Networks are a powerful way to represent the complexity of large ecological systems. However, most ecological networks, such as food webs, contain only partial lists of species interactions.

The ability of a biotic community to resist or adapt to external pressures is closely related to the level of web complexity, which depends on predictable energy supply 1,2,3,4,5,6,7,8,9,10.

Wildlife biologists used a novel technique to trace the movement of carbon through Arctic and boreal forest food webs and found that climate warming resulted in a shift from plant-based food webs to ...
