Draba Norvegica
''Draba norvegica'' is a species of flowering plant in the mustard family (Brassicaceae) know by the common names Norwegian draba and Norwegian whitlow grass. Description ''Draba norvegica'' is a small cespitose (forming dense clumps or tufts), herbaceous perennial plant with a rosette of leaves from which a simple unbranched or branched, (0.2-)0.4-1.4(-2) dm tall, flowering stem arises. The basal leaves are simple, with hispid hairs, and narrowly oblanceolate in shape. The stem leaves are also covered in hispid hairs. The flowers are arranged into a raceme inflorescence with 5-23-flowers. The flowers have 2 to 4 rays and are white in color. The fruits (siliques) in contrast to the foliage are hairless or nearly so. Distribution and habitat ''Draba norvegica'' occurs along the Atlantic coast of eastern North America and northwestern Europe with disjunct inland populations. In Canada it is found in arctic and subarctic areas growing on gravelly shorelines, ledges, cliffs, and sto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arctic
The Arctic ( or ) is a polar regions of Earth, polar region located at the northernmost part of Earth. The Arctic consists of the Arctic Ocean, adjacent seas, and parts of Canada (Yukon, Northwest Territories, Nunavut), Danish Realm (Greenland), Finland, Iceland, Norway, Russia (Murmansk Oblast, Murmansk, Siberia, Nenets Autonomous Okrug, Nenets Okrug, Novaya Zemlya), Sweden and the United States (Alaska). Land within the Arctic region has seasonally varying snow and sea ice, ice cover, with predominantly treeless permafrost (permanently frozen underground ice) containing tundra. Arctic seas contain seasonal sea ice in many places. The Arctic region is a unique area among Earth's ecosystems. The cultures in the region and the Arctic indigenous peoples have adapted to its cold and extreme conditions. Life in the Arctic includes zooplankton and phytoplankton, fish and marine mammals, birds, land animals, plants and human societies. Arctic land is bordered by the subarctic. De ...

Subarctic
The subarctic zone is a region in the Northern Hemisphere immediately south of the true Arctic, north of humid continental regions and covering much of Alaska, Canada, Iceland, the north of Scandinavia, Siberia, and the Cairngorms. Generally, subarctic regions fall between 50°N and 70°N latitude, depending on local climates. Precipitation is usually low, and vegetation is characteristic of the taiga. Daylight at these latitudes is quite extreme between summer and winter due to its high latitude. Near the summer solstice for instance, subarctic regions can experience an all-night period of either civil, nautical, or astronomical twilight (or in the northern reaches full daylight), but without true night, since the sun never dips more than 18 degrees below the horizon. Noctilucent clouds are best observed within this range of latitude. Climate and soils Subarctic temperatures are above for at least one and at most three months of the year. Precipitation tends to be low du ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Susie Islands
The Susie Islands (The Susies) are a group of thirteen islands off the coast of the North Shore of Lake Superior in the Arrowhead Region of Minnesota. The outermost island is Lucille, and like Susie and Francis islands, it was named for a member of the Falconer family who once lived on Susie, mining its copper ore during the early 1900s. The Nature Conservancy and the Grand Portage Band of the Chippewa Tribe are working cooperatively to ensure that the area will remain intact and that the unique and unusual flora of the islands will survive. Susie Island was previously owned by the Nature Conservancy and held as the Francis Lee Jaques Memorial Preserve and is the home to some of Minnesota's rarest plants, including alpine bistort and slender hairgrass, both species of special concern, mountain or rock cranberry and common bearberry. In 2017, the Nature Conservancy returned the island to the Grand Portage Band of the Chippewa Tribe. Other diverse plant species include Norwe ...

Lake Superior
Lake Superior in central North America is the largest freshwater lake in the world by surface areaThe Caspian Sea is the largest lake, but is saline, not freshwater. and the third-largest by volume, holding 10% of the world's surface fresh water. The northern and westernmost of the Great Lakes of North America, it straddles the Canada–United States border with the province of Ontario to the north and east, and the states of Minnesota to the northwest and Wisconsin and Michigan to the south. It drains into Lake Huron via St. Marys River, then through the lower Great Lakes to the St. Lawrence River and the Atlantic Ocean. Name The Ojibwe name for the lake is ''gichi-gami'' (in syllabics: , pronounced ''gitchi-gami'' or ''kitchi-gami'' in different dialects), meaning "great sea". Henry Wadsworth Longfellow wrote this name as "Gitche Gumee" in the poem ''The Song of Hiawatha'', as did Gordon Lightfoot in his song " The Wreck of the ''Edmund Fitzgerald''". According to oth ...
