Thylacines Research Paper

In 1993, Steven Spielburg’s Jurassic Park introduced the concept of bringing extinct species back. In 2003, a team of Spanish and French scientists took Spielburg’s movie to the next level—they successfully brought back the Pyrenean ibex, a species of wild goat (93). With increasing rates of extinction, the scientific community is debating whether or not this process of de-extinction should continue to be pursued. Although it would be remarkable to visit an exhibit featuring a saber-tooth tiger or woolly mammoth, these animals went extinct for a reason; humans should not bring back extinct animals, but instead use the funding for more practical purposes.

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.

Conservation of our biodiversity not only demonstrates foresight, it protects the natural resources so vital to our own continued existence. The value of any single species to an ecosystem is immeasurable; the environment will not endure without its species, despite size or niche. These animals are not dispensable. And, they are apt to face extinction in the not too distant future, unless a resolve for their preservation is insisted by the public and enforced by governments internationally.

Megafauna simply means large animals, in which most have become extinct within the last 20 000 to 50 000 years. The extinction of megafauna was, debatably, due to climate change and human expansion. Although, Africa still retains some megafauna, such as the elephant or the rhinoceros. Australia has managed to keep many examples of relict species, some from the time of the megafauna. These include the Crocodile, Wollemi Pine and Stromatolites.

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.

Tasmanian devils have been at the top of the Australian predators. They are one of the deadliest animals in Australia. They are the size full a full grown furry cat. They are full black and have a white stripe in front of their chest. They mainly feast on meat, they are carnivores. They eat snakes and little animals. From eating the tiny rodents and animals, one major downfall has come into play, the Devil Facial Tumor Disease.

"The blitzkrieg model explains the lack of kill sites by reasoning that the extinction of these animals occurred too rapidly to have left much, if any, evidence. Therefore, the uniqueness of Homo sapiens in the New World and Australia, coupled with the lack of kill sites in the archaeological record, can be taken as evidence of blitzkrieg human overkill causing the late Pleistocene extinctions." (Gibbons Robin)

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

The orgimsms involved in Escherichia coli 0157 is an anaerobic bacterium which is shaped like a rod and is Gram-negative. Escherichia is a foodborne pathogen which causes a variety of disease in humans worldwide. Cattle are the reservoir to the diseases. Between 1% and 50% of healthy cattle carry or shed E.coli by means of their faeces. The cattle can also contract the infection after slaughter as conmtanation can occur during slaughter or while the beef is being proceed into products suitable for human consumption. In the United states the most common way of transmission of the disease is through consuming contaminated food and water. Although it is also frequently spread from person to person impartial in communities where there is a high concentration of children such as child care services and primary schools.

The animal I researched is the Geocapromys Thoracatus. Also known as Little Swan Island Hutia. They lived on the Swan Islands of North-Eastern Carribeans in Honduras where their distant cousin the Geocapromys Browni (Jamaican Hutia) also lived. The Carribeans is a very beautiful place, it has clear water and a bunch of trees. The Swan Island Hutia doesn't really have a niche because they emerge from caves and forage on bark,small twigs, and leaves. (www.IUCNredlist.org) (www.flinders.edu.au)

The western grey kangaroo, Macropus fuliginosus, who is also referred to as a black-faced kangaroo, belongs to the macropod family. This particular species of kangaroo is one of the largest macropods in Australia. They are a commonly found across almost the entire southern part of Australia. This species thrives in open woodland and forest, grassland, and can even be found throughout the outskirts of major cities.

Over 128 Animal species are strongly believed to be extinct since European settlement in Australia. In an act to prevent marine pollution by controlling dumping of wastes and other matter, the Environment Protection Sea Dumping Act 1981 was introduced. The legislation outlines the policies and procedures to gain access to Australian waterways (Australian Government Department of Environment, 2015). The current legislation are not able to fully protect the natural environment, as the legislation only implies that permits are required for all sea dumping operations and for those court weak consequences are applied. For those reason, the Sea Dumping Act has been criticised for its ineffectiveness to control the waterways. This essay

The main predators of spectral tarsiers include monitor lizards (Varanus indicus), snakes (Python reticulatus), Malaysian civets (Viverra tangalunga), and various birds of prey, including falcons (Falco sp.) (Gursky, 1997).

Earth is a massive place, and things have a tendency to get lost here. Sometimes it’s just your keys that you swear were on the kitchen table, and sometimes it’s entire species of animals that were thought to be extinct. A hunter in Australia is claiming to have evidence, and the wherewithal the proof that the Thylacine (Also known as the Tasmanian tiger) thought to be extinct is actually still alive. It wouldn’t be the first time that a species was thought to be completely extinct, only to resurface years later.

Thyroxine (T4) is produced by the thyroid gland in the throat. Because of its many
