Black footed ferret
Don’t take our word for it - see why 10 million students trust us with their essay needs.
Only a small handful of endangered species have been reunited to there respective populations in the last few decades. The black footed ferret (also recognized as its scientific name Mustela Nigripes) was thought to be one of the most endangered animals in the United States and completely wiped out from Canada.
The black footed ferrets were declared extinct in 1974, in 1981 a miracle happened when aferret was discovered in Meeteetsee, Wyoming when John and Lucille Hogg’s ranch dog killed a black footed ferret and carried the dead animal home; they took the corpse to a knowledgeable taxidermist Larry LaFranchie. This became such great opportunity to save the species. A terrible disease in 1985 attacked the small ferret population, and a lot of the remaining animals were taken into captivity in a desperate effort to save what was left. Captive breeding was initiated soon after, and a reintroduction program began in 1991.
In this paper, I will discuss the threats, habitat, and habitat loss of the black footed ferret, the importance of agriculture and how it affects the black footed ferret today, and how prairie dog colonies affect where the black footed ferret lives. I will discuss how they reproduce, their behaviors, and how they are important to an ecosystem.
The ferrets are obligatory predators on the prairie dogs. This is known as a specialized predator because they only eat prairie dogs. The ferrets prey on prairie dogs and take advantage over their burrows for shelter and denning. The ferret takes control of the burrow by strangling them and eating them. Black footed ferrets eat a lot of prairie dogs; a family of 4 ferrets eat up to 250 prairie dogs per year. The prairie dogs back in the 20th century were persecuted as agricult...

...gue by fleas, or by eating dead prairie dogs that have been infected and died with it in there system. Through this encounter of this disease, the US Army and the US Geological Survey had concocted a vaccine that has been proven to be effective at preventing this disease. They inject this vaccine into the burrows, approximately 3 week later it provides a lifelong immunity towards the plague. Captive ferrets are injected before they are released into the wild, and efforts have been made to inject the wild ferrets, but it is intense and very time consuming to attempt this.

Some captive species even have problematic changes in reproduction such as not be able to reproduce anymore (Lynn 1817). These changes in behavior and high cost are a major factor in whether these programs are sophisticated and whether the animals can be reintroduced into the wild and if it would benefit their
The maned wolf is omnivorous and is a secondary consumer alike the Coyote and Darwin's fox. It has a similar diet to the coyote’s, since it feeds on small and medium sized mammals such as rodents, birds, fish and rabbits. Unlike the coyote and Darwin's fox, the maned wolf does not have any specific enemies or predators, but it may be attacked or even killed by feral dogs.

Edgar Allan Poe was born January 19, 1809. Many consider him to be the master of mystery and horror. He only lived until he was forty, and during that time he endured a lot of hardships. For one, every woman he ever cared for ended up dead, usually by the dreaded tuberculosis. That included his wife Virginia. The men in his life who were supposed to be there to guide him, well, they were not there. I think that helped him write a lot of his dark and macabre stories. His most famous work is The Raven, a narrative poem that was first published in January 1845. He also wrote other highly regarded short stories such as, The Murders in the Rue Morgue, The Tell- Tale Heart, and The Black Cat. I will be doing my review on the latter of the three.

The plague was spread by fleas, which were not effected by the disease. Fleas first infected the rats, which lived off garbage and sewage. The rats then spread the infection to the humans. Rats were a common sight in the cities, due to the poor sanitary conditions, so no one suspected them (www.tartans.com). In the winter the plague seemed to disappear, but only because fleas were dormant then. Each spring, the plague attacked again, killing new victims (www.byu.edu). The effects of the plague were devastating. After just five years, twenty-five million people were dead - one third of Europe's population. Once people were infected they infected others very rapidly. As a result, in order to avoid the disease, many fled to the countryside where the lower population density helped to decrease the speed at which the disease spread (www.tartans.com). From a person's time of infection to his or her death was less than one week (www.home.nycap.rr.com). The plague became known as "The Black Death" because of the discoloration of the skin and black enlarged lymph nodes that appeared on the second day of contracting the disease. The term "The Black Death" was not invented until after 1800. Contemporaries called it "the pestilence" (Cantor 7).
Estimates are that at the turn of the twentieth century over two million wild horses roamed free in the western United States. However, having no protection from their primary predator, man, by the 1970’s there numbers had dwindled to less than thirty thousand. In 1971, after a massive public uproar, Congress by a unanimous vote enacted the “Wild Free-Roaming Horse and Burro Act” (Act) that characterizes wild horses and burros as national treasures and provides for their protection.
It was a bubonic plague that came from Asia and spread by black rats infested with fleas. The plague spread like a wildfire because people who lived in high populated areas were living very close to each other and had no idea what was the cause of the disease or how to cure it. The signs of the “inevitable death” where blood from the nose, fever, aching and swellings big as an “apple” in the groin or under the armpits. From there the disease spread through the body in different directions and soon after it changed into black spots that appeared on the arms and thighs. Due to the lack of medical knowledge, no doctors manage to find a remedy. Furthermore a large number of people without any kind of medical experience tried to help the sick but most of them failed “...there was now a multitude both of men and of women who practiced without having received the slightest tincture of medical science - and, being in ignorance of its source, failed to apply the proper remedies…” (Boccaccio). The plague was so deadly that it was enough for a person to get infected by only touching the close of the
Unfortunately, besides the animal being such a stately and scientifically contributing creature, it has been endangered by various factors.
“Rat control and watching for the disease in the wild rodent population are the main measures used” ("Plague") to help prevent the spread of the Bubonic Plague today. With this prevention being announced throughout the science fields and communities, less and less people are encountering this deadly disease. Although watching and being careful not to encounter infected rodents has helped, the disease can also be prevented with a vaccine. Normally this vaccine is only administered to people who work or live in areas with large populations of rodents and wild animals that could possibly have the infectious disease. This is due to the fact that scientists are still currently unaware of how effective the vaccine is and the different symptoms that can occur from getting the vaccine. The vaccine is also not administered often because of the lack of people around wild rodents, but “[f]urthermore, these vaccines are no longer being manufactured in the U.S.” (Meysick). Without the United States producing the ingredients needed to manufacture the specialized antiserum, the people that are employed in areas dealing with wild rodents still have the possibility of acquiring the disease. A probable reason to why the United States does not produce this antiseptic anymore can be that the price to
