Silver Fox (animal)
The silver fox, sometimes referred to as the black fox, or blue fox, is a melanistic form of the red fox (''Vulpes vulpes''). Silver foxes display a great deal of pelt variation. Some are completely glossy black except for a white colouration on the tip of the tail, giving them a somewhat silvery appearance. Some silver foxes are bluish-grey, and some may have a cinereous colour on the sides. Historically, silver foxes were among the most valued fur-bearers, and their pelts were frequently worn by nobles in Russia, Western Europe, and China. Wild silver foxes do not naturally reproduce exclusively with members of the same coat morph and can be littermates with the common red variety, although captive populations bred for the blue fox fur and as pets are almost exclusively mated with members of the same colour. Description The silver fox's long outer hair can extend as much as beyond the shorter underfur on different parts of the fox's body, particularly under the throat, ...

John Richardson (naturalist)
Sir John Richardson Royal Society of London, FRS FRSE (5 November 1787 – 5 June 1865) was a Scotland, Scottish naval surgeon, natural history, naturalist and Arctic explorer. Life Richardson was born at Nith Place in Dumfries the son of Gabriel Richardson, Provost of Dumfries, and his wife, Anne Mundell. He was educated at Dumfries Grammar School. He was then apprenticed to his maternal uncle, Dr James Mundell, a surgeon in Dumfries. Richardson studied medicine at Edinburgh University, and became a surgeon in the navy in 1807. He traveled with John Franklin in search of the Northwest Passage on the Coppermine Expedition of 1819–1822. Richardson wrote the sections on geology, botany and ichthyology for the official account of the expedition. Franklin and Richardson Mackenzie River expedition, returned to Canada in 1825 and went overland by fur trade routes to the mouth of the Mackenzie River. Franklin was to go as far west as possible and Richardson was to go east to the mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prince Edward Island
Prince Edward Island is an island Provinces and territories of Canada, province of Canada. While it is the smallest province by land area and population, it is the most densely populated. The island has several nicknames: "Garden of the Gulf", "Birthplace of Canadian Confederation, Confederation" and "Cradle of Confederation". Its capital and largest city is Charlottetown. It is one of the three Maritime provinces and one of the four Atlantic provinces. Part of the traditional lands of the Mi'kmaq, it was colonized by the French in 1604 as part of the colony of Acadia. The island, known as Isle St-Jean (St. John's Island), was ceded to the British at the conclusion of the Seven Years' War in 1763 and became part of the colony of Nova Scotia. In 1769, St. John's Island became its own British colony and its name was changed to Prince Edward Island (PEI) in 1798. PEI hosted the Charlottetown Conference in 1864 to discuss a Maritime Union, union of the Maritime provinces; however, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fur Farming
Fur farming is the practice of breeding or raising certain types of animals for their fur. Most of the world's farmed fur was produced by European farmers. In 2018, there were 5,000 fur farms in the EU, located across 22 countries; these areas of production collectively accounted for 50% of the global production of farmed fur. However, by 2023 only 11 countries in the EU still farmed animals for fur, and three of these countries had issued a legal ban on the activity effective within several years. The EU accounted for 63% of global mink production and 70% of fox production. Globally, the top fur producers were China and Finland. Denmark was also leading, accounting for approximately 28% of world mink fur production, until its government culled all of the farmers' stocks without legal authority in 2020. The United States is a major exporter of fur skins. Major export markets include China, Russia, Canada, and the EU. Exports to Asia as a share of total exports grew from 22 ...

Allele Frequency
Allele frequency, or gene frequency, is the relative frequency of an allele (variant of a gene) at a particular locus in a population, expressed as a fraction or percentage. Specifically, it is the fraction of all chromosomes in the population that carry that allele over the total population or sample size. Microevolution is the change in allele frequencies that occurs over time within a population. Given the following: # A particular locus on a chromosome and a given allele at that locus # A population of ''N'' individuals with ploidy ''n'', i.e. an individual carries ''n'' copies of each chromosome in their somatic cells (e.g. two chromosomes in the cells of diploid species) # The allele exists in ''i'' chromosomes in the population then the allele frequency is the fraction of all the occurrences ''i'' of that allele and the total number of chromosome copies across the population, ''i''/(''nN''). The allele frequency is distinct from the genotype frequency, although they a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hudson's Bay Company
The Hudson's Bay Company (HBC), originally the Governor and Company of Adventurers of England Trading Into Hudson’s Bay, is a Canadian holding company of department stores, and the oldest corporation in North America. It was the owner of the namesake Hudson's Bay (department store), Hudson's Bay department stores (colloquially The Bay), and also owns or manages approximately of gross leasable real estate through its HBC Properties and Investments business unit. HBC previously owned the full-line Saks Fifth Avenue and off-price Saks Off 5th in the United States, which were spun-off into the Saks Global holding company in 2024. After incorporation by royal charter issued in 1670 by Charles II of England, King Charles II, the company was granted a right of "sole trade and commerce" over an expansive area of land known as Rupert's Land, comprising much of the Hudson Bay drainage basin. This right gave the company a monopoly, commercial monopoly over that area. The HBC functioned ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Beaver
The North American beaver (''Castor canadensis'') is one of two extant beaver species, along with the Eurasian beaver (''Castor fiber''). It is native to North America and has been introduced in South America (Patagonia) and Europe (primarily Finland and Karelia). The North American beaver is one of the national symbols of Canada and the official state mammal of Oregon and New York. North American (Canadian) beavers are widespread across the continental United States, Canada, southern Alaska, and some parts of northern Mexico. In Canada and the United States, the North American beaver is often referred to simply as "beaver", although this can cause some confusion because another distantly related rodent, '' Aplodontia rufa'', is often called the "mountain beaver". Other vernacular names, including American beaver and Canadian beaver, distinguish this species from the other extant beaver species, '' Castor fiber'', which is native to Eurasia.

Feeding The Silver Foxes (c 1901)
Eating (also known as consuming) is the ingestion of food. In biology, this is typically done to provide a heterotrophic organism with energy and nutrients and to allow for growth. Animals and other heterotrophs must eat in order to survive – carnivores eat other animals, herbivores eat plants, omnivores consume a mixture of both plant and animal matter, and detritivores eat detritus. Fungi digest organic matter outside their bodies as opposed to animals that digest their food inside their bodies. For humans, eating is more complex, but is typically an activity of daily living. Physicians and dieticians consider a healthful diet essential for maintaining peak physical condition. Some individuals may limit their amount of nutritional intake. This may be a result of a lifestyle choice: as part of a diet or as religious fasting. Limited consumption may be due to hunger or famine. Overconsumption of calories may lead to obesity and the reasons behind it are myriad, however, its p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fur Silverfox
A fur is a soft, thick growth of hair that covers the skin of almost all mammals. It consists of a combination of oily guard hair on top and thick underfur beneath. The guard hair keeps moisture from reaching the skin; the underfur acts as an insulating blanket that keeps the animal warm. The fur of mammals has many uses: protection, sensory purposes, waterproofing, and camouflaging, with the primary usage being thermoregulation. The types of hair include * ''definitive'', which may be shed after reaching a certain length; * '' vibrissae'', which are sensory hairs and are most commonly whiskers; * ''pelage'', which consists of guard hairs, under-fur, and awn hair; * '' spines'', which are a type of stiff guard hair used for defense in, for example, porcupines; * ''bristles'', which are long hairs usually used in visual signals, such as the mane of a lion; * ''velli'', often called "down fur", which insulates newborn mammals; and * ''wool'', which is long, soft, and often ...
