Figure 3
Protein content of Xenia umbellata colonies under experimental conditions: only temperature increase without PO4 addition (control), 1 µM PO4 + temperature increased from week 3 onwards (1 µM PO4), 2 µM PO4 + temperature increased (2 µM PO4), and 8 µM PO4 + temperature increased (8 µM PO4). Letters above bars indicate significant differences between weeks and letters within bars indicate significant differences within the treatment over time (p < 0.05, pairwise comparison t-test, Bonferroni adjustment). Error bars represent standard deviations. Dots represent the individually measured data points. The vertical line indicates the start of the temperature treatment and the average temperature for all tanks for the different time points is given on top of the graph.
