Ceiba Stream Frog
The Ceiba stream frog (''Atlantihyla spinipollex'') is a species of frog in the family Hylidae endemic to Honduras. Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical moist montane forests, and rivers. It is threatened by habitat loss. In 2020, a population of frogs believed to be the Ceiba stream frog was described as a new species, ''Atlantihyla melissa ''Atlantihyla melissa'' is a species of frog in the family Hylidae, endemic to Honduras. It has been observed between 780 and 1680 meters above sea level in the Cordillera Nombre de Dios mountains. Its known habitat is contained within the Ref ...''.

Karl Patterson Schmidt
Karl Patterson Schmidt (June 19, 1890 – September 26, 1957) was an American herpetologist. Family Schmidt was the son of George W. Schmidt and Margaret Patterson Schmidt. George W. Schmidt was a German professor, who, at the time of Karl Schmidt's birth, was teaching in Lake Forest, Illinois. His family left the city in 1907 and settled in Wisconsin. They worked on a farm near Stanley, Wisconsin, where his mother and his younger brother died in a fire on August 7, 1935. The brother, Franklin J. W. Schmidt, had been prominent in the then-new field of wildlife management. Karl Schmidt married Margaret Wightman in 1919, and they had two sons, John and Robert. Education In 1913, Schmidt entered Cornell University to study biology and geology. In 1915, he discovered his preference for herpetology during a four-month training course at the Perdee Oil Company in Louisiana. In 1916, he received the degree of Bachelor of Arts and made his first geological expedition to Santo Do ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atlantihyla Melissa
''Atlantihyla melissa'' is a species of frog in the family Hylidae, endemic to Honduras. It has been observed between 780 and 1680 meters above sea level in the Cordillera Nombre de Dios mountains. Its known habitat is contained within the Refugio de Vida Silvestre Texiguat. Appearance The adult male frog measures 30.4 - 38.8 mm in snout-vent length and the adult female frog is 30.9 - 43.9 mm long. This frog can be any of several colors. Some frogs have spots and some do not. Most frogs have a ventrolateral stripe that can be pale to bright yellow. This frog exhibits considerable sexual dimorphism but scientists note large amounts of inter-individual variation as well. Adult male frogs can have salmon colored eyes or red eyes. Adult female frogs have green eyes or brown eyes. Habitat These frogs live in riparian habitats with fast-moving water and rocky beds with pools nearby. At night, scientists have observed these frogs sitting on plants that hang over t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphibians Described In 1936
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 ...

Endangered Fauna Of North America
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are considered when assessing the stat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Fauna Of Honduras
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 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Atlantihyla
''Atlantihyla'' is a genus of frogs in the family Hylidae. It is endemic to Central America, specifically to Honduras and Guatemala. The generic name refers to its distribution on the Atlantic side of the isthmus (from ''Atlantis''+''hyla''). The members of the genus are known as stream frogs. Taxonomy The genus was established based on molecular data in a revision of the subfamily Hylinae by Julián Faivovich and colleagues in 2018. In order to obtain a monophyletic '' Ptychohyla'', Faivovich and colleagues moved two former ''Ptychohyla'' species to ''Atlantihyla'' and four former ''Ptychohyla'' species to '' Quilticohyla.'' ''Atlantihyla'' has a sister group relationship to a poorly-supported clade that includes ''Bromeliohyla'', '' Duellmanohyla'', and ''Quilticohyla''. A third ''Atlantihyla'' species was described in 2020. Description The only, tentative phenotypic synapomorphy of this genus is the presence of a well-defined ventrolateral white stripe.

Sister Species
In phylogenetics, a sister group or sister taxon, also called an adelphotaxon, comprises the closest relative(s) of another given unit in an evolutionary tree. Definition The expression is most easily illustrated by a cladogram: Taxon A and taxon B are sister groups to each other. Taxa A and B, together with any other extant or extinct descendants of their most recent common ancestor (MRCA), form a monophyletic group, the clade AB. Clade AB and taxon C are also sister groups. Taxa A, B, and C, together with all other descendants of their MRCA form the clade ABC. The whole clade ABC is itself a subtree of a larger tree which offers yet more sister group relationships, both among the leaves and among larger, more deeply rooted clades. The tree structure shown connects through its root to the rest of the universal tree of life. In cladistic standards, taxa A, B, and C may represent specimens, species, genera, or any other taxonomic units. If A and B are at the same taxonomic ...

Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...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] |
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 ...
