Turtle Mountain Provincial Park
Turtle Mountain Provincial Park is a provincial park located in the southwestern portion of the Canadian province of Manitoba. Within it are the Adam Lake and Max Lake campgrounds. The park is known for its bike trails, fishing, back country cabins and canoe routes. The park is very popular with families and outdoor enthusiasts. The park is named after the numerous painted turtles found in the area."Turtle Mountain Provincial Park". The Canadian Encyclopedia, 23 May 2019, Historica Canada. https://www.thecanadianencyclopedia.ca/en/article/turtle-mountain-provincial-park. Accessed 24 September 2019. The turtles can be seen throughout the warmer months sun bathing near permanent ponds or lakes in the park. In late spring and early summer the females can be seen laying eggs in sandy soil throughout the park. The turtles live in the shallow lakes in the park.Braman, D., Sweet, A., & Lerbekmo, J. (1999).

Provincial Park
Ischigualasto Provincial Park A provincial park (or territorial park) is a park administered by one of the provinces of a country, as opposed to a national park. They are similar to state parks in other countries. They are typically open to the public for recreation. Their environment may be more or less strictly protected. Argentina Provincial parks ( es, Parques Provinciales) in the Misiones Province of Argentina include the Urugua-í Provincial Park and Esmeralda Provincial Park. The Ischigualasto Provincial Park, also called Valle de la Luna ("Valley of the Moon" or "Moon Valley"), due to its otherworldly appearance, is a provincial protected area in the north-east of San Juan Province, north-western Argentina. The Aconcagua Provincial Park is in Mendoza Province. The highest point is the north summit of the Cerro Aconcagua at . The Parque Provincial Pereyra Iraola is the largest urban park in the Buenos Aires Province. It is the richest center of biodiversity in the pro ...

Red River Colony
The Red River Colony (or Selkirk Settlement), also known as Assiniboia, Assinboia, was a colonization project set up in 1811 by Thomas Douglas, 5th Earl of Selkirk, on of land in British North America. This land was granted to Douglas by the Hudson's Bay Company in the Selkirk Concession. It included portions of Rupert's Land, or the watershed of Hudson Bay, bounded on the north by the line of 52° N latitude roughly from the Assiniboine River east to Lake Winnipegosis. It then formed a line of 52° 30′ N latitude from Lake Winnipegosis to Lake Winnipeg, and by the Winnipeg River, Lake of the Woods and Rainy River (Minnesota–Ontario), Rainy River. West of the Selkirk Concession, it is roughly formed by the current boundary between Saskatchewan and Manitoba. These covered portions consisted of present-day southern Manitoba, northern Minnesota, and eastern North Dakota, in addition to small parts of eastern Saskatchewan, northwestern Ontario, and northeastern South Da ...

Luvisol
Luvisols are a group of soils, comprising one of the 32 Reference Soil Groups in the international system of soil classification, the World Reference Base for Soil Resources The World Reference Base for Soil Resources (WRB) is an international soil classification system for naming soils and creating legends for soil maps. The currently valid version is the fourth edition 2022. It is edited by a working group of the Inte ... (WRB). They are widespread, especially in temperate climates, and are generally fertile. Luvisols are widely used for agriculture. Distribution Luvisols cover 500–600 million ha of land area, mainly in the temperate zones. They form on a wide variety of mineral parent materials. In Mediterranean regions, the formation of hematite can produce red-coloured Chromic Luvisols. Description and formation The main characteristic of Luvisols is an argic horizon, a subsurface zone with higher clay content than the material above it. This typically arises as clay is was ...

Chernozem
Chernozem (from rus, чернозём, p=tɕɪrnɐˈzʲɵm, r=chernozyom; "black ground"), also called black soil, is a black-colored soil containing a high percentage of humus (4% to 16%) and high percentages of phosphorus and ammonia compounds. Chernozem is very fertile soil and can produce high agricultural yields with its high moisture storage capacity. Chernozems are a Reference Soil Group of the World Reference Base for Soil Resources (WRB). Distribution The name comes from the Russian terms for black and soil, earth or land (''chorny'' + ''zemlya''). The soil, rich in organic matter presenting a black color, was first identified by Russian geologist Vasily Dokuchaev in 1883 in the tallgrass steppe or prairie of European Russia. Chernozem cover about 230 million hectares of land. There are two "chernozem belts" in the world. One is the Eurasian steppe which extends from eastern Croatia (Slavonia), along the Danube (northern Serbia, northern Bulgaria ( Danubian Pla ...

