2001年10月至2002年9月在海南大田国家级自然保护区，采用直接观察法和采食痕迹估计法对赤麂的食性进行了研究。

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。

There were no strong correlations between nectary structures and pollinator behavior, although gelatinous or watery nectar was associated with the foraging preference of pollinators.

它们的蜜腺结构和传粉者行为之间没有明显的相关性，但是胶质或水质的花蜜对传粉者的取食方式有一定影响。

The results showed that food ingestion and frequency of the polecat in constant food patches were higher than that in the variable food patches and time of the polecat was the same between two patches during the training period. Only the frequency of the polecat in constant food patches was higher than that in variable food patches when the polecat was starved for 1 day. Its foraging pattern between the two patches was the same as that during the training period when the polecat was starved for 2 days. Meanwhile, the food ingest ion amount in the two patches was not affected by starvation, but the time and frequency of the polecat using the two patches significantly decreased when starvation increased.

研究结果表明，训练期实验中，艾虎对固定食物量斑块中的取食量和利用频次明显高于变化食物量斑块，而对两个斑块的利用时间基本相同；艾虎饥饿一天后对固定食物量斑块中的利用频次明显高于变化食物叠斑块，而对两个斑块的利用时间和取食量基本相同；艾虎饥饿两天后对两个斑块利用程度与训练期的结果相同：同时，艾虎在两个斑块中的取食量均与饥饿程度无关，而对两个斑块的利用时间和利用频次均随饥饿程度明显降低。

Prey selection and foraging behaviour of the steppe polecat Mustela eversmanni were investigated with plateau zokors Myospalax baileyi, plateau pikas Ochotona curzoniae and root voles Mirotus oeconomus offered as preys for paired comparisons in the laboratory.
