Boreal Ecosystem
A boreal ecosystem is an ecosystem with a subarctic climate located in the Northern Hemisphere, approximately between 50° to 70°N latitude. These ecosystems are commonly known as taiga and are located in parts of North America, Europe, and Asia. The ecosystems that lie immediately to the south of boreal zones are often called hemiboreal. There are a variety of processes and species that occur in these areas as well. The Köppen symbols of boreal ecosystems are Dfc, Dwc, Dfd, and Dwd. Boreal Species The species within boreal ecosystems varies as it consists of both terrestrial and aquatic habitats. The species composition include many generalized and less specialized feeders. From the equator to the poles, species richness decreases, and there is a negative relationship with species richness changes as climate changes. However, despite not being as biodiverse as tropical systems, this area has a variety of species. Boreal ecosystems are filled with a multitude of flora speci ...

Driftless Area National Wildlife Refuge
Driftless Area National Wildlife Refuge is a United States National Wildlife Refuge in northeastern Iowa, southwestern Wisconsin and northwestern Illinois. It is a non-contiguous collection of parcels in the vicinity of the Upper Mississippi River National Wildlife and Fish Refuge. The refuge was established in 1989 to help the recovery of two federally listed species: the endangered Iowa Pleistocene Snail and threatened plant Northern Wild Monkshood. Although the refuge was established to protect the snail and flower, an entire rare community of plants and animals is preserved on these sites. The U.S. Fish and Wildlife Service manages the refuge as part of the National Wildlife Refuge system. Currently, the refuge consists of nine sites totaling in four counties of Iowa only. In descending order of land area they are Clayton, Dubuque, Jackson, and Allamakee counties. Geology Portions of Iowa, Wisconsin, Minnesota and Illinois contain unusual geology.

Bixby State Preserve
Bixby State Preserve is a nature reserve located in southwestern Clayton County, Iowa, in the midwestern United States. It is located north of Edgewood. It is operated by the Iowa Department of Natural Resources as one of the Iowa state preserves. Bixby State Preserve is one of the few places in the world to contain algific talus slopes and consequently has an ecosystem encountered in only a few other sites, all in the Driftless Area. They are mainly elsewhere in Iowa, but also in southeastern Minnesota, southwestern Wisconsin and northwestern Illinois. In winter and early spring comparatively warm air rises from the elaborate system of sinkholes, causing cold moist air to be drawn into the north-facing talus slopes and sent through fissures into ice cave An ice cave is any type of natural cave (most commonly lava tubes or limestone caves) that contains significant amounts of perennial (year-round) ice. At least a portion of the cave must have a temperature below 0 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sugar Maple
''Acer saccharum'', the sugar maple, is a species of flowering plant in the soapberry and lychee family Sapindaceae. It is native to the hardwood forests of eastern Canada and eastern United States. Sugar maple is best known for being the primary source of maple syrup and for its brightly colored fall foliage. It may also be known as "rock maple", "sugar tree", "birds-eye maple", "sweet maple", "curly maple", or "hard maple", particularly when referring to the wood. Description ''Acer saccharum'' is a deciduous tree normally reaching heights of , and exceptionally up to . A 10-year-old tree is typically about tall. As with most trees, forest-grown sugar maples form a much taller trunk and narrower canopy than open-growth ones. The leaves are deciduous, up to long and wide, palmate, with five lobes and borne in opposite pairs. The basal lobes are relatively small, while the upper lobes are larger and deeply notched. In contrast with the angular notching of the silver map ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Basswood
''Tilia americana'' is a species of tree in the family Malvaceae, native to eastern North America, from southeast Manitoba east to New Brunswick, southwest to northeast Oklahoma, southeast to South Carolina, and west along the Niobrara River to Cherry County, Nebraska. It is the sole representative of its genus in the Western Hemisphere, assuming ''T. caroliniana'' is treated as a subspecies or local ecotype of ''T. americana''. Common names include American basswood and American linden. Description The American basswood is a medium-sized to large deciduous tree reaching a height of exceptionally with a trunk diameter of at maturity. It grows faster than many North American hardwoods, often twice the annual growth rate of American beech and many birch species. Life expectancy is around 200 years, with flowering and seeding generally occurring between 15 and 100 years, though occasionally seed production may start as early as eight years. The crown is domed, the branc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birch
A birch is a thin-leaved deciduous hardwood tree of the genus ''Betula'' (), in the family Betulaceae, which also includes alders, hazels, and hornbeams. It is closely related to the beech- oak family Fagaceae. The genus ''Betula'' contains 30 to 60 known taxa of which 11 are on the IUCN 2011 Red List of Threatened Species. They are a typically rather short-lived pioneer species widespread in the Northern Hemisphere, particularly in northern areas of temperate climates and in boreal climates. Description Birch species are generally small to medium-sized trees or shrubs, mostly of northern temperate and boreal climates. The simple leaves are alternate, singly or doubly serrate, feather-veined, petiolate and stipulate. They often appear in pairs, but these pairs are really borne on spur-like, two-leaved, lateral branchlets. The fruit is a small samara, although the wings may be obscure in some species. They differ from the alders (''Alnus'', another genus in the family) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
