95-535: Nuns' Island (officially Île-des-Sœurs ; French pronunciation: [il de sœʁ] ) is an island located in the Saint Lawrence River that forms a part of the city of Montreal , Quebec . It is part of the borough of Verdun . Originally called Île Saint-Paul in honour of the founder of Montreal, Paul de Chomedey, Sieur de Maisonneuve , the island was initially acquired in 1634 by Jean de Lauzon , future governor of New France. The island
190-578: A continent by plate tectonics , and oceanic islands, which have never been part of a continent. Oceanic islands can be formed from volcanic activity, grow into atolls from coral reefs , and form from sediment along shorelines, creating barrier islands . River islands can also form from sediment and debris in rivers. Artificial islands are those made by humans, including small rocky outcroppings built out of lagoons and large-scale land reclamation projects used for development. Islands are host to diverse plant and animal life. Oceanic islands have

The presence of an island is marked by seabirds , differences in cloud and weather patterns, as well as changes in the direction of waves. It is also possible for human populations to have gone extinct on islands, evidenced by explorers finding islands that show evidence of habitation but no life. Not all islands were or are inhabited by maritime cultures. In
380-514: A "rafting event". This phenomenon is known as oceanic dispersal . Tropical storms have the capacity to transport species over great distances. Animals like tortoises can live for weeks without food or water, and are able to survive floating on debris in the sea. One case study showed that in 1995, fifteen iguanas survived a 300 km journey to Anguilla in the Caribbean , an island which no iguana had lived on previously. They survived floating on

Because of the virtually impassable Lachine Rapids , the St. Lawrence was once continuously navigable only as far as Montreal. Opened in 1825, the Lachine Canal was the first to allow ships to pass the rapids. An extensive system of canals and locks, known as the St. Lawrence Seaway , was officially opened on 26 June 1959 by Elizabeth II (representing Canada) and President Dwight D. Eisenhower (representing
570-426: A detailed review of 1,288 islands found that they were home to 1,189 highly-threatened vertebrate species, which was 41 percent of the global figure. Coral bleaching is expected to occur with more frequency, threatening marine ecosystems, some of which island economies are dependent on. Some islands that are low-lying may cease to exist given high enough amounts of sea level rise. Tuvalu received media attention for

Permanent river islands also exist, the largest of which (that is completely inland) is Bananal Island in the Tocantins of Brazil, which has a maximum width of 55 kilometers. Lakes form for a variety of reasons, including glaciers , plate tectonics, and volcanism. Lake islands can form as part of these processes. The field of insular biogeography studies

Oceanic islands, ones that have never been connected to shore, are only populated by life that can cross the sea. This means that any animals present on the island had to have flown there, in the case of birds or bats , were carried by such animals, or were carried in a sea current in what is known as
1045-477: A loss of almost all the infrastructure in Dominica. Sea level rise and other climate changes can reduce freshwater reserves, resulting in droughts . These risks are expected to decrease the habitability of islands, especially small ones. Beyond risks to human life, plant and animal life are threatened. It has been estimated that almost 50 percent of land species threatened by extinction live on islands. In 2017,

New Zealand and Australia share 200 native plant species, despite being separated by 1500 km. Continental islands, islands that were at one point connected to a continent, are expected to share a common history of plant and animal life up until the point that the island broke away from
1235-837: A minimum. Some islands became host to humans due to a land bridge or a continental island splitting from the mainland. Today, up to 10% of the world's population lives on islands. Islands are popular targets for tourism due to their perceived natural beauty, isolation, and unique cultures. Islands became the target of colonization by Europeans, resulting in the majority of islands in the Pacific being put under European control. Decolonization has resulted in some but not all island nations becoming self-governing , with lasting effects related to industrialisation , invasive species , nuclear weapons testing , and tourism . Islands and island countries are threatened by climate change . Sea level rise threatens to submerge nations such as Maldives ,
1330-743: A minority. Cultural attitudes related to communal ownership of land as well as a lack of individualistic decision-making may make some island cultures less compatible with the global capitalist economy, causing these nations to experience less economic growth. Islands have long been a popular target for tourism , thanks to their unique climates, cultures, and natural beauty. However, islands may suffer from poor transportation connectivity from airplanes and boats and strains on infrastructure from tourist activity. Islands in colder climates often rely on seasonal tourists seeking to enjoy nature or local cultures, and may only be one aspect of an island's economy. In contrast, tourism on tropical islands can often make up

