121-561: The grey seal ( Halichoerus grypus ) is a large seal of the family Phocidae , which are commonly referred to as "true seals" or "earless seals". The only species classified in the genus Halichoerus , it is found on both shores of the North Atlantic Ocean . In Latin , Halichoerus grypus means "hook-nosed sea pig". Its name is spelled gray seal in the United States ; it is also known as Atlantic seal and
242-592: A Maritime Union has been proposed at various times in Canada's history; the first discussions in 1864 at the Charlottetown Conference contributed to Canadian Confederation . This movement formed the larger Dominion of Canada . The Mi'kmaq , Maliseet and Passamaquoddy people are indigenous to the Maritimes, while Acadian and British settlements date to the 17th century. The word maritime
363-700: A monophyletic origin. A 2021 genetic study found that pinnipeds are more closely related to musteloids. Pinnipeds split from other caniforms 50 million years ago ( mya ) during the Eocene . The earliest fossils of pinnipeds date back to the Late Oligocene . Fossil animals representing basal lineages include Puijila , of the Early Miocene in Arctic Canada. It resembled a modern otter, but shows evidence of quadrupedal swimming—retaining
484-616: A monophyletic group (descended from one ancestor). Pinnipeds belong to the suborder Caniformia of the order Carnivora ; their closest living relatives are musteloids ( weasels , raccoons , skunks and red pandas ), having diverged about 50 million years ago. Seals range in size from the 1 m (3 ft 3 in) and 45 kg (100 lb) Baikal seal to the 5 m (16 ft) and 3,200 kg (7,100 lb) southern elephant seal . Several species exhibit sexual dimorphism . They have streamlined bodies and four limbs that are modified into flippers . Though not as fast in
605-482: A Golden Age, but that was a myth created in the 1930s to lure tourists to a romantic era of tall ships and antiques. Recent historians using census data have shown that is a fallacy. In 1851–1871 there was an overall increase in per capita wealth holding. However most of the gains went to the urban elite class, especially businessmen and financiers living in Halifax. The wealth held by the top 10% rose considerably over
726-687: A booming agricultural and fishing export economy having led to that colony opting not to sign on. The major communities of the region include Halifax and Cape Breton in Nova Scotia, Moncton , Saint John , and Fredericton in New Brunswick, and Charlottetown in Prince Edward Island. In spite of its name, The Maritimes has a humid continental climate of the warm-summer subtype. Especially in coastal Nova Scotia, differences between summers and winters are narrow compared to
847-615: A few, such as the leopard seal , feed on large vertebrates, such as penguins and other seals. Walruses are specialized for feeding on bottom-dwelling mollusks . Male pinnipeds typically mate with more than one female ( polygyny ), though the degree of polygyny varies with the species. The males of land-breeding species tend to mate with a greater number of females than those of ice breeding species . Male pinniped strategies for reproductive success vary between defending females, defending territories that attract females and performing ritual displays or lek mating . Pups are typically born in
968-506: A form of aquatic locomotion that led to those employed by modern pinnipeds. Potamotherium , which lived in the same period in Europe, was similar to Puijila but more aquatic. The braincase of Potamotherium shows evidence that it used its whiskers to hunt, like modern seals. Both Puijila and Potamotherium fossils have been found in lake deposits, suggesting that seal ancestors were originally adapted for fresh water. Enaliarctos ,
1089-419: A fossil species of late Oligocene /early Miocene (24–22 mya) California , closely resembled modern pinnipeds; it was adapted to an aquatic life with flippers and a flexible spine. Its teeth were more like land predators in that they were more adapted for shearing . Its hind-flippers may have allowed it to walk on land, and it probably did not leave coastal areas as much as its modern relatives. Enaliarctos
1210-670: A great many potential culprits. In 1867 Nova Scotia and New Brunswick merged with the Canadas in Confederation , with Prince Edward Island joining them six years later in 1873. Canada was formed only a year after free trade with the United States (in the form of the Reciprocity Treaty ) had ended. In the 1870s John A. Macdonald 's National Policy was implemented, creating a system of protective tariffs around
1331-586: A layer of fat, or blubber , under the skin to keep warm in cold water, and, other than the walrus, all species are covered in fur. Although pinnipeds are widespread, most species prefer the colder waters of the Northern and Southern Hemispheres. They spend most of their lives in water, but come ashore to mate, give birth, molt or to avoid ocean predators, such as sharks and orcas . Seals mainly live in marine environments but can also be found in fresh water. They feed largely on fish and marine invertebrates ;

