Pelican Lake (Wisconsin)
Pelican Lake is a lake located in Oneida County in Wisconsin. It has a maximum depth of . Visitors have access to the lake from five public boat landings. A dam is located on the lake's primary outlet, which feeds into the Pelican River. Pelican Lake serves as one of 21 reservoirs used to regulate and maintain optimal water flow on the Wisconsin and Tomahawk rivers, the process of which is facilitated in part by the Wisconsin Valley Improvement Company. Fish inhabiting the lake include muskie, panfish, largemouth bass, smallmouth bass, northern pike and walleye. The lake's water clarity has historically been low, and its bottom composition is 40% sand, 20% gravel, 10% rock, 30% muck. The lake is eutrophic. Several invasive species are or have been found in the lake, including banded mystery snail, Chinese mystery snail, curly-leaf pondweed, Eurasian water-milfoil, purple loosestrife, and rusty crayfish. Pelican Lake was named for the American white pelicans seen there. I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Viviparus Georgianus
''Viviparus georgianus'', common name the banded mystery snail, is a species of large freshwater snail with gills and an operculum, an aquatic gastropod mollusk in the family Viviparidae, the river snails. This snail is native to the southeastern United States. The specific epithet ''georgianus'' is a reference to the southern State of Georgia, where the type locality is situated. Original description ''Viviparus georgianus'' was originally discovered and described (under the name ''Paludina georgiana'') by Isaac Lea in 1834. Lea's original text (the type description) reads as follows: Shell description Ecology Habitat This snail is found in lakes and slow-moving rivers with mud bottoms. The species thrives in eutrophic lentic environments such as lakes, ponds and some low-flow streams.Lee, L. E. J., J. Stassen, A. McDonald, C. Culshaw, A. D. Venosa and K. Lee. 2002. Bioremediation Journal 6(4):373-386. It is usually absent from larger, faster flowing rivers; ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ojibwe Language
Ojibwe , also known as Ojibwa , Ojibway, Otchipwe,R. R. Bishop Baraga, 1878''A Theoretical and Practical Grammar of the Otchipwe Language''/ref> Ojibwemowin, or Anishinaabemowin, is an indigenous language of North America of the Algonquian language family.Goddard, Ives, 1979.Bloomfield, Leonard, 1958. The language is characterized by a series of dialects that have local names and frequently local writing systems. There is no single dialect that is considered the most prestigious or most prominent, and no standard writing system that covers all dialects. Dialects of Ojibwemowin are spoken in Canada, from southwestern Quebec, through Ontario, Manitoba and parts of Saskatchewan, with outlying communities in Alberta;Nichols, John, 1980, pp. 1–2. and in the United States, from Michigan to Wisconsin and Minnesota, with a number of communities in North Dakota and Montana, as well as groups that removed to Kansas and Oklahoma during the Indian Removal period.

American White Pelican
The American white pelican (''Pelecanus erythrorhynchos'') is a large aquatic soaring bird from the order Pelecaniformes. It breeds in interior North America, moving south and to the coasts, as far as Central America and South America, in winter. Taxonomy The American white pelican was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's ''Systema Naturae''. He placed it with the other pelicans in the genus '' Pelecanus'' and coined the binomial name ''Pelecanus erythrorhynchos''. Gmelin based his description on the "rough-billed pelican" that had been described in 1785 by the English ornithologist John Latham. Latham had access to three specimens that had been brought to London from New York and the Hudson Bay area of North America. The scientific name means "red-billed pelican", from the Latin term for a pelican, ''Pelecanus'', and ''erythrorhynchos'', derived from the Ancient Greek words ( ἐρ ...

Rusty Crayfish
The rusty crayfish (''Faxonius rusticus'') is a large, aggressive species of freshwater crayfish which is native to the United States, in the Ohio River Basin in parts of Ohio, Kentucky, and Indiana. Its range is rapidly expanding across much of eastern North America, displacing native crayfishes in the process. The rusty crayfish was first captured in Illinois in 1973, and has been collected at over 20 locations in the northern portion of the state. In 2005, ''F. rusticus'' was found for the first time west of the Continental Divide, in the John Day River, Oregon, which runs into the Columbia River. Description Adult rusty crayfish can reach 10 centimeters (4 inches) in length, although they reach maturity at about 4.4 cm (1.7 in),Pappas, Janice''Orconectes rusticus'' Animal Diversity Web. and can range in color from greenish grey, to reddish brown, They can be easily recognized by two "rusty", reddish colored spots on the sides of their back and their large front claw ...

Purple Loosestrife
''Lythrum salicaria'' or purple loosestrifeFlora of NW Europe''Lythrum salicaria'' is a flowering plant belonging to the family Lythraceae. It should not be confused with other plants sharing the name loosestrife that are members of the family Primulaceae. Other names include spiked loosestrife and purple Lythrum. This herbaceous perennial is native to Europe and Asia, and possibly Australia. Etymology and other names The generic name ''Lythrum'' is derived from the Greek ‘lythron’, meaning blood, in reference to the flower colour in some species.Gledhill D. 1985. ''The Names of Plants''. Cambridge University Press However, Pliny (A.D. 23-79) stated that ''Lythrum'' is named for Lysimachus, an army general and friend of Alexander the Great. ‘’Lysimachus’’ is derived from the Greek ‘’lysis’’, meaning ‘’loosing’’ and ‘’mache’’, meaning strife.

