Pristimantis
''Pristimantis'' is a very specious genus of frogs distributed in the southern Caribbean islands (Lesser Antilles) and in Central and South America from Honduras to northern Argentina and southern Brazil. With 617 described species (as of February 2025), the genus has more species than any other vertebrate genus. Many of these species genus are endemic to the Northwestern Andean montane forests ecoregion in north-western South America. Etymology From the Greek πρίστις (serrated) and μάντις (arboreal frog). Taxonomy Placement of this genus has varied greatly. ''Pristimantis'' was long included in the massive genus '' Eleutherodactylus'', and considered part of the family Leptodactylidae. Currently, the genus is placed in the family Strabomantidae The Strabomantidae, sometimes called cloud forest landfrogs, are a family of frogs native to South America. These frogs lack a free-living larval stage and hatch directly into miniature "froglets". This family includ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Northwestern Andean Montane Forests
The Northwestern Andean montane forests (NT0145) is an ecoregion on the Andes mountains in the west of Colombia and Ecuador. Both flora and fauna are highly diverse due to effect of ice ages when the warmer climate zones were separated and the cooler ones combined, and interglacial periods when the reverse occurred. Because the environment is hospitable to humans, the habitat has been drastically modified by farming and grazing since the Pre-Columbian era. Geography Location The Northwestern Andean montane forests ecoregion extends along the Cordillera Occidental (Western Range) of the Andes in Colombia and the Cordillera Occidental of Ecuador. It covers an area of . In the extreme north the ecoregion merges into the Magdalena–Urabá moist forests ecoregion. Through most of its length in Colombia it transitions on the west into the Chocó–Darién moist forests and on the east into the Cauca Valley montane forests. The higher levels of the ecoregion give way to Northern And ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Strabomantidae
The Strabomantidae, sometimes called cloud forest landfrogs, are a family of frogs native to South America. These frogs lack a free-living larval stage and hatch directly into miniature "froglets". This family includes '' Pristimantis'', the most speciose genus of any vertebrate. Based on molecular dating, the Holoadeninae in particular appears to have originated in the Eocene. The Oligocene-Miocene transition was also found to be important to their biogeographical history. However, the lack of Holoadeninae fossils and limited nucleotide Nucleotides are Organic compound, organic molecules composed of a nitrogenous base, a pentose sugar and a phosphate.

Frog
A frog is any member of a diverse and largely semiaquatic group of short-bodied, tailless amphibian vertebrates composing the order (biology), order Anura (coming from the Ancient Greek , literally 'without tail'). Frog species with rough skin texture due to wart-like parotoid glands tend to be called toads, but the distinction between frogs and toads is informal and purely cosmetic, not from taxonomy (biology), taxonomy or evolutionary history. Frogs are widely distributed, ranging from the tropics to subarctic regions, but the greatest concentration of species diversity is in tropical rainforest and associated wetlands. They account for around 88% of extant amphibian species, and are one of the five most diverse vertebrate orders. The oldest fossil "proto-frog" ''Triadobatrachus'' is known from the Early Triassic of Madagascar (250Myr, million years ago), but molecular clock, molecular clock dating suggests their divergent evolution, divergence from other amphibians may exte ...

Family (biology)
Family (, : ) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...

Amphibians Of South America
Amphibians are ectothermic, anamniotic, four-limbed vertebrate animals that constitute the class Amphibia. In its broadest sense, it is a paraphyletic group encompassing all tetrapods, but excluding the amniotes (tetrapods with an amniotic membrane, such as modern reptiles, birds and mammals). All extant (living) amphibians belong to the monophyletic subclass Lissamphibia, with three living orders: Anura (frogs and toads), Urodela (salamanders), and Gymnophiona (caecilians). Evolved to be mostly semiaquatic, amphibians have adapted to inhabit a wide variety of habitats, with most species living in freshwater, wetland or terrestrial ecosystems (such as riparian woodland, fossorial and even arboreal habitats). Their life cycle typically starts out as aquatic larvae with gills known as tadpoles, but some species have developed behavioural adaptations to bypass this. Young amphibians generally undergo metamorphosis from an aquatic larval form with gills to an air-breathing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Comparison Of Pristimantis Erythros With Another Species
Comparison or comparing is the act of evaluating two or more things by determining the relevant, comparable characteristics of each thing, and then determining which characteristics of each are similar to the other, which are different, and to what degree. Where characteristics are different, the differences may then be evaluated to determine which thing is best suited for a particular purpose. The description of similarities and differences found between the two things is also called a comparison. Comparison can take many distinct forms, varying by field: To compare things, they must have characteristics that are similar enough in relevant ways to merit comparison. If two things are too different to compare in a useful way, an attempt to compare them is colloquially referred to in English as "comparing apples and oranges." Comparison is widely used in society, in science and the arts. General usage Comparison is a natural activity, which even animals engage in when decidin ...

Leptodactylidae
The southern frogs form the Leptodactylidae, a name that comes from Greek meaning a bird or other animal having slender toes. They are a diverse family of frogs that most likely diverged from other hyloids during the Cretaceous. The family has undergone major taxonomic revisions in recent years, including the reclassification of the former subfamily Eleutherodactylinae into its own family the Eleutherodactylidae; the Leptodactylidae now number 206 species in 13 genera distributed throughout Mexico, the Caribbean, and Central and South America. The family includes terrestrial, burrowing, aquatic, and arboreal members, inhabiting a wide range of habitats. Several of the genera within the Leptodactylidae lay their eggs in foam nests. These can be in crevices, on the surface of water, or on forest floors. These foam nests are some of the most varied among frogs. When eggs hatch in nests on the forest floor, the tadpoles remain within the nest, without eating, until metamorphosis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
