  1. Analysis was performed across 10 individuals (2–11 images each; n = 56 images); each image measured 212.55 × 212.55 μm. Mean cell area, mean cell number (count) per image, and calculated cell densities are given for each bacterial taxon for samples from the tip (older tissue) and base (young tissue) of blades at Tatoosh Island and from the center of blades at Squaxin Island. Standard deviation is shown in parentheses
