捕食

Now protected, it is reclaiming lost territory and thriving on voles, mice, and other small mammals.

现在它们都得到了应有的保护，正的找回失去的领地，并随着捕食大量野鼠、田鼠及其它小型哺乳动物而数量增多起来。

Animals such as spiders and snakes use venoms to catch prey and often for defense.

蜘蛛和蛇一类的动物用毒液来捕食，也常用毒液来进行防御。

Most mammals rely on speed to escape being eaten, so even solitary herbivores would be badly advised to grow udders until the proper time.

大多数哺乳动物依靠速度来逃脱被捕食的命运，所以甚至独居的食草动物最好也是在合适的时候再发育乳房。

Humans have fairly high male parental investment, however, and so the males are more valuable, and as said before, mortality due to predation in adult females, even those hampered by udders, would be so low, that this rule could in humans be sex-reversed.

然而，人类中男性比较多地投入到抚养后代中，因此男人更加有价值。正如之前所说，即使被乳房阻碍，成年女性由于被捕食造成的死亡数目仍然如此之低，以至于上述这条法则在人类中性别是反过来的。

Next, a predator-prey system with refuge, toxicants and harvesting is proposed and studied.

第二部分研究一类有避难所、毒素作用、外界捕获影响的捕食-食饵系统。

We saw many threesomes, the romantic triangles of the blue whale, and we witnessed much boisterous courtship behavior, all suggesting that the dome is a mating ground.

借助声纳浮标和声音标签，我们监听到了蓝鲸发出的A声与B声，以及它们在往来捕食的间歇发出的D声。

The result indicate the optimized clutch size is 11 in the nest box by analyzing the reproductive parameter such as hatching period, hatching rate, feeding period, fledged rate, fledgling mass and number fledged of 10 and 11 clutch size.

在育雏前期，亲鸟喂雏频次与窝雏数有一定的正相关关系，而在育雏的中期和后期没有这种关系，说明在育雏的中期和后期亲鸟会最大限度的提高它们的繁殖投入，以保证幼鸟的最佳数量和质量，同时尽量缩短育雏时间，降低被捕食的风险。

We studied escape tactics and effects of risk factors on flight initiation distance in Kalahari tree skinks Trachylepis sparsa and black girdled lizards Cordylus niger by simulating approaching predators.

作者通过模拟捕食者逼近研究喀拉哈里树石龙子和黑环蜥逃避策略和风险因子对逃跑启始距离的影响。

Are controlled in some West Coast waters because of preda-淡水 sculpins

是控制在一些西海岸水域因为捕食

They hunt in groups of two or more and use the tall grasses of Maridun's savannahs as cover.

它们成双或成群地捕食，并利用马里登稀树草原上高大的草木作掩护。
