CONTENT：
European rabbits are in decline in rural areas, yet holding strong in cities. But urban living also comes with a changed lifestyle: instead of being packed into complex burrows, city rabbits seem to live a more solitary life in smaller burrows.
Madlen Ziege from the University of Frankfurt, Germany, and her colleagues studied the burrow structures of several populations of European rabbits from urban, suburban and rural sites in and around Frankfurt.
They found that the closer to the city the burrows were, the smaller, simpler and lesspopulated they became. "I did not expect to find such a clear correlation," says Ziege.

在欧洲乡村地区生活的兔子越来越少了，但是城市里兔子的数量仍然很可观。但是这些生活在都市里的兔子，生活习惯也逐渐改变：这些兔子放弃了那些复杂的兔子洞转而习惯于独自待在更小的兔子洞。
来自德国法兰克福大学的齐格和她的同事们研究了法兰克福附近以及当地都市，市郊以及农村地区的兔子的洞穴，研究发现越靠近都市，兔子洞的规模越小而且越简单，聚集的兔子也越少。齐格说“我没想到会有得到这样的结果。”
