Starvation's role in plankton metabolism

[EN]Starvation at all scales of plankton from archaea to medusae is the prevailing condition in marine ecosystems. Such nutrient-limitation will shift the physiological state in these organisms with accompanying changes in their physiology and biochemistry. Here, we review our laboratory’s progress in documenting these changes associated with starvation in a range of marine organisms. Specifically, we focused on respiration, ammonium excretion, CO2 production, RQ, respiratory ETS activity, isocitrate dehydrogenase and glutamate dehydrogenase activity in the mysid, Leptomysis lingvura, a dinoflagellate, Oxyrrhis marina and two bacteria, Vibrio natriegens, and Pseudomonas nautica
