QEIB: Modeling Population Dynamics and Trophic Interactions in Systems with Unidirectional Flow

许多种群、社区和生态系统持续存在于某些或所有生命阶段分散在具有强烈方向性偏见的媒体中的环境中。例子包括有风生种子的植物，溪流、河流和河口的水生生物，以及受洋流影响幼虫扩散的海洋生物。本研究的总体目标是开发一个描述此类系统中消费者-资源交互的建模框架。方法是研究一套日益复杂和生态专用性的数学模型。虽然许多结果将有更广泛的应用，但主要的重点是在河流生态学中重要的机制上。

Many populations, communities, and ecosystems persist in environments where some or all life stages disperse in media with a strong directional bias. Examples include plants with windborn seeds, aquatic organisms in streams, rivers and estuaries, and marine organisms with larval dispersal influenced by ocean currents. The overall objective of this research is to develop a modeling framework describing consumer-resource interactions in such systems. The approach is to study a suite of mathematical models of increasing complexity and ecological specificity. Although many of the results will have wider application, the primary emphasis is on mechanisms that are important in stream ecology.
