Rainbow Smelt
The rainbow smelt (''Osmerus mordax'') is a North American species of fish of the family Osmeridae. Walleye, trout, and other larger fish prey on these smelt. The rainbow smelt prefer juvenile ciscoes, zooplankton such as calanoid copepods ('' Leptodiaptomus ashlandi'', '' L. minutus'', '' L. sicilis''), and other small organisms, but are aggressive and will eat almost any fish they find. They are anadromous spring spawners and prefer clean streams with light flow and light siltation. The rainbow smelt face several barriers. They are weak swimmers and struggle to navigate fish ladders preventing them from making it past dams to the headwater streams where they spawn. The rise in erosion and dams helped to decimate the smelt population in the 1980s. There are currently plans to try to reduce damming and to help control erosion. Description The body of the rainbow smelt is slender and cylindrical. It has a silvery, pale green back and is iridescent purple, blue, and pink on the ...

Pygmy Smelt
The pygmy smelt (''Osmerus spectrum'') is a North-American freshwater fish in the family Osmeridae. It is found in a number of deep, thermally stratified lakes in eastern Canada and New England (United States). The pygmy smelt coexists with the rainbow smelt ''Osmerus mordax'', and is distinguished from it by slower growth, earlier maturation, shorter life span, later spawning time, and use of smaller food items. Genetic data suggest that the pygmy smelt occurrences in each lake have evolved independently from the rainbow smelt lineage, which calls the identity of the pygmy smelt as a species into question. Another, intermediate form of smelt has been identified in Lake Utopia, New Brunswick New Brunswick (french: Nouveau-Brunswick, , locally ) is one of the thirteen provinces and territories of Canada. It is one of the three Maritime provinces and one of the four Atlantic provinces. It is the only province with both English and ..., which is genetically distinct from lo ...

European Smelt
The smelt or European smelt (''Osmerus eperlanus'') is a species of fish in the family Osmeridae. Shape and appearance The body of the European smelt is typically 15 to 18 cm long, slender and slightly flattened on either side. Larger fish may reach 30 cm in length. Smelts have a slightly translucent body. The back and sides are grey-green to pink in colour, the flanks bright silver. The tailfin has a dark border. The smelt lives for up to six years. One characteristic is its intense smell, reminiscent of fresh cucumbers. Habitat and life The smelt is a sea fish that lives in the coastal waters of Europe from the Baltic Sea to the Bay of Biscay. A freshwater form, known in Germany as the ''Binnenstint'' ("Inland smelt"), is common in the larger lakes of Northern Europe. The smelt gather and swim about in the underflows of stronger currents in order to spawn above areas of sand. This takes place from the end of February to March, if the water temperature is above 9 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Smelt (fish)
Smelts are a family of small fish, the Osmeridae, found in the North Atlantic and North Pacific Oceans, as well as rivers, streams and lakes in Europe, North America and Northeast Asia. They are also known as freshwater smelts or typical smelts to distinguish them from the related Argentinidae (herring smelts or argentines), Bathylagidae (deep-sea smelts), and Retropinnidae (Australian and New Zealand smelts). Some smelt species are common in the North American Great Lakes, and in the lakes and seas of the northern part of Europe, where they run in large Shoaling and schooling, schools along the saltwater coastline during spring migration to their spawning streams. In some western parts of the United States, smelt populations have greatly declined in recent decades, leading to their protection under the Endangered Species Act. The Delta smelt (''Hypomesus transpacificus'') found in the Sacramento Delta of California, and the eulachon (''Thaleichthys pacificus'') found in the Nort ...

Thanetian
The Thanetian is, in the International Commission on Stratigraphy, ICS Geologic timescale, the latest age (geology), age or uppermost stage (stratigraphy), stratigraphic stage of the Paleocene epoch (geology), Epoch or series (stratigraphy), Series. It spans the time between . The Thanetian is preceded by the Selandian Age and followed by the Ypresian Age (part of the Eocene). The Thanetian is sometimes referred to as the Late Paleocene. Stratigraphic definition The Thanetian was established by Switzerland, Swiss geologist Eugène Renevier in 1873. The Thanetian is named after the Thanet Formation, the oldest Cenozoic deposit of the London Basin, which was first identified in the area of Kent (southern England) known as the Isle of Thanet. The base of the Thanetian Stage is laid at the base of magnetic chronozone C26n. The references profile (Global Boundary Stratotype Section and Point) is in the Zumaia section (43° 18'N, 2° 16'W) at the beach of Itzurun, Pais Vasco, northern ...

Taxa Named By Carl Linnaeus
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Edward Drinker Cope
Edward Drinker Cope (July 28, 1840 – April 12, 1897) was an American zoologist, paleontologist, comparative anatomist, herpetologist, and ichthyologist. Born to a wealthy Quaker family, Cope distinguished himself as a child prodigy interested in science; he published his first scientific paper at the age of 19. Though his father tried to raise Cope as a gentleman farmer, he eventually acquiesced to his son's scientific aspirations. Cope married his cousin and had one child; the family moved from Philadelphia to Haddonfield, New Jersey, although Cope would maintain a residence and museum in Philadelphia in his later years. Cope had little formal scientific training, and he eschewed a teaching position for field work. He made regular trips to the American West, prospecting in the 1870s and 1880s, often as a member of United States Geological Survey teams. A personal feud between Cope and paleontologist Othniel Charles Marsh led to a period of intense fossil-finding competition ...

Rudolf Kner
Rudolf Ignaz Kner (24 August 1810 – 27 October 1869) was an Austrian geologist, paleontologist, zoologist and ichthyologist. He also wrote some poems which were published by his brother-in-law K.A. Kaltenbrunner. Biography Kner was born in Linz where his father Johann Evangelist Georg Kner (1763-1845) was a tax officer. His mother Barbara (1770-1825), daughter of forester Johann von Adlersburg was earlier married to apothecary Felix Gulielmo until his death. Barbara had a daughter Marie Gulielmo from her earlier marriage before having Rudolf and his sister Pauline. Pauline Anna Barbara Kner (1809-1843) married the Austrian poet Karl Adam Kaltenbrunner (1804-1867) in 1834. Rudolf studied in the secondary school in Linz from 1818 and the high school from 1821. During this period he was encouraged in the natural sciences with a gift of minerals from his uncle Hallstatt Maximilian Kner (1755–1821). From 1823 he went to the Stiftsgymnasium Kremsmünster.
