The rich records of Rhesus macaques at Cayo Santiago (CS) with detailed information of individual and family relationships enables extended genetic analyses of the reproductive history of the colony. As a part of a collaborative effort to build a Knowledge Model of the history of health of the CS Rhesus colony, this study further delves into the intricate social group interactions and reproduction dynamics to provide an integrated perspective for a deeper understanding of familial connections and genetic aggregations. Leveraging matrilineal lineage developed from previous work and patrilineal tracing made available since mid-1970’s, as well as inter-group transfer data, this study attempted to provide retrospective views of group evolution history, with an emphasis on dyad interactions regarding their natal and transferred groups. Employing tools and techniques popular in social community analysis, including graph database and Gephi, this study conducted a comparative analysis focused on animals born between 2005 and 2014. Preliminary results indicated that communities identified by using Gephi matched well with census records, while deviations from historical sketches of group evolution summaries existed as well. Upcoming results from using Neo4j, a graph database system, will be compared with these findings, which can be integrated more smoothly with CSViewer for Analysts, the graphical user interfaces for the CS Knowledge Model to be introduced in a workshop at AABA 2024 annual meeting. Findings of this research can help add one more perspective to pathological studies seeking correlations with environmental factors such as food provision and natural disasters like hurricanes.
