2014/4/4
In natural samples from the New Jersey coast and the Gulf of Alaska, zinc (Zn) and cadmium (Cd) uptake
rates by phytoplankton decreased on average about 30% as pH was decreased from 8.5 to 7.9 or 7.7...
Does warming enhance the effect of microzooplankton grazing on marine phytoplankton in the ocean?