#17327913180931452-660: A less curved profile than harbor seal bulls. Males are generally darker than females, with lighter patches and often scarring around the neck. Females are silver grey to brown with dark patches. In the United Kingdom and Ireland , the grey seal breeds in several colonies on and around the coasts. Notably large colonies are at Blakeney Point in Norfolk , Donna Nook in Lincolnshire , the Farne Islands off
1573-516: A male grey seal in the North Sea was documented and filmed killing and cannibalising 11 pups of his own species over the course of a week. Similar wounds on the carcasses of pups found elsewhere in the region suggest that cannibalism and infanticide may not be uncommon in grey seals. Male grey seals may engage in such behaviour potentially as a way of increasing reproductive success through access to easy prey without leaving prime territory. While it
1694-612: A portion of coastal Maine at one point. The most significant incident from this war which occurred in the Maritimes was the British capture and detention of USS Chesapeake , an American frigate in Halifax. In 1820, the Colony of Cape Breton Island was merged back into the Colony of Nova Scotia for the second time by the British government. British settlement of the Maritimes, as the colonies of Nova Scotia, New Brunswick and Prince Edward Island came to be known, accelerated throughout
1815-416: A similar view and provides considerable evidence that the early 1880s were in fact a booming period in Nova Scotia and this growth was only undermined towards the end of that decade. David Alexander argues that any earlier declines were simply part of the global Long Depression , and that the Maritimes first fell behind the rest of Canada when the great boom period of the early 20th century had little effect on
1936-444: A single pup every year, with females' reproductive years beginning as early as 4 years old and extending up to 30 years of age. All parental care is provided by the female. During breeding, males do not provide parental care but they defend females against other males for mating. The pups are born at around the mass of 14 kg. They are born in autumn (September to December) in the eastern Atlantic and in winter (January to February) in
2057-611: A smaller population of the Maliseet in western New Brunswick. Given the small population of the region (compared with the Central Canadian provinces or the New England states), the regional economy is a net exporter of natural resources, manufactured goods, and services. The regional economy has long been tied to natural resources such as fishing, logging, farming, and mining activities. Significant industrialization in
2178-513: A surprise, but the clapping we know typically occurs in captivity. Clapping seals are associated with aquariums and zoos, but were never observed in the wild for this behavior. They were astonished at how loud these marine mammals were able to clap underwater, but it is logical for the reasons they do this. Grey seals are capital breeders; they forage to build up stored blubber, which is utilised when they are breeding and weaning their pups, as they do not forage for food at this time. They give birth to
2299-636: A telltale sign of attack by a Greenland shark (also called the sleeper shark). In the waters of Great Britain , grey seals are a fairly common prey species for killer whales . Apparently, grey seal pups are sometimes taken from beach colonies by white-tailed eagles , and golden eagles , as well. The grey seal feeds on a wide variety of fish , mostly benthic or demersal species, taken at depths down to 70 m (230 ft) or more. Sand eels ( Ammodytes spp ) are important in its diet in many localities. Cod and other gadids , flatfish , herring , wrasse and skates are also important locally. However, it
2420-668: A weight of as much as 400 kg (880 lb) and females averaging up to 2.05 m (6 ft 9 in) and sometimes weighing up to 250 kg (550 lb). Record-sized bull grey seals can reach about 3.3 m (10 ft 10 in) in length. A common average weight in Great Britain was found to be about 233 kg (514 lb) for males and 154.6 kg (341 lb) for females whereas in Nova Scotia , Canada , adult males averaged 294.6 kg (649 lb) and adult females averaged 224.5 kg (495 lb). It
2541-520: A widely distributed and diverse clade of carnivorous , fin -footed, semiaquatic , mostly marine mammals . They comprise the extant families Odobenidae (whose only living member is the walrus ), Otariidae (the eared seals: sea lions and fur seals ), and Phocidae (the earless seals, or true seals), with 34 extant species and more than 50 extinct species described from fossils . While seals were historically thought to have descended from two ancestral lines, molecular evidence supports them as

