摘要
Comparative research on 食物網 structure has revealed generalities in 營養級 organization, produced simple models, and allowed assessment of robustness to 物種 loss. These studies have mostly focused on free-living 物種. Recent research has suggested that inclusion of parasites alters structure. We assess whether such changes in 網絡 structure result from unique roles and traits of parasites or from changes to 多樣性 and complexity. We analyzed seven highly resolved 食物網s that include metazoan parasite data. Our analyses show that adding parasites usually increases link density and connectance (simple measures of complexity), particularly when including concomitant links (links from 捕食者s to parasites of their 獵物). However, we clarify prior claims that parasites "dominate" 食物網 links. Although parasites can
