The coyote, Canis latrans, is a canine native to North America. It is smaller than its close relative, the gray wolf, smaller than the related eastern wolf and red wolf, it fills much of the same ecological niche as the golden jackal does in Eurasia, though it is larger and more predatory, is sometimes called the American jackal by zoologists. The coyote is listed as least concern by the International Union for Conservation of Nature due to its wide distribution and abundance throughout North America, southwards through Mexico, into Central America; the species is able to adapt to and expand into environments modified by humans. It is enlarging its range, with coyotes moving into urban areas in the Eastern U. S. and was sighted in eastern Panama for the first time in 2013. As of 2005, 19 coyote subspecies are recognized; the average male weighs the average female 7 to 18 kg. Their fur color is predominantly light gray and red or fulvous interspersed with black and white, though it varies somewhat with geography.
It is flexible in social organization, living either in a family unit or in loosely knit packs of unrelated individuals. It has a varied diet consisting of animal meat, including deer, hares, birds, amphibians and invertebrates, though it may eat fruits and vegetables on occasion, its characteristic vocalization is a howl made by solitary individuals. Humans are the coyote's greatest threat, followed by gray wolves. In spite of this, coyotes sometimes mate with gray, eastern, or red wolves, producing "coywolf" hybrids. In the northeastern United States and eastern Canada, the eastern coyote is the result of various historical and recent matings with various types of wolves. Genetic studies show that most North American wolves contain some level of coyote DNA; the coyote is a prominent character in Native American folklore in the Southwestern United States and Mexico depicted as a trickster that alternately assumes the form of an actual coyote or a man. As with other trickster figures, the coyote uses deception and humor to rebel against social conventions.
The animal was respected in Mesoamerican cosmology as a symbol of military might. After the European colonization of the Americas, it was reviled in Anglo-American culture as a cowardly and untrustworthy animal. Unlike wolves, which have undergone an improvement of their public image, attitudes towards the coyote remain negative. Coyote males average 8 to 20 kg in weight, while females average 7 to 18 kg, though size varies geographically. Northern subspecies, which average 18 kg, tend to grow larger than the southern subspecies of Mexico, which average 11.5 kg. Body length ranges on average from 1.0 to 1.35 m, tail length 40 cm, with females being shorter in both body length and height. The largest coyote on record was a male killed near Afton, Wyoming, on November 19, 1937, which measured 1.5 m from nose to tail, weighed 34 kg. Scent glands are a bluish-black color; the color and texture of the coyote's fur varies somewhat geographically. The hair's predominant color is light gray and red or fulvous, interspersed around the body with black and white.
Coyotes living at high elevations tend to have more black and gray shades than their desert-dwelling counterparts, which are more fulvous or whitish-gray. The coyote's fur consists of soft underfur and long, coarse guard hairs; the fur of northern subspecies is longer and denser than in southern forms, with the fur of some Mexican and Central American forms being hispid. Adult coyotes have a sable coat color, dark neonatal coat color, bushy tail with an active supracaudal gland, a white facial mask. Albinism is rare in coyotes; the coyote is smaller than the gray wolf, but has longer ears and a larger braincase, as well as a thinner frame and muzzle. The scent glands are the same color, its fur color variation is much less varied than that of a wolf. The coyote carries its tail downwards when running or walking, rather than horizontally as the wolf does. Coyote tracks can be distinguished from those of dogs by less rounded shape. Unlike dogs, the upper canines of coyotes extend past the mental foramina.
At the time of the European colonization of the Americas, coyotes were confined to open plains and arid regions of the western half of the continent. In early post-Columbian historical records, distinguishing between coyotes and wolves is difficult. One record from 1750 in Kaskaskia, written by a local priest, noted that the "wolves" encountered there were smaller and less daring than European wolves. Another account from the early 1800s in Edwards County mentioned wolves howling at night, though these were coyotes; this species was encountered several times during the Lewis and Clark Expedition, though it was well known to European traders on the upper Missouri. Lewis, writing on 5 May 1805, in northeastern Montana, described the coyote in these terms: The small woolf or burrowing dog of the prairies are the inhabitants invariably of the open plains.
