Incilius Melanochlorus
''Incilius melanochlorus'', formerly ''Bufo melanochlorus'', is a mid-sized species of toad with a crested head in the family Bufonidae. It is primarily distinguished by its very long first finger with respect to the other fingers. It is found in southern Nicaragua, in the northern Cordillera Central (central highlands) and on the Atlantic slopes of eastern Costa Rica, and in western Panama. Vernacular names Frank and Ramus (1995) give it the common name dark green toad, Panamanian herpetologists Jaramillo and Ibáñez (2009) use wet forest toad or west forest toad according to Darrel R. Frost (likely a misspelling). A local Spanish name from Costa Rica specifically for this species is '' sapo Costaricense de la selva'', but it also just known as ''sapo''. Taxonomy The first article about this species was published in 1875 by Edward Drinker Cope who wrote of the toad as a particular but unnamed variety of ''Bufo valliceps'' from eastern Costa Rica. It was described as a nov ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edward Drinker Cope
Edward Drinker Cope (July 28, 1840 – April 12, 1897) was an American zoologist, paleontologist, comparative anatomist, herpetologist, and ichthyologist. Born to a wealthy Quaker family, Cope distinguished himself as a child prodigy interested in science; he published his first scientific paper at the age of 19. Though his father tried to raise Cope as a gentleman farmer, he eventually acquiesced to his son's scientific aspirations. Cope married his cousin and had one child; the family moved from Philadelphia to Haddonfield, New Jersey, although Cope would maintain a residence and museum in Philadelphia in his later years. Cope had little formal scientific training, and he eschewed a teaching position for field work. He made regular trips to the American West, prospecting in the 1870s and 1880s, often as a member of United States Geological Survey teams. A personal feud between Cope and paleontologist Othniel Charles Marsh led to a period of intense fossil-finding competiti ...

A Greek–English Lexicon
''A Greek–English Lexicon'', often referred to as ''Liddell & Scott'' () or ''Liddell–Scott–Jones'' (''LSJ''), is a standard lexicographical work of the Ancient Greek language originally edited by Henry George Liddell, Robert Scott, Henry Stuart Jones, and Roderick McKenzie and published in 1843 by the Oxford University Press. It was most recently revised for its ninth edition of 1940. Abridged versions and a supplement exist. It was initially the basis for the 2021 '' Cambridge Greek Lexicon'', although subsequently that became a complete rewrite from scratch. Liddell and Scott's lexicon (1843 to 1940) The lexicon was begun in the 19th century, and is now in its ninth (revised) edition, published in 1940. It was based on the earlier by the German lexicographer Franz Passow (first published in 1819, fourth edition 1831), which in turn was based on Johann Gottlob Schneider's . The ''Lexicon'' has served as the basis for all later lexicographical work on the ancien ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phylogenetic
In biology, phylogenetics (; from Greek φυλή/ φῦλον [] "tribe, clan, race", and wikt:γενετικός, γενετικός [] "origin, source, birth") is the study of the evolutionary history and relationships among or within groups of organisms. These relationships are determined by Computational phylogenetics, phylogenetic inference methods that focus on observed heritable traits, such as DNA sequences, protein amino acid sequences, or morphology. The result of such an analysis is a phylogenetic tree—a diagram containing a hypothesis of relationships that reflects the evolutionary history of a group of organisms. The tips of a phylogenetic tree can be living taxa or fossils, and represent the "end" or the present time in an evolutionary lineage. A phylogenetic diagram can be rooted or unrooted. A rooted tree diagram indicates the hypothetical common ancestor of the tree. An unrooted tree diagram (a network) makes no assumption about the ancestral line, and does ...

Paraphyletic
In taxonomy, a group is paraphyletic if it consists of the group's last common ancestor and most of its descendants, excluding a few monophyletic subgroups. The group is said to be paraphyletic ''with respect to'' the excluded subgroups. In contrast, a monophyletic group (a clade) includes a common ancestor and ''all'' of its descendants. The terms are commonly used in phylogenetics (a subfield of biology) and in the tree model of historical linguistics. Paraphyletic groups are identified by a combination of synapomorphies and symplesiomorphies. If many subgroups are missing from the named group, it is said to be polyparaphyletic. The term was coined by Willi Hennig to apply to well-known taxa like Reptilia ( reptiles) which, as commonly named and traditionally defined, is paraphyletic with respect to mammals and birds. Reptilia contains the last common ancestor of reptiles and all descendants of that ancestor, including all extant reptiles as well as the extinct synaps ...

