Environmental Science – P1DB Indeed, there are many species in the United States. Some of them are native to the country, while some of them are imported. Many readers ask questions about how, when, and why were some species imported to the U.S., where do they occur at the moment, was their introduction intended, how it occurred, why the species are so invasive, what are the ecological effects these species have had on local plant and animal population, therefore, the article was written to answer all these questions about two the most interesting species, the fire ant, and the killer bees. Africanized Honey Bees (AHB), also known as Africanized bees or killer bees are descendants of the southern African bees that were imported in 1956 by the scientists from Brazil. The killer bees were imported, as the scientists were making an effort to breed a honey bee better adapted to the South American tropic climate. Although it seems that everything was under control, some of the southern African bees managed to escape quarantine in 1957, and then they began breeding with the local Brazilian honey bees. Soon their population was so huge that they extended their range throughout Central and South America at a rate over two hundred miles per year. In the last few decades, the killer bees began to invade even North America.
Africanized Honey Bees (AHB) got their name, the killer bees, as they viciously attack animals and people, who unreasonably enter their territory. The bees’ attack often results in very serious injury or even death. Since they were introduced into the country, they have killed over 1,000 people, with the victims getting 10 times as many stings than from the European bees. Africanized Honey Bees attack dark things, are sensitive to the odors (both unpleasant and pleasant), therefore it is strongly recommended to avoid the contact with them, and, obviously, to contact local beekeeper or a pest control company to solve the problem (Africanized Honey Bees, 2008), if there are any signs of Africanized Honey Bees taking up their residence. What concerns fire ants, there are some species native to the U.S., while some of them are really imported. There is an assumption that fire ants were imported from South America with the soil of potted plants or as the ballast on the ships that were arriving to Alabama, and Mobile. The black Imported fire ant (S.
The Essay on Killer Whales
Killer Whale, largest member of the dolphin family. Killer whales occur in more parts of the world than probably any other cetacean (see Whale). They occur in all oceans, both in the open ocean and close to shore, but are more common in the colder, more productive waters of both hemispheres than in the Tropics. Resident populations may cover an area of several hundred square kilometers. Transient ...
richteri) was brought from Argentina. The red imported fire ant (S. invicta) first arrived from Brazil (Argentina or Paraguay) in the 1920s or even before (Fire Ant – Factoids, 2008).
The Red Imported Fire Ant is usually associated with disturbed habitats, and is usually abundant in the lawns, old fields, roadsides, pastures, and sunny areas. As far as it also inhabits the agricultural fields, it create problems in planting and harvesting crops. The Red Imported Fire Ant feeds on wheat, corn and sorgham seed, soybean and dry cotton seeds.
Apart from that, the ant is very toxic and quickly spread through a habitat. Nowadays, the Red Imported Fire Ant can be found throughout most of the west into California and Texas, and the southeastern United States (over 300,000,000 acres in the United States).
The ant is very dangerous, as it quickly does latch onto the human flesh with its barbed mandibles, and then it stings repeatedly, pivoting in tiny circles until you, the victim can repel them or dies. The venom is very painful, and causes tiny blisters or white pustules that persist for days if left untreated or for weeks if scratched or infected and may leave permanent scars (Fire Ant – Factoids, 2008).

The Term Paper on Fire Attack: Offensive vs. Defensive
Structural firefighting can be very dangerous and can put the lives of firefighters in situations were their decision can end up being very detrimental. History has proven when the wrong choices were made, and lives and properties were lost. From past structural events the choice of choosing the wrong attack could end up being in the papers and going to funerals for firefighters. That’s why ...