#17327913180932662-488: Is a fairly large seal, with bulls in the eastern Atlantic populations reaching 1.95–2.3 m (6 ft 5 in – 7 ft 7 in) long and weighing 170–310 kg (370–680 lb); the cows are much smaller, typically 1.6–1.95 m (5 ft 3 in – 6 ft 5 in) long and 100–190 kg (220–420 lb) in weight. Individuals from the western Atlantic are often much larger, with males averaging up to 2.7 m (8 ft 10 in) and reaching
2783-532: Is a report by Farley Mowat of historic breeding colonies as far south as Cape Hatteras , North Carolina. An isolated population exists in the Baltic Sea , forming the H. grypus balticus subspecies. Besides these very large colonies, many much smaller ones exist, some of which are well-known tourist attractions, despite their small size. Such colonies include one on the Carrack rocks , Cornwall . During
2904-536: Is an adjective that means of the sea ; from Latin maritimus "of the sea, near the sea", from mare "sea". Thus any land adjacent to the sea can be considered maritime. But the term Maritimes has historically been collectively applied to New Brunswick, Nova Scotia and Prince Edward Island, all of which border the Atlantic Ocean . The pre-history of the Canadian Maritimes begins after
3025-402: Is because of their massive ankle bones and flatter heels. In water, true seals rely on the side-to-side motion of their hind-flippers and lower body to move forward. The phocid's skull has thickened mastoids , puffed up entotympanic bones , nasal bones with a pointed tip in the back and a non-existent supraorbital foramen. The hip has a more converse ilium . A 2006 molecular study supports
3146-548: Is called the Laurentian tradition started among Archaic Indians , the term used for First Nations peoples of the time. Evidence of Archaic Indian burial mounds and other ceremonial sites existing in the Saint John River valley has been uncovered. The Late Period extended from 3,000 years ago until first contact with European settlers. This period was dominated by the organization of First Nations peoples into
3267-449: Is clear that the grey seal will eat whatever is available, including octopus and lobsters . The average daily food requirement is estimated to be 5 kg (11 lb), though the seal does not feed every day and it fasts during the breeding season. Recent observations and studies from Scotland, The Netherlands, and Germany show that grey seals will also prey and feed on large animals like harbour seals and harbour porpoises . In 2014,
3388-450: Is distinguished from the smaller harbor seal by its straight head profile, nostrils set well apart, and fewer spots on its body. Wintering hooded seals can be confused with grey seals as they are about the same size and somewhat share a large-nosed look but the hooded has a paler base colour and usually evidences a stronger spotting. Grey seals lack external ear flaps and characteristically have large snouts. Bull greys have larger noses and
3509-702: Is less prevalent today. During the American Civil War , a significant number of Maritimers volunteered to fight for the armies of the Union , while a small handful joined the Confederate Army . However, the majority of the conflict's impact was felt in the shipping industry. Maritime shipping boomed during the war due to large-scale Northern imports of war supplies which were often carried by Maritime ships as Union ships were vulnerable to Confederate naval raiders. Diplomatic tensions between Britain and
3630-631: The Algonquian -speaking Abenaki Nation, which occupied territory largely in present-day interior Vermont , New Hampshire , and Maine , and the Mi'kmaq Nation, which inhabited all of Nova Scotia, Prince Edward Island, eastern New Brunswick and the southern Gaspé . The primarily agrarian Maliseet Nation settled throughout the Saint John River and Allagash River valleys of present-day New Brunswick and Maine. The Passamaquoddy Nation inhabited
3751-593: The Annapolis Basin . Acadians lived with uncertainty throughout the English constitutional crises under Oliver Cromwell , and it was not until the Treaty of Breda in 1667 that France's claim to the region was reaffirmed. Colonial administration by France throughout the history of Acadia was of low priority. France's priorities were in settling and strengthening its claim on the larger territory of New France and

3872-746: The Baltic Sea increased about 8% per year between 1990 and the mid-2000s, with the numbers becoming stagnant since 2005. As of 2011, hunting grey seals is legal in Sweden and Finland , with 50% of the quota being used. Other anthropogenic causes of death include drowning in fishing gear. Grey seals have proved amenable to life in captivity and are commonly found in zoo animals around their native range, particularly in Europe. Traditionally they were popular circus animals and often used in performances such as balancing and display acts. [REDACTED] Pinniped Pinnipeds (pronounced / ˈ p ɪ n ɪ ˌ p ɛ d z / ), commonly known as seals , are

The Acadians eventually built small settlements throughout what is today mainland Nova Scotia and New Brunswick , as well as Île-Saint-Jean ( Prince Edward Island ), Île-Royale ( Cape Breton Island ), and other shorelines of the Gulf of St. Lawrence in present-day Newfoundland and Labrador , and Quebec . Acadian settlements had primarily agrarian economies. Early examples of Acadian fishing settlements developed in southwestern Nova Scotia and in Île-Royale, as well as along
4114-565: The Brittany , Normandie , and Vienne regions of France, continued to populate the colony of Acadia during the latter part of the 17th and early part of the 18th centuries. Important settlements also began in the Beaubassin region of the present-day Isthmus of Chignecto , and in the Saint John River valley, as well as smaller communities on Île-Saint-Jean and Île-Royale. In 1654, raiders from New England attacked Acadian settlements on

Coincident with the construction of railways in the region, the age of the wooden sailing ship began to come to an end, being replaced by larger and faster steel steamships . The Maritimes had long been a centre for shipbuilding , and this industry was hurt by the change. The larger ships were also less likely to call on
4356-689: The Caribbean monk seal have become extinct in the past century, while the Mediterranean monk seal and Hawaiian monk seal are ranked as endangered by the International Union for Conservation of Nature . Besides hunting, pinnipeds also face threats from accidental trapping , marine pollution , climate change and conflicts with local people. The name "pinniped" derives from the Latin words pinna ' fin ' and pes, pedis ' foot ' . The common name "seal" originates from

