Question: What is the scientific name associated with the small carnivorous mammal and member of the mustelid family that was sought after during the California Fur Rush?

full_context: Document 1: Sea mink: The sea mink ("Neovison macrodon") is a recently extinct species of carnivore from the eastern coast of North America in the family Mustelidae, the largest family in the order Carnivora. It was most closely related to the American mink ("Neovison vison"), with debate about whether or not the sea mink should be considered a subspecies of the American mink (making it "Neovison vison macrodon") or a species of its own. The main justification for a separate-species designation is the size difference between the two minks, but other distinctions have been made, such as its redder fur. The only known remains are fragments unearthed in Native American shell middens. Its actual size is speculative, based largely on tooth remains.
Document 2: Fossa (animal): The fossa ( or ; Malagasy ] ; "Cryptoprocta ferox") is a cat-like, carnivorous mammal endemic to Madagascar. It is a member of the Eupleridae, a family of carnivorans closely related to the mongoose family (Herpestidae). Its classification has been controversial because its physical traits resemble those of cats, yet other traits suggest a close relationship with viverrids (most civets and their relatives). Its classification, along with that of the other Malagasy carnivores, influenced hypotheses about how many times mammalian carnivores have colonized Madagascar. With genetic studies demonstrating that the fossa and all other Malagasy carnivores are most closely related to each other (forming a clade, recognized as the family Eupleridae), carnivorans are now thought to have colonized the island once around 18 to 20 million years ago.
Document 3: Population of Native California: Estimates of the Population of Native Californians prior to and after European contact have varied substantially. Pre-contact estimates range from 133,000 to 705,000 with some recent scholars concluding that these estimates are low. Following the arrival of Europeans in California, disease and primarily the late 19th century California Genocide reduced the population to as low as 25,000. During and after the California Gold Rush, it is estimated that miners and others killed about 4,500 Indigenous people of California between 1849 and 1870. As of 2005, California is the state with the largest self-identified Native American population according to the U.S. Census at 696,600.
Document 4: California Fur Rush: Before the 1849 California Gold Rush, American, English and Russian fur hunters were drawn to Spanish (and then Mexican) California in a California Fur Rush, to exploit its enormous fur resources. Before 1825, these Europeans were drawn to the northern and central California coast to harvest prodigious quantities of southern sea otter ("Enhydra lutris nereis") and fur seals ("Callorhinus ursinus"), and then to the San Francisco Bay Area and Sacramento – San Joaquin River Delta to harvest beaver ("Castor canadensis"), river otter ("Lontra canadensis"), marten, fisher, mink, gray fox ("Urocyon cinereoargenteus"), weasel, and harbor seal. It was California's early fur trade, more than any other single factor, that opened up the West, and the San Francisco Bay Area in particular, to world trade.
Document 5: Fisher (animal): The fisher ("Pekania pennanti") is a small carnivorous mammal native to North America. It is a member of the mustelid family (commonly referred to as the weasel family) and is in the monospecific genus Pekania. The fisher is closely related to but larger than the American marten ("Martes americana"). The fisher is a forest-dwelling creature whose range covers much of the boreal forest in Canada to the northern United States. Names derived from aboriginal languages include pekan, pequam, wejack, and woolang. It is also called a fisher cat, although it is not a feline.
Document 6: Badger: Badgers are short-legged omnivores in the family Mustelidae, which also includes the otters, polecats, weasels, and wolverines. They belong to the caniform suborder of carnivoran mammals. The 11 species of badgers are grouped in three subfamilies: Melinae (Eurasian badgers), Mellivorinae (the honey badger or ratel), and Taxideinae (the American badger). The Asiatic stink badgers of the genus "Mydaus" were formerly included within Melinae (and thus Mustelidae), but recent genetic evidence indicates these are actually members of the skunk family, placing them in the taxonomic family Mephitidae.
Document 7: Canada lynx: The Canada lynx ("Lynx canadensis") or Canadian lynx is a North American mammal of the cat family, Felidae. With the recognised subspecies, it ranges across Canada and into Alaska as well as some parts of the northern United States and extending down the Rocky Mountains to Colorado, where they were reintroduced in the 1990s.
Document 8: American Fur Company: The American Fur Company (AFC) was founded in 1808, by John Jacob Astor, a German immigrant to the United States. During the 18th century, furs had become a major commodity in Europe, and North America became a major supplier. Several British companies, most notably the North West Company and the Hudson's Bay Company, were eventual competitors against Astor and capitalized on the lucrative trade in furs. Astor capitalized on anti-British sentiments and his commercial strategies to become one of the first trusts in American business and a major competitor to the British commercial dominance in North American fur trade. Expanding into many former British fur-trapping regions and trade routes, the company grew to monopolize the fur trade in the United States by 1830, and became one of the largest and wealthiest businesses in the country.
