Establishment is an important stage of biological invasions, which corresponds to the formation of a persistent population in the introduction area. It is not trivial, as introduced populations are often small, and subject to various specific mechanisms, which increase extinction risks. The spatial structure of the introduction area, which is...

One of the major predictors of establishment success for an introduced species is the match between its intrinsic characteristics and the biotic and abiotic conditions of its new environment. Yet, the introduction area is likely a landscape made up of heterogenous habitats. Right after their introduction, individuals might disperse across the...

An important prediction of spatio-temporal population dynamics models is that habitat quality, as determined by the carrying capacity of the environment, should have no in uence on the velocity of population expansion. This is for instance the case with the Fisher-KPP model, where the asymptotic spreading speed of solutions is entirely...
