The foundational concepts behind the persistence of ecological communities have been based on two ecological properties: dynamical stability and feasibility. The former is typically regarded as the capacity of a community to return to an original equilibrium state after a perturbation in species abundances and is usually linked to the strength of interspecific interactions. The latter is the...

A structural approach for understanding multispecies coexistence

Saavedra, Serguei ; Rohr, Rudolf P. ; Bascompte, Jordi ; Godoy, Oscar ; Kraft, Nathan J. B. ; Levine, Jonathan M.

In: Ecological Monographs, 2017, p. -

Although observations of species-rich communities have long served as a primary motivation for research on the coexistence of competitors, the majority of our empirical and theoretical understanding comes from two-species systems. How much of the coexistence observed in species rich communities results from indirect effects among competitors that only emerge in diverse systems remains poorly...
