Stereotypy in monkeys and humans

Stereotyped movements are described in monkeys and humans and are classified as arising from constraint, sensory deprivation in infancy, amphetamine treatment or psychotic states. It is argued that, with the exception of cage stereotypies, stereotyped behaviour is evidence of abnormality...

Tool use by captive chimpanzees at an artificial termite mound

The design of a simple but effective termite mound is described. The artificial mound proved to be a viable simulation of the naturally occurring mounds, with most of the chimpanzees exploiting the food in the mound by using tools over...

A flexible restraint chair for the cynomolgus monkey (Macaca fascicularis)

There is a general consensus that restraint chairs should be used only where necessary, since they inherently cause monkeys physical and emotional stress. Authors found that the animals showed restless sleeping patterns which persisted despite our attempts to adapt the...

The reproductive physiology of the common marmoset Callithrix jacchus in captivity

Monkeys were adapted to a restraint device for blood sampling. Measurement of adrenocortical hormones and prolactin show that the animals are not affected by stress in these procedures [blood collection, palpation]. No supportive data are provided.

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...

Alloparental behavior in wild chimpanzees of the Mahale Mountains, Tanzania

Handling of smaller infants by individuals other than the mothers was studied for wild chimpanzees. Nulliparous subadult females, who are related or unrelated to the infants, are most earnest caretakers, while parous females usually are indifferent to infants other than...

Heart rate changes associated with tethering of cynomolgus monkeys

The results suggest that some amount of cardiovascular (and perhaps hormonal) disturbance may persist in tethered animals, even if several weeks are allowed for 'habituation'.
