Fugitive species persist in the face of superior competitors
thanks to a combination of trade-offs (superior colonization
or survival ability) and of stochasticity. Models of the
competitioncolonizationmortality trade-off include sev-
eral forms of stochasticity, and Calcagno et al. (2006)
(hereafter CMJD) introduce yet another, that due to pre-
