Mukwonago River
The Mukwonago River is one of the cleanest and most biologically diverse streams in southeastern Wisconsin. The river is part of the Mukwonago River Watershed which spans 47,500 acres through and around the town of Mukwonago. Fish and Wildlife At least 53 species of fish, including two state listed species, and sixteen species of mussels are found in the Mukwonago River. Ten of the eleven Sunfish found in Wisconsin are present in the river including the threatened Northern Sunfish. All three species of Killifish (Topminnows), including the endangered Starhead Topminnow, can be found. In addition, the river is also home to a high biodiversity of waterfowl, reptiles, amphibians, insects, aquatic plants, and other wetland life. It holds one of the last and largest strands of wild rice in Southeastern Wisconsin. This high level of biodiversity is quite uncommon for a stream of this size and is only comparable to large rivers in Wisconsin like the Mississippi River or Wisconsin Rive ...

Lepomis Peltastes
The northern sunfish (''Lepomis peltastes'') is a species of North American freshwater fish in the sunfish family (Centrarchidae) of order Perciformes. ''Lepomis peltastes'' was traditionally recognized as a subspecies of longear sunfish (''Lepomis megalotis'') but is often considered to be a separate species. However, this change remains controversial. Identification The northern sunfish (''Lepomis peltastes'') and the longear sunfish (''Lepomis megalotis'') contain very few physical variations. Both are generally small, vibrantly scaled fish with bright, elongated opercular flaps which give the fish an appearance of an "ear", which is a key factor in differentiating the two fishes. The opercular flaps of ''Lepomis peltastes'' tend to have an outline of white and red, while ''Lepomis megalotis'' outlines are strictly white. Although each species coloration is nearly identical, the patterns which form from these colors are not. The northern sunfish tends to have more of a later ...

Killifish
A killifish is any of various oviparous (egg-laying) cyprinodontiform fish (including families Aplocheilidae, Cyprinodontidae, Fundulidae, Profundulidae and Valenciidae). All together, there are 1,270 species of killifish, the biggest family being Rivulidae, containing more than 320 species. As an adaptation to living in ephemeral waters, the eggs of most killifish can survive periods of partial dehydration. Many of the species rely on such a diapause, since the eggs would not survive more than a few weeks if entirely submerged in water. The adults of some species, such as ''Kryptolebias marmoratus'', can additionally survive out of the water for several weeks. Most killies are small fish, from , with the largest species growing to just under . The word ''killifish'' is of uncertain origin, but is likely to have come from the Dutch ''kil'' for a kill (small stream). Although ''killifish'' is sometimes used as an English equivalent to the taxonomical term ''Cyprinodontidae'', s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fundulus Dispar
The Starhead topminnow (''Fundulus dispar'') is a native United States species that ranges from the Ouachita River drainage in Louisiana, the Big Black river in Mississippi, and extends northward into the Mississippi River and Lake Michigan basins to the southern Michigan and southern Wisconsin areas. The Starhead topminnow is endangered due to the removal of aquatic vegetation and the continued development of land that infringes on its habitat. Etymology The name ''Fundulus dispar'' comes from the Latin ''fundus'' meaning bottom with ''-ulus'' as a diminutive suffix and ''dispar'' meaning unlike, dissimilar, different, or unequal. Description The Starhead topminnow can be identified by its light olive tan back and upper sides with the lower sides and belly lighter to yellowish in color. It has a series of red to brown lines along its sides, 6 to 8 on females and 3 to 13 on males. There is a prominent dark blotch of color (similar to a teardrop) beneath its eye. The dorsal fin is ...

