尽管这一技术也曾用在控制和探索鱼、苍蝇以及啮齿类动物的脑中,但这次却是将这项被大肆炒作的技术第一次用于灵长类动物。
2·There is evidence from studies in rodents that cells in a female body do repair damage better than in the body of a male and that surgical removal of the ovaries eliminates this difference.

5·Guinea hogs were expected to forage for their own food, eat rodents and other small animals, grass, roots and nuts, and clean out garden beds.
它们除了喜欢吃一些食物外,还吃一些啮齿类动物和其他小动物,咬嚼草、树根、尖果类的东西,这样同时又像是把花园的地给翻了一遍。
1·Interestingly, the island rule is overturned for small mammals such as rodents, for which gigantism is favored under insular conditions.

4·To sort out this seeming discrepancy, Elizabeth Dumont of the University of Massachusetts Amherst studied the skulls and limb bones of song birds, rodents and bats.
为了找出这种表面上的差异,麻省阿默斯特大学的伊丽莎白·杜蒙特研究了鸟类,啮齿动物和蝙蝠的头骨与肢骨。
5·That public opinion generally welcomes this is, however, a good example of “cutist” prejudice for one species over another: there is no reason to believe that rodents suffer less than other mammals.
(然而,舆论通常会喜欢这种做法,这是“宠物一族”对动物偏好的很好的例证;而且我们没理由相信啮齿动物会经历少的折磨)。
