Elephants , giraffes and large primates ( such as humans ) require relatively little sleep ; rats , cats , voles and other small animals spend most of their time sleeping 大象、长颈鹿以及大型灵长类（像是人类）需要比较少的睡眠；而大鼠、猫、田鼠及其他小型动物，会花比较多的时间睡觉。
The insects that colonize carcasses are devoured in turn by wasps , birds and other insectivores , including small mammals such as voles and mice , that eat not only the insects but the carcasses themselves ?据鲑鱼尸体的昆虫，会依序被蜂、鸟类和其他食虫动物吃下肚，包括田鼠、老鼠这些小型哺乳类， ?们除了吃这些昆虫，也会直接啃食鲑鱼。
Researchers at florida state university examined the nature of love by studying the brains and behaviour of male prairie voles , picked for their habit of lifelong monogamy and aggression towards other females once they have found a mate 据卫报12月6日报道，美国佛罗里达州大学的研究人员通过研究雄性田鼠的大脑和行为来探索人类爱情的本质。
A central evolutionary trend of the microtine is the gradual development of rootless , very high - crowned cheek teeth that grow throughout life and are well adapted to a highly abrasive diet most fossil specimens are cheek teeth of voles Eva 。田鼠亚科的归属，目前有两种观点。一种是将它作为仓鼠科下的一个亚科，另一种是将它作为鼠科下的一个亚科。
( 3 ) there was only ldh5 in the livers of al l groups of microtus fortis . the ldh4 and ldh5 were absent in the kidneys of the small voles from heilongjiang , but five kinds of ldh isozymes were all found in the kidneys of the other three groups ( 3 )四类东方田鼠的肝脏中都只含ldh5 ；肾脏中，除黑龙江小体型东方田鼠缺乏ldh4和ldh5外，其余三类东方田鼠都含五种ldh同工酶。
In fact , one of cine s most emotional songs " vole , " from the d eux album , later translated into english as the song " fly , " which appears on the falling into you album is a touching memorial to her niece , karine , who was taken from her by this disease 在她12岁的时候， celine制作了她的第一张示范专辑ce n etait qu un reve it was only a dream ，同时她的才华得到了魁北克名经纪人rene的支持。
All groups of microtus fortis showed polymorphism at most of the ten loci investigated . the electrophoretic mobilities of the small voles from heilongjiang revealed great divergence with the other three groups : the small voles from heilongjiang had their particular alleles at six loci ( es - 1 , hbb , gpi , akp - 1 , trf - 1 , ce - 2 ) and the phenotypes of them were completely different at three ( es - 1 , hbb , gpi - 1 ) of these loci . the genetic distances among the voles from hunan , ningxia and the big voles from heilongjiang were ranged from 0 . 0633 to 0 . 2107 while that between the small voles from heilongjiang and the other three groups were ranged from 0 . 7068 to 0 . 8953 结果表明：四类东方田鼠在所观察的10个生化位点上，大部分都存在着多态性现象；黑龙江小体型东方田鼠与其它三类东方田鼠的电泳结果差异较大，在es - 1 、 hbb 、 gpi - 1 、 akp - 1 、 trf 、 ce - 2六个位点土都存在其所特有的等位基因，其中es - 1 、 hbb和gpi - 1三位点上它的基因型与其它三类鼠完全不同；湖南、宁夏和黑龙江大体型东方田鼠三者间的遗传距离在0 . 0633 0 . 2107之间，而黑龙江小体型东方田鼠与其它三类鼠的遗传距离在0 . 7068 0 . 8953之间。
We constructed fences using 2 x 2 x 2 factorial design to examine the effect patterns of food availability , predation and interspecific competition on population dynamics and spatial behavior of reed voles , microtusfortis . we expected to test two hypothesises : ( 1 ) availability of high quality food , predation and interspecific competition have independent and addictive effects on population system dynamics for small mammalia herbivore ; ( 2 ) availabiliry of high quality food could reduce home range and aggressive behavior level between individuals of microtine , predation and interspecific competition have independent effects on spatial behavior of microtine 以2 2 2析因实验设计，在野外围栏条件下，探讨食物可利用性、捕食及种间竞争对沼泽田鼠( microtusfortis )种群动态及空间行为的作用，旨在检验下述特定假设： ( 1 )高质量的食物可利用性、捕食及种间竞争对植食性小哺乳动物种群系统动态具有独立的和累加的效应； ( 2 )高质量的食物可利用性可降低田鼠个体间的攻击行为水平，并导致其巢区减小；捕食与种间竞争对田鼠的空间行为亦有独立的作用。
( 2 ) the liver mdh isozymes of microtus fortis were rather conservation in evolution . the mdhm zones of all voles were located to the same migratory line with the similar activity . the migratory rates of the mdhs zones from all voles were identical but the activity of mdhs of the voles from ningxia was weaker than that of the other voles ( 2 )四类东方田鼠的肝mdh同工酶变异不大， mdhm都在同一泳动线上且酶活性相似，而mdhs虽然泳动速度都一致但宁夏鼠的酶活性较其它三类鼠弱。
? there were extremely significant difference on average home range of male and female voles in different treatment populations ( t = 6 . 251 , p o . 001 ) , and the population mnka were extremely significant correlation with the home range of male voles ( r = - 0 . 724 , p = 0 . 000 ) and female voles ( r = - 0 . 814 , p = 0 . 000 ) Si4 ， p 0刀00人以体重及种群最小存活数为协变量的ancova表明，种群最小存活数对巢区具有极显著的独立作用（ f二18 331 ， p一0刀00人而体重的作用则不显著（ f 1 876 。
