Effects of Temperature and pH on the Egg Production and Hatching Success of a Common Korean Copepod
The recent accelerated ocean acidification and global warming caused by increased atmospheric carbon dioxide may have an impact on the physiology and ecology of marine animals. This study was conducted to determine the egg production rate (EPR) and hatching success (EHS) of Acartia ohtsukai in respo...
