Introduction How animals budget their time is a primary concern to ethologists. This budgeting is similar to animal economics; animals strive to use their resources in the most efficient manner. Individuals must choose between finding mates, foraging, migration, and many other types of behavior (Jane Brockmann). This time allocation also has evolutionary significance: animals which are better at managing their time and energy resources are more likely to live and reproduce successively. By studying the amount of time animals budget for various behaviors, ethologists can gain a better understanding of the importance of these behaviors. Therefore, time allocation studies are an integral part of ethological studies. C.E. Bryant, N.M.J. Rupniak, and S.D. Iverson conducted one interesting time allocation study on the effects of caging on primate aggression, published in 1988. They noticed that individuals caged alone promoted unusual behaviors such as pacing or self-biting. They then decided to film and study six male cynomogus monkeys ( Macaca fascicularis ) in various caged arrangements. The individuals were normally kept alone in individual cages, but the researchers would place pairs in a larger playpen and film them for thirty minutes. This film was then analyzed using computer software, which separated, timed, and recorded all the behaviors of the pair. This data was then compared to data gathered while the animals were caged individually. This experiment produced many interesting results. First, it revealed that the pairs in the playpen exhibited exploration or locomotion two to five times more than when alone. Also, the experiment discovered that social interaction was very small in either environment. Even when the pairs occupied the same cage, these interactions accounted for less than one minute of time. Resting behaviors occupied the largest amount of time.
