Ayres devoted his life to the preservation of the unique biota and ecosystems of the Amazon, as well as to developing a method by which rural dwellers would benefit from the conservation of natural resources.[6] He realized that the uakari monkeys he had been studying for his doctoral thesis would stand no chance of survival unless new community-based models of natural resource management were applied to the much exploited Amazon river basin.[7]
Ayres's doctorate in primatology at Sidney Sussex College, Cambridge, in 1986 was for his thesis Uakaris and Amazonian flooded forest, the field work for which was undertaken on the upper Amazon River floodplain, near Tefé.[8]
