Composición florística y estructura de la gradiente altitudinal (600-1000 m.s.n.m.) de un bosque siempreverde piemontano de la amazonia Ecuatoriana, año 2020

The floristic composition of the tropical forests of the world is so diverse, a characteristic that is attributed to the different edaphoclimatic parameters that significantly influence; At the global level, studies are constantly being carried out that have made it possible to determine the ecological importance of the various tree species, as well as how their structure is distributed. Our country is not the exception because in this opportunity this research has allowed us to obtain important results from the floristic component of the evergreen piedmont forest of the CIPCA. The present research was carried out in a Piedmont evergreen forest of the Amazonia Ecuatoriana, at the Center for Postgraduate Research and Amazon Conservation "CIPCA", of the Universidad Estatal Amazónica. localizada en la Provincia de Napo, en el Cantón “Carlos Julio Arosemena Tola”; 45 minutes from the Puyo - Tena road, at km 44 next to the mouth of the Piatúa and Anzu rivers. The general objective of the research was to determine the floristic composition and structure in the altitudinal gradient (601-1000 m.a.s.l.). The research was diagnostic and descriptive. The information used in the research came from primary sources. To carry out the sampling of the trees, transects of 100 m long and 10 m wide were established, in which the name of the species, the DBH and the heights of all the individuals with DBH greater than or equal to 10 cm were recorded. The result was a total record of 538 individuals conforming 41 families, 131 species, the family with the highest number of species was Moraceae with 18 species (13.74%). The horizontal structure 5 diameter classes were established, the largest number of these are concentrated in the first class that ranges from 10.0 to 20.0 cm DBH represents 65.8% of the total number of individuals. However, the vertical structure determined that stratum number 2 (10.1 to 20.0 m) with 67.27%, is the most representative interval. The abundance at the family level with the highest number of individuals is Arecaceae with 107 individuals (19.89%), the family with the highest IVIF is Arecaceae (35.70%), the IVI in species is Iriartea deltoidea with 84 individuals (15.61%) and an IVIE of 23.52. Keywords: Floristic composition, similarity index, structure, altitudinal gradient.
