In response to warming temperatures, many animal populations are migrating to higher elevations. Current distribution data, however, suggests that upslope dispersal is not occurring fast enough to keep pace with increasing temperatures. One possible explanation for this mismatch is that species lack the phenotypic plasticity to develop traits needed to overcome high elevations’ unusual physiological conditions, like extreme temperature variability, low oxygen availability, and intense UV radiation. Here, we tested this idea by reciprocally transplanting dragonfly larvae to low and high elevations in Colorado, USA and allowing them to develop to adulthood. Initial results indicate that low-elevation dragonfly species had improved hypoxia tolerance following development at high elevations, compared to when they developed at low elevations. These results suggest that low-elevation dragonfly species may have adapted developmental plasticity to these conditions. Additionally, dragonfly species from low and high elevations had similar chill coma recovery times and wing loading ratios, regardless of their elevation of development. Our results show that a lack of plasticity may not be preventing upslope range shifts, suggesting that the barriers may be earlier in the dispersal process (e.g., limitations to adults moving upslope and reproducing).
