Scientists cheer gorilla find, but warn of threats

In this photo provided by the Wildlife Conservation Society, a western lowland gorilla silverback is seen among members of a group in the Republic of Congo Thursday, July 31, 2008. A new census conducted by WCS and the government of the Republic of Congo tallied more than 125,000 western lowland gorillas in the northern part of the country. Previous estimates from the 1980s placed the entire population of western lowland gorillas, which occur in seven Central African nations, at less than 100,000.
