Round Lake National Natural Landmark
Round Lake National Natural Landmark lies within Green Lakes State Park, which lies a few miles east of the city of Syracuse, New York and adjoining the village of Fayetteville, New York, Fayetteville. Round Lake itself and the adjoining of old-growth forest were designated a National Natural Landmark in 1973 by the United States Department of the Interior, U.S. Department of the Interior. Hubert W. Vogelmann, a professor of botany at the University of Vermont, wrote the evaluation to the National Park Service that concurred with the recommendation of National Natural Landmark status for the region around Round Lake. Vogelmann's evaluation noted the "outstanding virgin mesophyte, mesophytic forest" adjoining Round Lake on its southwestern side; this text became part of the citation when the landmark was created. Vogelmann also noted Round Lake's importance as an extremely rare, "meromictic" lake. It shares this distinction with Green Lake (New York), Green Lake, which lies a few hun ...

Green Lake (New York)
Green Lake is the larger of the two lakes in Green Lakes State Park, which lies about east of downtown Syracuse in Onondaga County, New York. Round Lake is the smaller lake located west of Green Lake. Both lakes are meromictic, which means no seasonal mixing of surface and bottom waters occurs. Meromictic lakes are fairly rare; they have been extensively studied, in part because their sediments can preserve a historical record extending back thousands of years, and because of the euxinic (anoxic, sulfidic) conditions which can form in the deep water. Description Green Lake has a maximum depth of 195 feet (59 metres). Deep lakes tend to appear bluish because the wavelengths of light that can penetrate (and be dispersed at) great depths are those closer to the blue end of the spectrum. Because of its depth and the high salinity of the basin waters, the lake is meromictic and does not turn over and intermix waters like many other lakes in this region do. Green Lake's cold and dens ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Central New York Military Tract
The Military Tract of Central New York, also called the New Military Tract, consisted of nearly of bounty land set aside in Central New York to compensate New York's soldiers after their participation in the Revolutionary War. Establishment The Province of New York (predecessor of the U.S. state) had already guaranteed each soldier at least at the end of the war (depending on rank), but by 1781, New York had enlisted only about half of the quota set by the U.S. Congress and needed a stronger incentive. The legislature authorized an additional per soldier, using land from 25 Military Tract Townships to be established in central New York State. Each of the townships was to comprise 100 lots of each. Three more such townships, Junius, Galen, and Sterling, were later added to accommodate additional claims at the end of the war. The United States Congress approved in 1789, and the arrangement became final in 1799. Townships The townships were at first numbered (1 through 28), b ...

Precipitate
In an aqueous solution, precipitation is the process of transforming a dissolved substance into an insoluble solid from a super-saturated solution. The solid formed is called the precipitate. In case of an inorganic chemical reaction leading to precipitation, the chemical reagent causing the solid to form is called the ''precipitant''. The clear liquid remaining above the precipitated or the centrifuged solid phase is also called the 'supernate' or 'supernatant'. The notion of precipitation can also be extended to other domains of chemistry (organic chemistry and biochemistry) and even be applied to the solid phases (''e.g.'', metallurgy and alloys) when solid impurities segregate from a solid phase. Supersaturation The precipitation of a compound may occur when its concentration exceeds its solubility. This can be due to temperature changes, solvent evaporation, or by mixing solvents. Precipitation occurs more rapidly from a strongly supersaturated solution. The formati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limnology
Limnology ( ; from Greek λίμνη, ''limne'', "lake" and λόγος, ''logos'', "knowledge") is the study of inland aquatic ecosystems. The study of limnology includes aspects of the biological, chemical, physical, and geological characteristics of fresh and saline, natural and man-made bodies of water. This includes the study of lakes, reservoirs, ponds, rivers, springs, streams, wetlands, and groundwater.Wetzel, R.G. 2001. Limnology: Lake and River Ecosystems, 3rd ed. Academic Press () Water systems are often categorized as either running (lotic) or standing (lentic). Limnology includes the study of the drainage basin, movement of water through the basin and biogeochemical changes that occur en route. A more recent sub-discipline of limnology, termed landscape limnology, studies, manages, and seeks to conserve these ecosystems using a landscape perspective, by explicitly examining connections between an aquatic ecosystem and its drainage basin. Recently, the need to u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thuja Occidentalis
''Thuja occidentalis'', also known as northern white-cedar, eastern white-cedar, or arborvitae, is an evergreen coniferous tree, in the cypress family Cupressaceae, which is native to eastern Canada and much of the north-central and northeastern United States. It is widely cultivated as an ornamental plant. Common names Its additional common names include swamp cedar, American arborvitae, and eastern arborvitae. The name arborvitae is particularly used in the horticultural trade in the United States; it is Latin for 'tree of life' – due to the supposed medicinal properties of the sap, bark, and twigs.''Thuja'', American Cancer Society, last revised 6/19/2007available online/ref> It is sometimes called white-cedar (hyphenated) or whitecedar (one word) to distinguish it from ''Cedrus'', a distantly related genus of trees also known as cedars. Description Unlike the closely related western red cedar (''Thuja plicata''), northern white cedar is only a small or medium-sized tre ...

