Title Phylogenetic tree of the Asteraceae species
Downloaded 20 times
Description Plant phylogeny was constructed by combining the information from a composite tree of the Asteraceae family (Funk et al. 2009) for most genera, with taxonomy serving as a surrogate for phylogenetic relationships of nodes for which no information was available. When even the taxonomy was unable to provide relationships, unresolved nodes were left as polytomies. Species were also attached as polytomies deriving from each genus.

Title Phylogenetic tree of the endophagous insect species
Downloaded 16 times
Description This is an informal tree constructed by taxonomic substitution (sensu Bininda-Edmonds et al. 2001) of the available phylogenetic information for the insect species collected in our study. Starting with a purely taxonomic tree, we added information on the relationships between taxa whenever available (Supplementary material 1 Figure A1).

Title Asteraceae-Herbivore interaction network
Downloaded 14 times
Description Associations between Asteraceae and flower-head endophagous insects were assessed quantitatively in 20 remnants of Cerrado vegetation in southeastern Brazil (Almeida-Neto et al. 2011).The sampled sites were spaced from 0.6 to 41.4 km apart (mean distance = 16.3 km), at elevations ranging from 600 to 950 m. Plants and insects were sampled from April to May 2003. The sampling design consisted of 15 transects of 30m × 5m, randomly allocated in relation to the edge of the areas. We sampled flower heads from at least 20 individuals of each Asteraceae species, collecting about 80 mL of flower-heads per individual plant whenever available. In the laboratory, the flower-head samples were kept in plastic containers covered with a mesh lid. Adult herbivore emergence was checked at least weekly for a period of two months. We spent about four person-hours collecting flower-heads in each period and site. Further information on sampling, vegetation, and studied areas can be found in Almeida-Neto et al. (2010, 2011). For the purpose of this study, both species and their interactions were integrated into a single regional plant-herbivore network, depicting the presence or absence of interactions between each plant-herbivore pair. We only included in the regional interaction network the plant and insect species that occurred in at least five (25%) of the sampled areas. By constructing the network in this way, we aimed to minimize the effect of spatial mismatch on the structure of plant-herbivore interactions. Among the 1210 plant-herbivore pairs included in our network, only 12 do not co-occur in at least one site.
