Elementos arbóreos de los bosques de un plano inundable en el Parque Natural Tinigua, Colombia
We analyzed the floristic composition of a 0.9 ha sample of the Río Duda floodplain forest, Colombia. Plants > 10 cm diameter were included in the analysis. Two main communities were found in the area, one dominated by Guarea guidonia-Cecropia membrana cea and the other one by Laetia corymbulosa. The establishment of these communities is correlated to the intensity of flooding in the different zones of the floodplain. Floristic comparisons show strong affinities with the forests at Río Manú in southern Perú. The results support Gentry's hypothesis, that floristic affinities are determined by ecological similarities (such as soil fertility or rainfall) and not by other factors as geographical barriers or Pleistocene refugia.
