Rheobates
''Rheobates'' is a genus of frogs in the family Aromobatidae. It is endemic to Colombia. These are cryptically coloured frogs with extensive toe webbing. The name ''Rheobates'' is derived from the Greek words ''rheo'' (stream, current) and βάτης ''bátēs'' (a walker), in reference to the riparian habitat of the type species '' Rheobates palmatus''. They are associated with streams in sub-Andean forests and foothills of the Andes The Andes, Andes Mountains or Andean Mountains (; ) are the longest continental mountain range in the world, forming a continuous highland along the western edge of South America. The range is long, wide (widest between 18°S – 20°S ... at low to medium altitudes. Species There are currently two species: * '' Rheobates palmatus'' (Werner, 1899) * '' Rheobates pseudopalmatus'' (Rivero and Serna, 2000) The validity of ''Rheobates pseudopalmatus'' has been questioned, whereas ''Rheobates palmatus'' may represent a species complex.

Rheobates Palmatus
''Rheobates palmatus'' is a species of frog in the family Aromobatidae. It is the type species of genus ''Rheobates'' erected in 2006. Its common name is palm rocket frog. It is endemic to Colombia. It is considered to be part of a species complex. Description ''Rheobates palmatus'' has cryptic, brown or gray dorsal colouration and posteriorly granular skin texture. Toe webbing is extensive. It is also distinguishable by its large size. Its tadpoles are also large and are a uniform colour without markings. Distribution and habitat ''Rheobates palmatus'' is endemic to the Colombian Andes and is found on both sides of the Cordillera Oriental and on the eastern side of the Cordillera Central range at heights of above sea level. As it has not been found higher than , it is effectively divided into three distinct populations as those on the two slopes of the Cordillera Oriental are separated by a continuous, high altitude ridge. It has been found that the vocalisations of the mal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aromobatidae
The Aromobatidae are a family of frogs native to Central and South America. They are sometimes referred to as cryptic forest frogs or cryptic poison frogs. They are the sister taxon of the Dendrobatidae, the poison dart frogs, but are not as toxic as most dendrobatids are. Taxonomy The Aromobatidae were separated from the Dendrobatidae only in 2006, and some sources continue to treat these frogs as part of the Dendrobatidae. However, their position as the sister taxa is well supported, and the question is primarily about whether they should be ranked as a family or a subfamily. The validity of subfamilies within the Aromobatidae is also unsettled. Some evidence points to paraphyly of at least the subfamily Anomaloglossinae, and genus ''Allobates'', largely because of the uncertain placement of ''Allobates olfersioides''. Some species are reported to have a skunk like odor. This strong odor is secreted through the skin but theses frogs are not toxic. This strong odor is used as a ...

Franz Werner
Franz Josef Maria Werner (15 August 1867 in Vienna – 28 February 1939 in Vienna) was an Austrian zoologist and explorer. Specializing as a herpetologist and entomologist, Werner described numerous species and other taxa of frogs, snakes, insects, and other organisms. His father introduced him at age six to reptiles and amphibians. A brilliant student, he corresponded often with George Albert Boulenger (1858–1937) and Oskar Boettger (1844–1910) who encouraged his studies with these animals. Werner obtained his doctorate in Vienna in 1890 and then after spending a year in Leipzig, began to teach at the Vienna Institute of Zoology. In 1919, he became tenured as a professor, maintaining this title until his retirement in 1933. Although working close to the Vienna Natural History Museum, he could not use their herpetological collections, after the death of its director, Franz Steindachner (1834–1919), who did not like Werner, and had barred him from accessing the collec ...

Darrel Frost
Darrel Richmond Frost (born 1951) is an American herpetologist and systematist. He was previously head curator of herpetology at the American Museum of Natural History, as well as president of both the Society for the Study of Amphibians and Reptiles (1998) and the American Society of Ichthyologists and Herpetologists (2006). Four taxa are named in his honor: the toad genus '' Frostius'' (which includes Frost's toad), the tree frog '' Dendropsophus frosti'', Darrel's chorus frog ''Microhyla darreli'', and Frost's arboreal alligator lizard '' Abronia frosti''. Life Frost became interested in animals after witnessing his father kill a rattlesnake at the age of four. He earned a B.S. in Biology from the University of Arizona in 1973, an M.S. in Zoology from Louisiana State University in 1978, and a Ph.D. in Ecology and Systematics from the University of Kansas in 1988. He became an adjunct professor at Columbia University in 2000. In 1990, Frost was appointed Assistant Curator of H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
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] |
Endemic
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.

Andes
The Andes, Andes Mountains or Andean Mountains (; ) are the longest continental mountain range in the world, forming a continuous highland along the western edge of South America. The range is long, wide (widest between 18°S – 20°S latitude), and has an average height of about . The Andes extend from north to south through seven South American countries: Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile, and Argentina. Along their length, the Andes are split into several ranges, separated by intermediate depressions. The Andes are the location of several high plateaus—some of which host major cities such as Quito, Bogotá, Cali, Arequipa, Medellín, Bucaramanga, Sucre, Mérida, El Alto and La Paz. The Altiplano plateau is the world's second-highest after the Tibetan plateau. These ranges are in turn grouped into three major divisions based on climate: the Tropical Andes, the Dry Andes, and the Wet Andes. The Andes Mountains are the highest m ...

Amphibians Of South America
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 ...
