Environmental Enrichment

Quantitatively tested environmental enrichment options for singly-caged nonhuman primates: A review

Compatible companionship has a therapeutic effect on behavioral disorders, providing long- term stimulation of a great variety of species-typical social behavior patterns. Inanimate objects have little impact on behavioral disorders, but some of them provide appropriate means for the expression...

Long-term use of enrichment for paired and singly caged chimpanzees

Chimpanzees used televisions, balls, and mirrors for 0.27-1.53% of the observation time after several years of exposure to the enrichment items. Television and ball use were significantly higher than mirror use.

Primate facilities and environmental enrichment: An ecological and evolutionary perspective

The environmental enrichment program of the Caribbean Primate Research Center is guided by an evolutionary and ecological perspective. The evolutionary perspective suggests that primates should be housed in enclosures that provide a social and physical environment that resembles their natural...

An enriched environment for the African clawed frog (Xenopus laevis)

A continuous-flow aquatic housing system for frogs is described. Sandstones and a stainless-steel rabbit feeder were used for enrichment. The animals swam into the feeders immediately, and three of four animals usually occupy each feeder at any given time.
