General discussion
I- Global changes increase dispersal costs
1) New insights on the impacts of dispersal in a changing world
2) Additive or interactive effect?
3) Impacts of dispersal costs on population dynamics: a matter of timing
4) Expected effects of global changes on dispersal costs
5) Sex-biased dispersal
6) Is dispersal still playing its role?
II – Alternative dispersal tactics: do they suffer the same costs?
1) Why dispersal tactics matter?
2) Two main implications of alternative tactics in a changing world
II- Dispersal evolution with increasing dispersal costs
1) Consequences on population dynamics
2) What about dispersal syndromes?
3) Interplay of numerous ecological factors and selection pressures
