项目摘要

GOTELLI DEB-9615708 Antlion larvae build and maintain steep-sided pits which are used to trap small arthropods. The probability of the antlion reaching adulthood depends on its ability to locate a suitable site for its pit and to determine when to change sites while avoiding predation. This proposal attempts to unravel the behavioral rules that antlions use in deciding whether or not to stay in a particular pit. The investigators will combine computer models (individual-based simulation models and dynamic programming models) with field data and field and laboratory experiments to evaluate a wide variety of potential behavioral strategies and assess their success under a range of ecological conditions. This work will significantly expand the current understanding of the ecological impact of predators, such as antlions, that sieve prey from the environment. Ant lions are significant predators on local ant communities, and they exert a potentially significant effect on the populations of these economically important organisms. The investigators field experiments will provide data that will enable a quantifying of the potential seasonal impact of antlion predation on local ant populations. This research will provide information on a general class of sit-and-wait predators which are important insect predators.

蚁狮幼虫建造并维持陡峭的坑，用来诱捕小型节肢动物。蚁狮成年的概率取决于它为自己的坑找到合适位置的能力，以及在避免捕食的情况下决定何时改变位置的能力。这个提议试图揭示蚁群在决定是否呆在一个特定的坑里时所使用的行为规则。研究人员将把计算机模型（基于个体的模拟模型和动态规划模型）与现场数据、现场和实验室实验相结合，以评估各种潜在的行为策略，并评估它们在一系列生态条件下的成功程度。这项工作将大大扩展目前对捕食者的生态影响的理解，例如从环境中筛选猎物的antlion。蚂蚁狮子是当地蚂蚁群落的重要捕食者，它们对这些具有重要经济意义的生物的种群数量产生潜在的重大影响。研究人员的实地实验将提供数据，以便量化蚂蚁捕食对当地蚂蚁种群的潜在季节性影响。本研究将为一类重要的昆虫捕食者提供信息。
