The response of species diversity (Shannon’s index) to predation and spatial structuring depends on whether antibiotic is present or not (N = 96). Antibiotic treatment (P < 0.0001) and spatial structure (P < 0.0001) both have a significant interaction with predation. Diversity was tested with a gls-model assuming group-specific residual variance
