Bear Attack
A bear attack is an attack by a bear on another animal, although it usually refers to a bear attacking a human or domestic pet such as a dog. Bear attacks are of particular concern for those who are in bear habitats. They can be fatal and often hikers, dogs, hunters, fishers, and others in bear country take precautions against bear attacks. Stephen Herrero, a Canadian biologist, reports that during the 1990s, bears killed around three people a year in the U.S. and Canada, as compared to the 30 to 50 people killed every year by dogs. Causes Almost all recorded bear attacks in the wild have resulted from the human surprising the bear. Hunters are the people most at risk of bear attacks because, as Tom Smith, a U.S. Geographical Survey research biologist, describes, "Hunters typically aren't making any noise, and they sleuth around while wearing camo."Batin, Christopher. ''Bear Attacks!'' p. 46 Hunters try to be silent and, though many hunters wear reflective clothing so as not to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Female Black Grizzly Bear (Ursus Arctos Horribilis)
Female ( symbol: ♀) is the sex of an organism that produces the large non-motile ova (egg cells), the type of gamete (sex cell) that fuses with the male gamete during sexual reproduction. A female has larger gametes than a male. Females and males are results of the anisogamous reproduction system, wherein gametes are of different sizes, unlike isogamy where they are the same size. The exact mechanism of female gamete evolution remains unknown. In species that have males and females, sex-determination may be based on either sex chromosomes, or environmental conditions. Most female mammals, including female humans, have two X chromosomes. Female characteristics vary between different species with some species having pronounced secondary female sex characteristics, such as the presence of pronounced mammary glands in mammals. In humans, the word ''female'' can also be used to refer to gender in the social sense of gender role or gender identity. Etymology and usage T ...

Brown Bear
The brown bear (''Ursus arctos'') is a large bear species found across Eurasia and North America. In North America, the populations of brown bears are called grizzly bears, while the subspecies that inhabits the Kodiak Islands of Alaska is known as the Kodiak bear. It is one of the largest living terrestrial members of the Order (biology), order Carnivora, rivaled in size only by its closest relative, the polar bear (''Ursus maritimus''), which is much less variable in size and slightly bigger on average. The brown bear's range includes parts of Russia, Central Asia, the Himalayas, China, Canada, the United States, Hokkaido, Scandinavia, Finland, the Balkans, the Picos de Europa and the Carpathian region (especially Romania), Iran, Anatolia, and the Caucasus. The brown bear is recognized as a national and state animal in several European countries. While the brown bear's range has shrunk, and it has faced local extinctions across its wide range, it remains listed as a least con ...

Pine Nut
Pine nuts, also called piñón (), pinoli (), pignoli or chilgoza (), are the edible seeds of pines (family Pinaceae, genus ''Pinus''). According to the Food and Agriculture Organization, only 29 species provide edible nuts, while 20 are traded locally or internationally owing to their seed size being large enough to be worth harvesting; in other pines, the seeds are also edible, but are too small to be of notable value as a human food. Species and geographic spread In Asia, two species in particular are widely harvested: Korean pine (''Pinus koraiensis'') in northeast Asia (the most important species in international trade) and chilgoza pine (''Pinus gerardiana'') in the western Himalaya. Four other species, Siberian pine (''Pinus sibirica''), Siberian dwarf pine (''Pinus pumila''), Chinese white pine (''Pinus armandii'') and lacebark pine (''Pinus bungeana''), are also used to a lesser extent. Russia is the largest producer of ''Pinus sibirica'' nuts in the world, followed b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buffalo Berry
''Shepherdia'', commonly called buffaloberry or bullberry, is a genus of small shrubs in the Elaeagnaceae family. The plants are native to northern and western North America. They are non-legume nitrogen fixers. ''Shepherdia'' is dioecious, with male and female flowers produced on separate plants. Species The genus has three species: Fruit The berry is recognizable by being a dark shade of red, with little white dots on them. They are rough to the touch, and are found on both trees and shrubs. Wildlife The plants have rather bitter-tasting berries. The fruit are often eaten by bears, which by legend, prefer the berries to maintain fat stores during hibernation. Buffaloberries are used as food plants by the larvae of some Lepidoptera species, including ''Ectropis crepuscularia'' (recorded from ''S. canadensis'') and ''Coleophora elaeagnisella''. As food Buffaloberries are sour and can be made into jam, pie, jelly, syrup, soups, or prepared like cranberry sauce Cranbe ...

