Hockley Valley Provincial Nature Reserve
Hockley Valley Provincial Nature Reserve is a nature reserve located on the Niagara Escarpment within the township of Mono, Ontario, Canada. It is managed by Ontario Parks. Approximately 80% of the Cannings Falls Area of Natural and Scientific Interest is within the borders of the park; land acquisitions are planned to encompass it entirely. The Bruce Trail links the reserve to other protected areas of the Niagara Escarpment. Landform The topography of the area was greatly influenced by glacial processes, followed by fluvial erosion. The reserve is characterized by a till moraine and other glacial features, such as kames and kettles. A deeply cut tributary valley to the Nottawasaga River bisects the reserve through its centre. The Niagara Escarpment's dolomite caprock (the Amabel Formation) can be seen in the upper parts of the gorge; rapids and waterfalls expose stratigraphic succession down to the Queenston Shale. Flora and fauna Within the reserve, 417 species of vascular ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nottawasaga River
The Nottawasaga River is a river in Simcoe County and Dufferin County in Central Ontario, Canada. It is part of the Great Lakes Basin, and is a tributary of Lake Huron. The river flows from the Orangeville Reservoir in the town of Orangeville, Dufferin County, through the Niagara Escarpment and the Minesing Wetlands, the latter a wetland of international significance (Ramsar Convention site), and empties into Nottawasaga Bay, an inlet of Georgian Bay on Lake Huron, at the town of Wasaga Beach, Simcoe County. The river takes its name from the Ojibwe word "Nottawasaga". ''Nottawa'' (or ''Naadowe'' in modern orthography) means "Iroquois" and ''saga'' (''zaagi'' in modern orthography) means "mouth of the river"; the word "Nottawasaga" (''Naddowe-zaagi'' in modern orthography) was used by Algonquin scouts as a warning if they saw Iroquois raiding parties approaching their villages. Thus,the name of the river, in Ojibwe is ''Naadawe-zaaga-ziibi''. Watershed The Nottawasaga River's h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Toronto Press
The University of Toronto Press is a Canadian university press founded in 1901. Although it was founded in 1901, the press did not actually publish any books until 1911. The press originally printed only examination books and the university calendar. Its first scholarly book was a work by a classics professor at University College, Toronto. The press took control of the university bookstore in 1933. It employed a novel typesetting method to print issues of the ''Canadian Journal of Mathematics'', founded in 1949. Sidney Earle Smith, president of the University of Toronto in the late 1940s and 1950s, instituted a new governance arrangement for the press modelled on the governing structure of the university as a whole (on the standard Canadian university governance model defined by the Flavelle commission). Henceforth, the press's business affairs and editorial decision-making would be governed by separate committees, the latter by academic faculty. A committee composed of Vincent ...

Jefferson Salamander
The Jefferson salamander (''Ambystoma jeffersonianum'') is a mole salamander native to the northeastern United States, southern and central Ontario, and southwestern Quebec. It was named after Jefferson College in Pennsylvania. It is typically dark gray, brown, or black on its dorsal surface, but a lighter shade on its anterior. Some individuals may also have silver or blue specks on their sides; the area around the vent is usually gray. These salamanders are slender, with a wide nose and distinctive long toes, and range in size from . Like other mole salamanders, the Jefferson salamander burrows; they have well-developed lungs suited for this purpose. Nocturnal by nature, they can be spotted by day during the mating season. Breeding occurs in early spring, after the snow in the area has melted. Reproduction Eggs are laid in small agglomerations attached to submerged twigs or other natural support at the pond's edge. Clutches can contain between 5 and 60 eggs, averaging about 3 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northern Brook Lamprey
The northern brook lamprey (''Ichthyomyzon fossor'') is a freshwater fish in the family Petromyzontidae. It is closely related to the silver lamprey (''I. unicuspis'') and may represent an ecotype of a single species with ''I. unicuspis''. Description Northern brook lampreys are jawless fishes, also known as cyclostomes. Northern brook lamprey are considered non-parasitic lamprey. They have poorly developed teeth and a round, disc-like, subterminal mouth, called an oral-disc, for suction. Northern brook lampreys have a single dorsal fin that continues along their entire length until it connects with the caudal fin. This dorsal fin can be notched as well. Their coloration is gray-brown dorsally with a light line down the back and an even lighter ventral side. The length of adult northern brook lampreys does not typically exceed 16 cm and the body is attenuate. While the ammocoetes look similar to the adult lampreys the ammocoetes have a hooded mouth instead of an oral-disc an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Louisiana Waterthrush
The Louisiana waterthrush (''Parkesia motacilla'') is a New World warbler, that breeds in eastern North America and winters in the West Indies and Central America. Plain brown above, it is white below, with black streaks and with buff flanks and undertail, distinguishing it from the closely related northern waterthrush. The habitats it prefers are streams and their surroundings, and other wet areas. Range It breeds in eastern North America from southernmost Canada and south through the eastern United States, excluding Florida and the coast. The Louisiana waterthrush is bird migration, migratory, wintering in Central America and the West Indies. This is a rare vagrant to the western United States. They are one of the earlier neotropical migrants to return to their breeding grounds in the spring, often completing their migration in late March or early April, which is almost two months before most other warblers reach their breeding grounds. They are also one of the earliest warblers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northern Long-eared Myotis
''Myotis septentrionalis'', known as the northern long-eared bat or northern myotis, is a species of bat native to North America. There are no recognized subspecies. The northern long-eared bat is about 3–3.7 inches in length, with a wingspan of 9–10 inches. It is distinguishable by its long ears when comparing it to other bats in its genus. This species is commonly found in the northern United States and Southern Canada east of British Columbia. The geographic range includes 37 states. Description The northern long-eared bat is a small bat, measuring an average of in total length, including a tail about long. Adults weigh between . The fur and wing membranes are light brown in color, and the bat lacks the dark shoulder spots found in the closely related, and otherwise similar Keen's myotis (''Myotis keenii''). Compared to other ''Myotis'' species, these bats have long ears with a relatively long, pointed tragus; when folded forwards the ears extend well past the nose. The ...