Mississippi River
The Mississippi River is the second-longest river and chief river of the second-largest drainage system in North America, second only to the Hudson Bay drainage system. From its traditional source of Lake Itasca in northern Minnesota, it flows generally south for to the Mississippi River Delta in the Gulf of Mexico. With its many tributaries, the Mississippi's watershed drains all or parts of 32 U.S. states and two Canadian provinces between the Rocky and Appalachian mountains. The main stem is entirely within the United States; the total drainage basin is , of which only about one percent is in Canada. The Mississippi ranks as the thirteenth-largest river by discharge in the world. The river either borders or passes through the states of Minnesota, Wisconsin, Iowa, Illinois, Missouri, Kentucky, Tennessee, Arkansas, Mississippi, and Louisiana. Native Americans have lived along the Mississippi River and its tributaries for thousands of years. Most were hunter-ga ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wisconsin River
The Wisconsin River is a tributary of the Mississippi River in the U.S. state of Wisconsin. At approximately 430 miles (692 km) long, it is the state's longest river. The river's name, first recorded in 1673 by Jacques Marquette as "Meskousing", is rooted in the Algonquian languages used by the area's American Indian tribes, but its original meaning is obscure. French explorers who followed in the wake of Marquette later modified the name to "Ouisconsin", and so it appears on Guillaume de L'Isle's map (Paris, 1718). This was simplified to "Wisconsin" in the early 19th century before being applied to Wisconsin Territory and finally the state of Wisconsin. The Wisconsin River originates in the forests of the North Woods Lake District of northern Wisconsin, in Lac Vieux Desert near the border of the Upper Peninsula of Michigan. It flows south across the glacial plain of central Wisconsin, passing through Wausau, Stevens Point, and Wisconsin Rapids. In southern Wisconsin it en ...

Invasive Species
An invasive species otherwise known as an alien is an introduced organism that becomes overpopulated and harms its new environment. Although most introduced species are neutral or beneficial with respect to other species, invasive species adversely affect habitats and bioregions, causing ecological, environmental, and/or economic damage. The term can also be used for native species that become harmful to their native environment after human alterations to its food webfor example the purple sea urchin (''Strongylocentrotus purpuratus'') which has decimated kelp forests along the northern California coast due to overharvesting of its natural predator, the California sea otter (''Enhydra lutris''). Since the 20th century, invasive species have become a serious economic, social, and environmental threat. Invasion of long-established ecosystems by organisms is a natural phenomenon, but human-facilitated introductions have greatly increased the rate, scale, and geographic range of ...

Corbicula Fluminea
''Corbicula fluminea'' is a species of freshwater clam native to eastern Asia which has become a successful invasive species throughout North America, South America, and Europe. ''Corbicula fluminea'' is commonly known in the west as the Asian clam or Asiatic clam. In Southeast Asia, ''C. fluminea'' is known as the golden clam, prosperity clam, pygmy clam, or good luck clam. Overview ''Corbicula'' have had global success as an Invasive species, aquatic invasive species, having been introduced to a novel range including South America, North America and Europe. Human industrial activity, such as transport of larvae via ballast water in container ships, has been noted in the literature as a chief invasion vector. A market exists for Asian clams for human consumption in Japan, China, and other countries in the region. According to the United States Geological Survey, ''C. fluminea'' is likely to continue to expand its North American range until it reaches the maximum extent of its l ...

Zebra Mussel
The zebra mussel (''Dreissena polymorpha'') is a small freshwater mussel. The species originates from the lakes of southern Russia and Ukraine, but has been accidentally introduced to numerous other areas and has become an invasive species in many countries worldwide. Since the 1980s, the species has invaded the Great Lakes, Hudson River, and Lake Travis. The species was first described in 1769 by German zoologist Peter Simon Pallas in the Ural, Volga, and Dnieper Rivers. Zebra mussels get their name from a striped pattern commonly seen on their shells, though it is not universally present. They are usually about the size of a fingernail, but can grow to a maximum length around . Shells are D-shaped, and attached to the substrate with strong byssal fibers, which come out of their umbo on the dorsal (hinged) side. Ecology Zebra mussels and the closely related and ecologically similar quagga mussels are filter-feeding organisms; they remove particles from the water column. ...

Lythrum Salicaria
''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.
