Mean (+ SE) A) shoot density B) epiphyte biomass per core and C) aboveground biomass per core among 3 seagrass species.
Figure 2.
Mean epiphyte pixel volume (+SE) standarzied to seagrass leaf surface area (247 mm2), detected by flourometry among 3 seagrass species.
A) red-excited fluorescence B) green-excited fluorescence and C) ratio of red to green fluorescence. Red-excited fluorescence detects all photosynthetic organisms, green-excited fluorescence detects primarily red algae but also diatoms and some cyanobacteria.
