Descrição: dc.descriptionAntagonistic interactions are main ecological forces in terrestrial communities and include several examples involving plants and animals. The studies performed in the rupestrian grasslands have mostly focused on patterns of herbivory and on the effects of plant quality and natural enemies on insect herbivore abundance and distribution. Herbivory rates recorded for plants in this ecosystem are within the range proposed for open areas (ca. 15 %), although a wider range of studies are still needed. Galling insect richness is highly variable amongst sites (between18and241species)andaremostlyrichandabundant inxerichabitats comparedtomesichabitats, corroboratingthehypothesisofenvironmentalharsh ness.Severalnewgallinginsectspecieshavebeendiscoveredinthisverydiverse landscape, indicating its importance for insect radiation and evolution.
