Agawa Canyon
The Agawa Canyon is a shallow canyon located deep in the sparsely populated Algoma District in Northeastern Ontario, Canada. It was created 1.2 billion years ago by faulting along the Canadian Shield and then enlarged by the erosive action of the Agawa River. The Agawa Canyon Wilderness Park is only accessible by hiking trail or the Agawa Canyon station on the Algoma Central Railway, and is located by rail north west of Sault Ste. Marie. Geography At their highest point, the walls of the Agawa Canyon rise above the river. The park is situated in the transitional zone between the Great Lakes – St. Lawrence Forest region and the Boreal Forest, with diverse and numerous representative flora from both regions present in the canyon. Annual snowfall in the canyon exceeds , with a record snowfall of recorded during the winter of 1989. Four waterfalls dot the canyon's rim and feed the Agawa River. The North and South Black Beaver Falls are high. The tallest waterfall in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Algoma District
Algoma District is a district and census division in Northeastern Ontario in the Canadian province of Ontario. The name was created by an American ethnologist, Henry Rowe Schoolcraft (1793–1864), who was appointed Indian agent to the Ojibwe in Sault Ste. Marie region in 1822. "Al" is derived from Algonquin, while "goma" is a variant of gomee, meaning lake or water. Algoma District has shoreline along Lake Superior and Lake Huron. It has an international border crossing to the American state of Michigan, at Sault Ste. Marie. Historically, it was known for its lumber and mining industries. The rugged scenery of the region has inspired works by Canadian artists, particularly the Group of Seven. They rented a boxcar from the Algoma Central Railway to travel on excursions through this region. History Surviving prehistoric remains in Algoma District are concentrated around waterways. These remains date as far back as the Archaic period. There are also sites from the later Woo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leucanthemum Vulgare
''Leucanthemum vulgare'', commonly known as the ox-eye daisy, oxeye daisy, dog daisy, marguerite (, "common marguerite") and other common names, is a widespread flowering plant native to Europe and the temperate regions of Asia, and an introduced plant to North America, Australia and New Zealand. Description ''L. vulgare'' is a Perennial plant, perennial Herbaceous plant, herb that grows to a height of and has a creeping underground rhizome. The lower parts of the stem are hairy, sometimes densely hairy but more or less wikt:glabrous, glabrous in the lower parts. The largest leaves are at the base of the plant and are long, about wide and have a Petiole (botany), petiole. These leaves have up to 15 teeth, or lobes or both on the edges. The leaves decrease in size up the stem, the upper leaves up to long, lack a petiole and are deeply toothed. The plant bears up to three "flowers" like those of a typical Asteraceae, daisy. Each is a "head" or Pseudanthium, capitulum wide. Eac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moose
The moose (: 'moose'; used in North America) or elk (: 'elk' or 'elks'; used in Eurasia) (''Alces alces'') is the world's tallest, largest and heaviest extant species of deer and the only species in the genus ''Alces''. It is also the tallest, and the second-largest, land animal in North America, falling short only to the American bison in body mass. Most adult male moose have broad, palmate ("open-hand shaped") antlers; other members of the deer family have pointed antlers with a dendritic ("twig-like") configuration. Moose inhabit the circumpolar boreal forests or temperate broadleaf and mixed forests of the Northern Hemisphere, thriving in cooler, temperate areas as well as subarctic climates. Hunting shaped the relationship between moose and humans, both in Eurasia and North America. Prior to the colonial era (around 1600–1700 CE), moose were one of many valuable sources of sustenance for certain tribal groups and First Nations. Hunting and habitat loss hav ...

Goldeneye (duck)
''Bucephala'' is a genus of diving ducks found in the Northern Hemisphere. Taxonomy The genus ''Bucephala'' was introduced in 1858 by American naturalist Spencer Baird with the bufflehead as the type species. The genus name is derived from Ancient Greek , meaning , from , and , , a reference to the crest of the bufflehead making its head look large. The bufflehead was formerly treated as the only member of the genus (sometimes unnecessarily changed to ''Charitonetta'') while the goldeneyes were incorrectly placed in '' Clangula'' (as ''Clangula americana''), the genus of the long-tailed duck, which at that time was placed in '' Harelda''. It may yet be correct to recognise two genera, as the bufflehead and the two goldeneyes are well diverged. In this case, ''Bucephala'' would be restricted to ''B. albeola'' and the name ''Glaucionetta'' (Stejneger, 1885) resurrected for the goldeneyes. Species The three living species are: Known fossil taxa are: * ''Bucephala ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wood Duck
The wood duck or Carolina duck (''Aix sponsa'') is a partially migratory species of perching duck found in North America. The male is one of the most colorful North American waterfowls. Taxonomy The wood duck was Species description, formally described in 1758 by the Swedish naturalist Carl Linnaeus in the 10th edition of Systema Naturae, tenth edition of his ''Systema Naturae'' under the binomial nomenclature, binomial name ''Anas sponsa''. Linnaeus based his account on the "summer duck" from Carolina that had been described and illustrated by the English naturalist Mark Catesby in the first volume of his ''The Natural History of Carolina, Florida and the Bahama Islands'' that was published between 1729 and 1731. Linnaeus specified the type locality (biology), type locality as North America but this has been restricted to Carolina following Catesby. The wood duck is now placed together with the mandarin duck in the genus ''Aix (bird), Aix'' that was introduced in 1828 by th ...

