  abstract = {{S}eed dormancy and size are two important life-history traits that interplay as adaptation to varying environmental settings. {A}s evolution of both traits involves correlated selective pressures, it is of interest to comparatively investigate the evolution of the two traits jointly as well as independently. {W}e explore evolutionary trajectories of seed dormancy and size using adaptive dynamics in scenarios of deterministic or stochastic temperature variations. {E}cological dynamics usually result in unbalanced population structures, and temperature shifts or fluctuations of high magnitude give rise to more balanced ecological structures. {W}hen only seed dormancy evolves, it is counter-selected and temperature shifts hasten this evolution. {E}volution of seed size results in the fixation of a given strategy and evolved seed size decreases when seed dormancy is lowered. {W}hen coevolution is allowed, evolutionary variations are reduced while the speed of evolution becomes faster given temperature shifts. {S}uch coevolution scenarios systematically result in reduced seed dormancy and size and similar unbalanced population structures. {W}e discuss how this may be linked to the system stability. {D}ormancy is counter-selected because population dynamics lead to stable equilibrium, while small seeds are selected as the outcome of size-number trade-offs. {O}ur results suggest that unlike random temperature variation between generations, temperature shifts with high magnitude can considerably alter population structures and accelerate life-history evolution. {T}his study increases our understanding of plant evolution and persistence in the context of climate changes.},