Rabbits are small mammals in the family Leporidae of the order Lagomorpha. Oryctolagus cuniculus includes the European rabbit species and its descendants, the world's 305 breeds of domestic rabbit. Sylvilagus includes 13 wild rabbit species, among them the 7 types of cottontail; the European rabbit, introduced on every continent except Antarctica, is familiar throughout the world as a wild prey animal and as a domesticated form of livestock and pet. With its widespread effect on ecologies and cultures, the rabbit is, in many areas of the world, a part of daily life—as food, clothing, a companion, as a source of artistic inspiration. Male rabbits are called bucks. An older term for an adult rabbit is coney. Another term for a young rabbit is bunny, though this term is applied informally to rabbits especially domestic ones. More the term kit or kitten has been used to refer to a young rabbit. A group of rabbits is known as a nest. A group of baby rabbits produced from a single mating is referred to as a litter, a group of domestic rabbits living together is sometimes called a herd.
Rabbits and hares were classified in the order Rodentia until 1912, when they were moved into a new order, Lagomorpha. Below are some of the species of the rabbit. Order Lagomorpha Family Leporidae Hares are precocial, born mature and mobile with hair and good vision, while rabbits are altricial, born hairless and blind, requiring closer care. Hares live a solitary life in a simple nest above the ground, while most rabbits live in social groups underground in burrows or warrens. Hares are larger than rabbits, with ears that are more elongated, with hind legs that are larger and longer. Hares have not been domesticated, while descendants of the European rabbit are bred as livestock and kept as pets. Rabbits have long been domesticated. Beginning in the Middle Ages, the European rabbit has been kept as livestock, starting in ancient Rome. Selective breeding has generated a wide variety of rabbit breeds, many of which are kept as pets; some strains of rabbit have been bred as research subjects. As livestock, rabbits are bred for their fur.
The earliest breeds were important sources of meat, so became larger than wild rabbits, but domestic rabbits in modern times range in size from dwarf to giant. Rabbit fur, prized for its softness, can be found in a broad range of coat colors and patterns, as well as lengths; the Angora rabbit breed, for example, was developed for its long, silky fur, hand-spun into yarn. Other domestic rabbit breeds have been developed for the commercial fur trade, including the Rex, which has a short plush coat; because the rabbit's epiglottis is engaged over the soft palate except when swallowing, the rabbit is an obligate nasal breather. Rabbits have two sets of one behind the other; this way they can be distinguished from rodents, with which they are confused. Carl Linnaeus grouped rabbits and rodents under the class Glires. However, recent DNA analysis and the discovery of a common ancestor has supported the view that they do share a common lineage, thus rabbits and rodents are now referred to together as members of the superorder Glires.
Since speed and agility are a rabbit's main defenses against predators, rabbits have large hind leg bones and well developed musculature. Though plantigrade at rest, rabbits are on their toes while running, assuming a more digitigrade form. Rabbits use their strong claws for defense; each front foot has four toes plus a dewclaw. Each hind foot has four toes. Most wild rabbits have full, egg-shaped bodies; the soft coat of the wild rabbit is agouti in coloration. The tail of the rabbit is dark on white below. Cottontails have white on the top of their tails; as a result of the position of the eyes in its skull, the rabbit has a field of vision that encompasses nearly 360 degrees, with just a small blind spot at the bridge of the nose. The anatomy of rabbits' hind limbs are structurally similar to that of other land mammals and contribute to their specialized form of locomotion; the Bones of the hind limbs consist of long bones as well as short bones. These bones are created through endochondral ossification during development.
Like most land mammals, the round head of the femur articulates with the acetabulum of the ox coxae. The femur articulates with the tibia, but not the fibula, fused to the tibia; the tibia and fibula articulate with the tarsals of the pes called the foot. The hind limbs of the rabbit are longer than the front limbs; this allows them to produce their hopping form of locomotion. Longer hind limbs are more capable of producing faster speeds. Hares, which have longer legs than cottontail rabbits, are able to move faster. Rabbits stay just on their toes; the hind feet have four long toes that allow for this and are webbed to prevent them from spreading when hopping. Rabbits do not have paw
Arrian of Nicomedia was a Greek historian, public servant, military commander and philosopher of the Roman period. The Anabasis of Alexander by Arrian is considered the best source on the campaigns of Alexander the Great. However, more even though modern scholars have preferred Arrian to other extant primary sources, this attitude towards Arrian is beginning to change in the light of studies into Arrian's method. Arrian was born in the provincial capital of Bithynia. Dio called him Flavius Arrianus Nicomediansis. In respect of his birth date, sources provide similar dates for his birth; the line of reasoning for dates belonging to 85-90 AD is from the fact of Arrian being made a consul around 130 AD, the usual age for this, during this period, being forty-two years of age.. His family was from the Greek provincial aristocracy, his full name, L. Flavius Arrianus, indicates that he was a Roman citizen, suggesting that the citizenship went back several generations to the time of the Roman conquest some 170 years before.
