Val-des-Monts, Quebec
Val-des-Monts is a municipality in the Outaouais region of Quebec, Canada, located about north of Ottawa, Ontario. It has a population of 13,328 residents in 2021. Formed in 1975 by the merger of the towns of Perkins, Saint-Pierre-de-Wakefield and Poltimore, it consists mainly of farms and mountainous forests. Many of its residents commute to Ottawa or Gatineau for work. Due to its numerous lakes, its population is boosted during summers by people living in cottages. Most of the people in Val-des-Monts live in the village of Perkins. Toponymy The name of Val-des-Monts is from the French words ''Val'' which means "small valley" and ''Monts'' which means "mounts". This name is a reference to the fact that the territory of the municipality includes several valleys and mountains.

Les Collines-de-l'Outaouais Regional County Municipality
Les Collines-de-l'Outaouais (French for "The hills of the Outaouais") is a regional county municipality in the Outaouais region of western Quebec, Canada. The region nearly encircles the City of Gatineau, which is to the south. Its administrative seat is in Chelsea, Quebec. It was created in January 1991 when the Communauté régionale de l'Outaouais (Outaouais Regional Community) was split into Les Collines-de-l'Outaouais RCM and the Communauté urbaine de l'Outaouais (Outaouais Urban Community, now City of Gatineau). The region is home to the majority of Gatineau Park. It is bisected by the Gatineau River which flows from north to south. The Ottawa River forms the southwestern boundary. Subdivisions There are six subdivisions within the RCM: ;Municipalities (6) * Cantley * Chelsea * L'Ange-Gardien * La Pêche * Pontiac * Val-des-Monts Demographics Transportation Access routes Highways and numbered routes that run through the municipality, including external routes that ...

Outaouais
Outaouais (, ; also commonly called The Outaouais) is a region of western Quebec, Canada. It includes the city of Gatineau, the municipality of Val-des-Monts and the Papineau region. Geographically, it is located on the north side of the Ottawa River opposite Canada's capital, Ottawa. It has a land area of and its population was 382,604 inhabitants as of the 2016 Census. History The name of the region comes from the French name for the Ottawa River, which in turn comes from the French name for the Indigenous Odawa that lived near the region. Prior to European arrival in the region, the areas along the Ottawa River were commonly used by various tribes to trade and gather. The oldest European settlement in the region is Hull (now a neighbourhood of Gatineau) which was founded in 1800 by Philemon Wright as Wright's Town. The settlement quickly became involved in the lumber trade, which continued along the Ottawa River until the late 20th century. None of the original town ...

Ottawa
Ottawa (, ; Canadian French: ) is the capital city of Canada. It is located at the confluence of the Ottawa River and the Rideau River in the southern portion of the province of Ontario. Ottawa borders Gatineau, Quebec, and forms the core of the Ottawa–Gatineau census metropolitan area (CMA) and the National Capital Region (NCR). Ottawa had a city population of 1,017,449 and a metropolitan population of 1,488,307, making it the fourth-largest city and fourth-largest metropolitan area in Canada. Ottawa is the political centre of Canada and headquarters to the federal government. The city houses numerous foreign embassies, key buildings, organizations, and institutions of Canada's government, including the Parliament of Canada, the Supreme Court, the residence of Canada's viceroy, and Office of the Prime Minister. Founded in 1826 as Bytown, and incorporated as Ottawa in 1855, its original boundaries were expanded through numerous annexations and were ultimately ...

Lac Grand (Quebec)
Lac Grand is a lake in the Outaouais region of Quebec, Canada. It covers an area of about 377 hectares and lies at an elevation of above sea level. There are no settlements on the lake, although it has many cottages on its shore. Despite having many cottages, some permanent residents live on the lake. Watersports such as waterskiing and sailing are popular among residents of the lake. Other popular recreation includes fishing and swimming. The lake community recently published a book for lake residents entitled "The Grand Experience", covering the history and geography of the lake. Geography The lake consists of four main bays, two in the south, two in the north. The main section of the lake is where it reaches its deepest depths, going as deep as 40 metres below the surface, which is slightly deeper than significantly larger Lake Winnipeg. There are many islands in Lac Grand, the largest being Ile-Des-Peres in Priest's Bay. Lac Grand has two inflows, including a stream and ...

