dc.description.abstract | Adaptive explanations for dormancy often invoke bet
hedging, where reduced mean fitness can be adaptive if it associates
with reduced fitness variance. Sex allocation theory typically ignores
variance effects and focuses on mean fitness. For many cyclical parthenogens,
these themes become linked, as only sexually produced
eggs undergo the dormancy needed to survive harsh conditions. We
ask how sex allocation and the timing of sex evolve when this constraint
exists in the form of a trade-off between asexual reproduction and sexual
production of dormant eggs—the former being crucial for within-season
success and the latter for survival across seasons. We show that male production
can be temporally separated from or co-occur with sex, depending
on whether direct (time) or indirect (population density) cues
of the season’s end are available and whether population growth is density
dependent. Sex generally occurs late in the season but is induced earlier in
unpredictable environments. When only indirect cues are available, the
temporal spread of sex, and with it the production of dormant stages, is
even larger and, given sufficient mortality, leads to endogenous population
cycles in which frequent sex coincides with high densities. In all
scenarios, algorithms maximizing geometric mean fitness have reduced
fitness variance compared with a hypothetical non–bet hedger, confirming
that the timing of male production and sex in facultative seasonal
settings can be bet-hedging traits | fi |