Sometime during the 2nd century AD while in Epirus Nicopolis, Arrian attended lectures of Epictetus of Nicopolis, proceeded within a time to fall into his pupillage, a fact attested to by Lucian. All, known about the life of Epictetus is due to Arrian, in that Arrian left an Encheiridion of Epictetus' philosophy. After Epirus he went to Athens, while there he became known as the young Xenophon as a consequence of the similarity of his relation to Epictetus as Xenophon had to Socrates. For a period, some time about 126 AD, he was a friend of the emperor Hadrian, who appointed him to the Senate, he was appointed to the position consul suffectus around 130 AD, in 132 AD, he was made prefect or legate of Cappadocia by Hadrian, a service he continued for six years. When he retired, Arrian went to live in Athens, where he became archon sometime during 145 or 146, he died in the reign of Marcus Aurelius. Arrian referred to himself as the second Xenophon, on account of his reputation and the esteem in which he was held.
Lucian stated him to be: a Roman of the first rank with a life-long attachment to learning Τhis quality is identified as paideia, the quality considered to be of one, known as an educated and learned personage, i.e. one, esteemed and important. There are eight extant works; the Indica and the Anabasis are the only works intact. His entire remaining oeuvre is known as FGrH 156 to designate those collected fragments; this work is the earliest extant work, dated with any confidence. It is a writing addressed to the Emperor Hadrian. Arrian was a pupil of Epictetus around 108 AD, according to his own account, he was moved to publish his notes of Epictetus' lectures, which are known as Discourses of Epictetus, by their unauthorized dissemination. According to George Long, Arrian noted from Epictetus' lectures for his private use and some time made of these, the Discourses. Photius states that Arrian produced two books the Discourses; the Discourses are known as Diatribai and are a verbatim recording of Epictetus' lectures.
The Enchiridion is a short compendium of all Epictetus' philosophical principles. It is known as a handbook, A Mehl considers the Enchiridion to have been a vade mecum for Arrian; the Enchiridion is a summary of the Discourses. JB Stockdale considered that Arrian wrote eight books of which four were lost by the Middle Ages and the remaining ones became the Discourses. In a comparison of the contents of the Enchiridion with the Discourses, it is apparent that the former contains material not present within the latter, suggesting an original lost source for the Enchiridion. Friendly conversations with Epictetus is a 12 book work mentioned by Photius in his Bibliotheca, of which only fragments remain; the Anabasis of Alexander comprises seven books. Arrian used Xenophon's account of the March of Cyrus as the basis for this work. History of the Diadochi or Events after Alexander is a work of ten books. Three extant fragments are the Vatican Palimpsest, PSI 12.1284, the Gothenburg palimpsest, these stemming from Photius.
