abstract = {Spatiotemporal variability of the environment is bound
to affect the evolution of dispersal, and yet model
predictions strongly differ on this particular effect.
Recent studies on the evolution of local adaptation
have shown that the life cycle chosen to model the
selective effects of spatiotemporal variability of the
environment is a critical factor determining
evolutionary outcomes. Here, we investigate the effect
of the order of events in the life cycle on the
evolution of unconditional dispersal in a spatially
heterogeneous, temporally varying landscape. Our
results show that the occurrence of intermediate
singular strategies and disruptive selection are
conditioned by the temporal autocorrelation of the
environment and by the life cycle. Life cycles with
dispersal of adults versus dispersal of juveniles,
local versus global density regulation, give radically
different evolutionary outcomes that include selection
for total philopatry, evolutionary bistability,
selection for intermediate stable states, and
evolutionary branching points. Our results highlight
the importance of accounting for life-cycle specifics
when predicting the effects of the environment on
evolutionarily selected trait values, such as
dispersal, as well as the need to check the robustness
of model conclusions against modifications of the life
cycle.},
