Uncommon species diversity values in epiphytic diatom assemblages of the kelp Eisenia arborea

Macroalgae are an ideal substratum for multiple species of diatoms that are ingested along with their hosts by many species of grazers including abalones (Haliotis spp.). Much of the diet of abalones along the western coast of the Baja California peninsula (Mexico) depends on blades of the kelp Macr...
