[Taste thresholds and above-threshold responses to fructose solution in relation to diet in Callitrichidae primates].
Taste thresholds and consumption responses to above-threshold concentrations of fructose solutions were determined in eight callitrichid primate species using the "two-bottle preference test". Although taste thresholds are relatively similar across species, above-threshold responses may differ considerably between marmosets and tamarins. As fructose concentration increases, the rate of consumption increases less for most marmoset species (Cebuella and Callithrix spp.) than for Goeldi's monkey (Callimico) and tamarins (Saguinus and Leontopithecus spp.). It is proposed that distinct shapes of the curves illustrating these responses characterize species in terms of global taste system adaptations to different diets.
