捕食

We also conclude that the equilibrium of the prey population will be enlarged due to the Allee effect of the predator, but the Allee effects of the prey may decrease the equilibrium value of the predator, or that of both the predator and prey.

如果捕食者受Allee效应的影响，则猎物种群在平衡点的密度将增大；但是猎物的Allee效应将同时减小捕食者和猎物在平衡点的密度，或者减少捕食者在平衡点的密度。

In fact, in reallife, the prey species will be usually a?ected by the patchy environment, oncethe food in their patch is exhausted or there are abundant natural enemies intheir patch, they will leave in search for new habitats or refuges, at the sametime, the predator species also will be confined in a isolated patch, when thereis little food to feed on or the last prey is eaten the predators will depart andbecome predator dispersers.

事实上，在现实环境中食饵种群通常会受到斑块环境的影响，一旦在一个斑块上的食物吃完了或者存在太多天敌，它们会离开这个斑块寻找新的栖息地或避难所，同时捕食者种群同样会受到隔离斑块的影响，当在某个斑块上食饵种群稀少或吃完了最后一个猎物，捕食者种群将会离开变成迁徙者到其他栖息斑块上寻找猎物。

Biomass of M. micrura and C. vicinus increased with increased trophic level of the lake water, while biomass of large-bodied cladocerans (D. galeata and Leptordora kindti) decreased with increased fish predation, and relative abundance of calanoids to cyclopoids tended to decrease with increased fish predation.

微型裸腹溞与近邻剑水蚤的优势度随水体营养水平的上升而上升，而大型枝角类（盔型透明溞与透明薄皮溞）的优势度随水体中鱼类捕食压力的上升而下降，哲水蚤相对于剑水蚤的优势趋向于随鱼类捕食压力的上升而下降。

Ancient Man was not a hunter but the hunted, according to new research that suggests that human intelligence and social co-operation evolved to allow our ancestors to escape predators rather than to catch prey.

古代人类不仅不是捕猎者，反而是其它动物捕食的对象。最新一项研究结果显示，人类的聪明才智及社合作能力之所以不断进化，是为了使自身逃脱捕食动物的追赶，而非猎取它们。

The system adopts C8051F020 single chip microcomputer to realize the communication with the robot principal controller by means of serial port. With a compact structure, the performance of the system is unaffected by the installation position, so it can be assembled to other type of robots as a robot standardized component , in order to help the robot to complete the olfaction-related work.3. Inspired by the foraging strategies of animals, a strategy of odor source localization is put forward based on the animal predatory behavior. The strategy fuses the information of gas sensor, wind direction sensor and ultrasonic sensor etc. and integrates several good search algorithms such as Z-shaped search, upwind search and fuzzy neural network search and so on.

该系统结构紧凑，性能不受安装位置影响，可作为机器人标准化组件组装到各种类型的机器人上，以帮助其完成与嗅觉有关的工作。3、受动物捕食策略的启发，提出了一种基于动物捕食行为的机器人味源定位策略，融合了气体传感器、风向传感器、超声传感器等传感器信息，整合了&Z&形搜索、逆风搜索，模糊神经网络搜索等多种较优的搜索算法。

The seasonal pattern of parasitism of the white-backed planthopper, Sogatella furcifera, was investigated in a subtropical double cropping of rice ecosystem in hilly region Jinghua-Quzhou Basin, Zhejiang, China.

在亚热带浙江金衢盆地的丘陵双季水稻田的早、晚稻期间研究了白背飞虱的被寄生和被捕食作用下的存活率。早、晚稻白背飞虱卵被缨小蜂寄生率分别为 1 1 %和 1 6 %，被捕食及未知因子死亡率分别为 2 3%和 1 6 %。

Anurognathus was a tiny pterosaur that had a short head, pin-like teeth for catching insects, and although it traditionally is ascribed to the long tailed pterosaur group, its tail was comparatively short, allowing it more manoeuvrability for hunting in woodland.

蛙嘴龙是一种体形小巧的翼龙。它的头短短的，牙齿像针一样，利于捕食昆虫。尽管传统上将它归入长尾巴翼龙群，但蛙嘴龙的尾巴相对较短，使其在林丛中捕食更具有灵动性。

Hawks that hunt over meadows and marshes and prey on small terrestrial animals.

陆地动物在草地和沼泽地带捕食的鹰，捕食小的陆地动物。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
