A simple ethological monitoring system to assess social stress in group-housed laboratory rhesus macaques

The increasing awareness of the importance of social housing of laboratory primates results in the establishment of group housing in many facilities. Our aim was to develop a set of manageable tools to allow continuous monitoring of social relations within...

Social anxiety, relationships and self-directed behaviour among wild female olive baboons

Self-directed behaviour (SDB) can be used as a behavioural indicator of stress and anxiety in nonhuman primates (Maestripieri et al. 1992, Animal Behaviour, 44, 967–979). We investigated the effect of nearest neighbours' relative dominance status on the SDB of sexually...

Comparison of confined mandrill (Mandrillus sphinx) behavior in traditional and ecologically representative exhibits

Behavior in a confined group of mandrills (Mandrillus sphinx) was compared before and after their move from a traditional, all indoor exhibit to an indoor/outdoor facility. The outdoor exhibit was designed to represent as well as is possible important features...
