Blue Noddy
The blue noddy or ''hinaokū'' or ''manuohina'' (''Anous cerulea'') is a seabird in the family Laridae. It is also known as the blue-grey noddy. It is found in American Samoa, the Cook Islands, Fiji, French Polynesia, Kiribati, Marshall Islands, New Caledonia, Samoa, Tonga (Niua), Tuvalu and Hawaii. It has occurred as a vagrant in Australia and Japan. Its natural habitat is open, shallow seas in tropical and subtropical regions. Taxonomy The first formal description of the blue noddy was by Frederick Debell Bennett in 1840 under the binomial name ''Sterna cerulea''. The specific name ''cerulea'' is Latin for "dark blue". The blue noddy was formerly placed in the genus ''Procelsterna''. A molecular phylogenetic study published in 2016 found that the five noddies formed a single clade with the blue noddy and the grey noddy in ''Procelsterna'' nested between the species in the genus ''Anous''. The authors proposed that the noddies should be merged into a single genus ''An ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frederick Debell Bennett
Frederick Debell Bennett (1806 - 1859) was an English ship surgeon and biologist. Born to a family of means in Devon, England. in 1806, he obtained his Licentiate of the Society of Apothecaries (L.S.A.) in 182, and his membership of the Royal College of Surgeons in 1829. Bennett first served as Assistant Surgeon on the hospital ship Grampus, which was moored on the Thames. Then in 1833, he joined the London whaleship Tuscan. From 1833-1836 he sailed round the globe on board the 'Tuscan'. The task of this journey was to study whales, lands and nature. He described several species, for example Whalesucker (''Remora australis''), blue noddy and ''Cheilopogon nigricans''. He was also a member of the Royal Geographical Society. After his return he practiced medicine in Southwark where he died in 1859 at the age of fifty-three.Druett, Joan, Rough Medicine: Surgeons at Sea in the Age of Sail.

Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scientific Name
In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, name or a scientific name; more informally it is also historically called a Latin name. The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Homo sapiens''. ''Tyrannosaurus rex'' is likely the most widely known binomial. The ''formal'' introduction of this system of naming species is credit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Research Ship
A research vessel (RV or R/V) is a ship or boat designed, modified, or equipped to carry out research at sea. Research vessels carry out a number of roles. Some of these roles can be combined into a single vessel but others require a dedicated vessel. Due to the demanding nature of the work, research vessels may be constructed around an icebreaker hull, allowing them to operate in polar waters. History The research ship had origins in the early voyages of exploration. By the time of James Cook's ''Endeavour'', the essentials of what today we would call a research ship are clearly apparent. In 1766, the Royal Society hired Cook to travel to the Pacific Ocean to observe and record the transit of Venus across the Sun. The ''Endeavour'' was a sturdy vessel, well designed and equipped for the ordeals she would face, and fitted out with facilities for her "research personnel", Joseph Banks. As is common with contemporary research vessels, ''Endeavour'' also carried out more than ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Fish Commission
The United States Fish Commission, formally known as the United States Commission of Fish and Fisheries, was an agency of the United States government created in 1871 to investigate, promote, and preserve the fisheries of the United States. In 1903, it was reorganized as the United States Bureau of Fisheries, sometimes referred to as the United States Fisheries Service, which operated until 1940. In 1940, the Bureau of Fisheries was abolished when its personnel and facilities became part of the newly created Fish and Wildlife Service, under the United States Department of the Interior. Organizational history U.S. Fish Commission (1871–1903) By the 1860s, increasing human pressure on the fish and game resources of the United States had become apparent to the United States Government, and fisheries became the first aspect of the problem to receive U.S. Government attention when Robert Barnwell Roosevelt, a Democratic congressmen from New Yorks 4th Congressional District, ori ...

Northwestern Hawaiian Islands
The Northwestern Hawaiian Islands or Leeward Hawaiian Islands are a series of islands and atolls in the Hawaiian island chain located northwest (in some cases, far to the northwest) of the islands of Kauai and Niihau. Politically, they are all part of Honolulu County in the U.S. state of Hawaii, except Midway Atoll, which is a territory distinct from the State of Hawaii, and grouped as one of the United States Minor Outlying Islands. The United States Census Bureau defines this area, except Midway, as Census Tract 114.98 of Honolulu County. Its total land area is . All the islands except Nihoa are north of the Tropic of Cancer, making them the only islands in Hawaii that lie outside the tropics. The Northwestern or Leeward Hawaiian Islands include: *Nihoa (Moku Manu) at * Necker (Mokumanamana) at *French Frigate Shoals (Kānemilohai) at *Gardner Pinnacles (Pūhāhonu) at *Maro Reef (Nalukākala) at *Laysan (Kauō) at * Lisianski (Papaāpoho) at *Pearl and Hermes Atoll (Hol ...

Nihoa
Nihoa (; haw, Nīhoa ), also known as Bird Island or Moku Manu, is the tallest of ten islands and atolls in the uninhabited Northwestern Hawaiian Islands (NWHI). The island is located at the southern end of the NWHI chain, southeast of Necker Island. Nihoa is the closest NWHI in proximity to the eight main windward Hawaiian Islands at approximately northwest of the island of Kauai. The island has two peaks, Miller's Peak in the west, and Tanager Peak in the east. Nihoa's area is about and is surrounded by a coral reef. Its jagged outline gives the island its name, , which is Hawaiian for "tooth".. Captain William Douglas, the second Western explorer to find Nihoa, describes the island as "earingthe form of a saddle, high at each end, and low in the middle. To the south, it is covered with verdure; but on the north, west, and east sides it is a barren rock, perpendicularly steep..." The island is home to 25 species of plants and several animals, making it the m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
French Frigate Shoals
The French Frigate Shoals ( Hawaiian: Kānemilohai) is the largest atoll in the Northwestern Hawaiian Islands. Its name commemorates French explorer Jean-François de La Pérouse, who nearly lost two frigates when attempting to navigate the shoals. It consists of a crescent-shaped reef, twelve sandbars, and the La Perouse Pinnacle, the only remnant of its volcanic origins. The total land area of the islets is . Total coral reef area of the shoals is over . Tern Island, with an area of , has a landing strip and permanent habitations for a small number of people. It is maintained as a field station in the Hawaiian Islands National Wildlife Refuge by the United States Fish and Wildlife Service. The French Frigate Shoals are about northwest of Honolulu. In the 20th century, the shoals were used by the Imperial Japanese Navy as part of an operation to attack Hawaii; afterwards, a small United States Navy base was established there to prevent it from being used again.

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 ...

Grey Noddy
The grey noddy or grey ternlet (''Anous albivitta'') is a seabird belonging to the Family (biology), family Laridae. It was once regarded as a pale morph (zoology), morph of the blue noddy (''Anous cerulea'') but is now usually considered to be a separate species. Taxonomy The first species description, formal description of the grey noddy was by the French ornithologist Charles Lucien Bonaparte in 1856 under the binomial name ''Procelsterna albivitta''. The specific name ''albivitta'' is from the Latin ''abus'' for "white" and ''vitta'' for "band" or "head-band". The grey noddy was formerly placed in the genus ''Procelsterna''. A molecular phylogenetic study published in 2016 found that the five noddies formed a single clade with the grey noddy and blue noddy in ''Procelsterna'' nested within the species in the genus ''Anous''. The authors proposed that the noddies should be merged into a single genus ''Anous'' and that ''Procelsterna'' should be considered as a Synonym (taxo ...

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 ...
