Queen Charlotte Islands Caribou
The Queen Charlotte Islands caribou or Dawson's caribou (''Rangifer arcticus dawsoni'') is an extinct subspecies of the Arctic caribou (''R. arcticus'') that once lived on Graham Island, the largest of the islands of Haida Gwaii in British Columbia, Canada. Possible causes of its extinction include habitat destruction, introduced disease and overhunting. It was grey in appearance. The last three caribou were killed in 1908 and can be seen at the Royal British Columbia Museum, where their pelts and bones are preserved and displayed. Recent analysis of mtDNA Mitochondrial DNA (mtDNA or mDNA) is the DNA located in mitochondria, cellular organelles within eukaryotic cells that convert chemical energy from food into a form that cells can use, such as adenosine triphosphate (ATP). Mitochondrial DNA ... suggests that the Queen Charlotte Islands caribou was not genetically distinct from the subspecies from the Canadian mainland.Byun, S.A.; B.F. Koop, and T.E. Reimchen. (2002).

Ernest Thompson Seton
Ernest Thompson Seton (born Ernest Evan Thompson August 14, 1860 – October 23, 1946) was an English-born Canadian-American author, wildlife artist, founder of the Woodcraft Indians in 1902 (renamed Woodcraft League of America), and one of the founding pioneers of the Boy Scouts of America (BSA) in 1910. Seton also influenced Lord Baden-Powell, the founder of one of the first Scouting organizations. His writings were published in the United Kingdom, Canada, the US, and the USSR; his notable books related to Scouting include ''The Birch Bark Roll'' and the '' Boy Scout Handbook''. He incorporated what he believed to be American Indian elements into the traditions of the BSA. Early life Seton was born in South Shields, County Durham, England of Scottish parents. His family emigrated to Canada in 1866. After settling in Lindsay, Ontario Seton spent most (after 1870) of his childhood in Toronto, and the family is known to have lived at 6 Aberdeen Avenue in Cabbagetown. As a ...

British Columbia
British Columbia (commonly abbreviated as BC) is the westernmost province of Canada, situated between the Pacific Ocean and the Rocky Mountains. It has a diverse geography, with rugged landscapes that include rocky coastlines, sandy beaches, forests, lakes, mountains, inland deserts and grassy plains, and borders the province of Alberta to the east and the Yukon and Northwest Territories to the north. With an estimated population of 5.3million as of 2022, it is Canada's third-most populous province. The capital of British Columbia is Victoria and its largest city is Vancouver. Vancouver is the third-largest metropolitan area in Canada; the 2021 census recorded 2.6million people in Metro Vancouver. The first known human inhabitants of the area settled in British Columbia at least 10,000 years ago. Such groups include the Coast Salish, Tsilhqotʼin, and Haida peoples, among many others. One of the earliest British settlements in the area was Fort Victoria, established ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Mammal Extinctions Since 1500
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla (cetaceans and even-toed ungulates), and the Carnivora (cats, dogs, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, together with Sauropsida ...

MtDNA
Mitochondrial DNA (mtDNA or mDNA) is the DNA located in mitochondria, cellular organelles within eukaryotic cells that convert chemical energy from food into a form that cells can use, such as adenosine triphosphate (ATP). Mitochondrial DNA is only a small portion of the DNA in a eukaryotic cell; most of the DNA can be found in the cell nucleus and, in plants and algae, also in plastids such as chloroplasts. Human mitochondrial DNA was the first significant part of the human genome to be sequenced. This sequencing revealed that the human mtDNA includes 16,569 base pairs and encodes 13 proteins. Since animal mtDNA evolves faster than nuclear genetic markers, it represents a mainstay of phylogenetics and evolutionary biology. It also permits an examination of the relatedness of populations, and so has become important in anthropology and biogeography. Origin Nuclear and mitochondrial DNA are thought to be of separate evolutionary origin, with the mtDNA being derived from t ...

