Abstract EN
Compared to the vast literature linking competitive interactions and speciation, attempts to understand the role of facilitation for evolutionary diversification remain scarce.
Yet, community ecologists now recognize the importance of positive interactions within plant communities.
Here, we examine how facilitation may interfere with the mechanisms of ecological speciation.
We argue that facilitation is likely to (1) maintain gene flow among incipient species by enabling cooccurrence of adapted and maladapted forms in marginal habitats and (2) increase fitness of introgressed forms and limit reinforcement in secondary contact zones.
Alternatively, we present how facilitation may favour colonization of marginal habitats and thus enhance local adaptation and ecological speciation.
Therefore, facilitation may impede or pave the way for ecological speciation.
Using a simple spatially and genetically explicit modelling framework, we illustrate and propose some first testable ideas about how, when, and where facilitation may act as a cohesive force for ecological speciation.
These hypotheses and the modelling framework proposed should stimulate further empirical and theoretical research examining the role of both competitive and positive interactions in the formation of incipient species.
