Bufo Hypomelas
''Rhaebo hypomelas'' is a species of toad in the family Bufonidae. It is endemic to Colombia and known from the Chocó region in the departments of Antioquia, Chocó, Risaralda, Valle del Cauca, and Cauca, at elevations of asl. There are also reports from Ecuador but these are not considered valid. Its natural habitats are lowland tropical moist forests. It is a terrestrial species living in leaf litter near water. It is a rare species that is threatened by 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 ....

George Albert Boulenger
George Albert Boulenger (19 October 1858 – 23 November 1937) was a Belgian-British zoologist who described and gave scientific names to over 2,000 new animal species, chiefly fish, reptiles, and amphibians. Boulenger was also an active botanist during the last 30 years of his life, especially in the study of roses. Life Boulenger was born in Brussels, Belgium, the only son of Gustave Boulenger, a Belgian public notary, and Juliette Piérart, from Valenciennes. He graduated in 1876 from the Free University of Brussels with a degree in natural sciences, and worked for a while at the Royal Belgian Institute of Natural Sciences, Brussels, as an assistant naturalist studying amphibians, reptiles, and fishes. He also made frequent visits during this time to the ''Muséum national d'Histoire naturelle'' in Paris and the British Museum in London. In 1880, he was invited to work at the Natural History Museum, then a department of the British Museum, by Dr. Albert C. L. G. Günther a ...

Amphibians Described In 1913
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] |

Rhaebo
''Rhaebo'' is a genus of true toads, family Bufonidae, from Central and South America. They are distributed from Honduras to northern South America including the Amazonian lowlands. Common name Cope toads has been suggested for them. Taxonomy The genus was removed from the synonymy of ''Bufo'' in 2006; an alternative view has been to treat it as a subgenus of ''Bufo''. At present, it is widely recognized as a genus. ''Andinophryne'', consisting of three species, was recognized as a separate genus until 2015 when it was found out that its recognition rendered ''Rhaebo'' paraphyletic. An alternative to synonymizing it with ''Rhaebo'' would have been to erect a new genus for '' Rhaebo nasicus'', but this would have caused difficulty in assigning species without molecular data to correct genus. Description ''Rhaebo'' are characterized as lacking cephalic crests, having omosternum, distinctively wide sphenethmoid, prominent and notched exoccipital condyles, and yellowish-orange sk ...

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 ...

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] |
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 ...

Risaralda Department
Risaralda () or "Rizaralde", is a landlocked department of Colombia. It is located in the western central region of the country and part of the Paisa Region. Its capital is Pereira. It was divided from the department of Caldas in 1966. Risaralda is very well known for the high quality of its coffee, and a booming industry: clothes, food, trading of goods and services. The territory is very mountainous and has many kinds of climates in a very small area. Its proximity to harbours such as Goodventure on the Pacific Ocean and to the biggest cities in Colombia – Bogota, Cali, Medellin – makes it a fast-growing economic centre. Geography Risaralda department with an area of , is located in the central sector of the central Andean region west of the country between two major poles of economic development (department of Antioquia in northern and southern Cauca Valley, extending between the central and western Cordillera), which slopes down toward the Río Cauca, a ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chocó Department
Choco Department is a department of Western Colombia known for its large Afro-Colombian population. It is in the west of the country, and is the only Colombian department to have coastlines on both the Pacific Ocean and the Atlantic Ocean. It contains all of Colombia's border with Panama. Its capital is Keebdaw. Chocó has a diverse geography, unique ecosystems and unexploited natural resources. However, its population has one of the lowest standards of living of all departments in Colombia. A major factor, cited by the government, is the rugged, montane rainforest environment, limiting any infrastructure improvements to the region. No major highway has been worked on since initial foundations were laid down in 1967. This roadway would have successfully linked Chocó to the nearest large city, Medellin, providing easier access to medical care, necessities, food, and more. Currently, depending on their location, residents of Chocó who are in a medical emergency, and who do h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
