Elevation effects on the carbon budget of tropical mountain forests (S Ecuador): The role of the belowground compartment por Moser, G, Leuschner, C, Hertel, D., Graefe, Sophie, Soethe, N, Iost, S

“…In an altitudinal transect study in the South Ecuadorian Andes, we tested the hypotheses that (i) aboveground net primary production (ANPP) decreases continuously with elevation due to decreasing temperatures, whereas (ii) belowground productivity (BNPP) remains constant or even increases with elevation due to a shift from light to nutrient limitation of tree growth. …”

Promoting forest conservation through ecotourism income? por Wunder, Sven

“…This paper sets out a methodological framework for analysis of the alleged participation-income-conservation link, and applies it to the Cuyabeno Wildlife Reserve in the Ecuadorian Amazon region. Three Cuyabeno ethnic groups involved in tourism, the Quichuas, Siona-Secoyas and Cofans, are characterised by different tourism participation models, ranging from autonomous operations to pure salary employment. …”

Biological soil health indicators are sensitive to shade tree management in a young cacao (Theobroma cacao L.) production system por Visscher, Anna M., Chavez, Eduardo, Caicedo, Carlos, Tinoco, Leider, Pulleman, Mirjam

“…We assessed a series of soil health indicators in a five-year-old agroforestry trial located in the Ecuadorian Amazon. The following treatments: “control” (cacao monoculture), “timber” (cacao with Cedrelinga cateniformis Ducke; a leguminous tree), “fruit” (cacao with Bactris gasipaes), “N-fix” (cacao with Erythrina velutina Wild) and “mixed” (cacao with C. cateniformis + E. velutina) were replicated 3 times in randomized blocks. …”
