Plant responses to rainfall treatments: A C3:C4 plant cover ratio in response to season and rainfall, B total live (green) biomass C3:C4 ratio grouped by season and by rainfall and C total plant cover per plot across all species (C3 and C4), in both seasons and in both added and non-added herbivore plots. Fill for bars corresponds to rainfall treatments (Amb: ambient rainfall, RA: 50% reduced amount rainfall, RF: reduced frequency rainfall) and seasons. Opaque fill and hatching correspond to root herbivore status (RH+: root herbivores added, RH0: root herbivores not added). Error bars correspond to standard ± 1 error. Letters within panels A and B indicate post hoc comparisons without a herbivore treatment distinction. Within panel C, “·” indicates marginal significance between RH0 and RH+ plots within season
