TY  - JOUR
AB  - How species coexistence (mathematical ‘feasibility’) in food webs emerges from species' trophic interactions remains a longstanding open question. Here we investigate how structure (network topology and bodysize structure) and behaviour (foraging strategy and spatial dimensionality of interactions) interactively affect feasibility in food webs. Metabolicallyconstrained modelling of foodweb dynamics based on wholeorganism consumption revealed that feasibility is promoted in systems dominated by largeeatsmall foraging (consumers eating smaller resources) whenever (1) many top consumers are present, (2) grazing or sitandwait foraging strategies are common, and (3) species engage in twodimensional interactions. Congruently, the first two conditions were associated with dominance of largeeatsmall foraging in 74 wellresolved (primarily aquatic) realworld food webs. Our findings provide a new, mechanistic understanding of how behavioural properties can modulate the effects of structural properties on species coexistence in food webs, and suggest that ‘being feasible’ constrains the spectra of behavioural and structural properties seen in natural food webs.
