Última Decoupling of soil development and plant succession along a 60000 years chronosequence in Llaima Volcano, Chile RChHN GALLARDO,MARÍA-BELÉN; PÉREZ,CECILIA; NÚÑEZ-ÁVILA,MARIELA; ARMESTO,JUAN J.. 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 substrates from 50 to 60,000 years AP (eight sites). We assessed the evolution of N and P limitation in... Tipo: Journal article Palavras-chave: N/P ratio; Phosphorus; Primary succession; Retrogression; Volcanic soils.

Positive interactions among plants, such as the nurse effect, can attenuate environmental stress (e.g., drought) or reduce the intensity of perturbations (e.g., herbivory), thus enhancing the possibility of regeneration in natural systems. This study analyses the potential use of nurse plants for restoring artificial environments, such as mine hard-rock dumps. We evaluated seedling recruitment and survival in open areas and beneath the canopy of nurse shrubs, with and without grazing exclusion, on an abandoned copper tailings storage facility in north-central Chile. The nurse species was Baccharis linearis (Asteraceae), and seedling species were B. linearis, Haplopappus parvifolius (Asteraceae), Schismus arabicus (Poaceae), and several forb/grass taxa. A...