There are two recognized subspecies of this seal: The type specimen of H. g. grypus ( Zoological Museum of Copenhagen specimen ZMUC M11-1525, caught in 1788 off the island of Amager , Danish part of the Baltic Sea ) was believed lost for many years but was rediscovered in 2016, and a DNA test showed it belonged to a Baltic Sea specimen rather than from Greenland, as had previously been assumed (because it
5566-662: The nasal bones , with a large and flattened supraorbital foramen . An extra spine splits the supraspinatous fossa and bronchi that are divided in the front. Otariids consist of two types: sea lions and fur seals ; the latter typically being smaller, with pointier snouts, longer fore-flippers and heavier fur coats . Five genera and seven species (one now extinct) of sea lion are known to exist, while two genera and nine species of fur seal exist. While sea lions and fur seals have historically been considered separate subfamilies (Otariinae and Arctocephalinae respectively), genetic and molecular evidence has refuted this, indicating that
5687-550: The northern fur seal is basal to other otariids and the Australian sea lion and New Zealand sea lion are more closely related to Arctocephalus than to other sea lions. Odobenidae has only one living member: the walrus . This animal is noticeable from its larger size (exceeded only by the elephant seals ), nearly hairless skin, flattened snout and long upper canines , known as tusks . Like otariids, walruses can walk on land with their hind limbs. When moving in water,
5808-551: The orbital wall . The extinct family Desmatophocidae lived 23–10 mya in the North Pacific. They had long skulls that with large orbits, interlocked zygomatic bones and rounded molars and premolars . They also were sexually dimorphic and may have been capable of swimming with both or either pair of flippers. They are grouped with modern pinnipeds, but there is debate as to whether they are more closely related to phocids or to otariids and walruses. The ancestors of

Several species have male-biased sexual dimorphism that depends on how polygynous a species is: highly polygynous species like elephant seals are extremely sexually dimorphic, while less polygynous species have males and females that are closer in size, or, in
6050-531: The 17th and 18th centuries brought Acadia to the centre of world-scale geopolitical forces. In 1613, Virginian raiders captured Port-Royal, and in 1621 France ceded Acadia to Scotland's Sir William Alexander , who renamed it Nova Scotia . By 1632, Acadia was returned from Scotland to France under the Treaty of Saint-Germain-en-Laye . The Port Royale settlement was moved to the site of nearby present-day Annapolis Royal . More French immigrant settlers, primarily from

Since the 1990s the region has experienced an exceptionally tumultuous period in its regional economy with the collapse of large portions of the ground fishery throughout Atlantic Canada, the closing of coal mines and a steel mill on Cape Breton Island , and the closure of military bases in all three provinces. That being said, New Brunswick has one of

The British sought to neutralize any military threat Acadians posed and to interrupt the vital supply lines Acadians provided to Louisbourg by deporting Acadians from Acadia. The British began the Expulsion of the Acadians with the Bay of Fundy campaign in 1775. Over the next nine years over 12,000 Acadians of 15,000 were removed from Nova Scotia. In 1758,

At the same time, another part of the Colony of Nova Scotia, Cape Breton Island, was split off to become the Colony of Cape Breton Island. The Colony of St. John's Island was renamed Prince Edward Island on November 29, 1798. The War of 1812 had some effect on the shipping industry in the Maritime colonies of New Brunswick, Nova Scotia, Prince Edward Island, and Cape Breton Island; however,

Located along the Atlantic coast, various aquatic sub-basins are located in the Maritimes, such as the Gulf of Maine and Gulf of St. Lawrence . The region is located northeast of New England in the United States, south and southeast of Quebec 's Gaspé Peninsula , and southwest of the island of Newfoundland . The notion of

However, it was French explorer Jacques Cartier who made the first detailed reconnaissance of the region for a European power and, in so doing, claimed the region for the King of France. Cartier was followed by nobleman Pierre Dugua, Sieur de Mons , who was accompanied by explorer / cartographer Samuel de Champlain in a 1604 expedition. During this they established
7018-411: The Maritimes. Growth was strong, and the region had one of British North America 's most extensive manufacturing sectors as well as a large international shipping industry. The question of why the Maritimes fell from being a centre of Canadian manufacturing to being an economic hinterland is thus a central one to the study of the region's pecuniary difficulties. The period in which the decline occurred had

The lineages of Otariidae and Odobenidae split around 20 mya. The earliest fossil records of otariids are in North Pacific and dated to around 11 mya. Early fossil genera include Pithanotaria and Thalassoleon . The Callorhinus lineage split

Phocids are known to have existed for at least 15 million years, and molecular evidence supports a divergence of the Monachinae and Phocinae lineages around this time. The fossil genera Monotherium and Leptophoca of southeastern North America represent the earliest members of Monachinae and Phocinae respectively. Both lineages may have originated in

One year after Congress passed the 1972 Marine Mammal Protection Act preventing the harming or harassing of seals, a survey of the entire Maine coast found only 30 grey seals. At first grey seal populations increased slowly but then rebounded from islands off Maine to Monomoy Island and Nantucket Island off of southern Cape Cod . The southernmost breeding colony
7623-455: The body. Seals are unique among carnivorans in that their orbital walls are mostly shaped by the maxilla and are not contained by certain facial bones. Compared to land carnivores, pinnipeds have fewer teeth, which are pointed and cone-shaped. They are adapted for holding onto slippery prey rather than shearing meat like the carnassials of other carnivorans. The walrus has unique tusks which are long upper canines. Pinnipeds range in size from

Males of sexually dimorphic species also tend to have secondary sex characteristics , such as larger or more prominent heads, necks, chests, crests , noses/ proboscises and canine teeth as well as thicker fur and manes. Though more polygynous species tend to be sexually dimorphic, some evidence suggests that size differences between

