Throughout the past several decades, the black footed ferret (mustela nigripes) remains at the near top of the endangered species list. These small mammals are one of the most endangered species in North America. The black footed ferret has little visibility compared to other endangered species. With a population of only 370, the black footed ferret’s chances of survival appear slim. Total elimination of the black footed ferret would negatively impact other species in its ecosystem. If awareness of the black footed ferret’s condition increases, the general public can help them by providing donations. The main reasons for endangerment include loss of habit and disease. These factors prevent the black footed ferret from repopulating. By exposing …show more content…
The initial catalyst for the loss of the black footed ferret population was poisoning efforts made in the early 1900s. The target of the poisoning was the prairie dog population, which in turn caused a sharp decline in the black footed ferret population. The most common poisons used by North Dakota residents are zinc phosphide and Rosal. Most people dislike prairie dogs, so they use poison to terminate them. This decline in the prairie dog population in turn affects the black footed ferret population. Other factors that reduce the chances of the black footed ferret’s survival include the conversion of farmland and hunting. (North Dakota Carnivores). The primary reason the black footed ferret is endangered originates from the spread of the plague. According to Oldemeyer, “plague is a flea transmitted disease of rodents caused by the bacterium Yersinia pestis that exists in widespread, discontinuous foci in parts of Africa” (Oldemeyer 28). Specifically, the Bubonic plague has had a lasting effect on rodent populations. An important factor that affects the prairie dog and black footed ferret populations is the density of the host population. The density of the prairie dog population remains more susceptible to the exchange of the plague. The plague moves quickly between colonies with the help of other predators. Fleas primarily transmit the plague to prairie dogs and black footed ferrets. Two main …show more content…
Through the work of scientists and conservation programs, the black footed ferret has made a lot of progress. Over time, the black footed ferret will continue to recover if captive breeding programs and vaccinations continue. The World Wildlife Fund has worked to restore black footed ferret populations. In 2015, fifteen black-footed ferrets were released into prairie dog colonies. After an outbreak of the plague devastated release sites in 1999, the ferret and prairie dog populations dropped significantly. The WWF provided aid in creating plague management, and in 2013 and 2014, 52 black footed ferrets were released onto a reservation (WWF). The loss of the black footed ferret would not have a large global affect, as it only resides in North American grasslands. Its loss would have a large affect locally because of the black footed ferrets’ influence in its habitat. Without the black footed ferret, the prairie dog population would be affected negatively. The WWF states that the black footed ferret “signifies the health of the grassland ecosystem which they depend on to survive” (WWF). The black footed ferret is a necessity to its environment and the species around
Sixty years after the extirpation of wolves in the Northern Rockies and Great Plains of America, biologist and ecologist in Yellowstone National Park reintroduced wolves into a declining ecosystem that once thrived during their presence. The reintroduction brought immense controversy into the West and continues to stir outrage among anti-wolf groups. These anti-wolf supporters argue wolves are ruthless predators that cause destruction to natural environments and livestock. Conversely wolf advocates and scientists suggest that wolves are a keystone species that are essential to the natural regulation of our Western ecosystems. Although pro and anti-wolf advocates can agree that wolves have an effect on livestock, ungulate populations and ecosystems,
Rats acted as vectors as they carried the infected fleas into the cities. One factor that influenced the spread was that in 1350 hygiene was inadequate and often food and faeces were left in the streets this meant that the cities ect was teeming with rats as they had an appropriate food source and habitat. Humans lived alone side rats but since the rats carried the fleas the fleas would bite the people who lived there thus infecting them. The next factor is that the rats began to die of the plague so household pets or other animals started feeding on them thus becoming infected. Since pets were becoming more common they had access to the household.
The bacillus infects people through the bite of infected fleas and rats (“BLACK DEATH”). This was especially prominent in urban and over populated areas (“Ecology and Transmission“). When Plagues strike people and animals alike die horrifically, in turn fleas need to find other sources of food. The people living in poor conditions often get forayed by flea bites, thus infecting them (“Ecology and Transmission“). It was seldom for the Black Death to be spread from person to person.
