2、African wild dogFinding a babysitter while you go out to work is, fｏｒexample, an inconvenience. Fｏｒthe African wild dog, one of the continent\'s most endangered carnivores （食肉动物), it\'s a matter of life ａｎｄ　death. A new research shows that once packs (兽群) fall below a certain size, they are not enough animals to both hunt food ａｎｄ　stay at home protecting the young.The African wild dog has declined drastically over the past century. Habitual loss (栖息地的丧失), persecution ａｎｄ　unexplained outbreaks of disease have all been blamed. Only 3, 000 to5,000 animals remain, ａｎｄ　the species is expected to go extinct within decades if the trend continues.Other large carnivores such as the spotted hyena (鬣狗) face similar pressures, yet are not declining. Now Franck Courchamp of Cambridge University has found a reason why. The dog\'s weakness lies in its social organization.Within each pack of up to 20 adults ａｎｄ　pups, only the dominant male ａｎｄ　female breed. The remaining animals help raise the pups, cooperating to hunt prey ａｎｄ　defend the kill from other carnivores.Because pups can\'t keep up on a hunt, large packs leave an adult behind to protect them from predators (捕猎者), which include lions ａｎｄ　hyenas. But leaving a babysitter also carries costs. A smaller hunting party is less able to tackle large prey ａｎｄ　to defend the kill. There is also one less stomach in which to carry food back to the den, ａｎｄ　one more mouth to feed when they get there.Courchamp investigated this awkward trade-off (权衡) by modeling how the costs of a babysitter change with decreasing pack size. This showed that packs of more than five adults should be able to feed all the pups ａｎｄ　still spare a babysitter. But with smaller packs, either the hunting ｏｒthe babysitting suffers, ｏｒthe animals have to compensate by increasing the number of hunting excursions which itself carries a cost to the pack.Field observations in Zimbabwe supported the model. Packs of five animals ｏｒfewer left pups unguarded more frequently than larger packs did. There was also evidence that when they did leave a babysitter, they were forced to hunt more often.A pack which drops below a critical size becomes caught in a vicious circle (恶性循环), says Courchamp, who is now at Paris-Sud University. "Poｏｒreproduction ａｎｄ　low survival further reduces pack size, culminating in (最终造成) failure of the whole pack. " ａｎｄ　deaths caused by human activity, says Courchamp, may be what reduce pack numbers to below the sustamable threshold. Mammal ecologist Chris Carbone at London\'s Institute of Zoology agrees. Maintaining the integrity of wild dog packs will be vitalin preserving the species, he says.The size of a pack must be big enough fｏｒit to survive.【单选题】
