Patterns of shade plant diversity in four agroforestry systems across Central America: a meta‑analysis por Esquivel, M. Jimena, Vílchez-Mendoza, Sergio, Ospina Pedraza, Mayra A, Somarriba, Eduardo, Virginio Filho, Elias de Melo, Detlefsen Rivera, Guillermo, Casanoves, Fernando, y 5 autores más

“…Trees on pastures can potentially reach a similar species richness as cocoa and coffee systems but require sampled areas 7–30 times larger. In terms of composition, 29 species were shared across the agroforestry systems in different countries, illustrating the strong selection pressure of farmers for species that provide timber, firewood, and fruit. …”

Forecast models of coffee leaf rust symptoms and signs based on identified microclimatic combinations in coffee-based agroforestry systems in Costa Rica por Merle, Isabelle, Tixier, Philippe, Virginio Filho, Elías de Melo, Gilas, Chistian, Avelino, Jacques

“…However, the appearance of a symptom or sign can be influenced by complex combinations of meteorological variables acting at different times and for different durations. In our study, we monitored a total of 5400 coffee leaves during a year and a half, in different agroforestry systems, in order to detect the onset dates of the disease symptoms, such as lesion emergence, and signs, such as sporulation and infectious area increase. …”

Climate change adaptation and the agricultural sector in South American countries: Risk, vulnerabilities and opportunities por Taboada, Miguel Angel, Costantini, Alejandro Oscar, Busto, Mercedes, Bonatti, Michelle, Sieber, Stefan

“…Many adaptation measures show co-benefits with climate change mitigation or the prevention of land degradation and desertification, but other adaptation measures do not go in this direction. In the forthcoming times, the region’s rich natural resources are going to be subjected to strong market pressures and climate change threats. …”

An optimized purple corn cob extract as an ingredient for the development of maize-based extrudates with novel characteristics por Rolandelli, Guido, Favre, Leonardo Cristian, Aguirre-Calvo, Tatiana Rocío, Farroni, Abel Eduardo, Buera, María del Pilar, Dos Santos Ferreira, Cristina

“…The incorporation of Opt-PCC increased TPC and AA of the extrudates by 14 and 4 times, respectively. The results confirmed a significant increase in the functional properties and physical stability of the extrudates with the addition of Opt-PCC, encouraging its use as a natural ingredient in the development of novel foods with improved characteristics.…”