The writing is about the successors of Alexander the Great, circa 323 – 321 or 319. A lost work of seventeen books, fragments of Parthica were maintained by the Suda and Stephen of Byzantium; the work survives only in adaptations made by Photius and Syncellus. Translated, the title is History of the Parthians. Arrian's aim in the work was to set forth events of the Parthian war of Trajan; the writing mentioned that the Parthians trace their origins to Artaxerxes II. A work of eight books, Bibliotheca states. A work translated a Nicodemian script. Indica is a work on a variety of things pertaining to India, the voyage of Nearchus in the Persian Gulf; the first part of Indica was based on the work of the same name of Megasthenes, the second part based on a journal written by Nearchus. Written 136/137 AD, Techne Taktike is a treatise on Roman cavalry and military tactics, includes information on the nature and disciplin
The Greyhound is a breed of dog, a sighthound, bred for coursing game and Greyhound racing. Since the rise in large-scale adoption of retired racing Greyhounds, the breed has seen a resurgence in popularity as a family pet. According to Merriam-Webster, a Greyhound is "any of a breed of tall slender graceful smooth-coated dogs characterized by swiftness and keen sight", as well as "any of several related dogs," such as the Italian Greyhound, it is a gentle and intelligent breed whose combination of long, powerful legs, deep chest, flexible spine and slim build allows it to reach average race speeds exceeding 64 kilometres per hour. The Greyhound can reach a full speed of 70 kilometres per hour within 30 metres, or six strides from the boxes, traveling at 20 metres per second for the first 250 metres of a race. Males are 71 to 76 centimetres tall at the withers, weigh on average 27 to 40 kilograms. Females tend to be smaller, with shoulder heights ranging from 68 to 71 centimetres and weights from less than 27 to 34 kilograms.
Greyhounds have short fur, easy to maintain. There are thirty recognized color forms, of which variations of white, fawn, black and blue can appear uniquely or in combination. Greyhounds are dolichocephalic, with a skull, long in comparison to its breadth, an elongated muzzle. Greyhounds are affectionate with their own pack, they are docile, easy-going, calm. Greyhounds wear muzzles during racing, which can lead some to believe they are aggressive dogs, but this is not true. Muzzles are worn to prevent injuries resulting from dogs nipping one another during or after a race, when the'hare' has disappeared out of sight and the dogs are no longer racing but remain excited. Contrary to popular belief, adult Greyhounds do not need extended periods of daily exercise, as they are bred for sprinting rather than endurance. Greyhound puppies that have not been taught how to utilize their energy, can be hyperactive and destructive if not given an outlet, therefore require more experienced handlers. Greyhound owners and adoption groups consider Greyhounds wonderful pets.
Greyhounds are quiet and loyal to owners. They are loving, enjoy the company of their humans and other dogs. Whether a Greyhound will enjoy the company of other small animals, such as cats, depends on the individual dog's personality. Greyhounds will chase small animals. Many owners describe their Greyhounds as "45-mile-per-hour couch potatoes". Greyhounds live most as pets in quiet environments, they do well in families with children, as long as the children are taught to treat the dog properly with politeness and appropriate respect. Greyhounds have a sensitive nature, gentle commands work best as training methods. A Greyhound may bark. A common misconception regarding Greyhounds is that they are hyperactive; this is not the case with retired racing Greyhounds. Greyhounds can live comfortably as apartment dogs, as they do not require much space and sleep 18 hours per day. Due to their calm temperament, Greyhounds can make better "apartment dogs" than smaller, more active breeds. Many Greyhound adoption groups recommend that owners keep their Greyhounds on a leash whenever outdoors, except in enclosed areas.
This is due to their prey-drive, their speed, the assertion that Greyhounds have no road sense. In some jurisdictions, it is illegal for Greyhounds to be allowed off-leash in off-leash dog parks. Due to their size and strength, adoption groups recommend that fences be between 4 and 6 feet tall, to prevent Greyhounds from jumping over them; the original primary use of Greyhounds, both in the British Isles and on the Continent of Europe, was in the coursing of deer. They specialized in competition hare coursing; some Greyhounds are still used for coursing, although artificial lure sports like lure coursing and racing are far more common and popular. Many leading 300- to 550-yard sprinters have bloodlines traceable back through Irish sires, within a few generations of racers that won events such as the Irish Coursing Derby or the Irish Cup; until the early twentieth century, Greyhounds were principally bred and trained for hunting and coursing. During the 1920s, modern greyhound racing was introduced into the United States, Northern Ireland and the Republic of Ireland.
