Tasmanian Devil Disease Research Paper

[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.

The song “Black Snakes” by A Tribe called Red and Prolific the Rappers explains to the world that the citizens need to stand up and protest to protect the water between North Dakota to Patoka, Illinois. Prolific the Rappers tell the audience that enough is enough with the companies trying to make a pipeline to collect oil. Prolific the Rappers stated in his line, “A black snake with some black tanks (ugh), how much money do these companies need to make? They could drive their product, but they want to save a buck. Already extracted billions when is enough’s enough.”. He raps this lyric to send a message about the Dakota Access pipeline is only letting the company get rich from the oil and they do not care about what the effect will happen

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

of feral dogs increased. This was a bad thing. This brought on multiple diseases with one of them

The Diadophis punctatus, or more commonly known as the ring-neck snake, is a harmless nocturnal snake that lives throughout the eastern and central part of North America. In Idaho, ring-neck snakes can be found at the west and south-east part of the state.

What became known as Texas tick fever probably arrived in North America sometime in the seventeenth century carried by cattle brought by Spanish colonists from the West Indies. It was transmitted by the cattle tick which required 200 or more frost free days per year for survival. Therefore, its spatial extent was the southern states. Initially, southerners were not terribly concerned about the disease since cattle was rarely a primary economic investment in the southern United States. Antebellum Texas was an exception since it dominated the national cattle industry. By the 1850s farmers in states such as Missouri were turning back cattle drives from Texas for fear of infecting their herds. In some instances there were violent confrontations, assaulting and even killing some of the cowboys. Eventually northern states intervened to protect their herds, instituting quarantine laws against southern cattle. In 1892 the federal government delineated a quarantine line that followed the northern border of permanent fever infestation. The accompanying regulations stated that cattle could only be moved to northern markets between

Why of course I have never been there but “A number of legends exist: that it is bottomless with powerful currents” Link This might explain why many people tell their kids not to touch the pond waters or even go next to the forest.

Since they are such big predators, their population hasn’t been affected or tampered with. The population has been good until now. Up until about 20 years ago, their population was doing fine, but now the disfiguring disease has ruined their population more than anything. Rats and rodents that

The disease is slowly but surely being worn off itself. The devils have started to adapt to the disease and so natural selection has taken effect. They have started to resist DFTD. But in 2016 they have found another disease called DFT2 in the southeastern part of Tasmania.

Transmissible cancers are rare and only 2 other forms of cancer are known to be transmissible, the canine transmissible venereal tumour (CTVT) and marine bivalve cancer (nature communications). Transmissible cancers act differently to other cancers. This is because transmissible cancers are spread between individuals of a population through direct contact, much like how a disease is spread. Whereas other cancers are caused by a mutation causing uncontrolled cell division resulting in a tumour. DFTD is spread throughout the devils by direct contact, most commonly biting. The cancer is mainly spread during fights for mates, food and land however some are spread during mating itself (pnas). Bites between the devils enable a living cancer cell to be transferred between the individuals therefore colonising another host (UOC). DFTD was found to originate from a female host that carried a mutation in a nerve cell. Once transmitted the cancer cell causes tumours to grow on the face and inside the mouth area of the devil, once they reach a certain size they cause the devil’s to starve to their death due to not being able to eat as a result of the size of the tumour (live science Devilish). DFTD has spread to cover almost all the populations of Tasmania causing the population of Tasmanian devils to drop by 95% since discovering the disease (nature

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.

In the text “The Black Death and its Consequences for the Jewish Community in Tarrega,” the authors note that the discovery of communal burial sites in Tarrega (ca. 2007) now provides archeological evidence for the documentary records of the mass murder of Jews in July, 1348. Long before the discovery of the six communal grave sites, testimonies such as that of Hayyim Galipapa (1310 – 1380) have provided textual records for the mass killing of Jews during the spread of the plague. The authors argue that a consequence of the plague epidemic was the increase attacks on social minorities, Jews in particular stood out as a powerful minority group which many of these attacks focused around. As such, the Jewish community suffered disproportionately

Commencing with, Australia’s species bare little resemblance to creatures around the globe due to the work of adaptation. Notably, the native echidna possesses a body covered with sharp spines (Source 1). The spines work as a defense mechanism against the continents larger carnivores, such as the Tasmanian devil, and are a necessary adaptation in order to preserve the echidna’s population. In a similar vein, the invasive cane toad, brought into Australia to halt the menacing cane beetle from crop

A carnivorous marsupial, the Tasmanian Devil, has been suffering greatly from DFTD (devil facial tumor disease) - but why the population has been so susceptible to DFTD is another question. Tasmanian devils have low genetic diversity, and this factor contributes to why DFTD is so immensely affecting this population. The Tasmanian Devil’s low genetic may have been caused by the widespread killing of the marsupial by bounty hunters, leaving the species with descendants from the same small population. This resulting low genetic diversity from not having a very diverse selection of mates leads to small variation in the genes for their immune systems, which may contribute to the rapid spread of

Many Tasmanian devils’ in the wild are suffering from a killer disease. It is a cancer and is able to spread like a contagious disease.
