- Abstract
Food webs are macrodescriptors of community feeding interactions that can be used to map the flow of materials and nutrients in ecosystems. Extracting and interpreting this information in a meaningful manner has been one of the most active areas in ecological research over the last 30 years. One approach is to identify the most important feeding links within an assemblage of consumers, then define a trophic structure that can be compared with other systems. Such comparative food web studies have been used to address theoretical questions regarding trophic connectivity.
