| Abstract: | The accumulation of chemical elements in biological compartments is one of the strategies of tropical species to adapt to
a low-nutrient soil. This study focuses on the Atlantic Forest because of its eco-environmental importance as a natural reservoir
of chemical elements. About 20 elements were determined by INAA in leaf, soil, litter and epiphyte compartments. There was
no seasonality for chemical element concentrations in leaves, which probably indicated the maintainance of chemical elements
in this compartment. Considering the estimated quantities, past deforestation events could have released large amounts of
chemical elements to the environment. |
