Altitudinal filtering of large-tree species explains above-ground biomass variation in an Atlantic Central African rain forest por Gonmadje, C., Picard, N., Gourlet-Fleury, S., Réjou-Méchain, M., Freycon, V., Sunderland, Terry C.H., McKey, D., Doumenge, C.

“…While potential maximum tree height significantly decreased, wood specific gravity displayed no trend along the gradient. Finally, the decrease in above-ground biomass along the short altitudinal gradient can be at least partially explained by a shift in species composition, with large-tree species being filtered out at the highest altitudes. …”

Agro-morphological characterization and diversity analysis of Coffea arabica germplasm collection from INIA, Peru por Paredes Espinosa, Richard, Gutiérrez Reynoso, Dina Lida, Atoche Garay, Diego Fernando, Abad Romaní, Yudi Gertrudis, Girón Aguilar, Rita Carolina, Flores Torres, Itala, Montañez Artica, Ana Gabriela, Arbizu Berrocal, Carlos Irvin, Amasifuen Guerra, Carlos Alberto, Poemape Tuesta, Carlos Augusto, Guerrero Abad, Juan Carlos

“…Principal component analysis (PCA) showed that at least five of its principal components managed to explain 70.01% of the total variation in the collection. Finally, the high coefficients obtained for the phenotypic, genotypic and heritability variation confirm the existence of additive genes in the evaluated population, that would ensure the success of coffee breeding programs based on the selection of traits of agronomic importance.…”

Economic profitability of carbon sequestration of fine-aroma cacao agroforestry systems in Amazonas, Peru por Goñas Goñas, Malluri, Rojas Briceño, Nilton B., Gómez Fernández, Darwin, Iliquín Trigoso, Daniel, Atalaya Marin, Nilton, Cajas Bravo, Verónica, Díaz Valderrama, Jorge R., Maicelo Quintana, Jorge L., Oliva Cruz, Manuel

“…For this purpose, 53 small cocoa producers of the APROCAM cooperative were involved, from which data were obtained on the general characteristics of the production system, production and maintenance costs, indirect costs, and administrative costs; in addition, the costs of implementation and maintenance of an environmental services project were calculated to finally make a cash flow projected over 5 years. As part of the results, the economic analysis was carried out on 104.25 hectares of cocoa belonging to the total number of farmers evaluated, who reported an average yield of 957.32 kg of dry cocoa per he. …”
