Abstract
Few studies have investigated the long-term evolution of nutrient limitation in ecosystems developed on volcanic soils. To approach the problem, we used "space for time substitution" to compare sites with the same state factors, except for the time elapsed since disturbance. Forests of Conguillio National Park in southern of Chile occur on volcanic soils that developed from lava flows and ash deposits of different ages originated from the activity of Llaima volcano. In this study we evaluate the patterns of change in carbon, nitrogen and phosphorus in soils and leaves, as well as changes in tree diversity and basal area along a chronosequence of volcanic substra...
