Re-introduction of Tigers
The Caspian Tiger once roamed from the shores of Turkey and the Caspian Sea to the mountains of western China. The last of the tigers were killed over 20 years ago, but efforts are now being taken to re-introduce them to their homes in the forests of Kazakhstan. Though Caspian Tigers have their own name genetic tests have shown them to be identical to the Amur Tigers of Eastern Russia. they are not a separate subspecies as previously thought. It will be these Amur Tigers that will be re-homed into the forests of Kazakhstan.
This project was first proposed in 2011 and will continue to take a few years to come to fruition. A National Reserve is being created in order to properly protect the Tigers, while the region must still be prepare with adequate amounts and types of prey for the Tigers. Their diet mainly consists of wild hogs and deer. The government is also working to educate and reassure the general public close to the reserve.

Discussion Questions
1. What are the effects of re-introducing a top predator to an eco-system that has been without for 20+ years?
2. What is the difference between re-introducing a species and introducing a species to an environment. What effects can it have on the introduced species, the predator or prey of that species and the rest of the ecosystem it is being introduced to.

ReplyDeleteRe-introducing a top predator to an eco-system that has been without for 20+ years will affect the food chain not only that but also its hole environment the everything will slowly start dying around it and eventually IT will parish because every species have adapted to survive without being dependent on the tiger because its been gone for over 20 years.
ReplyDelete2. the difference between introducing a species and RE-introducing a species is that when it is introduced it is new never seen before so scientist study it and when it is re-introduced scientist study its ways of adapting and protect it.
1. Re-introducing the Caspian Tiger its ecosystem will affect the food chain as Charles G and their behavior will be affected too. Bringing an animal from a country like Kazakhstan during the lowest -38 degrees in eastern Russia and the -4 degrees in Kazakhstan i don't think the tiger is used to that amount of cold weather.
ReplyDelete2.Re-introducing a species means that the species were there in that region before whilst introducing a species is that the species has never been in that region.It changes the food chain. The predator might even be the prey to the introduced animal.
1. Brining back a top predator that has been gone for 20 years or so is very dangerous to the food chain, and the environment. It will affect the food chain because if you bring a dangerous predator than it will most likely rise to the top of the food chain. It will start killing other animals and will eventually dominate. It affects the environment because of what it does to the food chain, if the tigers kill everything then the forests will become unpopulated which will result in other complications
ReplyDelete1.According to the article,if re-introducing a top predator,the whole food chain and the adaptation of the tigers will be influenced. For example,the prey can be in danger or after years because of the re-introducing the tigers turn into another kind of animal because they need to adapt to the food chain. But if this kind of new spicies can't survive then the tigers are going to be extinct. It is difficult to let most of the prey and predators to get use to the new role they play in the eco-system in order to survive.
ReplyDelete2.Re-introducing a spicies is just to make people get to know about the stuff they don't know about it before and re-introducing a spicies to an environment is to make that species fully adapt to a specific environment and live in.When re-introducing a species to an environment, the food chain can be unbalanced and the prey and predators may get in danger.
1.Re-introducing the Caspian Tiger it is a bad ,dangerous, out of reasons choice for brining back a top predator that has been gone for 20 years into the food chain which rich and colorful.
ReplyDeleteBecause if the people bring the tiger back to the food chain,
tigers will over-hunting the animals for their tasty meal. Also when they start to hunting the lovely animals it will be very easy ,the reason is these animals already have a long time didn't see this species of animals (on the top of the food chain),so they will not be scared about.
If this situation continues it will be no animals on that land anymore . At that time the food chain is going to be unbalance.
2,The same species of animals will be comfortable for the same degrees ,but people put them into two groups ,so one of the groups will feel uncomfortable ,the reason is they will get a sick and feel worse .But the other group of the tigers get the warm weather to life and have good times in their land.
1.the re-introducing the Caspian Tiger is not bad, because 20 year in a pried of evolution is way to short, and 20 years will not have enough time for a huge change in a ecosystem, and i believe if the Caspian Tiger can use to the environment 20 years ago ,it could use to the environment right now. even their will still be some challenges, but i think it will be fine in 50 years. but in this 50 or more years, human might need to give some help to the ecosystem.
ReplyDelete2.it will have change for sure, but if the change is big or small will depend on the species and the ecosystem. if the specie over-hunted in the ecosystem, it will kill the ecosystem. but if the specie is to weak for the ecosystem, it will get killed very soon.
1.Re-introducing the Caspian Tiger into the ecosystem will be a big change for all the other species. The food chain will also change because the wild hogs and deer will have a new predator. That means the deer and hog’s other predators will have less to eat, and there will be less deer and less hogs, we can see the way everything else will change too. Also, all the other animals have learned to live without the tiger. Which means now, the animal’s lives might depend slightly on the tiger after some time. But I believe that the ecosystem will slowly adjust.
ReplyDelete2.Re-introducing a species means that the environment has already seen it. Introducing is putting in a completely NEW species into that environment. Introducing a species into the ecosystem may be dangerous for the animal being introduced and the other animals as well. It would change the food chain as well as the way of life.
1. Re-introducing “The Caspian Tiger” will not be good for the environment because, first of all, the food chain. The specie will end with most of the food and with some species of animals.
ReplyDelete2. Re-introducing a specie: It could be that the specie kill most of the other species or that it would end again. New specie: We don’t know the type of specie that is coming. It could be a predator or a prey. I believe that even if it is a predator or a prey, society has to adapt to it.
1. Re-introducing the Caspian Tiger into the ecosystem will be bad for the food chain because since the Hogs and deers are the main part of the Caspian Tiger's diet the wild Hogs and deer will have a new predator and there would be less and less of them in that area. It is also bad because the Caspian Tiger would have to move from a very hot area to a very cold place and will have to adapt to their new environment.
ReplyDelete2. Re-introducing a species is to make people learn and know about that specific kind. Re-introducing a species to an environment on the other end is to kind of to force them to adapt to a most- likely to be unknown area to them.
1.Re-introducing the Caspian Tiger to a place where they haven't been in 20 years will not harm the ecosystem or the tigers to much. although it will change the amount of food there is for other animal species
ReplyDelete2.for an animal to be re-introduced is very different for an animal to be introduced. because by re-introducing the species, you already know what it can do to the territory that it is in, although if we introduce a new one it could be a threat to the animals around it or even to the ecosystem surrounding it
1. I agree with the opinions of my fellow classmates, I believe that bringing back such a powerful creature into an ecosystem after it hasn’t been there for two decades could be very risky. It could start by diminishing populations of animals in that environment. It could also bring some species to or near extinction! Personally, I do not think this will work as it plans to. I believe it will be bad for the ecosystem around it.
ReplyDelete2. Introducing is bringing something new, while re-introducing is bringing back a matter at hand to a place, ecosystem, or memory etc...
