Restoration of the Red Wolf; preventing their extinction once more Ref: (4) USFW (US Fish and Wildlife Service) and IUCN status of the Red wolf The red wolf is listed as endangered under the U. S. Endangered Species Act (ESA) (United States Public Law No. 93-205; United States Code Title 16 Section 1531 et seq.). Wild red wolves inhabiting the north eastern North Carolina (NENC), USA recovery area and a single island propagation site (St. Vincent NWR, Florida) are designated as experimental non-essential populations under Section 10(j) of the ESA. The IUCN Red List of Threatened Species lists the red wolf’s status as critically endangered. Problem: The red wolf is one of the most endangered wild canids in the world, once common throughout south eastern United States, the red wolf population was severely reduced due to intensive predator control programs and loss of habitat. A few remaining wolves were found on the Gulf coast of Texas and Louisiana, at this point in the 1970’s, the entire population was believed to be fewer than 100. The red wolf announced to the world to that it was officially extinct in 1973, with just a few red wolves in captivity. The problem now being addressed is how to prevent the red wolf being extinct again as it is now on the endangered species list. Genetic Diversity within a species- Red wolf: Each and every individual organism has unique combination of alleles. The greater the variation of alleles in a species, the less likely the species is to die out as they’re all different and so react differently to threats in terms of infection and can defend themselves in numerous ways. This means that even if there was an outbreak of disease, because the variation of genes and combinations of al... ... middle of paper ... ...6) Wikipedia Available at: http://en.wikipedia.org/wiki/Red_wolf Accessed: 19/02/2014 2), 7), 5), 3), Ref: (December 2006) US Fish and Wildlife Service Available at: http://www.fws.gov/southeast/pubs/alwolf.pdf Accessed: 19/02/2014 6), 8), 9) Ref: http://redwolves.com/rwc/downloads/other/rw_biology_status.pdf 2) Ref:http://redwolfssp.org/newsite/studbooks/2012_red_wolf_studbook.pdf 3) Red Wolf (Canis rufus) Recovery: A Review with Suggestions for Future Research- Journal (13 August 2013) Author: Joseph W.

The history behind the extirpation of the grey wolf in the United States dates back to the very first European settlers that colonized eastern North America in the late 16th century. The killing of gray wolves was done primarily out of fear in an attempt to protect livestock, and, in some cases, to protect human life within the colonies. As more settlers expanded West, the practice of killing wolves was considerably increased to protect livestock that included cows, pigs, and chickens. As waves of European settlers expanded westward, they began to deplete the deer, moose, and elk populations. The gray wolves food source continual depletion gave rise to wolf populations actively targeting the settler’s livestock, causing great financial loss. The fiscal loss of livestock became such an issue to wealthy ranchers and settlers that they began to offer cash rewards for wolf pelts. This practice gave birth to a lucrative cottage industry of professional hunters and trappers. As the wolves began to move further West, and into Wyoming, they began to diminish the elk and moose population. To respond to this threat, Congress approved funding in 1914, to eliminate the native gray wolves from
The gray wolf, Canis lupus, on Isle Royal is a small ever fluctuating population. On the endangered species list since 1978, the gray wolf has recently been taken off the endangere...
Gray Wolf Optimization Gray wolf optimization is presented in the following subsections based on the work in [13]. 1) Inspiration: Grey wolves are considered as apex predators, meaning that they are at the top of the food chain. Grey wolves mostly prefer to live in a pack. The group size is 512 on average. They have a very strict social dominant hierarchy.
During 70 years of absence from the Rockies, the Grey Wolf had been protected under the Endangered Species Act that was passed in 1973. Since the wolf is under the protection of Endangered Species Act a person could be punished with up to a $100,000 fine and up to 1 year in jail for killing a wolf. Back in the 1850's there was a major population increase of the wolves in America, this was due to settlers moving west. These settlers killed more than 80 million bison, the wolves started to scavenge on the carcasses left behind.
For nearly 100 years, the forests of the State of Maine have seen close to none eastern timber wolves. The animals that once roamed the woods are gone and may never return. This is why in 1969 the eastern timber wolf was placed on the endangered species list. With great efforts, maybe someday, the eastern timber wolf may inhabit the woods of Maine again.
...y white fur for fur that cost a lot of money. Some people like to sell their teeth for money or make jewelry. Mostly just for the thrill of it. Also to sell the whole wolf for money or cut off pieces of the wolf like head, ears, paws, and tail as a award for that they killed one. So because of all the stuff that people are doing to kill these wolves are making all them all disappear. There are less ad less. There are not in all 50 states as they use to be, they are reduced down to 7 states and Canada, that is how serious there case is now a day.
