Wild Tasmanian Devils

The all of tasmanian animals are becoming endangered from dehabitation.The t-devil are dieing from DFTD.The invasive specie are kill the t-devils by the year.People are endangered tasmanian devil and rat and invasive specie giving them disease and take there food.

On April 25,1857 I Riley J Petersen found a species man has never seen before. I was off the coast of Australia, on an island called Tasmania. At first I thought I had stumbled across a pack of wild dogs, but as I got closer I realized that these are no dog.

Texas Horned Lizards (P. cornutum) are currently listed as a threated species in Texas and Oklahoma. Texas Horned Lizard decline has been documented to start in the 1960’s, and is attributed to many things such as the invasion of red fire ants, habitat loss, urbanization, and the increased use of insecticides (Donaldson, Price, and Morse, 1994). These lizards inhabit arid to semi-arid environments and are known to primarily eat harvester ants. However, other invertebrates have been noted such as spiders, crickets, and beetles (Montanucci, 1989). The Horned Lizards dependence on Harvester ants has already been brought to question when it was shown that habitat influences population distribution and not harvester ant availability (Whiting,

The New Caledonian Crested Gecko is one of the most sought out reptiles in the herptoculture hobby today. This medium-sized gecko has all the qualities of what to expect of a pet lizard. They combine their sheer beauty and low maintenance and docile tempers, making it an all around great pet to own (Rhacodactylus, p. 16). In the herpetological society, the crested gecko’s popularity has grown above hobbyist, into the hands of many first time pet owners, giving a first time experience made easy. According to Fester, (2007) “the rare Crested Gecko thought to be extinct but rediscovered in New Caledonia in 1994” (fester’ at Ireland

Tasmanian Devils (Sarcophilus harrisii) are the largest population of marsupials to be found on earth due to the extinction of the Tasmanian tiger (Thylacine). During the 1940’s the Devil species became protected due to large numbers being killed as a form of pest control. The protection of the Tasmanian devil was important as they are crucial to the ecosystem of Tasmania (live science Tasmanian Devils' Mysterious Cancer May Come in Two Varieties). The protection of the devils was necessary as the population have low genetic variability and a history of genetic bottlenecks making them more susceptible to drastic population declines caused by various abiotic

This idea went against all of my previous research, and left me quite puzzled; how could cancer suddenly be contagious and only affecting this one species? My group and I then proceeded to read about the history of the Tasmanian Devil and how it had at one point become extinct in Australia, and only found in Tasmania, hence its name. Through this migration of a whole species and the extinction of all of the devils in other regions, the devils soon got a low genetic diversity. All of the devil's in the region have similar cells, and are practically all related as they all stem from the same original devil and therefore, their bodies are not able to recognize cancerous cells which in turn creates the large scarring and tumors on their

Coyotes may be encountered throughout the year. Raptors include red-tailed hawks, northern harriers, and American kestrels. During winter they may be joined by prairie falcons and rough-legged hawks. During spring and summer watch for upland sandpipers, common nighthawks, eastern meadowlarks, loggerhead shrikes, and grasshopper sparrows. These hills also harbor the largest population of greater prairie chickens in the world. Other than just grass the Kansas prairie has hundreds, nearly a thousand different species of wildflowers. The flowers are often abundant in the roadside ditches and may sometimes be found growing in the middle of the road! In the fall, the bluestem grasses show their subtle hues of blue and red.

Devil facial tumor disease (DFTD) is an infectious disease that is most commonly found within Tasmania Devils. DFTD is a cancerous disease and is commonly carried through liver cells and is spread by biting through mating fights within the Devil population. This cancerous disease is one of the major reasons in how this species is endangered and facing extinction as there have been no recently discovered cures to stop the spread of DFTD. The following annotated bibliography highlights the problems of DFTD within Tasmanian Devil populations and the scientific communities strive to find a cure.

Tasmanian Devils have been labelled as ‘endangered’ species by the Tasmania’s Threatened Species Protection Act 1995. The population of Tasmanian devils have been decreasing due to number of factors including their stage in the food chain, competition, road accidents and destruction of their habitats. The main factor for their decrease in population is the natural death from Devil Facial Tumour Disease (DFTD) which has rapidly decreased their population. One other factor of the reduce in population is from the introduction of the red fox in Tasmania. Red fox is a competition for the infant devils as they share a similar habitat and are similar in size.

Tasmanian devil (Sarcophilus harrisii) populations on the island of Tasmania have experienced a rapid decline during the past twenty years due to the spread of a cancer called Devil Facial Tumor Disease or DFTD. DFTD is a deadly contagious cancer that is characterized by red oozing lesions or tumors that form on the face and mouth of the Tasmanian devil. The cancer spreads from one devil to another when a DFTD infected devil bites a healthy devil thereby infecting the open wounds with cancer cells. Once contracted the devil dies within six months due to infection or starvation because the tumors in mouth hinder feeding. However, researches lead by biologist Andrew Storfer have discovered that some Tasmanian devil populations have evolved a

Ailuropoda melanoleuca (Giant Panda), Ursus maritimus (Polar Bear), and Ursus americanus (American Black Bear) all have the same life cycle. Once a cub is born, they are extremely small, blind, and consist of a little or no hair. Within a few months, the cub’s eyes are open and they begin to develop their natural hair colour as well as begin to crawl. At four to twenty-four months, the cub is able to run, hunt, and start eating solid food. Once a cub turns two years, they become very independent. At this age, the cub will decide whether they want to stay with or leave their mother. At age four to six, a cub becomes mature and is able to mate. Once two same species of the opposite gender have sexual interactions,

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,

Aboriginal spirituality originally derives from the stories of the dreaming. The dreaming is the knowledge and a sense of belonging that the Aboriginals had of the beginning of life and the relationship to the land and sea (Australian Museum, 2011). The dreaming stories are passed on from one generation to the next orally. These stories teach the following generations how to behave towards the land and other people. The dreaming stories give them a sense of duty to protect the land and appreciate it because the dreamtime stories indicate that the spirits have not died but are still alive in different forms as animals or humans, therefore the ancestor’s power is still felt through the landforms (Clark, 1963),

Australian aboriginals are a group of people who are deemed to be the indigenous occupants of Australia. The Australian High Court appreciated them to share a common as well as biological ancestry as Australia's original occupants (de Plevitz, & Croft, 2003). There has however been a lot of ignorance with reference to this group of people more so from the Australians. This has mostly been due to ignorance of these people with most arguments and opinions based on myths (Morphy, & Morphy, 1984, p.459-478).

A case study conducted on a Southern Hairy-nosed Wombat named Zeus showed that operant conditioning could be applied to animals as well as humans (Perth Zoo, 2017). The objective of the training was to improve Zeus’ behaviour after he escaped his enclosure and went on a rampage around the zoo (Perth Zoo, 2017). Through the use of positive reinforcement, Zeus was taught to remain within the borders of his enclosure and go to specific areas upon request, such as upon a set of scales to monitor his weight (Perth Zoo, 2017). Zookeepers used a clicker to act as a bridge to let Zeus know that he was on the right track in learning the desired behaviour of getting on the scales (Perth Zoo, 2017). In addition to the clicker, a target stick was used
