摘要：

Results suggest that foraging decisions involve a balancing of energy gain with the perceived risk of being eaten, that these are evaluated at the scale of individual resource patches, and that Dipodomys merriami accepts proportionately more risk at higher resource levels. This study is one of the first to examine the interaction of responses to predation and patch quality. -from Author
