Improving agroforestry systems in the humid tropics
... Cocoa- and coffee-based agroforestry systems are traditional production systems, which function in much the same way as forest. Compared to monoculture systems, they produce less cocoa or coffee, but they are more sustainable and environmentally friendly, since they are less intensive in terms of pe ...

Large Marine Carnivores: Trophic Cascades and Top
... Carnivores are predators that consume animals; herbivores are predators that consume plants. The effect of consumers on prey populations is measured as “interaction strength” (Paine 1980, 1992), which depends on more than just its abundance. We define per capita interaction strength as the effect of ...
