Transcript of Tasmanian Devil Project

The Tasmanian devil is found in the Australian Island State of Tasmania
only lives in the grey part
They shelter in caves, bushes, old wombat burrows or hollow logs

And they mostly live in groups of 2 to 5
They reproduce sexually, mostly around March-May, and they give birth to around 25 devils
Tasmanian devils can eat an animal up to the size of a small kangaroo, but mostly they don't hunt but eat dead animal flesh (carrion) and birds, fish, fruit, vegetable matter, insects, tadpoles, frogs and reptiles.

Some biotic factors:
- animals (they eat them)
- frogs (they eat them)
- bones (from other animals an even humans)
- devil facial tumor disease (leads to death by starvation
- plants (for oxygen)
Predators and Prey
- rainfall (for water what keeps them
hydrated
- temperature (not too warm or too cold
so they can easily live there
- sunshine (to keep warm)
- air (to breath)
- landscape (most things they need
are nearby
Some abiotic factors:
The Tasmanian Devil is endangered, so it is not extict, but it is threatened
The Tasmanian Devil population is declined 60% in the last 10 years and Devil Facial Tumour Diseasis most responsible for this declie. Tasmanian Devils became extinct on the Australian mainland about 400 years ago and are now found only on the Australian islans state of Tasmania.
"We have lost over half our Devils in teh past 10 years, with an estimated population of 20,000 to 50,000 mature devils left. Extinction within the next 20 years is a real possibility unless we find a vaccine, eradicate the disease and establish captive colonies." - an Australian Zoologist
Conclusion
On current information, we therefore project atleast 90% population decline over the next 10 years across the 60% of the devil's distribution currently occupied by disease, with at least a 100 km extension of the disease distribution.

Hunting
Why is it the best?
Important Information
More prey
Fewer devils
More devils
Fewer prey
They survive, because there are fewer predators to catch.
More devils can survie, because there is enough prey to be eatan.
All the prey is getting eaten by the devils, there will be fewer prey.
The devils have nothing to eat cause almost all the prey is gone. The devils will starve.
