Fig. 2 Comparison of marginal effects on different diversity indices (both taxonomic and functional). The graphs are shown only for models revealing very strong, strong and moderate evidence of effects. For models with no interactions (a-e): Results with P<0.05 are represented by lowercase letters, levels sharing a letter have no evidence of being affected. For models with interactions (f-g): (f) FSpe: Results comparing prairie dog disturbance in the same grassland type are shown with p<0.05, evidence of effects between grassland types are indicated by lowercase letters. (g) RaoQ: Differences between prairie dog disturbance in the same season are shown with p<0.05, evidence of effects between WOP and WP in different seasons is shown with different capital letters that have the same number, evidence of effects between WOP in different seasons is shown with different lower case letters that have the number one, and evidence of effects between WP in different seasons is shown with different lower case letters that have the number two.
