Fig. 2From: Nested coevolutionary networks shape the ecological relationships of ticks, hosts, and the Lyme disease bacteria of the Borrelia burgdorferi (s.l.) complexThe distribution of the betweenness centrality and PageRank values of the tick species in the epidemiological Borrelia burgdorferi (BBG) network. This plot shows the number of clusters in which the ticks are allocated (indicated by the colours) and the phylogenetic diversity of the vertebrates of each tick species as measured using Faith’s phylogenetic diversity index (PD; indicated by the circle size). b shows an expanded view of the species in the square at the bottom left in a Back to article page
