Bacterial cell abundance of the surface biofilms of old and young tissue. Whole-mount images of kelp blade tip tissues (old) and base tissues (young) collected from the same kelp frond. Three individuals from different collection dates are shown. Older tissue from the tip of the kelp blade (A, B, C) is densely colonized compared to young tissue from the base of the blade (D, E, F). The same pattern is observed throughout the summer
