Sperm motility of oysters from distinct populations differs in response to ocean acidification and freshening
Species' responses to climate change will reflect variability in the effects of physiological selection that future conditions impose. Here, we considered the effects of ocean acidification (increases in pCO2; 606, 925, 1250 µatm) and freshening (reductions in salinity; 33, 23, 13 PSU) on sperm...

Species' responses to climate change will reflect variability in the effects of physiological selection that future conditions impose.
