Fig. 2. Process for developing collaborative research between the Nonuya indigenous community and western scientists while studying fruit production patterns and the role of animals in the spatial distribution patterns of tree species. The starting point is a distant relationship between western scientists and indigenous people. From top to bottom the process consists on four main stages that indicate how this relationship with indigenous people, participating as passive guides, and little knowledge exchange developed into a collaborative-research relationship of high knowledge exchange. On the left side of the figure the sequence of knowledge gain. On the right side the increase of knowledge exchange.
