Secuestro de dióxido de carbono y emisión de oxígeno del bosque de Puerto Almendra, Loreto, Perú

Abstract

In this study, we quantified the gas exchange of Carbon Dioxide (CO2) and Oxygen (O2) in four species of trees located in the Puerto Almendras Arboretum “El Huayo”, Loreto Peru. The following species were subject to our study: Alchornea triplinervia, Parkia velutina, Cedrelinga cateniformis y Eschweilera grandifolia each species with a specific wood density ranging from very low density, low, medium and high density. The data was obtained through 4 forestry plot inventories of 1 hectare each. We calculated the biomass and volume applying allometric formulas established by the Intergovernmental Panel on Climate Change-IPCC. The results highlight that the densest species, E. grandifolia has the most sought out values in relation to CO2 sequestration, storage and oxygen production. Following E. grandifolia is C. cateniformis with medium density; meanwhile per hectare we found in E.grandifolia and A. triplinervia. The Tukey test and F test for ANOVA in the four study sites reveal a 0,05 level of confidence and is significant for all of the sources of proposed variables. Simultaneously the correlation analysis shows that the variables (timber density / Biomass), (timber density / CO2 storage), (timber density / CO2 capture) and (timber density / O2 emission) present a highly significant correlation (p = 0,0244) with a Pearson coefficient equal to r = 0,99751.