Historian Kris Inwood places the date very early, at least in Nova Scotia, finding clear signs that the Maritimes "Golden Age" of the mid-19th century was over by 1870, before Confederation or the National Policy could have had any significant impact. Richard Caves places the date closer to 1885. T.W. Acheson takes

One popular hypothesis suggested that pinnipeds are diphyletic (descended from two ancestral lines), with walruses and otariids sharing a recent common ancestor with bears ; and phocids sharing one with Musteloidea . However, morphological and molecular evidence support

The Charlottetown Conference ended with an agreement to meet the following month in Quebec City , where more formal discussions ensued, culminating with meetings in London and the signing of the British North America Act , 1867 (BNA Act). Of the Maritime provinces, only Nova Scotia and New Brunswick were initially party to the BNA Act: Prince Edward Island's reluctance, combined with
8712-450: The era was indeed a golden age but only for a small but powerful and highly visible elite. The cause of economic malaise in the Maritimes is an issue of great debate and controversy among historians, economists, and geographers. The differing opinions can approximately be divided into the "structuralists", who argue that poor policy decisions are to blame, and the others, who argue that unavoidable technological and geographical factors caused
8833-532: The exploration and settlement of interior North America and the Mississippi River valley. Over 74 years (1689–1763) there were six colonial wars, which involved continuous warfare between New England and Acadia (see the French and Indian Wars reflecting English and French tensions in Europe, as well as Father Rale's War (Dummer's War) and Father Le Loutre's War ). Throughout these wars, New England
8954-431: The first commercial production field for oil beginning in the 1980s. Natural gas was also discovered in the 1980s during exploration work, and this is being commercially recovered, beginning in the late 1990s. Initial optimism in Nova Scotia about the potential of off-shore resources appears to have diminished with the lack of new discoveries, although exploration work continues and is moving farther off-shore into waters on
9075-430: The fortress of Louisbourg was laid siege for a second time within 15 years, this time by more than 27,000 British soldiers and sailors with over 150 warships. After the French surrender, Louisbourg was thoroughly destroyed by British engineers to ensure it would never be reclaimed. With the fall of Louisbourg, French and Mi'kmaw resistance in the region crumbled. British forces seized remaining French control over Acadia in
9196-461: The largest military bases in the Commonwealth of Nations ( CFB Gagetown ), which plays a significant role in the cultural and economic spheres of Fredericton, the province's capital city. While the economic underperformance of the Maritime economy has been long lasting, it has not always been present. The mid-19th century, especially the 1850s and 1860s, has long been seen as a "Golden Age" in
9317-646: The late 18th century and into the 19th century with significant immigration to the region as a result of Scottish migrants displaced by the Highland Clearances and Irish escaping the Great Irish Famine (1845–1849). As a result, significant portions of the three provinces are influenced by Celtic heritages, with Scottish Gaelic (and to a lesser degree, Irish Gaelic ) having been widely spoken, particularly in Cape Breton, although it
9438-437: The more successful English settlement at Jamestown in present-day Virginia by three years. Champlain was considered the founder of New France 's province of Canada, which comprises much of the present-day lower St. Lawrence River valley in the province of Quebec . Champlain's success in the region, which came to be called Acadie , led to the fertile tidal marshes surrounding the southeastern and northeastern reaches of
9559-553: The most important changes, and one that almost certainly had an effect, was the revolution in transportation that occurred at this time. The Maritimes were connected to central Canada by the Intercolonial Railway in the 1870s, removing a longstanding barrier to trade. For the first time this placed the Maritime manufacturers in direct competition with those of Central Canada. Maritime trading patterns shifted considerably from mainly trading with New England , Britain, and
9680-425: The new nation. Throughout the period there was also significant technological change both in the production and transportation of goods. Several scholars have explored the so-called "Golden Age" of the Maritimes in the years just before Confederation. In Nova Scotia , the population grew steadily from 277,000 in 1851 to 388,000 in 1871, mostly from natural increase since immigration was slight. The era has been called
9801-527: The northerly retreat of glaciers at the end of the Wisconsin glaciation over 10,000 years ago; human settlement by First Nations began in the Maritimes with Paleo-Indians during the Early Period , ending around 6,000 years ago. The Middle Period , starting 6,000 years ago, and ending 3,000 years ago, was dominated by rising sea levels from the melting glaciers in polar regions. This is when what
9922-503: The northwestern coastal regions of the present-day Bay of Fundy . The Mi'kmaq Nation is also believed to have crossed the present-day Cabot Strait at around this time to settle on the south coast of Newfoundland , but they were a minority compared to the Beothuk Nation. After Newfoundland, the Maritimes were the second area in Canada to be settled by Europeans. There is evidence that Viking explorers discovered and settled in
10043-529: The other two Maritime provinces in that it has a much higher Francophone population . There was once a significant Canadian Gaelic speaking population. Helen Creighton recorded Celtic traditions of rural Nova Scotia in the mid-1900s. There are Black Canadians who are mostly descendants of Black Loyalists or black refugees from the War of 1812 . This Maritime population is mainly among Black Nova Scotians . There are Mi'kmaq reserves in all three provinces, and
