A female jaguar looks from its cage at a zoo in San Ana, near San Jose, Costa Rica February 2, 2006. Costa Rican zoologists have begun genetic testing on captive jaguars in an effort to increase their numbers. The plan is to use sperm from the captive jaguars and their offspring to impregnate, through artificial insemination, females in the wild areas of Costa Rica, mostly in national parks and protected areas, said Yolanda Matamoros, a zoologist at San Jose's Simon Bolivar Zoo.