Australia has a significant racing culture. Aside from professional racing, many Greyhounds enjoy success on the amateur race track. Organizations like the Large Gazehound Racing Association and the National Oval Track Racing Association provide opportunities for Greyhounds and other sighthound breeds to compete in amateur racing events all over the United States; the Greyhound has, since its first appearance as a hunting type and breed, enjoyed a specific degree of fame and definition in Western literature and art as the most elegant or noble companion and hunter of the canine world. In modern times, the professional racing industry, with its large numbers of track-bred greyhounds, as well as international adoption programs aimed at re-homing dogs has redefined the breed as a sporting
The United States of America known as the United States or America, is a country composed of 50 states, a federal district, five major self-governing territories, various possessions. At 3.8 million square miles, the United States is the world's third or fourth largest country by total area and is smaller than the entire continent of Europe's 3.9 million square miles. With a population of over 327 million people, the U. S. is the third most populous country. The capital is Washington, D. C. and the largest city by population is New York City. Forty-eight states and the capital's federal district are contiguous in North America between Canada and Mexico; the State of Alaska is in the northwest corner of North America, bordered by Canada to the east and across the Bering Strait from Russia to the west. The State of Hawaii is an archipelago in the mid-Pacific Ocean; the U. S. territories are scattered about the Pacific Ocean and the Caribbean Sea, stretching across nine official time zones. The diverse geography and wildlife of the United States make it one of the world's 17 megadiverse countries.
Paleo-Indians migrated from Siberia to the North American mainland at least 12,000 years ago. European colonization began in the 16th century; the United States emerged from the thirteen British colonies established along the East Coast. Numerous disputes between Great Britain and the colonies following the French and Indian War led to the American Revolution, which began in 1775, the subsequent Declaration of Independence in 1776; the war ended in 1783 with the United States becoming the first country to gain independence from a European power. The current constitution was adopted in 1788, with the first ten amendments, collectively named the Bill of Rights, being ratified in 1791 to guarantee many fundamental civil liberties; the United States embarked on a vigorous expansion across North America throughout the 19th century, acquiring new territories, displacing Native American tribes, admitting new states until it spanned the continent by 1848. During the second half of the 19th century, the Civil War led to the abolition of slavery.
By the end of the century, the United States had extended into the Pacific Ocean, its economy, driven in large part by the Industrial Revolution, began to soar. The Spanish–American War and World War I confirmed the country's status as a global military power; the United States emerged from World War II as a global superpower, the first country to develop nuclear weapons, the only country to use them in warfare, a permanent member of the United Nations Security Council. Sweeping civil rights legislation, notably the Civil Rights Act of 1964, the Voting Rights Act of 1965 and the Fair Housing Act of 1968, outlawed discrimination based on race or color. During the Cold War, the United States and the Soviet Union competed in the Space Race, culminating with the 1969 U. S. Moon landing; the end of the Cold War and the collapse of the Soviet Union in 1991 left the United States as the world's sole superpower. The United States is the world's oldest surviving federation, it is a representative democracy.
The United States is a founding member of the United Nations, World Bank, International Monetary Fund, Organization of American States, other international organizations. The United States is a developed country, with the world's largest economy by nominal GDP and second-largest economy by PPP, accounting for a quarter of global GDP; the U. S. economy is post-industrial, characterized by the dominance of services and knowledge-based activities, although the manufacturing sector remains the second-largest in the world. The United States is the world's largest importer and the second largest exporter of goods, by value. Although its population is only 4.3% of the world total, the U. S. holds 31% of the total wealth in the world, the largest share of global wealth concentrated in a single country. Despite wide income and wealth disparities, the United States continues to rank high in measures of socioeconomic performance, including average wage, human development, per capita GDP, worker productivity.
The United States is the foremost military power in the world, making up a third of global military spending, is a leading political and scientific force internationally. In 1507, the German cartographer Martin Waldseemüller produced a world map on which he named the lands of the Western Hemisphere America in honor of the Italian explorer and cartographer Amerigo Vespucci; the first documentary evidence of the phrase "United States of America" is from a letter dated January 2, 1776, written by Stephen Moylan, Esq. to George Washington's aide-de-camp and Muster-Master General of the Continental Army, Lt. Col. Joseph Reed. Moylan expressed his wish to go "with full and ample powers from the United States of America to Spain" to seek assistance in the revolutionary war effort; the first known publication of the phrase "United States of America" was in an anonymous essay in The Virginia Gazette newspaper in Williamsburg, Virginia, on April 6, 1776. The second draft of the Articles of Confederation, prepared by John Dickinson and completed by June 17, 1776, at the latest, declared "The name of this Confederation shall be the'United States of America'".
