• Response of cocoa trees (Theobroma cacao) to a 13-month desiccation period in Sulawesi, Indonesia (2010, background): “According to Zuidema et al. (2005), the rates of leaf production and abscission in Theobroma depend largely on the water and light regimes.”
• Experimental evidence for stronger cacao yield limitation by pollination than by plant resources (2010, background): “Limitation in nutrients, light and water can be expected to reduce the carrying capacity of cacao trees (Cunningham and Lamb, 1958; Cunningham and Arnold, 1962; Ahenkorah et al., 1987; Beer, 1988; Egbe and Adenikinju, 1990; Johns, 1999; Zuidema et al., 2005), and thus reduce the effective pollinator”
• Productivity of Theobroma cacao agroforestry systems with timber or legume service shade trees (2011, background): “…humidity and wind movement within the plantation, directly affecting photosynthesis, growth and yield of cocoa (de Almeida and Valle 2007; Zuidema et al. 2005); (2) favour or hamper the population dynamics and incidence of pests and diseases (and of their natural enemies) that reduce…”
• The physiological responses of cacao to the environment and the implications for climate change resilience. A review (2018, unknown): “Model simulations of cacao productivity identified annual radiation and dry season precipitation as accounting for 70% of the variation in bean yield in cacao (Zuidema et al. 2005).”
• Ecophysiology of the cacao tree (2007, background): “Using a simulation model, Zuidema et al. (2005) showed that annual radiation and rainfall during the dry season explained 70% of the variations in annual seed yields obtained for 30 sites along the tropical cacao producing areas of the world.”
• Shade tree effects in an 8-year-old cocoa agroforestry system: biomass and nutrient diagnosis of Theobroma cacao by vector analysis (2007, background): “However, light infiltration under all three species was within the optimal range for cocoa growth and pod yield, where growth is generally maximized at low shade levels as photosynthetic rates of cocoa decrease at high light intensities (Galyuon et al. 1996; Zuidema et al. 2005).”
• Effects of an experimental drought on the functioning of a cacao agroforestry system, Sulawesi, Indonesia (2010, methodology): “The physiological modeling study by Zuidema et al. (2005) suggested that droughts may induce yield reductions as high as 50% which is close to the result we observed in our experiment.”
• COCOA AND TOTAL SYSTEM YIELDS OF ORGANIC AND CONVENTIONAL AGROFORESTRY VS. MONOCULTURE SYSTEMS IN A LONG-TERM FIELD TRIAL IN BOLIVIA (2016, unknown): “Similarly as with trunk circumferences, the lower light interception in the AFs due to the overhead canopy of shade trees most probably explains the difference between the MONOs and the AFs best (Zuidema et al. , 2005).”
• The contribution of cacao agroforests to the conservation of lower canopy ant and beetle diversity in Indonesia (2007, background): “These studies mostly focused on insects (e.g., Armbrecht et al. 2005; Pineda et al. 2005; Shahabuddin et al. 2005) but such a large turnover from natural to cultivated forests has also been found for birds ( Waltert et al. 2004 ).”
• Shade tree management affects fruit abortion, insect pests and pathogens of cacao (2007, background): “%) in the study sites is considered dense agroforestry shade (Zuidema et al., 2005) and did not differ significantly between the three different shade tree types (ANOVA: F (2, 6) = 1.07, p = 0.40).”
• Climate change, cocoa migrations and deforestation in West Africa: What does the past tell us about the future? (2014, unknown): “Considering that West Africa has a drier climate than other major global cocoa origins and that this is considered a yield-limiting factor (Wood and Lass 2001; Zuidema et al. 2005), the prospect of higher rainfall should have been a major attractant to cocoa migrants.”