10164-511: The potential negative effect of human noise has been highlighted with the discovery of seals using clapping as a form of communication. In the UK seals are protected under the Conservation of Seals Act 1970 ; however, it does not apply to Northern Ireland . In the UK there have also been calls for a cull from some fishermen claiming that stocks have declined due to the seals. The population in
10285-622: The region as the Home Office favoured newer colonial endeavours in Africa and elsewhere, led to a call among Maritime politicians for a conference on Maritime Union , to be held in early September 1864 in Charlottetown – chosen in part because of Prince Edward Island's reluctance to give up its jurisdictional sovereignty in favour of uniting with New Brunswick and Nova Scotia into a single colony. New Brunswick and Nova Scotia felt that if
10406-524: The region's finances. T.W. Acheson is one of the main proponents of this theory. He notes the growth that was occurring during the early years of the National Policy in Nova Scotia demonstrates how the effects of railway fares and the tariff structure helped undermine this growth. Capitalists from Central Canada purchased the factories and industries of the Maritimes from their bankrupt local owners and proceeded to close down many of them, consolidating
10527-424: The region's numerous universities and colleges—are significant economic contributors. Another important contribution to Nova Scotia's provincial economy is through spin-offs and royalties relating to off-shore petroleum exploration and development. Mostly concentrated on the continental shelf of the province's Atlantic coast in the vicinity of Sable Island , exploration activities began in the 1960s and resulted in
10648-405: The region. Another problem is seen in the lower average wages and family incomes within the region. Property values are depressed, resulting in a smaller tax base for these three provinces, particularly when compared with the national average which benefits from central and western Canadian economic growth. This has been particularly problematic with the growth of the welfare state in Canada since
10769-757: The region. E.R. Forbes, however, emphasizes that the precipitous decline did not occur until after the First World War during the 1920s when new railway policies were implemented. Forbes also contends that significant Canadian defence spending during the Second World War favoured powerful political interests in Central Canada such as C. D. Howe , when major Maritime shipyards and factories, as well as Canada's largest steel mill, located in Cape Breton Island, fared poorly. One of
10890-897: The rest of Canada. The inland climate of New Brunswick is in stark contrast during winter, resembling more continental areas. Summers are somewhat tempered by the marine influence throughout the provinces, but due to the southerly parallels still remain similar to more continental areas further west. Yarmouth in Nova Scotia has significant marine influence to have a borderline oceanic microclimate , but winter nights are still cold even in all coastal areas. The northernmost areas of New Brunswick are only just above subarctic with very cold continental winters. The Maritimes were predominantly rural until recent decades, having resource-based economies of fishing, agriculture, forestry, and coal mining. Maritimers are predominantly of west European origin: Scottish Canadians , Irish Canadians , English Canadians , and Acadians . New Brunswick, in general, differs from
11011-475: The sea to learn to fish for themselves. In recent years, the number of grey seals has been on the rise in the west and the U.S. and Canada there have been calls for a seal cull. Seal pup first-year survival rates are estimated to vary from 80–85% to below 50% depending on location and conditions. Starvation, due to difficulties in learning to feed, appears to be the main cause of pup death. After near extirpation from hunting grey seals for oil, meat, and skins in
11132-592: The seals. A count of 15,756 grey seals in southeastern Massachusetts coastal waters was made in 2011 by the National Marine Fisheries Service . Grey seals are being seen increasingly in New York and New Jersey waters, and it is expected that they will establish colonies further south. Human noise pollution continues to affect marine-life communication but remains an understudied facet of marine conservation efforts. In more recent years,
11253-410: The second half of the 19th century brought steel to Trenton, Nova Scotia , and subsequent creation of a widespread industrial base to take advantage of the region's large underground coal deposits. After Confederation, however, this industrial base withered with technological change, and trading links to Europe and the U.S. were reduced in favour of those with Ontario and Quebec. In recent years, however,
11374-489: The second permanent European settlement in what is now the United States and Canada, following Spain's settlement at St. Augustine in present-day Florida in the American South. Champlain's settlement at Saint Croix Island , later moved to Port Royal ( Annapolis Royal ), survived. By contrast, the ill-fated English settlement at Roanoke Colony off the southern American coast did not. The French settlement pre-dated
11495-527: The sexes originated due to ecological differences, with polygyny developing later. Maritime Provinces The Maritimes , also called the Maritime provinces , is a region of Eastern Canada consisting of three provinces : New Brunswick , Nova Scotia , and Prince Edward Island . The Maritimes had a population of 1,899,324 in 2021, which makes up 5.1% of Canada's population. Together with Canada's easternmost province, Newfoundland and Labrador ,
