Transitive inference in two lemur species ( Eulemur macaco and Eulemur fulvus )
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 reasoning in which the subject deduces logical conclusions from preliminary information. Transitive inference may have an adaptative function, especially in species living in large, complex social groups a…
Aggressive and neutral interventions in conflicts in captive groups of brown lemurs ( Eulemur fulvus fulvus )
Third‐party interventions in conflicts have revealed complexity in primate social relationships. This type of intervention has seldom been analyzed in prosimians, although many of these species exhibit complex (multimale/multifemale) social organizations. The present study on captive brown lemurs ( Eulemur fulvus fulvus ) shows that dominant individuals were more likely to intervene in conflicts. Both males and females intervened aggressively in …
Do Ringtailed lemurs (Lemur catta) reconcile in the hour post-conflict?: A pilot study
Paternity Determination in Two Groups of Eulemur fulvus mayottensis: Implications for Understanding Mating Strategies
Social dominance and priority of access to drinking in Lemur macaco
Social dominance was analyzed in a group of Lemur macaco over a one-year period. A gonistic dominance was assessed by computing a dominance index for each individual in baseline conditions and in a competitive drinking situation, where success was measured as the amount of time in possession of the resource (a hottle of fruit juice). Dominance indexes during drinking competition were significantly correlated with baseline dominance indexes but we…
