9723033 Randall Drumming on the ground to create mechanical vibrations is an important means of communication in open, desert environments, and is widespread among desert rodents. Both solitary kangaroo rats, Dipodomys, from North America and social gerbils, Rhombomys, from Central Asia exhibit footdrummming in the presence of predators. Because this behavior costs time and energy and is dangerous, it must provide some benefit. The objective of this study is to determine why desert rodents place themselves at risk by footdrumming in the presence of predators. Behavioral observations and experiments with snake and mammalian predators in the field will test predictions that solitary kangaroo rats footdrum to communicate directly to the predator that the rat is alert and the predator's chances of successful capture are low, while social gerbils footdrum to warn relatives and offspring of danger. Results of the study will contribute to our understanding of footdrumming as a unique form of mammalian communication and its function as anti-predator behavior in ground-dwelling desert rodents. The study should lead to a greater understanding of how predation acts as a selective force on prey behavior and contribute to recovery programs of endangered species of kangaroo rat.

9723033 Randall在地面上鼓声以创造机械振动是在开放，沙漠环境中进行交流的重要手段，并且在沙漠啮齿动物中广泛存在。来自北美和社会沙鼠，菱形，来自中亚的孤独的袋鼠大鼠，Dipodomys，来自中亚的菱形，在捕食者面前展示了足迹。因为这种行为花费时间和精力并且是危险的，所以它必须提供一些好处。这项研究的目的是确定为什么沙漠啮齿动物在捕食者存在下会陷入困境。在野外对蛇和哺乳动物捕食者进行的行为观察和实验将测试预测，即孤立的袋鼠大鼠足迹直接与捕食者交流，即大鼠保持警惕，而捕食者的成功捕获的机会很低，而社交的Gerbils脚下，向危险和危险的危险症状和后台。这项研究的结果将有助于我们理解脚踏板作为一种独特的哺乳动物交流形式及其在地面沙漠啮齿动物中作为抗侵犯行为的功能。这项研究应更深入地了解捕食对猎物行为的选择性力量，并有助于袋鼠大鼠濒危物种的恢复计划。
