捕食

The cuvier's beaked whales dive deep into the ocean in search of food .

居维叶突吻鲸要潜到很深的海底进行捕食，当这些鲸鱼捕食的时候，它们发出的声纳信号遇到物体会反射给鲸鱼，这个过程称作声纳定位。

And that predators are statistically much more likely to dream than prey, which are in turn much more likely to experience dreamless sleep.

从统计上看，食肉动物比被捕食动物有更多的有梦睡眠，而被捕食动物更多地无梦睡眠。

The first chapter discusses the showness of geometric figure and equilibrium\'s asymptotically stable of mathematical model of predator-prey.

第一章利用分析技巧和霍维茨定理研究了捕食与被捕食种群的循环Hassall数学模型几何图形表达和平衡点的渐近稳定性问题。

Those analysis have shown that the nutritional quality of producer can impact the living rate of grazer and even lead to extinction , and grazer-producer interactions can shift from a type to an unusual class.

已研究的成果表明，食饵的营养质量会影响到捕食者的生长率甚至会导致种群灭绝，而食饵-捕食者之间的关系也由传统的型转化为型。

In Hangchow it has four generations each year and the time of its occurrence is well synchronized with that of the scale.

根据测定，隐斑瓢虫对日本松干蚧各虫态的捕食能力较强，一头成虫的日平均捕食量为：显露若虫13.33头，雌成虫4.27头，卵囊3.67个(每个卵囊内平均有卵265.5粒)，雄蛹28.27只；一头幼虫全期(或2—4龄和3—4龄)分别能捕食显露若虫39.20—105.56头，雌成虫40.80—47.79头，卵囊39.38—41.79个，雄蛹220.50只。

I've had the opportunity on lots of occasions to watch Lionfish of various species in the wild, both in dormant daytime mode, Night dusk and dawn hunting mode, and on rare occasions full daylight hunting mode in the case of some larger P.volitans individuals, or groups.

我有幸能在自然海域中观察各种狮子鱼，大多数狮子鱼都是白天休息，黄昏和黎明时捕食，极少有全天捕食的生活模式，一些较大型的P.volitans个体或群体才会这样。

The deduced integral invariant is employed to study the 3D predator-prey Lotka-Volterra systems and some new results are obtained.

利用此积分不变量，对三维捕食被捕食 LVS解的渐近性进行讨论，得到了平衡点全局渐近稳定的新条件，推广了已有LVS正平衡点全局渐近稳定的结

We found 110 Kentish Plover nests in 8 sites, total area 22.74 ha, in Shengshi, Changhua during mid-April to mid-May. The hatching success of 89.09% was high compared to other studies. Thirty-six experimental artificial nests were set for a two weeks period in May to examine the effects of predators and rainfall. Among the 12 unsuccessful nests, 6 were flooded, 4 were abandoned, and 2 were predated. Successful nests and unsuccessful nests showed no difference in distance to nearest road and distance to nearest vegetation line.

调查从四月中旬至五月中旬於样区共追踪110巢东方环颈鴴的孵化情形，并於五月份设置36个人工试验巢进行两星期的追踪以了解捕食和降雨对孵化成功率的影响程度。110巢东方环颈中有98巢成功孵化，孵化成功率高达89.09%，以Mayfield Method 估算之孵化成功率亦高达83.53%，未孵化的12巢中，有6巢是因降雨淹水而失败，4巢是亲鸟弃巢，2巢被捕食。

The time and frequency of the polecat searching different preys and burrows were nearly the same. The polecat attacked virtually all prey offered and thus exhibited opportunistic foraging behaviour. However, it did not captured all prey with equal sequence. It first captured the zokor, then the pika and last for the root vole. In addition to using the typical musteline killing method of biting the nape of the neck, the polecat evolved a variety of killing methods suited to a range of prey types depending on the activity, size and anti-predation ability of prey. The zokor was bitten on the head, whereas the pika was killed by bites to the head or throat and the root vole was killed by bites to the head or chest. The time polecats pursued the root vole was the longest, followed by that used in pursuing the pika and the zokor.

实验结果表明：艾虎对三种猎物的搜寻时间和搜寻频次基本一致，在搜寻猎物的过程中并非已知洞道系统中所存在的食物信息，是一种机会主义的捕食者；艾虎除了具有典型鼬科动物捕杀猎物的方法外，能够根据猎物的大小、活动性和反捕食能力采用不同的捕杀方法，在捕杀猎物的过程中首先捕杀高原鼢鼠，其致死部位全部为头部，其次捕杀高原鼠兔，其致死部位除了头部外，明显增加了颈部的比例，最后捕杀根田鼠，其致死部位主要是头部和胸部；艾虎在捕杀猎物的过程中，追击根田鼠的时间最多，追击鼢鼠的时间最少，而用于捕杀根田鼠的时间最少，用于捕杀鼢鼠的时间最多，艾虎捕杀高原鼠兔后单位时间内获得的能量值最大，其次为捕杀高原鼢鼠，而捕杀根田鼠后单位时间内活动的能量值最小。

In the third chapter, we study the existence, uniqueness, global stability of positive solution and MLEs of parameters of Lotka-Volterra competition system, mutualism system and predator-prey system with random perturbation.

第三章研究了具有随机扰动的Lotka-Volterra型的竞争系统，互惠系统和捕食-被捕食系统正解的的存在性，唯一性，全局渐近稳定性以及参数的极大似然估计。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