Merganser
''Mergus'' is the genus of the typical mergansers ( ) fish-eating ducks in the subfamily Anatinae. The genus name is a Latin word used by Pliny the Elder and other Roman authors to refer to an unspecified waterbird. The common merganser (''Mergus merganser'') and red-breasted merganser (''M. serrator'') have broad ranges in the northern hemisphere. The Brazilian merganser (''M. octosetaceus'') is a South American duck, and one of the six most threatened waterfowl in the world, with possibly fewer than 250 birds in the wild. The scaly-sided merganser or "Chinese merganser" (''M. squamatus'') is an endangered species. It lives in temperate East Asia, breeding in the north and wintering in the south. The hooded merganser (''Lophodytes cucullatus'', formerly known as ''Mergus cucullatus'') is not of this genus but is closely related. The other "aberrant" merganser, the smew (''Mergellus albellus''), is phylogenetically closer to goldeneyes (''Bucephala''). Although they are se ...

Otter
Otters are carnivorous mammals in the subfamily Lutrinae. The 13 extant otter species are all semiaquatic, aquatic, or marine. Lutrinae is a branch of the Mustelidae family, which includes weasels, badgers, mink, and wolverines, among other animals. Otters' habitats include dens known as holts or couches, with their social structure described by terms such as dogs or boars for males, bitches or sows for females, and pups or cubs for offspring. Groups of otters can be referred to as a bevy, family, lodge, romp, or raft when in water, indicating their social and playful characteristics. Otters are known for their distinct feces, termed spraints, which can vary in smell from freshly mown hay to putrefied fish. Otters exhibit a varied life cycle with a gestation period of about 60–86 days, and offspring typically stay with their family for a year. They can live up to 16 years, with their diet mainly consisting of fish and sometimes frogs, birds, or shellfish, depending ...

Beaver
Beavers (genus ''Castor'') are large, semiaquatic rodents of the Northern Hemisphere. There are two existing species: the North American beaver (''Castor canadensis'') and the Eurasian beaver (''C. fiber''). Beavers are the second-largest living rodents, after capybaras, weighing up to . They have stout bodies with large heads, long chisel-like incisors, brown or gray fur, hand-like front feet, webbed back feet, and tails that are flat and scaly. The two species differ in skull and tail shape and fur color. Beavers can be found in a number of freshwater habitats, such as rivers, streams, lakes and ponds. They are herbivorous, consuming tree bark, aquatic plants, grasses and sedges. Beavers build dams and lodges using tree branches, vegetation, rocks and mud; they chew down trees for building material. Dams restrict water flow, forming ponds, and lodges (usually built in ponds) serve as shelters. Their infrastructure creates wetlands used by many other species, a ...

Aster (genus)
''Aster'' is a genus of perennial flowering plants in the family Asteraceae. Its circumscription has been narrowed, and it now encompasses around 170 species, all but one of which are restricted to Eurasia; many species formerly in ''Aster'' are now in other genera of the tribe Astereae. '' Aster amellus'' is the type species of the genus and the family Asteraceae. The name ''Aster'' comes from the Ancient Greek word (), meaning 'star', referring to the shape of the flower head. Many species and a variety of hybrids and varieties are popular as garden plants because of their attractive and colourful flowers. 'Aster' species are used as food plants by the larvae of a number of Lepidoptera species—see list of Lepidoptera that feed on ''Aster''. Asters can grow in all hardiness zones. Circumscription The genus ''Aster'' once contained nearly 600 species in Eurasia and North America, but after morphologic and molecular research on the genus during the 1990s, it was decide ...

Oenothera
''Oenothera'' is a genus of about 145 species of herbaceous flowering plants native to the Americas. It is the type genus of the family Onagraceae. Common names include evening primrose, suncups, and sundrops. They are not closely related to the true primroses (genus ''Primula''). Description The species vary in size from small alpine plants 10 centimeters tall, such as ''O. acaulis'' from Chile, to vigorous lowland species growing to 3 meters, such as ''O. stubbei'' from Mexico. The leaves form a basal rosette at ground level and spiral up to the flowering stems. The blades are dentate or deeply lobed (pinnatifid). The flowers of many species open in the evening, hence the name "evening primrose". They may open in under a minute. Most species have yellow flowers, but some have white, purple, pink, or red. Most native desert species are white. '' Oenothera caespitosa'', a species of western North America, produces white flowers that turn pink with age. One of the most distinct ...