Myriophyllum Spicatum
''Myriophyllum spicatum'' (Eurasian watermilfoil or spiked water-milfoil) is native to Europe, Asia, and north Africa, but has a wide geographic and climatic distribution among some 57 countries, extending from northern Canada to South Africa. It is a submerged aquatic plant, grows in still or slow-moving water, and is considered to be a highly invasive species. Description Eurasian watermilfoil has slender stems up to long. The submerged leaves (usually between 15–35 mm long) are borne in pinnate whorls of four, with numerous thread-like leaflets roughly 4–13 mm long. Plants are monoecious with flowers produced in the leaf axils (male above, female below) on a spike 5–15 cm long held vertically above the water surface, each flower is inconspicuous, orange-red, 4–6 mm long. Eurasian water milfoil has 12- 21 pairs of leaflets while northern watermilfoil ''M. sibiricum'' only has 5–9 pairs. The two can hybridize and the resulting hybrid plants can ...

Potamogeton Crispus
''Potamogeton crispus'', the crisp-leaved pondweed, curly pondweed, curly-leaf pondweed or curled pondweed, is a species of aquatic plant (hydrophyte) native to Eurasia but an introduced species and often a noxious weed in North America. Description Curly-leaf pondweed is a rhizome, rhizomatous perennial herb producing a flattened, branching stem up to a meter long. The submerged leaves are alternately arranged. The leaves are sessile, linear or oblong in shape, long and wide. The leaves may be bright green, olive green or (especially later in the season) fibrous and brownish and have noticeably serrated margins, a feature that distinguishes them from other pondweeds. The leaves usually have wavy edges but this is not always apparent, especially on new growth. Turion (botany), Turions occur in leaf axils and at stem tips. The inflorescence is a short spike of flowers emerging above the water surface. It flowers from May until October. The turions of the plant develop along w ...

Chinese Mystery Snail
The Chinese mystery snail, black snail, or trapdoor snail (''Cipangopaludina chinensis''), is a large freshwater snail with gills and an operculum, an aquatic gastropod mollusk in the family Viviparidae. The name "trapdoor snail" refers the operculum, an oval corneous plate that most snails in this clade possess. When the soft parts of the snail are fully retracted, the operculum seals the aperture of the shell, providing some protection against drying out and predation. Taxonomy Taxonomy of the introduced populations of Oriental mystery snails is confusing and there are many scientific names in use. There has also been debate regarding whether or not ''Cipangopaludina chinensis malleata'' and '' Cipangopaludina japonica'' in North America are synonymous and simply different phenotypes of the same species. For example USGS database considers the two as separate species. Smith (2000) argues that '' Cipangopaludina'' is a subgenus of ''Bellamya''; however, because most North ...

Eutrophic
Eutrophication is the process by which an entire body of water, or parts of it, becomes progressively enriched with minerals and nutrients, particularly nitrogen and phosphorus. It has also been defined as "nutrient-induced increase in phytoplankton productivity". Water bodies with very low nutrient levels are termed oligotrophic and those with moderate nutrient levels are termed mesotrophic. Advanced eutrophication may also be referred to as dystrophic and hypertrophic conditions. Eutrophication can affect freshwater or salt water systems. In freshwater ecosystems it is almost always caused by excess phosphorus. In coastal waters on the other hand, the main contributing nutrient is more likely to be nitrogen, or nitrogen and phosphorus together. This depends on the location and other factors. When occurring naturally, eutrophication is a very slow process in which nutrients, especially phosphorus compounds and organic matter, accumulate in water bodies. These nutrients derive f ...

Lake
A lake is an area filled with water, localized in a basin, surrounded by land, and distinct from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, although, like the much larger oceans, they do form part of the Earth's water cycle. Lakes are distinct from lagoons, which are generally coastal parts of the ocean. Lakes are typically larger and deeper than ponds, which also lie on land, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which usually flow in a channel on land. Most lakes are fed and drained by rivers and streams. Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers, where a river channel has widened into a basin. Some parts of the world have many lakes formed by the chaotic drainage patterns left over from the la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Walleye
The walleye (''Sander vitreus'', synonym ''Stizostedion vitreum''), also called the yellow pike or yellow pickerel, is a freshwater perciform fish native to most of Canada and to the Northern United States. It is a North American close relative of the European zander, also known as the pikeperch. The walleye is sometimes called the yellow walleye to distinguish it from the blue walleye, which is a color morph that was once found in the southern Ontario and Quebec regions, but is now presumed extinct. However, recent genetic analysis of a preserved (frozen) 'blue walleye' sample suggests that the blue and yellow walleye were simply phenotypes within the same species and do not merit separate taxonomic classification. In parts of its range in English-speaking Canada, the walleye is known as a pickerel, though the fish is not related to the true pickerels, which are members of the family ''Esocidae''. Walleyes show a fair amount of variation across watersheds. In general, fis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
