Restraint in primate chair may cause unusual behavior in baboons: Electrocorticographic correlates and corrective effects of diazepam

The prolonged drowsy-like ECoG [electrocorticogram] and behaviour may therefore underline a reaction to the 'stress' conditions brought on by restraint.

Baboon behavior under crowded conditions

A stable breeding troop's living space - barren room - was reduced step-wise up to 50%, by means of a movable wall. Crowding produced sharp increases in aggression, noticeable increase in tension and general activity. Social disintegration [e.g., vicious aggression,...

Baboon sleeping site preferences and relationships to primate grouping patterns

Baboons select nocturnal roosts with characteristics which suggest that choices of alternatives are based primarily upon their degree of security from predation. Sites chosen, in decreasing order of preference, are steep cliff faces, emerging trees, closed canopy forest trees and...

Spatial pattern in a troop of yellow baboons (Papio cynocephalus) in Tanzania

Observations of adult and subadult yellow baboons (Papio cynocephalus) revealed class differences in spatial pattern both during movement and when at rest. males tended to spend slightly more time on the periphery than did females, and travelled more at the...

Infant-use by male gelada in agonistic contexts: agonistic buffering, progeny protection or soliciting support?

Two alternative theories have been proposed to explain why some male primates carry infants during agonistic encounters with other males. The first (agonistic buffering) suggests that males carry the infants of higher ranking opponents in order to defuse the latter's...
