Southern Pochard
The southern pochard (''Netta erythrophthalma'') is a species of duck, and a member of the genus ''Netta''. There are two subspecies, the South American (southern) pochard ''N. e. erythrophthalma'' (Wied-Neuwied, 1833) and the African (southern) pochard ''N. e. brunnea'' ( Eyton, 1838). The South American pochard has a fragmented range and is found from Colombia, Venezuela, Brazil, Ecuador, Peru, Bolivia and Argentina to Chile. Here it occurs in a wide variety of shallow fresh waters with submerged vegetation, from the lowlands up to 3,700 metres. The African pochard occurs from the Cape to the Ethiopian highlands on water bodies with or without emergent vegetation. They are suspected to have been strong migrants in the past but the construction of numerous farm dams seems to allow them a more sedentary lifestyle. They reach highest concentrations in Africa's central plateaus and in the south-western winter rainfall region. Taxonomy Two syntype specimens of ''Nyroca brunnea'' Ey ...

Prince Maximilian Of Wied-Neuwied
Prince Alexander Philipp Maximilian zu Wied-Neuwied (23 September 1782 – 3 February 1867) was a German explorer, ethnologist and naturalist. He led a pioneering expedition to southeast Brazil between 1815–1817, from which the album ''Reise nach Brasilien,'' which first revealed to Europe real images of Brazilian Indians, was the ultimate result. It was translated into several languages and recognized as one of the greatest contributions to the knowledge of Brazil at the beginning of the nineteenth century. In 1832 he embarked on another expedition, this time to United States, together with the Swiss painter Karl Bodmer. Prince Maximilian collected many examples of ethnography, and many specimens of flora and fauna of the area, still preserved in museum collections, notably in the Lindenmuseum, Stuttgart. The genus '' Neuwiedia'' Blume (Orchidaceae) was named for him. Also, Prince Maximilian is honored in the scientific names of eight species of reptiles: '' Hydromedusa max ...

Thomas Campbell Eyton
Thomas Campbell Eyton JP, DL (10 September 1809 – 25 October 1880) was an English naturalist whose fields were cattle, fishes and birds. He was a friend and correspondent of Charles Darwin though he opposed his theories. Eyton was born at Eyton Hall, near Wellington, Shropshire. He studied at St John's College, Cambridge, where he was a contemporary and friend of Charles Darwin. After succeeding to the estate in 1855 Eyton built a large natural history museum at Eyton Hall that included a range of bird skins and skeletons, described as "one of the finest in Europe". Besides Darwin, Eyton enjoyed a correspondence with other naturalists including Louis Agassiz, Asa Gray and Alfred Russel Wallace. Eyton published ''History of the Rarer British Birds'' (1836), ''A Monograph on the Anatidae, Or Duck Tribe'' (1838), ''A History of Oyster and Oyster Fisheries'' (1858) and ''Osteologia Avium'' (1871–78). He established in about 1842 the ''Herd Book of Hereford Cattle'', which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Duck
Duck is the common name for numerous species of waterfowl in the family Anatidae. Ducks are generally smaller and shorter-necked than swans and geese, which are members of the same family. Divided among several subfamilies, they are a form taxon; they do not represent a monophyletic group (the group of all descendants of a single common ancestral species), since swans and geese are not considered ducks. Ducks are mostly aquatic birds, and may be found in both fresh water and sea water. Ducks are sometimes confused with several types of unrelated water birds with similar forms, such as loons or divers, grebes, gallinules and coots. Etymology The word ''duck'' comes from Old English 'diver', a derivative of the verb 'to duck, bend down low as if to get under something, or dive', because of the way many species in the dabbling duck group feed by upending; compare with Dutch and German 'to dive'. This word replaced Old English / 'duck', possibly to avoid confusion with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Netta
''Netta'' is a genus of diving ducks. The name is derived from Greek ''Netta'' "duck". Unlike other diving ducks, the ''Netta'' species are reluctant to dive, and feed more like dabbling ducks. These are gregarious ducks, mainly found on fresh water. They are strong fliers; their broad, blunt-tipped wings require faster wing-beats than those of many ducks and they take off with some difficulty. They do not walk as well on land as the dabbling ducks because their legs tend to be placed further back on their bodies to help propel them when underwater. The probably extinct pink-headed duck, previously listed as ''Rhodonessa caryophyllacea'', has recently been shown by phylogenetic analysis to be closely related to the red-crested pochard The red-crested pochard (''Netta rufina'') is a large diving duck. The scientific name is derived from Greek language, Greek ''Netta'' "duck", and Latin ''rufina'', "golden-red" (from ''rufus'', "ruddy"). Its breeding habitat is lowland marshe ...

