Pakowki Lake
Pakowki Lake is an endorheic lake in Alberta, Canada located south of Etzikom, Alberta and not far north is the former town site of Pakowki which may have received its name from the lake. It is located in the prairies of southern Alberta, at an elevation of , in the County of Forty Mile No. 8. It is fed by a number of coulees and creeks, such as Etzikom Coulee, Irrigation Creek, Erickson Coulee, Ketchum Creek, Canal Creek, Bond Coulee and Bryant Coulee, and has no outflow. Reaching a maximum extent of , it is one of the largest lakes in the province. The name means "bad water" in Blackfoot language, named so for the bad smell caused by the lack of an outflow. While it is the largest water body in southern Alberta, its waters are intermittent, and it can be classified as a slough. In times of flooding, the lake overflows through a channel into the Milk River, which flows south of the lake. Conservation The ''Pakowki Lake Provincial Bird Sanctuary'' is established on and around ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
County Of Forty Mile No
A county is a geographic region of a country used for administrative or other purposesChambers Dictionary, L. Brookes (ed.), 2005, Chambers Harrap Publishers Ltd, Edinburgh in certain modern nations. The term is derived from the Old French denoting a jurisdiction under the sovereignty of a count (earl) or a viscount.The Oxford Dictionary of English Etymology, C. W. Onions (Ed.), 1966, Oxford University Press Literal equivalents in other languages, derived from the equivalent of "count", are now seldom used officially, including , , , , , , , and ''zhupa'' in Slavic languages; terms equivalent to commune/community are now often instead used.

Double-crested Cormorant
The double-crested cormorant (''Nannopterum auritum'') is a member of the cormorant family of water birds. It is found near rivers and lakes, and in coastal areas, and is widely distributed across North America, from the Aleutian Islands in Alaska down to Florida and Mexico. Measuring in length, it is entirely black except for a bare patch of orange-yellow facial skin and some extra plumage that it exhibits in the breeding season, when it grows a double crest in which black feathers are mingled with white. Five subspecies are recognized. It mainly eats fish and hunts by swimming and diving. Its feathers, like those of all cormorants, are not waterproof and it must spend time drying them out after spending time in the water. Once threatened by the use of DDT, the numbers of this bird have increased markedly in recent years. Taxonomy The double-crested cormorant was described by René Primevère Lesson in 1831. It was formerly classified in the genus '' Phalacrocorax'', but a 2014 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chenopodium
''Chenopodium'' is a genus of numerous species of perennial or annual herbaceous flowering plants known as the goosefoots, which occur almost anywhere in the world. It is placed in the family Amaranthaceae in the APG II system; older classification systems, notably the widely used Cronquist system, separate it and its relatives as Chenopodiaceae, but this leaves the rest of the Amaranthaceae polyphyletic. However, among the Amaranthaceae, the genus ''Chenopodium'' is the namesake member of the subfamily Chenopodioideae. Description The species of ''Chenopodium'' (s.str., description according to Fuentes et al. 2012) are annual or perennial herbs, shrubs or small trees. They generally rely on alkaline soil. They are nonaromatic, but sometimes fetid. The young stems and leaves are often densely covered by vesicular globose hairs, thus looking farinose. Characteristically, these trichomes persist, collapsing later and becoming cup-shaped. The branched stems grow erect, ascen ...

Tradescantia Occidentalis
''Tradescantia occidentalis'', the prairie spiderwort or western spiderwort, is a plant in the dayflower family, Commelinaceae. It is common and widespread across the western Great Plains of the United States, as well as in Arizona, New Mexico, southern Utah, and Sonora, but is listed as a threatened species in Canada. Like in a few other species of ''Tradescantia'', the cells of the stamen hairs of Western spiderwort are normally colored blue, but when exposed to neutron radiation or other forms of ionizing radiation, the cells mutate and change color to pink. Thus the plant can be used as a bioassay for radiation.

Tradescantia
''Tradescantia'' () is a genus of 85 species of herbaceous perennial plant, perennial wildflowers in the family Commelinaceae, native to the Americas from southern Canada to northern Argentina, including the West Indies. Members of the genus are known by many common names, including inchplant, wandering jew, spiderwort, and dayflower. ''Tradescantia'' grow , and are commonly found individually or in clumps in wooded areas and open fields. They were introduced into Europe as ornamental plants in the 17th century and are now grown in many parts of the world. Some species have become naturalized in regions of Europe, Asia, Africa, and Australia, and on some oceanic islands. The genus's many species are of interest to cytogenetics because of evolutionary changes in the structure and number of their chromosomes. They have also been used as bioindicators for the detection of natural environment, environmental mutagens. Some species have become pest (organism), pests to cultivated crop ...