11616-464: The significant Royal Navy presence in Halifax and other ports in the region prevented any serious attempts by American raiders. Maritime and American privateers targeted unprotected shipping of both the United States and Britain respectively, further reducing trade. New Brunswick's section of the Canada–US border did not have any significant action during this conflict, although British forces did occupy
11737-469: The sixth and final colonial war, the French and Indian War (the North American theatre of the Seven Years' War ), the military conflicts in Nova Scotia continued. The British Conquest of Acadia happened in 1710. Over the next forty-five years, the Acadians refused to sign an unconditional oath of allegiance to Britain. During this time period Acadians participated in various militia operations against
11858-473: The smaller population centres such as Saint John and Halifax, preferring to travel to cities like New York and Montreal . Even the Cunard Line , founded by Maritime-born Samuel Cunard , stopped making more than a single ceremonial voyage to Halifax each year. More controversial than the role of technology is the argument over the role of politics in the origins of the region's decline. Confederation and
11979-618: The south and west coasts of Newfoundland, the Gaspé Peninsula , and the present-day Côte-Nord region of Quebec. Most Acadian fishing activities were overshadowed by the much larger seasonal European fishing fleets that were based out of Newfoundland and took advantage of proximity to the Grand Banks . The growing English colonies along the American seaboard to the south and various European wars between England and France during
12100-429: The spring and summer months and females bear almost all the responsibility for raising them. Mothers of some species fast and nurse their young for a relatively short period of time while others take foraging trips at sea between nursing bouts. Walruses are known to nurse their young while at sea. Seals produce a number of vocalizations , notably the barks of California sea lions , the gong -like calls of walruses and
12221-406: The superfamily Phocoidea. There are 34 extant species of pinnipeds, and more than 50 fossil species of pinnipedimorphs. Otariids are also known as eared seals due to their pinnae . These animals swim mainly using their well-developed fore-flippers. They can also "walk" on land by shifting their hind-flippers forward under the body. The front end of an otariid's frontal bone protrudes between
12342-466: The targets of American raiders. Charlottetown, the capital of the new colony of St. John's Island, was ransacked in 1775 with the provincial secretary kidnapped and the Great Seal stolen. The largest military action in the Maritimes during the revolutionary war was the attack on Fort Cumberland (the renamed Fort Beauséjour ) in 1776 by a force of American sympathizers led by Jonathan Eddy . The fort
12463-492: The tariff and railway freight policies that followed have often been blamed for having a deleterious effect on the Maritime economies. Arguments have been made that the Maritimes' poverty was caused by control over policy by Central Canada which used the national structures for its own enrichment. This was the central view of the Maritime Rights Movement of the 1920s, which advocated greater local control over
12584-489: The two decades, but there was little improvement in the wealth levels in rural areas, which comprised the great majority of the population. Likewise Gwyn reports that gentlemen, merchants, bankers, colliery owners, shipowners, shipbuilders, and master mariners flourished. However the great majority of families were headed by farmers, fishermen, craftsmen and labourer. Most of them—and many widows as well—lived in poverty. Out migration became an increasingly necessary option. Thus
12705-514: The union conference were held in Charlottetown, they might be able to convince Island politicians to support the proposal. The Charlottetown Conference , as it came to be called, was also attended by a slew of visiting delegates from the neighbouring Crown colony , the Province of Canada , who had largely arrived at their own invitation with their own agenda. This agenda saw the conference dominated by discussions of creating an even larger union of
12826-507: The upper Saint John River valley of New Brunswick. Some predominantly coastal areas have become major tourist centres, such as parts of Prince Edward Island, Cape Breton Island, the South Shore of Nova Scotia and the Gulf of St. Lawrence and Bay of Fundy coasts of New Brunswick. Additional service-related industries in information technology , pharmaceuticals, insurance and financial sectors—as well as research-related spin-offs from
12947-815: The upper and lower jaw. The familiar long upper tusks developed in the genera Valenictus and Odobenus . The lineage of the modern walrus may have spread from the North Pacific to the North Atlantic through the Caribbean and Central American Seaway 8–5 mya, and then back to the North Pacific via the Arctic 1 mya, or to the Arctic and subsequently the North Atlantic during the Pleistocene . Pinnipeds have streamlined, spindle-shaped bodies with small or non-existent ear flaps, rounded heads, short muzzles, flexible necks, limbs modified into flippers and small tails. The mammary glands and genitals can withdraw into
13068-445: The walrus relies on its hind limbs for locomotion, while its forelimbs are used for steering. Also, it has no outer ears. The epipterygoid of the jaw is well developed and the back of the nasal bones are horizontal. In the feet, the calcaneuses protrude in the middle. Phocids are known as true or "earless" seals. These animals lack outer ears and cannot position their hind-flippers to move on land, making them more cumbersome. This
13189-704: The water as dolphins , seals are more flexible and agile. Otariids primarily use their front limbs to propel themselves through the water, while phocids and walruses primarily use their hind limbs for this purpose. Otariids and walruses have hind limbs that can be pulled under the body and used as legs on land. By comparison, terrestrial locomotion by phocids is more cumbersome. Otariids have visible external ears, while phocids and walruses lack these. Pinnipeds have well-developed senses—their eyesight and hearing are adapted for both air and water, and they have an advanced tactile system in their whiskers or vibrissae. Some species are well adapted for diving to great depths. They have
