Comparison of Posture and Substrate Use in Captive Callithrix jacchus and Saguinus fuscicollis

This research attempts to determine if there are any differences in the amount of time captive Callithrix jacchus, Saguinus fuscicollis use various substrates. Following a literature review, the primary hypothesis posited is there may be a possible correlation between time spent on substrate and feeding patterns. Recorded observations at the Marmoset Research Center-University of Tennessee Medical Center will be analyzed with a nonparametric statistical test in order to test this hypothesis.

While this study shows no significant differences between the species in the time spent on substrates, a secondary observation reflects differences in postures between Callithrix jacchus and Saguinus fuscicollis. Factors which may have an effect upon the results of this study will be discussed.
