...Michaël Beaulieu; Kristin Franke; Klaus Fischer ABSTRACT In ripe fruit, energy mostly derives from sugar, while in over-ripe fruit, it also comes from ethanol. Such ripeness differences may alter the fitness benefits associated with frugivory if animals are unable to degrade ethanol when consuming...

... frugivory fruit ripening fig evolution Kibale Uganda It is a long-standing hypothesis that primate trichromacy evolved to aid frugivory ( Allen, 1879 ; Mollon, 1991 ; Polyak, 1957 ). Not only must frugivorous primates find fruits in foliage, they must discern whether they are ripe. Many...

... the background against which these diet items must be found. We plotted these measured stimuli in colour spaces appropriate for each primate species, and found that both frugivory and folivory are facilitated by the extra dimension of colour vision found in catarrhines but lacking in most other mammals...
