...reason for the potential habitat overlap is twofold: grizzlies seem to be expanding their range east and south from the Rockies, mostly as a result of their growing population, says Rockwell. Polar bears, meanwhile, are spending more time on land, as global warming causes ice to break up earlier and refreeze later in the year. And that means that while encounters between these huge bears might be rare today, they could become increasingly common...
Used to be that seeing a man apologize was a little like catching a glimpse of a Bengal tiger in its natural habitat: rare, thrilling, attainable only for truly patient souls. Now it's more like seeing a mountain lion on a busy highway. People wince, wonder how he managed to get himself in this situation and hope it will be over soon...
...Year of the Tiger ends up being anything like every other year over the past few decades, it won't be very good for tigers themselves. The princely animals are among the most endangered species on the planet. In the wild, they number fewer than 3,000; their habitat, which once stretched in Asia from the Pacific Ocean to the Caspian Sea, has shrunk by more than 90% over the past century, and it's shrinking still. "We once had more than 100,000 of these animals," says Sybille Klenzendorf, the director of the World Wildlife Fund's U.S. Species...
Protecting tigers in captivity is one thing, but the bigger challenge is restoring their numbers in the wild. Deforestation and the ballooning human populations in Asia have chased tigers out of their native habitat. Yet the health of the tiger means the health of the planet. "If there is a tiger in the forest, it's a sign that the forest and the other animals in it are healthy," says Varma. "Tigers are the face of biodiversity." Hopefully, then, 2010 will truly be the tiger's year...
...forward-facing horns and a white stripe running down its spine. The prehistoric animal was domesticated about 8,000 years ago, but some aurochs also remained in the wild until the end of the Middle Ages, when scientists believe they became extinct due to overhunting and loss of habitat.
