Change Detection In Rhesus Monkeys and Humans
… of VWM. To this end, in the first aim, we tested monkeys and humans in virtually identical change detection tasks, where the subjects identified which memory item had changed between two displays. In addition to the typical manipulation of the number of items to-be-remembered (2-5 oriented bars), …

Ranging patterns and resource use in samango monkeys
… the ranging patterns and resource use of samango monkeys. Space use at both the species and group levels was largely determined by access to highly productive habitat, particularly tall-canopy, indigenous mistbelt forest. At the individual level, perceived predation risk strongly influenced the …

Change Detection Memory In Rhesus Monkeys and Humans
… (<em>Macaca mulatta</em>). Given that rhesus monkeys are the premier medical model for humans, it is important to understand their VSTM if they are to contribute to understanding human memory. The primary goals of this study were to train and test rhesus monkeys and humans in change detection …

Fission-Fusion Dynamics in Spider Monkeys in Belize
… members range in close proximity, but spider monkeys (Ateles) and chimpanzees (Pan) are known for their more fluid association patterns. These species have been traditionally described as living in fission-fusion societies, because they range in subgroups of frequently changing size and …

Behavioral Control of Seizures in Squirrel Monkeys (Saimiri sciureus)
… on sudden death. Procedures: eleven Squirrel monkeys were surgically implanted with depth electrodes. Electroencephalographic recordings were made and 38 days later lesions of the nodosa ganglia were created. Seizures were punished with electro stimulation and desirable behavior was positively …

Evolutionary history and taxonomy of the titi monkeys (callicebinae)
Titi monkeys (Callicebinae; Pitheciidae) are a diverse, species-rich group of New World primates with an extensive range across South America. They diverged from their sister clade (Pitheciinae) in the early Miocene, and thus, they comprise one of the oldest lineages of extant New World primates. …

Hormones and Body Size *Evolution in Old World Monkeys
This research shows that similar adult body size can be attained despite differences in levels of growth regulatory hormones during development. Results also demonstrate that absolute hormone levels during growth do not necessarily relate to adult size, contrary to the findings of previous research …

Anthropogenic influences on the behavioural ecology of urban vervet monkeys
… assess the behavioural ecology of urban vervet monkeys under quantified anthropogenic pressures, assessing both positive (human-food) and negative (human-aggression) consequences of urban living. We use the previously neglected interaction between positive and negative human influences to assess …

Spatial Mapping in Wild White -Faced Capuchin Monkeys (Cebus Capucinus)
… cognition, spatial memory, and the ability of monkeys to form mental maps of the location and distribution of feeding and resting sites across a forested landscape. Primates exploit home ranges that vary on spatial scales ranging from less than one hectare to several hundred hectares. However, …
