The architecture of predator-prey and the relationship between complexity and stability [PDF]

open access: yes, 2010
Theoretical studies predict that the stability of an ecosystem is negatively correlated with its complexity, measured by the number of interacting species. On the other hand, empirical evidence indicates that food webs are highly interconnected.
