Devil Facial Tumor Disease

[Thesis and preview]: Today I am going to share with you a quick history lesson, talk about where these animals currently roam, and explain several threats that this growing population currently faces.

recently become detrimental to many wildlife species. These house cats are responsible for the deaths of

It is also important to remember that there are other factors, such as weather conditions and disease, which can greatly impact the inhabitants of the island. For instance, in the early 1980s an outbreak of canine parvovirus was unintentionally introduced to the wolf population and the wolves were drastically reduced from 50 to 14 in two years. Following this outbreak, the moose population soared to 2400, but in 1996 an extremely severe winter combined with an outbreak of moose ticks decimated the moose population from 2400 to

Rat infestations have swarmed throughout the world, looking for food, and spreading diseases, so of course people attempt to get rid of them. First off, they spread disease. It states in Source 1, “Around 60% of the rodents carry Weil's disease...” This quote states that the majority of all rodents, have Weil’s disease. That means that if you see a rat, it is probably infected with disease. This is incredibly dangerous for people walking the street, or someone without a home. That person who does not have a home, could get a disease very easily. The rats can carry disease and they can spread that disease, it even states in Source 4, “It was this rat which ushered in the Black Plague.” In this piece, they are speaking of Black Rats. These rats were probably one of the unlucky 60%, or it was a carrier something that was on them.

Thylacoleo carnifex or 'Marsupial Lion', weighing at around 120 kg, was the largest mammalian predator in Australia. The megafauna was found Thylacoleo was capable of grasping or slashing its prey with the long sharp claws on its semi-opposable thumb, then stabbing with its large incisor teeth. These animals were common across most of Australia during the Pleistocene period. They became extinct about 50,000 years ago.

They also are very rare to see. As I said, they are only found in southwestern Florida areas. To see these animals would be a very rare occurrence. These species go through a lot, and have trouble being able to stay alive. One of the main problems is humans when it comes to the approach of extinction of certain animals. That is the case in this situation as well. We are the third highest reason for Florida panther’s declines. Florida panthers don’t have sufficient space in some habitats in the Florida area and end up going on the road to get hit by cars. It’s very tragic but true. Other reasons that affect these animals is also habitat loss. When construction is going on it is a huge problem for territorial panthers. This also is another lead to panthers not having a sufficient habitat. Mercury is a big problem for these species when it comes to pollution. These animals are also inept to get a disease called feline leukemia. These innocent creatures go through this on a daily basis. The fact is we have to find a way to keep these species away from harm. Wild lands are converted for cattle grazing, crop, sugar, and citrus production. This wipes out a large portion of these species. Financial weights is more conflicting to alternately poor requirement from claiming existing administrative safeguards. This pushes the destruction as opposed to protection for Florida panther inhabitants in southwest Florida.

The rodent problem has grown in New York City vastly in the last decade; according to Jonathan Auerbach a Columbia doctoral student in his statistical analysis on 2014 called “Does New York City Really Have as Many Rats as People”; there are approximately 2.02 million rodents in New York City and according to the Planning Department, New York’s population raised as 8,405,837 in 2013. If these reports are accurate, there is one rat for four humans in New York City. So, the problem is why New York City has so many rats and how can it decrease/eliminate the population.

These poor creatures are suffering because of us they are starving to death by us losing their habitat by us US US US!!! they are located in the forested mountains and canyons the reasons they don't have food is because we are hunting their food down and killing them this is cruel in Mexico were there supposed to live are extremely low because of US.

They have traditionally been viewed as competitors with cattle for rangeland resources, so eradication programs have reduced populations to less than two percent of those several decades ago (Whicker and Detling 1988). The Colorado Parks and Wildlife have now deemed this keystone species as a species of concern due to sylvatic plague, direct loss of habitat to urban/suburban development, habitat fragmentation, conversion of habitat to agricultural uses, systematic poisoning, recreational shooting, and inadequate regulatory mechanisms. Our biggest concerns are focused on habitat loss and fragmentation and systematic poisoning and how they connect to Colorado’s growth in population.

There used to be more species of sloths, but they’ve become extinct either through natural causes or mankind destroying their environment.

     The rats did it! Rats, almost single handedly, killed off about a third of the

The reading suggests that two possible causes: the environmental pollution and predators attacks. However, the lecture defends that is more probabily is the predators attacks.

Devils are ferocious beasts and that is just what the Tasmanian devil is. The Tasmanian Devil is Australia's top predator and its icon animal. These creatures have developed a disease over the past 20 years called Devil Facial Tumor Disease. This causes large lumps of cancer on the face and neck. This is transferred from one to another with contacts such as a bite and once it has gone into the devils system they can die within 6 to 12 months.

ast week, my group and I were given various pieces of information about the Tasmanian Devil. We had the task of finding out exactly what had caused the scarring and marks on their faces; and could only use the information that was provided to us in folders.

Tasmanian Devils are small marsupials that possess rat like features such as sharp teeth, black or brown fur and are roughly 20 to 31 inches tall. These creatures possess poor temperament, growling, baring teeth and lunging when provoked or under threat. Because of their aggressive behavior, they are solitary creatures, only interacting with one another during the mating seasons of March. They give birth to up to 20 young during this time, however the female as only four teats, meaning only four of the imps can survive. The general lifespan of a Tasmanian devil is 5-6 years, and within that time the devils feed on birds, snakes, fish and carrion (quite often road kill on roads). They live in small dens or old wombat burrows and are nocturnal,