13310-524: The waters around Connecticut , New York and Rhode Island . Archaeological evidence confirms grey seals in southern New England with remains found on Block Island , Martha's Vineyard , and near the mouth of the Quinnipiac River in New Haven, Connecticut . Its natural range now extends much further south than previously thought, with confirmed sightings off of North Carolina . Also, there
13431-438: The west, with a dense, soft silky white fur; at first small, they rapidly fatten up on their mothers' extremely fat-rich milk. The milk can consist of up to 60% fat. Grey seal pups are precocial, with mothers returning to the sea to forage once pups are weaned. Pups also undergo a post-weaning fast before leaving the land and learning to swim. Within a month or so they shed the pup fur, grow dense waterproof adult fur, and leave for
13552-750: The winter months, grey seals can be seen hauled out on rocks, islands, and shoals not far from shore, occasionally coming ashore to rest. In the spring, recently-weaned pups and yearlings occasionally strand on beaches after becoming separated from their group. Grey seals are vulnerable to typical predators for a pinniped mammal; their primary predator would be the orca or killer whale, but certain large species of sharks are known to prey on grey seals in North American waters, particularly great white sharks and bull sharks but also, upon evidence, additionally Greenland sharks . Some grey seal carcasses have washed ashore with visible “cookie cutter” bite marks,
13673-534: The world. In 1989, Annalisa Berta and colleagues proposed the unranked clade Pinnipedimorpha to contain the fossil genus Enaliarctos and modern seals as a sister group . Pinnipeds belong to the order Carnivora and the suborder Caniformia (known as dog-like carnivorans). Of the three extant families, the Otariidae and Odobenidae are grouped in the superfamily Otarioidea, while the Phocidae belong to
13794-799: Was allied with the Iroquois Confederacy based around the southern Great Lakes and west of the Hudson River . Acadian settlers were allied with the Wabanaki Confederacy . In the first war, King William's War (the North American theatre of the Nine Years' War ), natives from the Maritime region participated in numerous attacks with the French on the Acadia / New England border in southern Maine (e.g., Raid on Salmon Falls ). New England retaliatory raids on Acadia, such as
13915-403: Was established on Muskeget Island with five pups born in 1988 and over 2,000 counted in 2008. According to a genetics study, the United States population has formed as a result of recolonisation by Canadian seals. By 2009, thousands of grey seals had taken up residence on or near popular swimming beaches on outer Cape Cod, resulting in sightings of great white sharks drawn close to shore to hunt
14036-777: Was first described in Otto Fabricius ' book on the animals in Greenland: Fauna Groenlandica ). The name H. g. grypus was therefore transferred to the Baltic subspecies (replacing H. g. macrorhynchus ), and the name H. g. atlantica resurrected for the Atlantic subspecies. Molecular studies have indicated that the eastern and western Atlantic populations have been genetically distinct for at least one million years, and could potentially be considered separate subspecies. This
14157-495: Was likely more of a fore-flipper swimmer, but could probably swim with either pair. One species, Enaliarctos emlongi , exhibited notable sexual dimorphism , suggesting that this physical characteristic may have been an important driver of pinniped evolution. A closer relative of extant pinnipeds was Pteronarctos , which lived in Oregon 19–15 mya. As in modern seals, the maxilla or upper jaw bone of Pteroarctos intersects with
14278-473: Was originally understood that marine mammals communicate vocally, new research conducted by researchers at Monash University shows that grey seals clap their flippers as another form of communication. They clap their flippers underwater to deter a predator from attacking. If done during the mating season, the clapping can be used as a way to find a potential mate. The Monash researchers point out that seals are typically known for clapping, so this behavior may not be
14399-555: Was partially overrun after a month-long siege, but the attackers were ultimately repelled after the arrival of British reinforcements from Halifax. The most significant impact from this war was the settling of large numbers of Loyalist refugees in the region (34,000 to the 17,000 settlers already there), especially in Shelburne and Parrtown (Saint John). Following the Treaty of Paris in 1783, Loyalist settlers in what would become New Brunswick persuaded British administrators to split
14520-528: Was renamed Cape Breton Island and incorporated into the Colony of Nova Scotia. Some of the Acadians who had been deported came back but went to the eastern coasts of New Brunswick. Both the colonies of Nova Scotia (present-day Nova Scotia and New Brunswick) and St. John's Island (Prince Edward Island) were affected by the American Revolutionary War , largely by privateering against American shipping, but several coastal communities were also
14641-527: Was the first to recognize the pinnipeds as a distinct taxonomic unit; in 1811 he gave the name Pinnipedia to both a family and an order . American zoologist Joel Asaph Allen reviewed the world's pinnipeds in an 1880 monograph , History of North American pinnipeds, a monograph of the walruses, sea-lions, sea-bears and seals of North America . In this publication, he traced the history of names, gave keys to families and genera, described North American species and provided synopses of species in other parts of