Tilia Americana
''Tilia americana'' is a species of tree in the family Malvaceae, native to eastern North America, from southeast Manitoba east to New Brunswick, southwest to northeast Oklahoma, southeast to South Carolina, and west along the Niobrara River to Cherry County, Nebraska. It is the sole representative of its genus in the Western Hemisphere, assuming ''T. caroliniana'' is treated as a subspecies or local ecotype of ''T. americana''. Common names include American basswood and American linden. Description The American basswood is a medium-sized to large deciduous tree reaching a height of exceptionally with a trunk diameter of at maturity. It grows faster than many North American hardwoods, often twice the annual growth rate of American beech and many birch species. Life expectancy is around 200 years, with flowering and seeding generally occurring between 15 and 100 years, though occasionally seed production may start as early as eight years. The crown is domed, the branches s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fagus Grandifolia
''Fagus grandifolia'', the American beech or North American beech, is a species of beech tree native to the eastern United States and extreme southeast of Canada. Description ''Fagus grandifolia'' is a large deciduous tree growing to tall, with smooth, silver-gray bark. The leaves are dark green, simple and sparsely-toothed with small teeth that terminate each vein, long (rarely ), with a short petiole. The winter twigs are distinctive among North American trees, being long and slender ( by ) with two rows of overlapping scales on the buds. Beech buds are distinctly thin and long, resembling cigars; this characteristic makes beech trees relatively easy to identify. The tree is monoecious, with flowers of both sexes on the same tree. The fruit is a small, sharply-angled nut, borne in pairs in a soft-spined, four-lobed husk. It has two means of reproduction: one is through the usual dispersal of seedlings, and the other is through root sprouts, which grow into new trees. ...

Acer Saccharum
''Acer saccharum'', the sugar maple, is a species of flowering plant in the soapberry and lychee family Sapindaceae. It is native to the hardwood forests of eastern Canada and eastern United States. Sugar maple is best known for being the primary source of maple syrup and for its brightly colored fall foliage. It may also be known as "rock maple", "sugar tree", "birds-eye maple", "sweet maple", "curly maple", or "hard maple", particularly when referring to the wood. Description ''Acer saccharum'' is a deciduous tree normally reaching heights of , and exceptionally up to . A 10-year-old tree is typically about tall. As with most trees, forest-grown sugar maples form a much taller trunk and narrower canopy than open-growth ones. The leaves are deciduous, up to long and wide, palmate, with five lobes and borne in opposite pairs. The basal lobes are relatively small, while the upper lobes are larger and deeply notched. In contrast with the angular notching of the silver ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Liriodendron Tulipifera
''Liriodendron tulipifera''—known as the tulip tree, American tulip tree, tulipwood, tuliptree, tulip poplar, whitewood, fiddletree, and yellow-poplar—is the North American representative of the two-species genus '' Liriodendron'' (the other member is '' Liriodendron chinense''), and the tallest eastern hardwood. It is native to eastern North America from Southern Ontario and possibly southern Quebec to Illinois eastward to southwestern Massachusetts and Rhode Island, and south to central Florida and Louisiana. It can grow to more than in virgin cove forests of the Appalachian Mountains, often with no limbs until it reaches in height, making it a very valuable timber tree. The tallest individual at the present time (2021) is one called the Fork Ridge Tulip Tree at a secret location in the Great Smoky Mountains of North Carolina. Repeated measurements by laser and tape-drop have shown it to be in height. This is the tallest known individual tree in eastern North Americ ...

Tsuga
''Tsuga'' (, from Japanese (), the name of ''Tsuga sieboldii'') is a genus of conifers in the subfamily Abietoideae of Pinaceae, the pine family. The common name hemlock is derived from a perceived similarity in the smell of its crushed foliage to that of the unrelated plant poison hemlock. Unlike the latter, ''Tsuga'' species are not poisonous. The genus comprises eight to ten species (depending on the authority), with four species occurring in North America and four to six in eastern Asia. Description They are medium-sized to large evergreen trees, ranging from tall, with a conical to irregular crown, the latter occurring especially in some of the Asian species. The leading shoots generally droop. The bark is scaly and commonly deeply furrowed, with the colour ranging from grey to brown. The branches stem horizontally from the trunk and are usually arranged in flattened sprays that bend downward towards their tips. Short spur shoots, which are present in many gymnosperm ...

Old-growth
An old-growth forestalso termed primary forest, virgin forest, late seral forest, primeval forest, or first-growth forestis a forest that has attained great age without significant disturbance, and thereby exhibits unique ecological features, and might be classified as a climax community. The Food and Agriculture Organization of the United Nations defines primary forests as naturally regenerated forests of native tree species where there are no clearly visible indications of human activity and the ecological processes are not significantly disturbed. More than one-third (34 percent) of the world's forests are primary forests. Old-growth features include diverse tree-related structures that provide diverse wildlife habitat that increases the biodiversity of the forested ecosystem. Virgin or first-growth forests are old-growth forests that have never been logged. The concept of diverse tree structure includes multi-layered canopies and canopy gaps, greatly varying tree heights ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