Type (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almost al ...

National Museums Liverpool
National Museums Liverpool, formerly National Museums and Galleries on Merseyside, comprises several museums and art galleries in and around Liverpool, England. All the museums and galleries in the group have free admission. The museum is a non-departmental public body sponsored by the Department for Culture, Media and Sport and an exempt charity under English law. In the 1980s, local politics in Liverpool was under the control of the Militant group of the Labour Party. In 1986, Liverpool's Militant councillors discussed closing down the city's museums and selling off their contents, in particular their art collections. To prevent this from happening the Conservative government nationalised all of Liverpool's museums under the ''Merseyside Museums and Galleries Order 1986'' which created a new national trustee body ''National Museums and Galleries on Merseyside''.Suzanne MacLeod, ''Museum Architecture: A New Biography'', p31.

World Museum
World Museum is a large museum in Liverpool, England which has extensive collections covering archaeology, ethnology and the natural and physical sciences. Special attractions include the Natural History Centre and a planetarium. Entry to the museum is free. The museum is part of National Museums Liverpool. History The museum was originally started as the Derby Museum as it comprised the 13th Earl of Derby's natural history collection. It opened in 1851, sharing two rooms on Duke Street with a library. However, the museum proved extremely popular and a new, purpose-built building was required. Land for the new building, on a street then known as Shaw's Brow (now William Brown Street), opposite St George's Hall, was donated by local MP and Merchant William Brown, as was much of the funding for the building which would be known as the William Brown Library and Museum. Around 400,000 people attended the opening of the new building in 1860. Reports detailing the museum's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aquatic Plant
Aquatic plants are plants that have adapted to living in aquatic environments (saltwater or freshwater). They are also referred to as hydrophytes or macrophytes to distinguish them from algae and other microphytes. A macrophyte is a plant that grows in or near water and is either emergent, submergent, or floating. In lakes and rivers macrophytes provide cover for fish, substrate for aquatic invertebrates, produce oxygen, and act as food for some fish and wildlife. Macrophytes are primary producers and are the basis of the food web for many organisms. They have a significant effect on soil chemistry and light levels as they slow down the flow of water and capture pollutants and trap sediments. Excess sediment will settle into the benthos aided by the reduction of flow rates caused by the presence of plant stems, leaves and roots. Some plants have the capability of absorbing pollutants into their tissue. Seaweeds are multicellular marine algae and, although their ecologi ...

Pupae
A pupa ( la, pupa, "doll"; plural: ''pupae'') is the life stage of some insects undergoing transformation between immature and mature stages. Insects that go through a pupal stage are holometabolous: they go through four distinct stages in their life cycle, the stages thereof being egg, larva, pupa, and imago. The processes of entering and completing the pupal stage are controlled by the insect's hormones, especially juvenile hormone, prothoracicotropic hormone, and ecdysone. The act of becoming a pupa is called pupation, and the act of emerging from the pupal case is called eclosion or emergence. The pupae of different groups of insects have different names such as ''chrysalis'' for the pupae of butterflies and ''tumbler'' for those of the mosquito family. Pupae may further be enclosed in other structures such as cocoons, nests, or shells. Position in life cycle The pupal stage follows the larval stage and precedes adulthood (''imago'') in insects with complete metamorphosi ...