Monophyly
In cladistics for a group of organisms, monophyly is the condition of being a clade—that is, a group of taxa composed only of a common ancestor (or more precisely an ancestral population) and all of its lineal descendants. Monophyletic groups are typically characterised by shared derived characteristics ( synapomorphies), which distinguish organisms in the clade from other organisms. An equivalent term is holophyly. The word "mono-phyly" means "one-tribe" in Greek. Monophyly is contrasted with paraphyly and polyphyly as shown in the second diagram. A ''paraphyletic group'' consists of all of the descendants of a common ancestor minus one or more monophyletic groups. A '' polyphyletic group'' is characterized by convergent features or habits of scientific interest (for example, night-active primates, fruit trees, aquatic insects). The features by which a polyphyletic group is differentiated from others are not inherited from a common ancestor. These definitions have tak ...

Henry Adams
Henry Brooks Adams (February 16, 1838 – March 27, 1918) was an American historian and a member of the Adams political family, descended from two U.S. Presidents. As a young Harvard graduate, he served as secretary to his father, Charles Francis Adams, Abraham Lincoln's ambassador to the United Kingdom. The posting influenced the younger man through the experience of wartime diplomacy, and absorption in English culture, especially the works of John Stuart Mill. After the American Civil War, he became a political journalist who entertained America's foremost intellectuals at his homes in Washington and Boston. During his lifetime, he was best known for '' The History of the United States of America 1801–1817'', a nine-volume work, praised for its literary style, command of the documentary evidence, and deep (family) knowledge of the period and its major figures. His posthumously published memoir, ''The Education of Henry Adams'', won the Pulitzer Prize and went on to be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Principle Of Priority
270px, '' valid name. Priority is a fundamental principle of modern botanical nomenclature and zoological nomenclature. Essentially, it is the principle of recognising the first valid application of a name to a plant or animal. There are two aspects to this: # The first formal scientific name given to a plant or animal taxon shall be the name that is to be used, called the valid name in zoology and correct name in botany (principle of synonymy). # Once a name has been used, no subsequent publication of that name for another taxon shall be valid (zoology) or validly published (botany) (principle of homonymy). Note that nomenclature for botany and zoology is independent, and the rules of priority regarding homonyms operate within each discipline but not between them. There are formal provisions for making exceptions to the principle of priority under each of the Codes. If an archaic or obscure prior name is discovered for an established taxon, the current name can be decla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.

Incilius Fastidiosus
''Incilius fastidiosus'', or the Pico Blanco toad, is a species of toad from western Panama and southeastern Costa Rica. It inhabits premontane and lower montane rainforest. It is largely a fossorial species that breeds explosively in temporary pools after heavy rains in late April–May. Juveniles occur on rocky stream margins the year round. It is listed as a critically endangered species due to a drastic population decline, probably caused by chytridiomycosis, and to some extent, 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 ....

Darrel Frost
Darrel Richmond Frost (born 1951) is an American herpetologist and systematist. He was previously head curator of herpetology at the American Museum of Natural History, as well as president of both the Society for the Study of Amphibians and Reptiles (1998) and the American Society of Ichthyologists and Herpetologists (2006). Four taxa are named in his honor: the toad genus '' Frostius'' (which includes Frost's toad), the tree frog '' Dendropsophus frosti'', Darrel's chorus frog ''Microhyla darreli'', and Frost's arboreal alligator lizard '' Abronia frosti''. Life Frost became interested in animals after witnessing his father kill a rattlesnake at the age of four. He earned a B.S. in Biology from the University of Arizona in 1973, an M.S. in Zoology from Louisiana State University in 1978, and a Ph.D. in Ecology and Systematics from the University of Kansas in 1988. He became an adjunct professor at Columbia University in 2000. In 1990, Frost was appointed Assistant Curator ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Incilius Aucoinae
''Incilius aucoinae'' is a species of toads in the family Bufonidae. It is found in south-western Costa Rica and adjacent western Panama. Before its description in 2004, it was confused with '' Incilius melanochlorus''. Etymology The specific name ''aucoinae'' honors Lisa Aucoin (1971–2001), an American herpetologist Herpetology (from Greek ἑρπετόν ''herpetón'', meaning "reptile" or "creeping animal") is the branch of zoology concerned with the study of amphibians (including frogs, toads, salamanders, newts, and caecilians ( gymnophiona)) and rep ... who died in a car accident shortly after returning from a trip to Costa Rica. Habitat and conservation It is a very abundant species living in forested habitats, from tree plantations to primary forests.

Taxon
In biology, a taxon ( back-formation from '' 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 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 system in '' Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
