WebNPP = GPP - Ra. I also understand that the light bottle is measuring NPP, because it allows for both photosynthesis and cellular respiration. The dark bottle measures Ra because it only allows for respiration. Therefore, … WebNPP is a dynamic, inclusive and research-led department with broad expertise spanning receptor pharmacology, biophysics, circuits and systems neuroscience, cardiovascular neurophysiology and neural computation.
