Optimal foraging theory predicts effects of environmental enrichment in a group of adult golden lion tamarins
Abstract 10.1002/(SICI)1098-2361(1998)17:33.3.CO;2-F The success of environmental enrichment programs in effecting specific changes in the behavior of captive animals has not always been uniform. Separate studies demonstrated both an increase in food competition and a decrease in food competition among captive group-living primates upon introduction of foraging devices. The objectives of this study were to measure […]

Innovation has been defined as a solution to a novel problem or a novel solution to an old problem. The second part of this definition requires the inhibition of previously learnt solution strategies before a novel solution can be found. Therefore, inventing novel solutions for an old problem is considered to be particularly difficult. We […]
