Technical Comment on Pande et al . (2020): Why invasion analysis is important for understanding coexistence

Abstract

Pande et al . (2020) point out that persistence time can decrease even as invader growth rates (IGRs) increase, which potentially undermines modern coexistence theory. However, because persistence time increases rapidly with system size only when IGR > 0, to understand how any real community persists, we should first identify the mechanisms producing positive IGR.
