Choerophryne Gudrunae
''Choerophryne gudrunae'' is a species of frog in the family Microhylidae. It is endemic to Papua New Guinea and is only known from its type locality near Kowat in the Adelbert Range, Madang Province. Etymology This species was originally described in the genus ''Albericus'', named for Alberich, the dwarf in Scandinavian mythology and Richard Wagner's opera cycle ''Der Ring des Nibelungen''. Menzies named the species he described after Alberich's companions in the mythodology. The specific name ''gudrunae'' is derived from Gudrun. Description ''Choerophryne gudrunae'' is a comparatively small species: three unsexed individuals in the type series measure in snout–urostyle length. Later examination of these has revealed them all as males, measuring in snout–vent length. ''Choerophryne gudrunae'' shares the general appearance of other former ''Albericus'' species: brown dorsum with lighter or darker irregular mottling, warty dorsal skin, and short and road head with blunt ...

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] |
Gudrun
Gudrun ( ; non, Guðrún) or Kriemhild ( ; gmh, Kriemhilt) is the wife of Sigurd/Siegfried and a major figure in Germanic heroic legend and literature. She is believed to have her origins in Ildico, last wife of Attila the Hun, and two queens of the Merovingian dynasty, Brunhilda of Austrasia and Fredegund. In both the Continental (German) and Scandinavian traditions, Gudrun/Kriemhild is the sister of the Burgundian king Gunther/Gunnar and marries the hero Siegfried/Sigurd. Both traditions also feature a major rivalry between Gudrun and Brunhild, Gunther's wife, over their respective ranks. In both traditions, once Sigurd has been murdered, Gudrun is married to Etzel/Atli, the legendary analogue of Attila the Hun. In the Norse tradition, Atli desires the hoard of the Nibelungen, which the Burgundians had taken after murdering Sigurd, and invites them to his court; intending to kill them. Gudrun then avenges her brothers by killing Atli and burning down his hall. The Norse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Fauna Of Papua New Guinea
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] |
Amphibians Of Papua New Guinea
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 ...

Choerophryne
''Choerophryne'' is a genus of microhylid frogs, commonly known as Torricelli mountain frogs, endemic to New Guinea. These frogs are small, with the body length measured from snout to vent between 11 and 23 mm. Taxonomy and systematics The distinction between ''Choerophryne'' and the former genus ''Albericus'' was based solely on the orientation of the alary processes of the premaxillae, giving the former its distinctive snout. In 2013 a new ''Choerophryne'' species was described with an orientation intermediate between the two genera, suggesting ''Albericus'' is likely a junior synonym of ''Choerophryne''. Formal synonymisation of the two genera was suggested by Peloso and colleagues in 2016 based on molecular evidence. Etymology The genus name of the junior synonym ''Albericus'' is the Latin form of Alberich, the shape-shifting dwarf in the epic poem Nibelungenlied. Several species derive also their specific names from Nibelungenlied, e.g. ''C. siegfriedi'' from Siegfried ... [...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 ...

Sexual Selection In Amphibians
Sex is the biological distinction of an organism between male and female. Sex or SEX may also refer to: Biology and behaviour *Animal sexual behaviour **Copulation (zoology) **Human sexual activity **Non-penetrative sex, or sexual outercourse **Sex drive, a person's overall sexual drive or desire for sexual activity ** Sexual intercourse, also called copulation or coitus *Gender, the distinction between male and female or masculinity and femininity within an individual's gender identity **Sex and gender distinction *Human sexuality *Mating types, a distinction of gametes, whether in anisogamous or isogamous species * Sexing, the act of discerning the sex of an animal *Sexual reproduction, a process of combining and mixing genetic traits, associated with the generation of new individuals, by means of meiosis and fertilization ** Genetic recombination, the process of mixing genetic traits solely, occurring both in organisms with sexual or asexual reproduction Art and entertainment ...

Dorsum (anatomy)
Standard anatomical terms of location are used to unambiguously describe the anatomy of animals, including humans. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and anatomical axes. The meaning of terms that are used can change depending on whether an organism is bipedal or quadrupedal. Additionally, for some animals such as invertebrates, some terms may not have any meaning at all; for example, an animal that is radially symmetrical will have no anterior surface, but can still have a description that a part is close to the middle ("proximal") or further from the middle ("distal"). International organisations have determined vocabularies that are often used as standard vocabularies for subdisciplines of anatom ...

Type Series
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almost al ...

Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet or species epithet) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the specific the proper term for ...

Microhylidae
The Microhylidae, commonly known as narrow-mouthed frogs, are a geographically widespread family of frogs. The 683 species are in 63 genera and 11 subfamilies, which is the largest number of genera of any frog family. Evolution A molecular phylogenetic study by van der Meijden, et al. (2007) has estimated the initial internal divergence of the family Microhylidae to have taken place about 66 million years ago, or immediately after the Cretaceous extinction event. The most recent common ancestor of the Microhylidae and their closest ranoid relatives is estimated to have lived 116 million years ago in Gondwana. Description As suggested by their name, microhylids are mostly small frogs. Many species are below in length, although some species are as large as . They can be arboreal or terrestrial, and some even live close to water. The ground-dwellers are often found under leaf litter within forests, occasionally venturing out at night to hunt. The two main shapes for the microhyli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Der Ring Des Nibelungen
(''The Ring of the Nibelung''), WWV 86, is a cycle of four German-language epic music dramas composed by Richard Wagner. The works are based loosely on characters from Germanic heroic legend, namely Norse legendary sagas and the '' Nibelungenlied''. The composer termed the cycle a "Bühnenfestspiel" (stage festival play), structured in three days preceded by a ("preliminary evening"). It is often referred to as the ''Ring'' cycle, Wagner's ''Ring'', or simply ''The Ring''. Wagner wrote the libretto and music over the course of about twenty-six years, from 1848 to 1874. The four parts that constitute the ''Ring'' cycle are, in sequence: * ''Das Rheingold'' (''The Rhinegold'') * '' Die Walküre'' (''The Valkyrie'') * '' Siegfried'' * '' Götterdämmerung'' (''Twilight of the Gods'') Individual works of the sequence are often performed separately, and indeed the operas contain dialogues that mention events in the previous operas, so that a viewer could watch any of them wi ...
