When confronted with tasks involving reasoning instead of simple learning through trial and error, lemurs appeared to be less competent than simians. Our study aims to investigate lemurs' capability for transitive inference, a form of deductive reaso

Deceptive behavior in primates has been the focus of a number of studies. Nevertheless, such abilities have never been demonstrated in prosimians. The authors' goal was to analyze possible deception in lemurs according to a paradigm used with simians

Intra-population variations in home range size can be considerable among carnivores, especially in the red fox (Vulpes vulpes). In this species, variations are not necessarily sex or age dependent. Our aim was to test whether differences in home rang
