     Now scientists believe that global warming affects hibernating animals, causing them to wake up earlier. While this may seem a little concern, it is in fact a significant environmental problem .The shortened hibernation period could actually lead to significant declines in the populations of several species.

Some of the first concrete evidence of the phenomenon came from Colorado, where researchers at the

Rocky Mountain Biological lab have been observing marmot(旱獭)hibernation behavior since the 1970s.

In the early days of their studies, marmots generally hibernated several weeks into the month of May.

Nowadays, however, temperatures in the area have risen by 2.5 degrees Fahrenheit, and the marmots

are waking up about a month earlier.

     At least the marmots are still hibernating. Several other animals have not been hibernating at all recently. Brown bears in the Spanish Cantabrian Mountains did not hibernate last year. In parts of the United States, chipmunks (花鼠)also skipped the hibernation period. The bears seem to have survived without losing

many individuals. The chipmunks, however, were not so lucky. Many of the animals died of starvation

during the winter.

     The problem with animals waking up early, or skipping hibernation altogether, lies with the creatures'

metabolism (新陈代谢). When an animal hibernates, their metabolism drops significantly. The animals'

heart rate slows, and they require very little energy to live. When the animals awake from their winter

slumber, their metabolism returns to normal.

     But while their metabolism may be as active as it was before hibernation, food sources aren't as

available as they were before. A marmot may wake up when temperatures get warmer, thinking it's spring, but plants will not have gotten the amount of sun they need to signal their spring period of growth. So until

the plants grow, the marmots have no reliable food source.

     Many scientists believe the problem will continue to get worse. In addition to changes in hibernation

patterns, some believe that other animals will also begin to change their migration patterns or begin to give birth earlier. For many biologists, that's a scary prospect. Terry Root, an animal expert at Stanford

University, said: "I do think what we will be facing is the extinction of many species."
