Yet only in the last 10 years has the study of animal personality started to gain ground with behavioral ecologists, said Jennifer Verdolin of the National Evolutionary Synthesis Center, in Durham, NC.   She and a colleague have now found distinct personalities in the grey mouse lemur（狐猴）(Microcebus murinus), the tiny, saucer-eyed primate native to the African island of Madagascar.   In a study published in the journal Primates, Verdolin gave fourteen gray mouse lemurs living at the Duke Lemur Center a personality test.   Verdolin filmed the lemurs' reactions to a variety of familiar and unfamiliar objects -- such as a tissue box, an egg carton, an orange ball, and a stuffed toy frog -- which she placed one at a time into the animals' enclosures. She then measured how long it took each animal to work up the nerve to approach and investigate each object. Mouse lemurs that were quick to approach objects were considered "bold," whereas those that behaved more cautiously were considered "shy."   She also noted how agitated（激动的，焦虑的） the lemurs got when handled by their human caretakers during routine weigh-ins and cleanings.   Verdolin found that those that hung back were also harder for their human caretakers to handle, meaning the lemurs' distinct personality traits held up across a range of situations.   The report that mouse lemurs have distinct personalities doesn't come as a shock to staff at the Duke Lemur Center. "[The mouse lemur named] Pesto is very chatty. Asparagus gets beat up by the girls. Wasabi is mean as sin, and her favorite flavor is human fingers," said Duke Lemur Center researcher Sarah Zehr, who was not an author of the study. Other scientists have also found evidence of personality differences among grey mouse lemurs living in the wild.   But for animals living in captivity, Verdolin hopes that personality studies like hers will help researchers determine which individuals are best candidates for breeding programs or for reintroduction back into the wild, as has been done with the North American swift fox, the giant panda, and the golden lion tamarin（绢毛猴）.   The next step, Verdolin says, is to determine the extent to which lemur personalities are influenced by the presence of other individuals, or whether behavioral training for some personality types could improve their chances of surviving in the wild. 谁曾经拥有的宠物会告诉你，它有一个独特的个性。然而，仅在过去的10年已经开始抬头的动物个性的研究与行为生态学家说，珍妮弗Verdolin，在卡罗莱纳州达勒姆国家进化综合中心。   她和他的同事已经在灰色的鼠狐猴（狐猴）（鼱Microcebus），微小的，飞碟眼睛的灵长类动物，原产于非洲马达加斯加岛发现了鲜明的个性。   在“灵长类”杂志发表的一项研究中，Verdolin了14个灰色的鼠狐猴生活在杜克狐猴中心的个性测试。   Verdolin拍摄狐猴的反应，各种熟悉又陌生的对象 - 比如纸巾盒，一个鸡蛋纸箱，一个橙色的球，和一个毛绒玩具青蛙 - 这一次她放在一个进入动物的外壳。然后，她测量了多久每个动物神经接近和调查每个对象。快速接近对象的鼠狐猴被认为是“大胆的”，而那些表现得比较谨慎，被认为是“害羞”。   她还指出，如何激动（激动的，焦虑的）狐猴时得到他们的人类管理员在日常秤上称体重和清洁处理。   Verdolin发现，那些挂回他们的人类管理员更难处理，这意味着整个范围的情况下举行的狐猴鲜明的个性特征。   鼠狐猴有鲜明的个性，不来的，作为杜克狐猴中心的工作人员震惊。杜克狐猴中心研究员莎拉泽汉弗，谁不是一个作者的“鼠狐猴命名为香草是非常健谈。芦笋得到打了女孩。芥末如罪是指，说：”她最喜欢的味道是人的手指，研究。其他科学家也发现灰色鼠狐猴生活在野外的个性差异的证据。   但对于生活在圈养的动物，Verdolin希望像她这样的个性研究将有助于研究人员确定哪些人是育种或放回野外放归的最佳人选，因为已经做了与北美迅速狐狸，大熊猫，金狮狨猴（绢毛猴）。   下一步，Verdolin说，是要确定在何种程度上影响狐猴个性由在场的其他人，或一些人格类型的行为训练是否可以提高他们在野外生存的机会。 “成千上万人疯狂下载。。。。。。 更多价值连城的绝密英语学习资料， 洛基内部秘密英语，技巧，策略 请在 网上 申请报名” 洛基国际英语 竭诚为您服务
