Food webs are indispensable maps of community organization, but most are crudely drawn - an inconvenient truth that ecologists must confront. A new DNA metabarcoding study quantifies predator-prey interactions and ecological-network structure with long-overdue precision, supplying insight into how large and small carnivores coexist.
食物网是群落组织不可或缺的图谱，但大多数食物网绘制得很粗略——这是生态学家必须面对的一个令人尴尬的事实。一项新的DNA宏条形码研究以早就该有的精确性量化了捕食者与猎物之间的相互作用以及生态网络结构，为大型和小型食肉动物如何共存提供了见解。
