Individual-Scale Coexistence Mechanisms in Exploitation Competition Systems

9873650 wilson本研究将为生态学领域的实证和理论研究领域做出重要贡献。这项工作也代表了基于个体的生态系统模拟的重要发展和扩展，这是一种日益流行的理论方法。这项研究将建立在过去的建模工作的基础上，该工作使用了一个简单的分析资源消费者模型，该模型检查了两个消费者物种争夺共同的结构资源。这一建议的目标是揭示导致剥削竞争者进化稳定共存的个体尺度的相互作用和过程。它将根据共存期望制定标准并做出预测，对经验系统进行分类和比较。或者换句话说，是否存在一个决定共存的至关重要的特征，有或没有这个特征的经验系统是否符合最终的共存预测？这项研究代表了生态系统模拟的一个重要延伸，其中模拟模型与一系列分析模型结合使用，以最大限度地提高理论洞察力。

9873650WilsonThis research will provide important contributions to both empirical and theoretical research areas in the field of ecology. This work also represents an important development and extension of individual-based simulations of ecological systems, which is an increasingly popular theoretical approach. The research will build upon past modeling work that used a simple analytic resource-consumer model that examined two consumer species competing for a common structure resource. The goal of this proposal is to uncover the individual-scale interactions and processes that lead to evolutionarily stable coexistence of exploitation competitors. It will develop criteria and make predictions to classify and compare empirical systems according to coexistence expectations. Or in other words, is there a critically important feature that determines coexistence and do empirical systems with and without this feature conform to the resultant coexistence predictions? This research represents an important and extension of simulations of ecological systems in which simulation models are used in conjunction with a range of analytic models to maximize theoretical insight.