The campus consists of a cluster of five low-rise buildings, located at the Autoroute 10 and 15 highway interchange at the northerly end of the island. A substantial part of Nuns' Island is leased by Structures Metropolitaines from the current landowners of the Island. the Place du Commerce shopping centre. The Décarie South Expressway (Autoroute 15) runs through Nuns' Island, connecting it to
1520-613: A permanent caisson , a steel or concrete structure built in a closed loop and then filled with sand. Some modern islands have been constructed by pouring millions of tons of sand into the sea, such as with Pearl Island in Qatar or the Palm Islands in Dubai. These islands are usually created for real estate development , and are sold for private ownership or construction of housing. Offshore oil platforms have also been described as
1615-524: A phenomenon where new oceanic crust is formed, pushing away older crust. Islands sitting on the continental shelf may be called continental islands. Other islands, like those that make up New Zealand , are what remains of continents that shrank and sunk beneath the sea. It was estimated that Zealandia , the continent-like area of crust that New Zealand sits on, has had 93% of its original surface area submerged. Some islands are formed when coral reefs grow on volcanic islands that have submerged beneath
1710-423: A press conference publicizing the ongoing submerging of the island country. Tuvalu signed a cooperation agreement with Australia agreeing to annually allow 280 of its citizens to become permanent residents of Australia. The Marshall Islands, a country of 1,156 islands, have also been identified as a country that may be existentially threatened by rising seas. Increasing intensity of tropical storms also increases
1805-483: A priority target of conservation efforts, to prevent the extinction of these species. Despite high levels of endemism, the total species richness , the total number of unique species in a region, is lower on islands than on mainlands. The level of species richness on islands is proportional to the area of that island, a phenomenon known as the species-area relationship . This is because larger areas have more resources and thus can support more organisms. Populations with

The natural beauty of island nations also makes them a magnet for tourism . Islands also have geopolitical value for naval bases , weapons testing , and general territorial control. One such example is French Polynesia ,

The river's present name has been used since 1604 when it was recorded on a map by Samuel de Champlain Champlain opted for the names Grande riviere de sainct Laurens and Fleuve sainct Laurens in his writings, supplanting the earlier names. In contemporary French, the name is rendered as the fleuve Saint-Laurent . The name Saint-Laurent (Saint Lawrence)

#17327805055642090-476: A selection pressure for smaller animals that require less food. Having fewer predators would mean these animals did not need not be large to survive. Charles Darwin formulated the theory of natural selection through the study of island ecology. The species he observed on the Galápagos Islands , including tanager birds, contributed to his understanding of how evolution works. He first traveled to
2185-509: A specific property known as adaptive radiation . In this process, a species that arrives on a group of islands rapidly becomes more diverse over time, splitting off into new species or subspecies. A species that reaches an island ecosystem may face little competition for resources, or may find that the resources that they found in their previous habitat are not available. These factors together result in individual evolutionary branches with different means of survival. The classical example of this
2280-414: A territory that receives substantial military expenditure and aid from France. Since the first discoveries of Polynesian, Micronesian , and other islands by Westerners, these nations have been the subject of colonization. Islands were the target of Christian missionaries . These missionaries faced resistance, but found success when some local chiefs used European support to centralize power. Beginning in

A possible explanation for this phenomenon is that these landmasses were once all part of the continent Gondwana and separated by tectonic drift. However, there are competing theories that suggest this species may have reached faraway places by way of oceanic dispersal. Species that colonize island archipelagos exhibit
2470-616: A type of island. Some atolls have been covered in concrete to create artificial islands for military purposes, such as those created by China in the South China Sea . These atolls were previously low-tide elevations, landmasses that are only above water during low tide . The United Nations Convention on the Law of the Sea indicates that these islands may not have the same legal status as a naturally occurring island, and as such may not confer
2565-515: Is Darwin's finches , a group of up to fifteen tanager species that are endemic to the Galápagos Islands. These birds evolved different beaks in order to eat different kinds of food available on the islands. The large ground finch has a large bill used to crack seeds and eat fruit. The Genovesa cactus finch prefers cacti as a food source, and has a beak adapted for removing pulp and flowers from cacti. The green warbler-finch (in

Larger animals such as the hippopotamus tend to become smaller, such as in the case of the pygmy hippopotamus . This is known as insular dwarfism . In the case of smaller animals, it has been hypothesized that animals on islands may have fewer predators and competitors, resulting in selection pressure towards larger animals. Larger animals may exhaust food resources quickly due to their size, causing malnutrition in their young, resulting in

3800-507: The Polynesians . Many of the previous island settlements required traveling distances of less than 100 km (62 mi), whereas Polynesians may have traveled 2,000–3,200 km (1,200–2,000 mi) to settle islands such as Tahiti . They would send navigators to sail the ocean without the aid of navigational instruments to discover new islands for settlement. Between 1100 and 800 BC, Polynesians sailed East from New Guinea and

