This project will test the hypothesis that in an African predator-prey system that consists of a terrestrial predator of frog eggs and an aquatic predator of frog larvae. The PI's will test for higher-order interactions in this system through field surveys and artificial pond experiments. Demographic models will then be used to extrapolate the short-term effects of the predators on prey mortaility to understand better their importance in determining prey population dynamics. This research will faciliatea our understanding of the effects of competing HOIs on prey dynamics, quantify the status of amphibian populations in Tanzania, and enhance the ecological training of African and American biology students.

该项目将测试非洲捕食者-被捕食系统的假设，该系统由青蛙卵的陆生捕食者和青蛙幼虫的水生捕食者组成。 PI 将通过现场调查和人工池塘实验来测试该系统中的高阶相互作用。 然后，人口统计模型将用于推断捕食者对猎物死亡率的短期影响，以更好地了解它们在确定猎物种群动态方面的重要性。 这项研究将有助于我们了解竞争性 HOI 对猎物动态的影响，量化坦桑尼亚两栖动物种群的状况，并加强非洲和美国生物学学生的生态培训。
