Variation in δ15N enrichment in Cerrado fragments: edge effects and morphophysiology of Bauhinia holophylla (Bongard) Steudel

Files and images of the published file in Annals of Botany. Large-scale agriculture has altered natural ecosystems, affecting nutrient availability for native plants. Nitrogen is often supplemented in the oligotrophic soils of the Cerrado with industrial fertilizers. Studies show that nitrogen can accumulate at the edges of native fragments near monocultures. However, research linking fragment size to nitrogen availability and plant physiological responses in Cerrado remains scarce. This study examined whether monocultures adjacent to Cerrado fragments introduce industrial nitrogen into conservation areas, and how it influences the physiological leaf traits of the native species, Bauhinia holophylla.