Huckleberry
Huckleberry is a name used in North America for several plants in the family Ericaceae, in two closely related genera: ''Vaccinium'' and ''Gaylussacia''. The huckleberry is the state fruit of Idaho. Nomenclature The name 'huckleberry' is a North American variation of the English dialectal name variously called 'hurtleberry' or 'whortleberry' () for the Vaccinium myrtillus, bilberry. In North America the name was applied to numerous plant variations all bearing small berries with colors that may be red, blue or black. It is the common name for various ''Gaylussacia'' species, and some ''Vaccinium'' species, such as ''Vaccinium parvifolium'', the ''red huckleberry'', and is also applied to other ''Vaccinium'' species which may also be called blueberry, blueberries depending upon local custom, as in New England and parts of Appalachia. Taxonomy ''Gaylussacia'' Four species of huckleberries in the genus ''Gaylussacia'' are common in eastern North America, especially Gaylussacia b ...

Grizzly Bear
The grizzly bear (''Ursus arctos horribilis''), also known as the North American brown bear or simply grizzly, is a population or subspecies of the brown bear inhabiting North America. In addition to the mainland grizzly (''Ursus arctos horribilis''), other morphological forms of brown bear in North America are sometimes identified as grizzly bears. These include three living populations—the Kodiak bear (''U. a. middendorffi''), the Kamchatka bear (''U. a. beringianus''), and the peninsular grizzly (''U. a. gyas'')—as well as the extinct California grizzly (''U. a. californicus''†), Mexican grizzly (formerly ''U. a. nelsoni''†), and Ungava-Labrador grizzly (formerly ''U. a. ungavaesis''†). On average, grizzly bears near the coast tend to be larger while inland grizzlies tend to be smaller. The Ussuri brown bear (''U. a. lasiotus''), inhabiting Russia, Northern China, Japan, and Korea, is sometimes referred to as the "black grizzly", although it is no more closely ...

Indigenous Peoples Of The Americas
The Indigenous peoples of the Americas are the inhabitants of the Americas before the arrival of the European settlers in the 15th century, and the ethnic groups who now identify themselves with those peoples. Many Indigenous peoples of the Americas were traditionally hunter-gatherers and many, especially in the Amazon basin, still are, but many groups practiced aquaculture and agriculture. While some societies depended heavily on agriculture, others practiced a mix of farming, hunting, and gathering. In some regions, the Indigenous peoples created monumental architecture, large-scale organized cities, city-states, chiefdoms, states, kingdoms, republics, confederacies, and empires. Some had varying degrees of knowledge of engineering, architecture, mathematics, astronomy, writing, physics, medicine, planting and irrigation, geology, mining, metallurgy, sculpture, and gold smithing. Many parts of the Americas are still populated by Indigenous peoples; some countries have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Platinum
Platinum is a chemical element with the symbol Pt and atomic number 78. It is a dense, malleable, ductile, highly unreactive, precious, silverish-white transition metal. Its name originates from Spanish , a diminutive of "silver". Platinum is a member of the platinum group of elements and group 10 of the periodic table of elements. It has six naturally occurring isotopes. It is one of the rarer elements in Earth's crust, with an average abundance of approximately 5 μg/kg. It occurs in some nickel and copper ores along with some native deposits, mostly in South Africa, which accounts for ~80% of the world production. Because of its scarcity in Earth's crust, only a few hundred tonnes are produced annually, and given its important uses, it is highly valuable and is a major precious metal commodity. Platinum is one of the least reactive metals. It has remarkable resistance to corrosion, even at high temperatures, and is therefore considered a noble metal. Consequent ...

Eurasian Brown Bear
The Eurasian brown bear (''Ursus arctos arctos'') is one of the most common subspecies of the brown bear, and is found in much of Eurasia. It is also called the European brown bear, common brown bear, common bear, and colloquially by many other names. The genetic diversity of present-day brown bears (''Ursus arctos'') has been extensively studied over the years and appears to be geographically structured into five main clades based upon analysis of the mtDNA. Description The Eurasian brown bear has brown fur, which ranges from yellowish-brown to dark brown, red-brown, and almost black in some cases; albinism has also been recorded. The fur is dense to varying degrees and the hair can grow up to in length. The head normally is quite round in shape and has relatively small rounded ears, a wide skull and a mouth equipped with 42 teeth, including predatory teeth. It has a powerful bone structure and large paws equipped with claws that can grow up to in length. The weight varie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
East Siberian Brown Bear
The East Siberian brown bear (''Ursus arctos collaris'') is a population or subspecies of brown bear which ranges from eastern Siberia, beginning at the Yenisei river, north to the Arctic Circle, as far as Trans-Baikaliya, the Stanovoy Range, the Lena River, Kolyma and generally throughout Yakutia and the Altai Mountains. The subspecies is also present in northern Mongolia. Size East Siberian bears are intermediate in size to Eurasian brown bears and Kamchatka brown bears, though large individuals can attain the size of the latter. Their skulls are invariably larger than those of Eurasian brown bears and are apparently larger than those of Kamchatka brown bears. Adult males have skulls measuring in length, and wide at the zygomatic arches. They have long, dense and soft fur which is similar in colour to that of Eurasian brown bears, though darker coloured individuals predominate. Taxonomic history Originally, Cuvier's trinomial definition for this subspecies was limited ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