Paleocene
The Paleocene, ( ) or Palaeocene, is a geological epoch (geology), epoch that lasted from about 66 to 56 mya (unit), million years ago (mya). It is the first epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), Era. The name is a combination of the Ancient Greek ''palaiós'' meaning "old" and the Eocene Epoch (which succeeds the Paleocene), translating to "the old part of the Eocene". The epoch is bracketed by two major events in Earth's history. The K–Pg extinction event, brought on by Chicxulub impact, an asteroid impact and possibly volcanism, marked the beginning of the Paleocene and killed off 75% of living species, most famously the non-avian dinosaurs. The end of the epoch was marked by the Paleocene–Eocene Thermal Maximum (PETM), which was a major climatic event wherein about 2,500–4,500 gigatons of carbon were released into the atmosphere and ocean systems, causing a spike in global temperatures and ocean acidification. In the Pal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dinoflagellate
The dinoflagellates (Greek δῖνος ''dinos'' "whirling" and Latin ''flagellum'' "whip, scourge") are a monophyletic group of single-celled eukaryotes constituting the phylum Dinoflagellata and are usually considered algae. Dinoflagellates are mostly marine plankton, but they also are common in freshwater habitats. Their populations vary with sea surface temperature, salinity, and depth. Many dinoflagellates are photosynthetic, but a large fraction of these are in fact mixotrophic, combining photosynthesis with ingestion of prey (phagotrophy and myzocytosis). In terms of number of species, dinoflagellates are one of the largest groups of marine eukaryotes, although substantially smaller than diatoms. Some species are endosymbionts of marine animals and play an important part in the biology of coral reefs. Other dinoflagellates are unpigmented predators on other protozoa, and a few forms are parasitic (for example, ''Oodinium'' and ''Pfiesteria''). Some dinoflagellates pro ...

Pleistocene
The Pleistocene ( , often referred to as the ''Ice age'') is the geological Epoch (geology), epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing Great American Interchang ...

Fluvioglacial Deposits
Glaciofluvial deposits or Glacio-fluvial sediments consist of boulders, gravel, sand, silt and clay from ice sheets or glaciers. They are transported, sorted and deposited by streams of water. The deposits are formed beside, below or downstream from the ice. They include kames, kame terraces and eskers formed in ice contact and outwash fans and outwash plains below the ice margin. Typically the outwash sediment is carried by fast and turbulent fluvio-glacial meltwater streams, but occasionally it is carried by catastrophic outburst floods. Larger elements such as boulders and gravel are deposited nearer to the ice margin, while finer elements are carried farther, sometimes into lakes or the ocean. The sediments are sorted by fluvial processes. They differ from glacial till, which is moved and deposited by the ice of the glacier, and is unsorted. Ice-contact deposits A subglacial megaflood may cut cavities into the base of the ice. As the flood dies down, sediment is deposited ...

Canadian Prairies
The Canadian Prairies (usually referred to as simply the Prairies in Canada) is a region in Western Canada. It includes the Canadian portion of the Great Plains and the Prairie Provinces, namely Alberta, Saskatchewan, and Manitoba. These provinces are partially covered by grasslands, plains, and lowlands, mostly in the southern regions. The northernmost reaches of the Canadian Prairies are less dense in population, marked by forests and more variable topography. If the region is defined to include areas only covered by prairie land, the corresponding region is known as the Interior Plains. Physical or ecological aspects of the Canadian Prairies extend to northeastern British Columbia, but that area is not included in political use of the term. The prairies in Canada are a temperate grassland and shrubland biome within the prairie ecoregion of Canada that consists of northern mixed grasslands in Alberta, Saskatchewan, southern Manitoba, as well as northern short grasslands in sou ...

Ecoregion
An ecoregion (ecological region) or ecozone (ecological zone) is an ecologically and geographically defined area that is smaller than a bioregion, which in turn is smaller than a biogeographic realm. Ecoregions cover relatively large areas of land or water, and contain characteristic, geographically distinct assemblages of natural communities and species. The biodiversity of flora, fauna and ecosystems that characterise an ecoregion tends to be distinct from that of other ecoregions. In theory, biodiversity or conservation ecoregions are relatively large areas of land or water where the probability of encountering different species and communities at any given point remains relatively constant, within an acceptable range of variation (largely undefined at this point). Three caveats are appropriate for all bio-geographic mapping approaches. Firstly, no single bio-geographic framework is optimal for all taxa. Ecoregions reflect the best compromise for as many taxa as possible. Se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pembina Escarpment
The Pembina Escarpment is a scarp that runs from South Dakota to Manitoba, and forms the western wall of the Red River Valley. The height of the escarpment above the river valley is . Geology The escarpment was originally formed by the undercutting of Cretaceous sandstones (the Dakota Formation) by the ancestral Red River. The escarpment was later steepened by glacial scouring. The escarpment is preserved due to a layer of erosion-resistant shale (the Pierre Formation) on top of the sandstone. The vista today, of wooded hills with small farms tucked into valleys (such as the Pembina Valley), is reminiscent of pastoral sections of New England. Streams flowing off the escarpment have high gradients and a cobble substrate. The final form of the escarpment we know today was not created until the end of the last ice age around 12,000 years ago. During the ice age, much of North America was covered by the Laurentide Ice Sheet. As the ice sheet began to melt and recede, the meltwater ...

Turtle Mountain (plateau)
Turtle Mountain, or the Turtle Mountains, is an area in central North America, in the north-central portion of the U.S. state of North Dakota and southwestern portion of the Canadian province of Manitoba, approximately south of the city of Brandon on provincial highway 10. It is a plateau 2,000 ft (600 m) above sea level, 300 ft to 400 ft (90 m to 120 m) above the surrounding countryside, extending 20 mi (32 km) from north to south and 40 mi (64 km) from east to west. Rising , North Dakota's most prominent peak, Boundary Butte, is located at the western edge of the plateau. It has timber, numerous lakes, and small deposits of low-grade manganese. One of the largest lakes in the Turtle Mountains is Lake Metigoshe, which straddles the international border, with about one-eighth of the lake in Canada. The region is home to Turtle Mountain Provincial Park, a state park, two historic sites, and various hunting and fishing opportunities. Turtle Mou ...
