Fig. 7From: Open networks from within: input or output betweenness centrality of nodes in directed networksIBC a and OBC b of each node in the same food web as in Fig. 6 are plotted against Hub score and Authority score, respectively. The red squares represent nodes whose IBC or OBC are judged to be significantly high in Fig. 6. The green points are the other non-significant nodes. Dotted lines are the best linear fits. The coefficients of determination are indicatedBack to article page
