Structural equation model showing the relationship between the abiotic environment, disturbance, plant functional traits and community-weighted means of animal body size for moths, bees, insectivorous and frugivorous birds.
Standardized coefficients are given for positive (solid lines) and negative (dashed lines) relationships. Double-headed arrows denote correlations of predictors. Dotted lines indicate hypothesized relationships that were not supported by the data, i.e. which turned out to be non-significant in the regression models. R2 values are marginal, i.e. give fixed effect explained variance. See S4 Table for unstandardized coefficients, individual P-values, and conditional R2 values. (a) Moths, (b) Bees, (c) Frugivorous birds, (d) Insectivorous birds
