Redside Dace
The redside dace (''Clinostomus elongatus'') is a species of ray-finned fish in the family Cyprinidae, found in the United States and Canada. It is unique among minnows, being the only species to routinely feed on flying insects by leaping from water. Thus, it acts as a conduit for nutrient transfers between terrestrial and aquatic environments. The species can be used as an ecosystem health indicator, as it is sensitive to environmental disturbances. Taxonomy American naturalist Jared Potter Kirtland described the redside dace in 1840. Distribution United States The species is most abundant in Pennsylvania, especially in the upper parts of the Susquehanna River drainage. It is also found in the streams of all the Great Lakes, as well as in the Ohio River and the upper parts of the Mississippi River drainage. Canada The distribution of redside dace is mainly limited to Southern Ontario, the Two Tree River on the St. Joseph Island being the only exception. Most populations hav ...

The IUCN Red List Of Threatened Species
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provide sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Committee On The Status Of Endangered Wildlife In Canada
The Committee on the Status of Endangered Wildlife in Canada (COSEWIC, French: Comité sur la situation des espèces en péril au Canada, COSEPAC) is an independent committee of wildlife experts and scientists whose "raison d'être is to identify species at risk" in Canada. It designates the conservation status of wild species. It was established in 1977 to provide a single, scientifically sound classification of wildlife species at risk of extinction. In the 2002 Species at Risk Act, COSEWIC was appointed as the body to identify and assess a species status. Although the status assigned by COSEWIC is not legally binding, it does report its results to the government and the public. The report is influential toward the addition of species to the List of Wildlife Species at Risk by the Minister of the Environment. Risk categories By December 2013 there were "686 wildlife species in various COSEWIC risk categories, including 196 Special Concern (SC), 166 Threatened (T), 302 Endang ...

Dorsal Fin
A dorsal fin is a fin located on the back of most marine and freshwater vertebrates within various taxa of the animal kingdom. Many species of animals possessing dorsal fins are not particularly closely related to each other, though through convergent evolution they have independently evolved external superficial fish-like body plans adapted to their marine environments, including most numerously fish, but also mammals such as cetaceans (whales, dolphins, and porpoises), and even extinct ancient marine reptiles such as various known species of ichthyosaurs. Most species have only one dorsal fin, but some have two or three. Wildlife biologists often use the distinctive nicks and wear patterns which develop on the dorsal fins of large cetaceans to identify individuals in the field. The bony or cartilaginous bones that support the base of the dorsal fin in fish are called ''pterygiophores''. Functions The main purpose of the dorsal fin is to stabilize the animal against rollin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saugeen River
The Saugeen River is located in southern Ontario, Canada, Ontario, Canada. The river begins in the Osprey, Ontario, Osprey Wetland Conservation Lands and flows generally north-west about before exiting into Lake Huron. The river is navigable for some distance, and was once an important barge route. Today the river is best known for its fishing and as a canoe route. The river's name comes from an Ojibwe language, Ojibwa language word ''Zaagiing'', meaning ''outlet''. Another source is more specific, indicating that "Saugeen" is the corrupted form of the Ojibwa word meaning the entrance or mouth of the river. Course From its source in the Osprey, Ontario, Osprey Wetland Conservation Lands, the Saugeen River flows westerly before briefly turning to the north and flowing through the village of Wareham, Ontario, Wareham. After leaving Wareham, the river turns west again before then flowing southwest and crossing Ontario Highway 10. After crossing the highway the Saugeen meanders to th ...

Lake Erie
Lake Erie ( "eerie") is the fourth largest lake by surface area of the five Great Lakes in North America and the eleventh-largest globally. It is the southernmost, shallowest, and smallest by volume of the Great Lakes and therefore also has the shortest average water residence time. At its deepest point Lake Erie is deep. Situated on the International Boundary between Canada and the United States, Lake Erie's northern shore is the Canadian province of Ontario, specifically the Ontario Peninsula, with the U.S. states of Michigan, Ohio, Pennsylvania, and New York on its western, southern, and eastern shores. These jurisdictions divide the surface area of the lake with water boundaries. The largest city on the lake is Cleveland, anchoring the third largest U.S. metro area in the Great Lakes region, after Greater Chicago and Metro Detroit. Other major cities along the lake shore include Buffalo, New York; Erie, Pennsylvania; and Toledo, Ohio. Situated below Lake Huron, Erie's p ...