Document 9: California Gold Rush: The California Gold Rush (1848–1855) began on January 24, 1848, when gold was found by James W. Marshall at Sutter's Mill in Coloma, California. The news of gold brought some 300,000 people to California from the rest of the United States and abroad. The sudden influx of immigration and gold into the money supply reinvigorated the American economy, and California became one of the few American states to go directly to statehood without first being a territory, in the Compromise of 1850. The Gold Rush initiated the California Genocide, with 100,000 Native Californians dying between 1848 and 1868. By the time it ended, California had gone from a thinly populated ex-Mexican territory to the home state of the first nominee for the Republican Party.
Document 10: Weasel (disambiguation): A weasel is a small carnivorous mammal.
Document 11: Cougar: The cougar ("Puma concolor"), also commonly known as the mountain lion, puma, panther, or catamount, is a large felid of the subfamily Felinae native to the Americas. Its range, from the Canadian Yukon to the southern Andes of South America, is the greatest of any large wild terrestrial mammal in the Western Hemisphere. An adaptable, generalist species, the cougar is found in most American habitat types. It is the second-heaviest cat in the New World, after the jaguar. Secretive and largely solitary by nature, the cougar is properly considered both nocturnal and crepuscular, although there are daytime sightings. The cougar is more closely related to smaller felines, including the domestic cat (subfamily Felinae), than to any species of subfamily Pantherinae, of which only the jaguar is native to the Americas.
Document 12: Sable: The sable ("Martes zibellina") is a marten species, a small carnivorous mammal inhabiting forest environments, primarily in Russia from the Ural Mountains throughout Siberia, northern Mongolia. Its habitat also leans the borders of eastern Kazakhstan, China, North and South Korea and Hokkaidō in Japan. Its range in the wild originally extended through European Russia to Poland and Scandinavia. It has historically been hunted for its highly valued dark brown or black fur, which remains a luxury good to this day. While hunting of wild animals is still common in Russia, most fur in the market is now commercially farmed.
Document 13: Maritime fur trade: The maritime fur trade was a ship-based fur trade system that focused on acquiring furs of sea otters and other animals from the indigenous peoples of the Pacific Northwest Coast and natives of Alaska. The furs were mostly sold in China in exchange for tea, silks, porcelain, and other Chinese goods, which were then sold in Europe and the United States. The maritime fur trade was pioneered by Russians, working east from Kamchatka along the Aleutian Islands to the southern coast of Alaska. British and Americans entered during the 1780s, focusing on what is now the coast of British Columbia. The trade boomed around the beginning of the 19th century. A long period of decline began in the 1810s. As the sea otter population was depleted, the maritime fur trade diversified and transformed, tapping new markets and commodities, while continuing to focus on the Northwest Coast and China. It lasted until the middle to late 19th century. Russians controlled most of the coast of what is now Alaska during the entire era. The coast south of Alaska endured fierce competition between, and among, British and American trading vessels. The British were the first to operate in the southern sector, but were unable to compete against the Americans, who dominated from the 1790s to the 1830s. The British Hudson's Bay Company entered the coast trade in the 1820s with the intention of driving the Americans away. This was accomplished by about 1840. In its late period, the maritime fur trade was largely conducted by the British Hudson's Bay Company and the Russian-American Company.
Document 14: Logging in the Sierra Nevada: Logging in the Californian Sierra Nevada arose from the desire for economic growth throughout California. The Gold Rush created a high demand for timber in housing construction, mining procedures, and building railroads. In the early days, harvesting of forests were unregulated and within the first 20 years after the gold rush, a third of the timber in the Sierra Nevada was logged. Concern for the forests rose and created a movement towards conservation at the turn of the 19th century, leading to the creation of state and national parks (Yosemite, Sequoia and Grant Grove) and forest reserves, bringing forest land under regulation. Between 1900 and 1940, agencies like the U.S. Forest Service and The National Park Service regulated the use of the Sierra Nevada’s resources.
Document 15: History of California before 1900: Human history in California begins with indigenous Americans first arriving in California some 13,000–15,000 years ago. Exploration and settlement by Europeans along the coasts and in the inland valleys began in the 16th century. California was acquired by the United States under the terms of the 1848 Treaty of Guadalupe Hidalgo following the defeat of Mexico in the Mexican–American War. American westward expansion intensified with the California Gold Rush, beginning in 1849. California joined the Union as a free state in 1850, due to the Compromise of 1850. By the end of the 19th century, California was still largely rural and agricultural, but had a population of about 1.4 million.