The final version of the Articles sent to the states for ratification in late 1777 contains the sentence "The Stile of this Confederacy shall be'The United States of America'". In June 1776, Thomas Jefferson wrote the phrase "UNITED STATES OF AMERICA" in all capitalized letters in the headline of his "original Rough draught" of the Declaration of Independence; this draft of the document did not surface unti
Lure coursing is a sport for dogs that involves chasing a mechanically operated lure. Competition is limited to dogs of purebred sighthound breeds, although the AKC has a pass/fail trial for all breeds called the Coursing Ability Test. In lure coursing, dogs chase an artificial lure across a field, following a pattern, meant to simulate live coursing. A typical lure course in the United States is between 1,000 yards long. In Europe, as well as the rest of the world, the course length can be over 1000 meters, incorporates some obstacles or jumps; the course must have a minimum number of turns in order to simulate prey changing direction in a chase. The fields can be fenced or not. If a dog is lure focused they will follow the lure from start to finish and not run off course. Dogs with some considerable lure experience, termed "lure-wise", may try to anticipate or "cheat" by attempting to cut off the lure instead of trying to capture the lure using follow and agility. Sighthounds have no need to be trained or enticed to chase the lure since the desire to chase is instinctual.
Some breeds do, require lure play at a early age to encourage them to follow an artificial object with enthusiasm. Dogs must be at least one year old to compete. Dogs at an earlier age do require a moderate but essential introduction to the artificial chase to: stimulate their normal mental and physical development, to prepare and improve their capacity to perform physically with enthusiasm without hurting themselves - as is the case with the mutual, voluntary athletic play of littermates. In American Sighthound Field Association competitions, a dog must be Certified in order to compete in the Open category of the breed. To certify, a dog must run clean with another dog of similar running style and be certified by a qualified ASFA judge. Dogs used for certification do not have to be certified themselves, nor do they have to be a sighthound, judges can certify two or three hounds at the same time. In American Kennel Club coursing, a new rule was passed in early 2010, making the certification process similar to the ASFA certification process.
A dog must run cleanly against another dog of similar running style in order to earn a QC. Dogs can still earn their JC title by running a minimum of 600 yards with four turns twice, in two separate trials, under two different qualified AKC judges; the dogs run alone, once they complete both runs, they earn a Junior Courser title. The JC title, however, no longer allows them to compete against other dogs. In Europe, competing dogs need a coursing licence or racing licence for official national and international lure coursing trials, obtained through a racing or coursing club, are principally run in braces only of the same breed, or run solo. Dogs are coursed by breed based on the number of dogs available for the run. Dogs can run alone if there are no other dogs of the same breed entered, but in AKC their scores will not qualify towards a title unless they defeat a hound in a Best Of Breed run or win Best In Field. Running order is determined by a random draw within their breed, is not based on size or comparable ability.
Dogs can compete in field champion stake, or veteran stake. Each dog runs twice during the trial; the first run is the "preliminary". After all preliminaries have been run, the course is reversed for the second run, called "finals". Once all preliminaries and finals have been run, Best of Breed is determined for each breed by stakes run-off or by forfeit. All placements must forfeit. After the Best of Breed runs, the top dogs from each breed compete for Best In Field to determine the best hound for the trial; some clubs opt to provide a Best in Event which brings Best of Breed dogs from multiple days to run off. In AKC, rules regarding breeds that may not compete in Best In Field are updated periodically, based on recommendations of the breed club, provisional or limited breeds may not run in Best In Field. In American Sighthound Field Association trials, hounds receive a numerical score based on speed, endurance and follow for a maximum score of 100 points. "Follow" means in pursuit of the lure, not the other dogs.
Judges will deduct a pre-slip penalty of up to 10 points for the early release of a hound in a course. Judges can assess up to 10 points penalty for a course delay. Judges can excuse a hound from competition for failing to run, being unfit, coursing another hound instead of the lure, hound or handler interference, or excessive course delay. Hounds can be dismissed for interfering with another hound. Hounds may be disqualified for being the aggressor in a fight on the field. In American Kennel Club trials, hounds are judged for overall ability, speed and endurance for a maximum score of 50 points; the AKC offers lure coursing titles for all breeds through the Coursing Ability Test. This program is fail. To pass, the dog must complete a 600-yard course with enthusiasm. In international lure coursing trials in Europe, dogs are ju
