Analysis of tree interactions in a mixed Mediterranean pine stand using competition indices

摘要: Studying species interactions in mixed forests allows us to assess their potential benefits and adapt current silvicultural tools developed monospecific stands multi-specific stands. We analyzed tree a Pinus halepensis Mill. pinea L. plantation using individual neighborhood models competition indices that accounted for symmetric asymmetric competition, analyze whether the growth of each was better explained by or competition. also split into intra- interspecific forms, test effects on change based competitor identity. Finally, we P. trees had different responses When calculating indices, explored how spatial information size contributed quantification process. Competition measurements were optimized more precisely describe interactions. Results showed inclusion generated important improvements models. The main mode symmetric, which could be related water restrictions typical Mediterranean climate. Considering identity did not improve models, while measurement without discriminating competitors parsimonious similar indicating two cope with ways. However, lower average than period analyzed. suggest preventing onset intense processes help slow down long-term replacement have management systems share ecological niches but are capable generating goods services.
