- Influencia de las condiciones edáficas sobre la dominancia y diversidad de árboles en bosques pluviales tropicales del Chocó biogeográfico Harley Quinto-Mosquera Darlin Hurtado Julay Arboleda Biología Salero Opogodó Aluminum Pacurita phosphorus Introduction: The biogeographic Chocó presents an exuberant diversity of arboreal species; however, it is unknown if soils determine this diversity. Objective: Evaluate how edaphic conditions explain the diversity and arboreal dominance in tropical pluvial forests at a local scale. Methods: Seven permanent research plots were established in the forests of Opogodó, Pacurita and Salero. In these plots, tree diversity and dominance were measured, and edaphic conditions such as organic matter (OM), acidity, nutrients and texture were determined. Results: It was found that the diversity was much greater in Salero and Pacurita; but the dominance was greater in Opogodó. The diversity was positively related to phosphorus, aluminum, silt and clay; while, with pH, OM, calcium, magnesium, potassium and sand, the relationship was negative. On the other hand, dominance was negatively related to P and Al; while, the relationship was positive with pH, OM, Ca and sand. Conclusions: It was corroborated that the arboreal diversity is negatively related to some variables (Ca, Mg, K) of edaphic fertility. Apparently, edaphic infertility, acidity and aluminum toxicity, determine tree dynamics and diversity. 2019 artículo científico 0034-7744 https://www.redalyc.org/articulo.oa?id=44965908015 https://www.redalyc.org/journal/449/44965908015/ https://www.redalyc.org/journal/449/44965908015/html/ https://www.redalyc.org/journal/449/44965908015/44965908015.epub https://www.redalyc.org/journal/449/44965908015/movil DOI 10.15517/RBT.V67I6.37517 es http://www.redalyc.org/revista.oa?id=449 Revista de Biología Tropical application/pdf Universidad de Costa Rica Revista de Biología Tropical (Costa Rica) Num.6 Vol.67
