Many of us stayed at home in January because of COVID-19, but a special mom and her two babies took a trip. They were 1 a few miles from a breeding (繁殖) center in northeastern Argentina to a 1.7 million-acre nature reserve called Gran Ibera Park. There the three jaguars were released into the 2 . Their release was the first reintroduction of jaguars (美洲虎) in that part of Argentina since the species (物种) almost 3 there 70 years ago. Scientists hope they can turn things 4 for this important species that is on top of the food chain (链). Only 200 to 300 jaguars 5 in the country.
“That is the highest level of protection that can be given in Argentina,” says Sebastian Di Martino. He’s the conservation director for Rewilding Argentina, 6 is one of the organizations helping to increase jaguar populations.
The jaguars’ journey started in 2018 when the park 7 in the Ibera Wetlands. Several thousand jaguars once lived there, along with other important species. But the jaguars’ fur was 8 , so people hunted them. Then farmers cleared the land they lived on. With the jaguars gone, the ecosystem was out of balance (平衡). “In the 9 of this species, ecosystems stop working well and 10 even break down,” Di Martino says. “The main prey (猎物) of the jaguar is the capybara and the caiman. There are plenty of them 11 jaguars have nearly disappeared in this area, which causes imbalances in the ecosystem.”
The park was the first step to give jaguars a place to live. Then they needed to breed. A female named Mariua mated with a male jaguar from Brazil. Mariua then gave birth to the two baby jaguars. It sounds simple, but the reality is more complicated. Di Martino said that jaguars born at breeding centers must not become 12 to humans and have to learn how to hunt by themselves. 13 , they will not have success in the wild.
The people who work at the breeding center stay out of 14 . They use video cameras to watch the jaguars from several miles away. “We provide live prey 15 them, without them realizing it comes from people,” Di Martino said.

Many of us stayed at home in January because of COVID-19, but a special mom and her two babies took a trip.

Scientists hope they can turn things 4 for this important species that is on top of the food chain (链). Only 200 to 300 jaguars 5 in the country.

There are plenty of them 11 jaguars have nearly disappeared in this area, which causes imbalances in the ecosystem.”
The park was the first step to give jaguars a place to live. Then they needed to breed. A female named Mariua mated with a male jaguar from Brazil. Mariua then gave birth to the two baby jaguars. It sounds simple, but the reality is more complicated. Di Martino said that jaguars born at breeding centers must not become 12 to humans and have to learn how to hunt by themselves. 13 , they will not have success in the wild.
The people who work at the breeding center stay out of 14 . They use video cameras to watch the jaguars from several miles away. “We provide live prey 15 them, without them realizing it comes from people,” Di Martino said.