Butternut Canker
''Ophiognomonia clavigignenti-juglandacearum'' is a mitosporic fungus that causes the lethal disease of butternut trees (''Juglans cinerea''), butternut canker. It is also known to parasitize other members of the genus ''Juglans'' on occasion, and very rarely other related trees including hickories. The fungus is found throughout North America, occurring on up to 91% of butternut trees, and may be threatening the viability of butternut as a species. Distribution Butternut, the primary host of ''S. clavigignenti-juglandacearum'', is found in mixed hardwood forests throughout central North America, from New Brunswick to North Carolina. The pathogen was identified as an invasive species in 1967. It was first discovered in Wisconsin, but has since spread to other states and into Canada, making the Butternut an endangered species in Ontario. Its native origin is unknown, but possibly in Asia given the resistance of Asian walnuts to the disease. The United States Forest Service fo ...

Juglans Cinerea
''Juglans cinerea'', commonly known as butternut or white walnut,Snow, Charles Henry ''The Principal Species of Wood: Their Characteristic Properties'' 2nd ed. New York: John Wiley & Sons, 1908. p. 56. is a species of walnut native to the eastern United States and southeast Canada. Distribution The distribution range of ''J. cinerea'' extends east to New Brunswick, and from southern Quebec west to Minnesota, south to northern Alabama and southwest to northern Arkansas. It is absent from most of the Southern United States. The species also proliferates at middle elevations (about above sea level) in the Columbia River basin, Pacific Northwest; as an off-site species. Trees with (over mature) class range diameter at breast height were noted in the Imnaha River drainage as late as January 26, 2015. Butternut favors a cooler climate than black walnut and its range does not extend into the Deep South. Its northern range extends into Wisconsin and Minnesota where the growing s ...

Sand Violet
''Viola adunca'' is a species of violet known by the common names hookedspur violet, early blue violet, sand violet, and western dog violet. It is native to meadows and forests of western North America, Canada, and the northern contiguous United States. Description This is a hairy, compact plant growing from a small rhizome system. The leaves are spade- or heart-shaped, sometimes with broadly wavy margins. They are generally 0.5 to 4 centimeters long. The single-flowered inflorescence grows at the end of a very thin peduncle reaching about high. The nodding flower is a violet about long, with five purple petals. The lower three petals have white bases and purple veining. The two side petals are white-bearded near the throat. The upper two petals may have hooked spurs at their tips. It is a perennial blooming in late spring. There are several varieties of ''V. adunca''; a white-petaled form has been noted in Yosemite National Park. It has also been observed in Southern Ontar ...

Cuckoo Flower
''Cardamine pratensis'', the cuckoo flower, lady's smock, mayflower, or milkmaids, is a flowering plant in the family Brassicaceae. It is a perennial herb native throughout most of Europe and Western Asia. The specific name ''pratensis'' is Latin for "meadow". Description ''Cardamine pratensis'' is a herbaceous, hairless,Webb, D.A., Parnell, J. and Doogue, D. ''An Irish Flora'' 1996. Dundalgan Press, Dundalk. perennial plant growing to 40–60 cm tall, with pinnate leaves 5–12 cm long with 3–15 leaflets, each leaflet about 1 cm long. The flowers are produced on a spike 10–30 cm long, each flower 1–2 cm in diameter with four very pale violet-pink (rarely white) petals. The style of the fruit is short or longish. It grows best close to water. Etymology Its common name ''cuckoo flower'' derives from the formation of the plant's flowers at around the same time as the arrival each spring of the first cuckoos in the British Isles.

Vascular Plant
Vascular plants (), also called tracheophytes () or collectively Tracheophyta (), form a large group of land plants ( accepted known species) that have lignified tissues (the xylem) for conducting water and minerals throughout the plant. They also have a specialized non-lignified tissue (the phloem) to conduct products of photosynthesis. Vascular plants include the clubmosses, horsetails, ferns, gymnosperms (including conifers), and angiosperms (flowering plants). Scientific names for the group include Tracheophyta, Tracheobionta and Equisetopsida ''sensu lato''. Some early land plants (the rhyniophytes) had less developed vascular tissue; the term eutracheophyte has been used for all other vascular plants, including all living ones. Historically, vascular plants were known as "higher plants", as it was believed that they were further evolved than other plants due to being more complex organisms. However, this is an antiquated remnant of the obsolete scala naturae, and the term ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Queenston Shale
The Queenston Formation is a geological formation of Upper Ordovician age (Maysvillian to Richmondian Stage), which outcrops in Ontario, Canada (along the northern and eastern flanks of the Niagara Escarpment, as well as east of Ottawa) and New York, United States (just south of Lake Ontario). A typical outcrop of the formation is exposed at Bronte Creek just south of the Queen Elizabeth Way. The formation is a part of the Queenston Delta clastic wedge, formed as an erosional response to the Taconic Orogeny. Lithologically, the formation is dominated by red and grey shales with thin siltstone, limestone and sandstone interlayers. As materials, comprising the clastic wedge, become coarser in close proximity to the Taconic source rocks, siltstone and sandstone layers are predominant in New York. Structure and stratigraphy The formation is wedge-shaped, thick (up to below Lake Erie), and laterally extensive, outcropping from Western New York to Cabot Head. It thins from southeast ...
