Tasmanian Devils
Tasmanian devils have been rapidly decreasing in population since the year 1998. The Tasmanian devil only lives in the country Tasmania. Recently scientists have noticed that the devils have been suffering from a deadly disease called devil facial tumor disease. The tumor forms on the animals face or neck and causes them to not be able to eat or drink. The disease was first reported on the animals in 1998 in the north eastern region of Tasmania.
Recent studies show that the devils have been fighting back! A new strain of DNA in
The Australian King Parrot numbers are increasing in suburbs that have a lot of trees. They will eat out of bird feeders in urban
Ring-neck snakes live in various habitats. However, they prefer areas with damp soil and temperatures between 27 and 29 degrees Celsius. Mostly, their habitats are grasslands, rocky hillsides, coniferous forests, farmland, chaparrals, and mixed woodlands. Ring-neck snakes also like hiding, so most of the time they can be found beneath stones or barks from dead trees.
to the muskox (Ovibos moschatus). Around the beginning of September, Arctic vampire lizards will climb up the legs of muskoxen grazing on the last vegetation of the summer. Using its long toes to climb, the Arctic vampire lizard will navigate through the fur of its muskox. Like some snakes, the vampire lizard has a pit organ located beneath the nostrils with which the lizard can detect infrared radiation (Gracheva et al. 2010). The Arctic vampire lizard uses the heat sensing organ to locate where blood vessels lie close to the skin on the muskox. After locating a site, the Arctic vampire lizard will use its razor sharp teeth to first shave the area of hair, then to
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.
scrub brush such as mesquite and creosote, but may also reside in lowland areas of sparse vegetation.¨wikipedia stated most people are concerned when getting bite by the mojave rattlesnake. If this happens to you the bite won't hurt, but if you get bit there will be deadly poison running through your system. This snake is very deadly so I would stay away from it. This deadly snake lives in the southwestern part of the United States, Also in Central Mexico.
It is true that the brown recluse spider walks on eight, they have good vision, also they lived in Nebraska and other southern states, the brown recluse spider has two fangs in their mouth, they eat firebrats, soft bodied insects
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.
Female snakehead fish can spawn 15,000 eggs per spawn, and spawn up to five times every year. This means that the snakehead population is rapidly increasing. Snakeheads eat many native fish, and have a diet similar to a largemouth bass. Their diet coupled with their rapid growth is a recipe for disaster in the United States. Snakeheads can eat entire ecosystems in such a short amount of time, they can take over major lakes and rivers. This is the greatest environmental threat because of how fast they can reproduce.
(Evolution.berkeley.edu, 2008),which causes starvation in 12-18 months due to feeding difficulties and therefore death (Deakin and Belov, 2012) . This fatal disease affects only Tasmanian devils, marsupial carnivores of Tasmania. Scientists reported that devils may be responding to DFTD by breeding earlier before the disease kills them, which could help the species survive longer (Hamede, McCallum and Jones, 2012).
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
I FEEL NAKED. EXPOSED. As if my skin, bone, muscle tissue, cells have all been peeled back, down to a tidy swirl of DNA. It's the basic stuff of life, the billions of nucleotides that keep me breathing, walking, craving, and just being. Eight hours ago, I gave a few cells, swabbed from inside my cheek, to a team of geneticists. They've spent the day extracting DNA and checking it for dozens of hidden diseases. Eventually, I will be tested for hundreds more. They include, as I will discover, a nucleic time bomb ticking
The tazmanian devil are suffering from a disease called devil facial tumor disease or a (DFTD) and people are destroying their home. 1 The time was noticed the disease in 1996 when it spread 80% of the tasmanian devil population. 1 According to Department of Primary Industries DFTD is extremely unusual: it is one of only four known naturally occurring transmissible cancers. 1 It is transmitted like a contagious disease between individuals through biting and other close contact. 1 The disease attack mature adolescents(witch in the t-devilcase 2 years old). 1 According to Department of Primary Industries In diseased areas, nearly all sexually mature Tasmanian devils (older than
The United States of America, a country driven by business, money, and technological advancement, has the third highest corporate income tax rate in the world; the highest among the thirty-four industrialized nations of the Organization for Economic Co-operation and Development (OECD) (Pomerleau, 1). Large corporations that have developed in the United States have recognized this. In 1982, McDermott Inc., with the help of its lawyers, developed a strategy in which they could continue with their business, founded in New Orleans, without having to be punished by the prohibitive tax rates employed by the U.S. government (Mider, 2). Thus, the corporate tax inversion was conceived; an idea that allowed businessmen and women that have used
The Golden Age of Ancient Athens The Golden Age is a famous cartoon representing Ancient Athenian life with humor and facts. The creator, Larry Gonick, was born on July 19, 1946 in San Francisco, California. Gonick studied mathematics at Harvard University and graduated in 1967, followed by a master’s degree in math also at Harvard. The objective of this paper is to inform us about Ancient Athens while being humorous and accurate.
Seven Billion. This number may not be that large when we are applying it to a population of bacteria. But when it comes to people on Earth, the number becomes a little more daunting. In a world full of poverty and environmental destruction, people start to wonder, how many people is too many? This question may seem only newly relevant as we have become more aware of climate change and human effects on the health of our planet, but the truth is this question has been raised for hundreds of years. In fact, in 1789 Thomas Malthus rose awareness of the issues of population growth when he anonymously published his essay. In Thomas Malthus’ An Essay on the Principle of Population, the author discusses why and how a population needs to be checked. Malthus brings up great points for his era but fails to predict one of the main reasons why a population needs to be checked.
