dc.description.abstractDifferent architectural arrangements may represent contrasting morphological solutions to different environmental pressures. This work aims to elucidate whether the crown architecture of Lychnophora ericoides (Asteraceae) modifies in response to harsh soil conditions (nutrient poor and heavy metal rich) and how its crown architecture affects its reproduction. One hundred and sixty L. ericoides individuals were randomly sampled from eight populations, four on quartzite and four on iron canga rocky complexes in the Iron Quadrangle, southeastern Brazil. We performed soil analyses to characterize edaphic differences and used eight morphometric parameters to describe the crown architecture of the plants. We calculated the population density and reproductive potential to verify the relationship between habitat, architecture, and fitness. Canga soils were more nutrient rich than quartzite soils and plants were architecturally distinct in each habitat. Plants established on canga soils were shorter, had a thinner main branch, and a smaller leaf than those established on quartzite soils. Moreover, plants on canga soils had a larger crown diameter and a greater number of branches and inflorescences. There was no difference in population density but the reproductive potential varied among populations and habitats. The crown architecture of L. ericoides closely relates to reproductive potential and may favor the reproduction of more architectonically complex plants, regardless of habitat.pt_BR
