| Abstract: | This study explores the relations between captive and noncaptive (literature-reported wild) adult weights in 53 anthropoid primate species. Based on recent studies of variation in growth among wild populations, it is expected that captive and wild weights are highly correlated. In addition, the lack of a relation between species size and captive and wild weights is anticipated. Differences between wild and captive weights are investigated. Correlations between captive and wild weights are high. Within groups of closely related species, correlations can be expected to average r = .95 for both males and females. At low taxonomic levels (within genera), correlations are not generally as high. However, captive and noncaptive intrageneric correlations are comparable to intrageneric correlations based solely on wild weights reported by different literature sources. Size appears to be unrelated to differences in captive and wild weights. Species that appear to be at elevated risk of obesity are identified. This analysis finds that deviations between captive and wild weights are positively related to growth duration (measured for captive primates). This finding implies that, in long-growing species, wild weights may underestimate asymptotic size. Hypotheses explaining this phenomenon are developed. In general, extensive overlap in weight between samples of captive and wild primates is documented. © 1994 Wiley-Liss, Inc. |