Grassland
A grassland is an area where the vegetation is dominated by grasses (Poaceae). However, sedge (Cyperaceae) and rush (Juncaceae) can also be found along with variable proportions of legumes, like clover, and other herbs. Grasslands occur naturally on all continents except Antarctica and are found in most ecoregions of the Earth. Furthermore, grasslands are one of the largest biomes on earth and dominate the landscape worldwide. There are different types of grasslands: natural grasslands, semi-natural grasslands, and agricultural grasslands. They cover 31–69% of the Earth's land area. Definitions Included among the variety of definitions for grasslands are: * "...any plant community, including harvested forages, in which grasses and/or legumes make up the dominant vegetation." * "...terrestrial ecosystems dominated by herbaceous and shrub vegetation, and maintained by fire, grazing, drought and/or freezing temperatures." (Pilot Assessment of Global Ecosystems, 2000) * "A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Porcupine
Porcupines are large rodents with coats of sharp spines, or quills, that protect them against predation. The term covers two families of animals: the Old World porcupines of family Hystricidae, and the New World porcupines of family, Erethizontidae. Both families belong to the infraorder Hystricognathi within the profoundly diverse order Rodentia and display superficially similar coats of rigid or semi-rigid quills, which are modified hairs composed of keratin. Despite this, the two groups are distinct from one another and are not closely related to each other within the Hystricognathi. The largest species of porcupine is the third-largest living rodent in the world, after the capybara and beaver. The Old World porcupines (Hystricidae) live in Italy, Asia (western and southern), and most of Africa. They are large, terrestrial, and strictly nocturnal. The New World porcupines (Erethizontidae) are indigenous to North America and northern South America. They live in wooded area ...

Striped Skunk
The striped skunk (''Mephitis mephitis'') is a skunk of the genus '' Mephitis'' that occurs across much of North America, including southern Canada, the United States, and northern Mexico. It is currently listed as least concern by the IUCN on account of its wide range and ability to adapt to human-modified environments. Striped skunks are polygamous omnivores with few natural predators, save for birds of prey. Like all skunks, they possess highly developed musk-filled scent glands to ward off predators. They have a long history of association with humans, having been trapped and captively bred for their fur and kept as pets. The striped skunk is one of the most recognizable of North America's animals, and is a popular figure in cartoons and children's books. Taxonomy The striped skunk was first formally named by Johann Christian Daniel von Schreber as ''Viverra mephitis''. The type locality is in eastern Canada. Evolution and subspecies The earliest fossil finds attributable ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coyote
The coyote (''Canis latrans'') is a species of canis, canine native to North America. It is smaller than its close relative, the wolf, and slightly smaller than the closely related eastern wolf and red wolf. It fills much of the same ecological niche as the golden jackal does in Eurasia. The coyote is larger and more predatory and was once referred to as the American jackal by a behavioral ecologist. Other historical names for the species include the prairie wolf and the brush wolf. The coyote is listed as Least Concern, least concern by the International Union for Conservation of Nature, due to its wide distribution and abundance throughout North America. The species is versatile, able to adapt to and expand into environments modified by humans. It is enlarging its range by moving into urban areas in the eastern U.S. and Canada. The coyote was sighted in eastern Panama (across the Panama Canal from their home range) for the first time in 2013. The coyote has 19 recognized sub ...

Badger
Badgers are short-legged omnivores in the family Mustelidae (which also includes the otters, wolverines, martens, minks, polecats, weasels, and ferrets). Badgers are a polyphyletic rather than a natural taxonomic grouping, being united by their squat bodies and adaptions for fossorial activity. All belong to the caniform suborder of carnivoran mammals. The fifteen species of mustelid badgers are grouped in four subfamilies: four species of Melinae (genera ''Meles'' and ''Arctonyx'') including the European badger, five species of Helictidinae (genus ''Melogale'') or ferret-badger, the honey badger or ratel Mellivorinae (genus ''Mellivora''), and the American badger Taxideinae (genus ''Taxidae''). Badgers include the most basal mustelids; the American badger is the most basal of all, followed successively by the ratel and the Melinae; the estimated split dates are about 17.8, 15.5 and 14.8 million years ago, respectively. The two species of Asiatic stink badgers of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pronghorn
The pronghorn (, ) (''Antilocapra americana'') is a species of artiodactyl (even-toed, hoofed) mammal indigenous to interior western and central North America. Though not an antelope, it is known colloquially in North America as the American antelope, prong buck, pronghorn antelope and prairie antelope, because it closely resembles the antelopes of the Old World and fills a similar ecological niche due to parallel evolution. It is the only surviving member of the family Antilocapridae. During the Pleistocene epoch, about 11 other antilocaprid species existed in North America.Smithsonian Institution. North American MammalsPronghorn ''Antilocapra americana''/ref> Three other genera (''Capromeryx'', '' Stockoceros'' and ''Tetrameryx'') existed when humans entered North America but are now extinct. As a member of the superfamily Giraffoidea, the pronghorn's closest living relatives are the giraffe and okapi. See Fig. S10 in Supplementary Information. The Giraffoidea are in tu ...

American Bittern
The American bittern (''Botaurus lentiginosus'') is a species of wading bird in the heron family. It has a Nearctic distribution, breeding in Canada and the northern and central parts of the United States, and wintering in the U.S. Gulf Coast states, all of Florida into the Everglades, the Caribbean islands and parts of Central America. It is a well-camouflaged, solitary brown bird that unobtrusively inhabits marshes and the coarse vegetation at the edge of lakes and ponds. In the breeding season it is chiefly noticeable by the loud, booming call of the male. The nest is built just above the water, usually among bulrushes and cattails, where the female incubates the clutch of olive-colored eggs for about four weeks. The young leave the nest after two weeks and are fully fledged at six or seven weeks. The American bittern feeds mostly on fish but also eats other small vertebrates as well as crustaceans and insects. It is fairly common over its wide range, but its numbers are t ...
