摘要
A rich body of empirically grounded theory has developed about 食物網s - the 網絡s of feeding relationships among 物種 within habitats. However, detailed food-web data and analyses are lacking for ancient ecosystems, largely because of the low resolution of taxa coupled with uncertain and incomplete 資訊 about feeding interactions. These impediments appear insurmountable for most fossil assemblages; however, a few assemblages with excellent soft-body preservation across 營養級 levels are candidates for food-web data compilation and topological analysis. Here we present plausible, detailed 食物網s for the Chengjiang and Burgess Shale assemblages from the Cambrian Period. Analyses of degree distributions and other structural 網絡 properties, including sensitivity analyses of the effects of uncertainty associ
