Appendix F. Centrality metrics of Carcharhinus amblyrhynchos, C. albimarginatus, and C. leucas monitored in the central Great Barrier Reef.

Table F1. Centrality metrics of Carcharhinus amblyrhynchos, C. albimarginatus and C. leucas monitored in the central Great Barrier Reef. Node strength: relative number of incoming/outgoing movements from a reef; Closeness: central position in network space; Eigenvector - strategic placement a reef within the network; dPCintra - intra-patch connectivity; dPCflux - how well connected a patch was to another; dPC - sum of dPCintra and dPCflux; M - males; F - females; FL - fork length (cm). Tagged reef is indicated by *.
