Summary:The Sumatran tiger is the most critically endangered tiger subspecies in the world, with fewer than 400 individuals left in the wild. They are only found on the Indonesian island of Sumatra, where they have been relentlessly hunted for the black market and where their habitat is rapidly being lost to agricultural and logging operations.

Rare Tibetan Antelope Listed As Endangered
Link-http://www.sciencedaily.com/releases/2006/03/060330162747.htm
Summary- The Bronx Zoo-based Wildlife Conservation Society (WCS) today applauded a decision today by the U.S. Fish and Wildlife Service to list the Tibetan antelope, also known as "chiru," as an endangered species. Through a series of expeditions to China's windswept Chang Tang Reserve over the past two decades, WCS had played a key role in sounding the alarm about the dramatic decline of this elegant animal due to poaching.
Questions-
Why is this species endangered? from poaching
What could prevent this organism from going extinct? less poaching and laws passed to stop the hunting of this animal
List three things you learned from this article in your own words. if animals go extinct many things could go wrong, fur is worth $15,000 on the black market, laws can be passed to stop the hunting of endabgered species
What impact would the absence of this organism have on its ecosystem/community? less ground would be fertilized and ground would be useless dirt

Batrachochytrium dendrobatidis is causing many toads to be extinct. This is a deadly chtrid fungus. It has already beagan to kill many amphibans around the world, mainly in Australia, South America, and the UK.
Why is this species endangered? Because of a fungal disease.
What could prevent this organism from going extinct? They haven't found a way to control this disease at this moment.
List three things you learned from this article in your own words. I learned that frogs are seen as an important bio-indicator and it acts as an early warning system for environmental problems.
What impact would the absence of this organism have on its ecosystem/community? Climate changes can make the frogs immune systems weak, it can produce air and waterbourne pollutants such as herbicides, habitat loss, and it could make more infections.

Endangered Species: More bear species threatened with extinction
Link:http://environment.newscientist.com/channel/earth/dn12904-more-bear-species-threatened-with-extinction.html
Summary: In the article bears are an important topic in today's time. There are only two bears of a certain species that are still not threatened by extinction. This species is listed as "least concern" by experts. Experts say that if it was not for bears being left out in the wild the population would drop unexpectedly. Some of the species habitats have declined causing the popultaion of bears to do the same.
Questions: Endangered species
Why is this species endangered? The bears are left in the wild and are being hunted
What could prevent this organism from going extinct? Smaller number of hunters
List three things you learned from this article in your own words.
1. Bears are at stake of severe extinction
2.Hunters are the main cause of the extinction
3.The popultaion of the bears is dropping everyday
What impact would the absence of this organism have on its ecosystem/community? Larger population of bears

Heatwave is a hell for threatened bats
http://environment.newscientist.com/article/mg19626323.200-heatwave-is-a-hell-for-threatened-bats.html
Summary: It has been a disaster for flying foxes because at least 3500 fruit bats dropped dead from heat exhaustion as temperatures in Australia's eastern coast rose to almost 43 celsius. Students from the Universitity of Ulm in Gernmany have been analyzing the affects of the temperature and the survival of the bats. The killing of the fruit bats will have a serious knock-on effects in U.S.

Jumping Mouse Considered for Protection
Link: http://ap.google.com/article/ALeqM5hGNmjo4sZaK7c7uuIHFuDW-SMyVAD8TCTJLG0
Summary: This article opens by telling you that the New Mexico meadow jumping mouse is up for consideration to become and endangered species. Other candidates include a snail and a frog from Arizona, a fish from Tennessee and a variety of buckwheat found in Nevada. The list names 280 plants and animals in all.
Why is this species endangered? This species is most likely endangered do to grazing and the loss of habitat. The mouse depends on moist meadows along streams and rivers to make its homes which due to the drought could be a problem.
What could prevent this organism from going extinct? The article does not list how they can prevent extinction but they do say that they can work with land manager once it's on the list.
List three things you learned from this article in your own words. I learned that their are species that have been up for the list for over 25 years, Their are many different organisms up for the list, being a candidate for the list does not grant you the protection.
What impact would the absence of this organism have on its ecosystem/community? The article does not state a direct impact but the mouse is prey for some species.

Giant Panda Can Survive
http://www.sciencedaily.com/releases/2007/08/070824104831.htm
Summary: The article was saying that genetic development is not the cause of Panda decline. Instead scientists believe in fact that humans are the cause. Scientists believe that human activities are the main reason for the decline. The Panda's habitats are being desroyed so they can't reproduce well because they have not adapted to the new habitats.
Questions: Why is this species endangered? The Panda is endangered because of deforestation and poaching.
What could prevent this organism from going extinct? New conservation efforts
List three things you learned from this article in your own words. Humans are hurting the panda populations, more and more panda's are being hunted, and without conservation efforts the Panda's could end up being in some major trouble.
What impact would the absence of this organism have on its ecosystem/community? The bamboo habitats will eventually overrun other habitats and hurt even more of the ecosystem.

Summary: An endangered butterfly called the Sand Mountain blue buuterfly is becoming extinct. it only exists at Sand Mountain in a county called Churchill. It lives on a host plant called a Kearney buckwheat.
Questions: Why is this species endangered? their habitat has been destroyed off-road and the population is declining because of the people around them(humans destroying them).
What could prevent this organism from going extinct? The butterfly could keep from becoming extict by being put in wildlife habitat. Or someplace like a zoo to keep it from becoming extinct.
List three things you learned from this article in your own words. 1. I learned about a new kind of butterfly. 2. I learned why it is becoming extict. 3. I learned about what the butterfly lives on(type of plant).
What impact would the absence of this organism have on its ecosystem/community? The impact that the butterfly would have on the ecosystem or community is the butterfly population would decrease and there wouldn't be anymore.

Giant pandas under threat from parasitic worm, Ukyla Johnson
http://environment.newscientist.com/article/dn13016-giant-pandas-under-threat-from-parasitic-worm.html-
This parasitc worm found in many giant pandas are becoming extinct. Even though they are already close to extintion they are under a lot of pressure of not becoming fully extinct. Tehy had fond that from the 1990's onwards many pandas that were dying was because of parasitic problems and not just natural deaths.
Why is this species endangered? This species is about to become exctinct because of a parasitic worm.
What could prevent this organism from going extinct?If they found a way to kill the worm and stop it from spreading throught the panda population.
List three things you learned from this article in your own words. I learned that the disease from the worm causes haemorrhaging of the liver, intestines, and lungs. I also learned that the name of the disease is visceral larval migrans.I have learned also that the parasit has mabye been brought on because of the deforestation.
What impact would the absence of this organism have on its ecosystem/community? It could cause all the pandas to die away and then animals will probobly start having to live closer together if they keep cutting down trees making the parasite move from host to host.
