Figure 1 in Interactions of daylength, temperature and nutrients affect thresholds for life stage transitions in the kelp Laminaria digitata (Phaeophyceae)

Figure 1: Effects of temperature, nutrient availability and daylength on gametophyte surface area of Laminaria digitata after 7 days. Values are expressed as the mean ± SE (n = 4). Dotted line represents the mean value of gametophyte surface area on day 0. Different letters indicate significant differences among the means for each temperature. See Table 1 for results of statistical analysis.