Canis Lupus, the Latin term for the “North American Wolf”. A meat eating mammal with the capability of weighing up to 180 pounds and reaching a height of sixty-three inches, the wolf is easily the largest member of the canine family. Over 500,000 wolves once lived in harmony, roaming the Northern Americas alongside the Native American tribes and the rest of the ecosystem. Wolves live in packs, a pack essentially being a family. While the average size of a pack is six to ten, the largest confirmed pack recorded in North America can be found in Yellowstone National Park where the “Druid Pack” numbers thirty-seven strong and counting. There have been alleged reports of a pack that attacked a small Russian town killing thirty horses in just four days. This pack numbered up to almost 400 members. Animal experts remain suspicious due to the fact that this number is almost fifteen times the size of an average sized pack. Wolves heavily rely on their pack. Every member of the pack has a specific job that benefits the pack, without the pack, death would be almost imminent. The pack is set up as a hierarchy, with an alpha male and an alpha female. The alphas get the best of everything, the best part of the kill, the best sleeping spot, and the breeding rights. When hunting, one member will scout ahead and will determine the weakest member of the herd. Once determined, the rest of the pack will chase the animal down and either takes it down on the run or chase it until it tires out. Unlike many predators in the animal kingdom, wolves eat their prey alive. While wolves are known for their spine tingling howls, the howl is not the only way they communicate. “Wolf Language” so to speak, consists of many grunts, snarls, growls, yips, and whines....
With this new law, more breeds of wolves and bears are likely to become endangered and even extinct. This law protects hunters’ inhumane strategies to slaughter
The TED talk addressed the issue of infectious disease and the ways in which disease is spread using the examples of cholera and malaria. The speaker Paul Ewald discussed the ways in which humans may have the ability to reduce their exposure and spread of infectious disease through applying the theory of evolution by natural selection. This spread of disease poses a threat to humans as the bacteria that cause the disease evolves with humans and become resistant to the medical interventions. The speaker addressed some key issues and posed some important solutions towards the betterment of human lives. The field of biological science studies when it comes to human’s works towards understanding the evolution of humans and the threats to the survival of our species. Understanding the evolution of disease is important in creating ways to protect humans against these diseases and properly treating those infected. The 21st century has been seen some successful cases in which science has been successful in the irradiated disease through the use of research and development of antibiotics but there are still diseases that plague countries especially in the developing world. Lack of information in regards to diseases and the effects of disease on humans can be critical to human survival if diseases evolve beyond our control which can lead to a pandemic.

When the reintroduction of wolves began in the state of Wisconsin, a goal of 350 wolves was set, and this number was reached successfully in a short amount of time. Once this was reached, however, the population continued to rise dramatically and exponentially, and is now in the upper 600s (Allen). The problems now come down to a few simple questions that have complex answers. Will a regulated hunt get out of control, and a repeat of the past begins? Are the wolves posing any sort of threat in the present? Who or what would a hunt benefit? First, the issue of the past must be addressed. Back in the earlier years of the United States, wolves roamed free, and when farmers moved their livestock into what was then the wolves' territo...
According to the Committee on the Status of Endangered Wildlife in Canada (COSEWIC), black-footed ferrets were initially thought to be extinct (Calgary Zoo). After 1987, however, they are listed as extirpated—extinct in the wild. In the IUCN red list, this species is listed as endangered. Black-footed ferret populations faced a high decline in population during the 1970s, when the population was listed as extinct.
Wolves had live throughout parts of the world for thousands of years before humans just kept rising in population and minimizing the wolves’ population through the expansion of their territories for farm agriculture and industrialization. It is only in the United States where humans completely annihilated wolves; they did this by hunting the wolves down until the last wolf was killed in 1926. However, in 1995, 14 wolves were caught from Canada and release into Yellowstone National Park. This makes it almost 70 years since the wolves have been reintroduced back into Yellowstone National Park (17 July 2009)
The human population has a high susceptibility to the contraction of new diseases and outbreaks of these diseases are of high risk. Diseases in recent times that have broken out into the human population are the H7N9 flu strain and SARS. Despite the risk, outbreaks like H7N9 and SARS have been controlled due to epidemiology and other disease control methods. Outbreaks of disease are not uncommon to the human population as they move to new areas around the world with foreign diseases that the native residents would have developed a resistance to.
Unfortunately, besides the animal being such a stately and scientifically contributing creature, it has been endangered by various factors.
