Burlington, Ontario
Burlington is a city in the Regional Municipality of Halton at the northwestern end of Lake Ontario in Ontario, Canada. Along with Milton to the north, it forms the western end of the Greater Toronto Area and is also part of the Hamilton metropolitan census area. History Before the 19th century, the area between the provincial capital of York and the township of West Flamborough was home to the Mississauga nation. In 1792, John Graves Simcoe, the first lieutenant governor of Upper Canada, named the western end of Lake Ontario "Burlington Bay" after the town of Bridlington in the East Riding of Yorkshire, England. The British purchased the land on which Burlington now stands from the Mississaugas in Upper Canada Treaties 3 (1792), 8 (1797), 14 (1806), and 19 (1818). Treaty 8 concerned the purchase of the Brant Tract, on Burlington Bay which the British granted to Mohawk chief Joseph Brant for his service in the American Revolutionary War. Joseph Brant and his household se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Community Ecology
In ecology, a community is a group or association of populations of two or more different species occupying the same geographical area at the same time, also known as a biocoenosis, biotic community, biological community, ecological community, or life assemblage. The term community has a variety of uses. In its simplest form it refers to groups of organisms in a specific place or time, for example, "the fish community of Lake Ontario before industrialization". Community ecology or synecology is the study of the interactions between species in communities on many spatial and temporal scales, including the distribution, structure, abundance, demography, and interactions between coexisting populations. The primary focus of community ecology is on the interactions between populations as determined by specific genotypic and phenotypic characteristics. Community ecology also takes into account abiotic factors that influence species distributions or interactions (e.g. annual temperat ...

Canadian Ecologists
Canadians (french: Canadiens) are people identified with the country of Canada. This connection may be residential, legal, historical or cultural. For most Canadians, many (or all) of these connections exist and are collectively the source of their being ''Canadian''. Canada is a multilingual and multicultural society home to people of groups of many different ethnic, religious, and national origins, with the majority of the population made up of Old World immigrants and their descendants. Following the initial period of French and then the much larger British colonization, different waves (or peaks) of immigration and settlement of non-indigenous peoples took place over the course of nearly two centuries and continue today. Elements of Indigenous, French, British, and more recent immigrant customs, languages, and religions have combined to form the culture of Canada, and thus a Canadian identity. Canada has also been strongly influenced by its linguistic, geographic, and ec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Carex Juniperorum
''Carex juniperorum'', the juniper sedge, is a perennial flowering plant native to North America, first described by botanist William J. Crins in 1993. ''C. juniperorum'' is in the ''Cyperaceae'' (sedge) family, and is closely related to '' C. jamesii'' and '' C. willdenowii''. It is commonly called juniper sedge as it is often seen growing in areas with red cedar (''Juniperus virginiana''), though the presence of cedar is not necessarily a requirement for it to grow. Distribution Juniper sedge is globally rare. It only occurs in sections of Ohio, Kentucky, and Virginia in the United States. In Canada, it is found in the province of Ontario. Description and habitat Juniper sedge prefers dry, open, calcareous soils that are periodically disturbed to maintain canopy cover. The plant grows forming a clump, with grass-like leaves up to 30cm long with a reddish-brown basal sheath. Flowers occur in early may on a small basal spike. Small (1.5-2mm) ellipsoid perigynia form in lat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hoverfly
Hover flies, also called flower flies or syrphid flies, make up the insect family Syrphidae. As their common name suggests, they are often seen hovering or nectaring at flowers; the adults of many species feed mainly on nectar and pollen, while the larvae (maggots) eat a wide range of foods. In some species, the larvae are saprotrophs, eating decaying plant and animal matter in the soil or in ponds and streams. In other species, the larvae are insectivores and prey on aphids, thrips, and other plant-sucking insects. Insects such as aphids are considered a crop pest, and therefore the aphid-eating larvae of some hover flies serve as an economically (as well as ecologically) important predator and even potential agents for use in biological control, while the adults may be pollinators. About 6,000 species in 200 genera have been described. Hover flies are common throughout the world and can be found on all continents except Antarctica. Hover flies are harmless to most mammals, ...

Protected Area
Protected areas or conservation areas are locations which receive protection because of their recognized natural, ecological or cultural values. There are several kinds of protected areas, which vary by level of protection depending on the enabling laws of each country or the regulations of the international organizations involved. Generally speaking though, protected areas are understood to be those in which human presence or at least the exploitation of natural resources (e.g. firewood, non-timber forest products, water, ...) is limited. The term "protected area" also includes marine protected areas, the boundaries of which will include some area of ocean, and transboundary protected areas that overlap multiple countries which remove the borders inside the area for conservation and economic purposes. There are over 161,000 protected areas in the world (as of October 2010) with more added daily, representing between 10 and 15 percent of the world's land surface area. As of 20 ...

Population Ecology
Population ecology is a sub-field of ecology that deals with the dynamics of species populations and how these populations interact with the environment, such as birth and death rates, and by immigration and emigration. The discipline is important in conservation biology, especially in the development of population viability analysis which makes it possible to predict the long-term probability of a species persisting in a given patch of habitat. Although population ecology is a subfield of biology, it provides interesting problems for mathematicians and statisticians who work in population dynamics. History In the 1940s ecology was divided into autecology—the study of individual species in relation to the environment—and synecology—the study of groups of species in relation to the environment. The term autecology (from Ancient Greek: αὐτο, ''aúto'', "self"; οίκος, ''oíkos'', "household"; and λόγος, ''lógos'', "knowledge"), refers to roughly the same fie ...
