Abstract
Most zoos keep comprehensive records, which potentially form a database for use in answering some research questions, such as in veterinary and population management research. They have not, however, been widely used to answer questions about animal behavior and welfare. Here we try to assess the usefulness to behavioral research of two sorts of zoo records (ARKS, the Animal Records Keeping System, and student dissertations held on file) to test the hypothesis that ring-tailed lemurs with a left limb preference experience more negative social lives. We found that, as predicted, lemurs with a left limb preference (LH) received more aggression and were involved in less grooming than nonleft-preferent lemurs (NLH), though the differences were not statistically significant. Contrary to prediction, LH lemurs had fewer reported woundings than NLH lemurs, but again the difference was not statistically significant. We found that the ARKS reports did not contain sufficient quantified and systematic behavioral data for our purposes, although otherwise they provided an excellent context for interpreting results. The student dissertations were also of limited use, primarily because of the small time frame in which they were carried out. Because of these shortcomings we were unable to distinguish whether our inability to find significant effects was due to biological (perhaps hand preference had no consequences for the lemurs) or data reasons. We suggest that closer liaison between zoo research staff, zoo record keepers and academic supervisors could help to improve the usefulness of zoo records for behavioral research.
