Wilhelm Heinrich Kramer
Wilhem Heinrich Kramer (1724 in Dresden – 13 October 1765) was a German physician and naturalist. Kramer studied in Vienna (Austria) then practiced medicine in Bruck, close to the capital, for at least fourteen years. He published in 1756 a work entitled ''Elenchus Vegetabilium and Animalium per Austriam inferiorem Observatorum'', a flora and fauna of Lower Austria noted especially because it was one of the first works to adopt the binomial nomenclature of Carl von Linné (1707–1778). In this book, Kramer created the name ''pratincola'' for the collared pratincole which was adapted in English in the following work of Thomas Pennant (1726–1798) in 1773. It is probably for him that Giovanni Antonio Scopoli (1723–1788) dedicated ''Psittacus krameri'' (today ''Psittacula krameri'') in 1769. He is also known as an entomologist Entomology () is the scientific study of insects, a branch of zoology. In the past the term "insect" was less specific, and historically the definit ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Umbridae
Umbridae is a family of fish in the order Esociformes, which contains pike, pickerel, and mudminnows. The single living genus, ''Umbra'', occupies weed-choked freshwater habitats in eastern North America and eastern Europe. While the family traditionally contained the genera ''Umbra'', '' Novumbra'', and ''Dallia'', recent genetic and paleontological research have recovered this grouping as paraphyletic, with ''Novumbra'' and ''Dallia'' being moved to the family Esocidae. Distribution Umbridae contains three extant species, all within the genus ''Umbra'': ''Umbra pygmaea'', ''Umbra limi'', and ''Umbra krameri''. ''U. pygmaea'' can be found across the eastern United States and southeastern Canada. ''U. limi'' ranges throughout the Great Lakes region and Mississippi River basin of North America. ''U. krameri'' can be found in the Danube and Dniester River basins of Europe. ''Umbra ''spp. are most commonly found in the Atlantic coast regions of North America, along the marshy, l ...

Europe
Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a Continent#Subcontinents, subcontinent of Eurasia and it is located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. Comprising the westernmost peninsulas of Eurasia, it shares the continental landmass of Afro-Eurasia with both Africa and Asia. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south and Asia to the east. Europe is commonly considered to be Boundaries between the continents of Earth#Asia and Europe, separated from Asia by the drainage divide, watershed of the Ural Mountains, the Ural (river), Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea and the waterways of the Turkish Straits.

North America
North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Plate, North American Tectonic Plate, Greenland is included as a part of North America geographically. North America covers an area of about , about 16.5% of Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the list of continents and continental subregions by population, fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 579 million people in List of sovereign states and dependent territories in North America, 23 independent states, or about 7.5% of the world's population.

Johann Julius Walbaum
Johann Julius Walbaum (30 June 1724 – 21 August 1799) was a German physician, naturalist and fauna taxonomist. Works As an ichthyologist, he was the first to describe many previously unknown fish species from remote parts of the globe, such as the Great Barracuda (''Sphyraena barracuda''), the Chum salmon (''Oncorhynchus keta'') from the Kamchatka River in Siberia, and the curimatá-pacú (''Prochilodus marggravii'') from the São Francisco River in Brazil. He was also the first to observe gloves as a preventative against infection in medical surgery. In 1758, the gloves he observed were made from the cecum of the sheep, rather than rubber, which had not yet been discovered. Legacy The Natural History Museum in Lübeck, opened in 1893, was based on Walbaum's extensive scientific collection, which was lost during the Second World War World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945.

Umbra Limi
The central mudminnow (''Umbra limi'') is a small fish in the family Umbridae of the order Esociformes. It is found in central and eastern North America in productive waters. It is fairly tolerant of low oxygen concentration In chemistry, concentration is the abundance of a constituent divided by the total volume of a mixture. Several types of mathematical description can be distinguished: '' mass concentration'', ''molar concentration'', '' number concentration'', ...s and, as a result, it is sometimes the only, or one of a very few, fish species present in waters susceptible to winter or summer kill. Description The central mudminnow lives in slow-moving water around ponds, lakes, and streams in central North America, and ranges in length from 51–102 mm. It burrows tail-first in mud and can tolerate low oxygen levels, allowing it to live in waterways unavailable to other fishes. Its coloration matches this habitat, being brownish above with mottled sides and a pal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

James Ellsworth De Kay
James Ellsworth De Kay (alternatively spelled DeKay or Dekay) (October 12, 1792 – November 21, 1851) was an American zoologist. Biography James De Kay was born in Lisbon, Portugal, in 1792. When he was two years old, his family moved to New York; both his parents died while he was still quite young. He attended Yale from 1807 to 1812, but was expelled before completing his degree when he threatened a college tutor with a club. Later, he studied medicine at the University of Edinburgh, receiving his MD in 1819. After his return to the United States, he married Janet Eckford, a daughter of Henry Eckford, a ship builder. He then traveled with his father-in-law to Turkey as a ship's physician, and published a book, ''Sketches of Turkey in 1831 and 1832,'' about these travels. Although well received as an entertaining travelogue, his book has been criticized as being very anti-Hellenic as well as sometimes naive about Turkish customs. He was entrusted by Eckford with negotiations ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
