Le principe toxique du bambou consommé par Hapalemur aureus n'est pas neutralisé par la terre ingérée

The toxicity of the bamboo shoots of Cephalostachium viguieri, eaten by Hapalemur aureus, has been tested before and after mixing the crushed plant material with the soil which is also consumed by the animal. Although in most instances, geophagy allows primates to detoxify plant secondary compounds such as tannins or glycoalkaloids, in the present case, the adsorption by the soil was not efficient. Other physiological or behavioral responses are still to be found to explain how the Golden Hapalemur copes with the bamboo toxicity.