The furthest extent of this migration would be Easter Island in the East, and New Zealand in the South, with New Zealand's first settlements between 1250 and 1300. Historians have sought to understand why some remote islands have always been uninhabited, while others, especially in the Pacific Ocean , have long been populated by humans. Generally, larger islands are more likely to be able to sustain humans and thus are more likely to have been settled. Small islands that cannot sustain populations on their own can still be habitable if they are within

3990-499: The Solomon Islands created eighty such islands by piling coral and rock in the Lau Lagoon . One traditional way of constructing islands is with the use of a revetment . Sandbags or stones are dropped with a barge into the sea to bring the land level slightly out of the water. The island area is then filled with sand or gravel, followed by a construction of this revetment to hold it together. Islands have also been constructed with

Reaching the Indonesian islands of Flores and Timor would have required crossing distances of water of at least 29 km (18 mi). Some islands, such as Honshu , were probably connected to the mainland with a land bridge that allowed humans to colonize it before it became an island. The first people to colonize distant oceanic islands were

Others compare the motivations of Polynesian and similar explorers with those of Christopher Columbus , the explorer who sailed westward over
7125-490: The major rivers that flow into the Great Lakes. Great Lakes tributaries are listed in alphabetical order. The list includes all tributaries with a drainage area of at least 1,000 square kilometres and an average flow of more than 10 cubic metres per second. tributary The diversity of the St. Lawrence River includes: Large marine mammals travel in all the seas of the earth, the research and observations of these giants concern fishermen and shipping industry , exercise
7220-589: The majority of the local economy and built environment . These islands sometimes also require consistent foreign aid on top of tourism in order to ensure economic growth. This reliance can result in social inequality and environmental degradation . During tourism downturns, these economies struggle to make up the lost inflow of cash with other industries. Climate change threatens human development on islands due to sea level rise , more dangerous tropical cyclones , coral bleaching , and an increase in invasive species . For example, in 2017 Hurricane Maria caused
7315-624: The north and south shores of the river, overlapping with Nitassinan and the more western Wabanaki or Dawnland countries. Adjacent on the north shore is the Atikamekw territorial homeland of Nitaskinan and, upstream, the further reaches of Anishinaabewaki, specifically the homelands of the Algonquin and Mississauga Nations. The Norse explored the Gulf of St. Lawrence in the 11th century and were followed by fifteenth- and early sixteenth-century European mariners, such as John Cabot , and
7410-535: The northern end was mapped as Ste-Philomène sandy loam. The island is noted for its parks and scenery including West Vancouver Park which overlooks the Saint Lawrence River . The 64 acre (26-hectare) Domaine Saint-Paul natural woodland in the southern part of the island, a crucial nesting area for more than a hundred species of birds, is one of the last remaining natural woodlands in southern Montreal. It has been progressively eroded by development. The woodland surrounds an artificial lake called Lac des Battures. This lake
7505-529: The past, some societies were found to have lost their seafaring ability over time, such as the case of the Canary Islands , which were occupied by an indigenous people since the island's first discovery in the first century until being conquered by the Spanish Empire in 1496. It has been hypothesized that since the inhabitants had little incentive for trade and had little to any contact with
7600-514: The river and estuary include the 1,864 river islands of the Thousand Islands , the endangered whales of Saguenay–St. Lawrence Marine Park , and the limestone monoliths of the Mingan Archipelago . Long a transportation route to Indigenous peoples , the St. Lawrence River has played a key role in the history of Canada and in the development of cities such as Montreal and Quebec City . The river remains an important shipping route as
7695-800: The river borders Mi'kma'ki in the South (what is today known as the Canadian Maritimes ), and Nitassinan in the North, the national territory of the Innu people . On the south shore beyond the Mi'kmaw district of Gespe'gewa'ki , the river passes Wolastokuk (the Maliseet homeland), Pαnawαhpskewahki (the Penobscot homeland), and Ndakinna (the Abenaki homeland). Continuing, the river passes through
7790-545: The same legal rights. Saint Lawrence River The St. Lawrence River ( French : Fleuve Saint-Laurent ) is a large international river in the middle latitudes of North America connecting the Great Lakes to the North Atlantic Ocean . Its waters flow in a northeasterly direction from Lake Ontario to the Gulf of St. Lawrence , traversing Ontario and Quebec in Canada and New York in
7885-789: The sea entirely. An example is the Hawaiian Islands , with the oldest island being 25 million years old, and the youngest, Hawaii , still being an active volcano . However, not all island chains are formed this way. Some may be formed all at once by fractures in the tectonic plates themselves, simultaneously creating multiple islands. One supporting piece of evidence is that of the Line Islands , which are all estimated to be 8 million years old, rather than being different ages. Other island chains form due to being separated from existing continents. The Japanese archipelago may have been separated from Eurasia due to seafloor spreading ,
