Muscovy Duck
The Muscovy duck (''Cairina moschata'') is a duck native to the Americas, from the Lower Rio Grande Valley of Texas and Mexico south to Argentina and Uruguay. The species has been Domestic Muscovy duck, domesticated, and feral Muscovy ducks can be found locally in New Zealand, Australia, the United States, and in Central and Eastern Europe. Description It is a large duck, with the males significantly larger than the females. The males are long and weigh up to ; females are long and weight, roughly half the weight of the males. The wingspan is from . The plumage is predominantly black, with large white patches on the wing; the back and wing feathers being iridescent and glossy in males, while the females are more drab. Muscovy ducks have long claws on their feet and a wide, flat tail. On the head, the male has a short crest on the nape. The bill is black with a speckling of pale pink. A blackish or dark red knob can be seen at the bill base, which is similar in colour to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Fleming (naturalist)
John Fleming FRSE FRS FSA (10 January 1785 – 18 November 1857) was a Scottish Free Church minister, naturalist, zoologist and geologist. He named and described several species of mollusc. During his life he tried to reconcile theology with science. Fleming Fjord in Greenland was named after him. Life Fleming was born on Kirkroads Farm near Bathgate in Linlithgowshire, the son of Alexander Fleming and his wife Catherine Nimmo. After studying divinity at the University of Edinburgh he graduated in 1805. He was licensed to preach by the Church of Scotland and ordained as minister of Bressay in the Shetland Islands in 1808. In 1810 he translated to the parish of Flisk in Fife and in 1832 translated to Clackmannan. In 1808, he became a member of the Wernerian Society, a learned society devoted to the study of natural history. Fleming became a member of the Royal Society of London on 25 February 1813 (he was not granted fellowship). In 1814, he was awarded an honorary doct ...

MtDNA
Mitochondrial DNA (mtDNA and mDNA) is the DNA located in the mitochondria organelles in a eukaryotic cell that converts chemical energy from food into adenosine triphosphate (ATP). Mitochondrial DNA is a small portion of the DNA contained in a eukaryotic cell; most of the DNA is in the cell nucleus, and, in plants and algae, the DNA also is found in plastids, such as chloroplasts. Mitochondrial DNA is responsible for coding of 13 essential subunits of the complex oxidative phosphorylation (OXPHOS) system which has a role in cellular energy conversion. Human mitochondrial DNA was the first significant part of the human genome to be sequenced. This sequencing revealed that human mtDNA has 16,569 base pairs and encodes 13 proteins. As in other vertebrates, the human mitochondrial genetic code differs slightly from nuclear DNA. Since animal mtDNA evolves faster than nuclear genetic markers, it represents a mainstay of phylogenetics and evolutionary biology. It also permits tra ...

Subfamily
In biological classification, a subfamily (Latin: ', plural ') is an auxiliary (intermediate) taxonomic rank, next below family but more inclusive than genus. Standard nomenclature rules end botanical subfamily names with "-oideae", and zoological subfamily names with "-inae". Detarioideae is an example of a botanical subfamily. Detarioideae is a subdivision of the family Fabaceae (legumes), containing 84 genera. Stevardiinae is an example of a zoological subfamily. Stevardiinae is a large subdivision of the family Characidae, a diverse clade In biology, a clade (), also known as a Monophyly, monophyletic group or natural group, is a group of organisms that is composed of a common ancestor and all of its descendants. Clades are the fundamental unit of cladistics, a modern approach t ... of freshwater fish.

Dabbling Duck
The Anatinae are a subfamily of the family Anatidae (swans, geese and ducks). Its surviving members are the dabbling ducks, which feed mainly at the surface rather than by diving. The other members of the Anatinae are the extinct moa-nalo, a young but highly apomorphic lineage derived from the dabbling ducks. There has been much debate about the systematical status and which ducks belong to the Anatinae. Some taxonomic authorities only include the dabbling ducks and their close relatives, the extinct moa-nalos. Alternatively, the Anatinae are considered to include most "ducks", and the dabbling ducks form a tribe Anatini within these. The classification as presented here more appropriately reflects the remaining uncertainty about the interrelationships of the major lineages of Anatidae (waterfowl). Systematics The dabbling duck group, of worldwide distribution, was delimited in a 1986 study to include eight genera and some 50–60 living species. However, Salvadori's teal ...

