| The complexity of nutrient distribution patterns in soils is a determinant environmental component of the structure of plant communities. Numerous insect species that interact with plants are associated with these communities, and some of these interactions result in the formation of unusual structures called galls. In this study, we investigated the relationship of galls, soil fertility and plant communities in three vegetation types, herbaceous restinga (HR), shrub restinga (SR) and shrub-tree restinga (STR), in an area of restinga in southern Brazil. We identified 217 species belonging to 159 genera and 82 families. The plant diversity recorded in the STR was 42.8% higher than the diversity in the other vegetation types. Gall richness increased... |

| Shade plants of ombrophilous forests are subjected to light-limiting conditions and need to invest in architectural structures associated with leaf symmetry to increase light capture. This study investigated the leaf architecture of six Araucaria forest tree species with distinct symmetry: Cupania vernalis, Casearia sylvestris, Schinus terebinthifolius, Piper gaudichaudianum, Roupala brasiliensis and Cedrela fissilis. We hypothesized that symmetry, associated with other traits, minimizes self-shading. Asymmetry index, petiole length, total leaf area, leaf angle, internode length and stem diameter were measured. The asymmetry index did not indicate a clear distinction between asymmetric and symmetric leaves. Leaves classified as asymmetric had higher... |
