Affiliation promotes the transmission of a social custom: handclasp grooming among captive chimpanzees

Handclasp grooming is a unique social custom, known to occur regularly among some, but not all populations of chimpanzees (Pan troglodytes). As with other cultural behaviors, it is assumed that this distinctive grooming posture is learned socially by one individual...

Positive reinforcement training affects hematologic and serum chemistry values in captive chimpanzees (Pan troglodytes)

Positive reinforcement training (PRT) techniques have received considerable attention for their stress reduction potential in the behavioral management of captive nonhuman primates. However, few published empirical studies have provided physiological data to support this position. To address this issue, PRT...

Positive reinforcement training and physiological responses in chimpanzees

A subset of variables potentially indicative of acute stress were analyzed to determine if the method of adminstration of anesthetic (voluntary present for injection compared with nonvoluntary injection) and/or the method of obtaining the blood sample (voluntary compared with anesthesized)...

Comparison of different enzyme-immunoassays for assessment of adrenocortical activity in primates based on fecal analysis

The overall aim of the present study was to assess the validity of four enzyme-immunoassays (EIAs) using antibodies raised against cortisol, corticosterone, and reduced cortisol metabolites (two group-specific antibodies) for assessing adrenocortical activity using fecal glucocorticoid metabolite (GCM) measurements in...

The use of positive reinforcement training in chimpanzees (Pan troglodytes) for voluntary presentation for IM injections

Positive reinforcement has been used to gain the cooperation of captive primates for research and management needs. In this study, ten chimpanzees .. were trained to present for intramuscular (IM) injections. Clicker training was used to teach subjects to present...

Use of space in a non-naturalistic environment by chimpanzees (Pan troglodytes) and lowland gorillas (Gorilla gorilla gorilla)

Chimpanzees preferred the highest tier of the enclosure and the gorillas preferred the floor level. Both species showed preferences for doorways, corners and the mesh barriers adjacent to keeper areas.
