Comparación de la densidad básica vertical en fustes a tres diferentes alturas en especies forestales de la Amazonía ecuatoriana entre las zonas de vida: bosque siempre verde montano bajo y bosque siempre verde pie montano del norte de la cordillera oriental de los Andes, Cantón Tena, Provincia de Napo, año 2019.

The present investigation was carried out in Tena province of Napo, the purpose of the research was to take samples in permanent plots already established for which we need the help of two instruments, Pilodyn and Barreno Pressler; the Pilodyn helped us to know the hardness of the wood of each species since it shoots a metallic needle that gives us a reading in g / cc, the more the needle enters, the lower its hardness or density and the lower the reading the hardness of the tree, the readings were made at 1.10, 4 and 7 meters, the Barreno Pressler helps us to obtain a sample of wood or test piece that will help us to know the density, this test piece is measured in field its length with the help of a calibrator and packaged for later in the laboratory, take them to the stove and leave the samples for 24 hours at 105 ° C, then weighed them and by means of the basic density formula the density of each of the species studied was obtained, then in Excel, a linear regression was performed, the type of relationship between the two quantitative variables was obtained and, using the equation of the line, the data of the densities of 4 and 7 meters were obtained.