Perching Duck
The term perching ducks is used colloquially to mean any species of ducks distinguished by their readiness to perch high in trees. Until the late 20th century, perching ducks meant ''Cairinini'', a tribe of ducks in the duck, goose and swan family Anatidae, grouped together on the basis of their readiness to perch high in trees. It has been subsequently shown that the grouping is paraphyletic and their apparent similarity results from convergent evolution, with the different members more closely related to various other ducks than to each other. Perching duck species include: Plectropterinae * Spur-winged goose ''Plectropterus gambensis'' Tadorninae * Salvadori's teal ''Salvadorina waigiuensis'' (initially placed in Anatinae) * Blue duck ''Hymenolaimus malacorhynchos'' * Torrent duck ''Merganetta armata'' Anatinae * Brazilian teal ''Amazonetta brasiliensis'' Species that were formerly in the Cairinini tribe, and do not have an identified current subfamily include: * Co ...

Paraphyletic
Paraphyly is a taxonomic term describing a grouping that consists of the grouping's last common ancestor and some but not all of its descendant lineages. The grouping is said to be paraphyletic ''with respect to'' the excluded subgroups. In contrast, a monophyletic grouping (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 received currency during the debates of the 1960s and 1970s accompanying the rise of cladistics, having been coined by zoologist Willi Hennig to apply to well-known taxa like Reptilia (reptiles), which is paraphyletic with respect to birds. Reptilia contains the last common ancestor of reptiles and all descendants of that ancestor exc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White-winged Duck
The white-winged duck or white-winged wood duck (''Asarcornis scutulata'') is a large species of duck, formerly placed in the genus ''Cairina'' with the Muscovy duck (''Cairina moschata'') and allied with the dabbling ducks. However, mtDNA cytochrome ''b'' and NADH dehydrogenase subunit 2 sequence analysis indicate that the anatomical similarity to the Muscovy duck is deceiving and that the species is appropriately placed in a monotypic genus, as ''Asarcornis scutulata'', which is evolutionarily closer to the redhead (''Aythya americana'', one of the diving ducks). Description This is one of the largest living species of duck next only to the steamer ducks which are heavier. The Muscovy duck also attains sizes that nearly rival the white-winged duck, but may average a bit smaller in a wild state. Length is and wingspan is . Males weigh , while females weigh .

Musk
Musk is a class of aromatic substances commonly used as base notes in perfumery. They include glandular secretions from animals such as the musk deer, numerous plants emitting similar fragrances, and artificial substances with similar odors. ''Musk'' was a name originally given to a substance with a strong odor obtained from a gland of the musk deer. The substance has been used as a popular perfume fixative since ancient times and is one of the most expensive animal products in the world. The name originates from the Late Greek μόσχος 'moskhos', from Persian ''mushk'' and Sanskrit मुष्क muṣka () derived from Proto-Indo-European noun ''múh₂s'' meaning "mouse". The deer gland was thought to resemble a scrotum. The term is applied to various plants and animals of similar smell (e.g., muskox) and has come to encompass a wide variety of aromatic substances with similar odors, despite their often differing chemical structures and molecular shapes.

Systema Naturae
' (originally in Latin written ' with the Orthographic ligature, ligature æ) is one of the major works of the Sweden, Swedish botanist, zoologist and physician Carl Linnaeus (1707–1778) and introduced the Linnaean taxonomy. Although the system, now known as binomial nomenclature, was partially developed by the Bauhin brothers, Gaspard Bauhin, Gaspard and Johann Bauhin, Johann, Linnaeus was the first to use it consistently throughout his book. The first edition was published in 1735. The full title of the 10th edition (1758), which was the most important one, was ', which appeared in English in 1806 with the title: "A General System of Nature, Through the Three Grand Kingdoms of Animals, Vegetables, and Minerals, Systematically Divided Into their Several Classes, Orders, Genera, Species, and Varieties, with their Habitations, Manners, Economy, Structure and Peculiarities".

Culinary
Culinary arts are the cuisine arts of food preparation, cooking, and presentation of food, usually in the form of meals. People working in this field – especially in establishments such as restaurants – are commonly called chefs or cooks, although, at its most general, the terms culinary artist and culinarian are also used. Expert chefs are in charge of making meals that are both aesthetically beautiful and delicious. This often requires understanding of food science, nutrition, and diet. Delicatessens and relatively large institutions like hotels and hospitals rank as their principal workplaces after restaurants. History The origins of culinary arts began with primitive humans roughly 2 million years ago. Various theories exist as to how early humans used fire to cook meat. According to anthropologist Richard Wrangham, author of ''Catching Fire: How Cooking Made Us Human'', primitive humans simply tossed a raw hunk of meat into the flames and watched it sizzle. ...
