Ocean warming and acidification (OA) may alter the fitness of species in marine pelagic ecosystems through community effects or direct physiological impacts. We used the zooplanktonic appendicularian,  Oikopleura dioica , to assess temperature and pH effects at mesocosm and microcosm scales. In mesocosms, both OA and warming positively impacted  O .  dioica  abundance over successive generations. In microcosms, the positive impact of OA, was observed to result from increased fecundity. In contrast, increased pH, observed for example during phytoplankton blooms, reduced fecundity. Oocyte fertility and juvenile development were equivalent under all pH conditions, indicating that the positive effect of lower pH on  O .  dioica  abundance was principally due to increased egg number. This effect was influenced by food quantity and quality, supporting possible improved digestion and assimilation at lowered pH. Higher temperature resulted in more rapid growth, faster maturation and earlier reproduction. Thus, increased temperature and reduced pH had significant positive impacts on  O .  dioica  fitness through increased fecundity and shortened generation time, suggesting that predicted future ocean conditions may favour this zooplankton species.
