Table 2 Summary of effects of habitat (either tide pool or emergent rock), grazing treatment (total exclusion, control, and procedural control), and randomly selected blocks on the temporal patterns of taxonomic richness, Shannon’s diversity, and the structure of periphyton rocky-shore communities

From: Independent effects of grazing and tide pool habitats on the early colonisation of an intertidal community on western Antarctic Peninsula
