The networks in our dataset were sampled in sites where the precipitation rate ranged from 15.53 to 433.82 mm. Our networks presented an average S of 27.83 ± 18.5 species (mean ± SD), involving an average 14.83 \(\pm\) 10.48 ant species and 13.41 \(\pm\) 10.00 plant species with EFNs. In the subset of networks where plant or ant species were identified, there was a large asymmetry in the number of plant and ant genera interacting in the networks (plants: 191 genera, ants = 44 genera in total). Regarding the ants, the most common genera interacting with the plants with EFNs were Camponotus (Formicinae) andPseudomyrmex (Pseudomyrmecinae) (17% and 12%, respectively). Plants genera, in turn, was more variable than ants in the interactions, with the most common genera being Cylindropuntia (Cactaceae) andAcacia (Fabaceae) (5% and 4% respectively).
