natural Resources (INRENA). They also created a map of protection and preservation of historical - cultural heritage and nature. This map has 49 Natural Areas (10% of the country surface) that are preserved by the Government: 8 National Parks, 8 National Reservations, 6 National Sanctuaries, 3 Historical Sanctuaries, 4 National Forests, 6 Protection Forests, 1 Communal Reservation, 2 Hunting enclosed l ...

Amphibians Of Ecuador
Amphibians are tetrapod, four-limbed and ectothermic vertebrates of the Class (biology), class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial animal, 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 re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rhinella
''Rhinella'', commonly known as South American toads, beaked toads or Rio Viejo toads, is a genus of true toads native to Neotropical parts of Mexico, Central and South America. Additionally, the cane toad has been introduced to Australia, the Caribbean, the Philippines and elsewhere. Originally, all species of the genus ''Rhinella'' were included in the genus ''Bufo'', then they were split into the genera ''Chaunus'' and ''Rhamphophryne''. However, ''Chaunus'' and ''Rhamphophryne'' are now considered synonyms of ''Rhinella''. Etymology * ''Rhinella'' means ‘little nose’, from ''rhino- This is a list of common affixes used when scientifically naming species, particularly extinct species for whom only their scientific names are used, along with their derivations. *a-, an-: ''Pronunciation'': /ə/, /a/, /ən/, /an/.

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, intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhinella Margaritifera
The South American common toad (''Rhinella margaritifera''; also mitred toad, in Spanish sapo crestado) is a species complex of toads in the family Bufonidae. They are found throughout the Amazonian South America ( Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname, and Venezuela) and eastern Panama. It was originally believed to be a single species, but is now known to represent a complex of more than one. Its natural habitats are primary and secondary lowland, premontane and montane tropical moist forests (including terra firme and seasonally flooded forests). It is a generalist species that can also be found in disturbed areas. Member species As of 2013, there were 16 formally described species within this complex, as well as an unknown number that are yet to be recognized. *'' Rhinella acutirostris'' *'' Rhinella alata'' *''Rhinella castaneotica'' *'' Rhinella dapsilis'' *'' Rhinella hoogmoedi'' *'' Rhinella lescurei'' *'' Rhinella magnussoni'' *'' ...

Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet or species epithet) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the specific the proper term fo ...

Toad
Toad is a common name for certain frogs, especially of the family Bufonidae, that are characterized by dry, leathery skin, short legs, and large bumps covering the parotoid glands. A distinction between frogs and toads is not made in scientific taxonomy, but is common in popular culture ( folk taxonomy), in which toads are associated with drier, rougher skin and more terrestrial habitats. List of toad families In scientific taxonomy, toads include the true toads (Bufonidae) and various other terrestrial or warty-skinned frogs. Non-bufonid "toads" can be found in the families: * Bombinatoridae (fire-bellied toads and jungle toads) * Calyptocephalellidae ( helmeted water toad and false toads) * Discoglossidae ( midwife toads) * Myobatrachidae (Australian toadlets) * Pelobatidae ( European spadefoot toad) * Rhinophrynidae ( burrowing toads) * Scaphiopodidae ( American spadefoot toads) * Microhylidae ( narrowmouth toads) Biology Usually the largest of the bumps ...
