Dendropsophinae
Dendropsophinae is a subfamily of small neotropical tree frogs in the family Hylidae. They are distributed from southern Mexico, throughout Central America, and down South America (including Trinidad) to northern Argentina and Uruguay. Removed from the synonymy of Hylinae in 2016, this taxon is not recognized in all recent reference works. The family name comes from the Greek word ''dendron'' which means "tree" and ''psophos'' which means "sound" or "noise," referring to how you are more likely to hear the frogs singing up in the trees rather than actually seeing them. They first evolved around 25.3–38.5 million years ago, splitting from Pseudinae during the Eocene 39.1–50.8 Mya and diversifying during the early Oligocene 25.3–38.5 Mya. Genera There are only two genera in the subfamily Dendropsophinae: ''Xenohyla'' is confined to only coastal Brazil, while the range of ''Dendropsophus'' is much larger. ''Xenohyla'' has 2n=24 chromosome A chromosome is a lon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pseudinae
Pseudinae is a subfamily of neotropical frogs in the family Hylidae. They are distributed all throughout the tropical and subtropical parts of South America east of the Andes, including Trinidad, all the way down to Uruguay and adjacent parts of Argentina. They are notable because despite being tree frogs, they have convergently evolved with true frogs and have lost most of their tree dwelling traits, becoming semi-aquatic or aquatic. Their name references this similarilty, with Pseudinae coming from the Greek ψεῦδος (pseudos) which means "false" or "pretending". In the wild they are preyed on by a variety of animals, including aquatic insects, spiders, and birds such as the buff-necked ibis and large-billed tern. Genera There are three genera and thirteen species within Pseudinae: These frogs have a chromosome component of 2n = 24, the exceptions being ''Scarthyla goinorum'' with 2n = 22 and ''Pseudis cardosoi'' with 2n = 28.

Hylidae
Hylidae is a wide-ranging family of frogs commonly referred to as "tree frogs and their allies". However, the hylids include a diversity of frog species, many of which do not live in trees, but are terrestrial or semiaquatic. Taxonomy and systematics The earliest known fossils that can be assigned to this family are from the Cretaceous of India and the state of Wyoming in the United States. The common name of "tree frog" is a popular name for several species of the family Hylidae. However, the name "treefrog" is not unique to this family, also being used for many species in the family Rhacophoridae. The following genera are recognised in the family Hylidae: * Subfamily Hylinae ** Tribe Cophomantini *** '' Aplastodiscus'' – canebrake treefrogs *** ''Boana'' – gladiator treefrogs *** ''Bokermannohyla'' *** ''Hyloscirtus'' *** ''Myersiohyla'' *** ''Nesorohyla'' *** '' "Hyla" nicefori'' ** Tribe Dendropsophini ***''Dendropsophus'' *** '' Julianus'' *** ''Lysapsus'' †...

Dendropsophus Bifurcus
''Dendropsophus bifurcus'' (common name: Upper Amazon treefrog) is a species of frog in the family Hylidae. It is found in the upper Amazon Basin of Bolivia, Brazil, Colombia, Ecuador, and Peru. ''Dendropsophus bifurcus'' is an abundant and widespread species that inhabits bushes in open forest and clearings. It breeds in permanent and temporary shallow ponds. Eggs are laid out of the water on leaves whereas the tadpole A tadpole is the larval stage in the biological life cycle of an amphibian. Most tadpoles are fully aquatic, though some species of amphibians have tadpoles that are terrestrial. Tadpoles have some fish-like features that may not be found i ...s develop in the water.

Synonym (taxonomy)
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia le ...

Amphibians Of Central 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 ...

Chromosome
A chromosome is a long DNA molecule with part or all of the genetic material of an organism. In most chromosomes the very long thin DNA fibers are coated with packaging proteins; in eukaryotic cells the most important of these proteins are the histones. These proteins, aided by chaperone proteins, bind to and condense the DNA molecule to maintain its integrity. These chromosomes display a complex three-dimensional structure, which plays a significant role in transcriptional regulation. Chromosomes are normally visible under a light microscope only during the metaphase of cell division (where all chromosomes are aligned in the center of the cell in their condensed form). Before this happens, each chromosome is duplicated ( S phase), and both copies are joined by a centromere, resulting either in an X-shaped structure (pictured above), if the centromere is located equatorially, or a two-arm structure, if the centromere is located distally. The joined copies are now called si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oligocene
The Oligocene ( ) is a geologic epoch of the Paleogene Period and extends from about 33.9 million to 23 million years before the present ( to ). As with other older geologic periods, the rock beds that define the epoch are well identified but the exact dates of the start and end of the epoch are slightly uncertain. The name Oligocene was coined in 1854 by the German paleontologist Heinrich Ernst Beyrich from his studies of marine beds in Belgium and Germany. The name comes from the Ancient Greek (''olÃgos'', "few") and (''kainós'', "new"), and refers to the sparsity of extant forms of molluscs. The Oligocene is preceded by the Eocene Epoch and is followed by the Miocene Epoch. The Oligocene is the third and final epoch of the Paleogene Period. The Oligocene is often considered an important time of transition, a link between the archaic world of the tropical Eocene and the more modern ecosystems of the Miocene. Major changes during the Oligocene included a global expansion o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eocene
The Eocene ( ) Epoch is a geological epoch (geology), epoch that lasted from about 56 to 33.9 million years ago (mya). It is the second epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), Era. The name ''Eocene'' comes from the Ancient Greek (''ēṓs'', "dawn") and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch. The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isotope Carbon-13, 13C in the atmosphere was exceptionally low in comparison with the more common isotope Carbon-12, 12C. The end is set at a major extinction event called the ''Grande Coupure'' (the "Great Break" in continuity) or the Eocene–Oligocene extinction event, which may be related to the impact of one or more large bolides in Popigai impact structure, Siberia and in what is now ...

Hylinae
Hylinae is a large subfamily of "tree frogs", family Hylidae. Classification The contents of this subfamily vary substantially according to the source. The Amphibian Species of the World follows the revision by Duellman and colleagues from 2016 based on molecular data and delimits the subfamily more narrowly than before, treating parts of former Hylinae as their own subfamilies. Following this classification, there were 18 genera totaling 174 species in the end of 2020. They are found North, Central, and the northmost South America, much of temperate Eurasia, Japan, and extreme northern Africa, however, only ''Hyla'' is found outside the Americas. The Wikipedia is following this classification. The AmphibiaWeb follows an older classification defining Hylinae more broadly, with several hundred species. At the end of 2020, the AmphibiaWeb lists 42 genera totaling 737 species. Amphibian Species of the World At the end of 2020, the Amphibian Species of the World includes the follo ...