Phosphorus
Phosphorus is a chemical element with the symbol P and atomic number 15. Elemental phosphorus exists in two major forms, white phosphorus and red phosphorus, but because it is highly reactive, phosphorus is never found as a free element on Earth. It has a concentration in the Earth's crust of about one gram per kilogram (compare copper at about 0.06 grams). In minerals, phosphorus generally occurs as phosphate. Elemental phosphorus was first isolated as white phosphorus in 1669. White phosphorus emits a faint glow when exposed to oxygen – hence the name, taken from Greek mythology, meaning 'light-bearer' (Latin ), referring to the " Morning Star", the planet Venus. The term '' phosphorescence'', meaning glow after illumination, derives from this property of phosphorus, although the word has since been used for a different physical process that produces a glow. The glow of phosphorus is caused by oxidation of the white (but not red) phosphorus — a process now called chem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oligotrophic
An oligotroph is an organism that can live in an environment that offers very low levels of nutrients. They may be contrasted with copiotrophs, which prefer nutritionally rich environments. Oligotrophs are characterized by slow growth, low rates of metabolism, and generally low population density. Oligotrophic environments are those that offer little to sustain life. These environments include deep oceanic sediments, caves, glacial and polar ice, deep subsurface soil, aquifers, ocean waters, and leached soils. Examples of oligotrophic organisms are the cave-dwelling olm; the bacterium " ''Candidatus'' Pelagibacter communis", which is the most abundant organism in the oceans with an estimated 2 × 1028 individuals in total; and the lichens with their extremely low metabolic rate. Etymologically, the word "oligotroph" is a combination of the Greek adjective ''oligos'' (ὀλίγος) meaning "few" and the adjective ''trophikos'' (τροφικός)) meaning "feeding". Plant adaptatio ...

Chlorophyll
Chlorophyll (also chlorophyl) is any of several related green pigments found in cyanobacteria and in the chloroplasts of algae and plants. Its name is derived from the Greek words , ("pale green") and , ("leaf"). Chlorophyll allow plants to absorb energy from light. Chlorophylls absorb light most strongly in the blue portion of the electromagnetic spectrum as well as the red portion. Conversely, it is a poor absorber of green and near-green portions of the spectrum. Hence chlorophyll-containing tissues appear green because green light, diffusively reflected by structures like cell walls, is less absorbed. Two types of chlorophyll exist in the photosystems of green plants: chlorophyll ''a'' and ''b''. History Chlorophyll was first isolated and named by Joseph Bienaimé Caventou and Pierre Joseph Pelletier in 1817. The presence of magnesium in chlorophyll was discovered in 1906, and was that element's first detection in living tissue. After initial work done by German chemi ...

Cyanobacteria
Cyanobacteria (), also known as Cyanophyta, are a phylum of gram-negative bacteria that obtain energy via photosynthesis. The name ''cyanobacteria'' refers to their color (), which similarly forms the basis of cyanobacteria's common name, blue-green algae, although they are not usually scientifically classified as algae. They appear to have originated in a freshwater or terrestrial environment. Sericytochromatia, the proposed name of the paraphyletic and most basal group, is the ancestor of both the non-photosynthetic group Melainabacteria and the photosynthetic cyanobacteria, also called Oxyphotobacteria. Cyanobacteria use photosynthetic pigments, such as carotenoids, phycobilins, and various forms of chlorophyll, which absorb energy from light. Unlike heterotrophic prokaryotes, cyanobacteria have internal membranes. These are flattened sacs called thylakoids where photosynthesis is performed. Phototrophic eukaryotes such as green plants perform photosynthesis in plast ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
