Figure S1 LRRX of fertilization (white squares), herbivore absence (black triangles) and their interaction (grey squares) on autotrophs as a function of: (a) dominant producer community type (phytoplankton, periphyton, macroalgae, herbaceous, woody); (b) consumer type (invertebrates, vertebrates, or both); (b) experimental method (enclosures, exclosures, or chemical/mechanical removal); and (c) experimental venue (field or lab).
Figure S2 Producer log response ratio LRR effect sizes for fertilization LRRF, herbivore absence LRRH, and their interaction LRRI as a function of (a) latitude (absolute value), (b) area of herbivore manipulation replicates (m2, ln-transformed), (c) study duration in days (ln-transformed).
Figure S3 Producer log response ratio LRR effect sizes for fertilization LRRF, herbivore absence LRRH, and their interaction LRRI as a function of (a) available N and (b) available P. Nutrient variables were standardized within systems by dividing by systems means.
Table S1 Parameter definitions and relative units (per standard area) for resource-autotroph-herbivore models (see Box 1).
