Data from: Sex-specific responses to climate change in plants alter population sex ratio and performance

Males and females are ecologically distinct in many species, but whether
responses to climate change are sex-specific is unknown. We document
sex-specific responses to climate change in the plant Valeriana edulis
(valerian) over four decades and across its 1800m elevation range.
Increased elevation was associated with increased water availability and
female frequency, likely due to sex-specific water use efficiency and
survival. Recent aridification caused male frequency to move up-slope at
175 m/decade, a rate of trait shift outpacing reported species range
shifts by an order of magnitude. This increase in male frequency reduced
pollen limitation and increased seedset. Coupled with previous studies
reporting sex-specific arthropod communities, these results underscore the
importance of ecological differences between the sexes in mediating
biological responses to climate change.
