Figure 3. Possible light limitation patterns.

Figure 3

A) Light limitation: a lower response to the Ctrl and +NP treatments when incubated under in situ light conditions and no difference between the Ctrl and +NP treatment when incubated with in situ light. B) Co light-nutrient limitation: the +NP treatment response is greater than the Ctrl for both standard and in situ light, but responses to Ctrl and +NP treatments are lower under in situ light than standard light. C) No light limitation: no difference between in the in situ and standard light incubation for either the Ctrl or +NP treatment.