Royal British Columbia Museum
Founded in 1886, the Royal British Columbia Museum (sometimes referred to as Royal BC Museum) consists of The Province of British Columbia's natural and human history museum as well as the British Columbia Provincial Archives. The museum is located in Victoria, British Columbia, Canada. The "Royal" title was approved by Queen Elizabeth II and bestowed by HRH Prince Philip in 1987, to coincide with a Royal tour of that year. The museum merged with the British Columbia Provincial Archives in 2003. The Royal BC Museum includes three permanent galleries: Natural History, Becoming BC, and the First Peoples Gallery. The museum's collections comprise approximately 7 million objects, including natural history specimens, artifacts, and archival records.2010-11 Annual Report, p. 40 The natural history collections have 750,000 records of specimens almost exclusively from BC and neighbouring states, provinces, or territories. The collections are divided into eight disciplines: Entomology, B ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Hunting
Hunting is the human activity, human practice of seeking, pursuing, capturing, or killing wildlife or feral animals. The most common reasons for humans to hunt are to harvest food (i.e. meat) and useful animal products (fur/hide (skin), hide, bone/tusks, horn (anatomy), horn/antler, etc.), for recreation/taxidermy (see trophy hunting), to remove predators dangerous to humans or domestic animals (e.g. wolf hunting), to pest control, eliminate pest (organism), pests and nuisance animals that damage crops/livestock/poultry or zoonosis, spread diseases (see varmint hunting, varminting), for trade/tourism (see safari), or for conservation biology, ecological conservation against overpopulation and invasive species. Recreationally hunted species are generally referred to as the ''game (food), game'', and are usually mammals and birds. A person participating in a hunt is a hunter or (less commonly) huntsman; a natural area used for hunting is called a game reserve; an experienced hun ...

Habitat Destruction
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...

Canada
Canada is a country in North America. Its ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, covering over , making it the world's second-largest country by total area. Its southern and western border with the United States, stretching , is the world's longest binational land border. Canada's capital is Ottawa, and its three largest metropolitan areas are Toronto, Montreal, and Vancouver. Indigenous peoples have continuously inhabited what is now Canada for thousands of years. Beginning in the 16th century, British and French expeditions explored and later settled along the Atlantic coast. As a consequence of various armed conflicts, France ceded nearly all of its colonies in North America in 1763. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces. This began an accretion of provinces an ...

Haida Gwaii
Haida Gwaii (; hai, X̱aaydag̱a Gwaay.yaay / , literally "Islands of the Haida people") is an archipelago located between off the northern Pacific coast of Canada. The islands are separated from the mainland to the east by the shallow Hecate Strait. Queen Charlotte Sound lies to the south, with Vancouver Island beyond. To the north, the disputed Dixon Entrance separates Haida Gwaii from the Alexander Archipelago in the U.S. state of Alaska. Haida Gwaii consists of two main islands: Graham Island () in the north and Moresby Island (, literally: south people island half, or "Islands of Beauty") in the south, along with approximately 400 smaller islands with a total landmass of . Other major islands include Anthony Island ( / ), Burnaby Island (), Lyell Island, Louise Island, Alder Island ( / ), and Kunghit Island. (For a fuller, but still incomplete, list see List of islands of British Columbia.) Part of the Canadian province of British Columbia, the islands were known f ...

Boreal Woodland Caribou
The boreal woodland caribou (''Rangifer tarandus caribou''; but subject to a recent taxonomic revision. See Reindeer: taxonomy), also known as woodland caribou, boreal forest caribou and forest-dwelling caribou, is a North American subspecies of reindeer (or caribou in North America) found only in Canada. Unlike the Porcupine caribou and barren-ground caribou, boreal woodland caribou are primarily (but not always) sedentary. In their 2012 report entitled "Recovery Strategy for the Woodland Caribou (Rangifer tarandus caribou), Boreal population, in Canada", Environment Canada and SARA refer to the woodland caribou as "boreal caribou". "Woodland Caribou (''Rangifer tarandus caribou''), Boreal population herein referred to as "boreal caribou", assessed in May 2002 as threatened by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC).

Graham Island
Graham Island () is the largest island in the Haida Gwaii archipelago (previously known as the Queen Charlotte Islands), lying off the mainland coast of British Columbia, Canada. It is separated by the narrow Skidegate Channel from the other principal island of the group to the south, Moresby Island (''T'aaxwii X̱aaydag̱a Gwaay.yaay linag̱waay'' in the language of the Haida people). It has a population of 3,858 (2016 census), an area of , and is the 101st largest island in the world and Canada's 22nd largest island. Graham Island was named in 1853 by James Charles Prevost, commander of HMS ''Virago'', for Sir James Graham, 2nd Baronet, who was First Lord of the Admiralty at the time.
