大猎物

It is a favourite place for big-game hunters: 8,000 of them hunted there last year, and recreation generates $5m annually for the local economy.

这里是打大猎物的猎人们最喜欢的地方：去年在他们中有8000人在这里狩猎，而且这里的旅游事业为当地经济每年带来500万美元。

Adult snakes are also known to use constriction on larger prey as well.

成年蛇也是已知限制使用较大猎物等。

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。

However, the time of the polecat used to kill prey was reversed for the three prey species. So the polecat depended on its prey handling time and behaviours of prey to select the prey and get the largest net food value.

因此，在室内条件下艾虎对猎物的选择性主要依赖于其本身处理猎物的行为时间分配和猎物的反捕食行为，使单位时间内获得的能量值最大[动物学报 52(3)：437-443，2006]。

The jaguar may suffer from declining prey populations caused by humans because of predator/prey relationships in Neotropical environments and jaguar dependence on Neotropical prey species.

在新热带界环境中，美洲虎由于依赖特定猎物而较大程度地受到人类引起的猎物种群下降之影响，但美洲狮由于可以偏向利用小型猎物或猎物多样化而得到补偿，从而能更好地适应人类的影响。

The teeth of these fleet-footed predators are too small to use as daggers for large kill, but the cats have strong jaws that lock around the throat of prey until the victim stops breathing.

作为世界上奔跑最快的动物，它的牙齿还太小，不足以刺杀大猎物，但是这只猫科动物的利爪足以将猎物的喉勒住，直到猎物窒息。

A hunter chases big game, eg lions, elephants, etc.

hunter指以大猎物为目标的狩猎者。

Evidence from common shore crabs and pied wagtails demonstrates that prey of a size which return the greatest energy reward per unit time are preferred over smaller and larger individuals.

真蟹和白脊令的证据表明捕食者优先选择能使其在单位时间内获得最大能量的一定大小的猎物，而不是比该体积更大或更小的猎物。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
