dc.description.abstractParts of the nitrogen cycle involving two dominants (Lithraea caustica andQuillaja saponaria) in the Chilean piedmont matorral have been studied over a 15-month period. Analyses showed that 8.2 kg N ha?1 yr?1 entered the system in rainfall and dry deposition, though impaction of N-containing compounds on vegetation (not measured) may elevate this value.L. caustica, by virtue of its greater percent cover, contributed more leaf litter than didQ. saponaria to the system (1089,vs 737 kg dry matter ha?1 yr?1, respectively), although on an individual basisQ. saponaria produced more litter (640,vs 350 g dry leaf litter m?2 yr?1 rL. caustica). This plus the greater nitrogen release ofL. caustica leaf litter during decomposition (2.61,vs 0.60 g N kg dry litter?1 yr?1 forQ. saponaria) andQ. saponaria's higher N-content of dropped leaves (0.54,vs 0.37% N forL. caustica) may indicate a more external cycling of nitrogen inQ. saponaria relative to that inL. caustica. These two species may therefore represent two different strategies of individual nitrogen cycling, external and internal.
