Wallace's Fruit Dove
Wallace's fruit dove (''Ptilinopus wallacii'') is a species of bird in the pigeon family Columbidae. The name commemorates the British naturalist Alfred Russel Wallace. It is a rather large, long-tailed fruit dove with a length of and has been described as "one of the most beautiful" fruit doves. The forehead and are dull crimson, the lower face and throat are white, and the rest of the head, breast, neck, and upper back are pale bluish-grey. The wings and lower back are green and the belly is orange, separated from the chest by a white band. Both sexes look similar, but females have less extensive red on the head and a greenish tinge to their grey parts. Endemic to Indonesia, Wallace's fruit dove is found in lowland riverine and coastal forests in the Lesser Sunda Islands, the Moluccas, the Aru Islands, and occasionally in southwestern New Guinea. Its diet consists of small fruits and berries. Nests are made out of twigs in branches and the only observed nest was made in Novemb ...

George Robert Gray
George Robert Gray FRS (8 July 1808 – 6 May 1872) was an English zoologist and author, and head of the ornithological section of the British Museum, now the Natural History Museum, in London for forty-one years. He was the younger brother of the zoologist John Edward Gray and the son of the botanist Samuel Frederick Gray. George Gray's most important publication was his ''Genera of Birds'' (1844–49), illustrated by David William Mitchell and Joseph Wolf, which included 46,000 references. Biography He was born in Little Chelsea, London, to Samuel Frederick Gray, naturalist and pharmacologist, and Elizabeth (née Forfeit), his wife. He was educated at Merchant Taylor's School. Gray started at the British Museum as Assistant Keeper of the Zoology Branch in 1831. He began by cataloguing insects, and published an ''Entomology of Australia'' (1833) and contributed the entomogical section to an English edition of Georges Cuvier's ''Animal Kingdom''. Gray described many spec ... [...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] |
Sister Group
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 ...

Ornate Fruit Dove
The ornate fruit dove (''Ptilinopus ornatus'') is a species of bird in the family Columbidae. It is found in New Guinea. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical moist montane forest. Taxonomy and systematics The ornate fruit dove was originally described as ''Ptilopus ornatus'' (an incorrect spelling of '' Ptilinopus'') by Hermann Schlegel in 1871 on the basis of specimens from New Guinea. The species' generic name comes from the Ancient Greek ''ptilon'' (feather) and ''pous'' (foot), while the specific name ''ornatus'' is from the Latin word ''ornatus'', meaning ornate or decorated. Ornate fruit dove is the official common name designated by the International Ornithologists' Union (IOU). The ornate fruit dove is one of over 50 species of pigeon in the fruit dove genus ''Ptilinopus'', which is found throughout Southeast Asia and Oceania.

Orange-fronted Fruit Dove
The orange-fronted fruit dove (''Ptilinopus aurantiifrons'') is a species of bird in the family Columbidae. It is found in New Guinea. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical mangrove forest Mangrove forests, also called mangrove swamps, mangrove thickets or mangals, are productive wetlands that occur in coastal intertidal zones. Mangrove forests grow mainly at tropical and subtropical latitudes because mangroves cannot withstand fr ....

Clade
A clade (), also known as a monophyletic group or natural group, is a group of organisms that are monophyletic – that is, composed of a common ancestor and all its lineal descendants – on a phylogenetic tree. Rather than the English term, the equivalent Latin term ''cladus'' (plural ''cladi'') is often used in taxonomical literature. The common ancestor may be an individual, a population, or a species (extinct or extant). Clades are nested, one in another, as each branch in turn splits into smaller branches. These splits reflect evolutionary history as populations diverged and evolved independently. Clades are termed monophyletic (Greek: "one clan") groups. Over the last few decades, the cladistic approach has revolutionized biological classification and revealed surprising evolutionary relationships among organisms. Increasingly, taxonomists try to avoid naming taxa that are not clades; that is, taxa that are not monophyletic. Some of the relationships between organisms ...

Nuclear DNA
Nuclear DNA (nDNA), or nuclear deoxyribonucleic acid, is the DNA contained within each cell nucleus of a eukaryotic organism. It encodes for the majority of the genome in eukaryotes, with mitochondrial DNA and plastid DNA coding for the rest. It adheres to Mendelian inheritance, with information coming from two parents, one male and one female—rather than matrilineally (through the mother) as in mitochondrial DNA. Structure Nuclear DNA is a nucleic acid, a polymeric biomolecule or biopolymer, found in the nucleus of eukaryotic cells. Its structure is a double helix, with two strands wound around each other, a structure first described by Francis Crick and James D. Watson (1953) using data collected by Rosalind Franklin. Each strand is a long polymer chain of repeating nucleotides. Each nucleotide is composed of a five-carbon sugar, a phosphate group, and an organic base. Nucleotides are distinguished by their bases: purines, large bases that include adenine and guanine; and pyr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mitochondrial DNA
Mitochondrial DNA (mtDNA or mDNA) is the DNA located in mitochondria, cellular organelles within eukaryotic cells that convert chemical energy from food into a form that cells can use, such as adenosine triphosphate (ATP). Mitochondrial DNA is only a small portion of the DNA in a eukaryotic cell; most of the DNA can be found in the cell nucleus and, in plants and algae, also in plastids such as chloroplasts. Human mitochondrial DNA was the first significant part of the human genome to be sequenced. This sequencing revealed that the human mtDNA includes 16,569 base pairs and encodes 13 proteins. Since animal mtDNA evolves faster than nuclear genetic markers, it represents a mainstay of phylogenetics and evolutionary biology. It also permits an examination of the relatedness of populations, and so has become important in anthropology and biogeography. Origin Nuclear and mitochondrial DNA are thought to be of separate evolutionary origin, with the mtDNA being derived ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ptilinopus
The fruit doves, also known as fruit pigeons, are a genus (''Ptilinopus'') of birds in the pigeon and dove family (Columbidae). These colourful, frugivorous doves are found in forests and woodlands in Southeast Asia and Oceania. It is a large genus with over 50 species, some threatened or already extinct. Taxonomy The genus ''Ptilinopus'' was introduced in 1825 by the English naturalist William John Swainson with the rose-crowned fruit dove (''Ptilinopus regina'') as the type species. The genus name combines the Ancient Greek meaning "feather" with meaning "foot". The many species of this genus can be further grouped by geography and by certain shared characteristics. The fruit doves of the Sunda Islands and northern Australia, such as the pink-headed fruit dove and banded fruit dove, have comparatively longer tails than other species, and are notable for their solid colouration on the head, neck and breast, with a black band across the belly. Another grouping can be made of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Princeton University Press
Princeton University Press is an independent publisher with close connections to Princeton University. Its mission is to disseminate scholarship within academia and society at large. The press was founded by Whitney Darrow, with the financial support of Charles Scribner, as a printing press to serve the Princeton community in 1905. Its distinctive building was constructed in 1911 on William Street in Princeton. Its first book was a new 1912 edition of John Witherspoon's ''Lectures on Moral Philosophy.'' History Princeton University Press was founded in 1905 by a recent Princeton graduate, Whitney Darrow, with financial support from another Princetonian, Charles Scribner II. Darrow and Scribner purchased the equipment and assumed the operations of two already existing local publishers, that of the ''Princeton Alumni Weekly'' and the Princeton Press. The new press printed both local newspapers, university documents, ''The Daily Princetonian'', and later added book publishing to it ...
