Persistence Hunting
Persistence hunting is pursuit until the prey can no longer flee and succumbs to exhaustion or heat stroke. History and definition Some researchers have insisted that the point of persistence hunting is not to induce exhaustion but specifically to induce heat stroke. However, a decade later, they understood persistence hunting to include pursuit until injury or heat stroke or exhaustion; and driving prey to ambushes, natural traps like cliffs and rivers and ravines, or man-made ditches and stakes. There do not seem to be descriptions which take account of ''heat dissipation theory''. Hunters Startled animals respond in characteristic ways that may be effective against animal predators. People learn how prey respond and plan (and prepare themselves) to overcome that response. They learn how to monitor their own condition and stay within their limits, while pushing the prey animal beyond its physiological limits. Research and discussion about persistence hunting has often b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pursuit Predation
Pursuit predation is a form of predation in which predators actively give chase to their prey, either solitarily or as a group. It is an alternate predation strategy to ambush predation — pursuit predators rely on superior speed, endurance and/or teamwork to seize the prey, while ambush predators use stealth, luring, the use of surroundings and the element of surprise to capture the prey. While the two patterns of predation are not mutually exclusive, morphological differences in an organism's body plan can create an evolutionary bias favoring either type of predation. Pursuit predation is typically observed in carnivorous species within the kingdom Animalia, such as cheetahs, lions, wolves and early ''Homo'' species. The chase can be initiated either by the predator, or by the prey if it is alerted to a predator's presence and attempt to flee before the predator gets close. The chase ends either when the predator successfully catches up and tackles the prey, or when the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pinole
Pinole, also called pinol or pinolillo, is roasted ground maize, which is then mixed with a combination of cocoa, agave, cinnamon, chia seeds, vanilla, or other spices. The resulting powder is then used as a nutrient-dense ingredient to make different foods, such as cereals, baked goods, tortillas, and beverages. The name comes from the Nahuatl word ''pinolli'', meaning cornmeal. Today, pinole is generally made by hand using wood-burning adobe ovens and a stone and pestle, and is still consumed in certain, often rural, parts of Latin America. Pinole is considered the national beverage of Nicaragua and Honduras. Nutrient content Depending on the type of pinole and the quality of its ingredients, pinole can be high in key vitamins and nutrients, including protein, amino acids, fiber, and antioxidants. Due to the large amount of fiber and the slow digestion of the maize, pinole also has a very high satiety effect, leaving those who consume it feeling full for a longer period ...

Outdoor Life
''Outdoor Life'' is an outdoors magazine about camping, fishing, hunting, and survival. It is a sister magazine of ''Field & Stream''. Together with ''Sports Afield'', they are considered the Big Three of American outdoor publishing by Money (magazine). ''Outdoor Life'' was launched in Denver, Colorado, in January 1898. Founder and editor-in-chief (1898–1929), J. A. McGuire, intended ''Outdoor Life'' to be a magazine for sportsmen, written by sportsmen, covering all aspects of the outdoor arena. History The first issue covered topics including a moose hunt in Alaska and advice about Native Americans. Some of the original sections were titled, "Photography", "Trap and Target", and "In the Game and Field". ''Outdoor Life'' was an innovative publication. In 1903, the first photograph was printed on the cover in black and white. A short time later, in 1906, the first color cover appeared on the magazine.

Shortgrass Prairie
The shortgrass prairie is an ecosystem located in the Great Plains of North America. The two most dominant grasses in the shortgrass prairie are blue grama (''Bouteloua gracilis'') and buffalograss (''Bouteloua dactyloides''), the two less dominant grasses in the prairie are greasegrass (''Tridens flavus'') and sideoats grama (''Bouteloua curtipendula''). The prairie was formerly maintained by grazing pressure of American bison, which is the keystone species. Due to its semiarid climate, the shortgrass prairie receives on average less precipitation than that of the tall and mixed grass prairies to the east. The prairie includes lands to the west as far as the eastern foothills of the Rocky Mountains and extends east as far as Nebraska and north into Saskatchewan. The prairie stretches through parts of Alberta, Wyoming, Montana, North Dakota, South Dakota, and Kansas, and passes south through the high plains of Colorado, Oklahoma, Texas, and New Mexico.

Pronghorn
The pronghorn (, ) (''Antilocapra americana'') is a species of artiodactyl (even-toed, hoofed) mammal indigenous to interior western and central North America. Though not an antelope, it is known colloquially in North America as the American antelope, prong buck, pronghorn antelope and prairie antelope, because it closely resembles the antelopes of the Old World and fills a similar ecological niche due to parallel evolution. It is the only surviving member of the family Antilocapridae. During the Pleistocene epoch, about 11 other antilocaprid species existed in North America.Smithsonian Institution. North American MammalsPronghorn ''Antilocapra americana''/ref> Three other genera (''Capromeryx'', '' Stockoceros'' and ''Tetrameryx'') existed when humans entered North America but are now extinct. As a member of the superfamily Giraffoidea, the pronghorn's closest living relatives are the giraffe and okapi. See Fig. S10 in Supplementary Information. The Giraffoidea are in tu ...

The Life Of Mammals
''The Life of Mammals'' is a nature documentary series written and presented by David Attenborough, first transmitted in the United Kingdom from 20 November 2002. A study of the evolution and habits of the various mammal species, it was the fourth of Attenborough's specialised surveys following his major trilogy that began with ''Life on Earth''. Each of the ten episodes looks at one (or several closely related) mammal groups and discusses the different facets of their day-to-day existence and their evolutionary origins. All the programmes are of 50 minutes' duration except the last, which extends to 59 minutes. The series was produced by the BBC Natural History Unit in conjunction with the Discovery Channel. The executive producer was Mike Salisbury and the music was composed by Dan Jones and Ben Salisbury. It was later shown on Animal Planet. Part of David Attenborough's ''Life'' series, it was preceded by ''The Life of Birds'' (1998), and followed by ''Life in the Undergrowt ...

Preferred Walking Speed
The preferred walking speed is the speed at which humans or animals choose to walk. Many people tend to walk at about . Individuals find slower or faster speeds uncomfortable. Horses have also demonstrated normal, narrow distributions of preferred walking speed within a given gait, which suggests that the process of speed selection may follow similar patterns across species. Preferred walking speed has important clinical applications as an indicator of mobility and independence. For example, elderly people or people suffering from osteoarthritis must walk more slowly. Improving (increasing) people's preferred walking speed is a significant clinical goal in these populations. People have suggested mechanical, energetic, physiological and psychological factors as contributors to speed selection. Probably, individuals face a trade-off between the numerous costs associated with different walking speeds, and select a speed which minimizes these costs. For example, they may trade off ...

Central Kalahari Game Reserve
Central Kalahari Game Reserve is an extensive national park in the Kalahari Desert of Botswana. Established in 1961 it covers an area of (larger than the Netherlands, and almost 10% of Botswana's total land area), making it the second largest game reserve in the world. History The Bushmen, or San, have inhabited the lands for thousands of years since they roamed the area as nomadic hunters. However, since the mid-1990s the Botswana government has tried to relocate the Bushmen from the reserve, claiming they were a drain on financial resources despite revenues from tourism. In 1997, three quarters of the entire San population were relocated from the reserve, and in October 2005 the government had resumed the forced relocation into resettlement camps outside of the park leaving only about 250 permanent occupiers. In 2006 a Botswana court proclaimed the eviction illegal and affirmed the Bushmen's right to return to living in the reserve. However, as of 2015 most Bushmen are block ...
