  abstract = {{P}lant germination and development depend upon a seed's successful dispersal into a suitable habitat and its ability to grow and survive within the surrounding biotic and abiotic environment. {T}he seeds of {A}echmea mertensii, a tank-bromeliad species, are dispersed by either {C}amponotus femoratus or {N}eoponera goeldii, two ant species that initiate ant gardens ({AG}s). {T}hese two mutualistic ant species influence the vegetative and reproductive traits of the bromeliad through their divergent ecological preferences (i.e. light and substrate). {W}e hypothesised that the seeds dispersed by these two ant species have underlying genetic differences affecting germination, growth and survival of {A}.mertensii seedlings in different ways. {T}o test this, we used an experimental approach consisting of sowing seeds of {A}.mertensii: (i) taken from the two {AG}-ant associations (i.e. seed origin), (ii) in two contrasting light conditions, and (iii) on three different substrates. {L}ight and substrate had significant effects on germination, survival and on eight key leaf traits reflecting plant performance. {S}eed origin had a significant effect only on germination and on two leaf traits (total dry mass and relative growth rate). {O}verall, this bromeliad performs better (i.e. high growth and survival rates) when growing both in the shade and in the carton nest developed by {C}.femoratus ants. {T}hese results suggest that the plasticity of the tank bromeliad {A}.mertensii is mainly due to environment but also to genetic differences related to seed origin, as some traits are heritable. {T}hus, these two ant species may play contrasting roles in shaping plant evolution and speciation.},
