H1: Environmental Effect Gall richness differs between environments due to differences in the composition and structure of the plant community. Savanna and dry swamp greater gall richness. Forest and wet swamp lower richness. H2: Functional Diversity X Gall Richness --> Environments with greater functional diversity (FD) will have greater gall richness, regardless of the type of environment. FD explains more variation than taxonomic richness. H3: Phylogenetic Diversity X Gall Richness Phylogenetically more aggregated environments (closely related plants) will have greater gall richness. Savanna and dry swamp Lower phylogenetic diversity (PD), greater gall richness. Forest greater PD, lower richness. Linear regression plots as predictors for each hypothesis.
