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

description: 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.
