The Ulva spp. Conundrum: What Does the Ecophysiology of Southern Atlantic Specimens Tell Us?

Figure 1

Photosynthetic capacities of the three species of Ulva under two temperature conditions (based on the effective quantum yield of PSII measurements). Data from different nutrient conditions and plots (Erlenmeyer flasks where individuals were incubated) were pooled. n=30. Standard deviation values are not shown because of scale-bar limitation (left to right: 0.021, 0.023, 0.032, 0.019, 0.026, and 0.035).
