Dixiphia Pipra
The white-crowned manakin (''Pseudopipra pipra'') is a small passerine bird in the manakin family Pipridae. This common and extremely widespread manakin is one of the most easily identified, even in female plumage. It is a resident breeder in the tropical New World from Costa Rica to northeastern Peru and eastern Brazil. It was traditionally placed in the genus ''Pipra'', but is now placed in its own monotypic genus ''Pseudopipra''. It is a small, compact bird about long. Males have black plumage with a white crown which can be erected as a crest, the only member of the Pipridae to possess both an all-black body and a gleaming white crown. Females and juveniles are olive-green, with a grey head and throat, and greyish-green or olive underparts. At breeding time, males are involved in a lekking behaviour. This is a fairly common species with a wide range, and the International Union for Conservation of Nature has rated its conservation status as being of "least concern". Taxonomy ...

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Albertus Seba
Albertus or Albert Seba (May 12, 1665, Etzel near Friedeburg – May 2, 1736, Amsterdam) was a Dutch pharmacist, zoologist, and collector. Seba accumulated one of the largest cabinets of curiosities in the Netherlands during his time. He sold one of his cabinets in 1717 to Peter the Great of Russia. His later collections were auctioned after his death. He published descriptions of his collections in a lavishly illustrated 4 volume . His early work on taxonomy and natural history influenced Linnaeus. Career Born in Etzel, Seba moved to Amsterdam as an apprentice and, around 1700, opened a pharmacy near the harbour. Seba asked sailors and ship surgeons to bring exotic plants and animal products he could use for preparing drugs. Seba also started to collect snakes, birds, insects, shells, and lizards in his house. From 1711, he delivered various medicines to the Russian court in Saint Petersburg and sometimes accepted fresh ginger as payment. Seba promoted his collection to R ...

Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Molecular Phylogenetic
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree.

Ludwig Reichenbach
Heinrich Gottlieb Ludwig Reichenbach (8 January 1793 – 17 March 1879) was a German botanist and ornithologist. It was he who first requested Leopold Blaschka to make a set of glass marine invertebrate models for scientific education and museum showcasing, the successful commission giving rise to the creation of the Blaschkas' Glass sea creatures and, subsequently and indirectly, the more famous Glass Flowers. Early life Born in Leipzig and the son of Johann Friedrich Jakob Reichenbach (the author in 1818 of the first Greek-German dictionary) Reichenbach studied medicine and natural science at the University of Leipzig in 1810 and, eight years later in 1818, he the now Professor became an instructor before, in 1820, he was appointed the director of the Dresden natural history museum and a professor at the Surgical-Medical Academy in Dresden, where he remained for many years.

Polyphyletic
A polyphyletic group is an assemblage of organisms or other evolving elements that is of mixed evolutionary origin. The term is often applied to groups that share similar features known as homoplasies, which are explained as a result of convergent evolution. The arrangement of the members of a polyphyletic group is called a polyphyly .. ource for pronunciation./ref> It is contrasted with monophyly and paraphyly. For example, the biological characteristic of warm-bloodedness evolved separately in the ancestors of mammals and the ancestors of birds; "warm-blooded animals" is therefore a polyphyletic grouping. Other examples of polyphyletic groups are algae, C4 photosynthetic plants, and edentates. Many taxonomists aim to avoid homoplasies in grouping taxa together, with a goal to identify and eliminate groups that are found to be polyphyletic. This is often the stimulus for major revisions of the classification schemes. Researchers concerned more with ecology than with systema ...

Syrinx (bird Anatomy)
The syrinx (from the Greek word "σύριγξ" for ''pan pipes'') is the vocal organ of birds. Located at the base of a bird's trachea, it produces sounds without the vocal folds of mammals. The sound is produced by vibrations of some or all of the ''membrana tympaniformis'' (the walls of the syrinx) and the ''pessulus'', caused by air flowing through the syrinx. This sets up a self-oscillating system that modulates the airflow creating the sound. The muscles modulate the sound shape by changing the tension of the membranes and the bronchial openings. The syrinx enables some species of birds (such as parrots, crows, and mynas) to mimic human speech. Unlike the larynx in mammals, the syrinx is located where the trachea forks into the lungs. Thus, lateralization is possible, with muscles on the left and right branch modulating vibrations independently so that some songbirds can produce more than one sound at a time. Some species of birds, such as New World vultures, lack a syrin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Richard Prum
Richard O. Prum (born 1961) is William Robertson Coe Professor of ornithology, and head curator of vertebrate zoology at the Peabody Museum of Natural History at Yale University. Life and work Prum describes himself as "an evolutionary ornithologist with broad interests in diverse topics," including phylogenetics, behavior, feathers, structural coloration, evolution and development, sexual selection, and historical biogeography. Prum grew up in rural Vermont and took his bachelor degree at Harvard in 1983, and received his PhD in 1989 from the University of Michigan. After gradually losing his hearing throughout the early 1990s due to illness, Prum moved from primarily doing field work to conducting research on plumage pigmentation, feather evolution, and Darwin's sexual selection theory. He released a book in 2017 on the role of beauty in natural selection: ''The Evolution of Beauty: How Darwin's Forgotten Theory of Mate Choice Shapes the Animal World – And Us''. Reception ...

Aristotle
Aristotle (; grc-gre, Ἀριστοτέλης ''Aristotélēs'', ; 384–322 BC) was a Greek philosopher and polymath during the Classical period in Ancient Greece. Taught by Plato, he was the founder of the Peripatetic school of philosophy within the Lyceum and the wider Aristotelian tradition. His writings cover many subjects including physics, biology, zoology, metaphysics, logic, ethics, aesthetics, poetry, theatre, music, rhetoric, psychology, linguistics, economics, politics, meteorology, geology, and government. Aristotle provided a complex synthesis of the various philosophies existing prior to him. It was above all from his teachings that the West inherited its intellectual lexicon, as well as problems and methods of inquiry. As a result, his philosophy has exerted a unique influence on almost every form of knowledge in the West and it continues to be a subject of contemporary philosophical discussion. Little is known about his life. Aristotle was born in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
