| Sumario: | This research project aimed to assess the relationship between floristic composition and soil factors soil of tropical rainforest in the Commune “Playa de Oro”. 23 sampling units (UM) were established for the analysis of the floristic composition and vegetation structure indicators used by sampling unit such as diameter, total height of individuals, species, family, abundance, frequency, dominance and IVI, while for plant biodiversity diversity and similarity indices were used; to establish the influence of soil factors on floristic composition soil samples were taken. To determine whether the floristic composition of the forest is related to soil factors analyzed, canonical correspondence analysis (CCA), which are techniques of multivariate ordination between environmental variables and the abundance of species, was performed. For both analysis (CCA), the first matrix with abundance data (floristic composition) was prepared, the one that best showed the distribution of the data was the abundance matrix is why it was decided to use in the analysis, it is also one of the most commonly used by ecologists matrices. A total of a total of 27 families, 64 species and 2489 individuals were recorded, with the Arecaceae, Moraceae and Mirysticacea the most representative, and Glusiaceae Chrysobalanaceae less representative family. The Importance Value Index within the sampling units of the study area exposed as the most representative species of greatest ecological or Wettinai utilis litle weight, Ocotea sp and Miconia Sp. With 52.55%, 17.87 % and 17.56% respectively, the distribution of diameter classes (20) the first class, range 0-5, was the highest number of individuals I present 1430, the analysis of the vertical structure revealed the presence of 3 layers, being the second, middle layer, the largest number of individuals (1080). |
