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.

许多人口、社区和生态系统在某些或所有生命阶段分散在具有强烈方向性偏差的媒介中的环境中持续存在。例子包括风生种子的植物，溪流、河流和河口中的水生生物，以及幼虫传播受洋流影响的海洋生物。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。该方法是研究一套日益复杂和生态特异性的数学模型。虽然许多结果将有更广泛的应用，但主要的重点是在溪流生态学中重要的机制。
