Africanized bees are characterized by their aggressiveness in establishing new hives and in their vigorous defensive behavior, attacking perceived threats to their hive, including people. Over the decades, hundreds of deaths in the Americas have been attributed to Africanized bees, many deaths resulting from multiple bee stings. This defensiveness has earned them the nickname "killer bees", the aptness of which is debated. Allergic reactions to bee venom from European honeybees also kills people, and it is difficult to estimate how many more people may ...

As of 2002, Africanized honeybees had spread from Brazil south to northern Argentina and north to South and Central America, México, Texas, Arizona, New Mexico, and southern California. Their expansion stopped for a time at eastern Texas, possibly due to the large number of European bee beekeepers in the area. However, discoveries of the bees in southern Louisiana indicate this species of bees has penetrated this barrier, or have come as a swarm aboard a ship. In June 2005, it was discovered that the bees had penetrated the border of Texas ...

Africanized bee - In the European Bee intentional selection. The chief difference between the European races or subspecies of bees kept by American beekeepers and the Africanized stock is attributable to selective breeding. The most common race used in North America today is the Italian bee, Apis mellifera ligustica, which has been used for several thousand years. Beekeepers have tended to eliminate the fierce strains as they did, and the entire race of bees has thus been gentled by selective breeding. < ...

Africanized bee - The lore. In Brazil, the Afrucab bee and its hybrid are known as the Assassin Bee, for its supposed habits in taking over an existing colony of European bees. According to this lore, their queen waits outside while several worker bees infiltrate the hive by bringing in food, where they will then locate and kill the queen. The new queen will then enter and take over the hive. < ...

Africanized bee - Use caution with power mowers. Bees are sensitive to low frequency vibrations and so an engine driven lawn mower may elicit a defense response from a hive or swarm. Africanized bee - Walk with care in clover and near picnic sites. Take care not to walk barefoot on lawns containing blooming clover, which attracts foraging bees. Meat eating wasps can be attracted to food scraps near a picnic site and usually forage close to the ground as they seek out downed insects s ...

The Critic - Jay Sherman. "New York's third most popular early-morning cable-TV film critic." His catchphrases include his exclamation of surprise ("Hotchie motchie!"), his common putdown of sub-par films ("It stinks!") and his distinctive cough. He is known for his surly and sarcastic putdowns of the majority of films he reviewed. He often uses the "Shermometer" to measure the films he reviews, or a list of diseases he'd rather have than see a movie. Most of his dislike for films comes from a love for film that ...

SADS, or sudden arrhythmia death syndrome, is a term used to describe sudden death due to cardiac arrest brought on by an arrhythmia. The most common cause of sudden death in the US is coronary artery disease. Approximately 300,000 people die suddenly of this cause every year in the US. SADS can also occur from other causes. Tragically there are many inherited condictions and heart diseases that can affect young people that can cause sudden death. Many of these vict ...

Dog, in common usage, refers to the domestic dog, Canis lupus familiaris (originally classified as Canis familiaris by Linnaeus in 1758, but reclassified as a subspecies of the wolf, Canis lupus, by the Smithsonian Institution and the American Society of Mammalogists in 1993). The word is sometimes used to refer collectively to any mammal belonging to the family Canidae (as in "the dog family"), such as wolves, foxes and coyotes. Dog is also a term used by breeders to specifically denote a male ...

Presently, there is academic discussion as to whether domestic dogs are omnivores or carnivores. The classification in the Order Carnivora does not necessarily mean that a dog's diet must be restricted to meat. Unlike an obligate carnivore, such as a cat, a dog is not dependent on meat protein in order to fulfill its dietary requirements. Dogs are able to healthily digest a variety of foods including vegetables and grains, and in fact can consume a large proportion of these in its diet. Wild canines not only eat available plants to obtain ke ...

Among professional breeders, dogs are only allowed to mate for a specific purpose. Sometimes dogs are bred to create puppies to sell, or sometimes to carry on an award-winning purebred line. Breeders who do this are usually experienced in this process. Dog breeders have access to records which allow them to accurately guess which characteristics will "breed true" in a particular dog. Dog breeders also have accurate information on the complexities of the reproductive process for the breed of dog that they are accustomed to handling. Dog owners may accidently allow their pets to breed without regard to bloodlines. See also:

Modern dog breeds show more variation in size, appearance, and behavior than any other domestic animal. Within the range of extremes, dogs generally share attributes with their wild ancestors, the wolves. Dogs are predators and scavengers, possessing sharp teeth and strong jaws for attacking, holding, and tearing their food. Dog - Sight.

All dogs have a tremendous capacity to learn complex social behavior and to interpret varied body language and sounds, and, like many predators, can react to and learn from novel situations. The requirements of coordinating complex social behavior requires that canines have the ability to sense and deliver a wide variety of cues via body language, more so than for even humans, who can use language for the same purpose. Physiologically, this correlates with such features as a large number of nerves innervating the facial muscles of dogs, allo ...

Molecular systematics indicate that the domestic dog (Canis familiaris) descends from one or more populations of wild wolves (Canis lupus). As reflected in the nomenclature, dogs are a subspecies of wolf and are thus still able to interbreed. The relationship between man and canine has deep roots. Wolf remains have been found in association with hominid remains dating from 400,000 years ago. Converging archaeological and genetic evidence indicate a time of domestication in the late Upper Paleolithic close to the Pleistoc ...

There are numerous dog breeds, over 800 being recognized by various kennel clubs worldwide. As all dog breeds have been derived from mixed-breed dog populations, the term "purebred" has meaning only with respect to a certain number of generations. Many dogs, especially outside the United States and Western Europe, belong to no recognized breed. A few basic breed types have evolved gradually during the domesticated dog's relationship with man over the last 10,000 or more years, but most modern breeds are of relatively recent derivation ...

Medical usage sometimes distinguishes a disease, which has a known specific cause or causes (called its etiology), from a syndrome, which is a collection of signs or symptoms that occur together. However, many conditions have been identified, yet continue to be referred to as "syndromes". Furthermore, numerous conditions of unknown etiology are referred to as "diseases" in many contexts. Illness, although often used to mean disease, can also refer to a person's perception of their health, regardless of whether the ...
