Giant pandas are endangered species, the giant panda worldwide adds up to thousands, most of them still live in the wild.

Another endangered animals in the wild South China Tiger although has been very difficult to find, but also in the Zoo. Inhabit? man last seen at close range that inhabit the famous Qi Qi, died in 2002. Mankind's last distance saw that inhabit in April this year, because of the distance is too far away, and no photos, no one would dare say it beats his chest is a inhabit.

Inhabit a letter by the media "Goddess of the Yangtze River", "may in fact in the mid-1950s was the establishment of a China production bag factory, is a" Goddess "skin.

According to statistics, in 1980, when there are approximately 400 Yangtze River head of the last century that inhabit this figure drops to less than 50 head. There are live now inhabit? nobody knows.

We all know, when a population decline in the number of individuals to a certain extent, their genetic diversity will be damaged, long-term inbreeding will greatly reduce the population of reproductive capacity and resistance.

According to this standard, inhabit as early as the time of the last century have been close to the edge of extinction, must take the "ex situ conservation" means, in other words, it must be possible to put all catches of individuals caught, to facilitate control of the artificial environment to reproduce. However, for various reasons, our scientific community hasn't been able to do so and let that inhabit in the crowded the Yangtze River is illegal fishermen not harming, was killed between vessels, are chemical pollutants poisoned.

At the end of last year, which is the distance from the last census of mass that inhabit that eight years in the past, the experts at the San Diego United States convened a conference after the meeting it was agreed that must immediat

ely begin to implement the "ex situ conservation", this is the last chance that inhabit. But who do not know how much is left of the Yangtze River inhabit, a census of the Yangtze River. However, the investigation requires 100 million RMB, nobody is willing to out the money until the United States Budweiser beer and Switzerland SGS (SGS) out of about half a million, that is to be carried out. 6 November this year, a team of more than 30 foreign scientists of expedition by two research vessels proceeding from Wuhan, began a period of one and a half months of tours along the River.

This study uses a group of trained observers, greatly improves the accuracy of measurement.

Japan also hired a cetacean acoustics expert Dr. Pinus densiflora Woo Sung to join the expedition, he will use the world's most advanced acoustic monitoring device records the Baiji's high-frequency "ticks" sound. Akamatsu Woo Sung is the Japan Institute of aquatic science, acoustic experts he brought two underwater microphones equipment, professional terminology called "hydrophone". However, the official investigation for 5 days later, the friends of Pinus densiflora into nothing.

During the inspection process, honghu reserve funding difficulties also impressed me.

Honghu reserve staff each month's wages only 850 block, often in arrears.

Reserve was allocated per year is $, even afford gasoline, had to rely on the penalty, as well as the sale of confiscated electric fishing equipment to fill the deficit. Another of the Yangtze River inhabit reserve — Swan Island protected areas actually had to open commercial fishing on a regular basis, because the revenue to reserve one-third of the daily activities of the funds.

The entire interview, protected areas and the Chinese Academy of Sciences of the stakeholders are most afraid of the reporters said that inhabit is extinct, because this would be even more inadequate.

In fact, apart from the Yangtze River in mammals that inhabit, finless porpoise. Finless porpoise is the local people called the "River pig", fishermen to catch them, it is said that unlucky, but escaped the porpoise. Even so, finless porpoise day. In 1993, when there are approximately 2700 head, currently estimated to have less than 1000 head. Protection that inhabit all of funding and facilities can be used to protect the finless porpoise. However, if scientists don't draw lessons, finless porpoise in the near future and that inhabit the same extinction.

All the fresh water of the Yangtze River is a river in the world only has two mammalian River, because living mammals eat fish, animals belonging to the top of the food chain, are highly sensitive to environmental change.

Therefore scientists think top animal extinction heralds the collapse of the entire food chain, thus also foreshadowed the collapse of the entire environment. A scientist with specialized fishing Germany plankton nets in the Yangtze River fishing for 10 hours, only two do not catch up to 1 cm long shrimps! according to reserve staff introduction, now illegal fishing in the Yangtze River are very rare, because even they would not get enough fish to earn back the cost.