The Black Death The Black Death: The Medieval black plague that ravaged Europe and killed a third of its population. It was due to the plague which is caused by a bacterium (Yersinia pestis) transmitted to humans from infected rats by the oriental rat flea. “By all accounts, the Black Death spread from France in the summer of 1348 to the port of Weymouth on the southern coast of England, from whence it travelled very rapidly to other ports in both directions along the coast. It progressed up through the Bristol Channel to Bristol before advancing along the Severn to Gloucester.
Feral cat populations have skyrocketed over the last few decades, and no one can quite agree on what to do about it. The overpopulation of feral cats pose a danger to birds and other wildlife, along with some risks to humans given the diseases they could possibly carry. Both sides agree something must be done about the feral cat population, but the debate comes in what should be done. For years the solution to the problem was to simply kill the feral cats, but the use of TNR, trap-neuter-return, is becoming more popular. TNR offers the option to shrink the population of feral cats, without causing the death of thousands of kitties.
The recovery plan for the black-footed ferret (Mustela nigripes) is a collaborative effort between the U.S. Fish and Wildlife Service (USFWS) and the National Black-footed Ferret Conservation Center Office (USFWS, 2013). The species was first listed as endangered in 1967 and “grandfathered” into the Endangered Species Act in 1973 (USFWS, 2013). The black-footed ferrets populations declined because of the close association the ferrets have with the black-tailed prairie dog (C. ludovicianus), Gunnison’s prairie dog (C. gunnisoni), and white-tailed prairie dog (C. leucurus) (USFWS, 2013). The ferret relies on the prairie dogs for food and utilizes the prairie dog’s burrows for shelter. The destruction of habitats through the conversion of prairie land to cropland along with the poisoning of prairie dogs as pests, sylvatic plague and other diseases led to the prairie dog population decline (USFWS, 2013).
In the spring of 1348, the most devastating pandemic in European history infected it’s first victim along the coast of Italy. The Bubonic Plague had established a foothold and would continue to rip its way through Europe for the rest of the 14th century. The Bubonic Plague is a vector borne illness that is transmitted by a flea that is typically found on rats. The plague originated in Eastern Asia, but found its way to Europe along trade routes carried by rats on Genoese ships. The Bubonic Plague was extremely devastating to European society in several ways including: major population destruction, harsh invalid accusations, and compounding medical issues.
Black Plague Outbreak in Western Massachusetts If the Black Plague were to infect the people of Western Massachusetts I would stay in my home. The risk of catching the disease is even greater if you were to travel to different parts of the world. The plague is spread with contamination, with animals, human beings and more. You have the risk of coming in contact with contaminated animals or beings, such as rats and mosquitoes.
A drastic change as we can see that more than half of the Everglades has disappeared. Along with the disappearance of its land and water we see that animals have been effected to. The Everglades is an environmentally diverse location that holds many different habitats and in those habitats lie native, invasive, and endangered species. Throughout this speech you will learn just what exactly is happening to the precious animals of the Everglades.
This essay by Terry Tempest Williams, is describing us first the massacre of the prairie dog that occurred at the Cedar Ridge Golf Course, where over 400 prairie dog where gassed to death. There are 5 species of prairie dog and they are now threatened and might be in extinct in couple of years. The people wanted to exterminate the dogs because they were running the range because they consume a large amount of green grasses and forbs. According to Williams, “Prairie habitat not only for themselves but also for other grassland species. Prairies dog create diversity, destroy them, and you destroy a varied world (p86/87).”

Moreover, zoos always respond to emergencies, such as deadly threats to one or another species, by providing specialists and establishing breeding and treatment programs (Borrell 9). Thereby, both articles express the opinion that zoos are important for conservation purposes as they provide a wide range of specialists and research data. More significantly, they react on emergencies and do their best to protect endangered
Lewis Carroll's "Alice's Adventures in Wonderland" helped make the sleepy dormouse character a cherished childhood character. But this small, shy, nocturnal mouse is quietly moving closer to extinction -- unless we act now! Even though the IUCN Red List http://www.iucnredlist.org/details/13992/0 classifies the species as Least Concern, the Britain dormouse's population has drastically dropped over "the past hundred years and they are now vulnerable to extinction," reports the West Sussex County Times. http://www.wscountytimes.co.uk/news/your-news/urgent-appeal-to-help-protect-the-dormouse-1-7478265 The IUCN Red List recognizes that even though the mouse is widespread across Europe and Asia Minor, there's a "cause for concern" in parts of
