捕食

Hellip;on how polar bear moms subtly initiate their young into the rights of predation through tomfoolery.

Follow-up observation of large volume of transactional data, may be able to discover the whereabouts of their investment predators.

后续的大宗交易数据观察，可以发现其投资的捕食者的下落。

There were no significant differences in soil bacterial and fungal biomass, total nematode density and diversity, herbivore density, bacterivore density and omnivore-predator densities between the trenched and control plots in both mineral and humus soil layers.

切根处理对腐殖质层和矿质土层的细菌和真菌生物量、线虫总密度和多样性、植食性线虫、食细菌线虫和捕食与杂食性线虫的密度均没有显著影响。

A trophic level is ab ecological category that includes organisms with the feeding style.

一个生物营养级是指一个生态种类，这个生态种类包括某一特定的有机体及其捕食的风格。

At each link in this food chain we can recognize three pathways to the next trophic level: decomposition, parasitism andpredation.

在这种食物链的每一个连接，我们能够辨别出通向下一个营养级的三条途径：分解、寄生和捕食。

BIOLOGIST: For example the Tuatara and the night frogs, the flightless crickets and these incredibly bizarre forms, it's a mere sized invertebrate with tast on it which only comes out at night and eats other invertebrates, saucer sized predatory snails, earthworms we meet a lot, things like the Moana kiwi.

生物学家：例如大蜥蜴和夜蛙，不能飞的蟋蟀以及有着不可思议的奇怪外型的动物，它是一种小型的无脊椎动物，只在夜间活动，捕食其他无脊椎动物，茶托状的食肉蜗牛，蚯蚓是常见的动物，还有摩阿纳鹬鸵。

In order to study the uniform persistence and global stability of a delayed nonautonomous three specie predator-prey Lotka-Volterra system without dominating instantaneous negative feedback .

为了研究一类没有即时负反馈控制的3种群捕食者-食饵系统的持续性和全局稳定性；在给定的条件下，利用不等式知识，证明了系统的一致持续性。

Some form of Shooting has been around since prehistoric times, when men hunted prey to secure food or protect themselves from enemies. In the Paris Games in 1900, live pigeons were used as moving targets; this was eventually considered unethical and unsporting, so after 1900 the pigeons were replaced with clay targets (＇clay pigeons＇).

射击运动可能在史前时代原始人捕食或者保护自己的时候就出现了。1900年的巴黎奥运会上，鸽子被用作移动靶子，后被人们意识到是不道德、不符合体育精神的做法，于是出现了黏土做的鸽子靶子。

The results show that in a predator-prey model, when diffusion is absent, the diffusion is the interior impetus of system for its stable equilibrium state transforming to unstable equilibrium state and is the basis for biological mode forming.

研究结果表明：在捕食－食饵模型中，扩散是使无扩散时稳定的平衡态向不稳定的平衡态转变的系统内动力，是生物模式形成的基础。

We find the trivial equilibrium is always unstable, which implies that the system is persistent. It is shown that the system is uniformly persistent when positive equilibrium exists.

此外，我们还证明了当正平衡点存在时系统是一致持续生存的，并利用极限系统理论和杜拉克判剧研究了边界平衡点全局稳定性，这表明此时捕食者种群将绝灭。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
