Enhanced transfer of organic matter to higher trophic levels caused by ocean acidification and its implications for export production: A mass balance approach
Fig 5
Time course of net changes of the element pools at ambient and high CO2.
Solid lines indicate temporal net changes (Δ values) of the element pools and net community production of (A–E) carbon, (F–J) nitrogen, and (K–O) phosphorus as average values of the ambient (blue) and high (red) CO2 mesocosms. Coloured areas indicate the standard deviation of replicated (n = 5) treatments. Roman numbers denote the four different phases of the experiment. Black asterisks identify significant CO2 effects (PERMANOVA, p <0.05).
