Electron (bird)
''Electron'' is a genus of the motmots, a family of Neotropical near passerine birds. The genus has two species: Both inhabit humid evergreen tropical forest. Both occur in Central America, and the broad-billed motmot occurs in a large region of South America as well. They are distinguished from other motmots by their much wider bills. The rackets on their tails are less dramatic than those of many other motmot species and may be absent. The species are very similar except in adult plumage (but the adult keel-billed resembles the juvenile broad-billed). A mixed pair apparently courting has been observed (Howell and Webb 1995). The name ''Electron'' is a Latinization of the Ancient Greek word for amber, and can mean "bright" in scientific names (Jaeger 1978). The name was given 46 years before an elementary particle was named electron The electron ( or ) is a subatomic particle with a negative one elementary electric charge. Electrons belong to the first generation of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Broad-billed Motmot
The broad-billed motmot (''Electron platyrhynchum'') is a fairly common Central and South American bird of the Momotidae family. They are nonmigratory, sedentary birds that are most frequently seen in singles or pairs. There exist six subspecies of the broad-billed motmot. Description At about 12 inches long, the broad-billed motmot is one of the smallest members of the family Momotidae. These birds weigh 60 grams on average. They have dark eyes and feet. Most of its upper body, including its head, neck and chest, is a cinnamon-rufous colour. There is a black patch on either side of its head that covers the cheeks and auricular area, as well as one on the centre of its chest. The lower half of its body is more greenish above and becomes more blueish below. The broad-billed motmot has a long tail that gradually changes from blue to black. It also has two racquet-shaped central feathers are much longer than the rest. As its name suggests, the broad-billed motmot has a broad, fl ...

Taxa Named By Johannes Von Nepomuk Franz Xaver Gistel
In biology, a taxon (back-formation from ''Taxonomy (biology), taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular Taxonomic rank, ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's Linnaean taxonomy, system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard de Jussieu, Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of bio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Electron
The electron ( or ) is a subatomic particle with a negative one elementary electric charge. Electrons belong to the first generation of the lepton particle family, and are generally thought to be elementary particles because they have no known components or substructure. The electron's mass is approximately 1/1836 that of the proton. Quantum mechanical properties of the electron include an intrinsic angular momentum ( spin) of a half-integer value, expressed in units of the reduced Planck constant, . Being fermions, no two electrons can occupy the same quantum state, in accordance with the Pauli exclusion principle. Like all elementary particles, electrons exhibit properties of both particles and waves: They can collide with other particles and can be diffracted like light. The wave properties of electrons are easier to observe with experiments than those of other particles like neutrons and protons because electrons have a lower mass and hence a longer de Broglie wavele ...

Amber
Amber is fossilized tree resin that has been appreciated for its color and natural beauty since Neolithic times. Much valued from antiquity to the present as a gemstone, amber is made into a variety of decorative objects."Amber" (2004). In Maxine N. Lurie and Marc Mappen (eds.) ''Encyclopedia of New Jersey'', Rutgers University Press, . Amber is used in jewelry and has been used as a healing agent in folk medicine. There are five classes of amber, defined on the basis of their chemical constituents. Because it originates as a soft, sticky tree resin, amber sometimes contains animal and plant material as inclusions. Amber occurring in coal seams is also called resinite, and the term ''ambrite'' is applied to that found specifically within New Zealand coal seams. Etymology The English word ''amber'' derives from Arabic (ultimately from Middle Persian ''ambar'') via Middle Latin ''ambar'' and Middle French ''ambre''. The word was adopted in Middle English in the 14th century ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ancient Greek
Ancient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Dark Ages (), the Archaic period (), and the Classical period (). Ancient Greek was the language of Homer and of fifth-century Athenian historians, playwrights, and philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Epic and Classical periods of the language. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regarded as a separate historical stage, although its earliest form closely resembles Attic Greek and its latest form approaches Medieval Greek. There were several regional dialects of Ancient Greek, of which Attic Greek developed into Koine. Dia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Latin
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four verb conjuga ...

South America
South America is a continent entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a relatively small portion in the Northern Hemisphere at the northern tip of the continent. It can also be described as the southern subregion of a single continent called America. South America is bordered on the west by the Pacific Ocean and on the north and east by the Atlantic Ocean; North America and the Caribbean Sea lie to the northwest. The continent generally includes twelve sovereign states: Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Guyana, Paraguay, Peru, Suriname, Uruguay, and Venezuela; two dependent territories: the Falkland Islands and South Georgia and the South Sandwich Islands; and one internal territory: French Guiana. In addition, the ABC islands of the Kingdom of the Netherlands, Ascension Island (dependency of Saint Helena, Ascension and Tristan da Cunha, a British Overseas Territory), Bouvet Island ( dependency of Norway), Pa ...

Central America
Central America ( es, América Central or ) is a subregion of the Americas. Its boundaries are defined as bordering the United States to the north, Colombia to the south, the Caribbean Sea to the east, and the Pacific Ocean to the west. Central America consists of eight countries: Belize, Costa Rica, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, and Panama. Within Central America is the Mesoamerican biodiversity hotspot, which extends from northern Guatemala to central Panama. Due to the presence of several active geologic faults and the Central America Volcanic Arc, there is a high amount of seismic activity in the region, such as volcanic eruptions and earthquakes which has resulted in death, injury, and property damage. In the pre-Columbian era, Central America was inhabited by the indigenous peoples of Mesoamerica to the north and west and the Isthmo-Colombian peoples to the south and east. Following the Spanish expedition of Christopher Columbus' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Keel-billed Motmot
The keel-billed motmot (''Electron carinatum'') is a species of bird in the motmot family Momotidae. It is very closely related to the broad-billed motmot, and the two may be the same species. The two are similar sizes and shapes, and have been reported to have similar calls, but they do have different plumage.Snow, D., Kirwan, G.M. & Sharpe, C.J. (2017). Keel-billed Motmot (''Electron carinatum)''. In: del Hoyo, J., Elliott, A., Sargatal, J., Christie, D.A. & de Juana, E. (eds.). Handbook of the Birds of the World Alive. Lynx Edicions, Barcelona. (retrieved from http://www.hbw.com/node/55822 on 8 March 2017). It is found in Belize, Costa Rica, Guatemala, Honduras, Nicaragua, and Mexico. Its natural habitats are tropical moist lowland forests and tropical moist montane forests. The species is generally found below , but in Honduras it can be found up to . The keel-billed motmot is a smallish member of the family, measuring , with males weighing . The plumage is green overall, o ...

Johannes Gistel
Johannes von Nepomuk Franz Xaver Gistel ''Gistl(11 August 1809 – 9 March 1873) was a German naturalist. He worked at the Museum of Natural History in Regensburg, and wrote on a range of topics under the pseudonyms Garduus and G. Tilesius (an anagram). His contributions to entomology include descriptions of species, with many new names he proposed now mostly relegated to synonymy. Gistel's father Franz Xaver Gistl (1783–1815) worked at the a royal riding school and died in 1813. Gistel was raised by his mother, Maria Anna Gistl (née Hahn, born 1772) and his older sister Katharina Leonora (born 1808). School records indicate that his original name was Lorenz Gistl. He was educated in schools in Rempart and Schönfeld before joining the royal gymnasium in Munich in 1822. His degrees in medicine and philosophy appear to be fake. He wrote works on entomology such as ''Die jetzt lebenden Entomologen, Kerffreunde und kerfsammler Europa’s und der übrigen Continente'' (1836) and ...
