Scarecrow Island
Scarecrow Island is a small, 7-acre (0.03-km2) island in Lake Huron. It forms the southern limit of Thunder Bay and helps define the harbor of Alpena, Michigan. It is part of Sanborn Township, in Alpena County, Michigan. In recognition of Scarecrow Island's importance as a traditional nesting site for colonial waterbirds such as cormorants, herons, gulls, and terns, it received protection as one of eight islands in the Michigan Islands National Wildlife Refuge in 1943. In 1970, it was designated as one of three islands in the Michigan Islands Wilderness. The island is administered as a satellite of the Shiawassee National Wildlife Refuge. Adjacent waters of Thunder Bay became part of the Thunder Bay National Marine Sanctuary in 2000. Located off Hardwood Point, Scarecrow Island is situated in the center of a region rich in fish. A 2002 study conducted the U.S. Fish and Wildlife Service documented the occurrence of seven species of fish in the immediate vicinity of t ...

Lake Huron
Lake Huron ( ) is one of the five Great Lakes of North America. Hydrology, Hydrologically, it comprises the easterly portion of Lake Michigan–Huron, having the same surface elevation as Lake Michigan, to which it is connected by the , Straits of Mackinac. It is shared on the north and east by the Canadian province of Ontario and on the south and west by the U.S. state of Michigan. The name of the lake is derived from early French explorers who named it for the Wyandot people, Huron people inhabiting the region. The Huronian glaciation was named from evidence collected from Lake Huron region. The northern parts of the lake include the North Channel (Ontario), North Channel and Georgian Bay. Saginaw Bay is located in the southwest corner of the lake. The main inlet is the St. Marys River (Michigan–Ontario), St. Marys River, and the main outlet is the St. Clair River. Geography By surface area, Lake Huron is the second-largest of the Great Lakes, with a surface area of — ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shiawassee National Wildlife Refuge
The Shiawassee National Wildlife Refuge is a National Wildlife Refuge in Saginaw County managed by the United States Fish and Wildlife Service. It is located in the central portion of the lower peninsula of the U.S. state of Michigan, approximately 25 miles (40 km) south of the Saginaw Bay in Lake Huron and five miles (8 km) south of the city of Saginaw in the county's Spaulding and James townships. It was established in 1953 to provide habitat for migratory waterfowl. Known locally as the Shiawassee Flats, the refuge lies in the Saginaw Bay watershed, historically one of the largest and most productive wetland ecosystems in Michigan. The Bad, Flint, and Cass Rivers flow into the Shiawassee River in the refuge. Here also the Shiawassee converges with the Tittabawassee River to form the Saginaw River. Wildlife and Habitat Refuge habitats include riparian, floodplain/bottomland hardwood forests, and emergent marshes, as well as shallow managed wetlands and croplands. Ove ...

Protected Areas Of Alpena County, Michigan
Protection is any measure taken to guard a thing against damage caused by outside forces. Protection can be provided to physical objects, including organisms, to systems, and to intangible things like civil and political rights. Although the mechanisms for providing protection vary widely, the basic meaning of the term remains the same. This is illustrated by an explanation found in a manual on electrical wiring: Some kind of protection is a characteristic of all life, as living things have evolved at least some protective mechanisms to counter damaging environmental phenomena, such as ultraviolet light. Biological membranes such as bark on trees and skin on animals offer protection from various threats, with skin playing a key role in protecting organisms against pathogens and excessive water loss. Additional structures like scales and hair offer further protection from the elements and from predators, with some animals having features such as spines or camouflage servi ...

Wisconsin Glaciation
The Wisconsin Glacial Episode, also called the Wisconsin glaciation, was the most recent glacial period of the North American ice sheet complex. This advance included the Cordilleran Ice Sheet, which nucleated in the northern North American Cordillera; the Innuitian ice sheet, which extended across the Canadian Arctic Archipelago; the Greenland ice sheet; and the massive Laurentide Ice Sheet, which covered the high latitudes of central and eastern North America. This advance was synchronous with global glaciation during the last glacial period, including the North American alpine glacier advance, known as the Pinedale glaciation. The Wisconsin glaciation extended from approximately 75,000 to 11,000 years ago, between the Sangamonian Stage and the current interglacial, the Holocene. The maximum ice extent occurred approximately 25,000–21,000 years ago during the last glacial maximum, also known as the ''Late Wisconsin'' in North America. This glaciation radically altered the ...

Relict (geology)
A relict, in geology, is a structure or mineral from a parent rock that did not undergo metamorphic change when the surrounding rock did, or a rock that survived a destructive geologic process. Some geologic processes are destructive or transformative of structures or minerals, and when a process is not complete or does not completely destroy certain features, the left-over feature is a relict of what was there before. For example, relict permafrost is an area of ancient permafrost which remains despite a change in climate which would prohibit new permafrost from forming or it could be a fragment of ancient soil or sediment found in a younger stratum. A relict sediment is an area of ancient sediment which remains unburied despite changes in the surrounding environment. In pedology, the study of soil formation and classification, ancient soil found in the geologic record is called a paleosol, material formed in the distant past on what was then the surface. A relict paleosol is stil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Chub
The lake chub (''Couesius plumbeus'') is a freshwater cyprinid fish found in Canada and in parts of the United States. Of all North American minnows, it is the one with the northernmost distribution. Its genus, ''Couesius'' is considered monotypic today. The genus was named after Elliott Coues, who collected the holotype specimen. Description The body is fusiform and somewhat elongate. It is usually 100 to 175 mm (4 to 7 in) long, where the maximum length is approximately 225 mm (9 in). The back is olive-brown or dark brown, and the sides are leaden silver, hence the word ''plumbeus'', referring to lead, in the scientific name of this fish. The snout is blunt and projects slightly beyond the upper lip. The corners of the mouth each bear a small barbel. The scales are small but well visible, and some may be black and form isolated dark spots on the lower sides. The dorsal, pelvic and anal fins each have 8 rays. The pectoral fins are broad and have 13-18, but more ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Round Whitefish
The round whitefish (''Prosopium cylindraceum'') is a freshwater species of fish that is found in lakes from Alaska to New England, including the Great Lakes. It has an olive-brown back with light silvery sides and underside and its length is generally between . They are bottom feeders, feeding mostly on invertebrates, such as crustaceans, insect larvae, and fish eggs. Some other fish species, like white sucker in turn eat their eggs. Lake trout, northern pike and burbot are natural predators. Other common names of the round whitefish are Menominee, pilot fish, frost fish, round-fish, and Menominee whitefish. The common name "round whitefish" is also sometimes used to describe ''Coregonus huntsmani'', a salmonid more commonly known as the Atlantic whitefish. While it was once common, numbers have been decreasing in the last century due to a number of possible causes. The round whitefish is now protected in some states, such as New York, under the Endangered Species Act from h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Mos ...