7980-653: The south bank of the St. Lawrence River via the Champlain Bridge and to the Island of Montreal via the Pont de l'Île-des-Sœurs, part of the Champlain Bridge complex. The Clément Bridge connects the island with the Bonaventure Expressway (Aut. 10) . There are only two schools on the island, École primaire Île-des-Sœurs and École des Marguerite. The primary schools are both part of Montreal's French-language Marguerite-Bourgeoys School Board . In July 2023, Île-des-Sœurs station opened. The rapid transit station
8075-549: The study of islands is due to their unique cultures and natural environments that differ from mainland cultures. This is for a few reasons: First, the obvious political and geographic isolation from mainland cultures. Second, unique restraints on resources and ecology creating marine-focused cultures with a focus on fishing and sailing. Third, a lasting historical and political significance of islands. The Polynesian diet got most of its protein from fishing. Polynesians were known to fish close to shore, as well as in deep water. It
8170-450: The surface. When these coral islands encircle a central lagoon , the island is known as an atoll . The formation of reefs and islands related to those reefs is aided by the buildup of sediment in shallow patches of water. In some cases, tectonic movements lifting a reef out of the water by as little as 1 meter can cause sediment to accumulate and an island to form. Barrier islands are long, sandy bars that form along shorelines due to
8265-438: The time of Charles Darwin . In biology, endemism is defined as the phenomenon where species or genus is only found in a certain geographical area. Islands isolate land organisms from others with water, and isolate aquatic organisms living on them with land. Island ecosystems have the highest rates of endemism globally. This means that islands contribute heavily to global biodiversity . Areas with high lives of biodiversity are
8360-458: The water system frequently changes its name. From source to mouth, the names are: The St. Lawrence River also passes through Lake Saint-Louis and Lake Saint-Pierre in Quebec. The St. Lawrence River and the largest tributaries of the Great Lakes . The St. Lawrence River tributaries are listed upstream from the mouth. The major tributaries of the inter-lake sections are also shown, as well as
8455-440: Was actually created by accident as parts of the river known as "water lots" became landlocked during landfill operations in the 1960s and 1970s. Most of this landfill came from the excavation of Montreal's underground Metro system in the mid-1960s. That part of the Island was subject to annual floods caused by spring runoff. The resulting dykes and fill allowed an additional few million square feet to be used for development as well as
8550-526: Was built and operated by John Molson and associates, a scant two years after Fulton's steam-powered navigation of the Hudson River . The Accommodation with ten passengers made her maiden voyage from Montreal to Quebec City in 66 hours, for 30 of which she was at anchor. She had a keel of 75 feet, and a length overall of 85 feet. The cost of a ticket was eight dollars upstream, and nine dollars down. She had berths that year for twenty passengers. Within
8645-399: Was completed the following year, notably including four buildings by Ludwig Mies van der Rohe : three high rise apartment buildings, the first of which, 201 rue Corot, was occupied in 1969, and an Esso filling station of the same vintage. By the mid-1970s, significant areas to the south of the island were reclaimed from the St. Lawrence and eclectic constructions sprung in various parts of
8740-410: Was continuously shrinking during that time, a process that continues today. The head of the St. Lawrence River, near Lake Ontario, is home to the Thousand Islands . Today, the St. Lawrence River begins at the outflow of Lake Ontario and flows adjacent to Gananoque , Brockville , Morristown , Ogdensburg , Massena , Cornwall , Montreal , Trois-Rivières , and Quebec City before draining into
8835-438: Was included in the expansive seigneurie of La Citière on the south shore of the St. Lawrence. In 1664 he ceded the island in three equal parts to three prominent citizens of Ville-Marie : Jacques Le Ber , sieur de Saint-Paul et Senneville; Claude Robutel de Saint-André , sieur de La Noue; and Jean de la Vigne, who transferred his portion to Jacques Le Ber's sister Marie in 1668. She, in turn, sold her share to her brother, leaving
8930-463: Was originally applied to the eponymous bay by Jacques Cartier upon his arrival into the region on the 10th of August feast day for Saint Lawrence in 1535. Indigenous people use the following names: In winter, the St. Lawrence River begins producing ice in December, with the formation of ice cubes between Montreal and Quebec City . The prevailing winds and currents push this ice towards
9025-470: Was reported that Rapa Nui people were known to fish as far as 500 km (310 mi) from shore at coral reefs. Spear , line , and net fishing were all used, to catch tuna as well as sharks and stingrays . Island cultures also cultivate native and non-native crops. Polynesians grew the native yam , taro , breadfruit , banana , coconut and other fruits and vegetables. Different island climates made different resources more important, such as
