Viral attack exacerbates the susceptibility of a bloom‐forming alga to ocean acidification
Abstract Both ocean acidification and viral infection bring about changes in marine phytoplankton physiological activities and community composition. However, little information is available on how the relationship between phytoplankton and viruses may be affected by ocean acidification and what imp...
